What is the surface area of the rectangular prism?

36 cm²

108 cm²

72 cm ²


54 cm²

Answer:

x=7

Step-by-step explanation:

y=mx

5.5=m×11

5.5÷11=m

m=1/2

y=mx

3.5=1/2×x

3.5÷1/2=x

x=7

Answer:

x =7

Step-by-step explanation:

The direct variation equation is y = kx, where k is the constant of proportionality.

If y = 5.5 when x = 11, we can write 5.5 = 11k, which, when solved for k, yields k = 0.5.  

Then the direct variation equation in this case is y = 0.5x.

If y = 3.5, what is x?  y = 0.5x becomes 3.5 = 0.5x, yielding x = 7

Answer:

44 square inches.

Step-by-step explanation:

radius of the base = 5.5 inches

height of the cylinder = 4 inches

The shape of the vertical cross section of the cylinder through the center of the base would give a rectangle with length of 2r, and its width is the height of the cylinder.

Area of the vertical cross section = height x diameter

diameter of the cylinder = 2r

                                        = 2 x 5.5

                                        = 11 inches

The diameter of the cylinder is 11 inches.

Area of the vertical cross section = 4 x 11

                                        = 44 square inches.

The area of a vertical cross section of the cylinder through the center of the base is 44 square inches.

Answer:

11 ft

Step-by-step explanation:

The formula for the area of a rectangle of length L and width W is

A = L * W.  

Represent the length, L, by 2W + 1 ("1 more than twice the width").  Then the area formula (above) becomes:

A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:

2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}.  Let's use the quadratic formula to solve this for W:

The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441.  The square root of 441 is 21.  Thus, the quadratic formula gives us:

        -1 ± 21

W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2

            2(2)

A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.

Then, according to the formula for L that we found earlier, L  = 2W + 1, or

L = 2(5) + 1, or L = 11.

Check:  Does L * W result in an area of 55 ft²?  Yes

The length dimension of the rectangle is 11 ft

Answer:

$7.34

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Remaining decimal : $1.34 - $1 = $0.34

$7 + $0.34 = $7.34

Answer:

x^2 + 3x

Step-by-step explanation:

just add like terms so 3x^2 - 2x^2 = x^2 and 11x - 8x = 3x

Answer:

  (c) 108 yd

Step-by-step explanation:

For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...

  c² = a² +b²

Solving for c, we have ...

  c = √(a² +b²)

  c = √(40² +100²) = √(1600 +10000) = √11600

  c ≈ 107.70 . . . . yards

The length of the hypotenuse is about 108 yards.

Answer:

tan x = [tex]\frac{f}{e}[/tex]

sin x = [tex]\frac{f}{d}[/tex]

cos x = [tex]\frac{e}{d}[/tex]

Step-by-step explanation:

tan x = [tex]\frac{opposite}{adjacent}[/tex]

tan x = [tex]\frac{f}{e}[/tex]

sin x = [tex]\frac{opposite}{hypotenuse}[/tex]

sin x = [tex]\frac{f}{d}[/tex]

cos x = [tex]\frac{adajcent}{hypotenuse}[/tex]

cos x = [tex]\frac{e}{d}[/tex]

Answer:

80%

Step-by-step explanation:

Given that Of the 45 staff members at SEMS ,9 were out with the flu one day in January, it means that the number of people at work

= 45 - 9

= 36

As a percentage,

= 36/45 * 100%

= 4/5 * 100%

= 80%

The percent of the teachers were at work today is 80%

Answer: c. 3d + 15

Step-by-step explanation:

Mr. Torres paid d dollars for each of the three chairs which gives the expression of:

= 3 * d = 3d

He then paid with an amount that was greater than this 3d and got a change of $15.

That total amount that he paid is therefore, the price of the three chairs added to the $15 that he received back.

= 3d + 15

Answer:

3   19/35

Step-by-step explanation:

2+1=3

1/7+2/5 will turn out to be 5/25+14/35 because of the common denominator of 35

5+14=19

3  19/35

Answer:

Step-by-step explanation:

Area of a Semi Circle

Area = 1/2 pi r^2

r = d/2

r = 3/2

r = 1.5

Area = 1/2 3.14 * 1.5^2

Area = 1/2 * 3.14 * 2.25

Area =                                                           3.5325

Area of Rectangle

L = 12 Yd

W = 4 Yd

Area = L * W

Area = 12 * 4  =                                          48

Total Area =                                               51.5325
