SOLUTION: The measure of angle 1 is five less than four times the measure of angle 2. If angle 1 are two form a linear pair, what are their measures. Question 345899: The measure of angle 1 is five less than four times the measure of angle 2. If angle 1 are two form a linear pair, what are their measures.
The y intercept of this line is -9
Answer:
Step-by-step explanation:
n=q-9
5n+25q=465, using n from above this becomes
5(q-9)+25q=465
5q-45+25q=465
30q-45=465
30q=510
q=17, and since n=q-9
n=17-9
n=8
So Melinda has 8 nickels and 17 quarters.
Answer:
a. 9,416.9 mm²
Step-by-step explanation:
Given:
Circumference of a sphere = 172 mm
Required:
Surface area of the sphere rounded to nearest tenth
Solution:
First, we need to determine the radius of the sphere since we know the circumference.
Circumference = 2πr
Plug in the value of the circumference
172 = 2*π*r
Divide both sides by 2π
172/2π = r
86/π = r
r ≈ 86/π
Next, find the surface area of the sphere
Surface area = 4πr²
plug in the value of r
Surface area = 4*π*(86/π)²
= 4*π*86²/π²
= 4*7,396/π
= 9,416.87967
≈ 9,416.9 mm² (nearest tenth)
