Answer:

Step-by-step explanation:

slant height is given. Using Pythagorean theorem to find height.

h² = 10² - 5²

= 100 - 25

h² = 75

h = √75

h = 8.66 cm

Volume =(1/3)πr²h

=\frac{1}{3}*3.14*5*5*8.66\\\\=\frac{679.83}{3}\\\\

= 226.62 cubic cm

Mr. Black bought 2 magazines for $9.95 each and 1 book for $14.95. If the sales tax is 6%, what is the total cost of Mr. Black's
miss Akunina [59]

Answer:

$36.94

Step-by-step explanation:

Okay, so. This is what we do. There is two magazines and they cost 9.95 each multiply 9.95 times 2

9.95 x 2 = 19.90

Okay, then he buys a book for 14.95 we add 19.9. and 14.95

19.90 + 14.95 = 34.85

Then we have a sales tax of 6% we would multiply 34.85 time 6%

34.85 x 6% = 2.09

Then we would add. 34.85 + 2.09

34.85 + 2.09 = 36.94

Therefore your answer is $36.94

Hope this helps!!!

the ratio is 3:2

Multiply by x

3x:2x

Add them together and set equal to 90

3x+2x=90

5x=90

Divide each side by 5

5x/5 = 90/5

The value of x varies with y and when x=1/3 y=12 write an equationto represent the variation
Virty [35]

Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = \frac{1}{3}, y = 12, then

k = \frac{y}{x} = \frac{12}{\frac{1}{3} } = 12 × 3 = 36

y = 36x ← equation of variation
