Answer:

  B.  No, Danielle needs to remove 1 rectangle from the ramp and 1 rectangle from the block.

Step-by-step explanation:

It is true that the ramp has 2 triangular and 3 rectangular surfaces, and the block has 6 rectangular surfaces. However, Danielle doesn't want to paint the bottom rectangular surface of either the ramp or the block, so needs to remove one rectangle from each for her area computation.

irakobra [83]

Answer:

A. y=-8.583x+475.215

Step-by-step explanation:

We are given,

The table representing the closing prices of stock for the last five days is,

Day                         Value

1                                472.08

2                               454.26

3                                444.95

4                                439.49

5                                436.55

Using the linear regression calculator, we have that,

<h3>The linear equation that best fits the data is y=-8.583x+475.215</h3>

Thus, option A is correct.

Solve the compound inequality,
Feliz [49]

Answer:

\large\boxed{y\in(-6,\ \infty)}

Step-by-step explanation:

(1)\\2y-2>-14\qquad\text{add 2 to both sides}\\\\2y-2+2>-14+2\\\\2y>-12\qquad\text{divide both sides by 2}\\\\\dfrac{2y}{2}>\dfrac{-12}{2}\\\\y>-6

(2)\\\\4y-4\geq12\qquad\text{add 4 to both sides}\\\\4y-4+4\geq12+4\\\\4y\geq16\qquad\text{divide both sides by 4}\\\\\dfrac{4y}{4}\geq\dfrac{16}{4}\\\\y\geq4

\text{From (1) and (2) we have:}\\\\y>-6\ or\ y\geq4\to y\in(-6,\ \infty)\ \cup\ [4,\ \infty)\Rightarrow y\in(-6,\ \infty)

HELP PLEASE I NEED HELp
lidiya [134]

Answer:

Step-by-step explanation:

GH bisects ∠FGI

∠HGI = ∠HGF

4x - 14 = 3x - 3

4x = 3x - 3 + 14    {Add 14 to both sides}

4x = 3x + 11             {Subtract 3x from both sides}

4x - 3x = 11

x = 11

∠HGI = 4x - 14

         = 4*11 - 14

         = 44 - 14

         = 30°

∠FGI = 30 + 30

        = 60°
