A factory produces 1,250,000 toys each year. the number of toys is expected to increase by about 150% per year. which model can be used to find the number of toys, n (in millions), being produced in t years? n = startfraction 2.5 (1.5) over t endfraction, t not-equals 0 n = 1.5 t squared 1.25 n = 1.5 t 1.25 n = 1.25 times 2.5 superscript t

Answers

The model that can be used to find the number of toys is  1.25* (2.5) ⁿ.

What is meant by an increment of 150%?

An increment of 150% means an increment of 1.5 times of initial value.

Number of toys initially = 1,250,000 or 1.25 millions

Number of toys after a year = 1.25 + 1.25*1.5 = 1.25*(2.5)¹

Number of toys after two year =1.25 * 2.5+ 1.25*2.5*1.5 = 1.25*(2.5)²

Number of toys after three year = 1.25* (2.5)³

So, Number of toys after n year = 1.25* (2.5)

Therefore, the model that can be used to find the number of toys is  1.25* (2.5) ⁿ.

angle c and angle d are supplementary angles.if the measure of angle d is 80 degress,what is the measure of angle c

Answers

Answer:

C = 100

Step-by-step explanation:

Supplementary angles equal 180 degrees

180 - 80 = 100

Answer:

m∠C = 100°

Step-by-step explanation:

Supplementary angles are angles that add up to 180°. We are given m∠D as 80°.

This means that c + 80 = 180

Step 1: Subtract 80 from both sides.

[tex]c+80-80=180-80[/tex] [tex]c=100[/tex]

Therefore, the answer is 100°.
