7 0

Answer:

True.

Step-by-step explanation:

Remember that the horizontal line test checks if a function is one-to-one. If a horizontal line passes through a graph more than once, the function has more than one x-value for at least one y-value.

Machines a and t were both cleaned this week machine a is cleaned every 15 weeks and machine t is cleaned every 12 weeks what is
lapo4ka [179]

Answer:

60 weeks

Step-by-step explanation:

Factor both numbers 12 and 15:

  • 12=2\cdot 2\cdot 3;
  • 15=3\cdot 5.

Find LCM(12,15). The common factor is only 3, multiply ths common factor by all factors that remain. Then

LCM(12,15)=3\cdot 2\cdot 2\cdot 5=60.

This means that the fewest number of weeks that will pass before both machines are cleaned again in the same week is 60 weeks.

The total surface area of this cuboid is 112^2
Nastasia [14]

The value of x is 3

<h3>How to solve for x?</h3>

The given parameters are:

Length = 10cm

width = 2cm

Height = x

The surface area is calculated as;

Area = 2 *(lw + lh + wh)

So, we have:

2 * (10 * 2 + 2x + 10x) = 112

Evaluate the like terms and divide by 2

20 + 12x = 56

Subtract 20 from both sides

12x = 36

Divide by 12

x = 3

hence, the value of x is 3
