Answer:

umm, a=3 I believe?

Step-by-step explanation:

4²=16, and 5²=25 so 25-16=9 and the square root of 9 is 3

Answer:

a = 3

Step-by-step explanation:

a^2 + 4^2 = 5^2

Step 1 square all exponents

a^2 + 16 = 25     4*4 = 16 and 5*5 = 25

Step 2 subtract 16 from both sides

a^2 +16 = 25

      -16    -16

a^2 = 9

Step 3 square root both sides

a = 3       square root of 9 is 3

Hope I helped!!

Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?
sergeinik [125]
Shaded circles = 4
Total circles = 12

\frac{shaded~circles}{total~circles} = \frac{4}{12}

\frac{4}{12} as a simplified expression = \frac{2}{6}
We can simplify it even more = \frac{1}{3}

Fraction = \frac{1}{3}

Equivalent decimal = 1 ÷ 3 = 0.33

The biggest among three numbers is 2.4 larger than the smallest one. If 15 times the smallest one is equal to 12 times the secon
g100num [7]

Answer:

18

Step-by-step explanation:

Let x represent smallest number and y represent second number.

We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be x+2.4.

We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:

15x=12y...(1)

15x=10(x+2.4)...(2)

Upon solving 2nd equation, we will get:

15x=10x+24

15x-10x=10x-10x+24

5x=24

x=\frac{24}{5}

x=4.8

Therefore, the smallest number is 4.8.

The biggest number would be x+2.4\Rightarrow 4.8+2.4=7.2.

Upon substituting x=4.8 in equation (1), we will get:

15(4.8)=12y

72=12y

y=\frac{72}{12}

y=6

Therefore, 2nd number would be 6.

Let us find sum of all numbers as:

4.8+6+7.2=18

Therefore, the sum of all 3 numbers would be 18.

Find the value of L in the equation. <br> s=(n÷2)(a+L)
Anon25 [30]

Answer:

2s/n-a=L

Step-by-step explanation:

So first we divide (n÷2) so it will be s/(n÷2) =a+L. Next we subtract L and get s/(n÷2)-a. That's not it yet, since 2 is being divided in the denominator, we have to reciprocal it meaning multiply, it to the top value. So it would 2s/n-a=L. But you can just leave it like that if you desire and your teacher doesn't mind.
