Answer:

1)42

5 times 8-8+10

=32+10

=42

2)107.6

42 times 9=378

32=160/5

378/5+160/5

=538/5

=107.6

3)9.375ft

(1.25)^2=1.5625

1.5625 times 6=9.375

4)3.5

49+7/16

=56/16

=3.5

5)1/64 cubic ft

1 times 1 times 1/4 times 4 times 4

1/64

Hope this helps!

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. 28. __________ If the number of pizzas varies dire

grandymaker [24]

Answer:

96 pizzas

Step-by-step explanation:

First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533

Convert 3 hours to minutes = 3 x 60 = 180 minutes

The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas

Write the slope-intercept form of the equation of the line

Monica [59]

Answer:

y =-5x-17

Step-by-step explanation:

Slode-intercept is

y = mx + c

The first step is to find the slope, that is the m

To do that, use this formula

Y2 - y1

------------

X2- x1

And u will get - 5

Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs

So let's say I chose (-4, 3)

So x = - 4, y = 3

y=mx +c

3= - 5(-4) +c

C = - 17

Therefore your end product will be

y = - 5x - 17

WILL MARK BRAINLIEST!!! HELP!

Virty [35]

Answer:

d) x=4

Step-by-step explanation:

$\sqrt{x} +5 = \sqrt{x + 45}$

$(\sqrt{x} +5)^{2} = (\sqrt{x + 45})^{2}$

$x + 10\sqrt{x} +25 = x + 45$

$10\sqrt{x} = 20$

divide 10 in both sides

$(\sqrt{x}){2} = (2){2}$

x=4
