Given a cone with a volume of 288, and height 7 in., find the base radius of the cone. Use 3.14 for pi. Round your answer to the

jek_recluse [69]

Answer:

The radius of the base is $r=6.3\ in$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have

$V=288\ in^{3}$

$h=7\ in$

$\pi=3.14$

substitute and solve for r

$288=\frac{1}{3}(3.14)r^{2} (7)$

$864=(3.14)r^{2} (7)$

$r^{2}=864/[(3.14)(7)]$

$r=6.3\ in$

One number is 2 more than another. The difference between their squares is 24.

kkurt [141]

Answer: The numbers are 7 and 5

Step-by-step explanation:

Let the first number be x and the second number be y.

From the first statement , it was said that one of the number is two more than the other , that is

x - y = 2 .................. equation 1

square of x is $x^{2}$ and the square of y is $y^{2}$ , the difference between thier squares implies

$x^{2}$ - $y^{2}$ = 24 .............. equation 2

solving the resulting simultaneous equations by substitution method:

From equation 1 , make x the subject of the formula , that is

x = 2 + y ............. equation 3

substitute equation 3 into equation 2 , we have

$(2+y)^{2}$ - $y^{2}$ = 24

Expanding , we have

$y^{2}$ + 4y + 4 - $y^{2}$ = 24

4y + 4 = 24

Subtract 4 from both sides

4y = 20

y = 20/4

y = 5

substitute y = 5 into equation 3 , we have

x = 5+ 2

x = 7

Therefor the numbers are 7 and 5

Reggie has $36.40 in nickels and $36.40 in dimes. What is the ratio of the number of nickels to the number of dimes that Reggie

Dmitry [639]

D 2:1, because a dime is worth twice as much as a nickel

Because the question has number of nickels listed first in the ratio that makes the answer 2:1 as opposed to B 1:2. Also, two nickels equal the same amount as one dime so for every two nickels there is one dime. In this case, there are 728 nickels and 364 dimes. 728/364 = 2/1 (simplifies down to the fourth ratio given)

These 20 ages of children on a school bus are in order from least to greatest. 5, 5, 5, 6, 6, 7, 7, 8, 9, 10, 10, 11, 12, 12, 12

umka2103 [35]

Answer:

the interquartile range is the Q3-Q1 where Q3 is 75th percentile and Q1 is the 25th percentile.

so the total count is 20 so 25 percentile is 25% of 20 =5 and 75th percentile is 75% of 20 = 15 and since the number are already arranged in order we just pick the 15th number-5th number thus, our answer is

12-6 = 6
