a map has a scale of 1m represents 2 km. write this scale as a ratio in its simplest form

Answer:

153.86 units squared.

Step-by-step explanation:

given

diameter (d) = 14

radius (r) = 14/ 2 = 7

Area of the circle

= πr²

= 3.14 * 7²

= 3.14 * 49

= 153.86 units squared

Hope it will help :)❤

Answer:

3.80

Step-by-step explanation:

Answer:

3.801

Step-by-step explanation:

Divide and move your decimals.

Answer:

Step-by-step explanation:

if (x,y) is the centroid. Then x=(x1+x2+x3)/3,y=(y1+y2+y3)/3

5.

x=(-2+4+10)/3=4

y=(6+0+6)/3=4

centroid=(4,4)

6.

x=(3+5-2)/3=2

y=(3-1+1)/3=1

centroid=(2,1)

Answer:

Adding them together. x = 3/2, y = 8

Step-by-step explanation:

Adding because we want to get rid of a variable. If we add, 2x + 6x = 8x, 1/2 * y + (-1/2 * y) = 0, and 7 + 5 = 12. Adding gets rid of the y variable.

By adding we get that 8x = 12 which gives us x = 12/8 = 3/2

Substituting this back into either equation will give us y = 8.

Answer:

The answer is 1m/s

Answer: 69.2%

Step-by-step explanation:

There are 101 Year 13 students out of a total number of 146 pupils.

To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:

= Year 13 students/ Total students * 100%

= 101 / 146 * 100%

= 0.692 * 100%

= 69.2%

Answer:

LOLLLLLLLLLLLLLLLLLLLLLL

Answer:

(x - √7*√x) / (x - 7)

Step-by-step explanation:

I suppose your expression is √x / (√x + √7)

(√x * (√x - √7)) / ((√x + √7) * √x - √7)) = (√x * √x - √7 * √x) / (x - 7)

= (x - √7*√x) / (x - 7)

Answer:

Step-by-step explanation:

I just took the test on edge

Answer:

y = tan-1 (31/23)

Formula: SOHCAHTOA

TOA: tan = opposite/adjacent

31 / 23 = 1.3478

tan-1 of 1.3478 is 53.4264

53.4264 = 53 (rounding to the nearest degree)

y = 53 degrees

Answer:

Step-by-step explanation:

4/28 = 1/7 = 1:7

Answer:

Vincent’s plane is cruising at an altitude of 3.2 × 10^4 feet.

Convert the number to standard notation.

3.2 × 10^4 feet  

=

3.2 • 10,000 feet

=

32,000 feet

Step-by-step explanation:

This is the sample answer from Edmentum.

Answer:

Question 1 part a =

Vincent’s plane is cruising at an altitude of 3.2 × 104 feet.

Convert the number to standard notation.

3.2 × 104 feet  

= 3.2 • 10,000 feet

= 32,000 feet

Part b =

Felix’s skydiving altitude is 1.28 × 105 feet.

Convert the number to standard notation.

1.28 × 105 feet  

= 1.28 • 100,000

= 128,000 feet

Part c =

Subtract the two altitudes to find the difference.

128,000 feet − 32,000 feet = 96,000 feet

The difference of their altitudes is 96,000 feet.

Part d =

The difference of the altitudes is 96,000 feet.

Covert 96,000 to scientific notation:

96,000 feet = 9.6 × 104 feet

Question 2 part a  =

Vincent’s plane’s altitude is 3.2 x 10^4 feet.

Felix’s skydiving altitude is 1.28 x 10^5 feet.

Transform 3.2 x 10^4  so its exponent matches the power of 10 in 1.28 x 10^5.

To do so, multiply and divide the number by 10.

3.2 x 10^4 = 10/10 x 3.2 x 10^4

                 = 3.2/10 x 10^4 x 10

                 = 0.32 x 10^5

Part b =

Calculate the difference of the two altitudes:

1.28 × 105 – 0.32 × 105

=  (1.28 – 0.32) • 105

= 0.96 • 105

The difference of their altitudes is 0.96 •105 feet.

Part c =

The difference of Vincent’s and Felix’s altitudes is 0.96 x 10^5 feet.

To convert the answer to scientific notation, multiply and divide the number by 10.

0.96 x 10^5 = 10/10 x 0.96 x 10^5

                   = (0.96 x 10) x (10^5 x 10^-1)

                   = 9.6 x 10^4 feet

In scientific notation, the difference of Vincent’s and Felix’s altitudes is 9.6 x 10^4 feet.

Question 3 =

The altitudes are the same. That means you can subtract numbers given in scientific notation using either of two methods: convert them to standard notation and then perform the subtraction, or subtract the numbers in scientific notation without converting them to standard notation.

Your answer is in bold. All edmentum answers :)

Answer:

Step-by-step explanation:

           0           -3               y intercept is -3 when x is 0

            x           y

    -1     1              0   -3      subtract 1 for x   and  3 for y

          2             3

          3             6

          4             9

x only increase by ones        y increases by threes

so the slope is   y/x   which means     3/1    up three, 1 to the right

y=mx+b

y = 3x-3

Answer:

x = 8

Step-by-step explanation:

-8 is the value of the y-coordinate, so you must find the x-coordinate that will match with that value. As you move horizontally to the right at y = -8, you will see that x = 8 is met.

Answer:

8^2-60 ,   11^1   , 2^2x5

Step-by-step explanation:

2^2= 4

4 x 5 = 20

11^1= 11

8^2= 64

64-60 = 4

Answer:

y - intercept = -5/2

x-intercept = -2

Step-by-step explanation:

-5x - 4y = 10

At y-intercept , x = 0

0 - 4y = 10

       y = 10/-4

       y = -5/2

At x-intercept, y = 0

   -5x  - 0 = 10

           -5x = 10

              x = 10/-5

               x = -2

Answer:

D) 10.00 for a 36 pack

Step-by-step explanation:

(I'm going up by the smallest pack to the highest because I noticed they are all multiples of 6)

1.80 for a 6 pack (double it to become a 12 pack)

3.60 for a 12 pack but the other 12 pack is more expensive making a 6 pack cheaper. (add another 6 pack)

5.40 for a 18 pack (add another 6pack)

7.20 for a 24 pack so this means the 6pack is more expensive and a 24pack is cheaper (in gonna keep adding till we get to 36 pack)

9 for a 30 pack

10.80 for a 36 pack

Answer:

Step-by-step explanation:

1) Area of garden = side * side

                             = 10* 10

                             = 100 Sq.m

2) Area of each flowerbed = 1*1 = 1 sqm

3)  Area of 4 flowerbed = 1 * 4 = 4 sqm

 Area of the remaining garden = Area of garden - area of 4 flower bed

                                                    = 100 - 4

                                                    = 96 sq.m

4) Length of the fence = 4 *side

                                      = 4 * 10 = 40 m

5)  Cost of planting in the remaining garden = 96 * 20

                                                                          = ₹ 1920

Here is the answer I solved.
