Answer:

Your graph would look like lines going up and up and up

Step-by-step explanation:

Why you ask? Well, because the graph shown here is going by the factors of 6. And the factors of 6 are pretty high, which means it would be going up like a twisted line going right ot left depending which way you look at it. It would be going up and up because like 18 times 6 is 108 and 20 times 6 is 120.

The number of feet the shoreline is eroding per year is 1 ⅓ feet.

How many feet are eroding per year?

Rate of shoreline eroding per 3 months = 1/3 foot

Number of 3 months in a year = 12 months / 3 months

= 4

Number of feets of the shoreline eroding per year = Rate of shoreline eroding per 3 months × Number of 3 months in a year

= 1/3 × 4

= 4/3 feet per year

Therefore, the shoreline erodes 1⅓ feet per year

Answer:

40s units²

Step-by-step explanation:

Area of frame = area of bigger rectangle - area of smaller one

Area of big rectangle = length × breadth

= 12 × 6s = 72s unit²

Area of smaller rectangle = length x breadth

= 8 × 4s = 32s units²

Area of frame  = 72s -  32s

= 40s units²

Answer:

  x = y = 250 mL

Step-by-step explanation:

The desired concentration of acid (20%) is exactly halfway between the concentrations of the available supplies (10%, 30%). So, the mix will be equal parts of each of those. x and y are both half the total quantity required:

  x = y = (500 mL)/2 = 250 mL

_____

If you need an equation to solve this, you can let x = 500 -y and write the equation for the acid volume in the final mix:

  10%(500 -y) +30%(y) = 20%(500)

  50 -0.1y +0.3y = 100 . . . . . eliminate parentheses

  0.2y = 50 . . . . . . . . . . . . . . subtract 50, collect terms

  y = 250 . . . . . . . . . . . . . . . multiply by 5 (equivalently, divide by 0.2)

  x = 500 -250 = 250

Answer:

[tex]\sqrt[5]{15}[/tex]

Step-by-step explanation:

A number to 1/5 is the [tex]\sqrt[5]{n}[/tex]

A number to 1/3 is the [tex]\sqrt[3]{n}[/tex]

So, since the number is 15 to the 1/5, it is [tex]\sqrt[5]{15}[/tex]

Answer:  [tex]\sqrt[5]{15}[/tex]

Answer:

[tex]15^{\frac{1}{5} } = \sqrt[5]{15}[/tex]

Step-by-step explanation:

recall that

[tex]a^{\frac{1}{b} } = \sqrt[b]{a}[/tex]

if we apply this to our case,

[tex]15^{\frac{1}{5} } = \sqrt[5]{15}[/tex]

Answer:

Part A) [tex]A=1.25W^2[/tex]

Part B) Length: 17.5 feet and Width: 14 feet

Step-by-step explanation:

Part A) Create an equation to represent the area of the basketball section A, in terms of the width W.

Let

L ----> the length of the  rectangular basketball section

W ---> the width of the  rectangular basketball section

we know that

The area of the rectangular basketball section is equal to

[tex]A=LW[/tex] ----> equation A

The length of the section will be 1.25 times the width of the section

so

[tex]L=1.25W[/tex] ----> equation B

substitute equation B in equation A

[tex]A=(1.25W)W\\A=1.25W^2[/tex]

Part B) Jackson decides to make the area of the basketball section 245 square feet. What are the dimensions, in feet, of the basketball section?

we have

[tex]A=1.25W^2\\A=245\ ft^2[/tex]

so

[tex]245=1.25W^2[/tex]

solve for W

[tex]W^2=245/1.25\\W^2=196\\W=14\ ft[/tex]

Find the value of L

substitute the value of W in the equation B

[tex]L=1.25(14)=17.5\ ft[/tex]

therefore

The dimensions are :

Length: 17.5 feet

Width: 14 feet

The area equation for the basketball section is A = 1.25w². For an area of 245 square feet, the width, w, is approximately 14 feet, and the length, l, is approximately 17.5 feet.

Part A: Equation of the Area

To create an equation that represents the area, A, of the basketball section in terms of the width, w, we start with the fact that the length is 1.25 times the width. So, if l represents the length, then l = 1.25w. The area of a rectangle is found by multiplying the length by the width, hence the area A = l × w. Substituting l = 1.25w gives us the equation A = (1.25w) × w = 1.25w².

