Answer:

5, 7, and 12

Step-by-step explanation:

First we can make and equation

x + z + y = 24

we can plug in the numbers you gave us giving us

y = x + z

z = y - x

x = (y - 2) ÷ 2

Once, were done we get that x = 5 ≈ smallest number

z = 7 ≈ second largest number

y = 12 ≈ largest number

iragen [17]

Answer:

D. 2 (1/3) hours

Step-by-step explanation:

'Of' means multiplication, so we are going to multiply

3 (1/2) x (2/3) = 2 (1/3)

or

3.5 x 0.66 = 2.333

I hope this helps!

I need help :( can anyone tell me the answer with a explanation?
Bond [772]

Let's say the test is 100 points.

The 70% mean means that the mean for the 30 students was 70 points.  That means 2100 points were scored between all 30 students. (70·30=2100)

 

20 boys had a mean of 62% or 62 points for our test.  That means the boys earned 62·20 points, or 1240 points.

 

That then means the girls earned 2100 - 1240 points, or 860 points.

Since there are 10 girls, 860/10 = 86 or 86% mean on the test.

 

Girls rock!

In a 30° -60° -90° triangle, what is the length of the hypotenuse when the shorter leg is 7 in.?
soldi70 [24.7K]

Answer:

the length of the hypotenuse is 14 in

Step-by-step explanation:

Focus on the 30 degree angle.  Recall that the sine of an angle is defined as

             opposite side        

sin Ф = ----------------------

                hypotenuse  

and that sin 30° is always 1/2.

                                7 in                               1

Then sin 30° = ------------------- must equal -----      

                         hypotenuse                        2

After cross-multiplying this equation, we have 2(7 in) = (1)(hypotenuse),

so that the length of the hypotenuse is 14 in.
