Answer:
7. 49
8. 10.4
Step-by-step explanation:
7) our hypotenuse is 8, and the side opposite the base of ladder and ground angle is 6, therefore we can use Sin
sin = opposite/hypotenuse
sin(x) = 6/8 = 3/4
sin-1(3/4) = 49
8) using the theorem that alternate exterior angles are congruent
the angle opposite side x is 30
tan = opposite/adjacent
tan(30) = x/18
x = 18tan(30) = 6√(3) = 10.4
you can also use 30-60-90 special right triangles.
the side opposite 30 is x
side opposite 60 is x√(3)
and side opposite 90 is 2x
Answer:
5/12
7/12
125/36 = 3,47%
50/11 = 4,54%
Step-by-step explanation:
Probability a black sock is selected when a person chooses 1 sock = 5/12
Probability a white or brown sock is selected when a person chooses 1 sock =
7/12
Probability a person chooses 3 socks and selects a white first, a black second, and a brown last if the socks are replace = (4/12 * 5/12 * 3/12)*100 =125/36 = 3,47%
Pobability a person chooses 3 socks and selects a white first, a black second, and a brown last if the socks are NOT replace = (4/12 * 5/11 * 3/ 10)*100 = 50/11 = 4,54%
Answer:
You add them, then subtract them by how many numbers there are :) So add them then subtract them by 4
Step-by-step explanation:
Answer:
Percent change from 15 to 18.
You need to divide the numbers, but which one goes on top?
You know the number increases from 15 to 18, so the percentage must be greater than 100%.
The only way to get a number greater than 100% is to put the larger number on top.
Therefore, the answer is 18/15 = 1.2
Multiply by 100 to get a %
1.2 * 100 = 120%
2. Calculate percentage change
from V1 = 5 to V2 = 8
ans= 60%
overall answer gain of 15 yards and 18 yards
