There are 10 sports balls in the equipment closet. Three are kickballs . Write the portion of the balls that are kickballs as a fraction, as a decimal, and in word form

Answers

Answer:

Proportion of kickball =

$p =(x)/(n) = (3)/(10)\n\np=0.3$

Step-by-step explanation:

We are given the following in the question:

Total number of ball, n = 10

Number of kickball,x = 3

Proportion of balls in fraction =

$p =(x)/(n) = (3)/(10)$

Proportion of balls in decimals =

$p =(x)/(n) = (3)/(10)\n\np=0.3$

Proportion in words =

3 out of 10 balls are kick balls that is 30% of the balls are kick balls.

The width of a rectangle is two-thirds of its length, and its area is 216 square meters. What is the length? is it 27 or 12

Answers

Answer:

The length of rectangle =18 m.

Step-by-step explanation:

Suppose of length of rectangle=x

Width of rectangle = $(2)/(3)x$

Area of rectangle = $216 m^2$

We have to find the length of rectangle .

Area of rectangle = $length* breadth$

Substitute the values in the given formula

$216=x* (2)/(3)x$

$216=(2)/(3)x^2$

$2x^2=216* 3$ By multiplication property of equality

$x^2=(216* 3)/(2)$ ( by division property of equality )

$x=√(324)=18$

Substitute the value then we get

Width of rectangle = $(2)/(3)* 18=12 m$

Hence, the length of rectangle =18 m.

Given f(x)=10-2x find f(7)

Answers

Answer: -4

Step-by-step explanation: The equation is a simple function having two variables x and y. f(x) can also be written as y.

Therefore, another way to write a function is y = 10-2x.

The question requires you to insert the value of one variable and calculate the other. In this case you have to find the value of function when x=7.

Insert 7 in place of x. So, the equation will look as follows.

f(x) = 10 - 2*7

f(x) = 10 - 14

f(x) = -4

Therefore, when x=7 the value of our function f(x) is equal to -4.

f(7)=10-14=-4
Answer=-4
