Find the ratio of 2 1/2 hours to 15 minutes?

Answers

When both the measures are in the same units, then the ratio can be calculated.

1 hour = 60 minutes

⇒ 2 hours = 2 x 60 minutes

= 120 minutes

The ratio of 50 minutes to 2 hours is then:

50 : 120

⇒ 5 : 12

Determine if the ordered pair (-4,3) is a solution of
4x - y = -13
Show ALL your work here

Answers

Answer:

This is NOT a solution

Step-by-step explanation:

If we plug in the coordinates (-4,3) into 4x-y our new equation is 4×-4-3 and if we solve this equation.... 4×-4=-16 and -16-3=-19 which does NOT equal to -13

Simplify: 9 (5x-4) + 4x

Answers

Answer:

49x+36

Step-by-step explanation:

Hey There!

for this question they would like you to simplify the expression using distributive property

To do this the first step is to distribute the 9 in to everything that is in the parenthesis

9x5x=45x

9x4=36

so now we have

45x+36+4x

the next step is to combine like terms

the only like terms in the expression are 45x and 4x so we just add the two together

45x+4x=49x

so now we have 49x+36

In conclusions the simplified version of that expression is 49x+36

The normal price of an e-scooter is £370
In a sale, there is 1 off the normal price of the e-scooter.
b) Work out the price of the e-scooter in the sale.
Write your answer in £.

Answers

Answer:

A) Isaac should get £ 10.75 in change.

B) The price of the e-scooter in the sale is £ 366.3.

Step-by-step explanation:

A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:

(20 x 5) - (17 x 5.25) = X

100 - 89.25 = X

10.75 = X

So Isaac should get £ 10.75 in change.

B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:

370 - (370 x 0.01) = X

370 - 3.7 = X

366.3 = X

Thus, the price of the e-scooter in the sale is £ 366.3.

He earns $25 per hour for training and $15 per hour for data entry support. Steven can work no more
than 40 hours a week. He wants to use linear programming techniques to optimize his income.
Part A
Construct a model to represent the amount of time Steven can spend on data entry and training. Be sure
to define your variables. Sketch a graph of your model.
Part B
While Steven would like to spend most of his time training, the number of hours spent training cannot
exceed twice the number of hours doing data entry support. Steven must spend at least 10 hours each
week on data support. Construct a model to show the constraints. Sketch a graph of your model.
Part C
Find the vertices of the feasible region. Show your work or explain how you found the coordinates.
Part D
What is the maximum possible amount of money Steven can earn in a week given the constraints? Round
to the nearest dollar. Validate your solution to assess the reasonableness of you
Part E
The number of hours Steven worked one week resulted in a gross income of $800. From this, a portion was
withheld for benefits, retirement, and taxes. The total amount withheld from Steven’s check was $264.
The amount withheld for taxes was twice the amount withheld for retirement, and the amount withheld
for benefits was $24 less than the sum of retirement and taxes. Construct a system of equations that can
be used to find the amount of benefits, retirement, and taxes. Be sure to define your variables.
Part F
Solve the system from Part E. Validate your solution to assess the reasonableness of your model.
