Exponential word problems almost always work off the growth/decay formula, A = Pert, where "A" is the ending amount of whatever you're dealing with (money, bacteria growing<span> in a petri dish, radioactive decay of an element highlighting your X-ray), "P" is the beginning amount of that same "whatever", "r" is the growth</span>

Find the measure of the remote exterior angle. m∠x=(198−5n)°m∠y=(5n+37)°m∠z=(n+7)°
MrMuchimi

The value of the angle ∠x will be ∠x = 128°. Then the correct option is C.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The triangle is given below.

The sum of the two interior angle is equal to the third exterior angle.

m∠x = (198 − 5n)°

m∠y = (5n + 37)°

m∠z = (n + 7)°

We know that

∠x = ∠y + ∠z

198 - 5n = 5n + 37 + n + 7

       11n = 154

          n = 14

Then the value of the angle ∠x will be

∠x = 198 – 5 × 14

∠x = 128°

Then the correct option is C.

The complete question is given below.

More about the triangle link is given below.

Two numbers are in the ratio of 3 to 4. If the minor is 27, find the sum of both.
german

Answer:

Step-by-step explanation:

First we must find the missing number, for that we apply a simple rule of three:

3. 4

27 ------ x

x = 27 (4) / 3 = 36

Now we just do the sum:

27 + 36 = 63

Cannonballs are stacked In a pyramid shape with a base of 5 cannonballs on a side. How many cannonballs in all are in the stack
Vadim26 [7]

Answer:

The total number of balls in the pyramid will be 55.

Step-by-step explanation:

Cannonballs are stacked In a pyramid shape with a base of 5 cannonballs on a side.

Therefore, at the base, the number of balls is 5².

In the layer above the base layer, there are 4 balls on each side.

So, in the layer above the base layer, the number of balls is 4².

Similarly, in the next levels, the number of balls will be 3², 2² and 1.

Therefore, the total number of balls in the pyramid will be (5² + 4² + 3² + 2² + 1) = 55. (Answer)

The answer for the first slot is Alternate Interior Angles Theorem
Angle B and angle G are inside the "train tracks" formed by AB and GH. They are on opposite sides of the transversal line BG.

Along a similar line of reasoning, the answer for the second slot is Alternate Exterior Angles Theorem
The two parallel lines in question are AC and FH. The transversal line is FC. Angles ACB and HFG are on the exterior of the "train tracks" formed by the parallel lines.
