Answer:

See explanation below

Step-by-step explanation:

Margo needs to blow up 119,854 balloons.

120,000 - 146 = 119,854

A marathon is 26 miles.

40 minutes is equivalent to 0.67 hours

(26 miles) / (0.67 hours) = 38.8 mph

Compare the functions shown below: f(x) cosine graph with points at 0, negative 1 and pi over 2, 1 and pi, 3 and 3 pi over 2, 1
Levart [38]

Answer:

  f(x) and h(x) have the same maximum value: 3

Step-by-step explanation:

The maximum value of f(x) is 3 at (π, 3).

The maximum value of g(x) is -2 at (-3, -2).

The maximum value of h(x) is 3 at (0, 3).

Both f(x) and h(x) have the same (greatest) maximum value.

If the relationship is a proportional relationship weite an equation that where x represents the number of adults and y represen
Anestetic [448]

Answer:

y = kx

Step-by-step explanation:

In proportional relationships, the value of one variable increases as the other increases or decreases as the other decreases. It is denoted mathematically as  y ∝ x where x and y are the variables. It follows that

y = kx where k is the proportionality constant.

So in the relationship where x represents the number of adults, and y represents the number of students,

y ∝ x and y = kx

y = kx is the required equation

In a right triangle, the measure of one acute angle is 12 more than twice the measure of the other acute angle. Find the measure
soldi70 [24.7K]

Given:

In a right triangle, the measure of one acute angle is 12 more than twice the measure of the other acute angle.

To find:

The measures of the 2 acute angles of the triangle.

Solution:

Let x be the measure of one acute angle. Then the measure of another acute is (2x+12).

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees. So,

x+(2x+12)+90=180

3x+102=180

3x=180-102

3x=78

Divide both sides by 3.

x=\dfrac{78}{3}

x=26

The measure of one acute angle is 26 degrees. So, the measure of another acute angle is:

2x+12=2(26)+12

2x+12=52+12

2x+12=64

Therefore, the measures of two acute angles are 26° and 64° respectively.
