Answer:

It will take 21 years.

Step-by-step explanation:

First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.

4.5 + 1.75x = 40

Subtract 4.5 from both sides. This cancels out the +4.5.

1.75x = 40 - 4.5

Subtract 4.5 from 40 to get 35.5.

1.75x = 35.5

Divide both sides by 1.75. This cancels out the *1.75.

x = 35.5/1.75

Expand 35.5/1.75 by multiply both the numerator and denominator by 100.

x = 3550/175

Reduce 3550/175 by canceling out 25.

x = 142/7 = 20 2/7

Go up by one from 20 to get the answer of 21 years.

Determine the volume of the parallelepiped with one vertex at the origin and the three vertices adjacent to it at (2, â1, â1), (

valentinak56 [21]

Answer:

Step-by-step explanation:

Here is the complete question

Find the volume of the parallelepiped with one vertex at the origin and adjacent vertices at (1, 0, -3), (1, 2, 4), and (5, 1, 0).

Solution

We find the volume of the parallelepiped by making a 3 × 3 column matrix whose columns are the corresponding coordinates of the vertices of the parallelepiped.

So, (1, 0, -3), (1, 2, 4) and (5, 1, 0)

$A = \left[\begin{array}{ccc}1&1&5\\0&2&1\\-3&4&0\end{array}\right]$

The determinant of A is the volume of the parallelepiped. So,

detA = 1(2 × 0 - 4 × 1) - 1(0 × 0 - (-3) × 1) + 5(0 × 4 - (-3) × 2)

= 1(0 - 4) - 1(0 + 3) + 5(0 + 6)

= 1(-4) - 1(3) + 5(6)

= -4 - 3 + 30

= 23

So the volume of the parallelepiped is 23

The volume of this sphere is 972pi cubic inches. What is its radius?

maria [59]

4/3pi *r3 = 972pi
Divide both side by pi

4/3 *r3 = 972

r3 = 972* 3/4

r3 = 729

r = the square root of 729 to the third power (I don't know if I'm expressing this correctly but answer is 9, hope you get that)

r = 9 that's your answer.

Hope it's correct, appreciate if you could let me know

Sixty-five % of the spectators at the basketball game are male and there are 280 female spectators.

notsponge [240]

A). Simply, subtract 100 percent minus 65 percent, which gives you the answer 35 percent.

b). So, to find the total number you add 280 plus 65 percent, which gives you the answer, 462.

c). To find this, simply subtract 462 minus 280, which gives you the answer, 182.

Hope this helps!
