The sum of 9 and a number is twice a number plus 14. How would I write this as an equation?

Answer:

6.75 minutes / mile.

Step-by-step explanation:

Time: 13.5 minutes

distance: 2 miles

rate: ?

You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.

13.5 minutes

2 miles

13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile

Answer:

Answer: KL is 10

Step-by-step explanation:

JL = JK + KL

first get value of x:

[tex]26 = (8x + 8) + (3x + 7) \\ 26 = (8x + 3x) + (8 + 7) \\ 26 = 11x + 15 \\ 11x = 26 - 15 \\ 11x = 11 \\ x = 1[/tex]

therefore,

[tex]KL = 3x + 7 \\ = (3 \times 1) + 7 \\ = 3 + 7 \\ = 10[/tex]

Answer:

2√(17) or about 8.2462 units.

Step-by-step explanation:

We want to determine the distance between the two points (-10, -7) and (-8, 1).

We can use the distance formula. Recall that:

[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Substitute and evaluate:

[tex]\displaystyle \begin{aligned} d &= \sqrt{((-10)-(-8))^2 + ((-7) - (1))^2} \\ \\ &=\sqrt{(-2)^2+(-8)^2} \\ \\ &= \sqrt{(4) + (64)} \\ \\ &= \sqrt{68}\\ \\ &= 2\sqrt{17}\end{aligned}[/tex]

Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.

Solution :-

As per the provided information in the given question, we have been given that:

To calculate the distance between the two points, we will apply the formula below:

[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \: \: }}[/tex]

Substitute the given values into the above formula and solve for d:

[tex]\sf:\implies{ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}}[/tex]

[tex]\sf:\implies{d = \sqrt{[-8 - (-10)]^2 + [1 - (-7)]^2}}[/tex]

[tex]\sf:\implies{d = \sqrt{(2)^2 + (8)^2}}[/tex]

[tex]\sf:\implies{d = \sqrt{4 + 64}}[/tex]

[tex]\sf:\implies\bold{d = \sqrt{68} \approx 8.2462 \: units}[/tex]

Answer: Hello There!................

Mean = Sum of observation / total number of observation

Mean = 1.35m

1.35  = Sum of length of 7 wood planks/ 7

1.35*7 = Sum of the length of 7 wood planks

9.45 = Sum of the length of 7 wood planks

Let the length of extra added wood plank = x

So,

(Sum of the length of 7 wood planks + x) / 8 = 1.4m

(9.45 + x) / 8 = 1.4

9.45 + x = 1.4 * 8

9.45 + x = 11.2

x = 11.2- 9.45

= 1.75

So,

The length of extra added wood plank = 1.75m

Answer:

Mean>Median

Step-by-step explanation:

A right skewed distribution with no outliers will have it's mean value greater than the median ( mean > median)

A distribution is said to be right skewed if it's peak is to the left such that it has a long tail to the right.

Conversely, a distribution with it's peak to the right such that it has a long tail is said to be left skewed.

Using the analogy of a boxplot, a right skewed distribution will have it's box to the left and a longer whisker to the right. This means that the median point which is the vertical line in between the box will be lesser than the mean value.

Median < mean = mean > median

Step 1:  

To find the values of trigonometric functions of t

[tex]\sec(t)=\frac{H}{A}[/tex]

[tex]=\frac{2}{1}[/tex]

Analyze the figure and find the value of O

[tex]t[/tex] ∈ [tex]IV[/tex]

We can use those tips to solve the problem.

Option A:

4/5 is a positive slope so it will rise from left to right.

Option B:

No slope automatically means "undefined" so that falls in the definition of a vertical line.

Option C:

A slope of 0 is defined as a horizontal line.

Option D:

-4/5 is a negative slope so it will fall from left to right.

Answer:

0

Step-by-step explanation:

The * means multiplication where the ^ means exponents, so you multiply in this case.

-6 * -6 = 36

Two negatives equals a positive.

PEMDAS shows that multiplication and division occurs first so...

7 * -6 = -42

36 + -42 + 8

-8 + 8

= 0

You can search it up to see what PEMDAS is.

Answer:

10

Step-by-step explanation:

So you start with

0.10x+0.25(24-x)=4.50

First you do the parenthesis

.25x24 is 6.

So

.10x+6-.25x=4.5

Combine like terms

-.15x+6=4.5

Now isolate the x so you can find what x is

4.5-6

-.15x=-1.5

Then divide

-1.5/-.15

The two negatives make it positive

So 1.5/0.15

Comes to 10.

x=10

The 10 comes like this .15 is 15/100

Simplify that to 3/20

1.5 is 15/10

Simplify that to 3/2

Then divide those

3/2 ÷ 3/20

You cant divide fractions so flip the other side and multiply

3/2 × 20/3

60/6

10
