Answer:

TQ = 24

Step-by-step explanation:

Δ RST and Δ RPQ are similar, thus ratios of corresponding sides are equal, that is

[tex]\frac{RS}{RP}[/tex] = [tex]\frac{RT}{RQ}[/tex] , substitute values

[tex]\frac{15}{35}[/tex] = [tex]\frac{18}{RQ}[/tex] ( cross- multiply )

15 RQ = 630 ( divide both sides by 15 )

RQ = 42

Then

TQ = RQ - RT = 42 - 18 = 24

An initial population of 415

ducks increases at an annual

rate of 32%. Write an

exponential function to model

the duck population.

Answers

Answer:

The exponential function to model the duck population is:

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

Step-by-step explanation:

In order to calculate the duck population you can use the formula to calculate future value:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:

f(n)=415*(1+0.32)^n

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

The dimensions of a box are x, 2x, and 3x. Each dimension is increased by 2. Calculate the volume of the box.

Answers

9514 1404 393

Answer:

  6x^3 +22x^2 +24x +8

Step-by-step explanation:

The dimensions of the larger box are ...

  (x+2), (2x+2), and (3x+2)

The volume is the product of these dimensions.

  V = LWH

  V = (x+2)(2x+2)(3x+2) = (x +2)(6x^2 +10x +4)

  V = 6x^3 +22x^2 +24x +8

The volume of the box is 6x^3 +22x^2 +24x +8.

Answer:

20

Step-by-step explanation:

To solve we must first find what 80% is in decimal form.

80% ---> 0.80

We can now multiply this decimal by 25

25 × 0.80 = 20

Dana gets paid $10 per hour plus a $10 bonus for the week. Tommy gets paid $9 per hour plus $13 bonus for the week. Set up a system of equations and tell how many hours they would need to work to earn the same amount.
A) 3 hours
B) 40 hours
C) 20 hours
D) 10 hours

Answers

Answer:

A) 3 hours

Step-by-step explanation:

x = per hour

y = total

Dana:

y = 10x + 10

Tommy:

y = 9x + 13

Combined (Solve for x):

y = 10x + 10

y = 9x + 13 (Multiply by -1)

y = 10x + 10

-y = -9x - 13

0 = x - 3

x = 3
