There are 16 girls and 12 boys which means the ratio of number of girls to the numbers of boys in her class is 16:12 and 4:3 when simplified.

2^2/5+ 3^1/10 <br> HELP ASAP

gizmo_the_mogwai [7]

Answer:

$\sqrt[5]{4}$ + $\sqrt[10]{3}$

Step-by-step explanation:

We sure can write 2^2/5+ 3^1/10 as $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$

// use the $a^{\frac{m}{n} } =\sqrt[n]{a^{m} }$ to transform the expression

Convert $2^{\frac{2}{5} }$ to $\sqrt[5]{2^{2} }$ = $\sqrt[5]{4}$ (here a = 2, n = 5, m = 2)

Then convert $3^{\frac{1}{10} }$ to $\sqrt[10]{3^{1} }$ = $\sqrt[10]{3}$ (here a = 3, n = 10, m = 1)

Now we get $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$ = $\sqrt[5]{4}$ + $\sqrt[10]{3}$ . This is the simplified form, which is the answer.

Hi I have no idea how to do this question :)

Answer:

A. 36

Step-by-step explanation:

Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other

if the area of a triangle is hb/2,

(with h=length of height, b=length of base)

the height of the first triangle is:

25 = 10h/2

50 = 10h

h=5

you can write ratios representing the proportions of the two triangles:

5/x = 10/12 (with x=height of second triangle)

x=6

then find the area of the second triangle with the height (6) and base (12)

(6*12)/2 = 36

<h3><u>Answer:</u></h3>

11. 6 + n = 20
12. n - 7 = 20
13. n + n + 1 = 31
14. 2n + 2 = 13
15. n - 1 = 18
16. n² + 4 = 2x
17. 2n = 1/2
18. n²/2 = 18
19. n/2 + 90/2 = 70
20. 2 + n = 12

Hoped this helped.
