Answer:

FGE = 180 - (14 + 78)°

= 88°

so angle GEC = 88°

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 92/4

= 23

Using long division to find the quotient, what changes do you first

lora16 [44]

Answer:

$\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4$

Step-by-step explanation:

Given

$Dividend = 125x^3 - 8$

$Divisor = 5x - 2$

Required

Determine the quotient

See attachment for complete process.

First, divide 125x^3 by 5x

$\frac{125x^3}{5x} =25x^2$

Write $25x^2$ at the top

Multiply $5x - 2$ by $25x^2$

$= 125x^3 - 50x^2$

Subtract from 125x^3 - 8

i.e.

$125x^3 - 8 - (125x^3 - 50x^2) = 50x^2 - 8$

Step 2:

Divide 50x^2 by 5x

$\frac{50x^2}{5x} = 10x$

Write $10x$ at the top

Multiply $5x - 2$ by $10x$

$= 50x^2 - 20x$

Subtract from 50x^2 - 8

i.e.

$50x^2 - 8 - (50x^2 - 20x) = 20x - 8$

Step 3:

Divide 20x by 5x

$\frac{20x}{5x} = 4$

Write $4$ at the top

Multiply $5x - 2$ by $4$

$= 20x - 8$

Subtract from 20x - 8

i.e.

$20x - 8 - (20x - 8) = 0$

Hence:

$\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4$

A survey of voters explored the relationship between the ages of voters and wether or not they support building skateboard ramps

Novosadov [1.4K]

Answer:

(a)12%

(b)20%

Step-by-step explanation:

(a)In the age group 58 and above:

Number in favor of building the skateboard ramps=6

Number opposed to building the skateboard ramps=44
Total = 50

Percentage of those in favor = $\frac{6}{50}X100 =12\%$

(b)In the age group 18-37

Number in favor of building the skateboard ramps=40

Number opposed to building the skateboard ramps=10
Total = 50

Percentage of those opposed to it = $\frac{10}{50}X100 =20\%$

(c)

Total Number of those in favor of building the skateboard ramps=73

Total Number opposed to building the skateboard ramps=77
Total = 150

Percentage of those in favour = $\frac{73}{150}X100 =48.67 \approx 49\%$

Please draw and label a figure for this sentence in geometry

Kaylis [27]

Answer:

First, plot points A & B on a graph.

Collinear just means 3 or more points in a straight line (because just 2 points are always collinear, since a straight line can always be drawn through two points.

The instructions don't state a specific area in which points C & D have to be in, so you can put them anywhere, as long as they are collinear with each other, but not any other points,

i.e. putting three units up and two units left of points A & B

So let's make up some points for C & D that are on a straight line.

Remember, this line does not have to be horizontal! As long as it's a straight line, any direction will do.

Here are some points that you can choose from:

C(-1, 1); D(-1, -1)
C(4, 5); D(4, -5)
C(3, 4); D(3, 5)
Anything that doesn't fall on x=2 or y=±3.

For "F" just pick a set of coordinates off to the side and label it

F(-3,-6)
F(-4, 8)
F(6, -7)

You can even use half values if you want:

(0.5, 3.2)
(1.2, -4.1)
(-9.1, -0.2)

As long as your plotted points meet the criteria:

C & D are Collinear
A, B, C, D, & F must not land on the same straight line.

8(c-9)=6(2c-12)-4c How to solve questions like this

Gennadij [26K]

Step 1-Distributive Property
8c-72=12c-2-4c
Step 2-Combine Like Terms
8c-72=8c-2
Step 3-Divide both 8c's by 8
-72=-2 -72 does NOT equal -2 so this equation has no solution...Hope this helps have a great Day!!!
