Solve the inequality and show on a number line<br><br> (picture included below)
aksik [14]

Step-by-step explanation:

I cant show a number line so i'll do my best to explain how its graphed.

15) x - 1 < 15

add 1 to both sides:

x < 16

Because it is less than, rather than less than or equal to, it's graphed with an open circle (not filled in) on 16, and everything less than 16 highlighted

---------------------------------------------------------

16) 2(y + 1) - 2 ≥ 12

distribute the 2:

2y + 2 - 2 ≥ 12

combine like terms

2y ≥ 12

isolate y:

y ≥ 6

This one is greater than or equal to, so it's graphed with a closed circle (filled in) and everything above 6 highlighted

What is the length of the diagonal for the given rectangular prism to the nearest whole unit? A) 10 cm B) 11 cm 6 cm D) 13 cm
raketka [301]

Hi there! :)

\large\boxed{\text{B. 11 cm.}}

Begin by using Pythagorean theorem to solve for the length of the diagonal of the base:

a² + b² = c²

Use the length and width in the equation:

8² + 3² = c²

64 + 9 = c²

73 = c²

c ≈ 8.54 cm

Now, we can find the length of the diagonal of the prism using our calculated diagonal of the base and the height. Use the same equation:

(8.54)² + 7² = c²

73 + 49 = c²

122 = c²

√122 = c

c = 11.05 ≈ 11 cm. The correct answer is B.

A water truck is filling a swimming pool. The equation that represents this relation is y=18.25x where y is the number of gallon
QveST [7]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, however, one of the requirements of this question while I searched, was to make a table and sketch the equation.

If this is the case, then, all you need to do is take the equation, Assume some values for x, and compute the values of y. Then, you can do the graph.

I begin with value from 0 to 10.

This is the example of calculations:

x = 0

y = 18.25*0 = 0

for x = 0, we get y = 0. For x = 2:

y = 18.25 * 2 = 36.5

If we keep doing this, we should get a straight line. See the graph and attached table. If the question is asking another thing, then please get back to me to answer it.
