the perimeter of a rectangular window is 280cm. if the length of the window is 83cm, what is the width

Answers

Answer 1

Answer:

the width would be 57cm

Step-by-step explanation:

to find the perimeter you have to add up all of the sides so for this one you would multiply 83 by 2 which would give you 166cm and then subtract it by 280cm which would give you 114cm and then you divide 114 by 2 which would give you 57

−a2 − (2a − 7b) + b for a = −2 and b = 3

Answers

Answer:

Step-by-step explanation:

Given

- a² - (2a - 7b) + b ← substitute a = - 2, b = 3 into the expression

= - (- 2)² - (2(- 2) - 7(3)) + 3

= - 4 - (- 4 - 21) + 3

= - 4 - (- 25) + 3

= - 4 + 25 + 3

= 24

Answer: 32

Steps: -(-2)2 - [ 2(-2) - 7(3) ] + 3

• Follow the PEMDAS order of operations

Calculate within parentheses [ 2(-2) - 7(3) ] : -25

= -(-2)2 - (-25) + 3

Multiply and divide (left to right): 4 - (-25) + 3

Add and subtract (left to right): 32

Johnnie runs 4.5 km everyday to stay in shape. It takes him 30 minutes to run his route. What is his average speed per hour?

Answers

Answer:

The average speed is 9 km per hour

Step-by-step explanation:

Average speed = total distance ÷ total time

Let us use this rule to solve the question

∵ Johnnie runs 4.5 km every day

∴ The total distance = 4.5 km

∵ It takes him 30 minutes to run his route

∴ Total time = 30 minutes

→ We need to change the time to hours to find the average speed in km/h

∵ 1 hour = 60 minutes

→ Divide the time by 60 to change it from minutes to hours

∴ Total time = 30/60 = 0.5 hour

∵ Average speed = distance ÷ time

∴ Average speed = 4.5 ÷ 0.5

∴ Average speed = 9 km/h

∴ The average speed is 9 km per hour

Quadratic formula is -b+_ √b^2-4ac / 2a

In that equation,

b=4

c=-5

So put these informations to quadratic formula,

-4+_ √16-4*1*-5 / 2

= -4+_ √16+20 / 2

Mariana wants to attend Texas A&M. One year at Texas A&M costs approximately $28,000. She currently has $7,000 in savings. Mariana has received a one-time grant of $1,000 and an annual academic scholarship for $6,000. She plans to enroll in the work study program that will pay $10,000 annually for part-time work. How much will Mariana need to borrow in student loans in order to attend Texas A&M for 4 years?

Answers

Answer:

$58,000

Step-by-step explanation:

Total money that Mariana will generate:

Savings = $7,000

One-time grant = $1,000

Annual academic scholarship = $6,000

study program = $10,000/year

Study program for 4 years = $40,000

Total = $7,000 + $1,000 + $6,000 + $40,000

Total = $54,000

Total money that Mariana will generate for her 4 years = $54,000

Cost of fee at Texas A&M per year = $28,000

Cost of fee at Texas A&M for 4 years = 4*$28,000 = $112,000

Amount Mariana will have to borrow to attend Texas = $112,000 - $54,000

Amount Mariana will have to borrow to attend Texas = $58,000

Hence Mariana will have to borrow $58,000 in student loan to attend Texas A&M for 4 years

13-14 is over -3-12

So we would get -1 over -15

which simplifies to 1/15

Match each fraction with its equivalent decimal number.

D.0.7

Answers

Answer:

below

Step-by-step explanation:

We can divide all the given fractions to find there decimal equivalents.

7 ÷ 9 = 0.77...

7 ÷ 19 = 0.368421

7 ÷ 8 = 0.875

7 / 15 = 0.466...

Now, we see that these match up;

7.9 -> C or D (It's not specific in whether the 7 repeats so if it does on your end, please choose that option)

7/19 has no equivalent option.

7/8 -> A

7/15 -> B
