Answer:

x = ±10

Step-by-step explanation:

4x² - 400 = 0

Add 400 to both sides

4x² = 400

Divide both sides by 4

x² = 100

Take the square root of both sides

x = ±10

Hershey’s is making pumpkin-shaped chocolates for Halloween. These are spherically formed with a radius of 2 cm. What is the min
Lady_Fox [76]

Answer:

Sa = 1.5*V

Step-by-step explanation:

We have that the surface area of a sphere has the following formula:

Sa = 4*pi*r^2

we know that r = 2, so if we replace it, we're left:

Sa = 4*pi*(2^2)= = 4*pi*4

Sa = 16*pi

Now, the volume has the following formula:

V = 4/3*pi* r^3

Replacing it is our job:

V = 4/3*pi* (2^3) = 4/3*pi*8

V = 32/3*pi

Now, Sa/V, it would remain:

Sa/V = 16*pi / 32/3*pi

Sa/V = 48/32 = 1.5

Therefore, Sa = 1.5*V

Luis wants to buy a skateboard that usually sells for $79.74. All merchandise is discounted by 12%. What is the total cost of th
eduard

Answer:

75.26

Step-by-step explanation:

Most sales taxes work by not being calculated until cash in some form changes hands. So you take the discount first and then you add the sales tax on the new amount.

Take the discount first

Original cost = 79.74

Discount amount = 79.74 * 12% = 79.74 * 12/100 = 9.57

New price = 79.74 - 9.57 = 70.17

Now you are ready to add on the sales tax

70.17 * 7.25/100 = 5.09

The total is 70.17 + 5.09 = 75.26
