Last year Sandy earned

$1,978 per month. If she
worked for 11 months,
about how much did Sandy
earn last year?

Answers

21,758 is the answer

Salary earned by Sandy last year = $21758.

What is multiplication?

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

Salary of Sandy per month = $1978

Salary earned by Sandy in 11 months = 11 × $1978

                                                              = $21758

Hence, $21758 is the salary earned by Sandy last year.

In a park for 6 people the ticket cost $39. How many dollar does it cost for 9 people

Answers

$ 58.50

Step-by-step explanation:

because 39 Divided by 6 is 6.5 and 6.5 × 9 it's 58 50

•ANSWER•
$58.50

•EXPLANATION•
The first thing you have to do is divide 39 by 6 to see how much it would cost for 1 person. For 1 person it cost $6.50 then you multiply by 9 because you are trying to figure out how much it cost for 9 people not 1. You will get $58.50.

How much greater is the perimeter of a triangular field with sides that measure 92 yards, 83 yards, and 99 yards than the perimeter of a triangular field with sides that measure 61 yards, 38 yards, and 83 yards?

Answers

Answer:

92 yards

Step-by-step explanation:

Perimeter of a triangle = a + b + c

Field 1 :

Perimeter = (92 + 83 + 99) yards = 274 yards

Field 2:

Perimeter = (61 + 38 + 83) yards = 182 yards

Perimeter difference :

Field 1 - Field 2

(274 - 182) yards

= 92 yards

In this activity, you will find the valine of a composite shape by decomposing it into simpler shapes such as cubes and rectangular prisms. the figure shows the dimension of a writing desk. Complete the steps below to find its volume.

Answers

Answer:

you may recall that the term area tells us something about the number of squares inside a two-dimensional shape.

Step-by-step explanation:

Answer:

Part A

The given shape can be split into three rectangular prisms.

Part B

There are two ways of breaking this shape into three rectangular prisms.

Part C

small rectangle 18 x 26 x 36.5

large rectangle 6.5 x 26 x 74.5

Part D

The length, width, and height of the small prism is 18 inches, 26 inches, and  36.5 inches so the volume is 17,082 cu in.

The length, width, and height of the small prism is 6.5 inches, 26 inches, and  74.5 inches so the volume is 12,590 cu in.

PART E

12,590 + 14,040 + 14,040 = 40,670.5 cu in.

The volume of the desk is the same for both options: 40,670.5 cubic inches. No matter how I divide the composite shape, the resulting volume is the same.

True or False?
k = 2 is a solution to the inequality 8k+ 4 > 18.

Answers

Answer:

True

Step-by-step explanation:

If k = 2, then we plug in 2 for every instance there is a k. So...

8k + 4 > 18

Will turn into...

8(2) + 4 > 18

Then solve using PEMDAS (or whatever you were taught. Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.)

16 + 4 > 18

20 > 18

Since 20 is greater than 18, 2 can be a solution for this inequality.

Combine like terms and simplify
