Answer:

777,223 meters squared

Step-by-step explanation:

To find the amount of carpeting, we must find the area of the floor of Tom's bedroom.

To find area, we multiply the length and width of the rectangle.

999 x 777 = 776,223

Remember, when we find the area, we must give the answer in square units.

Our final answer is 777,223 meters squared

Radda [10]

The number of dodgeballs Ttaloc pumped up is 20.

The number of other balls Ttaloc pumped up is 36.

The orginal number of the total ball is 14.

<h3>What are ratios?</h3>

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

The number of dodgeballs Ttaloc pumped up = (5/14) x 56 = 20

The number of other balls Ttaloc pumped up = (9/14) x 56 = 36.

A company produces three different types of wrenches: W111, W222, and W333. It has a firm order for 2,000 W111 wrenches, 3,750 W
lawyer [7]

Answer:

z (min) =  150090.8    ( monetary units )  ( $ )

x₁  =  2000     x₄  = 0     x₂  =  3382   x₅  =  368   x₃ = 0  x₆ = 1700

Step-by-step explanation:

wrenches produced in-house   ( W111 = x₁   W222 = x₂  W333 = x₃ )

x₁      x₂    and  x₃

wrenches produced outside  (W111 = x₄  W222 = x₅  W333 = x₆ )

x₄     x₅    and  x₆

Objective function:

z  =  17*x₁  +  20.40*x₄  +  19*x₂  + 21.85*x₅ + 23*x₃ + 25.76*x₆   to minimize

First constraint: Manufacturing hours: 16500

2.5*x₁  +  3.4*x₂  +  3.8*x₃   ≤  16500

Second constraint: Inspection hours : 1600

0.25*x₁  +  0.3*x₂  +  0.45*x₃  ≤ 1600

Three demands constraint:

x₁    +   x₄   =  2000

x₂   +  x₅    =  3750

x₃   + x₆     =  1700

x₁  ≥  0     x₂  ≥   0     x₃  ≥  0   x₄  ≥  0   x₅  ≥  0   x₆  ≥  0    all integers

After 6 iterations with on-line solver the solution is:

z (min) =  150090.8    ( monetary units )  ( $ )

x₁  =  2000     x₄  = 0     x₂  =  3382   x₅  =  368   x₃ = 0  x₆ = 1700

Section 1 - Question 1
xenn [34]

Value of 5(d–2) is 45.

Option C is correct.

Step-by-step explanation:

We are given 3(d+1)=4(d–2) and we need to find the value of 5(d–2)

First we will solve 3(d+1)=4(d–2)  to find value of d:

Solving:

3(d+1)=4(d–2) \\3d+3=4d-8\\3d-4d=-8-3\\-d=-11\\d=11

So, value of d = 11

Now putting value of d in 5(d–2) and finding its value:

5(d–2)\\=5(11-2)\\=5(9)\\=45

So, value of 5(d–2) is 45.

Option C is correct.

Determine the area of the figure shown. Note that each square unit is one unite in length
liq [111]

Answer:

74 units squared

Step-by-step explanation:

we know that the area of a square or rectangle is A = L × w

so we should just separate the object into it's individual rectangles/squares, solve for their areas, then add them together.

so I'll start with the middle square its length is 8 and width is 8 too.

A = 8 × 8

A = 64

now we'll move on to the other small ones to the side.

the one on the right side it's length is 2 and width is 2.

A = 2 × 2

A = 4

and then the last one on the left, Length is 3, width is 2.

A = 2 × 3

A = 6

now we'll add up all of the areas to get the total area.

Total = 64 + 4 + 6

Total = 74 units squared
