Haley's clothing store sold 540 shirts with the ratio o f short sleeve to long sleeve being 3:9. how many short sleeve were sold

Answer: The hypotenuse are both 13 cm

Step-by-step explanation:

The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

So, in this case:

c^2 = a^2 + b^2

c^2 = 5^2 + 12^2

c^2 = 25 + 144

c^2 = 169

c = √169

c = 13

So the length of the hypotenuse is 13 cm.

Next, we can use the Pythagorean theorem to find the length of the segments into which the bisector of the right angle divides the hypotenuse. Let's call the length of the segments x. Then, the segments form two right triangles with legs of length x and (13-x)/2.

Using the Pythagorean theorem on each triangle, we have:

x^2 + ((13-x)/2)^2 = 13^2

x^2 + (13-x)^2/4 = 169

x^2 + (13^2 - 2x(13) + x^2)/4 = 169

x^2 + (13^2 - 2x(13))/4 = 169

x^2 + (169 - 26x)/4 = 169

x^2 + 169 - 26x = 676

x^2 - 26x + 507 = 0

Now, we can use the quadratic formula to find x:

x = (-b ± √(b^2 - 4ac)) / 2a

a = 1, b = -26, c = 507

x = (26 ± √(26^2 - 4 * 1 * 507)) / 2 * 1

x = (26 ± √(676)) / 2

x = (26 ± 26) / 2

x = 26 / 2

x = 13

So, the lengths of the segments into which the bisector of the right angle divides the hypotenuse are both 13 cm, to the nearest tenth.

The number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.

Revenue Passenger Miles (RPM) is a measure of how much passenger traffic an airline is serving, and is calculated by multiplying the number of revenue passengers (passengers paying a fare) by the distance travelled in miles. For this flight, the number of RPM is calculated as follows:

RPM = (Number of Revenue Passengers) x (Distance Travelled in Miles)

RPM = (285 Passengers) x (7,536 Miles)

RPM = 2,150,960 Miles

Therefore, the number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.

The value of q is -106 and the required equation is given by q=-106

In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions.

Given here: The statement of an equation" 336 is 230 decreased by q"

230 is decreased by q is equivalent to 230 substracted by q and the number obtained by the above operation is equal to 336

Thus we have the equation as follows

230-q=336

q=230-336

q=-106

Hence, The value of q is -106 and the required equation is given by q=-106

The triangles ∆DEF and ∆DGF are isosceles triangles, and the values of the following lengths are: EF = 44, FG = 36, and DF = 62.

EH is a perpendicular bisector of FD implies triangle ∆DGF is an isosceles triangle so:

FE is equal to ED and FG is equal to GD

7x + 9 = 9x - 1

9x + 7x = 9 + 1 {collect like terms}

2x = 10

x = 10/5 {divide through by 5}

x = 2

7y + 8 = 10y - 4

10y - 7y = 8 + 4 {collect like terms}

3y = 12

y = 12/3 {divide through by 3}

y = 4

EF = 7(5) + 9 = 44

FG = 7(4) + 8 = 36

DF = 2(FH)

FH = 3(5) + 4(4) = 31

DF = 2(31) = 62.

Therefore, the isosceles triangles ∆DEF and ∆DGF have the values of the following lengths as: EF = 44, FG = 36, and DF = 62.

The type of transaction described in the problem is called an installment purchase.

What is the simple interest?

Simple interest is a type of interest that is calculated on the principal amount of a loan or investment for a specific period of time.

The type of transaction described in the problem is called an installment purchase. In this type of transaction, a buyer pays a deposit at the time of purchase and then makes periodic payments, typically over a fixed period of time, until the full purchase price is paid off. In this case, the buyer pays a deposit of R999 and then pays off the remaining balance over a period of 3 years using simple interest.

To calculate the total amount that the buyer will pay over the 3-year period, we need to calculate the amount of interest that will be charged on the remaining balance. Since simple interest is being used, we can use the formula I = Prt, where I is the interest, P is the principal (the remaining balance), r is the interest rate, and t is the time period.

Assuming an annual interest rate of, for example, 5%, the interest charged on the remaining balance of R4000 (the original price minus the deposit) over 3 years would be:

I = Prt

I = 4000 * 0.05 * 3

I = R600

So the total amount that the buyer will pay over the 3-year period is:

R999 (deposit) + R4000 (remaining balance) + R600 (interest) = R5599

the total cost of the binoculars over the 3-year period will be R5599.

Hence, The type of transaction described in the problem is called an installment purchase.

(a) The red line is the middle line and goes through 1 data point, with 3 data points above it and 4 data points below it. This line has a slope that is between the slopes of the other two lines. However, it doesn't go through many of the data points and the slope is not consistent with the majority of the data points.

(b) The green line is the top line and touches 3 of the data points, with the rest of the data points below it. This line has a steeper slope compared to the red line, but it doesn't touch many of the data points and has a significant deviation from the majority of the data points.

(c) The blue line is the bottom line and has 2 data points below it and 6 data points above it. This line has a slope that is more consistent with the majority of the data points, and it has the least deviation from the data points compared to the other two lines.
