Flauer [41]

Answer:

20 feet.

Step-by-step explanation:

Pythagoreans theorem states that a^2 + b^2 = c^2

a = 12, squared = 144

b = 16, squared = 256

144 + 256 = 400

√400 = 20

20 feet is the answer.

Hope this helps.

A produce store sold 45 red apples. If the ratio of red apples to green apples sold was 5 : 2, what is the combined amount of re

lisabon 2012 [21]

The ratio of Red Apples to Green Apples is 5:2. The proportion of red apple is 5/7.

The store sold 45 red apples.

So the combined amount of red and green apples sold = No of red apples sold divided by the proportion of red apples = 45/ (5/7) = 63

The combined amount of red and green apples sold is 63 apples.

The news listed that the al?rage price Of a gallon Of gasoline

Virty [35]

Answer:

b. between $3.04 and $3.36

Step-by-step explanation:

Given,

Price of 1 gallon of gasoline = $3.20

Margin of Error = 5%

We have to find out average cost of gallon of gasoline.

For this, we have to find out 5% of the price of gasoline. Which is calculated by dividing 5 by 100 and then multiply it by 3.20.

Amount of margin of error = $\frac{5}{100}\times3.20 = 0.16$

Hence The margin of error is ±, So we will subtract the amount of margin of error with actual amount of 1 gallon of gasoline. Also we will add the amount of margin of error with actual amount of 1 gallon of gasoline.

Margin of error 1 = $3.20-0.16= \$3.04$

Margin of error 2 = $3.20+0.16= \$3.36$

Hence the Average cost of a gallon of gasoline should be between $3.04 and $3.36.

Please solve with explanation I’ve been asking all day (this is not a multiple choice question)

Anastaziya [24]

Answer:

a) $SA = 522.9~cm^2$

b) $V_{cone} = 670.2~cm^3$

c) $V_{empty} = 1340.4~cm^3$

Step-by-step explanation:

a)

For a cone,

$SA = \pi r (L + r)$

where L = slant height

$L = \sqrt{r^2 + h^2}$

We have r = 8 cm; h = 10 cm

$L = \sqrt{(8~cm)^2 + (10~cm)^2}$

$L = \sqrt{164~cm^2}$

$SA = (\pi)(8~cm)(\sqrt{164~cm^2} + 8~cm)$

$SA = 522.9~cm^2$

b)

$V_{cone} = \dfrac{1}{3}\pi r^2 h$

$V_{cone} = \dfrac{1}{3}(\pi)(8~cm)^2(10~cm)$

$V_{cone} = 670.2~cm^3$

c)

$V_{cylinder} = \pi r^2 h$

empty space = volume of cylinder - volume of cone

$V_{empty} = V_{cylinder} - V_{cone}$

$V_{empty} = \pi r^2 h - \dfrac{1}{3}\pi r^2 h$

$V_{empty} = (\pi)(8~cm)^2(10~cm) - \dfrac{1}{3}(\pi)(8~cm)^2(10~cm)$

$V_{empty} = 1340.4~cm^3$
