find QR. help please and thank you<3
Answer:
QR = 1.3
Step-by-step explanation:
Sides TQ and TS are congruent, thus Δ QST is isosceles.
RT is a perpendicular bisector, that is it bisects QS at right angles, thus
QR = RS = 1.3
The measure of length of QR is 1.3 units.
What is an isosceles triangle?Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.
In the given triangle TQS, QT=TS=4.7 units, so triangle TQS, isosceles triangle.
In isosceles triangle TQS, TR is the perpendicular bisector.
Then QR=RS= 1.3 units
Therefore, the measure of length of QR is 1.3 units.

The function fx) = 2x + 3x + 5, when evaluated, gives a value of 19. What is the function's input value?
OA 1
OB-1
О с 2
OD. -2
OE-3
The input value that gives an output of 19 is not listed in the answer choices. None of the options are correct.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
We can start by setting up the equation:
2x² + 3x + 5 = 19
Subtracting 19 from both sides:
2x² + 3x - 14 = 0
(2x - 7)(x + 2) = 0
Using the zero product property, we can solve for x:
2x - 7 = 0 or x + 2 = 0
2x = 7 or x = -2
x = 7/2 or x = -2
Therefore, the input value could be either 7/2 or -2.
The answer choices do not include 7/2, but we can check both input values to see which one gives an output of 19:
f(7/2) = 2(7/2)^²+ 3(7/2) + 5 = 19.25
f(-2) = 2(-2)² + 3(-2) + 5 = 3
Thus, the input value that gives an output of 19 is not listed in the answer choices.

Step-by-step explanation:
Faye borrowed $9600 at 8% per anum compound interest.
(a) Calculate the interest on the loan for the first year.
At the end of the last year,she repaid $4368.
(b) How much did she still owe at the beginning of the year?
(c)Calculate the interest on the remaining balance for the second year.
Answer:
(a) $768
Step-by-step explanation:
Faye borrowed $9600 at 8% interest compounded per annum.
Solution for question (a):
Amount accumulated is given by;
A = P(1 + [tex]\frac{r}{n}[/tex][tex])^{nt}[/tex]
Where A is the amount, P is the pricipal, r is the rate, n is the number of times in a year, and t is the number of years.
So the amount after one year was;
A = 9600(1 + [tex]\frac{8}{1 * 100}[/tex][tex])^{1 * 1}[/tex] = 9600 × 1.08 = 10368
Interest = Amount - Principal = $10368 - $9600 = $768
a. The interest on the loan for the first year is $768.
b. The amount she still owe at the beginning of the year is $6,000.
c. The interest on the remaining balance for the second year is $480.
a. Interest on loan:
Interest on loan=$9600 × 8%
Interest on loan=$768
b. Amount owed
Amount owed=$9,600+$768-$4368
Amount owed=$6,000
c. Interest on remaining balance :
Interest on remaining balance=$6,000×8%
Interest on remaining balance=$480
Inconclusion the interest is $768, amount owe is $6,000 and Interest on remaining balance is $480.

At a swimming pool the ratio of those wearing sunscreen to those not wearing sunscreen was 7 to 5. If the number of people not wearing sunscreen was 30, then how many people were wearing sunscreen?
Answer:
42 people are wearing sunscreen
Step-by-step explanation:
Step one:
given data
We are given that the ratio of those wearing sunscreen to those not wearing sunscreen was 7 to 5.
i.e 7:5
number of people not wearing sunscreen is 30
let us use part to part method to solve this problem
let the number of people wearing sunscreen be x
so,
7/5= x/30
cross multiply we have
5x=210
divide both sides by 5
x= 210/5
x=42 people are wearing sunscreen
Answer:
I think the answer is 42 to 30. 42 kids wearing sunscreen and 30 kids were not. 30 divided by 5 is 6. 6 x 5 is 30. so 6 x 7 is 42. Hence 42 to 30. :)

Triangle ABC and triangle EDF
The similar triangles are Δ ABC ~ Δ EDF ~ Δ GHI, both the triangles are similar to Δ ABC.
What are similar triangles?Triangles are similar when their corresponding sides are equal ratios and their corresponding angles are congruent.
Given are triangles, Δ ABC, Δ EDF and Δ GHI,
Since, in Δ ABC and Δ EDF, two angles are shown congruent therefore, both are similar.
Also,
In Δ GHI,
∠ G + ∠ I = 129°
∠ H = 180° - 129°
∠ H = 43°
Since, we get, two angles congruent in both triangles Δ EDF and Δ GHI
Therefore, both the triangles Δ EDF and Δ GHI are similar,
Now,
Since, Δ ABC ~ Δ EDF and Δ EDF ~ Δ GHI,
Therefore, Δ ABC ~ Δ EDF ~ Δ GHI,
Hence, the correct option is "Both"

Question 7: Company A has a lower rate
Question 8: Caiden's vehicle gets more miles per gallon
Step-by-step explanation:
Question 7:
According to the table for Company B's rates, if you divide the total cost by the square footage in each row, you would get $2.75/ft² each time. Therefore, Company A would charge the Smiths a lower cost per square foot.
$2.25/ft² < $2.75/ft²
Company A < Company B
Question 8:
Using the given equation, we already know that Caiden's vehicle has a gas mileage of 16.2 miles/gallon The graph for Ethan's gas mileage can be figured out using slope. Taking the points (0, 0) and (2, 30) on the line, we can figure out the line's slope.
slope = rise/run,
where "rise" is how much you add or subtract to get from the first y-value to the second, and "run" is how much you add or subtract to get from the first x-value to the second.
slope = rise/run
slope = 30/2
slope = 15/1
The slope of the line is 15, so that means the line's equation is y = 15x. Therefore, Ethan's gas mileage is 15 miles/gallon.
16.2 mpg > 15 mpg
Caiden > Ethan

If you fill in the x and the y with the equation you have below, you would get:
-4 = 17(3)+b
Multiply 17 and 3
-4 = 51 + b

The volumes of two cylindrical cans of the same shape vary directly as the cubes of their radii. If a can with a six-inch radius holds 1½ pints, how many gallons will a similar can with a 24-inch radius hold?
Answer:
The second similar can with a radius of 24-inch radius will hold 12 gallons
Step-by-step explanation:
The given parameters are;
The volumes of the cylindrical can ∝ (The radius of the cans)³
The volume of first can, V₁ = 1¹/₂ pints
The radius of the first can, r₁ = 6-inch
The radius of the second can, r₂ = 24-inch
Therefore, we have;
V ∝ r³
V = k × r³
∴ 1¹/₂ pints ∝ (6 in.)³
1¹/₂ pints = 43.3125 in³
∴ 43.3125 in³ = k × 216 in.³
The constant of proportionality, k = 43.3125/216 = 0.2005208333
Therefore, we have for the second can, we have;
V₂ = k × r₂³ = 43.3125/216 × (24 in.)³ = 2772 in.³
The volume of the second can = 2772 in.³
1 in.³ = 0.004329 gallons
∴ 2772 in.³ = 2772 × 0.004329 gallons = 12 gallons
Therefore, the volume the second similar can with a 24-inch radius will hold = 12 gallons.

Angles in a triangle adds up to 180 degrees
so 105 + (6x+20) + (7x-10) = 180
simplify
115+13x=180
subtract 115 to each side
13x=65
divide by 13
x=5

105 + (6(5) + 20) + (7(5) -10)
105 + (30 +20) +(35 - 10)
