2. Henri and Talia are mixing paint for an art project. They mixed p liters of red paint,
0.6 liters of blue paint, and p-0.4 liters of white paint. They then divided the mixture
evenly into 2 jars. If each jar contains 2.4 liters of paint, how many liters of red paint did
they use? Type your numeric answer below.
Answer:
They used 2.3 liters of red paint
Step-by-step explanation:
Henri and Talia are mixing paint for an art project.
They mixed amount of red paint = p liters
They mixed amount of blue paint = 0.6 liters
They mixed amount of white paint = p-0.4 liters
Total amount of paint = p +0.6 +p - 0.4 = 2p+0.2
They then divided the mixture evenly into 2 jars.
Amount of paint in 1 jar = [tex]\frac{2p+0.2}{2}[/tex]
We are given that Each jar contains 2.4 liters of paint
So, [tex]\frac{2p+0.2}{2}=2.4[/tex]
[tex]2p+0.2=2.4 \times 2[/tex]
[tex]2p+0.2=4.8[/tex]
[tex]2p=4.8-0.2[/tex]
2p=4.6
[tex]p=\frac{4.6}{2}[/tex]
p=2.3
Hence They used 2.3 liters of red paint
The correct statement is the red paint they use is 2.3 liters.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
They mixed p liters of red paint, 0.6 liters of blue paint, and a p-0.4 liter of white paint.
They then divided the mixture evenly into 2 jars. If each jar contains 2.4 liters of paint.
How to find the red color in it?They mixed p liters of red paint, 0.6 liters of blue paint, and a p-0.4 liter of white paint. According to this, the total paint will be
The total paint in liters = p + 0.6 + p - 0.4
The total paint in liters = 2p + 0.2
They then divided the mixture evenly into 2 jars. If each jar contains 2.4 liters of paint. According to this,
[tex]\rm \dfrac{2p+0.2}{2} = 2.4[/tex]
On solving the equation, then p will be
[tex]\begin{aligned} \rm \dfrac{2p+0.2}{2} &= 2.4\\\rm 2p + 0.2 &= 4.8\\\rm 2p &= 4.6\\\rm p &= 2.3\end{aligned}[/tex]
Thus, 2.3 liters of red paint did they use.

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.

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.

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.

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

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

The sum of four times a first number and a second number is 68. If the first number is decreased by twice the second number the result is -1. Find the numbers.
The first number is 15 and the second number is 8.
Step-by-step explanation:
Let us assume,
First number be 'x'.Second number be 'y'.Given :
Sum of four times a first number and a second number is 68.
⇒ 4x + y = 68
⇒ y = 68-4x
If the first number is decreased by twice the second number the result is -1.
⇒ x - 2y = -1
Substitute y = 68-4x in the above equation.
⇒ x - 2(68-4x) = -1
⇒ x-136+8x = -1
⇒ 9x - 136 = -1
⇒ 9x = -1+136
⇒ x = 135/9
⇒ x = 15
The first number is 15.
The second number is y = 68-4x.
⇒ y = 68 - 4(15)
⇒ y = 68-60
⇒ y = 8
The second number is 8.

f(2) = 3([tex]2^{4}[/tex] ) - 12(2³) - 12(2²) + 30(2)
= 48 - 96 - 48 + 60 = - 36
f(3) = 3([tex]3^{4}[/tex] ) - 12(3³) - 12(3²) + 30(3)
= 243 - 324 - 108 + 90 = - 99

Given a polynomial with roots x = a, x = b, then
(x - a), (x - b) are the factors
and the polynomial is the product of the factors
Here the roots are x = - 2, x = - 1, x = 3 and x = 4, thus the factors are
(x + 2), (x + 1), (x - 3) and (x - 4)
The polynomial is the product of the factors, thus
f(x) = (x + 2)(x + 1)(x - 3)(x - 4) ← expand in pairs using FOIL
= (x² + 3x + 2)(x² - 7x + 12) ← distribute
= [tex]x^{4}[/tex] - 7x³ + 12x² + 3x³ - 21x² + 36x + 2x² - 14x + 24 ← collect like terms
= [tex]x^{4}[/tex] - 4x³ - 7x² + 22x + 24
