maksim [4K]

Answer:

A). PR = 16.13 ft

B). QR = 9.64 ft

Step-by-step explanation:

Part (A).

From the figure attached,

ΔPQR is a right triangle,

m(PQ) = 14 ft

m(QR) = 8 ft

By applying Pythagoras theorem,

Hypotenuse² = (Leg 1)² + (Leg 2)²

(PR)² = (PQ)² + (QR)²

(PR)² = (14)² + (8)²

PR = √260

     = 16.125

     ≈ 16.13 ft

Part (B).

If PR = 17 feet

and PQ = 14 feet

By applying Pythagoras theorem in ΔPQR,

PR² = PQ² + QR²

(17)² = (14)² + (QR)²

(QR)² = 289 - 196

QR = √93

     = 9.644

     ≈ 9.64 ft

Justin ran 15 miles at a constant rate in 2.5 hours. The next day, he ran at a rate that was 1 mph slower. What was Justin’s rat
finlep [7]
We can use the factor label method for this problem. The real hint to these types of equations are the units. In this case the units are in miles per hour for the rate.
15 miles/ 2.5 hours = 6mph or 6 miles/hours
If his rate was 1 mph slower we just subtract 1 from 6 mph
6mph - 1mph= 5 mph.

Hope this helps, good luck.

We know that when a die is rolled

There six possibilities

and two numbers are assigned to each

so, each are getting equal shares

so, this is fair

so, this is TRUE

(B)

There will be three names in three piece of paper

so, each having equal probability of getting front seat

so, this makes a fair decision

so, this is TRUE

(C)

We know that when a coin is flipped twice  , we can get same face again and again

It won't make equal probability for each one

so, it won't be fair for anyone

so, this is FALSE

(D)

We know that when a die is rolled , we can get same number again and again

It won't make equal probability for each one

so, it won't be fair for anyone

so, this is FALSE
