A rectangular prism has a surface area of 8 square feet. A similar rectangular prism has a surface area of 200 square feet. How many times larger are the dimensions of the larger prism?
5
10
25
625
The number of times larger the dimensions of the larger prism with surface area of 200 ft² to the smaller prism of 8 ft² is 25 times.
Surface area of a rectangular prismThe surface area of a rectangular prism is as follows;
surface area = lwh
where
l = lengthw = widthh = heightTherefore,
surface area of the first prism = 8 ft²
surface area of the second prism = 200 ft²
Therefore, the number of times larger the dimensions of the larger prism with surface area of 200 ft² to the smaller prism of 8 ft² is as follows;
200 / 8 = 25

Answer:
Probability in Maths:-
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.
Formula for Probability:-
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.
Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes
Probability refers to a possibility that deals with the occurrence of random events also can be state as all the events occurring need to be 1.

Step-by-step explanation:
200 miles in 4 hours.
In this situation, in 4 hours, the vehicle has driven a distance of 200 miles.
To determine the distance in one hour, divide the miles by the hour.
200 ÷ 4 = 50.
The vehicle drives at a constant rate of 50 miles per hour.
Emily has 4 1/2 cups of chocolate chips. Her cookie recipe requires 3/4 cup of chocolate chips. How many batches of cookies can Emily make?
Answer:
There are 6 batches of chocolate chip cookies that can be made.
Step-by-step explanation:
First, turn 4 1/2 cups into an improper fraction with a denominator of 4 (which is 18/4). Then, do 18/4 divided by 3/4 (or 18/4 times 4/3 and both 4s cancel). The result is 18/3 or 6 because 3 times 6 equals 18.

Answer: (c)
Step-by-step explanation:
Given
The sticker price is $40,000
The option price is $6000
Destination fees are $800
The base sticker price is 90% of the price i.e.
[tex]\Rightarrow 90\%\times 40,000\\\Rightarrow 0.9\times 40,000\\\Rightarrow \$36,000[/tex]
The option price is 80% of included options i.e.
[tex]\Rightarrow 80\%\times 6000\\\Rightarrow 0.8\times 6000\\\Rightarrow \$4800[/tex]
Dealers cost is given by the sum of three costs
[tex]\Rightarrow 36000+4800+800\\\Rightarrow \$41,600[/tex]
Thus, option c is correct.

Convert 49° Celsius to degrees Fahrenheit using the following formula: F = {C+32 O A. 506.5°F OB. 196.2°F C. 94.6°F OD. 2237°F O E. 120.2°F
Answer:
Step-by-step explanation:
F = 9/5C + 32
Putting value
9/5(49) + 32
88.2 + 32
= 120.2°F
Option E is the correct answer
The Celsius temperature 49 in Fahrenheit is 120 F.
To convert Celsius to Fahrenheit, you can use the formula:
F = (C × 9/5) + 32
Let's calculate the conversion using the given Celsius value:
C = Celsius temperature
F = (C × 9/5) + 32
F= (49 x 9/5)+ 32
F= 88.2 + 32
F = 120.2 F
Thus, Celsius temperature 49 in Fahrenheit is 120 F.

pedro's car averaged 957 miles on its 29-gallon tank of gas. If pedro runs out of gas and a mechanical comes to his rescue with 2 3/4 gallons of gas, determine how far his car can go. Round to the nearest
Answer:
His car can go 90.75 miles.
Step-by-step explanation:
We solve this question using proportions.
Pedro's car averaged 957 miles on its 29-gallon tank of gas.
This means that per gallon, his car can go:
957/29 = 33 miles.
2 3/4 gallons of gas
[tex]2 + \frac{3}{4} = 2 + 0.75 = 2.75[/tex] gallons.
Determine how far his car can go.
For each gallon, the car goes 33 miles. He has 2.75 gallons, so his car can go 33*2.75 = 90.75.
His car can go 90.75 miles.
