Answer:
b ≤ -4
Step-by-step explanation:
4b−4≤−20
4b - 4 + 4 ≤ - 20 + 4
4b ≤ -16
Divide both sides by 4
b ≤ -4
The answer is .277
Why:
Because first of all there are 26 letters in the alphabet then 10 numbers are given. so add those together; 26+10= 36
So 36 is the total and the fraction is 10/36
then divide
10/36= .277 about
Answer:
v=1
Step-by-step explanation:
v+(-16)=-15
v-16=-15
v=-15+16
v=1
Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
