Answer:
The weight of the box of candies is 1.5b kg greater than the weight of the watermelon.
Step-by-step explanation:
Let's begin by listing out the variables we were given:
weight of the watermelon = b (kg),
weight of watermelon = (2/5) * weight of candies
weight of candies = 1 ÷ (2/5) = 1 ÷ 0.4
weight of candies = 2.5b (kg)
How much is the weight of the box of candies greater than the weight of the watermelon is given by:
weight of the box of candies - weight of watermelon= 2.5b - b = 1.5b (kg)
Therefore, the weight of the box of candies is greater than the weight of the watermelon by 1.5b (kg)

Tony needs 16 inch-long pieces of gold chain to
make each of 3 necklaces. He has a piece of chain
that is feet long. How much chain will he
have left after making the necklaces?
O 6 inches
O 12 inches
18 inches
24 inches
Answer:
Option (1). 6 inches
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces ?
Tony has a piece of chain = 4.5 feet long
≈ 4.5 × 12 inches
≈ 54 inches
Number of necklaces Tony wants to make = 3
Length of every piece of gold chain required for one necklace = 16 inches
Total length of gold chain required for 3 necklaces = 3 × 16 inches
= 48 inches
Length of remaining chain = 54 - 48 = 6 inches
Therefore, Option (1) will be the answer.
David loves his dog Thor and he wants to create a rectangular enclosure that has an area of 1600ft² for the dog to stay in while no one is home. David has a total of 120 feet of fencing available and he wants to use the wall of his garage as one of the sides of the enclosure. What are the dimensions of the enclosure?
Make a Sketch of the rectangular enclosure and label the sides using variable(s).
Write and solve an equation(s) that model this situation.
What are the dimensions of the rectangular enclosure?
Answer:
80 feet by 20 feet
Step-by-step explanation:
Area of the rectangular enclosure = 1600ft²
Area, lw=1600
w=1600/l
Perimeter, 2w+l=120 feet
Substituting w=1600/l into the perimeter
2(1600/l)+l=120
3200/l+l=120
[tex]\dfrac{3200+l^2}{l}=120\\ 3200+l^2=120l\\l^2-120l+3200=0\\l^2-40l-80l+3200=0\\l(l-40)-80(l-40)=0\\(l-40)(l-80)=0\\l-40=0\:or\:l-80=0\\l=40\:or\:l=80[/tex]
When l=40, w=1600/40=40 feet
When l=80, w=1600/80=20 feet
Since the enclosure is rectangular, the acceptable dimensions are:
Length =80 feet
Width =20 feet

The radius of a sphere is 3 inches. Which represents the volume of the sphere?
Answer:
113.1
Step-by-step explanation:
V=4/3π(r)^3
V=4/3π(3)^3
V=4/3(27)π
V=36π ---> 113.1
The volume of a sphere is 4,186.67 cm cubed. To the nearest centimeter, what is the radius of the sphere? Use 3.14 for π.
A.8
B.5
C.10
Using the volume formula for a sphere (V = (4/3)πr3), the radius for the given volume of 4,186.67 cm3 is calculated to be 10 cm, making option C correct.
Explanation:The volume of a sphere is given by the formula V = (4/3)πr3. To find the radius of a sphere with a volume of 4,186.67 cm3, we rearrange the formula to solve for r:
r = ∛((3V) / (4π))
Substituting the given volume and 3.14 for π:
r = ∛[(3×4,186.67 cm3) / (4×3.14)]
r = ∛[(12,560.01 cm3) / (12.56)]
r = ∛(1,000)
r = 10 cm
So, to the nearest centimeter, the radius of the sphere is 10 centimeters, making option C the correct answer.

Answer:
d. The speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near to 153 mph.
Step-by-step explanation:
For the boxplot for Race A, the following is obtained from the attached diagram
The range of speed of the race is= Highest - Lowest
170 - 120= 50
The 1st Quartile is = 142
The 2nd Quartile is = 153

The Inter quartile range = 3rd quartile - 1st quartile = 165-142= 23
For the boxplot for Race B
The following values is obtained from the attached image.
The range of speed of the race is
Highest speed - Lowest speed
165 - 125= 40
The 1st Quartile is = 139
The 2nd Quartile is = 145
The 3rd Quartile is 150
The Inter quartile range = 3rd quartile- 1st quartile = 150 - 139 = 11
From the values above, we can see that ,
The speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near to 153 mph.
The common ratio of a geometric series is 3 and the sum of the first 8 terms is 3280.
What is the first term of the series?
Answer:
The first term of the geometric series is 1
Step-by-step explanation:
In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.
Mathematically, the sum of terms in a geometric series can be calculated as;
S = a(r^n-1)/( r-1)
where a is the first term that we are looking for
r is the common ratio which is 3 according to the question
n is the number of terms which is 8
S is the sum of the number of terms which is 3280 according to the question
Plugging these values, we have
3280 = a(3^8 -1)/(3-1)
3280 = a( 6561-1)/2
3280 = a(6560)/2
3280 = 3280a
a = 3280/3280
a = 1
Final answer:
To find the first term of a geometric series with a common ratio of 3 and a sum of the first 8 terms being 3280, we use the sum formula for a geometric series and isolate the first term 'a'. After plugging in the values and simplifying, we find that the first term 'a' is equal to 1.
Explanation:
The student is asking about the first term of a geometric series with a known common ratio and the sum of the first 8 terms. The common ratio for this series is 3, and the sum of the first 8 terms (S8) is 3280. To find the first term (a), we'll use the following formula for the sum of the first N terms of a geometric series:
S_N = a * (1 - x^N)/(1 - x),
where 'SN' is the sum of the first N terms, 'a' is the first term, 'x' is the common ratio, and 'N' is the number of terms. In this case, x=3 and S_8=3280.
Solving for 'a' gives us:
3280 = a * (1 - 3^8)/(1 - 3)
The first term (a) can now be calculated by isolating 'a' on one side of the equation.
a = 3280 / ((1 - 3^8)/(1 - 3))
a = 3280 / (1 - 6561)/(-2)
a = 3280 / (6560/2)
a = 3280 / 3280
a = 1.
Therefore, the first term of the geometric series is 1.

