It goes down by 5. -5 would also be another way of saying that.

Find the discount. Original price: $0.75 Discount: ?? Sale price: $0.15

Svetach [21]

Answer:

80%

Step-by-step explanation:

0.75 ⇒ 100%

0.15 ⇒ x%

0.75x = 100·(0.15)

0.75x = 15

x = 15/(0.75)

x = 1500/75

x = 20%

100% - (discount) = x%

100% - (discount) = 20%

discount = 100%-20%

discount = 80%

Solve the equation 4 x minus 7 space equals space 45 for x.

zimovet [89]

Answer:

x = 13

Step-by-step explanation:

For this problem, we will simply uses properties of addition and multiplication to isolate the x variable for the following equation.

4x - 7 = 45

Now consider the following. First, we must isolate the x term by adding 7 to both sides.

4x - 7 = 45

4x -7 +7 = 45 +7

4x = 52

Second, let's further isolate x by multiplying both sides by 1/4 to create a coefficient of 1 Infront of the x variable.

4x = 52

(1/4) * 4x = 52 * (1/4)

x = 13

Hence, we have solved the equation 4x-7=45 where x=13.

Cheers.

<h3>Given:</h3>

h= 19 ft
r= 12 ft

h= Height
r= Radius

The volume of the given cone.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{1}{3}\pi{r}^{2}h}$

$\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}$

Let's solve!

Substitute the values according to the formula.

$V=\frac{1}{3}×3.14×{12}^{2}×19$

$\large\boxed{V=2863.68 \: {ft}^{3}}$

Therefore, the volume of the given cone is 2863.68 cubic feets.
