Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.

Your equation should look like:

5h + 20 = 90

Subtract 20 from both sides.

5h = 70

Divide both sides by 5.

h = 14

Gina can rent a surfboard for 14 hours if she has $90.

The ratio of the measure of the acute angle in a right triangle is 1/2 . Find the measures of the two angles
AleksandrR [38]

30° and 60°.

<h3>Further explanation</h3>

We will solve the problem of the measures of angles in the triangle.

Recall this condition:

  • The acute angle ⇒ an angle of less than 90°.
  • The right angle ⇒ an angle of exactly 90°.
  • A right triangle ⇒ a triangle in which one angle is a right angle.
  • The interior angles ⇒ the angles inside a triangle.
  • All the interior angles in a triangle , i.e., \boxed{ \ \angle A + \angle B + \angle C = 180^0 \ }

<u>Given that:</u>

The ratio of the measure of the acute angle in a right triangle is ¹/₂.

<u>Question:</u>

Find the measures of the two angles.

<u>The Process:</u>

We call it the triangle ABC. An interior angle inside is a right angle, e.g., ∠A = 90°.

From the ratio of two other acute angles, i.e., 1: 2, we call it ∠B = x and ∠C = 2x.

Let's arrange the three angles in ABC triangle as follows:

\boxed{ \ 90^0 + x + 2x = 180^0 \ }

Both sides subtracted by 90°.

\boxed{ \ x + 2x = 180^0 - 90^0 \ }

\boxed{ \ 3x = 90^0 \ }

Both sides divided by 3.

We get \boxed{ \ x = 30^0 \ }

We substitute the value of x back into B and C.

\boxed{\boxed{ \ \angle B = x\ } \rightarrow \boxed{ \ \angle B = 30^0 \ }} \\\boxed{\boxed{ \ \angle C = 2x\ } \rightarrow \boxed{ \ \angle C = 60^0 \ }}

We have succeeded in getting the measures of the two angles.

Erik buys carrots and dip for a class snack. The carrots are $3.80, and the dip is$2.60. Erik has a coupon for 5% off his grocer
Leya [2.2K]
3.80+2.60=6.40$ money that erik need to pay
6.40$ x .05=.32 (.05 represent the 5% coupon)
6.40$ - .32=6.08subtract the percent of the coupon to find the total bill of erik
20$ - 6.08=13.92$ subtract the money that erik needs to the 20$ 
13.92$ would be the change that erik receive back
