Answer:

QT = 16

Step-by-step explanation:

ΔQRS ~ ΔQRT

In similar triangles, corresponding angles are in same ratio.

\frac{QS}{QR}=\frac{QR}{QT}\\\\\frac{25}{20}=\frac{20}{QT}

Cross multiply,

QT * 25 = 20 * 20

QT =\frac{20*20}{25}\\\\QT = 4*4\\\\QT = 16

One of the legs of a right triangle measures 6 cm and its hypotenuse measures 8 cm. Find the measure of the other leg. If necess
Vika [28.1K]
Well, this is a Pythagorean theorem problem. A^2 + B^2 = C^2, where C^2 is equal to the hypotenuse. 8 squared equals 64, so c^2 = 64 cm. The other leg can be represented by A^2, which is 36 cm. 36 + ? = 64. 64 - 36 = 28, so B^2 equals 28. Now, to find the measurement of the other leg, we need the square root of 28. The square root of 28 is 5.3 cm.

Your final answer is 5.3 cm.

The total cost of hiring paul the plumber is a function of the required number of hours needed to complete the repair. Paul char
DiKsa [7]

Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is

m = 75+40h

where m is the amount of money and h is the number of hours.

Since h can be at most 8, this is the case that generates the highest money, so if we plug h=8 we have

m = 75+40\cdot 8 = 75 + 320 = 395
