Answer:
45
Step-by-step explanation:
....................
Hey there! I'm happy to help!
We see that the cupcakes are $2, but for every 8 you buy you get 1 free.
So, if we buy 8 cupcakes, we will be paying $16, but we will actually be receiving 9 donuts, so that means that for every $16 we pay, we get 9 donuts.
Let's see how many times $16 goes into $80.
80/16=5
So, this means that our $16 that gives us 9 donuts was done 5 times, which totals up to 80 dollars. Let's multiply our donuts now.
9*5=45
So, Fatimah will get 45 donuts during the promotion.

A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 640t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit
Answer:
20 seconds
Step-by-step explanation:
h(t) = -16t2 + 640t
to find the maximum value =>
h'(t) = 0
-32t + 640 = 0
-32(t -20)= 0
t-20 = 0
t = 20 seconds
Find derivative of h(t)
[tex]\\ \rm\longmapsto \dfrac{d}{dx}(-16t^2+640t)[/tex]
[tex]\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}[/tex]
[tex]\\ \rm\longmapsto -32t+640[/tex]
Now its be 0[tex]\\ \rm\longmapsto -32t+640=0[/tex]
[tex]\\ \rm\longmapsto -32t=-640[/tex]
[tex]\\ \rm\longmapsto t=\dfrac{-640}{-32}[/tex]
[tex]\\ \rm\longmapsto t=20s[/tex]
How can you convert 0.23 into a fraction?
Answer:
First take 0.23 as 0.23/1
Then Multiply the numerator and denominator by any number, Let us say 100
So it becomes,

Hi,
Answer is $0.19
Step-by-step explanation:-
We know that:-
15 dimes = $1.50
20 nickels = $1.00
8 quarters = $2.00
half dollar = $0.50
19 pennies = $0.19
Total = $5.19
Since Billy spended $5, so,
$5.19 - $5 = $0.19
Hope it helps you...

the length of a sandbox is three feet longer than it’s width. Write the expression that would represent the area of the sandbox.
Part A : D.)
Part B : Length of the sandbox is 10 feet.
Step-by-step explanation:
Given,
Perimeter = 29 ft
We need to find the equation for the perimeter and also the length of the sandbox.
Solution,
Let the width of the sandbox be 'w'.
Now as per question said;
The length of the sandbox is 1 foot longer than twice the width of the sandbox.
So we can say that;
Length =
Now we know that the perimeter is equal to the sum of twice of length and width.
framing in equation form, we get;
Perimeter =
we have given the perimeter, so on substituting the value, we get;
Hence The equation used to find the width is .
Now we solve for 'w'.
Applying distributive property, we get;
Subtracting both side by '2' we get
Dividing both side by 6 we get;
Width of the sandbox = 4.5 ft
Length of the sandbox =
Hence Length of the sandbox is 10 feet.
Find the circumference of a circle that has a diameter of 70 cm.
Answer:
70 pi cm
219.80 cm
219.9114858 cm
Step-by-step explanation:
The circumference of a circle is given by
C = pi*d
C = pi * 70cm
Using 3.14 for pi
C = 219.80cm
Using the pi button
219.9114858cm
Circumference of circle = 2πr
π = 3.14 r = diameter/2 ; 70/2 = 35Hence , r is 35 cm
r denotes radius of circle⇛Circumference of circle = 2πr
⇛Circumference of circle = 2*3.14*35
⇛Circumference of circle = 6.28*35
⇛Circumference of circle = 219.8 cm
Hence , Circumference of circle is 219.8 cm

5-81. Scientists hypothesized that dietary fiber would impact the blood cholesterol level of college students. They collected data and found r = -0.45 with a scattered residual plot. Interpret the scientists' findings in context. Hint: r stands for correlation coefficient)
Step-by-step explanation:
It shows that the content of dietary fiber is negatively correlated to the blood cholesterol of college student, as the correlation coefficient is negative. However, the r=-0.45 shows the two factors are lowly correlated (absolute value of r between 0.3 and 0.5)

Answer:
35 Degrees
Step-by-step explanation:
Angle JKL is reffering to the whole angle. The angle is split into two, it gives us the measurement for angle 1 which is 38 degrees. To find the answer we simply subtract angle m from angle JKL. 73-38 = 35... So angle 2 is 35 degrees.
