When a 49 pound weight is attached to a spring, the spring
stretches 7 inches. Assume that the length of the spring y varies directly
with the weight attached x. Write and solve a direct variation equation to
find the length of the spring when a 63 pound weight is attached.

Answers

Answer 1

im not for sure but I think the answer is 9! my reasoning is below,,

Step-by-step explanation:

[tex] \frac{49}{7} = \frac{63}{x} [/tex]

do the crossing method and it would result in this

(49×x) = (63×7)

after simplifying both sides

49x = 441

divide both sides by 49 and the result will be

x = 9 !!

One year ago, a tiger cub was 5 feet shorter than its mother. However, it grew 2 feet, and now its mother is only twice its size. How big was the tiger cub one years ago?

Answers

Answer:

1 foot

Step-by-step explanation:

Since the cub is 1 foot, that means the mother is 6 ft.

Assuming that the mother does not grow and the cub grows 2 feet, a year later the cub is 3 feet and the mother is 6 feet.

3 is half of 6, meaning the mother is twice the cub.

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $3995 to rent trucks plus an additional fee of $225.75 for each ton of sugar. The second company charges $5500 to rent trucks plus an additional fee of $150.50 for each ton of sugar.

Answers

Given :

The Sugar Sweet Company will choose from two companies to transport its sugar to market.

The first company charges $3995 to rent trucks plus an additional fee of $225.75 for each ton of sugar.

The second company charges $5500 to rent trucks plus an additional fee of $150.50 for each ton of sugar.

To Find :

How, many tons of sugar will cost same in both companies.

Solution :

For company 1 :

P1 = (225.75)x + 3995

For company 2 :

P2 = (150.50)x + 5500

For same cost :

P1 = P2

(225.75)x + 3995 = (150.50)x + 5500

x( 225.75 - 150.50 ) = ( 5500- 3995)

x( 75.25 ) = 1505

x = 20

Therefore, 20 tons of sugar will cost same.

Hence, this is the required solution.

In a recent year, 23% of all college students were enrolled part-time. If 6.2 million college students were enrolled part-time that year, what was the total number of college students?

Answers

Answer:

17,222,222

Step by Step Solution:

If 26% equals 6,200,000, then

1% equals 6,200,000/23, and

100% equals (6,200,000/23)*100 = 17,222,222.222222222222222222222222

Hence, there were about 17,000,000 (seventeen million) students.

To be a bit closer to the number, there where about 17,222,222 students.

And finally we have:

5.56666666667 as a fraction equals 556666666667/100000000000

What is the slope of a line parallel to the line whose equation is 9x – 3y = 81. Fully
reduce your answer.

Answers

Answer:

Ok so right now that is in standard form (Ax+by=C) and we want to get this into y=mx+b form so that we can easily identify the slope. To do that we need to get y alone by folowing these steps:

9x-3y=81

9x-9x-3y=81-9x (in this step we are just getting rid of the x's from the left side so we can get y alone but since we subtract x from that side we need to subtract the same amount of x's on the other)

-3y=81-9x

-3y/-3=81-9x/-3 (finally to get y alone we need to divide by a -3. This is because any negative number multiplied or divided by another negative will give us a positive. If we divide by 3 then y will be negative which is incorrect. We have to divide by -3 on each side)\

y=81-9x/-3 -----> y=-27+3x ( in this part we have to divide everything on the right side of the equation by -3 as we did on the left side. 81/-3 = -27 and -9x/-3 = +3x.

our new equation is y=-27+3x although the proper form is y=mx+b.

all we need to do now is flip the 3x and -27 for this equation to match y-mx+b form. M in the equation represents the slope of an equation.

y=-27+3x---> y=3x-27

in this equation 3 is m and m represents the slope. For an line to be parralel to one another they must have the same slope. Therefore the slope of a line parallel to that equation is 3.

Step-by-step explanation:

The Slope of a line parallel to the line whose equation is 9x – 3y = 81 is 3.

What is the Slope of a line?

A slope of a line is the change in y coordinate with respect to the change in x coordinate.

Given that the slope of a line parallel to the line whose equation is

9x – 3y = 81

Reducing the Equation in form of y = mx + c, where m is the slope,

9x - 3y = 81

3y = 9x - 81

y = 3x - 27

Since, two line when parallel have equal slope, so the slope of the given line is 3.

Hence, The Slope of a line parallel to the line whose equation is

9x – 3y = 81 is 3.

D.) Translate GHJ by the directed line segment GT. Rotate G’H'J using T as the center by angle H'ST. Reflect G"H"J over ST.

Answers

The answer is A I think

The correct option is A. Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

There are four types of rigid motions that we will consider translation , rotation, reflection, and glide reflection.

Here we have to rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Hence option A is correct that is Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
