Answer: 10

Step-by-step explanation: The answer is 10 because xy means x times y, and since x = 10 and y = -2, 10 times -2 equals -20. Now you have to divide that by --2 which is just 2. So -20/2 equals -10. -10's absolute value is 10. Thus the answer is 10.

Answer:

D. the length is 18 inches and the width is 9 inches.

Step-by-step explanation:

Given information:

Therefore, to find the actual dimensions of the lawn, multiply the given scale dimensions by 15:

⇒ Length = 6 × 15 = 90 in

⇒ Width = 3 × 15 = 45 in

If the gardener's partner plans to make another scale drawing of the lawn with a different scale of 1 : 5, to find the dimensions of his scale drawing, divide the actual dimensions by 5:

⇒ Length = 90 ÷ 5 = 18 in

⇒ Width = 45 ÷ 5 = 9 in

Therefore, the dimensions of his scale drawing are the length is 18 inches and the width is 9 inches.

An alternative way to approach this problem is to calculate the difference between the two scales.  It is clear that the original scale of 1 : 15 is 3 times the new scale of 1 : 5.  Therefore, simply multiply the original dimensions by 3 to find then new dimensions of the scale drawing with a scale of 1 :5.

Answer:

y=4x

Step-by-step explanation:

if you look at the line you'll see it takes 4 x's to = 1 y, every time you go right 1 you go up 4

Answer:

The slope is 4.

Step-by-step explanation:

Step 1:

Slope can also be found by using the formula, Y2-Y1/X2-X1

In this case, our first point is the origin, so x would be 0 and y would be 0. On the second point, our x is -1, and our y is -4.

So, we can make the solution, -4-0/-1-0.

You can simplify this into, -4/-1, and then into 4.

Therefore, the slope is 4.

Step 2:

M is our slope, so in our y=mx equation our m = 4.

If you substitute in the m, you get y=4x.

Answer:

y=4x.

Hope this helped!

First step, make ratios:

Pages: time

Sheldon: 9 pages: 15 minutes

Betty: 18 pages: 60 minutes (1 hour)

To find how long it would be for 360 you divide:

9/15 is 0.6 pages: 1 minute and 18/60 is 0.3 pages per minute

When you make the table here would be the equation:

y=.06x for Sheldon and y=.3 for betty (plug in times and create a table)

Answer:

not similar

Step-by-step explanation:

Answer:

Step-by-step explanation:

I would say not similar because they both don't have the same length and width but if you're talking about the shape itself then I would say similar because they are both quadrilaterals and trapezoids.

Step-by-step explanation:

The options 1,2 and 5 are the correct answer.

The given equation is 1.23/[tex]10^1[/tex]=0.123.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Now,

1) 1.23/[tex]10^1[/tex]=0.123

Here LHS=RHS

2) 123/100=1.23

Here LHS=RHS

3) 12.3/[tex]10^0[/tex]=1.23

⇒ 12.3/1=12.3

So, LHS≠RHS

4) 0.123/10=1.23

⇒ 0.123/10 = 0.0123

So, LHS≠RHS

5) 1230/10³=1.23

⇒ 1230/1000

= 1.23

Here LHS=RHS

Therefore, the options 1,2 and 5 are the correct answer.

Answer:top one is a

second one is c

nuber 3 is c

4 is b

Step-by-step explanation:

Answer:

1. x >= 4

2. x /= -4

3. The first one

4. The second one

Step-by-step explanation:

1. Since the bolded arrow is pointing to numbers greater than 4, we can tell that x is greater than 4. The dot on the number 4 is colored, meaning that four is included, thus x is greater than or equal to 4.

2. Since the bolded areas are on every point on the graph except -4, we can tell that x is every number but -4, thus x is not equal to -4.

3. The sign "<" indicates that x is less than 3. This eliminates the second option. Since there is no equal to sign, the dot isn't colored, thus, the first one.

4. The sign "<=" indicates that x is less than or equal to -1, eliminating the third option. Since it is equal to, the dot should be colored, thus, the second one.

Answer: 5:1

Example : Not really explanation but here is an example ^^

What is the scale factor between 4 cm and 10 cm ?

4 and 10 are divisible by 2

Length A : 4 ÷ 2 = 2

Length B : 10 ÷ 2 = 5

so the scale factor from A to B is 2:5

Explanation:

Each term inside is raised to the fourth power.

The rule is (ab)^c = a^c*b^c

An example:

(2*3)^4 = 6^4 = 1296

(2*3)^4 = 2^4*3^4 = 16*81 = 1296

Therefore, (2*3)^4 = 2^4*3^4

Step-by-step explanation:

0.857142 repeated

:)

Answer:You just divide the original amount by 100 (move the decimal point over two places)

750 / 100 = 7.5

Now you multiply that by the interest rate, which in this case is 7.

7.5 x 7 = 52.5

Now finally, you multiply that by the amount of years. In this case, 3.

52.5 x 3 = 157.5

That would be the amount added after three years! Remember, this is simple interest. Compound interest is a little more complex.

Step-by-step explanation: I hope this helps.

For this equation the easiest thing to start with ratios:

16:4 (scale of 4 due to 4 x 4 being = to 16)

For the y-2 to find y you first will put 8/4 (your scaling back), so 2 so 4-2 would be 2 which makes that equal to y.

Knowing that 8 is the size on the one side these are equal on the top so x-3 had to equal 8, so 11-3=8 so...

x=11

y=2
