Step-by-step explanation:

here's your solution

=> in first figure , base = 5.5, perpendicular =7.8

=> h^2 = 5.5^2 + 7.8^2

=> h^2 = 30.25 + 60.84

=>h^2 = 91.09

=> h = √91.09

=> h = 9.5

 Both figure are congruent

enc we will get a rectangle by add both 

hope it helps

HELP ME PLEASE

yuradex [85]

Answer:

368 milliliters.

Step-by-step explanation:

Compound A + Compound B = 1 drug

4 + 7 = 1 drug

11 milliliters = 1 drug, so 1012 milliliters = 92 drugs

Multiply the compounds by the amount of drugs, e.g.

4 x 92 = 368 ( Compound A )

7 x 92 = 644 ( Compound B )

368 + 644 = 1012

368 milliliters of Compound A are needed to make 1012 milliliters of the drug.

Hope this helps :)

36/49 = 5/n find n. will mark for whoever answers

Crazy boy [7]

Answer:

n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

eliminate fractions by multiplying by the LCM of the denominators
divide by the coefficient of the variable.

Doing that, we have ...

(49n)(36/49) = (49n)(5/n)

36n = 49·5 = 245 . . . . . simplify

n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

49/36 = n/5

Now, all you need to do is multiply by 5.

n = 5(49/36) = 245/36

Or, you can do both of the original steps at the same time:

(49n/36)(36/49) = (49n/36)(5/n)

n = (49·5)/36 = 245/36
