Final answer:
Mikey the monkey ate more bananas than Mick, consuming 5 compared to Mick's 4 bananas.
Explanation:
Let's calculate how many bananas each monkey ate. We'll start with Mick the monkey, who had 10 bananas and ate two fifths of them.
Calculate two fifths of 10 bananas: (2/5) × 10 = 4 bananas.
Mick therefore ate 4 bananas.
Now, let's calculate for Mikey the monkey, who also had 10 bananas and ate half of them.
Calculate half of 10 bananas: (1/2) × 10 = 5 bananas.
Mikey ate 5 bananas.
Mikey the monkey ate more bananas than Mick because 5 is greater than 4.

3x^+7x-6 factor completely
The factor for given equation [tex]3x^2+7x-6[/tex] is (3x-2) and (x+3).
Step-by-step explanation:
To find the factors of the equation,
1) Multiply the coefficient of the [tex]x^2[/tex] and the constant value.
⇒3×(-6)= -18.
2) Now find two numbers that can result is in -18 while multiplying and 7 (middle term or coefficient of x) while adding.
⇒9 × (-2) = -18.
9+(-2)= 7.
Now spit the equation as[tex]3x^2+9x-2x-6[/tex].
=[tex](3x^2+9x)-(2x-6)[/tex].
=3x(x+3) - 2(x+3).
=(x+3)(3x-2). (by taking out the common term x+3)
∴ The factor for given equation [tex]3x^2+7x-6[/tex] is (3x-2) and (x+3).
f(x) is a quadratic function with x-intercepts at (−1, 0) and (−3, 0). If the range of f(x) is [−4, ∞) and g(x) = 2x2 + 8x + 6, compare f(x) and g(x). Select the statement that is not correct?
A) Both functions have the same vertex.
B) Both functions have the same domain.
C) Both functions have the same x-intercepts.
D) Both functions are decreasing on the interval (−∞, −2).
Answer:
B) Both functions have the same domain.
C) Both functions have the same x-intercepts.
D) Both functions are decreasing on the interval (−∞, −2).
Step-by-step explanation:
step 1
Find the vertex of f(x)
we know that
The x-coordinate of the vertex is the midpoint of the roots
we have
x=-1 and x=-3
so
the midpoint is
(-1-3)/2=-2
The y-coordinate of the vertex is -4 (because the range is [−4, ∞))
therefore
The vertex of f(x) is the point (-2,-4)
Is a vertical parabola open upward
The vertex is a minimum
The domain is all real numbers
step 2
we have
[tex]g(x)=2x^2+8x+6[/tex]
Find the vertex
Factor the leading coefficient
[tex]g(x)=2(x^2+4x)+6[/tex]
Complete the square
[tex]g(x)=2(x^2+4x+4)+6-8[/tex]
[tex]g(x)=2(x^2+4x+4)-2[/tex]
Rewrite as perfect squares
[tex]g(x)=2(x+2)^2-2[/tex]
Is a vertical parabola open upward
The vertex is the point (-2,-2)
The domain is all real numbers
The range is the interval [−2, ∞)
Find the x-intercepts
For g(x)=0
[tex]0=2(x+2)^2-2[/tex]
[tex]2(x+2)^2=2[/tex]
[tex](x+2)^2=1\\x+2=\pm1\\x=-2\pm1[/tex]
so
The roots or x-intercepts are
x=-1 and x=-3
Verify each statement
A) Both functions have the same vertex
The statement is false
The vertex of f(x) is (-2,-4) and the vertex of g(x) is (-2,-2)
B) Both functions have the same domain.
The statement is true
The domain is all real numbers
C) Both functions have the same x-intercepts
The statement is true (see the explanation)
D) Both functions are decreasing on the interval (−∞, −2)
The statement is true
Because the x-coordinate of the vertex is the same in both functions, and both functions open upward

Kendra is three times her daughter's age plus seven years Kendra is 49 years old write an equation to find her daughter's age
Answer: [tex]49 = 3x + 7[/tex]
Step-by-step explanation:
Let the daughter's age be x and Kendra's age be y , then from the first statement;
[tex]y = 3x + 7[/tex]
Since Kendra's age is 49 , substitute it into the equation , we have
[tex]49 = 3x + 7[/tex]
subtract t from both sides
[tex]49 - 7 = 3x[/tex]
[tex]42 = 3x[/tex]
divide through by 3
[tex]x = 14[/tex]
Therefore : the daughter's age is 14
Answer:

