Step-by-step explanation:
It is assumed the width of the street is the distance between the opposite buildings.
<em>See the picture attached</em>
<u>It comprises of two parts: </u>
- x and y
<u>Using Pythagorean theorem, lets find the value of x:</u>
- x² + 15² = 17²
- x² = 289 - 225
- x² = 64
- x = 8 m
<u>Same rule for y:</u>
- y² + 8² = 17²
- y² = 289 - 64
- y² = 225
- y = 15 m
<u>The width of the street (road) is:</u>
- 8 m + 15 m = 23 m
Answer:
24
Step-by-step explanation:
there are 6 seats and 3 boys, 3 girls.
First seat can be given to either boy or a girl.
So there are two ways.
If a boy is selected say, then he has to occupy 3rd and 5th only.
There are 2 ways
Now available positions are 2nd, 4th and 6th, in this girls can be arranged in 3! ways = 6
So total number of ways =
Answer:
Step-by-step explanation:
Solve for 'x'.
To solve for 'x', isolate 'x'.
2.8a + 3.2x + 1 = 16.6
Subtract 1 from both sides. {Subtraction property of equality}
2.8a + 3.2x = 16.6 - 1
2.8a + 3.2x = 15.6
Subtract 2.8 a from both sides.
3.2x = 15.6 - 2.8a
Now, divide both sides by 3.2. {Division property of equality}
