Answer:
$225 of birthday money
Step-by-step explanation:
he spent 20 percent (1/5) of the money on dog treats, and the remaining 80 percent (4/5) went to 3 different charities. If $60 dollars were given to each charity, that means a total of $180 dollars was given to charity. if 4/5 of the money is equal to $180, we can divide 180 by 4 to get $45 dollars. this means that 1/5 of the birthday money would be equal to $45 dollars. so to find 5/5, or 100% of the money, simply multiply $45 by the denominator, 5, to get the answer. the total birthday money received was $225 dollars, and $45 dollars of that was used for dog treats.
The amount of money Mr. Thompson received for his birthday, work backwards from how much he donated to charities after spending 1/5 on dog treats, resulting in $300.
To find out how much money Mr. Thompson received for his birthday, we will work backwards from the information given.
Let's assume he received x amount of money for his birthday.
He spent 1/5 of it on dog treats, so he spent (1/5)x on dog treats.
The remainder after buying the dog treats is (4/5)x.
Since he divided this among 3 charities, each charity received $60, so [tex](\frac{4}{5} )x = 3*60.[/tex]
Solving this equation, we find x = $300.
Hence, Mr. Thompson received $300 for his birthday.

Step-by-step explanation:
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
38.2

Answer:
[tex]12.5 \ ft^2[/tex]
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]

HELP! PLEASE! Jackson is building a small rectangular basketball section in his backyard. The length of the section will be 1.25 times the width of the section.
Part A
Create an equation to represent the area of the basketball section, A, in terms of the width, w.
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?
SHOW ALL WORK PLEASE
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.
Explanation: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.
Which is the best step to do next to solve the equation by
completing the square?
The first few steps in solving the quadratic equation 5x2 +
27x = 14 - 13x by completing the square are shown.
5x2 + 27x = 14 - 13x
5x2 + 40x = 14
5(x2 + 8x) = 14
5(x2 + 8x + 16) = 30
5(x2 + 8x + 16) = 94
5(x2 + 8x + 4) = 18
5(x2 + 8x + 4) = 34
Answer:The correct answer among the choices given is option 2.
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
5x^2 + 27x + 13x = 14
5x^2 + 40x = 14
2. Make sure that the coefficient of the x^2 term is 1.
5(x^2 + 8x) = 14
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
5(x^2 + 8x + 16) = 14 + 80
5(x+4)^2=94
Step-by-step explanation:
The correct step is 5x2 + 40x = 14.

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.

Step-by-step explanation:
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
y = 250 . . . . . . . . . . . . . . . multiply by 5 (equivalently, divide by 0.2)
x = 500 -250 = 250
