Answer:
160 ft^2
Step-by-step explanation:
First you have to find the width, then you find the area. To find the width with a percentage we do Part/ Total = %/100 and we cross multiply. We need to find the part so that is the unknown, we will call it 'w' for width
w/20 = 40/100 Now we cross multiply, the x and the 100 and the 20 and 40
w * 100 = 100w
20 * 40 = 800
Now we have 100w = 800 The next step is to divide both sides by 100 so we just have w
100x/100= w
800/100 = 8
w = 8
The width is 8
Now we find the area which is length x width
20 x 8 = 160
So the area is 160 ft^2
3) Paul bought 2 muffins, 2 brownies and I cookie at a bake sale. The muffins cost $1.30
each, the brownies cost $0.75 a piece and the cookie was $0.50. If he paid with a twenty
dollar bill, how much change should he get back?
Answer:
$15.40
Step-by-step explanation:
1.30 × 2 = 2.60
0.75 × 2 = 1.50
2.60 + 1.50 + 0.50 = 4.60
20 - 4.60 = 15.40

First, we need to figure out how much you want to borrow. You said you wanted to spend $5,000, and you will put $500 down. Based on that, we can estimate your taxes to be $340. Put those numbers to see how much money you will need for your loan.
Answer: You will need $4,160 for the loan.
The money that will need for the loan is $4160.
What is down payment?A down payment is a sum of money the buyer pays at the outset of a large transactions. The down payment represents a portion of the total purchase price, and the buyer will often take out a loan to finance the remainder.
For the given situation,
The total amount wanted to spend = $5000
Down payment = $500
Tax amount = $340
Money that will need for the loan can be calculated as
⇒ [tex]5000-(500+340)[/tex]
⇒ [tex]5000-840[/tex]
⇒ [tex]4160[/tex]
Hence we can conclude that the money that will need for the loan is $4160.

A chemist needs 500mL of 20% acid and 80% water mix for an experiment. He adds x mL of a 10% acid and 90% water and y mal of a 30% acid and 70% water mix to the 20% acid and 80% water mix. Find the amounts x and y
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

Ben is 12 years older than Ishaan.Ben and Ishaan first met two years ago.Three years ago,Ben was 4 times as old as Ishaan.
Ben is 19 and Ishaan is 7.
If 3 years ago Ben was 4 times the age of Ishann, their ages could have been any of the following:
1. Ben is 4 and Ishaan is 1
2. Ben is 8 and Ishaan is 2
3. Ben is 12 and Ishaan is 3
4. Ben is 16 and Ishaan is 4
And so on.
Next add 3 to both ages, to show current age.
1. Ben is 7 and Ishaan is 4
2. Ben is 11 and Ishaan is 5
3. Ben is 15 and Ishaan is 6
4. Ben is 19 and Ishaan is 7
Ben is currently 12 years older than Ishaan. To find the difference, take Ben's age and subtract Ishaan's age.
1. 7 - 4 = 3
2. 11 - 5 = 6
3. 15 - 6 = 9
4. 19 - 7 = 12
Thus meaning Ben is 19 and Ishaan is 7.

Find the value of x to the nearest tenth.
Answer:
16. The answer is 16.5
17. The answer is Sin33.1°
18. The answer is 38.2
Step-by-step explanation:
In rounding up figures, number 1 to 4 is rounded up to 0 while numbers 5 to 9 is rounded up to 1.
16. Two sides in the right angle triangle are involved, the opposite side and the adjacent side, hence we use the tangent.
Tan36°=12/x
Cross multiply
x(tan 36°)= 12
Divide both sides by tan36°
x= 12/tan36°
16.516583
Rounded to the nearest tenth, we have 1 as the digit hundredth, which will be rounded up to 0.
Added to the tenth digit, still remains 5.
Answer therefore is 16.5
17. Two affected sides here is the opposite side and hypothenus sid, hence we use the sine.
sin x=12/22
= 33.055°
The digit hundredth is 5, which is rounded up to 1. Added to the tenth digit, we have 0+1=1
Answer is 33.1
18. Two affected sides are the opposite side and hypothenus side, we also use the sine.
Sin58°=x/45
Make x the subject
x=45/sin58°
38.162
6 is the digit hundredth, and it is rounded up to 1. Adding 1 to 1, the tenth digit in the figure above, we have our answer as

A shoreline is eroding at a rate of 1/3 foot per 3 months. How many feet are eroding per year?
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

The circle is inscribed in triangle PRT. A circle is inscribed in triangle P R T. 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 R S is 5, the length of P U is 8, and the length of U T is 6. Which statements about the figure are true? Select two options. The perimeter of the triangle is 19 units. TU ≅ TS PU ≅ TU The length of line segment PR is 13 units. The length of line segment TR is 10 units.
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.

it take 96 pounds or seed to completely plant a 10-acre field. how many pounds of seed are needed per acre?
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.
Explanation: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.

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
