1 in/2.54 cm = 90 in/? cm

nirvana33 [79]

1/2.54 = 90/x

Cross multiply
(1)x = (2.54)(90)

x would equal 228.6

The answer would be 90 in/ 228.6 cm.

Big Bob’s Pizza is having a special on pizza and is offering two different choices:

Anna71 [15]

Answer:

The Choice N#1 will give more pizza for your money

Step-by-step explanation:

step 1

Find the area of one slice Choice #1

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=22/2=11\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

The area of one slice is equal to

$A=(1/8)\pi r^{2}$

substitute

$A=(1/8)(3.14)(11)^{2}$

$A=47.4925\ in^{2}$

Divide the cost by the area

$4.95/47.4925=0.10\frac{\$}{in^{2}}$

step 2

Find the area of the entire personal pizza Choice # 2

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(3)^{2}$

$A=28.26\ in^{2}$

Divide the cost by the area

$3.75/28.26=0.13\frac{\$}{in^{2}}$

therefore

The Choice N#1 will give more pizza for your money

Two angles are supplementary (add up to 180 degrees). The measure of one angle is ten more than the other. Find the measure of e

Aleonysh [2.5K]

Answer:

85° and 95°

Step-by-step explanation:

So, one angle is x, the other angle is x + 10. Using this, you can form an equation.

x + x + 10 = 180

Now, solve the equation.

2x + 10 = 180

2x = 170

x = 85

So, one angle is 85 while the other angle is 95.

85 + 95 = 180,

so we know that our answer is correct.
