Answer:

D)

Step-by-step explanation:

The hypotenuse is a bit longer than that of the longer side.

Say, 17 miles.

15+8+17

23+17

40

40 is equal to D.

Hope this helped!

You'd have to find the length of C using the Pythagorean theorem.
So 15^2 + 8^2 = c^2
64 + 225 = c^2
289 = c^2
find the square root of each side
17 = c
You then add each side 15 + 8 + 17 which equals to 40 so 40 miles total !!

Answer:

50 dog walks in 10 hours (1 month)

Step-by-step explanation:

If Darius made 10 dog walks in 2 hours,   then in one month, it took Darius  10 hours to make 50 dog walks.

Using the first formula,    2 hours ÷ 1/5 = 10, then

                                        10 hours (in one month)  ÷  1/5 = 50 dog walks.

Hope this helps!

In problem #1,  rewrite the problem using the reciprocal (the inverse) of 1/5 to 5/1  and change the division sign to multiplication.  Do this for both equations.

Problem 1.)   Write 2 ÷ 1/5  =  2 x 5/1 = 10.

Problem 2.)   10  ÷ 1/5 = 10 x 5/1 =50.

Problem 3.)  Just explain that in one month, it took Darius 10 hours to walk 50 dog walks using the formula from problem 2 above. Good Luck!

The adult height of a male is about 1.19 times his height at age 12. The adult height of a female is about 1.07 times her height at age 12. Predict how tall is Miguel and Ramona will be as adults if Miguel is 1.5 m and Ramona is 1.6 m. Predict how tall you will be.

Pls help me I don't understand how to get how yall I will be and I think I did the first part right but not too sure.

Answers

If you are 12 years old, just measure your own height, then multiply your height by 1.19 if you’re a male, or 1.07 if you’re a female.

The height of Miguel as an adult is 1.785 m.

The height of Ramona as an adult is 1.712 m.

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: 2 + 3x + 4y = 7 is an expression.

We have,

The adult height of a male is about 1.19 times his height at age 12.

The adult height of a female is about 1.07 times her height at age 12.

Now,

Miguel:

Height at the age of 12 = 1.5 m

The height when he is an adult.

= 1.19 x 1.5

= 1.785 m

Ramona:

Height at the age of 12 = 1.6 m

The height when she is an adult.

= 1.07 x 1.6

= 1.712 m

Thus,

The height of Miguel and Ramona as adults are 1.785 m and 1.712 m.
