Answer: 32.5g of sugar
Step-by-step explanation:
if 1/2 cup of fruit cocktail is 13g of sugar then half of that, or 1/4 cup is going to be 6.5g of sugar. With that in mind, multiplying our 1/2 by 2 to give us one full cup of fruit cocktail will tell us that there is 26g of sugar in one cup. Adding our 1/4 cup to our whole cup will give us 32.5g of sugar in 1 1/4 cups of fruit cocktail.
Answer: There are 32.5g of sugar in 1 1/4 cup of fruit cocktail.
Step-by-step explanation:
13/2= 6.5
1/4 cups = 6.5g of sugar
6.5x5= 32.5g

Solve the equations. Show the solution sets on a number line. Check your answers. c 9k+3 =−4
Answer:
k = -7/9
Step-by-step explanation:
9k + 3 = -4
9k = -7
k = -7/9
On the number line just make a closed circle at -7/9. No line would be drawn, just the dot
-7/9 would be between 0 and -1, closer to -1
Answer:
k = -7/9
Step-by-step explanation:
If the equation is, 9k + 3 = -4, then;
9k =-4-3,
9k =-7,
k=-7/9
and on a number line just show a point with value -7/9, there is no inequality here
If an employer lacked 6 days of working twice as many days as did his employee and the sum of the days they worked is 42, how many days did each work
Answer:
Step-by-step explanation:
2x-6=48
2x=42+6
2x=48days
x=24days
The employee worked 16 days and the employer worked 26 days to reach the total of 42 days both worked.
Explanation:
This problem can be solved using algebraic expressions. Let's denote the number of days the employee worked as 'e'. According to the problem, the employer worked (e+6) days, since he lacked 6 days of working twice as many days as his employee (2e-6). Then, combining these gives the equation (2e-6) + e = 42 (the total number of days they both worked). We can simplify this equation by adding like terms and getting 3e - 6 = 42. Solving for 'e' will give us the number of days the employee worked. First, add 6 to both sides of the equation making it 3e = 48. Then, divide both sides by 3 to solve for 'e'. Thus, e = 16. This means the employee worked 16 days. The employer, having worked (2e-6) days, worked (2*16-6) = 26 days.

On the number line, a bug A is moving in the positive direction from the point 0, and a bug Bis moving in the negative direction from the point 0. The speeds of both bugs are constant. Both leave 0 at the same time, and three seconds later A has reached 18 and B has reached –15.
If x is the point reached by A after t seconds, and y is the point reached by Bafter t seconds, express x and y in terms of t.
Answer:
[tex]x=st[/tex]
[tex]y=-5t[/tex]
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
Let
s ----> the speed in units per second
d ---> the distance in units
t ---> is the time in seconds
BUG A
we have
[tex]d=18\ units[/tex]
[tex]t=3\ sec[/tex]
The speed is equal to
[tex]s=\frac{d}{t}[/tex]
substitute
[tex]s=\frac{18}{3}=6\ units/sec[/tex]
If x is the point reached by A after t seconds
then
Multiply the speed by the time
[tex]x=st[/tex]
[tex]x=6t[/tex]
BUG B
we have
[tex]d=-15\ units[/tex]
[tex]t=3\ sec[/tex]
The speed is equal to
[tex]s=\frac{d}{t}[/tex]
substitute
[tex]s=\frac{15}{3}=5\ units/sec[/tex]
If y is the point reached by B after t seconds
then
Multiply the speed by the time
[tex]y=st[/tex]
[tex]y=-5t[/tex] ----> is negative because B is moving in the negative direction
Answer:
x = 6t
y = 5t
Step-by-step explanation:
We know the distance formula:
D = RT
Where
D is distance
R is speed
T is time
Bug A went 18 units after 3 seconds, so the speed is:
18 = R(3)
R = 18/3
R = 6 unit/sec
Bug B went 15 units in 3 seconds, so the speed is:
15 = R(3)
R = 15/3
R = 5 units/sec
x is reached by A after 3 seconds, so
x = 6t
y is reached by B after 3 seconds, so
y = 5t

a sprinter increases the speed from 0 meters per second to 9 meters per second in 2 seconds. what is the acceleration
Answer:
The acceleration is
[tex]4.5 {ms}^{ - 2} [/tex]
Step-by-step explanation:
Use the equation of motion,
[tex]v = u + at[/tex]
where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.
We substitute the values into the equation and solve for the acceleration, a
[tex]9 = 0 + a(2)[/tex]
This means that;
[tex]9 = 2a[/tex]
Divide both sides by 2 to get:
[tex]a = \frac{9}{2} [/tex]
[tex]a = 4.5 {ms}^{ - 2} [/tex]
29.91 – 1.35p=-5.7(-6p - 4)
Answer:
p = 0.2
Step-by-step explanation:
Step 1: Distribute
29.91 - 1.35p = -5.7(-6p - 4)
29.91 - 1.35p = 34.2p + 22.8
Step 2: Add 1.35p to both sides
29.91 - 1.35p + 1.35p = 34.2p + 22.8 + 1.35p
29.91 = 35.55p + 22.8
Step 3: Subtract 22.8 from both sides
29.91 - 22.8 = 35.55p + 22.8 - 22.8
7.11 = 35.55p
Step 4: Divide both sides by 35.55
7.11 / 35.55 = 35.55p / 35.55
0.2 = p
Answer: p = 0.2

