Answer:

Yes 4.25 is a rational number

Answer: Yes, 4.25 is a rational number

Any terminating decimal can be written as a fraction of two integers.

In this case, 4.25 = 4.25/1.00 = 425/100

Answer:

(7,0)

Step-by-step explanation:

By Multiplying 4 and 7 (aka x), it will equal 28.

Multiplying 9 and y, (aka 0) , it will equal to 0

4(7)+9(0)=28

multiplying -4 by 7 will equal to -28 ,minus y which is 0, total will be -28

So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.

Hope it helped :)

The original price was $15.00

The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:

18 = x × (1 + 20%)

18 = x × 1.20

18 = 1.20x

x = 18 / 1.20

x = $15.00

In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

When it comes to fat, there's one type you don't want to cut back on: omega-3 fatty acids. Two crucial ones -- EPA and DHA -- are primarily found in certain fish. ALA (alpha-linolenic acid), another omega-3 fatty acid, is found in plant sources such as nuts and seeds. Not only does your body need these fatty acids to function, but also they deliver some big health benefits.

Answer:

No, the slope's are not the same

Short-cut explanation:

Simply count the spaces between the two lines at the very top then compare to the number of space between at the very bottom of the graph.

There are 2 spaces between the two lines at the top. There seems to be 1 and 1/2 spaces at the very bottom.

[tex]2\neq 1.5[/tex] , therefore, not parallel.

If they are the same, then it is parallel. Although, in this case, it is not(Shown on the graph).

Answer:

Basic Concept:

A criterion for parallel lines is that they should have equal slopes. If the slopes of these lines is equal, these lines are parallel and are intersecting if the slopes are not equal

let the line on the left be 'line 1' and the line on the right be 'line 2'

Slope of Line 1:

We are given 2 points on the line and we will use them to get its slope

We know that the slope of a line is the change in its y-ordinate divided by its change in x - ordinate

The points given are:      (-3 , -5)              and           (0 , 4)

Change in x:

The change in x of these 2 coordinates can be calculated by subtracting their x- ordinates

Change in x (Δx) = x1 - x2

Δx = -3 - 0

Δx = -3

Change in y:

The change in y of these 2 can similarly be calculated by subtrating the y-ordinates

change in y (Δy) = y1 - y2

Δy = -5 - 4

Δy = -9

Slope of the line:

Since the slope = Δy / Δx

Replacing the known values:

Slope = -9 / -3

Slope = 3

Therefore, the slope of 'line 1' is 3

Slope of Line 2:

We are given 2 points on the line and we will use them to get its slope

We know that the slope of a line is the change in its y-ordinate divided by its change in x - ordinate

The points given are:      (0 , -6)              and           (4 , 4)

Change in x:

The change in x of these 2 coordinates can be calculated by subtracting their x- ordinates

Change in x (Δx) = x1 - x2

Δx = 0 - (4)

Δx = -4

Change in y:

The change in y of these 2 can similarly be calculated by subtrating the y-ordinates

change in y (Δy) = y1 - y2

Δy =  -6  - 4

Δy = -10

Slope of the line:

Since the slope = Δy / Δx

Replacing the known values:

Slope = -10 / -4

Slope = 5/2

Therefore, the slope of 'line 2' is 5/2

Conclusion:

We have calculated the slope of both the lines.

now, we will compare the slopes to find out if the lines are parallel or not

Slope 1 = 3

Slope 2 = 5/2

Since the slopes are NOT equal, the lines are not parallel

Step-by-step explanation:

the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"

because this is just a matter of definition. the function itself would not suggest any limits.

and in that regard the function definition is basically irrelevant.

the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.

so, the second set of definitions is not possible, if we are really trying to define the inverse function.

Step-by-step explanation:

They are like terms meaning they all have the same variable you can just add them.

4c+c+6c

11c

Answer:

11c

Explanation:

We are given the expression:

4c+c+6c

We can simplify by combining like terms.  All three terms have a “c” so they can all be combined.

Factor out a “c” and add the coefficients.

4c+1c+6c

(4+1+6)c

(11)c

11c

4c+c+6c simplified is 11c

So assuming he bought the entire 29 calculators he would've spent:

[tex]29 \times 3.85 = 111.65[/tex]

That leaves him with,

[tex]200 - 111.65 = 88.35[/tex]

Looking back at the prices i'm assuming there is no way he can reach 99 calculators with what he has left, so i will establish an equation that defines the number of calculators he can buy with the remaining £88.35.

Let c be the number of calculators he can still buy. Note that we are working in the 30-99 range so each calculator costs £3.65

[tex]88.35 = 3.65c[/tex]

[tex]c = \frac{88.35}{3.65} = 24.2[/tex]

So now we know he can still buy 24 calculators in addition to the 29 calculators, so in total he bought,

[tex]29 + 24 = 53[/tex]

Your answer would be 53 calculators.

What about the 0.2 remaining 'calculators',well that would be left over money which aren't sufficient to purchase an additional calculator+we were working with the 30-99 range meaning each one costs £3.65

[tex]0.2 \times 3.65 = 0.73[/tex]

So he bought 53 calculators and has 0.73£ remaining.

Answer:

r = 1.7389 in

Step-by-step explanation:

(A) Volume of hollow block = 540 in^3

(B) volume of block without Hollows = b×d×h

= 6 ×16 ×8

= 768 in^3

(C) volume of 3 hollows = 3 ×( pi ×r^2 h)

= 3 ×( pi ×r^2 ×8)

= 24 ×pi ×r^2

solve,

A = B - C

540 = 768- (24 ×pi ×r^2)

r^2 = (768- 540) / 24 pi

r = root(3.023943919)
