Becky is working on a weekly budget. She earns $385 per week. Becky spends $200 per week on rent and utilities plus $57 on food. After paying for rent, utilities, and food, Becky deposits 3/4 of the amount left over into a savings account. She spends the rest on entertainment. How much money does she spend on entertainment?

Answers

Answer:

$32

Step-by-step explanation:

200 + 57 = 257.

385 - 257 = 128

128 x 3/4 = 96 (deposited)

128 - 96 = 32

Becky spends $32 on entertainment

what is the perimeter of figure B ?

Answers

Answer:

35 for perimeter of b

122.5 for perimeter of a

Step-by-step explanation:

To find the perimeter, you add all of the values of the outside of the shape together. Since 12+9+9+5 = 35, the answer is 35.

Okay, so what you have to do is set up a proportion for a to b. To do that, you have to have a fraction where a is the numerator and b is the denominator. 7/2 equals x/35. Then cross multiply

7*35 = 2x

x = 122.5 :)

Answer:

The perimeter is 35.

Step-by-step explanation:

To find perimeter, add all the sides together.

9 + 9 + 5 + 12 = 35

The perimeter is 35.

George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.

Answers

Complete question − How many kilometres did they travel by bus and by bicycle.

Answer:George and carmen traveled by bus in 135km and by bikein 215km

Step-by-step explanation:

Total Miles traveled  =   350 miles  

Let Number of kilometres they traveled with bus  = x

and Let Number of kilometres they traveled with bike = x + 80

so that the total distance traveled with bus and bike be expressed as

x + x + 80 =   350 miles  

2x + 80 =   350 miles  

2x =   350 − 80

2x =270

x=135

George and Carmen traveled by bus in 135km  

and by bicycle=x + 80 = 135 km + 80 =215km

Thanks and please shows steps. I will vote best answer and helpful and do more.

Answers

Step-by-step explanation:

tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)

 

                      = (sin2B + cos2B)/[(cosB)(sinB)]

 

                       = 1/[(cosB)(sinB)]

 

                        = (1/cosB)(1/sinB)

 

                        = (secB)(cscB)

The area of the living room carpet was s 262.5 square feet. If the width of the room is 21 feet, then what is the length.


Please help, I’m taking an online test, I need it, quick. :)

(15 points!)

Answers

The length would be 12.5 feet.

A rectangle’s area is calculated with the formula:

A = L * W

To find the length, all we have to do is divide the area (A) by the width (W).

We get the equation:

262.5/21 = L

262.5/21 = 12

L = 12

Answers

Answer: 423.11 m^2


Step by step explanation:

Area of a circle formula pi*r^2

First solve the area of the big circle

3.14*21^2=1384.74 m^2

Now find the are of the smaller circle

r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2

Now we can minus the small area off the big area to get the shaded area.

1384.74-961.63=423.11 m^2

So the area of the shaded region is 423.11 m^2

Calculate the geometric mean of 12 and 20

Answers

Answer:

The Geometric mean of two numbers is the square root of their product.

Given numbers are 12,20.

Geometric mean = √(12*20)

= √240.

= 15.49.

= 15.5.

The geometric mean of 12 and 20 is 4√15.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 3 + 3x + 4y = 7 is an expression.

We have,

The geometric mean of a and b is √(ab).

Now,

a = 12 and b = 20

so,

The geometric mean of 12 and 20.

= √(12 x 20)

= √240

= 4√15

Thus,

The geometric mean of 12 and 20 is 4√15.
