What is the length of side PR?
A. 8 cm
B. 11 cm
C. V105 cm
D. V176 cm
E. V274 cm
Answers
Answer:
D. √176 cm
Step-by-step explanation:
Were given a right triangle.
PQ = 7 cm
QR = 15 cm
To find the length of side PR, apply Pythagorean theorem, which is c² = a² + b²
Where,
c = hypotenuse/longest side = 15 cm
a = PR
b = 7 cm
Thus:
15² = PR² + 7²
225 = PR² + 49
225 - 49 = PR²
176 = PR²
√176 = PR
PR = √176 cm

o It cannot be determined from the information given
Answers
Answer:
I don't know
Step-by-step explanation:
the answer is 0.2
The average of x and y is 03
How to determine the average?The average of the three numbers is given as:
Average = 10
This means that:
(x + y + 24)/3 = 10
Multiply both sides by 3
x + y + 24 = 30
Subtract 24 from both sides
x + y = 6
Divide by 2
(x + y) = 3
Hence, the average of x and y is 03

Amount of calcium per day needed = 3 gram
Amount of calcium in a tablet = 300 mg
Find:
Number of tablet needed
Computation:
Number of tablet needed = Amount of calcium per day needed / Amount of calcium in a tablet

A 40 g ball of yarn is 125 m long. What is the mass of a ball of the same yarn that is 2 km long?
Answers
Answer:
640g
Step-by-step explanation:
1000m=1km so 125m times x= 2km x is 16 so we multiply 16 by 40 to get 640 g
The mass of 2 km long yarn ball is 640.
What is mass?A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter.
Given
40 g ball of yarn is 125 m long
To find mass for 2 km = 2000 m long yarn
[tex]\frac{40}{125} \ 2000[/tex] = [tex]\frac{80000}{125}[/tex] = 640g
Hence, The mass of 2 km long yarn ball is 640.