If 2y + 6 = 1 −3y, then y = −−−−−−
Answer:
y = -1
Step-by-step explanation:
Add 3y to both sides:
2y + 3y + 6 = 1 - 3y + 3y
Simplify:
5y + 6 = 1
Subtract 6 from both sides to isolate the y value:
5y + 6 - 6 = 1 - 6
Simplify:
5y = -5
Divide by 5 on both sides to solve:
5y/5 = -5/5
Simplify:
y = -1
The Indian Ocean is 2/10 of the area of the world’s oceans. What fraction represents the area of the remaining oceans that make up the world’s ocean? Wrote in simplest form
Answer I believe it would just be 8/10
Step-by-step explanation:
You have 2/10 of the worlds ocean which = Indian Ocean
So Your remaining ocean (10-2 = 8)
Also known as 8/10
The remaining oceans make up 4/5 of the world's oceans after subtracting the 1/5 that represents the Indian Ocean.
If the Indian Ocean covers 2/10 (or 1/5 when simplified) of the world's oceans, then the fraction representing the remaining oceans is found by subtracting this fraction from the whole (1, as the whole represents all of the world's oceans).
So, the calculation to find the fraction of the area of the remaining oceans would be:
1 - 2/10 = 1 - 1/5 = 5/5 - 1/5 = 4/5
Therefore, the remaining oceans make up 4/5 of the area of the world's oceans.
Suppose a population has a doubling time of 25 years. By what factor will it grow in 25 years? 50 years? In 100 years?
A population with a doubling time of 25 years will grow by a factor of 2 in 25 years, by a factor of 4 in 50 years, and by a factor of 16 in 100 years, based on the exponential growth rule.
Explanation:If a population has a doubling time of 25 years, by what factor will it grow in various timeframes? Let's calculate this using the rule of exponential growth.
In 25 years, the factor by which the population will grow is 2, because the definition of doubling time implies that the population doubles every 25 years.
In 50 years, which is two doubling periods, the population will grow by a factor of 2^2 (2 raised to the power of 2), which is 4.
In 100 years, which is four doubling periods, the population growth factor will be 2^4 (2 raised to the power of 4), which equals 16.
Thus:
After 25 years, growth factor = 2After 50 years, growth factor = 4After 100 years, growth factor = 16Shawn's father gave him $168. Shawn bought 10 books, each of which cost $10. How much money does Shawn have left?

Angie makes a spicy salsa by adding red pepper flakes to a chunky tomato mix in proportional amounts. For example, she mixes 1/2 teaspoon of red pepper flakes to 2 cups of tomato mix.
Represent the relationship between red pepper flakes, in teaspoons, to tomato mix, in cups, in two different ways (table, graph, or equation)explain the variables
Answer:
[tex]y = \frac{1}{4}x[/tex]
x y
4 1
8 2

Step-by-step explanation:
Angie makes a spicy salsa by adding red pepper flakes to a chunky tomato mix in proportional amounts. For example, she mixes [tex]\frac{1}{2}[/tex] teaspoon of red pepper flakes to 2 cups of tomato mix.
So, the amount of tomato mix in cups is the independent variable represented by x and the amount of red pepper flakes in teaspoon is the dependent variable represented by y and the relation between them is given by y = kx, as the relation is proportional.
Now, putting x = 2 and y = [tex]\frac{1}{2}[/tex], we get
[tex]\frac{1}{2} = 2k[/tex]
⇒ k = [tex]\frac{1}{4}[/tex]
Therefore, the equation is [tex]y = \frac{1}{4}x[/tex] (Answer)
Now, in table the relation will be given by
x y
4 1
8 2
12 3
16 4 (Answer)
The relationship between red pepper flakes and tomato mix can be represented by a table showing different quantities matching the ratio, and by an equation, p = (1/4) * t, which expresses the amount of red pepper flakes (p) needed for any given amount of tomato mix (t).
To represent the relationship between red pepper flakes and tomato mix which Angie uses to make her spicy salsa, we will use a table and an equation.
Table Representation:
Red Pepper Flakes (teaspoons)Tomato Mix (cups)1/22141 1/2628
In the table, the amount of red pepper flakes increases proportionally with the amount of tomato mix. This proportional relationship can also be represented numerically.
Equation Representation:
Let's define p as the amount of red pepper flakes in teaspoons and t as the amount of tomato mix in cups. The ratio given is 1/2 teaspoon of red pepper flakes to 2 cups of tomato mix, which simplifies to 1/4 teaspoon per cup. Thus, the equation is:
p = (1/4) * t
This equation states that for every cup of tomato mix, you use 1/4 teaspoon of red pepper flakes. Therefore, if Angie has t cups of tomato mix, she will need p = (1/4) * t teaspoons of red pepper flakes.

