Answer:

  20 m

Step-by-step explanation:

The distance from the top car to the bottom car is equal to the diameter of the wheel. The diameter is 40 m, and that is twice the radius. The radius of the Ferris wheel is (40 m)/2 = 20 m.

What is x-2y=-1 and 2x+y=4 using elimination step by step
otez555 [7]

Answer:

x = 7/5  , y = 6/5

Step-by-step explanation using elimination:

Solve the following system:

{x - 2 y = -1 | (equation 1)

2 x + y = 4 | (equation 2)

Swap equation 1 with equation 2:

{2 x + y = 4 | (equation 1)

x - 2 y = -1 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + y = 4 | (equation 1)

0 x - (5 y)/2 = -3 | (equation 2)

Multiply equation 2 by -2:

{2 x + y = 4 | (equation 1)

0 x+5 y = 6 | (equation 2)

Divide equation 2 by 5:

{2 x + y = 4 | (equation 1)

0 x+y = 6/5 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 14/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 7/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Collect results:

Answer: {x = 7/5  , y = 6/5

Find the range of the following data set. 1 1/4, 5/8, 3/4, 1/2, 1 1/2, 1 3/4
hodyreva [135]

Answer:

Option C is correct

Step-by-step explanation:

First we will convert the mixed fractions into fraction form.

5/4, 5/8, 3/4, 1/2, 3/2, 7/4

Now, to find the range the formula used is:

Range= Maximum Value - Minimum Value

To find the maximum value and minimum value in fractions, we need to make the denominator of each fraction same. Since the highest value of denominator is 8, so other fractions denominator should be 8.

10/8, 5/8, 6/8,4/8,12/8,14/8

Maximum Value = 14/8 (having highest numerator)

Minimum value = 4/8 (having lowest numerator)

Range of data set = Maximum Value - Minimum value

                             = 14/8 - 4/8

                             = 10/8 = 5/4

                             = 1 1/4

so, option C is correct.

The sum of the squares of two consecutive positive even numbers is 340. Find the numbers
puteri [66]

Answer:

The two consecutive even numbers are 12 and 14.

Step-by-step explanation:

Set up the equation, which turns out to be a quadratic, solve for n:

(2n)^2+(2(n+1))^2=340\\4n^2+4n^2+8n+4=340\\8n^2+8n-336=0\\n^2+n-42=0\\\implies (n_1=-7),\,\,\,n_2=6

We are looking for positive even numbers, so the solution -7 is not valid. The solution for n is 6, and the two consecutive even numbers are:

2*6=12

2*7=14

Test: 12*12 + 14*14 = 340
