Here’s the answer w explanation :)
Answer: 95.55%
--------------------------------
Work Shown:
A = event that copier A breaks down
B = event that copier B breaks down
P(A) = probability that copier A breaks down
P(A) = 2% = 0.02
P(B) = probability that copier B breaks down
P(B) = 2.5% = 0.025
P(neither break down) = (1-P(A))*(1-P(B))
P(neither break down) = (1-0.02)*(1-0.025)
P(neither break down) = 0.9555
P(neither break down) = 95.55%
Answer:
I believe the answer is 8.5 inches long
Step-by-step explanation:
we have to find out how long 1/4 × 34 is, since each 1/4 represents one of the 34 feet of the pools length.
34×.25 = 8.5

Answer:
option D. 126 cm
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem
Triangles PQR and XYZ are similar by AA Similarity Theorem
so
![\frac{XY}{PQ}=\frac{YZ}{QR}=\frac{XZ}{PR}](https://tex.z-dn.net/?f=%5Cfrac%7BXY%7D%7BPQ%7D%3D%5Cfrac%7BYZ%7D%7BQR%7D%3D%5Cfrac%7BXZ%7D%7BPR%7D)
Let
z ---> the scale factor
![z=\frac{XY}{PQ}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BXY%7D%7BPQ%7D)
substitute the given values
![z=\frac{30}{5}=6](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B30%7D%7B5%7D%3D6)
step 2
Find the perimeter of triangle XYZ
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z ----> the scale factor
p_1 ----> the perimeter of triangle XYZ
p_2 ---> the perimeter of triangle PQR
so
![z=\frac{p_1}{p_2}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bp_1%7D%7Bp_2%7D)
The perimeter of triangle PQR is
![p_2=5+10+6=21\ cm](https://tex.z-dn.net/?f=p_2%3D5%2B10%2B6%3D21%5C%20cm)
we have
![z=6\\p_2=21\ cm](https://tex.z-dn.net/?f=z%3D6%5C%5Cp_2%3D21%5C%20cm)
substitute
![6=\frac{p_1}{21}](https://tex.z-dn.net/?f=6%3D%5Cfrac%7Bp_1%7D%7B21%7D)
![p_1=6(21)=126\ cm](https://tex.z-dn.net/?f=p_1%3D6%2821%29%3D126%5C%20cm)
therefore
The perimeter of triangle XYZ is 126 cm
