What is the supplement of 122 degrees ​
Likurg_2 [28]

Answer:

The other angle is 58 degrees

Step-by-step explanation:

Supplementary angles add to 180 degrees

Let the other angle be x

x+122 = 180

Subtract 122 from each side

x+122-122= 180-122

x = 58

The other angle is 58 degrees

The selling price of an apartment dropped from 250,000 to 225,000. By What percent did the price drop?
ch4aika [34]

Answer:

10%

Step-by-step explanation:

The percentage decrease in price = \frac{decrease amount}{original amount} x 100%

Original amount = 250,000

New amount = 225,000

Decrease in amount = 250,000 - 225,000

                        = 25,000

So that;

Percentage decrease in price = \frac{25000}{250000} x 100%

                                           = 0.1 x 100%

Percentage decrease in price = 10%

The price of the apartment dropped by 10% of its original price.

11. The doubling time of a population of plants is 12 years. Assuming that the initial population is 300 and that the rate of in
Anastasy [175]

Answer:

The population will be of 2400 in 36 years.

Step-by-step explanation:

The equation for the population of plants after t years follows the following format:

P(t) = P(0)(1+r)^{t}

In which P(0) is the initial amount of plants and r is the yearly rate which it increases.

Assuming that the initial population is 300

This means that P(0) = 300.

The doubling time of a population of plants is 12 years.

This means that P(12) = 2*300 = 600.

We use this to find r.

P(t) = P(0)(1+r)^{t}

600 = 300(1+r)^{t}

(1+r)^{12} = 2

\sqrt[12]{(1+r)^{12})} = \sqrt[12]{2}

1 + r = 1.05946

So

P(t) = 300(1.05946)^{t}

How large will the population be in 36 years

This is P(36)

P(t) = 300(1.05946)^{36} = 2400

The population will be of 2400 in 36 years.

Lynna [10]

Answer:

surface are: 300 cm2

volume: 450cm3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Surface area of a box = 2wl + 2hw + 2 lh

Where w is the width of the box, l is the length of the box, and h is the height of the box.

The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.

S = wl + 2hw + 2 lh

Replacing with the values given:

S = (15x10)+ 2(3x10)+ 2(15x3)

S = 150+60+90=300 cm2

For the volume we simply apply:

Volume of a rectangular prism: length x width x height

V = 15x10x3 = 450cm3

Feel free to ask for more if needed or if you did not understand something.
