What is 1/5 of 45? please help my 10 yr. Old.

Sedaia [141]

Answer:
9

Explanation:
To get the fraction of a number, you will simply multiply the fraction by the given number.

For the given, we want to find $\frac{1}{5}$ of 45.
This can be computed as follows:
 $\frac{1}{5}$ of 45 = $\frac{1}{5}$ * 45

= $\frac{1*45}{5}$

= $\frac{45}{5}$

= 9

Therefore, $\frac{1}{5}$ of 45 is 9

Hope this helps :)

Y=-x^2-10x+24 What is the y value of the vertex?

emmasim [6.3K]

Answer:

Step-by-step explanation:

1.) Get the equation in the form y = ax^2 + bx + c.

2.) Calculate -b / 2a. This is the x-coordinate of the vertex.

3.) To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

1.) y = -x^2 - 10x + 24

2.) -(-10) / 2(-1) = -5

3.) y = -(-5)^2 - 10(-5) + 24

y = -25 + 50 + 24

y = 49

The sum of four consecutive whole numbers is 230.Find the numbers.

taurus [48]

х is the first number
(x + 1) is the second number
(x + 2) is the third number
(x + 3) is the fourth number

x + x+1 + x+2 + x+3 = 230
4x + 6 = 230
4x = 230 - 6
4x = 224
x = 224/4
x = 56 the first number
56 + 1 = 57 the second number
56 + 2 = 58 the third number
56 + 3 = 59 the fourth number

Answer: 56, 57, 58, 59.
