There will be 23 layers of brick, because 7500/321 = 23 with 117 leftover.
Answer:
B. 12 + 2pi cm
Step-by-step explanation:
The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.
The circle's circumference can be found by using the equation c = (d)pi
The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.
Add them all together, and you get 12 + 2pi cm.
Answer:
Enlargement.
Scale Factor: 3
Step-by-step explanation:
Use points to find the enlargement. Typically, you will use all the points.
A(1 , 1) ⇒ A'(3 , 3)
B(2 , 1) ⇒ B'(6 , 3)
C(1 , 2) ⇒ C'(3 , 6)
D(2 , 2) ⇒ D'(6 , 6)
To find the scale factor, simply divide the Point' with the original Point. Use any number.
A'(3 , 3)/(A(1 , 1)) = 3
B'(6 , 3)/(B(2 , 1)) = 3
C'(3 , 6)/(C(1 , 2)) = 3
D'(6 , 6)/(D(2 , 2)) = 3
Your scale factor is 3.

The answer is
To figure this out, convert both numbers to fractions. 1.03 = 1
and (-10.3) = -10
. Now, convert to improper fractions.
1
![\frac{3}{100} = [tex] \frac{103}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B100%7D%20%20%3D%20%5Btex%5D%20%5Cfrac%7B103%7D%7B100%7D%20)
-10
=
Now, divide. Dividing fractions is the same as multiplying by the reciporical. So:
Y=6X+9 the A is #1
all you need to do is simp the equation
