heya! could someone tell me what the rate change of the table here is?

Answer:

28 kwh

Step-by-step explanation:

given that the care can travel 5 miles on 1 kwh, i.e

5 miles travelled -----> uses 1 kwh

hence to find the unit rate:

1 mile travelled ----> Uses 1 kwh ÷ 5 = 1/5 kwh

We are also given that Helen lives 70 miles away from her aunt.

Hence a return trip (i.e "to aunts house and back"), will be 70 x 2 = 140 miles

using the unit rate that we found above, we can find the number of kwh that is used to travel 140 miles

140 miles = 140 miles x unit rate

= 140 x 1/5

= 28 kwh

Answer:

Part A

Scale factor

= 1 : 175

Part B

52.5 mm

Part C

99.4%

Step-by-step explanation:

Justin is working with a microscope that magnifies objects to 175 times their actual size.

Part A

Enter a number in each box to determine the scale factor for the microscope.

= 1 : 175

Part B

The diameter of an amoeba cell is 0.30 millimeter. How big will the cell appear to Justin under the microscope?

Scale factor =

1 : 175

Diameter of the Amoeba cell = 0.3mm

1mm = 175 mm

0.3mm = x

Cross Multiply

x = 0.3 × 175

x = 52.5 mm

Part C

What is the percent increase of the area of the amoeba cell under the microscope?

Increase = 52.5 mm - 0.3mm

= 52.2 mm

Percent increase

= 52.2/52.5 × 100

= 99.4%

Answer:

Median; mean.

Step-by-step explanation:

A data set consists of 2, 2, 3, 4, 5, 5, and 7. Then, 20 is added to the data set. The new value will have little effect on the median, but it will raise the mean significantly.

Let's find the median and mean from the original data;

x = 2, 2, 3, 4, 5, 5, 7.

F(x) = 2 + 2 + 3 + 4 + 5 + 5 + 7

F(x) = 28

[tex] Mean = \frac {F(x)}{7} [/tex]

[tex] Mean = \frac {28}{7} [/tex]

Mean = 4

Median is the middle number of a sorted array of numbers.

Median = 4

Now, let's find the median and mean from the new data;

x = 2, 2, 3, 4, 5, 5, 7, 20.

F(x) = 2 + 2 + 3 + 4 + 5 + 5 + 7 + 20

F(x) = 48

[tex] Mean = \frac {48}{6} [/tex]

Mean = 8

[tex] Median = \frac {4 + 5}{2} [/tex]

Median = 4.5

Therefore, the median increased from 4 to 4.5 while the mean increased significantly from 4 to 8.

Answer:

m=11

Step-by-step explanation:

Add 19 to both sides.

3m−19+19=14+19

3m=33

Divide both sides by 3.

3m/3=33/3

m=11

Answer:

m=11

Step-by-step explanation:

We want to isolate m on the left side of the equation.

3m-19=14; add 19 to both sides, now you have:

3m=33; divide 33 by 3:

m=11

Answer:

The function Has to Be Linear.

Step-by-step explanation:

The reason why the function has to be linear is because even though there is a slight curve the rest of the line is straight.

You need to look at the direction the line is pointing. Now say it was a line that had all kinds of wavey curves and loops that would be nonlinear.

I hope this helps you out. Let me know if linear is the correct answer, because if it isn't then that Assessment is crazy.

Answer:

Each people get 20,000 mili-litres of water.

Step-by-step explanation:

As , we know that

1 litre = 1000 mili-litre

As we have 80 litre of water

⇒ 80 litres = 80×1000 mili-litres

                 = 80,000 mili-litres

⇒ 80 litres = 80,000 mili-litres

∴ we have

Total water available in the crew = 80,000 mili-litres

As , there are 4 people in the crew

Let each people consume x mili-litre

⇒4x = 80,000 mili-litres

⇒x = [tex]\frac{80,000}{4} = 20,000[/tex] mili-litres

∴ we get

ANSWER:123

Step-by-step  its  very simple its puttin x+11 is how u get ur answer by adding the numbers close to that one angle

The measure of the seventh angle in the heptagon is 125 degrees.

A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.

We are given the measures of six angles in the heptagon, which are:

95, 107, 132, 138, 145, and 158 degrees

Sum of angles in Heptagon is 900 degrees.

To find the measure of the seventh angle, we can subtract the sum of the six known angles from the sum of all the angles in the heptagon:

Measure of the seventh angle = Sum of angles - Sum of known angles

Measure of the seventh angle = 900 degrees - (95 + 107 + 132 + 138 + 145 + 158) degrees

Measure of the seventh angle = 900 degrees - 775 degrees

Measure of the seventh angle = 125 degrees

Therefore, the measure of the seventh angle in the heptagon is 125 degrees.
