Answer:
ira can make 4 pizzas
Step-by-step explanation:
7.5*.2=1.5
- 1.5= 6.5 w/ 20% off
6.5*0.0525=0.34125- rounded= .34+6.5=
$6.84
Hope this helps!!!!
Answers:
- The direct variation equation is y = 5x
- If x = 4, then y = 20
=================================================
Explanation:
Let's say that the letter k replaces the green box
We have the equation y = kx
Plug in (x,y) = (7,35) to get the equation 35 = k*7
Dividing both sides by 7 leads to k = 5
Therefore, the direct variation equation is y = 5x
We can check this by plugging in x = 7
y = 5x
y = 5*7
y = 35
So x = 7 leads to y = 35 as expected.
-------------
Do the same for x = 4
y = 5x
y = 5*4
y = 20 when x = 4
Side note: direct variation equations always go through the origin.

Answer:
volume = 7 * 4 * 24 = 672 m 3
Step-by-step explanation:
a^2 = 25^2 - 7^2 = 576
-> a = 24
volume = 7 * 4 * 24 = 672 m 3
