Step-by-step explanation:

The area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².

Area of circle = πr², where radius is r.

Thus, given that a circle has radius (r) = 1 units

Area of the circle = π(1²) = π units²

If the radius is given as r, the area of the circle remains as πr².

Therefore, the area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².

Step-by-step explanation:

(a-b)² = (a-b)×(a-b) = a²-b²

Answer:

No they are not

Step-by-step explanation:

squaring that expression will come out to be a^2-2ab+b^2

this is because you are doing (a-b)(a-b), so you have to multiply each term from the first set of parenthesis by each term in the second set of parenthesis.

a^2-ab-ab+b^2

a^2-2ab+b^2

(a-b)^2≠a^2-b^2

Answer:

1: $3.40     2: $34.00

Step-by-step explanation:

you take 0.34 and multiply it by how many stamps you have. So in this case you have 10 stamps for #1 so you move the decimal over to the right once (since one step is a tenth) and you have $3.40 and for 100 stamps you restart with 0.34 and move the decimal over to the right twice since that would be one-hundredths, and you would get 34. or when you add the units $34.00

Answer:

40

Step-by-step explanation:

The value of a right angle is 90° and <SQR is a fraction of <PQR.

Hence,  <PQS, which is the other fraction of <PQR, equals 90-50 and 90-50 is 40.

Or we can do it like this;

⇒ 180-90-50

⇒ 90 - 50

⇒ 40

Thus, Answer is 40.

Step-by-step explanation:

I got it wrong then it gave me the right answer of 1/2

The fraction of the sweaters that cost $50 or less is 50% is 1/2.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

From the box plot,

Median = $50

Now,

Median = $50

This means,

50% of the clothes are above $50 and 50% of the clothes are below $50.

Now,

The fraction of the sweaters that cost $50 or less is 50%.

So,

= 50/100

= 5/10

= 1/2

Thus,

The fraction of the sweaters that cost $50 or less is 50% is 1/2.

Answer:

The equation a + d(n-1)

Step-by-step explanation:

Where a is the first number in the sequence, d is the common difference and n is the position of a certain number in the series, e.g

1, 2, 3, 4, 5: a = 1, d = 1 (because 2-1=1, 3-2=1, 4-3=1, etc) and n = 1,2,3...

2, 4, 6, 8, 10: a = 2, d = 2 (because 4-2=2, 6-4=2, etc) and n = 1,2,3,4,5...

So for the second sequence, we could try to get the value of n in n = 6 as follows:

a + d(n-1) where a = 2, n = 6 and d = 2

Thus, 2 + 2(6-1) = 2 + 2(5) = 2 + 10 = 12

So the sixth number in the series would be 12

Step-by-step explanation:

the standard measure for speed is

miles per hour.

now we got as measurement

3 miles per 1/4 hour.

to give the standard speed or "unit rate" we assume that the bicyclist maintains the same speed for a whole hour.

and the question is : how many miles is he traveling then in that 1 hour ?

to answer this we have to check how often the actually measured unit of time fits into 1 hour.

1/4 hour fits 4 times into 1 hour.

and that factor applies now also to the miles to keep the value of the rate or ratio unchanged :

miles/time × a/a = miles×a/(time×a)

so that (time×a) = 1 hour

and so, he traveled 3×4 = 12 miles per hour.

Step-by-step explanation:

i hope my math is right lol

Answer:

135 masks

Step-by-step explanation:

First, we take $997 and subtract that by $349

$997 - $349 = $648

To find how many masks Elena can print, we divide $648 dollars by $4.80. Since one mask is equivalent to $4.80

$648 ÷ $4.80 = 135

Answer:  x = 0.421053y+5.263158

Step-by-step explanation:

x = 0.421053y+5.263158

Answer:

x=0.042105y+10/19

Step-by-step explanation:

Let's solve for x.

19x−0.8y=10

Step 1: Add 0.8y to both sides.

19x−0.8y+0.8y=10+0.8y

19x=0.8y+10

Step 2: Divide both sides by 19.

19x/19=0.8y+10/19

x=0.042105y+10/19

Answer:

-88 and -87

Step-by-step explanation:

Since the two unknown integers are consecutive, one will be one more than the other. This means we can express them as x and x+1, so we only have one unknown in our equation. Since they add to -175, we can now write our equation:

x+(x+1) = -175

Take away brackets and combine like terms:

2x+1 = -175

Now we just need to isolate x which we can do by subtracting 1 from both sides and then dividing both sides by 2:

2x+1-1=-175-1

2x = -176

2x/2 = -176/2

x = -88

And our other number is -88+1 = -87

So our two numbers are -88 and -87 which are consecutive and add to 176:

-88+(-87) = -175

Work Shown:

C = 2*pi*r

6.28 = 2*3.14*r

6.28 = 6.28r

6.28r = 6.28

r = (6.28)/(6.28)

r = 1

The radius of the circle is 1 yard.

A = pi*r^2

A = 3.14*1^2

A = 3.14

The area is roughly 3.14 square yards.

The area of the trampoline  is mathematically given as

a = 3.14

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference   is mathematically given as

Answer: D) The linear model shows a strong fit to the data

The actual strength of the relationship is unknown unless we have the actual values of each data point (so we can compute the correlation coefficient r), but the residuals are randomly scattered about both above and below the horizontal axis. This means we have a fairly good linear fit. If all of the points were above the line, or all below the line, or all residuals fit a certain pattern (eg: parabola), then it wouldn't be a good linear fit.
