Can someone please awnser this for me i need to get a b in this class!!!!
Snezhnost [94]

The answer would be 30%

Explanation~

Well, you would have to add 27 and 23 first since, it says, “What percentage of the twelfth grade students have more than one college in mind” then, you’d have to figure out the percentage from there. And the percentage would be, 29.4117647059% of 170, round that to the nearest percent and it’s 30 I’m pretty sure.

Work out size of angle x
myrzilka [38]

Answer:

Step-by-step explanation:

Comment

You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle

Equation

Cos(x) = a/c the way you have labeled it.

Givens

a = 9

c = 18

Solution

Cos(x) = a / c

Cos(x) = 9 / 18

cos(x) = 1/2

x = cos-1(1/2)

x = 60 degrees

Answer

x = 60

Solve the equation. 3/4(2a-6)+1/2=2/5(3a+20)
Varvara68 [4.7K]

Answer:

a = 40

Step-by-step explanation:

This is a multi-step equation using the distributive property and rational coefficents (fractions).  The first step is to complete the distributive property on both sides of the equation and multiply each term in the expression in parenthesis by the constant on the outside.  (3/4 x 2a) - (3/4 x 6) +1/2 = (2/5 x 3a) + (2/5 x 20).  When we multiply and simplify, we get 3/2a - 9/2 + 1/2 = 6/5a + 8.  Next step is to combine like terms:  3/2a  - 8/2 = 6/5a +8.  We then need to isolate the variable by using inverse operations:  3/10a = 12, then solve for 'a' by multiplying both sides by the reciprocal (10/3) to get a = 40.
