P = perimeter
L = length
W = width
Formula for the perimeter of a rectangle = L + L + W + W or P = 2L + 2W
You know:
P = 110ft
L = W + 5 [length is 5ft greater than the width]
So plug this into the formula:
P = 2L + 2W Substitute/plug in (W + 5) for L
110 = 2(W + 5) + 2W Distribute/multiply 2 into (W + 5)
110 = (2)W + (2)5 + 2W
110 = 2W + 10 + 2W Combine like terms (2W + 2W)
110 = 4W + 10 Subtract 10 on both sides
110 - 10 = 4W + 10 - 10
100 = 4W Divide 4 on both sides to get "W" by itself
[tex]\frac{100}{4}=\frac{4W}{4}[/tex]
25 = W Now that you know the width, plug it into the equation for length
L = W + 5 Plug in 25 for W
L = 25 + 5
L = 30
L = 30 ft
W = 25 ft
PROOF
P = 2L + 2W
110 = 2(30) + 2(25)
110 = 60 + 50
110 = 110

What is the value of 4x 3+4x when x=4
Final answer:
The value of 4x when x=4 is 16, and for proportions like 1:2=4:x, you'd get x=8 by cross multiplying.
Explanation:
The value of 4x when x=4 is simply 4 multiplied by 4, which equals 16. This calculation is a basic algebraic operation, and it should not be confused with more complex problems. For example, if you're trying to solve a proportion like 1:2=4:x, you'd set up a proportion to figure out the value of x. To solve for x you can use the cross multiplication method, resulting in 1x = 8, hence x = 8.
Final answer:
The value of 4x^3 + 4x when x=4 is found by substituting 4 into the expression and simplifying step by step, resulting in a final answer of 272.
Explanation:
When answering a question such as "What is the value of 4x3 + 4x when x=4," we need to substitute the value of x into the expression and simplify.

Sylvia is practicing for her next track meet by running laps and recording her time.For each timed practice run, Sylvia runs a total of 2000 meters.Each lap is exactly 200 meters.If Sylvia has exactly 200 meters left to run, how many laps has she completed?
Sylvia has completed 9 laps.
Step-by-step explanation:
Step 1; Sylvia runs for a total of 2000 meters. Each lap is 200 meters long. To find the number of laps remaining we need to know the total distance, the distance already covered and the distance on each lap. The distance left to run is equal to the total distance to be run - the distance already ran = 2000 - 1800 meters = 200 meters.
Step 2; The number of laps remaining = The distance left to run/distance on each lap.
The number Number of laps remaining = 200 meters/200 meters
The number of laps remaining = 1 lap.
Final answer:
To determine the number of laps a runner has completed when given the remaining distance to run and the length of each lap, multiply the number of laps by the length of one lap. Answer is 9 laps.
Explanation:
To convert the number of track laps to a distance in meters:
First, determine the length of one lap in meters (e.g., 200 meters in this case).Next, multiply the number of laps completed by the length of one lap to find the total distance covered.For Sylvia, if she has 200 meters left to run and each lap is 200 meters, she has completed a total of 9 laps (2000 total meters - 200 meters left = 1800 meters covered; 1800 meters / 200 meters per lap = 9 laps).Juan is waiting for the roller coaster at an amusement park. He has been told there is a 40% chance that he will have to wait more than 15 minutes. Find the probability both as a decimal and as a reduced fraction
Answer:
0.4, 2/5
Step-by-step explanation:
The probability that Juan has to wait more than 15 minutes is 0.4 and the probability that Juan doesn't have to wait for more than 15 minutes is 0.6
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here, there is a 40% chance that he will have to wait more than 15 minutes. Thus the probability of him waiting for more than 15 minutes is 0.4 and the probability that he has to wait less than 15 minutes is 1-0.4=0.6
Hence, P(<15)=0.6 or 3/5 and P(>15) = 0.4 or 2/5 are the probabilites for Juan

Tina wants to run 12 3/5 miles over 7 days she wants to run the same distance each day how far must she run each day
To find out how much Tina needs to run each day, divide the total miles she wants to run by the number of days. The result is that Tina needs to run 1.8 miles each day.
Explanation:To find out how far Tina must run each day, we need to divide the total distance she plans to run by the number of days she plans to run. Tina wants to run 12 3/5 miles over 7 days. As a first step, convert her mixed number to an improper fraction. 12 3/5 is equivalent to 63/5.
Now, to find the distance she must run each day, simply divide 63/5 miles by 7 days. Carrying out this division gives us distance of 9/5 miles per day, or in decimal form, 1.8 miles per day.
So, Tina should run 1.8 miles each day to reach her goal.

The probability that an event will not happen is P(E) = 0.57. Find the probability that the event will happen.
The probability that the event will happen is
answer:
99.43
Step-by-step explanation:
because there is a 0.57 chance something will not happen, we will fill the rest of the equation in with 100 percent subtracted by 0.57 to get 99.43. Therefore, 99.43 is the correct answer.
Final answer:
To find the probability of an event happening when the probability of it not happening is 0.57, subtract 0.57 from 1, resulting in 0.43.
Explanation:
The probability that an event will not happen is given as P(E) = 0.57. To find the probability that the event will happen, we use the formula P(A) + P(~A) = 1, where P(A) is the probability of the event happening and P(~A) is the probability of the event not happening. The probability of the event happening, therefore, is 1 - P(E) = 1 - 0.57 = 0.43.
