Answer:

The missing number would be 22.

Step-by-step explanation:

The missing number would be, lets say <em>x</em>.

(<em>x</em> - 8) / 7 = 2

First, lets multiply 2 by 7.

2 * 7 = 14

Next, lets add 8 to 14.

8 + 14 = 22

The missing number would be 22.

To check this answer, subtract 8 from 22 which would be 14.

Then divide by 7 which would be 2. This answer is correct.

Therefor, the missing number, or x, would be 22.

Hope this helps!

The diameter of a spherical balloon that is being filled with air is increasing at the rate of 3 inches more than the time, t. W

Harrizon [31]

Answer:

$V=36 \pi$ cubic inches

Step-by-step explanation:

Diameter is increasing at 3 inches more than time, When t = 3

Diameter (d) = 3+3 = 6

d = 6

Radius is HALF of diameter, so

r = 6/2 = 3

Now, the volume of a sphere is given by the formula:

$V=\frac{4}{3}\pi r^3$

Putting r = 3, we get:

$V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}\pi (3)^3\\V=36 \pi$

The volume would be 36π

(-1,9) because Y is always the second number and -3*-1=3 so 9=3+6 basically :)

Given the fact that AB≈AD, then 35 is also the angle measure of ADB. The sum of the angles of a triangle =180. 35+35=70. 180-70=110

X=110°

50 point! Look at the picture attached. I will mark brainliest!

Answer:

22°

Step-by-step explanation:

Triangle KJL ≅ Triangle MJL (RHS)

[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]

we come up to the conclusion that 4x + 6 = 3x + 10

x = 4

∴angle KJL = 4(4) + 6 = 22°
