Answer: he was 84 years old when he died and the fractional part of a century that he live is 21/25
Step-by-step explanation:
General Douglas MacArthur, one of the leading generals in World War II was born in 1880. He died in 1964. The number of years that he lived would be the year he died - the yea he was born. Therefore,
His age when he died
= 1964 - 1880 = 84 years.
The number of years in a century is 100. Therefore, the fractional part of a century that he lived would be
84/100 = 21/25
Let a= number of apples and o= number of oranges.
because she wants the total number of fruit to be at least 20.
because each apple costs $0.24 and each orange is $0.80. She cannot spend more than $12.
Answer:
10 cm
Step-by-step explanation:
we know that the perimeter of a rectangle= 2(l+w)
given that the perimeter is 46 cm and length is 13 cm, so by putting the values we get,
2(13+w)=46
= 26+2w=46 (opening the brackets)
= 2w= 46-26
= 2w=20
= w=20/2
w= 10 cm

Answer:
MN = sqrt(34)
Step-by-step explanation:
First, draw the segment FN. The diagonal, MN, of the prism is the hypotenuse of triangle NFM. Triangle NFM is a right triangle with legs FN and FM and hypotenuse MN.
Leg FM of triangle NFM has length 4 cm.
We need to find the length of leg FN.
Look at the base of the prism which is square UNAF. FN is a diagonal of that square. Now think of right triangle FUN with legs UN and UF, each of length 3 cm. We can find FN with the Pythagorean theorem.
(UF)^2 + (UN)^2 = (FN)^2
3^2 + 3^2 = (FN)^2
(FN)^2 = 18
FN = sqrt(18)
Now we know FN. We use FN and FM as legs and find MN, the hypotenuse of triangle NFM.
(FN)^2 + (FM)^2 = (MN)^2
18 + 4^2 = (MN)^2
18 + 16 = (MN)^2
(MN)^2 = 34
MN = sqrt(34)
