Answer:

Step-by-step explanation:

Volume of the model of moon = 4/3(πr³)

= 4/3(π)(1)³

= 4.2 feet³

Volume of cylinder = πr²h

= (3.14)(0.5)²(0.5)

= 0.39 feet³

Cylindrical clay boxes to be used = 4.2/0.39

=10.7 ≈ 11

Two numbers total 42 and have a difference of 8 find the two numbers

FinnZ [79.3K]

X+y = 42
x-y = 8
x = 8+y

Substitute it in 1st equation,
8+y+y=42
2y = 34
y = 17

Substitute it in 1st eq.,
x = 42-17 = 25

So, the two numbers are 25 & 17

Hope this helps!

This table models a linear function. x −8 −4 4 8 y −3 0 6 9 Enter the coordinates of the y-intercept in the boxes.

Answer:

y-intercept is 3

Step-by-step explanation:

We are given table

x: -8 -4 4 8

y: -3 0 6 9

We can select any two points

$x_1=-8,y_1=-3$

$x_2=-4,y_2=0$

Firstly, we will find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{0+3}{-4+8}$

$m=\frac{3}{4}\quad$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

we can plug values

$y+3=\frac{3}{4}(x+8)$

now, we can solve for y

$y=\frac{3}{4}x+3$

For finding y-intercept , we can plug x=0

$y=\frac{3}{4}\times 0+3$

$y=0+3$

$y=3$

So,

y-intercept is 3

Answer:

The number of kids NOT wearing socks in the gym = 20

Step-by-step explanation:

Here, the total number of kids in the gym = 80

Now, 75% of the kids are wearing socks.

Let us assume the number of kids wearing socks = m

⇒ 75 % of 80 = m

Calculating the value of m ,we get:

$\frac{75}{100} \times 80 = m\\\implies m = 60$

⇒ 60 kids are wearing socks.

Kids not wearing socks = Total kids in gym - Kids wearing socks

= 80 - 60 = 20

Hence, the number of kids NOT wearing socks in the gym = 60.
