Mathematics

Answer:

15pi

Step-by-step explanation:

assuming the rounded shapes are semi-circles, we can determine each of their perimeters by the known formula for a full-circle, and divide by 2.

the perimeter of a circle with radius r, is 2×pi×r, hence, a semi-circle, is pi×r.

now we need to find r.

for the given side-length, we simply divide by 2, and we get 2.5 and 6.

for the missinf side-length, we use the Pythagorean formula - a²+b²=c², where a=5 and b=12, we get c=13. hence the third radius is 6.5.

now, the total perimeter will be:

2.5pi+6pi+6.5pi=15pi

Which description explains how the graph of f(x)=√x could be transformed to form the graph of g(x) = √x-6
yawa3891 [41]

Answer:

b

c

Step-by-step explanation:

First question: x - 6 means there is a shift to the right.

Second Question: substitute the given values into the original equation for appropriate transformations.

Answer: 3 |x-4| + 2, because vertical stretch multiplies x, horizontal shifts are subtracted or added to x, and vertical shifts are added or subtracted to the entire function.

What is the area of this rectangle? A rectangle that is partitioned into two rectangles. The first rectangle has a measurement o
fiasKO [112]

Answer:

80 square meters

Step-by-step explanation:

A rectangle that is partitioned into two rectangles; rectangle A and rectangle B

Rectangle A:

Top = 5 meters

Side = 8 meters

Area of rectangle A = length × width

= 5 meters × 8 meters

= 40 meters ²

Rectangle B:

Top = 5 meters

Side = 8 meters

Area of rectangle B = length × width

= 5 meters × 8 meters

= 40 meters ²

Total area of the partitioned rectangle = area of rectangle A + area of rectangle B

= 40 meters ² + 40 meters ²

= 80 meters ²

If you sell 30 items at $200 a piece and your commission rate is 20%, how much commission do
jarptica [38.1K]

Answer:

$1200

Step-by-step explanation:

There are 2 ways I immediately think about to solving the problem.

1) You multiply 30 and 200 , then multiply the product by .2 (i.e. 20%)

This way, you'll find out what the total amount was($6,000), then you multiply it by your commission rate.(.2 or 20%) to find your total profit($1,200).

2) You multiply 200 by .20 , then multiply the product by 30.

This way, you'll find out what your commission would be for a single item($40), then multiply by the total items sold (30) to find your total profit($1,200).
