What is the sum of the measures of the interior angles of a 10-sided figure?
o 1,440°
o 180°
o 360°
o 1,800°

Answer:

See solutions below

Step-by-step explanation:

2) angle at the vertex is half that of its intercepted arc;

51 = 1/2(14x-38)

51*2 = 14x-38

102 = 14x-38

14x = 102 + 38

14x = 140

x = 140/10

x = 14

3) 9x+7 = 1/2(68)

9x + 7 = 34

9x = 34-7

9x = 27

x = 27/9

x = 3

4) 114 = 1/2(30-(8x-36+40))

114 = 1/2(360-8x+36-40)

114*2 = 356 - 8x

-8x = 228-356

-8x = -128

x = 128/8

x = 16

Answer:2

Step-by-step explanation:

51+14x-38=180

13+14x=180

14=167

X=12

Answer:

x=8

y=14

Step-by-step explanation:

3x+18=5x+2

2x=16

x=8

..........

5y+68=3y+96

2y=28

y=14

Answer:

x=8, y=14

Step-by-step explanation:

Opposite angles are equal to eachother. Therfore this setup is a simple equation

3x+18=5x+2

Simplify and x=8

5y+68=3y+96

Simplify and y=14

Have a nice day ;)

Answer:

D)

Step-by-step explanation:

for each equation, substitute zero for 'x' and solve for 'y' (this will be the y-int)

A)  y-int = 2

B)  y-int = 0

C)  y-int = 1

D)  y-int = 1.5

Answer:

The other guy was right, it's 30.

Step-by-step explanation:

Think of this as 150% of 20, or 1.5 x 20.

This makes it easier to get the answer of 30.

Just a life hack I saw that made math easier :)

Answer:

The Great Chicago Fire was a conflagration that burned in the American city of Chicago during October 8–10, 1871. The fire killed approximately 300 people, destroyed roughly 3.3 square miles (9 km 2) of the city, and left more than 100,000 residents homeless. The fire began in a neighborhood southwest of the city center.

Step-by-step explanation:

Origin

The fire is claimed to have started at about 8:30 p.m. on October 8, in or around a small barn belonging to the O'Leary family that bordered the alley behind 137 DeKoven Street.

Spread

When firefighters finally arrived at DeKoven Street, the fire had grown and spread to neighboring buildings and was progressing toward the central business district.

Aftermath

Once the fire had ended, the smoldering remains were still too hot for a survey of the damage to be completed for many days. Eventually, the city determined that the fire destroyed an area about 4 miles (6 km) long and averaging ⁄4 miles (1 km) wide, encompassing an area of more than 2,000 acres (809 ha).

Answer:

40 squared cm

Step-by-step explanation:

The formula for this shape would be

A=bh

This is the same as a rectangle because it is technically a rectangle, don't get confused by the triangle.

Imagine that you can cut this shape, so cut where the dotted line is, put it on the opposite side, and you get a rectangle.

So:

10 × 4 = 40

Answer:

301.440 mi²

Step-by-step explanation:

Surface area of a cylinder = 2πrh + 2πr²

Where,

Radius, r = 6 mi

Height, h = 2 mi

Surface area of a cylinder = 2πrh + 2πr²

= (2 * 3.14 * 6 * 2) + (2 * 3.14 * 6²)

= 75.36 + (6.28 * 36)

= 75.36 + 226.08

= 301.44 mi²

To the nearest thousandth

Surface area of a cylinder = 301.440 mi²

Answer:

4 and 5 alternate interior  8=60

Step-by-step explanation:

Alternate means... well... alternating so they are not on the same side but on different sides. Interior means inside si the angles that match this would be 4&5 or 3&6, but 4&5 is one of the options.

1 and 8 are the same value. 1,4,5,8 are all 60 degrees.

Answer:

Picture please

Step-by-step explanation:

I cannot identify the 3-D shapes unless if there is a picture.

The total volume of the solid is 2,160 unit³.

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.

The unit of volume is in cubic units such as m3, cm3, in3 etc.

First, Base area

= 1/2 x b x h

= 1/2 x 15 x 12

= 15 x 6

= 90 unit²

Now, Volume of Figure

= Base area x h

= 90 x 24

= 2,160 unit³
