A.3 ft,4 ft,5 ft
B.6 in,8 in,10 in
C.16 cm,63 cm,65 cm
D.8 m,9 m,10 m

Answers

1.

so remember
a^2+b^2=c^2

a and b are the legs
c=hypotonuse so
a=24
b=45
subsitute
24^2+45^2=c^2
576+2025=c^2
2601=c^2
square root both sides
51=c

the answer is A. 51 ft

2. just subsitute and solve for ones that are not equal (hypotonuse is greater than either legs)
A. 3^2+4^2=5^2
9+16=25
25=25
correrct

B. 6,8,10
this is a multiplule of the 3,4,5 previoius so this works as well

C.16^2+63^2+65^2

4225=4225
correct

D. 8^2+9^2=10^2
64+81=100
145=100
false

the answer is D

ANSWERS:
1. A, 51 ft
2. D, 8,9,10

The answer is A).51 ft
To solve the problem use the Pythagorean Theorem. There are 3 parts to the Pythagorean Theorem. A (squared)+ B (squared) = C(squared). To "square" a number mutiply to itself. A=24
B=45, C is the Hypotenuse, you want to find out C. A is 24, a leg. B is 45, a leg. A squared is 24*24, 576 feet. B squared is 45*45, 2025 feet. To find C (the hypotenuse), add 576+2025 which is 2601 feet. The answer is **2601 feet**. Sometimes they will only give you 1 leg and the hypotenuse and want you to find the 2nd leg answer.
An example is if they asked " a right triangle has a 24 ft leg and hypotenuse is 2,601 ft. What is the length of the other leg? Still use Pythagorean Theorem. A is 24 ft,
you are looking for B,
you know that C is 2601 ft. So it is (24*24) +X squared=2601 ft. Then
2601-576. The answer is 2025, press square root button and it is 45 ft

plz help Pru, Piper, and Phoebe share spices in the ratio 5:3:4. If Pru has 24 more spices than Piper, how many spices does Phoebe have?

Answers

Answer:

48 spices

Step-by-step explanation:

The number of spices each has is a multiple of 5, 3, and 4.

The number of spices each has is 5x, 3x, and 4x.

Pru has 5x spices.

Piper has 3x spices.

Pru has 24 more spices than Piper, so

5x = 3x + 24

2x = 24

x = 12

Phoebe has 4x spices, so Phoebe has

4(12) = 48

Answer:

Step-by-step explanation: Pru, Piper, Phoebe their ratio 5:3:4 added = 12

What this would mean is that Pru has 5/12 of the total amount, Piper has 3/12 of the total, and Phoebe has 4/12 of the total amount of spices all together.

pru = piper + 24

5/12x = 3/12x + 24

5/12x - 3/12x = 24

2/12x = 24

x = 24 / (1/6)

x = 24 * 6

x = 144 spices in all.

Pru has : 5/12(144) = 720/12 = 60 spices

Piper has : 3/12(144) = 432/12 = 36 spices

Phoebe has : 4/12(144) = 576/12 = 48 spices <====
