A company is expanding its building area from 11,000 square feet to 14,740 square feet. What is the percentage increase of the a
svlad2 [7]

Option D

The percentage increase of the area  of the building space is 34 %

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

A company is expanding its building area from 11,000 square feet to 14,740 square feet

To find: Percentage Increase

<em><u>The percent increase is given by formula:</u></em>

\text{Percent increase } = \frac{\text{Final value - Initial value}}{\text{Initial value}} \times 100

From given,

Initial value = 11000

Final value = 14740

<em><u>Substituting we get,</u></em>

Percent\ Increase = \frac{14740-11000}{11000} \times 100\\\\Percent\ Increase = \frac{3740}{110}\\\\Percent\ Increase = 34

Thus percentage increase of the area  of the building space is 34 %

22. a. In 1990, Nadezhda Ryashkina set the record for the 10,000 m race-walking event. She finished this race in 41 minutes 56.2
iVinArrow [24]

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.

<h3>What was Ryashkina's average walking rate?​</h3>

Rate or speed is expressed as distance walked or traveled per unit time.

R = s/t

Given the data in the question;

  • Distance covered s = 10,000m
  • Time elapsed t = 41 minutes 56.23 seconds
  • Rate r = ?

First convert 41 minutes to seconds.

⇒ 41min = ( 41 × 60 )s = 2460sec

Now, Elapsed time t = 2460s + 56.23s = 2516.23 second

Next, we determine the rate.

R = s / t

R = 10000m / 2516.23 s

R = 3.97m/s

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.

I need help with solving the value of x. Then finding the measure of the base angle.
romanna [79]

Answers:

x = -3

base angle = 49 degrees

============================================

Work Shown:

The missing angle is (2x+55) degrees since the base angles are congruent.

Add up the three angles and set the sum equal to 180. Solve for x.

(82)+(2x+55)+(2x+55) = 180

4x+192 = 180

4x = 180-192

4x = -12

x = -12/4

x = -3

Use this x value to find the base angle

B = base angle

B = 2x+55

B = 2*(-3)+55

B = -6+55

B = 49 degrees
