solve each proportion .
120/160=15/y
(fractions)
please help me :(

Answers

Answer 1

Answer:

Y = 20

Step-by-step explanation:

120/ 160 = 15 / y

120/15=8

that means there is a 8 to 1 ratio between them. So now do 160/8 = y

y = 20.

prove it by dividing both fractions to create decimal form. They match, so y = 20.

Actually Welcome to the Concept of the Ratio and Proportions.

Thus the equivalent ratio to 8:5 will be,

24:15 , 40:25 and 16:10

because, here if we reduce by common multiple 24:15 , 40:25 and 16:10 both , we will get as 8:5

so the correct answer is c.) 40:25 and e.) 16:10 b.) 24:15

Gamestop charges only $7 per used video game. Gamefly charges a one time fee of $16 plus an additional $3 per used video game. Write and solve an equation to find when the cost of buying used video games from both companies below will be the same.

Answers

Answer:

The cost of buying used video games from both companies will the same at the 4th video game.

Step-by-step explanation:

Gamestop equation: 7x

Gamefly equation: 3x + 16

7x = 3x + 16

Subtract 3x from both sides;

4x = 16

Divide both sides by 4x

x = 4

Amber bought three 8 pound bags of dog food at $2.25 per pound, two 4 pound bags of cat food at $1.75 per pound, and three 1/4 pound bags of fish food at $6.98 per pound. Approximately how much did Amber spend on pet food?

Answers

Answer:

[tex]Total = \$73[/tex]

Step-by-step explanation:

Given

[tex]Three\ 8lb = \$2.25/lb[/tex] --- Dog Food

[tex]Two\ 4lb = \$1.75/lb[/tex] ----- Cat Food

[tex]Three\ \frac{1}{4}lb = \$6.98[/tex] -------- Fish Food

Required

Determine the amount spent

For Dog Food

[tex]1\ lb = \$2.25[/tex]

Amber bought 8lb.

So, that is:

[tex]8 * 1\ lb = \$2.25 * 8[/tex]

[tex]8\ lb = \$18[/tex]

He bought 3 of those;

[tex]Cost = 3 * \$18[/tex]

[tex]Cost = \$54[/tex]

For Cat Food

[tex]1\ lb = \$1.75[/tex]

Amber bought 4lb

So, that is:

[tex]4 * 1\ lb = 4 * \$1.75[/tex]

[tex]4\ lb = \$7[/tex]

He bought 2 of those;

[tex]Cost =2 * \$7[/tex]

[tex]Cost =\$14[/tex]

For Fish Food

[tex]1\ lb = \$6.98[/tex]

Amber bought 1/4lb

So, that is:

[tex]\frac{1}{4} * 1\ lb = \$6.98 * \frac{1}{4}[/tex]

[tex]\frac{1}{4}\ lb = \$1.745[/tex]

He bought 3 of those;

[tex]Cost = 3 * \$1.745[/tex]

[tex]Cost = \$5.235[/tex]

Total amount spent  is:

[tex]Total = \$54 + \$14 + \$5.235[/tex]

[tex]Total = \$73.235[/tex]

[tex]Total = \$73[/tex] (approximated)

Help please I’ll give you 25 points

Answers

Answer: Choice D) [tex]y = \pm \sqrt{x+5}[/tex]

The steps to finding the inverse will have us swap x and y. Afterward, we solve for y

[tex]y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\[/tex]

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

Extra info:

The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into [tex]y = \pm \sqrt{x+5}[/tex] leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on [tex]y = x^2-5[/tex] to make it a one-to-one function, to make the inverse a function. One possible domain restriction is [tex]x > 0[/tex] which would lead to the inverse function [tex]y = \sqrt{x+5}[/tex]
