John’s age is 2 years more than twice Mary’s age, and the sum of their ages is 32 years. How old is each.
MAVERICK [17]

Answer:

John is 22; Mary is 10

Step-by-step explanation:

mary=m

john=2+2m

equation john + mary = 32

(2+2m) + m =32

3m+2 =32

3m=30

m=10

2m+2=?

2(10)+2=22

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 86m long and 64m wide. F
KIM [24]

To solve this problem, we have to find the area of the semi circles and the area of the rectangle and add them up together.

The area of the field is equal to 8719.36m^2

<h3>Area of the Field</h3>

Let us start by finding the area of the rectangle.

Data;

  • width = 86m
  • length = 64m

Area of a rectangle is given as

a = length * width \\a = 86 * 64\\a = 5504m^2\\

The area of the rectangle is 5504m^2

Area of the semicircle

The formula of a semi circle is given as

A = \frac{1}{2} \pi r^2

But since we have two semi circles here, we can simply multiply it by two and the formula becomes

A = 2 * \frac{1}{2} \pi r^2\\A = \pi r^2

But in the question, we have the diameter of the semi circle as the length of the rectangle.

radius = \frac{diameter}{2} \\radius = \frac{64}{2} \\radius = 32m

The radius of the semicircle is 32m

Area of the semicircle is

A = \pi r^2\\A = 3.14 * 32^2\\A = 3215.36m^2

The area of the field is

area of field = 3215.36 + 5504\\area = 8719.36m^2

The area of the field is equal to 8719.36m^2

Recall that two angles are complementary if the sum of their measures is 90°. Find the measures of two complementary angles if o
nordsb [41]

Answer:

18° and 72°

Step-by-step explanation:

The angle measures are unknown, so they will be represented with the variable, x.  Since, one angle is 4 times the other, this will be represented with 4x.

To find complementary angles, they are added together and equal 90. So let's create an equation.

x + 4x = 90

Now solve for x.

5x = 90

5x/5 = 90/5

x = 18

One angle is 18°.

Now find the second angle.

4x

plugin 18 for x and multiply

4(18) = 72
