A bag contains only cherry and grape gumballs. The ratio of cherry gumballs to grape gumballs in the bag is 7:6. What is the rat

Ede4ka [16]

So,

There are 7 cherry gumballs and 6 grape gumballs.

The total gumballs is 13.

Therefore, the ratio of grape gumballs to total gumballs is 6:13.

The following problem describes procedures that are to be applied to numbers. Repeat the procedure for four numbers of your choi

mart [117]

Answer:

Conjecture: For every number x, the result of the is 2x

Step-by-step explanation:

First Number: 8

Multiply by 88: $88 * 8 = 704$

Add 88: $704 + 88 = 792$

Divide by 44: $792/44 = 18$

Subtract 2: $18 - 2 = 16$

Second: 10

Multiply by 88: $88 * 10 = 880$

Add 88: $880+88=968$

Divide by 44: $968/44=22$

Subtract 2: $22-2=20$

Third: 5

Multiply by 88: $88*5 = 440$

Add 88: $440+88=528$

Divide by 44: $528/44=12$

Subtract 2: $12-2=10$

Fourth: 2

Multiply by 88: $88*2=176$

Add 88: $176+88=264$

Divide by 44: $264/44=6$

Subtract 2: $6-2=4$

On a general terms:

Let the number be x.

Multiply by 88: $88x$

Add 88: $88x + 88$

Divide by 44: $\frac{88x + 88}{44} = \frac{88x}{44} + \frac{88}{44} = 2x+2$

Subtract 2: $2x + 2 - 2 = 2x$

Notice that for every input x, the result is 2x

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that form

anyanavicka [17]

The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees

<h3>How to determine the central angle?</h3>

The given parameters are:

Area = 75π cm^2
Radius, r = 15 cm

The area is calculated using

Area = α/360 * πr^2

So, we have:

α/360 * π * 15^2 = 75π

Evaluate the exponent

α/360 * π * 225 = 75π

Divide both sides by 75π

α/360 * 3 = 1

Multiply

α/120 = 1

Multiply both sides by 120

α = 120

Hence, the measure of the central angle that forms the sector is 120 degrees