What are the domain and range of the function f(x)= 4 - 2x^2-4
A.) domain: all real numbers

B.) domain: all real numbers

C.) domain: all real numbers between –2.5 and 2.5
range: all real numbers
D.) domain: all real numbers between –2.5 and 2.5
range: all real numbers greater than or equal to –5
Answer:
If you meant to type f(x) = (4 - 2x)^2 - 4, then choose choice B.) domain: all real numbers
range: all real numbers greater than or equal to –4
----
With your typo... the choices narrow down to choice B and A. . The domain is definitely all real numbers for a quadratic function.
Step-by-step explanation:
We have a quadratic function
f(x) =4 -2*x^2 - 4
I assume there is a typo here.
check y >= -5 and y >= -4...
what if f(x) = (4 - 2x)^2 - 4
then f(x) = 4*(x - 2)^2 - 4 with vertex at (2, -4) which makes sense with the answer choice B.)
f(x) = 4*(xx - 4x + 4) - 4 = 4xx - 16x + 16 -4 = 4xx - 16x +12 ...
The domain of the function is all real numbers, and the range is all real numbers greater than or equal to -4.
The correct answer is option B.
Certainly, let's discuss the domain and range of the function f(x) = 4 - 2x^2 - 4 :
Domain (Possible x-values):
The domain of a function represents all the possible input values (x-values) for which the function is defined. In this case, f(x) is a polynomial function, and polynomial functions are defined for all real numbers. Therefore, the domain is all real numbers. So, options (A) and (B) are incorrect because they limit the domain.
Range (Possible y-values):
To determine the range, we need to analyze how the function behaves. The function f(x) = 4 - 2x^2 - 4 is a quadratic function with a leading coefficient of -2. It opens downward, and its vertex is at the point (0, 0). As x moves away from the vertex in either direction, the function value decreases without bound. Therefore, the range is all real numbers less than or equal to -4 because the function never goes above -4. So, options (C) and (D) are incorrect because they indicate that the range includes positive values.
Based on the analysis, the correct answer is:
B.) domain: all real numbers
range: all real numbers greater than or equal to -4

How many times does 2/3 go into 2?
Answer: 3 times
Step-by-step explanation:
2/(2/3)=3
Answer: 3 times.
Step-by-step explanation:
To find how many times 2/3 goes into 2, convert 2 to a fraction with the same denominator as 2/3.
You can do this by multiplying the fraction 2/1 by 3/3 to make the denominator equal 3:
[tex]\frac{2}{1}*\frac{3}{3} =\frac{6}{3}[/tex]
Then, you can divide the fractions. Because 6/3 and 2/3 have the same denominator, you can simply divide 6 by 2.
2/3 goes into 2 three times.

A full water tank holds 500 litres.
The tank begins to leak water and is losing 14% of its contents every hour. Find how much water is left in the tank after 8 hours.
Answer:
0 Litres
Step-by-step explanation:
If the tank holds 500 litres and its loosing 14% every hour, just multiply
14%x8h=112%
This means the tank has lost all of its water.
You can also do 500/100=5 <- 1% of the tank, then multiply it by 14 and it gives you 70 litres. Then, multiply this by 8 and its gonna be 560 litres. So this means the tanks is going to have 0 litres left at the end.
The quantity of water present in the tank after 8 hours will be 123.94 liters.
What is an exponential function?The mathematical expression f(x)=exp or e^x denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to complex numbers or adapted to other mathematical objects like matrices or Lie algebras.
Given that a full water tank holds 500 liters. The tank begins to leak water and is losing 14% of its contents every hour.
The quantity of water present in the tank will be,
W = 500 x ( 0.86)⁸
W = 500 x ( 0.2478)
W = 123.94 liters
Therefore, the quantity of water present in the tank after 8 hours will be 123.94 liters.

Kelly combines 6.54 ounces of strawberries with 6.09 ounces of blueberries to make fruit bowls.She pours the fruit equally into three bowls, and has 1.68 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answer:
3.65 ounces in each bowl
Step-by-step explanation:
Strawberry=6.54 ounces
Blueberry=6.09 ounces
If Kelly combines the two fruits to make fruits bowls
Then,
6.54 ounces of strawberry + 6.09 ounces of blueberry=12.63 ounces of fruits.
She pours the fruits equally in each bowl and has a leftover of 1.68 ounces.
Let quantity in each bowl = x
There are 3 bowls
Total quantity in three bowls=3x
Leftover=1.68
Total fruits = 12.63
We have the equation
3x+1.68=12.63
Subtract 1.68 from both sides
3x=12.63-1.68
3x= 10.95
Divide both sides by 3
x=10.95/3
x=3.65
Answer:
3.65 ounces of fruit in each bowl
Step-by-step explanation:
If the combination was made with 6.54 ounces of strawberries and 6.09 ounces of blueberries, the total ounces of fruit used is 6.54 + 6.09 = 12.63 ounces.
The remaining after dividing in three bowls is 1.68, so the amount used is 12.63 - 1.68 = 10.95 ounces
If we divide this amount of fruit by three bowls, we have:
Amount of fruit per bowl = 10.95 / 3 = 3.65 ounces
