Answer:
Step-by-step explanation:
6.
if they are similar ,then
8x+16=120
8x=104
x=13
7.
perimeter of Δ XZY=32+44+22=98
If they are similar then dilation=11/22=1/2
so perimeter of Δ BAC=98/2=49
Answer:77/292
Step-by-step explanation:
Answer:
Company X - 190 students
Company Y - 114 students
No phones - 76 students
Step-by-step explanation:
1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population
380/120 = 3.16666667 or 3 & 1/6
380 comes from the total population of students and 120 comes from the randomly selected.
2) Use our multiplier to compare the results to the population
<u>People with Company X</u>
<u>People with Company Y </u>
<u>People with no cell phone</u>
- 24 * 3.166667 = 76.0000000001 = 76 (rounded)
<u>Double check</u>
190 + 114 + 76 = 380
Answer:
B. x = 86, y = 75, z = 94
Step-by-step explanation:
As always, the sum of angles of a triangle is 180°. When two angles of a triangle are given, they can be subtracted from 180° to find the missing value.
x = 180 -35 -59 = 86
y = 180 -(35+11) -59 = 75
z = 180 -11 -75 = 94
_____
As a check, we must also have x+z=180.
