An item is on sale for $56. If this price represents a 25% discount from the original price, what is the original price?

Answer:

432/19 should be the answer?

Answer:

x = 22.7

Step-by-step explanation:

(3x + 23) + (7x - 4) + (9x - 6) + 95 = 540

combine all like terms

19x + 108 = 540

solve

subtract 108 from both sides

19x = 432

divide 19 from both sides

x = 22.7

Answer:

(2/5)√5

Step-by-step explanation:

from the sine rule (see attached for reference), we can construct the following relationship

12/sinθ  = (6√5) / sin 90°

recall that sin 90° = 1, hence our equation becomes:

12/sinθ  = (6√5) / 1

12/sinθ  = (6√5)   (rearranging)

12 ÷ (6√5)  = sin θ

sin θ = 12 / (6√5)

sin θ = 2 / √5   (moving radical to numerator by multiplying by √5/√5)

= 2 / √5     x     √5/√5

= 2√5 / 5

= (2/5)√5

Answer:

0.6

Step-by-step explanation:

Given the trapezoid formula:

1/2(b1+b2/2)xH

We are given the numbers for the trapezoid:

0.3,0.9,1

To solve this here is what we are going to do.

1/2(0.9+0.3)x1

So add 0.9+0.3=1.2

Then Divide 1.2/2=0.6

So multiply 0.6 x 1=0.6

0.6 is your answer

Answer:

129 degrees

Step-by-step explanation:

One circle is 360 degrees, so add up all the degrees, including x:

35 + 55 + 141 + x = 360

231 + x = 360

x = 360 - 231

x = 129 degrees

Answer: R = √(3*r^2)

Step-by-step explanation:

For a cylinder with radius r and height H, the volume is:

V = pi*r^2*H

For a cone of height H, and with a base of radius R, the volume is:

V = (1/3)*pi*R^2*H

In this case, we know that both figures have the same height, and the same volume, then we can write:

pi*r^2*H = (1/3)*pi*R^2*H

Now we can divide by pi in both sides to get:

(pi*r^2*H)/pi = ((1/3)*pi*R^2*H)/pi

r^2*H = (1/3)*R^2*H

Now we can divide both sides by H:

(r^2*H)/H = ((1/3)*R^2*H)/H

r^2 = (1/3)*R^2

Now we want to write R in terms of r.

Then we need to isolate R in the above equation:

r^2 = (1/3)*R^2

3*r^2 = R^2

√(3*r^2) = R

R = √(3*r^2)

Answer:

Step-by-step explanation:

3/3= 1 whole

14/3 - 3/3 =11/3 - 3/3= 8/3 - 3/3= 5/3 - 3/3= 2/3

No more 3/3, or 1 whole, can be subtracted, so you add the number of 3/3, or 1 whole, that you subtracted, which adds up to 4 wholes, and then you add the 2/3, which would equal 4 and 2/3.

Answer:

6y represents Multiplication.

Answer:

x=20, y=100

Step-by-step explanation:

3x+2x=7x-40

5x=7x-40

2x=40

x=20

7x-40=y

140-40=y

100=y

y=100

According to the exterior angle theorem, the two remote interior angles are equal to the exterior angle. This is why we set 3x+2x equal to 7x-40.

According to the vertical angles theorem, two angles that are opposite and formed by two intersecting straight lines are equal. This is why we set 7x-40 equal to y.

Because we already knew that x was 20, we could put it into our equation. (7*20)-40=y.
