<span>A unit fraction is a fraction where the denominator is one, so the easiest way to write 4/5 as a sum of unit fractions is to use 1/5.
So the answer would be 1/5+1/5+1/5+1/5.
Add up all the numerators and put that over their like denominators to get 4/5!</span><span />

Answer:

\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}

Step-by-step explanation:

we know that

A <u>unit fraction</u> is a fraction with a numerator equal to 1

so

In this problem we have

\frac{4}{5}

rewrite as a sum of unit fractions

\frac{4}{5}=4*\frac{1}{5}=\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}

Si un cono lo obtienes haciendo girar un triángulo rectángulo cuya base es de 10cm y su altura es de 16cm ¿cuánto mide el radio
rodikova [14]

Answer:

10 cm.

Step-by-step explanation:

In order to better understand this question, I will attach an allusive image to the question.

Keep in mind that in this case the base of the triangle is equal to the radius of the base of the cone since the triangle rotates on its own axis, therefore the measurement of the base corresponds to 10 cm, therefore the radius measures 10 cm.

The length of each leg of an isosceles right triangle is 4 cm. What is the length of the hypotenuse
miss Akunina [59]

<u>Answer:</u>

5.65 cm

<u>Step-by-step explanation:</u>

We are given that the length of each leg of an isosceles right triangle is 4 cm and we are to find the length of the hypotenuse.

For this, we will use the Pythagoras Theorem:

a ^ 2 = b ^ 2 + c ^ 2

where a is the hypotenuse.

a ^ 2 = 4 ^ 2 + 4 ^ 2

\sqrt { a ^ 2} = \sqrt { 3 2 }

a = 5 . 6 5

Therefore, the length of the hypotenuse is 5.65 cm.

Elena is thinking about putting $200 in a savings account that earns 4% interest compounded semiannually. She wants to keep that
Nastasia [14]
I’m not 100% bc/ I learned this last semester, but I think it’s B. So sorry if I’m wrong. I think this bc/ 0.04 is the interest rate as a percent, 4 is the time, 200 is the amount of money, and the one shows that it is exponential growth.
