PLEASE HELP The ratio of boots to sandals in a shoe store is 8:3. If there are 245 more boots that sandals in the store, how many boots are there?

Answers

Answer 1

Answer: x - the number of boots
y - the number of sandals

The ratio of boots to sandals is 8:3.
$(x)/(y)=(8)/(3) \n8y=3x \ny=(3)/(8)x$

There are 245 more boots than sandals.
$y+245=x \ny=x-245 \n \ny=y \n(3)/(8)x=x-245 \n(3)/(8)x-x=-245 \n(3)/(8)x-(8)/(8)x=-245 \n-(5)/(8)x=-245 \nx=-245 * (-(8)/(5)) \nx=49 * 8 \nx=392$

There are 392 boots.

chad has two pieces of wood. one piece is 7/12 foot long. second is 5/12 foot longer than forst. how long is second piece

Answers

Answer:

Step-by-step explanation:

Alright lets get started.

Clad has two pieces of wood.

The length of first wood piece is= $(7)/(12)$

length of the second wood piece is $(5)/(12)$ longer than the first wood piece.

So, the length of the second wood piece is = $(7)/(12)+(5)/(12)=(12)/(12)=1$

Hence, the length of the second wood piece is 1 foot long. : Answer

Hope it will help.

1st piece = 7/12.

2nd = 5/12 longer.

2nd = 7/12 + 5/12 = (7 + 5) / 12 = 12/12 = 1.

2nd piece = 1 foot long.

Brandon earns $6 for every shirt he sells. Which equation could Brandon used to determine the amount of money he earns (E) for any number of shirts (s) he sells

Answers

Simple,

since he has no money to begin with just write your equation..

E=6s

Which basically means, if he sells 1 shirt:

E=6(1)
E=$6

If he sells 2 shirts:

E=6(2)
E=$12

And so on and so forth, thus, your equation is E=6s.

Answer:

C)E = 6's

His seat is in the terrace section, about 198 feet from the center of the court. If the angle of depression to the court is 57° which of the following represents the height Kylie sitting? Round to the nearest tenth.

Answers

Answer:

Kylie is sitting 166.1 ft above the court

Step-by-step explanation:

Given the information. A diagram as shown can be drawn.

As this situation creates a right triangle, we can use the sin function to solve for the height.

We can set up the equation as follows

$sin(57)=(h)/(198)$

Then we can solve for h

$h=198sin(57)$

When solved

h = 166.056 ft

Which rounds to

h = 166.1 ft

I’m If Linda age is decreased by 36, the result is twice Linda’s age. how old is linda?

Answers

Answer:

x=lindas age

3 times lindas age (3 time x or 3x) is decreased by 36 (-36), the result (=) is twice lindas age (2 times x or 2x)

now we have

3x-36=2x

subtract 2x

x-36=0

add 36

x=36

age=36
