Annette [7]
26' is 26 feet. There are 3 feet in a yard, so to find the number of yards in 26 feet, you can divide 26/3.

26/3 = 8 2/3

There are 8 2/3 yards in the 26' long painting.

A cyclist travels at 20 kilometers per hour when cycling uphill, 24 kilometers per hour when cycling on flat ground, and 30 kilo
Dvinal [7]

Answer:

Their average speed during the entire round trip = 24 miles per hour

Step-by-step explanation:

To determine:

What was their average speed during the entire round trip?

Information Fetching and Solution Steps:

  • A cyclist travels at 20 kilometers per hour when cycling uphill
  • 24 kilometers per hour when cycling on flat ground
  • 30 kilometers per hour when cycling downhill

On a sunny day, they cycle the hilly road from Aopslandia to Beast Island before turning around and cycling back to Aopslandia.

Let us assume that that the road is uphill one way and downhill the other way

As we know that the formula of average speed

Average\:speed=\:\frac{Total\:Distance\:\:Covered}{Total\:Time\:taken\:to\:cover\:the\:distance}\:\:

  • As\:they\:do\:an\:out\:and\:back\:trip

The\:up\:and\:down\:portions\:reverse\:and\:the\:flat\:remains\:the\:same

On the way out:

Say              

60\:miles\:up\:hill=\:3\:hours

flat\:48=\:2\:hrs

down\:120=4\:hrs

on the way back:

up\:120\:=\:6\:hrs

flat\:48=\:2\ hrs

down\:60=\:2\:hrs

So,

total\:miles\:=\:456\:miles

total\:time\:=\:19\:hrs\:\:\:

As

Average\:speed=\:\frac{Total\:Distance\:\:Covered}{Total\:Time\:taken\:to\:cover\:the\:distance}\:\:

Therefore,

Average\:speed=\:\frac{456}{19}\:\:\:

                        = 24 miles per hour

Hence, their average speed during the entire round trip = 24 miles per hour

2. Determine whether the relation is a function.
aev [14]

Answer:

yes It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

in triangle PQR the measure of angle R=90, QP=73, RQ=55, and PR=48. what is the value of the sine of angle P to the nearest Hund
alexandr402 [8]

Answer:

P ≈ 48.89°(nearest hundredth)

Step-by-step explanation:

The triangle PQR forms a right angle triangle since angle R is 90°. The triangle has an hypotenuse , adjacent and opposite side.

Using the SOHCAHTOA principle one can find the sine ratio of angle P. Let us designate where each side represent.

opposite side(QR) = 55

adjacent side(PR) = 48

hypotenuse(PQ) = 73

sin P = opposite/hypotenuse

sin P = 55/73

P = sin⁻¹ 55/73

P = sin⁻¹ 0.75342465753

P = 48.8879095605

P ≈ 48.89°(nearest hundredth)
