Four one foot rulers laid end to end reach how many inches?

Answer:A.

Step-by-step explanation:

We can see that both circles have the same radius. This means that the circles have same areas. Therefore, the area of the figure is the difference of the area of the rectangle and the sum of the area of the two circles.

The area of a rectangle is the vertical side length multiplied with the horizontal side length.

Substitute the radius in the formula to determine the area of the circle.

To determine the area of the shaded region, we need to determine the area of the square, then subtract it with the area of the circle.

The area of a square is the measure of its side, squared. Therefore,

The formula that determines the area of a circle is πr². We can tell that the radius of the circle is required to determine the area of the circle, as the formula to determine the area of a circle (πr²) includes the variable "r", which is the radius of the circle.

How to determine the radius of the circle?

Since we are given the diameter of the circle, we can determine the radius of the circle by creating an equation that represents the relationship between a diameter and radius. Then, substitute the diameter in the equation and solve for the radius of the circle.

Determining the radius of the circle:

It should be noted that the diameter is twice larger than the radius. Therefore, the equation that represents the relationship between the radius of the circle and the diameter of the circle is;

Substitute the diameter in the equation to determine the radius of the circle.

Divide 2 to both sides of the equation and simplify both sides:

Substitute the radius in the formula to determine the area of the circle.

Take π as 3.14

Answer:

B = 3

Step-by-step explanation:

4+2b = 10

= 2b = 10-4

2b = 6

b = 6/2

= 3

Answer:

b=3

Step-by-step explanation:

You start off with

4+2b=10

And you must solve for B.

Subtract 4 on both sides to balance the equation.

2b=6

Then divide both sides by 2 so B is by itself.

b=3

Then you get your answer!

Step-by-step explanation:

1 ton = 2000 ponds

Multiply: 2000x30=?

2000x30=60000

Answer:

52000 pounds

Step-by-step explanation:

On ton is equivalent to 2000 pounds.

We can use this information to set up a unit converter. See the format for a unit converter below:

[tex]\text{Unit We Have}\ \cdot\ \frac{\text{Unit We Want}}{\text{Unit We Have}}[/tex]

Substitute the given values into the equation:

[tex]26\text{ tons}\ \cdot\ \frac{2000 \text{ pounds}}{1 \text{ ton}}=26\ \cdot\ 2000 \text{ pounds}=52000 \text{ pounds}[/tex]

The truck weighs about 52000 pounds.

Answer:

it's G because 7×8×9=504

Answer:

G is the answer

Answer:

Your mode is 6 and range is 4

Step-by-step explanation:

Mode is the most popular number in the data set.

Range is the Maximum subtracted by the Minimum.

_______________________________

6, 8,6,7,6,8,6,4,6 is your data set.

The most popular number in the set is 6 which is your mode.

Your maximum is 8 and your minimum is 4.

Do 8-4

8-4 = 4.

Your mode is 6 and range is 4

Answer:

Mode: 6

Range: 4

The total amount that she paid was $410.75

Step-by-step explanation:

The taxes is 34.75%

Hope this helped

Answer:

Total Price is $410.75 and the tax rate is 0.0953

Step-by-step explanation:

Step 1:  Determine how much she paid

Initial Price of Dress + Tax on the Dress

$375.00 + $35.75

$410.75

Step 2:  Determine the tax rate

(Tax) / (Price Before Tax)

($35.75) / ($375.00)

0.0953

Answer:  Total Price is $410.75 and the tax rate is 0.0953

Answer: The solution set of the system of inequalities is the region above the dashed line (y=-2x-2) and below the solid line (y=x+4).

Please, see the attached graph.

Answer: B

Step-by-step explanation: sorry i was a year late lol

Proving congruency:

CA = CA, reflexive

m ∠DCA = m ∠BAC, alt interior  ∠

m ∠BCA = m ∠DAC, alt interior  ∠

triangle DCA = triangle BCA,   ASA

Supplementary angles means a pair of angles adding to 180 degrees.

180 degrees would be a straight angle.

∠DCA +  ∠BCA =  ∠DCB, not a straight angle.

Hope this helped.

1- b.25.135

2- E.154

3- d-452

4- A.3

5-c-380

Step-by-step explanation:

answered in the same order the images are in

A = \pi r^2

Answer:

Step-by-step explanation:

1.  (8)^2

   = 64 inch(e)

2. area of circle = 2[tex]\pi[/tex]r

                          =  2 x 3.14 x 7

                           = 43.96 ≈ 44 inch(a)

3. area of circle = 2[tex]\pi[/tex]r

                           =2 x 3.14 x 12

                            = 75.36 ≈ 78 cm^2(a)

4. area of circle = 2[tex]\pi[/tex]r

                         =  2 x 3.14 x 1

                          =    6.28 ≈ 12 cm^2(c)

5. area of circle = 2[tex]\pi[/tex]r

                          = 2 x 3.14 x 22

                           = 138.16 ≈ 138 in^2(d)

Answer:

1. median = 27

2. range = 29

3. mode = 32

4. maximum value = 41

5. interquartile range = 21

6. minimum value = 12

7. upper quartile = 35

8. mean = 25.333333333333 (repeating)

9. lower quartile = 14

Step-by-step explanation:

no

Answer:

27= median   29= range   32= mode   41= max value   21=interquartile range

12= minimum   35= upper quartile   25=mean   14= lower quartile

Step-by-step explanation:

God I love Triangles

1: b=36 units

2: C.

1st Explanation:

Given the triangle's sides are to scale, you can take the larger one and divide a side value by it's scaled version to find the rate of change.

In this instance, i took 45/10 and got 4.5, I checked with the other side and found 27/6 also was equivalent to 4.5. This meant the scale from Triangle 1 to Triangle 2 was upscaled by a multiple of 4.5 ...

I took the non-scaled side, and used the common multiple that is present on the other sides, and I found 8x4.5=36.

So, side b, the un-labeled, target side on Triangle 2, equals 36 units. (never forget  the units when written, remember this for your future.)

2nd Explanation:

The word problem presents an estimated guess that we are to evaluate it's accuracy of.

I started by reading Laamars, prediction, and checked for any obvious answers. I did not find one, so I moved on to do the math to the estimated penny, by doing:

-Lamar has 1 Full Jar worth $51.45

Value: (51.45)

-Lamar has two identical (same, nearly) jars

Value: (2x51.45)

-Lamar has a 3/4 full jar. So, I converted 3 divided by 4 to .75,

Value: (.75x51.45)

-Lamar has a 1/2 full jar. So, I used one half of 51.45 with the equation: Value: (51.45/2 OR .5x51.45)

So, gathered the values and got the sum of:

Estimated Value = 51.45+(51.45x2)+(.75x51.45)+(.5x51.45) = $218.66

With this in mind, we know Lamar OVERESTIMATED, so we can eliminate answer choices A and B. When you read D, it is already known that the exact value may not be $51.45, so, by process of elimination, I concluded that Lamar most likely overestimated becuase "He has Just over 4 containers, and 4x50=200"

3+.75+.5=4.25, so the statement "just over 4" is true.

Answer:

y = |x-1| - 5

Step-by-step explanation:

To shift the graph to the right, you need to subtract from the inside of the absolute value sign.

Answer:

y=|x-5|-5

Step-by-step explanation:

the -5 inside the absolute value determines whether it is left or right, so we need to subtract five to move five to the right. Ok, so i'm pretty sure this is really confusing trust me i think it's correct
