Answer:

Look in step by step

Step-by-step explanation:

The way to read coordinates is to know these steps.

(#,#)

the first number is the x number which on the graph is the horizontal line and the second number is the y number which on the graph is vertical.

Theres also negatives which is the same thing but its on the lower side of the graph.

So now for example you take -4,-9.

To make it easy move the dot to the center or the (0,0) cords. Then follow the numbers. When you start on the zero cord you will look at the numbers, it says -4 so drag the dot 4 units to the left where the line says -4. Then drag it down 9 units so its on the cords. Hope this helps!!

Answer:

Ok so for (0,8 1/2), drag the dot from the middle, up to 8 but then move up a little bit more so it is between the 8 and 9. Next, for (-4, -9) drag one of the other dots to the -4 on the horizontal line, but then move it down to the -9 on the vertical line. And finally for (-6,5), you should put the last dot on the -6 on the horizontal line, but move it up five spaces until it is at the 5 on the vertical line.

I hope I was able to help you, if you still do not understand I will try to explain a little bit more.

Please help with this equation:<br><br> 4.5(8-x)+36=102-2.5(3x+24)
Solnce55 [7]

answer

x=14

Step-by-step explanation:

4.5(8-x)+36=102-2.5(3x+24)

36-4.5x+36=102-7.5x-60

-4.5x=42-7.5x

7.5x-4.5x=42

3x=42

x=42/3

x=14

Simplify<br> a(cube)-1000b(cube)<br> 64a(cube)-125b(cube)
Elanso [62]

The simplification of a³ - 1000b³ and 64a³ - 125b³ is (a - 10b) × (a² + 10ab + 100b²) and 4a - 5b) • (16a² + 20ab + 25b²) respectively.

<h3>Simplification</h3>

Question 1: a³ - 1000b³

a³ - b³

= (a-b) × (a² +ab +b²)

  • 1000 is the cube of 10
  • a³ is the cube of a¹
  • b³ is the cube of b¹

So,

(a - 10b) × (a² + 10ab + 100b²)

Question 2: 64a³ - 125b³

a³ - b³

= (a-b) × (a² +ab +b²)

  • 64 is the cube of 4
  • 125 is the cube of 5
  • a³ is the cube of a¹
  • b³ is the cube of b¹

So,

(4a - 5b) • (16a² + 20ab + 25b²)

In ΔJKL, k = 9.6 cm, l = 2.7 cm and ∠J=43°. Find ∠L, to the nearest 10th of a degree.
Bogdan [553]

Answer:

L = 10.64°

Step-by-step explanation:

From the given information:

In triangle JKL;

line k = 9.6 cm

line l = 2.7 cm; &

angle J = 43°

we are to find angle L = ???

We can use the sine rule to determine angle L:

i.e

\dfrac{j}{SIn \ J} = \dfrac{l}{ SIn \ L}

Using Pythagoras rule to find j

i,e

j² = k² + l²

j² = 9.6²+ 2.7²

j² = 92.16 + 7.29

j² = 99.45

j = \sqrt{99.45}

j = 9.97

∴

\dfrac{9.97}{Sin \ 43} = \dfrac{2.7}{ Sin \ L}

{9.97 \times    Sin (L ) = (2.7 \times Sin \ 43)

=  Sin \ L = \dfrac{ (2.7 \times Sin \ 43)}{9.97 } \\ \\ =  Sin \ L = \dfrac{ (2.7 \times 0.6819)}{9.97 }  \\ \\  = Sin \ L = 0.18466 \\ \\  L = Sin^{-1} (0.18466) \\ \\  L = 10.64 ^0

If the volume of the bat is 82
Assoli18 [71]

The volume that is left to be filled is approximately: 3,332.6 in.³

<h3>What is the Volume of a Box?</h3>

Volume of a box = (length)(width)(height)

Given the following:

Volume of the bat = 82 cubic in.

Length of box = 30 in.

Width = 18.97 in.

Height = 6 in.

The remaining volume to be filled = volume of box - volume of bat

= (30)(18.97)(6) - 82

= 3,332.6 in.³
