The Hogan family plans to build a rectangular house corral on their farm with length, L, and width,w. The area needs to be at least 1,900 ft 2 and have a width, w, of 20 ft.

What are the possible lengths, L, of the Hogans' house corral in feet?

Need help asap.

Answers

Answer: The length must be at least 95 ft. squared. Pick the line with the filled in left circle, and the right side is an arrow. Put the left side that's filled in on 95 (middle line between 90 and 100).

Step-by-step explanation: Divide the minimum total area by the minimum width. The answer is the minimum length.

Length x Width = Area

20 ft. x 95 ft. = 1900 ft. sq

The exponential equation is y = -2×(1/2)^x

Step-by-step explanation:

1) The horizontal asymptote of the function is the x axis (always nice)

2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)

3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:

Sue saved $360. She spent 75% of her savings. How much does she have left

Answers

Answer:

Step-by-step explanation:

Expense = 75%

Percentage of amount left = (100 -75)% = 25%

25% of 360 = 0.25* 360 = 90

Remaining amount left with Sue = $ 90

She would only have 25% remaining so 25% times 360 is $90

[tex]92\ yd^2[/tex]

Step-by-step explanation:

The given figure is a trapezoid, the formula for finding the area of a trapezoid is the following,

[tex]A=\frac{h(b_1+b_2)}{2}[/tex]

Where (h) is the height of the figure, and ([tex]b_1[/tex]) and ([tex]b_2[/tex]) are the bases. It is given that the height is (8) and ([tex]b_1[/tex]) is (8). The value of ([tex]b_2[/tex]) can be found by adding the value of ([tex]b_1[/tex]) to the "overhang" that ([tex]b_2[/tex]) has over ([tex]b_1[/tex]). Thus, ([tex]b_2[/tex]) is ([tex]8+7[/tex]) or rather ([tex]15[/tex]). Now substitute the values into the equation and solve for the area of the trapezoid,

[tex]A=\frac{8(8+15)}{2}[/tex]

[tex]=\frac{8(23)}{2}[/tex]

[tex]=4(23)[/tex]

[tex]=92[/tex]

Find the area of the semicircle. Round your answer to the nearest hundredth.

Answers

Answer:

56.52

Step-by-step explanation:

This is because in order to find an area of a circle you must do R^2*3.14 and since it is a semicircle add /2 so R^2*3.14/2 and since half of 12 is 6, 6*6 is 36 and 36*3.14 is 113.04 and divide that by 2 which is 56.52

Answer:

177.475 [tex]inches^{2}[/tex]

Step-by-step explanation:

Since the formula for finding the area of a full circle is A = π[tex]r^{2}[/tex], area equals pi times radius squared, we fill out the formula and solve.

A: unknown

Pi: 3.14

Radius: diameter is 12, so you divide it by 2, which is 6.

A = 3.14 x 6 squared.

using pemdas, you do exponents first,

A = 3.14 x 36

A ≈ 113.04

Now that we have the area for the full circle, we divide it by two to find the area of the semicircle,

113.04/2

= 56.52

So, the area of the semicircle is 56.52 [tex]inches^{2}[/tex]
