Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

Answer:

  4600 miles

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

  A speed - B speed

  45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h

Explorer B travels 4600 fewer miles in an hour than Explorer A.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Step-by-step explanation:

If complete precision is not needed:

1.  Fill the 5 cup container with water.

2. Pour out just enough into the 3 cup container to fill it.

3. The water left in the 5-cup container will measure 2 cups.

4.  Estimate half of this two cups of water.

There is no association between the height and the hand span.

We can only establish an association when there is a consistent rate of increase or decrease between two variables. The increase or decrease is linear when they occur smoothly.

As we can see, we can not establish any particular relationship between the height and the hand span hence we conclude that there is no association between them.

Step-by-step explanation:

Quite easy, you can use substitution

First look at the simplest row that can be solved by itself

row 2:

2strawberries +4 = 10

2 strawberries= 6

1 strawberry = 3

Row 3: Strawberry(3)+ orange=8

1 orange= 5

Rpw 4: 14= 1coconut +orange(5)

1 coconut= 9

Row 1: Coconut(9)+ watermelon+ coconut(9)= 21

2 coconut(18)= 21

1 watermelon = 3

Answer:

Time = 1.27 x 10^1 minutes

Step-by-step explanation:

To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.

Given:

Speed of light = 1.12 x 10^7 miles per minute

Distance between the Sun and Mars = 1.42 x 10^8 miles

Time = Distance / Speed

Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)

Time = (1.42 / 1.12) x 10^(8 - 7) minutes

Time = 1.27 x 10^1 minutes

Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.

Answer:

Its c. c = 50.

Step-by-step explanation:

First, we need to figure out what the equation equals.

7 + 7/7 + 7*7 - 7 = x

PEMDAS

Parentheses, exponents, division/fraction, addition, subtraction.

7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.

7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.

Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.

c is the only one who has a calculation of 50.
