Divide £300 in a ratio of 3:7
Answers
it means you have to sum
Now you have to divide
Now multiplay
and
so £
2. Divide 300 by 10 = 30
3. Times 30 x 3 = 90
4. Times 30 x 7 = 210
90 + 210 = 300
your answer is 90 : 210

One pound is equivalent to 16 ounces.
Thus, multiply 14 pounds with 16 to get the number of ounces.
14 pounds equals 224 ounces. Let me know if you need any clarifications, thanks!

Answer:
224 ounces
Step-by-step explanation:
their are 16 ounces in a pound so you would do 14 times 16 to get 224

B.69ft

D.8.31ft
2. Which of these cannot represent the lengths of the sides of a right triangle?
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
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
256+3969=4225
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
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
