The length of a rectangle is 7 cm longer than its width.

The area of the rectangle is 120 cm².

What is the width of the rectangle?

Enter your answer in the box.

Answers

Answer:

length = 15 width = 8

Area 15x8 = 120

Step-by-step explanation:

L = length

W= width

L = W + 7 (width plus7)

Area = W x L

Area =W (W+7)

Do the distribution:

120 = W ² + 7W

Subtract 120 on both sides

W + 7W -120 = 0

Factor it

(W + 15)(W - 8) = 0

W = -15 or W = 8

8 is used for W

L = W + 7

L = 8+7=15

Length = 15

Width =8.

There are 8 big fish for every___
small fish.
There are 4 big fish for every___
small fish.

The image is attached any way pls someone i beg u help me.

Answers

Answer and Step-by-step explanation:

We have to use the image to help us answer this question.

We see that there are 8 big fish in the tank, and 10 small fish in the tank.

So, for the first part, it would be:

There are 8 big fish for every 10 small fish.

For when there are 4 big fish, we need to divide 10 by 2, since 8 divided by 2 is 4.

10 ÷ 2 = 5

So,

There are 4 big fish for every 5 small fish.

Use the original price and the markup to find the retail price.
Original price: $70; Markup: 15%

Answers

The gross profit P is the difference between the cost to make a product C and the selling price or revenue R.
P = R - C
To calculate revenue R based on the cost C and the desired gross margin G, where G is in decimal form:
R = C / ( 1 - G)
The gross profit dollars P is the revenue dollars R from the sale times the gross margin G percentage, where G is in decimal form :
P = R * G
The markup percentage M, in decimal form, is gross profit P divided by cost C.
M = P/ C
M * 100 will change the decimal to a percentage.

Answer:

$80.50

Step-by-step explanation:

To find the retail price:

Find 15% of $70. 0.15 × $70 = $10.50Add the markup price to the original price. $70 + $10.50 = $80.50Final answer - $80.50

Suppose you randomly select a sample of 16 observations from a population with =11 and =2 You find ⎯⎯⎯=9. The sampling error is _____ -2 2 -1 1

Answers

Answer:

- 2

Step-by-step explanation:

Given that :

Population mean, μ = 11

Population standard deviation, σ = 2

Sample mean, xbar = 9

Sample size, n = 16

The sampling error could be explained as the variation or difference which exists in statistical measure of the population and sample as the sample data does not totally or wholly represent the population data. This difference in sample and population mean is called sampling error.

Hence, the sampling error in the above scenario can be obtained thus :

Sampling error = (xbar - μ)

Sampling error = 9 - 11 = - 2

A circle fits in a square with sides of 12 inches. What is the approximate area of the shaded region between the square and the circle? (Use 3.14 for Pi and round to the nearest whole number.) A circle inside of a square with side lengths of 12 inches. The circle has a diameter of 12 inches. 31 inches squared 69 inches squared 106 inches squared 125 inches squared

Answers

Answer:

31 inches squared

Step-by-step explanation:

Area of shaded part = area of square - area of circle

area of square = length²

12² = 144

Area of a circle = πr²

r = radius = 12/2 = 6

(3.14) x 6² = 113.04

Area of shaded part = 144 - 113.04 = 30.96

rounding off to the nearest whole number gives 31

Use limits to find the area between the curve of y = x and the x-axis for the interval from
x= 1 to x= 3.
Links will be reported.

Answers

Answer:

The area between the curves is 4 square units.

Step-by-step explanation:

We want to find the area bounded by:

y = x

x = 0

in the interval x = 1, x = 3

This is simply equal to the integral of the function f(x) = x between x = 1 and x = 3

Written as:

[tex]\int\limits^3_1 {x} \, dx[/tex]

And the integral of x is equal to x^2/2

Then:

[tex]\int\limits^3_1 {x} \, dx = (\frac{3^2}{2} - \frac{1^2}{2}) = (\frac{9}{2} - \frac{1}{2} ) = \frac{8}{2} = 4[/tex]

The area between the curves is 4 square units.

0 -2

4 10

Answers

Answer:

y=3x-2

Step-by-step explanation:

We know the equation ends in -2 because when x is zero, y is -2

To find the rest of the equation take any other point and take away the -2 from y

Then divide the y by the x to see how may times larger (or smaller) the y is then the x

(I chose -14)

-12÷-4=3

y=3x

the put the -2 back at the end because otherwise, your -14 would be a -12 and that is not a point on the table

In order for a neuron to receive and transmit a message it must be in a polarized state. While in this rest state there are more sodium ions outside the cell membrane while potassium is prevalent inside the cell. This causes the neuron to maintain a neutral charge. Once the action potential arrives at its [ Select ] , a nerve cell will shuttle the message down its own axon and to the next neuron via its [ Select ] . This impulse will cause the cell to become [ Select ] and will effectively change the charge of the neuron to a [ Select ] charge. After sodium rushes into the cell, the potassium will rush out in order to [ Select ] . Once the impulse reaches the axon terminal, it is [ Select ] that stimulates a [ Select ] to continue the message to the next neuron.
