Bruno leaves Ms. Crabbe's office to return to the gym. As he moves 450 meters in 2 minutes, what is his velocity? Be sure to wri

Anuta_ua [19.1K]

Answer: 225 meters per second

Step-by-step explanation:

Bruno was able to reach 450 meters in just 2 minutes.

His velocity therefore, can be determined by the speed formula which is:

= Distance / Time

= 450 / 2

= 225 meters per second

= 225 m/s

His velocity is 225 m/s.

Ms. Gianco buys a rug that is 10 ¾ feet x 12 ½ feet. What is the area of the rug? Show your thinking with an area model and a mu

NikAS [45]

Answer:

134.375 or 134 3/8 square feet is the area of the rug

Step-by-step explanation:

In this question, we learnt someone bought rug measuring some lengths per sides were asked to help calculate the area of the rug.

Firstly, we can see that the lengths of the two sides differ? We can thus conclude that the rug is rectangular in shape.

Hence, to calculate the area of this rug, what we do is to calculate the area of the rectangle formed by the rug.

Mathematically, the area of the rug would be = l * b

According to the question, we can identify that l = 10.75 feet(3/4 = 0.75) while the b = 12.5 feet(1/2 = 0.5 feet)

Hence the area of the rug A is thus; 10.75 * 12.5 = 134.375 sq. Feet ( 0.375 = 3/8 so we can say 134 3/8 feet)

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.

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