The measure of an angle is 14.2°. What is the measure of its complementary angle

2 answers:

7 0

Complementary angles are the angles whose sum makes 90 degrees. According to the question, the other angle is 14.2 degrees more than the complementary angle. Therefore, 14.2° will be added to the other angle.

Answer:

75.8º

Step-by-step explanation:

The sum of complimentary angles is 90º

c + 14.2 = 90

Subtract 14.2 from both sides

c = 90 - 14.2

c = 75.8º

Tully draws four 10 - sticks and less than ten circles to make a number. Write the numbers Tully could make

ruslelena [56]

The numbers Tully can make are 41, 42, 43, 44, 45, 46, 47, 48 and 49

<em><u>Solution:</u></em>

Given that Tully draws 4 sticks , each one with value 10

This means that the numbers will be of the set of four tens: 4(10) = 40

Also given that less than ten circles to make a number

We assume that the circles have each value of 1 unit

For circle, Therefore the possible units are: 1, 2, 3, 4, 5, 6, 7, 8, 9

<em><u>Combining together sticks and circles, the possible numbers are given as follows:</u></em>

sticks + circle :

$4(10) + 1 = 41\\\\4(10) + 2 = 42\\\\4(10) + 3 = 43\\\\4(10) + 4 = 44\\\\4(10) + 5 = 45\\\\4(10) + 6 = 46\\\\4(10) + 7 = 47\\\\4(10) + 8 = 48\\\\4(10) + 9 = 49\\\\$

Therefore, the numbers Tully can make are 41, 42, 43, 44, 45, 46, 47, 48 and 49

Hello, can anyone help me im stuck

Answer:

124.5

Step-by-step explanation:

We need to use two different area formulas to get our final answer.

We need the area formula for the triangle = (h*b) / 2; h = height, b = base.

We also need the area for the circle = $\pi r^2$ . r is radius, we will replace pi with 3.14 per instructions.

To start off, let's do the circle. A = 3.14*r^2. r is given to us, r is 8.

So, just plug this into a calculator:

$3.14(8^2)=200.96$

This would be the area of the circle if it was full, however, we only have half of the circle, so we will divide the area in half to get our final circle area, which is 100.48 ft.

Now, for the triangle. Our height is the radius of the circle, which is 8. And our base is 6 feet. Use the formula to get the area for the triangle.

A = 8*6 / 2 = 24

The area of the triangle is 24 feet. Now, we will combine the triangle area and circle area to get our final answer.

100.48 + 24 = 124.48

Round to the nearest hundredth and you get: 124.5 ft^2

Scenario: Kevin is baking cupcakes for a fundraiser at his school. Yesterday, he prepared 30 cupcakes in 45 minutes. Today, he p

attashe74 [19]

a) As the constants are equal, the situation represents a proportional relationship.

b) The constant of 2/3 cupcakes per minute means that in a minute, 2/3 of a cupcake is made.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the constants for each situation are:

k = 30/45 = (30/15)/(45/15) = 2/3 = 20/30.

Since the constants are equal, the situation represents a proportional relationship.

The constant of 2/3 cupcakes per minute means that in a minute, 2/3 of a cupcake is made.
