Part A: Larry earned $11 walking his neighbors' dogs on Saturday. He earned some extra money on Sunday doing the same thing. Write an expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.

Part B: Larry was able to walk 4 more than twice as many dogs as his friend Kyle. Write an algebraic expression to represent the number of dogs Larry walked compared with Kyle.

Answers

Answer:

Part A: T stands for total money earned and S stands for money earned on Sunday

T = 11 + S

Part B: We know Larry walked AT LEAST twice the amount of dogs than Kyle. So, L standing for Larry and K for Kyle:

L = 2(K)

But, it tells us he walked twice, plus 4 more. So our final equation will be:

L = 2(K) + 4

Step-by-step explanation:

The solution is : y= 11+x, is the expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.

The algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .

What is an expression?

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

Given data

Larry earned $11 walking his neighbors' dogs on Saturday

Also, he earned some extra amount say x dollars on Sundays

let the total earnings be y

Therefore the total earnings can be expressed as

y= 11+x

next part:

It is given in the question that

Larry was able to walk 4 more than twice as many dogs as his friend Kyle have.

Let number of dogs Kyle has = x

and Let Larry walks y miles.

According to the given data

y = 2x + 4

Therefore , the algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .

Hence, The solution is : y= 11+x, is the expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.

And, the algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .

Please please find the area for this polygon!

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.

Mark brainliest please

Answer:

A(b + c) = 112

Step-by-step explanation: For this equation you rewrite the equation with the numbers in place of the variable. This would loook like 8(4 + 10). Next to follow pemdas we do parenthesis first, 4 + 10 = 14. Then you multiply 14 x 8 which is 112. I checked this on a calculator and on paper and both got the same answer.

PLEASE ANSWER!!!!!!
The semicircle below has a diameter of 20. Find the area of the blue region.

Answers

Answer:

Step-by-step explanation:

Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.

If it is helpful, plz give me Brainliest.

Answer:

50pi - 96

Step-by-step explanation:

The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi

The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96

What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given figure,

Height of a triangle is 8 units and the base of the triangle is 6 units.

Here, area = 1/2 ×6×8

= 24 square units

Therefore, option B is the correct answer.
