Answer : The location on the number line to plot the point is shown below.

Step-by-step explanation :

Number line : It is defined as a straight line with the numbers that are placed at equal intervals along its length.

As we move from zero to the right the numbers are positive.

As we move from zero to the left the numbers are negative.

The given expression is:

1.4 + (-0.8)

By solving the expression, we get:

⇒ 1.4 - 0.8

⇒ 0.6

Which is a good comparison of the estimated sum and the actual sum of 7 9/12 + 2 11/12?
natta225 [31]
7 9/12 = 7.75
2 11/12 = 2.917

So we can round both of these up.

7.75 rounds to 8
2.917 rounds to 3

8 + 3 = 11

So the estimated sum is 11.

7 9/12 + 2 11/12 = 10 2/3

So the actual sum is 10 2/3.

The estimated sum is a pretty good estimate to the original number.

\bigodot \: A.\: 3x^2-17

Step-by-step explanation:

  • f(x) =3x + 1 (Given)

  • g(x)=x^2-6 (Given)

  • \implies (f.g)(x)=3(x^2-6)+1

  • \implies (f.g)(x)=3x^2-18+1

Some one help me with this pls!!!
Daniel [21]

Answer:

V = 2,495.5 ft³

Step-by-step explanation:

Volume of the given cylinder = πr²h

Where,

π = 3.14

radius (r) = ½(17) = 8.5 ft

height (h) = 11 ft

Plug in the values into the formula

V = 3.14 × 8.5² × 11

V = 3.14 × 72.25 × 11

V = 2,495.515

V = 2,495.5 ft³ (to nearest tenth)