Part B: Dimensions of the Basketball Section

Given the area of the basketball section is 245 square feet, we can use the equation found in Part A to determine the width and subsequently the length. The equation A = 1.25w² becomes 245 = 1.25w². Solving for w, we take the square root of both sides after dividing by 1.25, which gives w = √(245/1.25) ≈ 14 feet. To find the length, l, we multiply the width by 1.25, resulting in l = 1.25 × 14 ≈ 17.5 feet. Therefore, the dimensions are approximately 14 feet in width and 17.5 feet in length.

Option B: [tex]TU $\cong$ TS PU $\cong$ TU[/tex]

Option C: The length of line segment PR is 13 units.

Explanation:

Given that the circle is inscribed in triangle PRT. Points Q, S, and U of the circle are on the sides of the triangle. Point Q is on side P R, point S is on side R T, and point U is on side P T.

The length of RS is 5, the length of PU is 8 and the length of UT is 6.

Option A: The perimeter of the triangle is 19 units.

The perimeter of the triangle is given by

Perimeter of ΔPRT = PU + UT + TS + SR + RQ + QP

Since, P, T and R are tangents to the circle and we know that "Tangents to a circle drawn to a point outside the circle are equal in length".

Thus, we have,

RS = RQ = 5

PU = PQ = 8 and

UT = TS = 6

Substituting the values in the perimeter of ΔPRT, we get,

Perimeter of ΔPRT = 8 + 6 + 6 + 5 + 5 + 8 =38 units

Thus, the perimeter of the triangle is 38 units.

Hence, Option A is not the correct answer.

Option B : [tex]TU $\cong$ TS PU $\cong$ TU[/tex]

Since, P, T and R are tangents to the circle and we know that "Tangents to a circle drawn to a point outside the circle are equal in length".

Then [tex]TU $\cong$ TS PU $\cong$ TU[/tex]

Hence, Option B is the correct answer.

Option C: The length of line segment PR is 13 units.

The length of PR is given by

PR = PQ + QR

Substituting the values RQ = 5 and PQ = 8, we get,

PR = 5 + 8 = 13 units

Thus, the length of line segment PR is 13 units.

Hence, Option C is the correct answer.

Option D: The length of line segment TR is 10 units.

The length of TR is given by

TR = TS + SR

Substituting the values TS = 6 and SR = 5, we get,

TR = 6 + 5 = 11 units

Thus, the length of line segment TR is 11 units

Hence, Option D is not the correct answer.

Step-by-step explanation:

Given that height is a quarter the sum of bases and that the height is 2.5ft.

The sum of bases is calculated as:

[tex]h=\frac{1}{4}\sum{b_i}=2.5\\\\\sum{b_i}=2.5\times 4\\\\\sum{b_i}=b_1+b_2=10\ ft[/tex]

#Having that (b1+b2=10 ft), we can now calculate the area using the given formula using the given figures:

[tex]A=\frac{1}{2}\times 2.5\times (b_1+b_2), b_1+b_2=10\\\\=\frac{1}{2}\times 2.5\times10\\\\=12.5[/tex]

Hence, the area of the trapezoid is 12.5 sq ft

*Using the h=2.5ft and the [tex]A=\frac{1}{2}h(b_1+b_2)[/tex]

Answer:

9.6 lb/acre

Step-by-step explanation:

This is a unit rate problem. You want to know the number of pounds used for one acre.

You divide 96 pounds by 10 acres to find the number of pounds per 1 acre.

(96 lb)/(10 acres) = 9.6 lb/acre

Answer: 9.6 lb/acre

To find how many pounds of seed are needed per acre, divide the total amount of seed used, which is 96 pounds, by the total area, 10 acres. The answer is 9.6 pounds per acre.

This problem is a simple division problem in Mathematics. We start by taking the total amount of seed that was used, which is 96 pounds. Then, we divide this by the total area, which in this case is 10 acres.

When we perform the calculation: 96 pounds ÷ 10 acres, the solution we get is 9.6 pounds per acre.

So, it requires 9.6 pounds of seed to plant one acre of the field. Remember, this is an average estimation. Actual seed requirement may vary depending on the type of seed and other factors such as soil and weather conditions.
