Answer:

3060 cm^2

Step-by-step explanation:

First, let's find the areas of the trapezoids.

  • \frac{34+6}{2}*15
  • 40/2 * 15
  • 20*15
  • 300 * 2  
  • 600

Next, let's find the area of the bases (the top rectangle and bottom rectangle).

  • Top: 6 × 30 = 180
  • Bottom: 34 × 30 = 1020
  • 1020 + 180 = 1200.

After that, we find the surface area of the side rectangles.

  • 17 × 30 = 510
  • 25 × 30 = 750
  • 510 + 750 = 1260.

Lastly, we add 1260, 1200, and 300 together.

  • 1260+1200+600
  • 3060

Therefore, the surface area should be 3060 cm^2.

Answer:

$135.01

Step-by-step explanation:

A mark up of 100% means that the price was doubled.

58.7*2=117.4

To add sales tax to a price (p) you need to do p+(sales tax * p)

117.4+.15(117.4)

HELP ME PLEASE!!! I AM GIVING BRAINLIEST TO WHO CAN SOLVE IT CORRECT
yaroslaw [1]

Answer:

x^2 +4x+4 = 4

Step-by-step explanation:

To complete the square  take the coefficient of the x term

4

Divide by 2

4/2 =2

Square it

2^2 =4

Add it to both sides of the equation

x^2 +4x+4 = 4

After years of overhunting, environmental scientists have reintroduced mountain goats into Yellowstone National Park. The initia
Tatiana [17]

We want to see how much the population of goats grows each year. We will see that the correct option is c: 17%.

<h3>Exponential growth of populations</h3>

We know that:

  • The initial number of goats is 1,500.
  • After 11 years, the population is 8,400.

The population can be modeled with an exponential equation as:

P(t) = A*(1 + r)^t

Where:

  • A is the initial population.
  • r is what we want to find, it depends on how much the population increases.
  • t is the time in years.

So we have:

P(t) = 1500*(1 + r)^t

And we know that after 11 years the population is 8,400, so we have:

P(11) = 1500*(1 + r)^11 = 8400

Now we can solve this for r:

(1 + r)^11 = 8400/1500 = 5.6

(1 + r) = (5.6)^(1/11) = 1.17

r = 1.17 - 1 = 0.17

r = 0.17

To get it in percentage form, you just need to multiply it by 100%

0.17*100% = 17%

This means that the population increases a 17% each year, so the correct option is c.

If B = -p + 10p2 and C = 2p + 7, find an expression that equals B + 3C in<br> standard form.
yuradex [85]

Answer:

10p^2 + 5p + 42 = b+3c

Step-by-step explanation:

b = -p + 10p^2

c = 2p + 7

b + 3c = 5p + 10p^2+ 42
