Answer:

x = 110

Step-by-step explanation:

This shape is a heptagon. A heptagon's interior angles add up to 900 degrees. You can solve for x by finding the sum of all known values, and subtracting that sum from 900.

105 + 150 + 140 + 135 + 125 + 135 = 790

900 - 790 = 110

Answer:

it's the haptagon so it's sum of all sides is equall to900 degree

so first add the side accept x and subtract it with 900 degree

the answer will be 110 degre

Step-by-step explanation:

The mean of a set a score is simply the average score.

  To find the mean, simply sum the individual scores and divide by the total number of scores;

  Mean of a  set of score  = [tex]\frac{Total scores}{Number of scores}[/tex]

Another way to find the mean is using:

   Mean  = [tex]\frac{summation of all f(x)}{summation of all the frequency}[/tex]

Multiply the frequency of each score with the score and divide by the sum of all of the frequency.

2. The median is the middle score;

 Arrange the data set from the lowest to the highest, the median is the one that falls in the middle.

If there are two numbers find their sum and divide by 2.

Step-by-step explanation:

55 berries     1700 berries

--------------- = -------------------

1 jar                   x jars

Using cross products

55x = 1700*1

Divide each side by 55

55x/55 = 1700/55

x = 1700/55

Changing to a mixed number

55 goes into 1700 30 times

30 *55 =16501700-1650 = 50

x = 30 50/55 = 30 10/11

There are 50 berries left over

S=− [tex]\frac{4}{Q}[/tex]

Step-by-step explanation:

−5=(QS)−1

Swap sides so that all variable terms are on the left hand side.

QS−1=−5

Add 1 to both sides.

QS=−5+1

Add −5 and 1 to get −4.

QS=−4

Divide both sides by Q.

[tex]\frac{QS}{Q}[/tex]=[tex]\frac{-4}{Q}[/tex]

Dividing by Q undoes the multiplication by Q.

S= [tex]\frac{-4}{Q}[/tex]

Divide −4 by Q.

S=− [tex]\frac{4}{Q}[/tex]

Answer:

12 noon

Step-by-step explanation:

Clock 1 loses 3 minutes every 2 hours. Now, 2 hours = 120 minutes.

This means, it has speed of 120 - 3 = 117 minutes for every 2 hours.

Thus, in 1 hours, it's speed = 117/2 = 58.5 min/hr

Clock 2 gains 3 minutes every 4 hours

Which means in an hour, it gains ; 4/3 minutes

Thus, it's speed an hour is; 60 + 4/3 = 61.333 min/hr

Now, When he returns home in less than two weeks, the clocks show the same time.

let's say the number of hours he was away is x. For the 2 clocks to show the same time, it means they have to show it by 12 noon at another day since it was at noon that he set the correct times before leaving.

Thus, they will both be showing 12 noon.

Answer:

6 [tex]\frac{3}{4}[/tex]

Answer:

If a function is increasing, the average rate of change between any 2 points must be positive.

If we have an increasing function, the average rate of change between any two points must always be positive.

For an increasing function f(x), we have that if:

b > a

Then:

f(b) > f(a).

Now, we define the average rate of change on an interval (a, b) as:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, because:

b > a

f(b) > f(a)

Then:

b - a > 0

f(b) - f(a) > 0.

So both numerator and denominator are positive, which implies that the quotient must be positive.

Then, if we have an increasing function, the average rate of change between any two points must always be positive.

Answer:

$100.25

Step-by-step explanation:

This question says that 5 shirts cost $60.90, so you would divide the two numbers to find out the price of 1 shirt

$60.90÷5=$12.18

Then you would just solve this equation

T=$12.18x+$14.99

T= Total Money Spent

x= Number of Shirts

Plug in the 7 shirts and solve

T=$12.18(7)+$14.99

T=$85.26+$14.99

T=$100.25

Answer:

A. V/B=H B. The height, h, is 6 cm.

Step-by-step explanation:

A. Rearrange the formula V=Bh by dividing both sides by B to isolate h.

B. Plug in the Volume and Base into your rearranged formula to find the height. 216/36= h. h=6

a. The formula for height is h = V/B.

b. The height of the pyramid is 6 centimetres.

The total surface area of a pyramid is the surface area of the triangular sides in addition to the surface area of the triangular base.

According to the given question we have the volume of the pyramid which is 216 cm³ and base is also given which is 36 cm.

Given V = Bh

∴ h = V/B.

h = 216/36

h = 6 cm.
