A lot for sale is shaped like a trapezoid. The bases of the trapezoid represent the widths of the front and back yards. The widt

h of the back yard is twice the width of the front yard. The distance from the front yard to the backyard, or the height of the trapezoid, is equal to the width of the back yard. Find the width of the front and back yards, given that the area is 6000 square feet. Round to the nearest foot.

Answer

Front yard is 20 square root 5 back yard and height is 40 square root 5

Step-by-step explanation:

1. set up A=1/2 H(b1+b2)

2. 6000=1/2 2x (2x+x)

3. 12000=6x^2

4.2000 = x^2

5. x=20 square root 5

the population of collin county, which follows the exponential growth model, increased from 491,675 in 2000 to 782,341 in 2010.
CaHeK987 [17]

Applying the formula for the exponential growth model, the growth rate is  0.046447277776453351798354258063923

the exponential growth is a data pattern that illustrates an increase over time by generating an exponential function curve.

The exponential growth model can be expressed as:

P(t) = P(0) x e^(k.t)

Where:

P(t) = Value at time t

P(0) = Initial value

k = growth rate

Information from the problem:

P(0) = 491,675

P(t) = 782,341

t = 2010 - 2000 = 10 years

Substitute the data into the formula:

782,341 = 491,675 x e^{10k}

e^{10k} = 782,341 / 491,675

10 k . ln e = ln (782,341 / 491,675)

10 k = 0.46447277776453351798354258063923

k = 0.046447277776453351798354258063923

Tonya has a 1-quart, a 2-quart, and a 3-quart bowl. A recipe asks for 16 ounces of milk. If Tonya is going to triple the recipe,
Shalnov [3]
The answer would be the three quart bowl.Since it is clearly stated at the problem that if she 'triples' the recipe.So meaning, she needs to multiply each by three.So 1 quart = 3 quarts2 quarts = 6 quarts3 quarts = 9 quarts
So the smallest now would be the three quarts bowl.

Anon25 [30]

245/8.2 = 416/x
245x = 3411.2
x = 13.9
So the answer is 13.9 gallons
