Answer 2

Answer: The proportion is 9/w = 25/100

Step-by-step explanation:

Solve by cross multiplying

9 × 100 = 25 × w

900 = 25w . Divide both sides by 25

900/25 = 25w/25

36 = w

It is also possible to use simpler fractions if you remember that 25% is the same as 1/4

9 is 1/4 of w,

9 = w/4 So multiply both sides by 4

4(9) = 4(w/4) . The 4s "cancel" on the right

36 = w

Why does -2.4-(-7)have the same result as -2.4+7? Explain your reasoning.

Answers

Answer:

-2.4-(-7) has the same result as -2+7 because the negative sign and the minus sign cancel each other out. Think of it like this. If you cross the negative sign and the minus sign together, then it makes a plus sign.

Which of the following functions represents the values in the table below?

x 0 2 4 6
f(x) 2 10 66 218

f(x) = -3x - 2x^2

f(x) = x^2/2

f(x) = 2 + x^3

f(x) = 3x - 2

Answers

As you can see, in the table of the first function, f(2) = 18, and in the table of the second function g(2) = 18. Then, for x = 2, f(x) = g(x). and x =2 is the solution of the equation.

Answer: x = 2.

The required function that represents the value in the table is f(x) = 2 + x³. Option C is correct.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Put x = 0 in every given function,
Then that function that gives 2 will be our required function,
So,

f(x) = 2 + x³.
f(0) = 2 + 0³
f(0) = 2

Thus, the required function that represents the value in the table is f(x) = 2 + x³. Option C is correct.

Answer:

c. $156

Step-by-step explanation:

There are two ways to solve this problem. The first is doubling the first cost as 6 is 2(3). The other way is subtracting the previous number in the sequence with the new one. For example 104-78=26. Then add 26 to 130 and you get 156.

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a pay. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.

You'll apply properties of multiplication in the following questions to find the total cost of the fabric.

2. Multiply the amount of fabric by the price per yard to find an expression for the total cost. Show your work.

Answers

1 pair of wings = 3/4 yd. To find the price of one pair of wings, you get 3/4 of $8 which is $6. Mr. Townsend needs 13 wings.
$6/pair x 13 pairs =
$78 for 13 pairs of wings.

13 wings is $78

If each wing is 3/4 a yard and a yard is $8 you do .75x8=$6 so it costs $6 per wing

Then to find how much for 13 wings do 13x6=78
