Answer 1

Answer:

we know that

The rate of the Relationship is the slope of the function

Find the slope of the Relationship A

the slope is equal to

$m=((y2-y1))/((x2-x1))$

we have the points

$(4,2)\ and\ (8,4)$

Substitute in the formula above to find the slope

$m=((4-2))/((8-4))$

$m=(2)/(4)=0.5$

Compare the value of the rate of the Relationship A with each case

case a)

$y = (3/4)x$

In this case the rate of the equation is equal to $(3)/(4)$

Compare with the rate of the Relationship A

$(3)/(4)>(2)/(4)$

therefore

$y = (3/4)x$ -----> This equation could represent Relationship B

case b)

$y = (0.6)x$

In this case the rate of the equation is equal to $0.6$

Compare with the rate of the Relationship A

$0.6 > (2)/(4)$

$0.6 > 0.5$

therefore

$y = (0.6)x$ -----> This equation could represent Relationship B

case c)

$y = (2/3)x$

In this case the rate of the equation is equal to $(2/3)$

Compare with the rate of the Relationship A

$(2)/(3) >(2)/(4)$

Multiply by $12$ both sides

$8 > 6$

therefore

$y = (2/3)x$ -----> This equation could represent Relationship B

case d)

$y = (1/4)x$

In this case the rate of the equation is equal to $(1/4)$

Compare with the rate of the Relationship A

$(1)/(4) <(2)/(4)$

therefore

$y = (1/4)x$ -----> This equation could not represent Relationship B

therefore

the answer is

$y = (3/4)x$

$y = (0.6)x$

$y = (2/3)x$

during a 20%of sale,the sale price of an mp3 alarm clock was 35.96 what was the regular price of the radio

Answers

If 20% was taken off, that means that 35.96 is 80% of the original price.
35.96 = $(80)/(100)$
Now, we just need to put it into fractions, cross multiply, and divide to find the original price.
$(35.96)/(1) = (80)/(100) \$
35.96×100 = 3596
1×80 = 80
3596÷80 = 44.95
Now, to make sure, we multiply 44.95 by 20%,
44.95×0.20 = 8.99
Subtract that from 44.95
44.95-8.99 = 35.96
That is the sale price of the alarm clock.
This means that yes, the regular price of the mp3 alarm clock was
$44.95

If the product of two positive fractions a and b is 15/56, find three pairs for possible values for a and b

Answers

Answer

Find out the three pairs for possible values for a and b .

To prove

As given

$The\ product\ of\ two\ positive\ fractions\ a\ and\ b\ is\ (15)/(56) .$

i.e it is written in the form.

$a* b = (15)/(56)$

When

$a = (3)/(2) , b = (5)/(28)$

Than

$(3* 5)/(2* 28) = (15)/(56)$

When

$a = (3)/(4) , b = (5)/(14)$

Than

$(3* 5)/(4* 14) = (15)/(56)$

When

$a = (1)/(2) , b = (15)/(28)$

Than

$(1* 15)/(2* 28) = (15)/(56)$

Hence proved

all you have to do is find pairs of factor for both 15 and 56
e.g. 1,15 3,5
1.56 2, 28 4, 14

so three possibilities could be
1/1 x 15/56
3/4 x 5/14
1/2 x 15/28

The diameter of the jar of marshmallow fluff is 5in. What is the area of the jar opening? Please show the steps how to do that.

Answers

The opening of the jar is a circle.

The area of any circle is (pi) x (radius)²

What's the radius of the jar ?
Well, the diameter is 5 inches.
Radius = 1/2 of the diameter = 2.5 inches.

So Area = (pi) x (2.5 inches)² =

(3.14) x (6.25 square inches) = 19.625 square inches.

Final answer:

The area of the jar opening, being a circle, is found by using the formula A = pi*r^2. With a diameter of 5, the radius is 2.5. So the area is approximately 3.14 * 2.5^2 = 19.625 square inches.

Explanation:

To calculate the area of the jar opening, which is a circle, you need to know the radius of the circle. The given information is that the diameter is 5 inches. The radius is half the diameter, therefore, in this case, the radius is 5/2 = 2.5 inches. Then to find the area, you use the formula for the area of a circle: A = pi * r^2, where pi is approximately 3.14 and r denotes the radius. Substituting the known values into the formula, we have Area = 3.14 * (2.5^2) = 3.14 * 6.25 = 19.625 square inches. Thus, the area of the jar opening is approximately 19.625 square inches.
