Find the volume of this square based pyramid. 10 cm 8 cm 8 cm V = [?] cm3

oksano4ka [1.4K]

Answer:

213.3

Step-by-step explanation:

The volume of a pyramid is 1/3 base times height.

Using this formula, our square base is 8*8, or 64 square units.

Multiplying that by the height, 10. We get 64*10, 640.

Finally dividing by 3, we have 213.3333333333...

Rounding that to the nearest tenth, 213.3.

The listed price of the video game was $34, but the price with tax came to $37.40. Find the percent sales tax.

Katarina [22]

Answer:

10%

Step-by-step explanation:

we want to find what % of 34 is 37.40

so, we will use the following equation:

$\frac{part}{whole} = \frac{percent}{100}$

for this scenario:

part = 37.40

whole = 34

percent = x

now plug in:

$\frac{37.40}{34} = \frac{x}{100}$ cross multiply

34x = (37.40)(100)

34x = 3740 divide both sides by 34

x = 110%

now we know that with tax, we paid 110% of the video game's price

110 - 100 = 10%

so the percent sales tax is 10%

just to check...

34 • 1.10 = $37.40

34 • .10 = 3.40

34 + 3.40 = 37.40

Polygon ABCD is translated to create polygon A′B′C′D′. Point A is located at (1, 5), and point A′ is located at (-2, 1). What is

wolverine [178]

Distance formula = sqrt[(x1 - x2)^2 + (y2-y1)^2]
D = sqrt[(1 + 2)^2 + (5 - 1)^2]
D = sqrt[3^2 + 4^2]
D = sqrt(9 + 16)
D = sqrt(25)
D = 5
