The length and breadth of a rectangle are 80cm and 15cm .find its perimeter and area of the rectangle

Answers

Given:

• Length of the rectangle = 80 cm

• Breadth of the rectangle = 15 cm.

To find :

• perimeter and Area of the rectangle .

Solution :

As we know that:

• perimeter of the rectangle = 2 ( l + b)

=> perimeter = 2 ( 80 + 15)

=> perimeter = 2 ( 95 )

=> perimeter = 190 cm .

• Area of the rectangle = l×b

=> Area = (80×15)

=> Area = 1200 cm² .

Hence , the perimeter of the rectangle is 190 cm and Area us 1200 cm².

I hope it will help you.

solve x2 + 4x - 5 = 0 using quadratic formula​

Answers

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

In that equation,

a=1

b=4

c=-5

So put these informations to quadratic formula,

-4+_ √16-4*1*-5 / 2

= -4+_ √16+20 / 2

= -4+_ √36 / 2

= -4+_6 / 2

To calculate this, the answers are

-4+6 / 2 and -4-6 / 2

2 / 2 and -10 / 2

So answers are 1 and -5

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

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

Answers

Answer:

24

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

4.7/15


A.0.875
B.0.46
C.0.7
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

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
