Answers

Answer:

Step-by-step explanation:

The smaller rectangle has a perimeter of 200 meters. Let's say that the smaller rectangle has length 60 and width 40. This would give it a perimeter of 200, since 2*(60+40) = 200.

If these are the length and width of the smaller one, we can multiply each by 5/4 to get the length and width of the larger one.

length of larger rectangle = 60*5/4 = 75

width of larger rectangle = 40*5/4 = 50

These dimensions would give a perimeter of 250, since 2*(50 + 75) = 250.

It is worth noticing that 250 is equal to 200 * 5/4. In the future, you can simply multiply perimeter by the ratio instead of going through all these steps.

Answer:

y-1=5(x+6)

Step-by-step explanation:

Point slope:

(y-y1)=slope(x-x1)

y-1=5(x+6)

Hope this helps!

Answer:

y - 1 = 5(x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 5 and (a, b) = (- 6, 1), then

y = 1 = 5(x - (- 6) ), that is

y - 1 = 5(x + 6)

4. You have $40 in your wallet, but you do not want to spend all of it. You want to have at least some money left. You find a shirt for $5 and buy it. What is the amount of money (m) you have left to spend?
A. m + 5 ≤ 40
B. m + 5 40

Answers

It’s b because m represents the amount of money left over and m plus five equals the original amount and after that if you subtract 5 from 40 it gives u the answer to m which is the answer

The amount of money (m) you have left to spend is A) m + 5 ≤ 40.

The answer is A. m + 5 ≤ 40.

The amount of money you have left to spend is represented by m. After buying the shirt, you have m - 5 dollars left. Since you want to have at least some money left, m - 5 ≤ 40.

Option B is incorrect because it states that m + 5 is greater than or equal to 40. This would mean that you have more than 40 dollars left after buying the shirt, which is not possible.

Here is a table that shows the different values of m and m - 5:

As you can see, the value of m - 5 is always less than or equal to 40. This is because m is always less than or equal to 45.

Therefore, the correct answer is A. m + 5 ≤ 40.

Evaluate the following expression. (-5+ 7 x 1) - 9 x 5​

Answers

Answer:

-43

Step-by-step explanation:

(-5+7*1)-9*5  ---> * is muliplication sign

(-5+7)-45 --->multiplications first

(2)-45---> next the parantheses

-43 ---> the answer!!!

Answer:   -43

==================================================

Explanation:

We'll use PEMDAS here.

Focus on the stuff in the parenthesis first. We multiply 7 and 1 to get 7*1 = 7

Then we add on -5 getting -5+7 = 2

The stuff in the parenthesis turns into 2

We go from this

(-5+7*1) - 9*5

to this

2 - 9*5

From here we multiply 9 and 5 to get 45, then subtract like so

2-45 = -43

-----------------------------

So here's the step by step picture

(-5 + 7*1) - 9*5

(-5 + 7) - 9*5

(2) - 9*5

2 - 9*5

2 - 45

-43

The unit price (rate) per 1 gallon of gas is $3.00. The constant of proportionality is $3.00. Using the unit rate, how much will 15 gallons of gas cost?

a) $3.00
b) $21.00
c) $45.00
d) $90.00

Answers

Hi I’m pretty sure the answer is c.

Since 1 gallon is $3 you know that if you multiply 1 by 15 and ALSO multiply $3 by 15 you will have your answer.

15x1 gallon = 15 gallons
15x$3 = $45

15 gallons = $45

Three experts gave opinions on how long a task will take to finish. The estimates were 29, 10, and 12 days (in no particular order). What is PERT estimate - ROUNDED

Answers

Answer:

15

Step-by-step explanation:

PERT estimate is a measuring strategy that is based on a weighted average. It is used in measuring the uncertainty and risk via three estimates to determine an estimated likelihood for a project's cost or period of completion.

The formula is (O + 4M + P) ÷ 6

Where P is the most pessimistic = 29

M is the most likely = 12

O is the most optimistic = 10

Hence we have (10 + [4*12]+ 29) ÷ 6

= (10 + 48 + 29) ÷ 6

= 87÷6 = 14.5 ≈ 15

Rounded figure is equal to 15.

Hence the final answer to the question is 15

First let us convert them to fraction;

5^-2 = 1/5^2

5^-2 = 1/25

Also;

5^-1 = 1/5^1

5^-2 = 1/5

Multiplying both fractions;

[tex](5^{-2})(5^{-1})[/tex] = 1/25 * 1/5

[tex](5^{-2})(5^{-1})[/tex] = 1/125

[tex](5^{-2})(5^{-1})[/tex] = 1/5^3

Step-by-step explanation:

At a recent election a total of 93648 votes were cast for the 4 candidates, the winner exceeding his opponents by 25627, 10681 and 55924 votes respectively . How many votes cast for each candidate?

Answers

Answer:

The number of votes cast for each candidate are as follows:

Candidate a = 46470

Candidate b = 20843

Candidate c = 35789

Candidate d = -9454

Step-by-step explanation:

Let A, B, C and D represents the number of votes for a (winner), b, c and d candidates. Therefore, we have:

A + B + C + D = 93648 ................. (1)

Also, we have:

A - B = 25627

B = A - 25627 ........ (2)

A - C = 10681

C = A - 10681 ............. (3)

A - D = 55924

D = A - 55924............. (4)

Substituting equations (2), (3) and (4) into (1) and solve for A, we have:

A + A - 25627 + A - 10681 + A - 55924 = 93648

4A = 93648 + 25627 + 10681 + 55924

4A = 185880

A = 185880 / 4

A = 46470

Substituting A = 46470 into each of equations (2), (3) and (4), we have:

B = 46470 - 25627 = 20843

C = 46470 - 10681 = 35789

D = 46470 - 55924 = -9454

Therefore, the number of votes cast for each candidate are as follows:

Candidate a = 46470

Candidate b = 20843

Candidate c = 35789

Candidate d = -9454

Additional Note:

It should be noted that Candidate d has negative votes of -9454. This is possible because a negative vote is voting system that gives votes the opportunity to indicate dislike for a candidate, without increasing the votes of other candidates, and the number of dislikes will be the number of votes that will be deducted from the votes of the candidates. Therefore, a candidate can have negative votes cast if he gets only dislikes or more dislikes than votes.

Mr. King will pay for the floor mats after taxes?

Answers

Answer:

$155.88

Step-by-step explanation:

We can set up an expression like this to find the final price of the floor mats:

([cost of floor mats]*[sales tax])+[cost of floor mats]

= (145*0.075)+145

= 10.875+145

Tim plans to spend 40 hours on exercise training to eam a private trainer llcense. He has saved $2,000 for training. Tim
would like to determine the most he can afford to pay per hour for training.
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the
Inequality.

Answers

Answer:

The answer is for 50$ per hour Tim will be able to complete the training for private license.

Step-by-step explanation:

You divide 2,000 by 40.

= 2,000/40 which equals 50. so, Tim can spend $50 on training if he plans to do 40 hours.

This situation can be easily solved since Tim only wants to know the amount he needs to pay for an hour of training.

for 40 hours = 2,000$

for 1 hour = 2,000/40

               = 50$ per hour

So for 50$ per hour Tim will be able to spend 40 hours on training.
