The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is Fraction 2 over 5 unit and the width is Fraction 1 over 5 unit, what is the perimeter of the rectangle in units?

Answer:

if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.

less dense

more dense

Answer:

10. 16 cubic cm

11. 5 and 1/3 cubic cm

Step-by-step explanation:

4 · 4 · 2 = 32

32 times 1/2 = 16

2 · 2 · 4 = 16

16 times 1/3

Answer:

10: The volume is 2[tex]cm^{3}[/tex]

11: The volume is [tex]\frac{8}{27}[/tex][tex]cm^{3}[/tex]

Step-by-step explanation:

Question 10: ([tex]\frac{1}{2}[/tex] * 4)([tex]\frac{1}{2}[/tex] * 2)([tex]\frac{1}{2}[/tex] * 2) = 2 * 1 * 1 = 2[tex]cm^{3}[/tex]

Question 11: ([tex]\frac{1}{3}[/tex] * 4)([tex]\frac{1}{3}[/tex] * 2)([tex]\frac{1}{3}[/tex] * 1) = [tex]\frac{4}{3}[/tex] * [tex]\frac{2}{3}[/tex] * [tex]\frac{1}{3}[/tex] = [tex]\frac{8}{27}[/tex][tex]cm^{3}[/tex]

Answer:

9 inches

Step-by-step explanation:

A = bh

A = 108

b = 12

108 = 12h

108/12 = h

9 = h    so the height is 9 inches

Answer:

$42.00

Step-by-step explanation:

20% OF  50 = 40

Before Tax Price: $40.00

Sale Tax: 5.00% or $2.00

After Tax Price: $42.00

Answer:

$42

Step-by-step explanation:

To get the new bench price, you multiply 50 × 0.2, which gets you 10, then you subtract 50-10, which is 40, and $40 is the price of the bench on sale. (You could also do 50 × 0.8 to avoid a step and still get the same answer).

You then take 40 and multiply is by 0.05 to get the tax, which would be $2. From here, you add 40+2 to get $42, the amount of money Presley paid for the bench.

Answer: 91.46m

Step-by-step explanation: The length of 100 yard football field in meters. From the dimension given, 1 yard = 3 feet Therefore, 100 yard = x feet 1 yard = 3 feet 100 yard = x feet X = (100 × 3) / 1 X = 300 feet. But, 1 meter = 3.28feet X meter = 300 feet X = (300 × 1)  3.28X  = 91.46m Therefore, 100 yard football field is equal to 91.46m

Answer: LCD = 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/12, 7/18

For the denominators (8, 12, 18) the least common multiple (LCM) is 72.

LCM(8, 12, 18)

Therefore, the least common denominator (LCD) is 72.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 9/9 = 9/72

1/12 = 1/12 × 6/6 = 6/72

7/18 = 7/18 × 4/4 = 28/72

Answer:

$14.00 - $9.10 = $6.90

Step-by-step explanation:

Answer:

Supposed that you needed to know the diagonal distance from opposite corners of a rectangular prism.

d^2=x^2+y^2+z^2  where x, y, and z are the dimensions of the prism, or rectangular "box"

If the box has a width of 10, depth of 20, and a height of 30 then you have:

d^2=100+400+900

d^2=1400

d^2=100*14

d=√(100*14)

d=10√14 units

d≈37.42 units  (to nearest hundredth of a unit)

You might need this information to determine the most amount of space necessary to allow this box to pass through in any orientation...as the diagonal is the maximum dimension of the box.

I did a three-dimensional problem as the Pythagorean Theorem is often used only for two-dimensional problems in early mathematics.

Answer:

/

Step-by-step explanation:

Answer:

-no solution-

Step-by-step explanation:

When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.

you plug in that variable to the other equation

8x - 2(4x + 20) = -20

and then you just solve the equation from there.

8x - 8x + 20 = -20

but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.
