Answers

Answer 1

Answer:

10:7

Step-by-step explanation:

ratios are simply just like fractions!

this ratio (40:28) can be re-written as 40/28

now, you can simplify this to its lowest terms

40/28=20/14=10/7

first in those steps i re wrote the question, then divided by two, then divided by two again !

so, 40:28=10:7

--------------------------------

you can even check this by cross multiplying, since ratios are fractions

[tex]\frac{40}{28} =\frac{10}{7}[/tex]

40x7=28x10

280=280

they are equivalent which means our ratio is correct :)

hope this helped <333

A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).

In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.

The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”

Answer: -30

Step-by-step explanation:

[tex] {(8 - 10)}^{2} - 30 \div 5 \times 6 + 2[/tex]

BODMAS

let's first solve the bracket:

[tex] = {( - 2)}^{2} - 30 \div 5 \times 6 + 2 \\ = 4 - 30 \div 5 \times 6 + 2[/tex]

then let's divide:

[tex] = 4 - (30 \div 5) \times 6 + 2 \\ = 4 - 6 \times 6 + 2[/tex]

then let's multiply:

[tex] = 4 - (6 \times 6) + 2 \\ = 4 - 36 + 2[/tex]

simplify:

[tex] = - 30[/tex]

Solve the equation for y

6=4x+9y

Answers

Answer:

y= [tex]-\frac{4x}{9}[/tex] + [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

6=4x+9y

First swap sides so that all variables are on the left side.

4x+9y=6

Subtract 4x from both sides.

9y=6-4x

Divide both sides by 9, this undoes the multiplication.

y=[tex]\frac{6-4x}{9}[/tex]

Divide 6-4x by 9.

y= [tex]-\frac{4x}{9}[/tex] + [tex]\frac{2}{3}[/tex]

Tamara bought three skirts at one price and 2 skirts priced $3 below the others. The total cost was $118.95. Find
the price of the skirts.

Answers

Answer:

The three skirts each cost $24.99

The two skirts priced $3 below the others cost $21.99

Step-by-step explanation:

Let [tex]a[/tex] represent the amount of money the "three skirts at one price" costs.

Let [tex]b[/tex] represent the amount of money the "2 skirts priced $3 below the others" costs.

From there, we can form the system of equations and solve:

[tex]3a+2b=118.95\\a-3=b\\\\3a+2(a-3)=118.95\\3a+2a-6=118.95\\5a-6=118.95\\5a=124.95\\a=24.99\\\\a-3=b\\24.99-3=b\\21.99=b\\b=21.99[/tex]

△ABC has vertices A(2, 2), B(3, 4), and C(5, 2). What are the coordinates of point C of the image of the triangle after a dilation centered at the origin with a scale factor

Answers

Answer:

5,3efye765tygddgydc b Janet right currency

If the value of the scale factor is 2.5 then the coordinates of point C of the image of the triangle after dilation is (12.5, 5).

What is dilation?

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

△ABC has vertices A(2, 2), B(3, 4), and C(5, 2).

Then the coordinates of point C of the image of the triangle after a dilation centered at the origin with a scale factor of 2.5.

Then the dilated point C' will be given as

C' = Scale factor × C

C' = (2.5 × 5, 2.5 × 2)

C' = (12.5, 5)

More about the dilation link is given below.

Sebastian bought snacks for his team's practice. He bought a bag of chips for $2.51
and a 6-pack of juice bottles. The total cost before tax was $12.53. Write and solve an
equation which can be used to determine j, how much each bottle of juice costs?

Answers

Answer:

12.53 = 6j + 2.51

Step-by-step explanation:

Since there are 6 bottles, we would muitply j by 6 to end up with 6j

The price of the bag of chips, $2.51, is already added on to make up the total cost of $12.53

12.53 = 6j + 2.51
