Answer: The area of the top of the walkway is 1,050 square feet
Step-by-step explanation:
Hi, to answer this question we simply have to apply the next formula:
Area of a rectangle: width x length (of the base)
Replacing with the values given and solving for A:
A = 25 feet x 42 feet = 1,050 square feet
In conclusion, the area of the top of the walkway is 1,050 square feet

A) Variance = 10.24
B) Standard Deviation = 3.2
One of the measurements of dispersion is the standard deviation, which is exclusively used for quantitative data. It aids in determining if the data's mean is a suitable measurement to reflect the core value.

∑f = 127
∑fd = -136
∑fd² = 552
Standard Deviation = 
√4.35 - √1.15
Standard Deviation = 3.2
(SD)² = (3.2)² = 10.24
Variance = 10.24

Answer:
5years
Step-by-step explanation:
Interest=Principal*Rate*Time/100 which is
I=P*R*T/100
- 1500=6000*5*T/100
- 1500=30000/100*T
- 1500=300T
- 1500/300=T
- 5=T
Therefore T which is Time=5 years.

The amount of dollars that Mr. Levant would exchange for 100 pesos on his return is <u>$9</u>.
<h3>What is an exchange rate?</h3>
An exchange rate is a rate that is used to convert one nation's currency to another.
The exchange rate is based on the purchasing power of each nation's currency.
<h3>Data and Calculations:</h3>
Dollars before traveling to Mexico = $270
Value of Mexican pesos received for $270 = 3,000 pesos
Exchange rate = $1 = 11.11 pesos (3,000/$270)
Amount of pesos left after the trip = 100 pesos
Value of 100 pesos in dollars = <u>$9</u> (100/$11.11)
Thus, the amount of dollars that Mr. Levant would exchange for 100 pesos on his return is <u>$9</u>.

Answer:
B. (-r, 0)
Step-by-step explanation:
W is on the x axis, so the y coordinate is 0.
It is also r away from the origin, so the x coordinate is -r
