Mark walked 12 1/2 miles in 5 hours. How many miles did Mark walk in 1 hour?
the answe is it is 2.5 or 2 1/2 as he said but in conclusion answe 2 1/2 or 2 and 1 half
Distance can be defined as how far a person or an object can go or cover.
The number of miles Mark walked in 1 hour is [tex]2\frac{1}{2}[/tex] miles
From the question,
In 5 hours, Mark walked a distance of 12 1/2 miles.
Hence,
5 hours = [tex]12\frac{1}{2}[/tex] miles
1 hour = ?
Cross Multiply
1 hour x [tex]12\frac{1}{2}[/tex] miles / 5 hours
= [tex]2\frac{1}{2}[/tex] miles
The number of miles Mark walked in 1 hour is [tex]2\frac{1}{2}[/tex] miles

Step-by-step explanation:
A ball is dropped from a height of 100 cm. The rebound heights to the nearest centimeter are 60, 36, 22, .... What is the total distance the ball will travel both up an down?
Answer:
400 cm
Step-by-step explanation:
Given that:
Initial height at which ball was dropped = 100m
Rebound heights to the nearest cm = 60, 36, 22...
First we find the rebound percentage x;
x% * 100m = 60
100x % = 60
x = 60%
Hemce, we need to calculate the rebound velocities which aren't given:
0.6 * 22 = 13.2 = 13cm
0.6 * 13 = 7.8 = 8cm
0.6 * 8 = 4.8 = 5cm
0.6 * 5 = 3cm
0. 6 * 3 = 1.8 = 2 cm
0.6 * 2 = 1.2 = 1cm
The total distance the ball travels UP and DOWN :
(100 + 2(60) + 2(36) + 2(22) + 2(13) + 2(8) + 2(5) + 2(3) + 2(2) + 2(1))
= 400 cm
A national standard requires that public bridges over feet in length must be inspected and rated every 2 years. The rating scale ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabilistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers forecast that % of all major bridges in that city will have ratings of 4 or below. Complete parts a and b. a. Use the forecast to find the probability that in a random sample of major bridges in the city, at least 3 will have an inspection rating of 4 or below in 2020. P(x3) nothing (Round to five decimal places as needed.)
Answer:
The answer is below
Step-by-step explanation:
A national standard requires that public bridges over 20 feet in length must be inspected and rated every 2 years. The rating scale ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabilistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers forecast that 4%of all major bridges in that city will have ratings of 4 or below.
a. Use the forecast to find the probability that in a random sample of major bridges in the city, at least 3 will have an inspection rating of 4 or below in 2020.
Answer:
This problem is a probability binomial distribution and it can be solved using the formula:
[tex]P(X=x)=C(n,x)p^xq^{n-x}\\\\q=1-p,C(n,x)=\frac{n!}{x!(n-x)!}[/tex]
Hence the solution to the problem is given as:
P(x ≥ 3) = 1 - P(x < 3) = 1 - [ P(x=0) + P(x=1) + P(x = 2)]
Given that p = 4% = 0.04, q = 1 - p = 1 - 0.04 = 0.96, n = 10. Hence:
[tex]P(x=0)=C(10,0)*0.04^{0}*(0.96)^{10-0}=0.6648\\\\P(x=1)=C(10,1)*0.04^{1}*(0.96)^{10-1}=0.277\\\\P(x=2)=C(10,2)*0.04^{2}*(0.96)^{10-2}=0.0519\\\\P(x\geq 3)=1-[0.6648+0.277+0.0519]=0.0063[/tex]

Step-by-step explanation:
[tex]A=\frac{1}{2} ap[/tex]
because you want a, divide both sides by p
[tex]\frac{A}{p} =\frac{1}{2} a[/tex]
then, because the reciprocal of 1/2 is 2, multiply both sides by 2

Step-by-step explanation:
The perimeter of a rectangular garden is 40 it. The length is 2 ft more than the width. Find the length and the width of the garden.
Answer: Length = 11
Width = 9
Step-by-step explanation:
Let x represent the unknown length.
Let x - 2 represent the unknown width.
The perimeter is equal to 2 times x + (x -2)
Equation:
2 (x + (x - 2)) = 40
x + (x - 2) = 40/2
x + x - 2 = 20
2x - 2 = 20
2x -2 + 2 = 20 + 2
The length is: 2x = 22 -> x = 22/2 -> x = 11
The width is: x - 2 = 9
