Step-by-step explanation:
Answer:
5 d) 9 1/3
6 d) 2
Step-by-step explanation:
Proportions:
5
7 ⇒ 4
BY ⇒3
BY = 7*4/3
BY = 28/3
28/3 = 27/3 + 1/3 = 9 1/3
BY = 9 1/3
6
12 ⇒ 3
8 ⇒ SX
SX = 3*8/12
SX = 2
Answer:
length = 24 meters
Step-by-step explanation:
1. l = 2w
2. P = 2l + 2w
P=72
3. 72 = 2l + 2w
4. Substitute w=l/2 to solve for l
72 = 2l + 2(l/2) ---> 72 = 3L - Divide by 3 on both sides
L= 24 meters
Answer:
The next two terms are: 1.05 and 1.20
Step-by-step explanation:
Given

Required
Write out the next two terms
Since it is a linear sequence; first, we calculate the common difference (d)
or 
Express as decimals
or 
(in both cases)
So, we add 0.15 to 9/10, to get the next term



Add 0.15 to 1.05, to get the next term


<em>The next two terms are: 1.05 and 1.20</em>
Answer:
Part a) The exact area of the sidewalk is 
Part b) The approximate area of the sidewalk is 
Step-by-step explanation:
we know that
The area of the sidewalk is equal to the area of the outer circle minus the area of the inner circle
Part a) Find the exact area of the sidewalk

![A=\pi [144-64]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B144-64%5D)

Part b) Find the approximate area of the sidewalk
assume 
substitute
