A playground is rectangular with a length of 78 miles. If the area of the playground is 820 square miles, what is its width? Input your answer as a fraction.

Answers

Answer 1

Answer:

10.5, [tex]10\frac{1}{2}[/tex], or [tex]\frac{21}{2}[/tex]

Step-by-step explanation:

To solve, you can use a variable (x) to represent the width.

The equation for area is A=L×W

So the Area is 820 and the length is 78.

820= 78w

Isolate the variable to solve.

w=10.5128....

If you round, it will be 10.5

10.5 as a fraction is [tex]10\frac{1}{2}[/tex] or [tex]\frac{21}{2}[/tex]

18c) Find the value of x in each case.

Answers

Answer:

x = 22.5°

Step-by-step explanation:

m∠DEA = 2x

DE || AB

m∠EAB = 2x  - by Alternate Interior Angles

Exterior angle = 6x, which equals 2x + 4x

m∠BEA = 4x

Exterior Angle 4x = 2x + 2x

m∠B = 2x

2x + 4x + 2x = 180°

8x = 180°

x = 22.5°

Exterior Angles of a Triangle:

An exterior angle of a triangle is equal to the two REMOTE angles inside the triangle.

In this example, we know that 6x has remote angles of ∠EAB and ∠BEA

We found out that m∠EAB = 2x, so m∠BEA must equal 6x - 2x or 4x

Sum of angles in a Triangle:

The sum of all angles in a triangle is equal to 180°.

In this example, we found all the angles, 2x, 4x, 2x. We added all of those values to equal 8x

Since the sum of all angles = 180°:

8x = 180°

x = 180°/8

x = 22.5°

Lila evaluates the expression using the following steps:(−7.13+63.97)+(−54.8−3.4)−71.1+(−58.2)−129.3Describe the error that Lila made.

Answers

Lila's error was that she added -7.13 to 63.97 to get -71.1

Lila steps are as folows

(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3

In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.

So, the correct expression should be

(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36

So, Lila's error was that she added -7.13 to 63.97 to get -71.1

The probability that Jessica is on time for a given class is 64 percent. If there are 53 classes during the semester, what is the best estimate of the number of times out of 53 that Jessica is on time to class? Round your answer to the nearest integer.
Provide your answer below:

Answers

Using the principle of probability, the estimated number of times Jessica will be on time is 34.

Given the Parameters :

Probability of being on time, p = 64% = 0.64

Total number of classes, n = 53

The best estimate for the number of times Jessica will be on time can be calculated thus :

Mean = np

Hence, we have ;

Mean number of times = (0.64 × 53)

Mean number of times = 33.92

Hence, the estimated number of times Jessica will be on time is 34.

Monday evening, the jar of M & M's© is full. Tuesday, 1 8 of the M & M's are eaten. Wednesday, 1 3 of the M & M's that remained disappeared. Thursday morning, first thing, the jar had 42 M & M's remaining. How many M & M's were in the jar on Monday evening? M & M's

Answers

9514 1404 393

Answer:

  72 M&Ms

Step-by-step explanation:

We understand the problem to say ...

Monday the jar was fullTuesday the jar was 7/8 full (1/8 gone)Wednesday, the jar was (7/8)(2/3) = 7/12 full

That 7/12 full condition corresponds to 42 M&Ms being present.

  42 = 7/12·full

  full = 42(12/7) = 72

There were 72 M&Ms in the jar on Monday evening.

_____

Check

1/8 of 72 = 9 were eaten Tuesday

1/3 of the remaining 63 disappeared on Wednesday. That number is 21, so 63-21 = 42 remained after Wednesday. That is the number seen early Thursday.

There were 72 M & M's in the jar on Monday evening

How to determine the number of M & M's?

Let the initial number be x.

When 1/8 of the M & M were eaten on Tuesday, the remaining proportion is:

Remaining = (1 - 1/8) * x

This gives

Remaining = 7x/8

When 1/3 of the M & M disappeared on Wednesday, the remaining proportion is:

Remaining = (1 - 1/3) * 7x/8

This gives

Remaining = 7x/12

On Thursday, the remaining number of M & M is 42.

This means that:

7x/12 = 42

Divide both sides by 7

x/12 = 6

Multiply both sides by 6

x = 72

Hence, there were 72 M & M's in the jar on Monday evening
