Please help find the amount of interior angles in the shape.
gladu [14]

The polygon has 11 sides.

The measure each interior angle is 147.272°.

Solution:

The given shape is a regular polygon.

(a) Number of sides of the polygon = 11

The polygon has 11 sides.

(b) To find the measure of each interior angle:

Each interior angle of a regular polygon

                                    $=\frac{(n-2) \times 180^{\circ}}{n}

                                    $=\frac{(11-2) \times 180^{\circ}}{11}

                                     $=\frac{9 \times 180^{\circ}}{11}

                                     =147.272^\circ

The measure each interior angle is 147.272°.

I need help wiith all❤️It’s urgent please
faltersainse [42]

Answer:

1. D

2. D

3. B

Step-by-step explanation:

1. The y-axis of the graph is the volume of gas in the tank and the x-axis is the distance traveled. So the y-intercept represents how much gas is in the tank before it has been driven anywhere. D

2. Just by inspecting the graph, we can see that the x-intercept is 240. So answers a and c are denitely incorrect. Also, since we know the graph is comparing the distance from the house to time, we can observe that the x-intercept is when the cyclist is at home or 0 miles from their house. So the x-intercept must represent the duration of time it took the cyclist to reach home. D

3. Ok so we know the equation of the line is 3x-8y-12=0, and we're trying to find the x and y intercepts. So we can plug 0 in for x to find the y-intercept. And plug 0 in for y to find the x-intercept.

x-intercept: y=0

3x-8(0)-12=0

3x-12=0

3x=12

x=4

=> (4,0)

y-intercept: x=0

3(0)-8y-12=0

-8y-12=0

-8y=12

y=-3/2

=> (0,-1.5)

So the answer is B

4. We can see that one prize is worth $6, so in theory, if the relation was linear we should be able to say that the cost of the number of prizes you buy is 6 times the number of prizes bought. Since we can see that that is not true, we can determine that the data is non-linear. We can also tell that the data is discrete because you can't buy a partial prize. So the answer is C

I'm sorry I don't have time to finish the rest of the questions!! I hope my other answers are helpful though!

Solve the inequality (2x-4) + 110 ≤ 120
miskamm [114]

Answer:

x ≤  7

Step-by-step explanation:

(2x-4) + 110 ≤ 120

Combine like terms

2x +106 ≤ 120

Subtract 106 from each side

2x+106 -106 ≤ 120-106

2x ≤  14

Divide each side by 2

2x/2 ≤  14/2

x ≤  7

3/8(2x-8/3x)=21 solve the equation for x​
mart [117]

Answer:

\boxed{\bold{x=-84}}

Explanation:

Multiply Both Sides By 8:

= \bold{8\cdot \frac{3}{8}\left(2x-\frac{8}{3}x\right)=21\cdot \:8}

Simplify:

= \bold{-2x=168}

Divide Both Sides By -2:

= \bold{\frac{-2x}{-2}=\frac{168}{-2}}

Simplify:

= \bold{x=-84}

//Mordancy //.