Assuming your system is:
[tex]x + 3y = 4[/tex]
[tex]3x - 5y = 8[/tex]
Then make x the subject in the first equation to get:
[tex]x = 4 - 3y[/tex]
Put this equation into the second equation to get:
[tex]3(4 - 3y) - 5y = 8[/tex]
[tex]12 - 9y - 5y = 8[/tex]
[tex] - 9y - 5y = 8 - 12[/tex]
[tex] -14y = - 4[/tex]
[tex]y = \frac{ - 4}{ - 14} = \frac{2}{7} [/tex]
This means that:
[tex]x = 4 - 3 \times \frac{2}{7} [/tex]
[tex]x = 4 - \frac{6}{7} = \frac{22}{7} [/tex]

Consider the two functions described below. Function 1 describes the cost, y, to park in a parking lot for x hours. There is a flat fee of $7.00 and $1.00 charge per hour. Function 2 is represented in the graph below. It shows the cost, y, to park in a parking garage, for x hours. Which statement correctly explains whether the parking lot or parking garage charges a higher rate per hour to park?
A. The parking lot charges a higher rate per hour because when you compare the rates, 7 4.
B. The parking garage charges a higher rate per hour because when you compare the rates, 2 1.
C. The parking lot charges a higher rate per hour because when you compare the rates, 7 2.
D. The parking garage charges a higher rate per hour because when you compare the rates, 4 1.
Statement B explains correctly that the parking garage charges a higher rate per hour than the parking lot. Statements B and D are the same.
Step-by-step explanation:
Step 1:
For the parking lot, there is a flat fee of $7.00 and then a charge of $1.00 every hour.
So if a vehicle was parked for 1 hour charges are 7 + 1 (1) = $8,
If parked for two hours charges are 7 + 1 (2) = $9.
Step 2;
To understand the pricing of the parking garage, we must plot the points of the graph.
The points on the graph are (0, 4), (1, 6), (2, 8), (3, 10), (4, 12), (5, 14)...
So for the parking garage, there is a flat fee of $4 and then a charge of $2.00 every hour.
So if a vehicle was parked for 1 hour charges are 4 + 2 (1) = $6,
If parked for two hours charges are 4 + 2 (2) = $8.
Step 3:
Comparing both the parking lot and the parking garage, we get that the flat fee for the parking lot is higher while the parking charges for an hour are higher for the parking garage which is statement B.
Statement B and D are the same.
Answer:
B

Which formula is best used to prove that a figure has congruent sides?
a) Slope formula
b)Area formula
c) Midpoint formula
d) Distance formula
Answer:
D
Step-by-step explanation:
Congruent sides mean that they have "EQUAL" lengths.
So, to prove to sides are congruent means that their lengths are equal.
Slope gives the slope of a line. So this can't be it.
Area gives the area of figure. Nothing to do with congruency of 2 lines.
Midpoint formula gives the coordinates of the midpoint. Nothing here.
Distance formula gives the length of sides. So, this is the one we can use to prove that a figure has congruent sides. We can place the figure in coordinate system and find the length of 2 respective sides using "distance formula"
Correct answer is D
If f(3) = -4, f'(3) = 4, g(3) = 2, and g'(3) = 0, find (f + g)'(3).
Final answer:
The derivative of the sum of functions f and g at x = 3 is calculated by adding the derivatives of f and g at 3. Given that f'(3) = 4 and g'(3) = 0, the derivative (f + g)'(3) equals 4.
Explanation:
The student is asking about the derivative of a sum of two functions at a specific point, which is a concept covered in calculus. From the given information, we know that:
f(3) = -4, f'(3) = 4g(3) = 2, g'(3) = 0To find (f + g)'(3), we apply the rule for the derivative of a sum of functions, which states that:
(f + g)'(x) = f'(x) + g'(x)
Therefore, (f + g)'(3) is:
(f + g)'(3) = f'(3) + g'(3)
(f + g)'(3) = 4 + 0
(f + g)'(3) = 4.
Thus, the derivative of the sum of functions f and g at x = 3 is 4.

Find the values of the variables and the measures of the angles
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are [tex]3x,[/tex] [tex]4x-1,[/tex] and [tex]90.[/tex]
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.
[tex]3x + 4x - 1 + 90 = 180.[/tex]
[tex]7x = 91, x = \frac{91}{7} = 13.[/tex]
So x = 13°. The angles are
[tex]3x = 3 (13) = 39, 4x-1 = 4(13) - 1 = 51.[/tex]
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
3x + 4x - 1 = 90⁰
7x = 91
x = 13
Angles are = 39 , 51⁰