T=42-0.7t how fast did the temperature drop?
The given equation describes a linear relationship between temperature and time. The slope, -0.7, indicates that the temperature is dropping at a rate of 0.7 degrees per unit of time.
Explanation:The equation given, T=42-0.7t, is in the form of a linear equation, y=mx+b, where T is the temperature in degrees Celsius, t is the time, 42 represents an initial temperature, and -0.7 is the slope representing the rate of temperature change over time.
In this equation, the slope, -0.7, tells us that the temperature is decreasing or dropping at a rate of 0.7 degrees per unit of time. This could be per minute, per hour, etc., depending on the context given.
Note that because the '-0.7' is negative, we know that the temperature is decreasing, or dropping, rather than increasing. If it were positive, it would mean the temperature is rising. Thus, when you're asked how fast the temperature is dropping, the answer based on this equation is that it's dropping at a rate of 0.7 degrees per unit of time.

#SPJ12
The temperature drops at a rate of 0.7 degrees per time unit, as indicated by the coefficient of t in the equation T = 42 - 0.7t.
The equation given, T = 42 - 0.7t, suggests a relationship between temperature (T) and time (t), where the temperature drops over time due to some cooling process, such as a cold front arriving. To determine how fast the temperature is dropping, we look at the coefficient of t in the equation, which is -0.7. This means that for every unit of time that passes, the temperature drops by 0.7 units. Thus, the rate of temperature drop is 0.7 degrees per time unit, assuming the temperature is measured in degrees and time in matching time units (likely minutes or seconds).

Final answer:
Scribes in medieval Europe had several important roles:
including copying books and religious material, keeping records and writing about current events,preserving learning and libraries.Explanation:
Scribes in medieval Europe had several important roles:
They copied books and other religious material: Scribes were responsible for hand-copying books, particularly ones related to Christian theology, such as the Bible. They also copied classical Greek or Roman writings that would have otherwise been lost. These hand-copied books, known as illuminated manuscripts, were often beautifully illustrated.They kept records and wrote about current events: Scribes also played a crucial role in keeping records and documenting current events. They wrote about important historical and political events, as well as religious and civil information.They preserved learning and libraries: Monasteries, where many scribes worked, became major centers of learning in medieval Europe. Scribes helped preserve knowledge from the ancient world by copying and preserving books. They also contributed to the development of libraries.Find two consecutive even integers such that the sun of the larger and twice the smaller is 62.

Write a multiplication equation and a subtraction equation that both involve a fraction and have the same solution. Solve your equation to show that the solution are the same.
Answer:
[tex]x = \frac{3}{5} \times \frac{5}{7}[/tex] and [tex]y = \frac{16}{21} - \frac{1}{3}[/tex]
Step-by-step explanation:
We have to write a multiplication equation and a subtraction equation that both involve a fraction and have the same solution.
Let the multiplication equation be, [tex]x = \frac{3}{5} \times \frac{5}{7}[/tex].
And the subtraction equation is, [tex]y = \frac{16}{21} - \frac{1}{3}[/tex]
Now, [tex]x = \frac{3}{5} \times \frac{5}{7} = \frac{3}{7}[/tex] and [tex]y = \frac{16}{21} - \frac{1}{3} = \frac{16 - 7}{21} = \frac{9}{21} = \frac{3}{7}[/tex]
Therefore, in both the equations the solution is [tex]\frac{3}{7}[/tex]. (Answer)
Final answer:
Both a multiplication equation (½ * 2 = 1) and a subtraction equation (1 - ½ = ½) can be constructed to have the same solution, where the multiplication involves doubling the fraction and the subtraction involves a whole number minus the fraction.
Explanation:
Creating a multiplication equation and a subtraction equation with the same solution involves finding a common value that the operations can share. Here's a simple example:
Let's say we have the fraction ½. If we want a multiplication equation, we could multiply this fraction by 2 to get 1 (since ½ * 2 = 1).
Multiplication equation: ½ * x = 1, where x = 2.
For the subtraction equation, we consider the fact that subtracting 0 from any number leaves it unchanged. We can use this to our advantage by creating an equation where we subtract a fraction from itself:
Subtraction equation: y - ½ = ½, where y = 1.
By solving these equations, we can see they have the same solution:
½ * 2 = 11 - ½ = ½Both equations simplify to the same value, demonstrating that multiplication and subtraction can indeed share the same result when formulated correctly.

