Answer:

Slope = -3

Step-by-step explanation:

Slope = $\frac{rise}{run}$

Slope = $\frac{3-9}{2-0}$

Slope = $\frac{-6}{2}$

Slope = -3

Three numbers X, Y, and Z are in the ratio 2:7:8. If 12 is subtracted from Y, then three numbers form a geometric sequence (in t

melomori [17]

Answer:

(X, Y, Z) = (8, 28, 32)

Step-by-step explanation:

The ratio units will form a geometric sequence if the middle one is the square root of the first and last:

Y' = √(2·8) = 4

To get this value from 7, we must subtract 3. In the real sequence we must subtract 12, so each "ratio unit" must stand for 12/3 = 4 real units, and the real numbers X, Y, Z are 2·4 = 8, 7·4 = 28, 8·4 = 32.

(X, Y, Z) = (8, 28, 32)

(X, Y-12, Z) = (8, 16, 32) . . . . a geometric sequence with a ratio of 2

Find the volume of the sphere.

Ksju [112]

Answer:

$\frac{1}{48} \pi$ units cubed

Step-by-step explanation:

The volume of a sphere is: $\frac{4}{3}\pi r^{3}$

We know the radius r = 1/4, so we just plug this into the equation:

(4/3)* $\pi$ *(1/4)^3 = (4/3)* $\pi$ *(1/64) = $\frac{1}{48} \pi$

So, the answer is $\frac{1}{48} \pi$ units cubed.

is planning schedules for 30 students Sixteen students say they want to take French, 16 want to take Spanish, and 11 want to tak

ivann1987 [24]

Answer: There are 7 students who want French only.

Step-by-step explanation:

Since we have given that

Number of students is planning schedules = 30

Number of students who want to take French = 16

Number of students who want to take Spanish = 16

Number of students want to take Latin = 11

Number of students who take both French and latin = 5-3 =2

Number of students who take French and Latin and Spanish as well = 3

Number of students who only want Latin = 5

Number of students who only want spanish = 8

According to venn diagram, we get that

$a+b+g+f=16\\\\c+d+e+g=11\\\\b+e+f+g=16$

So, it becomes,

$c+d+e+g=11\\\\5+2+e+3=11\\\\e=11-(5+2+3)=1$

Similarly,

$b+e+f+g=16\\\\8+1+f+3=16\\\\12+e=16\\\\e=16-12\\\\e=4$

Similarly,

$a+d+g+f=16\\\\a+2+3+4=16\\\\a=16-(2+3+4)\\\\a=16-9\\\\a=7$

Hence, there are 7 students who want French only.
