A rectangle has an area of 12 square centimeters and a perimeter of 16 centimeters. which of the following couldd be its dimensions?

a. 2 cm and 6 cm
b. 3 cm and 8 cm
c. 1.5 cm and 8 cm
d. 1 cm and 12 cm

Answer: 240



Step-by-step explanation: 8 x 10 = 80 and 8 x 20 = 160 so 80 + 160 = 240

Answer: the answer is 240

Step-by-step explanation:

first you multiply 10 by 8 (10 times 8) then you multiply 8 by 20 (8 times 20)  then add the two answers 80 + 160=?...

for help use L*w*h ( length times width times height)

Answer:

Step-by-step explanation:

"Which ordered pair" implies that there were several answer choices for this problem.  It's important that you share such answer choices.

2x+4y=6x−y reduces to 5y = 8x, and so y = (8/5)x

If we choose x = 2, then y = (8/5)(2) = 16/5 is a solution of the given equation.  There are an infinite number of such solutions.  All lie on the line y = (8/5)x.

Answer:

Step-by-step explanation:

you don't have the option to what the drop downs say so I'm giving my best guess as to what they all say based on context.

-----------------------------------------------------------------------------------

Data Set B has distant outliers, so it has a lower MAD.

The smaller MAD of Data Set A suggests that most of the data is less than the mean that is in Data Set B

However, most of the data in Data Set A is (unknown) spread out from the mean than in Data Set B

Therefore, MAD is not reliable when there is an outlier.

------------------------------------------------------------------------------------

I am unsure if these fit the answers the drop-downs give but they make the most sense given the context.

Answer:

Vertical angles

5 and 7

supplementary angles

6 and 7

Step-by-step explanation:

Here we are to give a pair of vertical angles.

What they mean here is two angles which are equal because they are vertically opposite.

Such an example here is angles 5 and 7

Example of angles that are supplementary

when two angles are supplementary, they add up to be 180

Since the sum of two angles on a straight line equals 180, what this means is that any of those two angles that are beside each other on a straight line add up to be 180

One of such examples is 6 and 7

Answer:

Step-by-step explanation:

To make long equation simpler to simplify

Inverse operation can be used to cancel out terms, which can be used to simplify the expression. Example:

\(x^2 = 9\)

taking the inverse of this by taking teh square root

\(\sqrt(x^2) = \sqrt(9) = 3\)

Part A: first multiply 2 by x and -3 → combine all like terms → Add 6 on both sides → subtract 6x from both sides.

Your final answer should be -5

step by step:    4x + 2(x-3) = 4x + 2x - 11

                          4x +2x -6 = 4x + 2x - 11

                                            6x -6 = 6x - 11

                                            6x = 6x -11 +6

                                            6x = 6x -5

                                            6x-6x= -5

                                            0 = -5

Part B: Add all like terms.

Answer:

320cm³

Step-by-step explanation:

to find the area of the rectangular prism we can use the formula V= LWH

6×8×5=240 cm³

to find the area of the triangular prism we use the formula V=1/2LWH

4×8×5×1/2=80cm³

240+80=320

Answer:

320cm³

Step-by-step explanation:

First, find the area of the triangle.

a=hb/2 (area = height * base / 2)

area = 4*8/2=16

Then, find the area of the rectangle.

a=wl (area = width * length)

area = 6*8=48

Then, you add the two totals and multiply the width (5cm).

16+48=64

64*5=320

Answer:

The answer is 1,067.

Answer:

 1067

Step-by-step explanation:

using DMAS rule

2×4×152+643-264/2×6

1216+643-132×6

1859-792

1067

Irrational means it cannot be written as a fraction of two integers.

1/6 is a fraction, so that's out.

0.060606... can be written as a fraction because it's a repeating decimal, so that's out.

\(\sqrt{49}=7\) and 7 can be writen as the fraction 7/1, so that's out.

The answer is \(\sqrt{17}\).

Answer:

10 sushi rolls can be made.

Explanation:

we can use division to find the number of sushi rolls:

\(\boxed{\frac{2\frac{1}{2} }{\frac{1}{4} } }\)

\(\boxed{\frac{\frac{5}{2} }{\frac{1}{4} } }\)

\(\frac{5}{2} * \frac{4}{1}\)

\(\frac{20}{2}\)

\(10\)

Here the mathematical operation to find the number of sushi rolls is division.

Answer:

\(V = 904.32 in^3\)

Step-by-step explanation:

From the comments on this question, I see that the radius is 6 inches;

Hence, we have:

Given

Shape: Sphere

Radius = 6

Required

Volume

Volume of a sphere is calculated as thus;

\(V = \frac{4}{3} \pi r^3\)

Where V and r represent volume and radius

Substitute 6 for r and 3.14 for π

\(V = \frac{4}{3} \pi r^3\) becomes

\(V = \frac{4}{3} *3.14 * 6^3\)

\(V = \frac{4}{3} *3.14 * 216\)

\(V = \frac{2712.96}{3}\)

\(V = 904.32 in^3\)

Hence, the volume of the sphere is; \(V = 904.32 in^3\)

Answer:

(2,2)

Step-by-step explanation:

Answer:

A'= (-2.5,1)

Step-by-step explanation:

To find the coordinates of A, multiply the original coordinates by the scale factor.

A= (-5,2)

A'= (-5/2,2/2)

A'= (-2.5, 1)

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.
