Y=AB-8. Trying to learn how to solve for A.

Answers

Answer:

[tex]A=\frac{Y+8}{B}[/tex]

Step-by-step explanation:

So we have:

[tex]Y=AB-8\\[/tex]

First, add 8 to both sides. The right will cancel:

[tex]Y+8=AB[/tex]

Now, notice that A is multiplied to B. So, the isolate A, divide both sides by B. The right will cancel:

[tex]A=\frac{Y+8}{B}[/tex]

And we're done!

Hey There!! ~

The answer to this is: the upper bound for the length is [tex]21.5cm.[/tex] Lower and Upper Bounds

The lower bound is the smallest value that will round up to the approximate value.

The upper bound is the smallest value that will round up to the next approximate value.

Ex:- a mass of 70 kg, rounded to the nearest 10 kg, The upper bound is 75 kg, because 75 kg is the smallest mass that would round up to 80kg.

Here , A length is measured as 21cm correct to 2 significant figures. We need to find what is the upper bound for the length . let's find out:

As discussed above , upper bound for any number will be the smallest value in decimals which will round up to next integer value . So , for 21 :

⇒  [tex]21.5cm.[/tex]

21.5 cm on rounding off will give 22 cm . So , the upper bound for the length is [tex]21.5cm.[/tex]

A rope 5 meters long was cut into 7 equal parts. What is the length of each part?

Answers

Answer:

5/7 meters

Step-by-step explanation:

Take the 5 meters and divide into 7 parts

5/7 = 5/7 meters

To find the length of each part, we can divide.

5 / 7 = 0.714...

We can just keep it as a fraction.

The answer is 5/7m

What are the coordinates of G, H, and I after a rotation about (0,0) by 90 degrees clockwise? Thank you.

Answers

Answer:

Ok, when we have a point (x, y) and we do a rotation of 90° the new points will actually depend on the quadrant where we are, but it will always change the order to (y, x) but this does not end here, because depending on the quadrant where the point ends, the signs will change as follows.

1st quad (+y, +x)

2nd quad (-y, +x)

3rd quad (-y, -x)

4th quad (+y, -x)

So if we are in the second quadrant, the transformed point will be in the first quadrant

Now, we have that the points G and H are:

G = (-1, 3)

This point is in the second quadrant, so it moves to the first quadrant (where bot values must be positive).

The new point will be:

G´ = (3, 1)

And the other point is:

H = (-4, 0)

It also rotates to the first quadrant, so the new point will be:

H' = (0, 4)

Answer:

Because the person above already explained I’ll just give the answers.

Step-by-step explanation:

G = (-1,3) H = (-4,0) I = (3,-2)

1. Explain how measurements taken by standard rulers and scales are limited,
2. Include two to three examples to demonstrate these limitations. Include at least one limitation of using
a ruler and at least one limitation of using a scale,
3. Make sure to write your answer using five to ten complete sentences,

Answers

Answer:

Please find the answer in the explanation

Step-by-step explanation:

RULER

measurements taken by ruler can be limited due to absolute errors, zero error and uncertainties.

1.) If the end of the ruler is worn out giving rise to a zero error

2.) The calibration of the ruler may give rise to another systematic error if the makings are incorrect.

3.) If the object to be measured is not on the same level as graduated surface of the ruler, the angle at which the scale is viewed will affect the result. This is known as parallax error.

SCALE

Systematic error can occur in a scale when the scale is wrongly calibrated.

Also, reading a scale from different angles introduces a variable parallax error.

random uncertainty could be a parallax error caused by taking readings from different angles. This can be reduced by the use of a mirror behind the scale and viewing normally.

The federal tax code allows some items used for business purposes to be depreciated. That is, their taxable value decreases over time. A new van used in your delivery business has a taxable value of $22,000. The tax code allows you to depreciate this van by $1900 per year. Find a formula that gives the taxable value T, in dollars, of the van after n years of depreciation.

Answers

Answer: T = 22,000 - 1,900n

Step-by-step explanation:

Taxable value is $22,000

The tax code allows for the depreciation of this van by $1,900 per year.

After n years therefore the total depreciation is;

= 1,900 * n

This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.

Formula is therefore;

T = 22,000 - 1,900n

it's easy it's called Two-way tables please help

Answers

Answer: The filled out table is shown below in the attached image

===========================================================

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

--------------

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

----------------

So we have these values

A = 40B = 26C = 14D = 21E = 19F = 4G = 17H = 9 J = 10

A rectangle’s base is 6 cm longer than its height. The rectangle’s area is 135 cm2. Find this rectangle’s dimensions. You must include units with your answers

Answers

Area of a rectangle  =  length x height

Area = 135

Height = X

Lenght = x +6

135 = x * x+6

Simplify:

135 = x^2 +6x

Subtract 135 from both sides:

x^2 + 6x - 135 = 0

Solve:

2 numbers when added need to equal 6 and when multiplied equal -135

x = 9 and x = -15

The height can't be a negative number so the height is 9

Length =  9 +6 = 15

Height = 9cm, Length = 15 cm

In the Atlanta metropolitan area, 723 new cases of invasive cancer of the cervix occurred among white women between 1975 and 1984, inclusive. An estimated 620,000 white women lived in this area on average during this time period. What is the average annual incidence rate of invasive cervical cancer in this population?

Answers

Answer:

1.166 per 1000 of population

Step-by-step explanation:

Given the following :

Newly recorded cases of invasive cervical cancer = 723

Period of time = 1975 - 1984 ( inclusive)

Estimated average Population of white women in the area at the time = 620,000

Average annual. Incidence rate invasive of cervical cancer in the population.

Incidence rate = (new cases / total population) × 10^n

Incidence rate = (723/620000) × 10^n

= 0.0011661

= 1.166 per 1000 of population

On one map of a town , the scale from the town to the map is 12mi to 3 cm. the school is 2.5cm from the grocery store on this map. on a different map of the same town ,the scale from the town to the map is 12mi to 2cm .the school is 1.5cm from the library on that map. is the grocery store or library closer to the school?

Answers

Answer:

Step-by-step explanation:

Grocery Store

12 mi / 3 cm = x / 2.5 cm            Cross multiply

12 * 2.5 = 3 * x                             Multiply

30 = 3x                                        Divide by 3

30/3 = x

x = 10 miles

Library

12 mi / 2 cm = x / 1.5                  Cross multiply

12 * 1.5 = 2x

18 = 2x                                        Divide by 2

18/2 = x

9 miles

The library is closer than the grocery store.
