20% of 307.32 = 61.464 (Rounded to the nearest tenth, 61.46)
307.32 - 61.46 = $245.86
Answer:
1 = 56°
Explanation:
Interior angles 1 and 83° must add up to the external angle 139° because of the reason ‘exterior angles of a triangle’.
Angle 1+83°=139° (ext angles of triangle)
Angle 1 = 139°-83°
Angle 1 = 56°
Answer: 3.7 in.
Step-by-step explanation:
Given, A toy designer is creating a basketball plushy. The designer has fabric that measures 171.9 sq. in.
To find: The maximum radius of the basketball that the designer can create.
For this, Surface area of basketball = area of fabric
Formula: Surface area of sphere = 
, where r is the radius.
Then, 
Hence, the maximum radius of the basketball that the designer can create is 3.7 in.

i think its 79
Step-by-step explanation:sorry if im wrong because if i am then i did incorrect math
Answer: y = -6x -10
Step-by-step explanation:
The equation is y = mx + b
1. m is the slope so you can replace m with -6.
2. You are given a point, so you can replace variables x and y with the point. The equation should now look like this:
y = -6x + b
-4 = -6(-1) + b
3. Then multiply -6 and -1 to get 6. Now you are left with -4 = 6 + b
4. To solve for b you must get it alone. Right now B isn't alone because a 6 is being added to b. To get b alone you need to subtract 6. Now your equation should look like this: -4 - 6 = B
5. Get a calculator or use mental math and you will get B = -10.
6. Then plug b and m into y = mx + b, and you should get y = -6x - 10
