Mia jogs 3 kilometers in 20 minutes. There are about 0.6 miles in a kilometer. What is Mia’s approximate speed in miles per minute?

Answers

Answer 1

Answer: Speed is the ditance traveled by a certain object given a certain time span. To solve this problem we need to divide the distance by the time given. Before that, the problem asked us to get the speed in terms of miles per minute and we are given a distance of 3 kilometer. We have to convert this to miles. 3km(0.6miles/km) = 1.8 miles. The speed is then 1.8/20 = 0.09mi/min.

The maximum number of turning points of the polynomial is the degree of the polynomial minus 1. In this case the degree is 5, so the maximum number of turning points is 5-1=4.

Answer: $(x)/(2)$ + $(31y)/(2)$

Step-by-step explanation:

1) Combine multiplied terms into a single fraction.

$(1)/(2)$ x + $(31)/(2)$ ⋅ y

2) Multiply the equation by 1.

1x/2+ 31/2 ⋅ y

x/2 + 31/2 ⋅ y

3) Combine multiplied terms into a single fraction.

x/2 + 31/2 y

x/2 + 31y/2

4) Solution

x/2 + 31y/2

If....1=5 , 2=10, 3=30, then 4=?

Answers

The fourth term of the sequence will be 110

The given expression forms a sequence 5, 10, 30 ...

First term = 5

Second term = 10

Third term = 30

Let the fourth term be x

Taking their common difference

10 - 5 = 5

30 - 10 = 20

Since the multiplicity of the common difference is 4

Then T4 = 20(4) + 330

T4 = 80 + 30

T4 = 110

Hence the fourth term of the sequence will be 110

Your answer will be 4=120 because if you see how the pattern is going you'll notice that they are multiplying the last number to the first number. For example:
1=5, 2=10, 3=30

5 10
x 2 x 3
___ ___
10 30
So that means that:
30
x 4
___
120
