$5x - 3 < - 23 \\ 5x < - 20 \\ x < - 4$
$2x + 7 > 1 \\ 2x > - 6 \\ x > - 3$

x < - 4 or x > - 3
The answer is the 2nd option.

Hope this helps. - M

Answer:

2294 balls is the approximate number of balls

Step-by-step explanation:

Find the volume occupied a ball of radius 3inches

Volume of a sphere=4/3 $\pi$ ×r³

where r is the radius in inches

4/3× $\pi$ ×3³ = 36 $\pi$

=113.11 in³

Find volume of a rectangle prism

v=l×w×h where l is length of prism, w is width of prism and h is height of prism

L=10ft=10×12=120 inches

w=5ft=5×12=60 inches

h=3ft= 3×12= 36 inches

v=120×60×36=259200 in³

Number of balls needed

N=volume occupied by a single ball/volume of the rectangular prism

N=259200/113.11 =2291.57⇒2292 balls

you were 20 inches tall at birth, and 48 inches tall on your 8th birthday. Create a linear equation to represent this equation.

Marianna [84]

Answer:

Part a) $y=3.5x+20$

Part b) $90\ in$

Step-by-step explanation:

Part a) Create a linear equation to represent this situation

Let

x -----> the number of years

y ----> the height in inches

we have the points

(020) ----> at birth the height was 20 inches

(8,48) ---> 8th birthday the height was 48 inches

step 1

Find the linear equation in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

Find the slope m

$m=(48-20)/(8-0)\\m=3.5\ in/year$

Find the value of b

$b=20\ in$ ----> the point (0,20) is the y-intercept

substitute

$y=3.5x+20$

Part b) According to your equation, how tall will you be at age 20?

For x=20 years

substitute the value of x in the linear equation and solve for y

$y=3.5(20)+20$

$y=90\ in$

All the factory workers in a steel mill either purchased their breakfast I. The company cafeteria or bought their breakfast from

Lana71 [14]

Answer:

There are 200 factory workers employed at steel mill.

Step-by-step explanation:

Let the total number of workers employed at steel mill be 'x'.

Now Given:

Percentile Number of workers purchased breakfast = 26%

So we can say that;

Number of workers purchased breakfast = $\frac{26}{100}x=0.26x$

Also Given:

Number of workers brought breakfast from home = 148

Solution:

Now we can say that;

total number of workers employed at steel mill is equal to sum of Number of workers purchased breakfast and Number of workers brought breakfast from home.

framing in equation form we get;

$x=0.26x+148$

Combining the like terms we get;

$x-0.26x=148\\\\0.74x=148$

Dividing both side by 0.74 we get;

$\frac{0.74x}{0.74}=\frac{148}{0.74}\\\\x= 200$

Hence There are 200 factory workers employed at steel mill.
