The answer would be 84 because 2miles is equal to 24 minutes so you would break that in half down to one mile. One mile would be 12 minutes. So you would multiply 12 times 7 which equals 84 which would be your answer.

Help me with khan geometry. (Explain or give answer no link to answer thx)

NikAS [45]

Answer:

$\boxed{\sf 200\pi}$

Step-by-step explanation:

We know that the volume of a cone:-

$\boxed{\sf \pi r^2\cfrac{h}{3}}$

(r = 10) (h = 6)

$\sf \pi \times 10^2\times\cfrac{6}{3}$

Divide numbers:-

$\sf \cfrac{6}{3}=\boxed{2}$

$\sf 10^2\times \:2\pi$

$\sf 100\times \:2\pi$

Multiply numbers:-

$\boxed{\sf 200\pi}$

Therefore, your answer is 200π³

We could also multiply 200 by 3.14 which will give you 628 units³.

Write the expressions "Four times the difference of a number and 7 is 32", "One third of a number is 12 less than the number its

Anna71 [15]

Part 1) "Four times the difference of a number and $7$ is $32$ "

Let

x--------> the number

we know that

the expressions is equal to

$4(x-7)=32$

therefore

the answer part 1) is

$4(x-7)=32$

Part 2) "One third of a number is $12$ less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

$\frac{1}{3} x=(x-12 )$

therefore

the answer part 2) is

$\frac{1}{3} x=(x-12 )$

Part 3) "Ten increased by the quotient of a number and $2$ is $-15$ "

Let

x---------> the number

we know that

the expressions is equal to

$10+ (\frac{x}{2} )= -15$

therefore

the answer Part 3) is

$10+ (\frac{x}{2} )= -15$

Part 4) "One less than the product of a number and $3$ is $5$ more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

$(3x)-1=5+x$

therefore

the answer Part 4) is

$(3x)-1=5+x$