The interior angles formed by the sides of a hexagon have measures that sum to 720°. What is the measure of angle F? Enter your answer in the box. m∠F= ° An irregular hexagon labeled ABCDEF with angle A parenthesis x minus sixty parenthesis degrees, angle B parenthesis X minus forty parenthesis degrees, angle C one hundred thirty degrees, D one hundred twenty degrees, E one hundred ten degrees, F parenthesis x minus twenty parenthesis degrees
Answer: [tex]m\angle F=140\°[/tex]
Step-by-step explanation:
The missing figure is attached.You know that the sum of the interior angles of an hexagon is 720 degrees.
Based on that and given the figure attached, you can set up the following equation:
[tex](x-60)+(x-40)+130+120+110+(x-20)=720[/tex]
The next step is to solve for "x" in order to find its value. This is:
[tex]x-60+x-40+130+120+110+x-20=720\\\\3x=720-240\\\\3x=480\\\\x=\frac{480}{3}\\\\x=160[/tex]
Now you must substitute the valUe of "x" calculated above, into [tex]m\angle F=(x-20)\°[/tex]:
[tex]m\angle F=(160-20)\°[/tex]
Finally, evaluating, you get that the measure of the angle F is:
[tex]m\angle F=140\°[/tex]

The first mechanic charged $95 per hours, and the second mechanic charged $70 per hour. The mechanics worked for a combined total of 25 hours, and together they charged a total of $2,000. How long did each mechanic work?
Answer:
Step-by-step explanation:
Let a represent the hours put in my mechanic 1 and b represent that of mechanic 2.
a + b = 25, i.e. a = 25 - b
95a + 70b = 2000
Let's substitute the value of a in the second equation
95(25 - b) + 70b = 2000
2375 - 95b + 70b = 2000
2375 - 25b = 2000
-25b = 2000 - 2375
-25b = -375
b = 375/25
b = 15hrs
If b = 15hrs,
a + 15 = 25
a = 10hrs
The school that Julia goes to is selling tickets to the annual dance competition. On the first day
of ticket sales the school sold 5 adult tickets and 13 child tickets for a total of $159. The school
took in $51 on the second day by selling 1 adult ticket and 5 child tickets. What is the price each
of one adult ticket and one child ticket?!
We have a system of equations in two variables, namely, a and c. Use the substitution to find a and c.
Answer:
The price of 1 adult ticket is $11, while the price of one child ticket is $8.
Step-by-step explanation:
Let's identify what we already know:
1) On the first day of ticket sales, the school sold $159 worth of tickets.
2) On the first day, they sold 5 adults tickets, and 13 adult tickets.
3) The school sold $51 worth of tickets on the second day.
4) The school sold 1 adult ticket, and 5 child tickets.
Let's create two formulas:
(5 times x) + (13 times y) = $159
(1 times x) + (5 times y) = $51
a food truck sells salad for $6.50 each and drinks for $2.00 each. The food truck's revenue from selling a total of 209 salads ans drinks in one day was $836.50. How many salads were sold that day?
Answer:
93
Step-by-step explanation:
s= salads d= drinks
$6.5s + $2d = $836.5
s + d =209
s = 209-d
6.5 (209-d) + 2d = 836.5
1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116
s = 209 - 116 = 93
