Since below and to the right is in the FOURTH QUADRANT
So,
<span>(4 - i) is in the FOURTH QUADRANT. </span>

If D varies directly with t and D is 105 when t is 3 find D when t is 8

gladu [14]

If D varies directly with t and D is 105 when t is 3 then value of D when t is 8 is equal to 280

<u>Solution:</u>

In this sum we have been given that there is a direct relationship between d and t.

If d is 105 when t is 3 so now, we need to find d when t is 8.

To do this we can simply use the unitary method. The definition of unitary method is, the unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, according to the definition we need to find the value of d when t is 1.

This can be done as follows:

$D=\frac{105}{3}=35$

Therefore, the value of d when t = 1 is 35.

Now, if the value of t=8 then d becomes:

$D=35 \times 8=280$

Hence, when t=8 the value of d is 280.

You have decided to wallpaper your rectangular bedroom. the dimensions are 12 feet 6 inches by 10 feet 6 inches by 8 feet 0 inch

Papessa [141]

The wall area is the product of the room perimeter and the room height:
A₁ = (2*(12.5 ft + 10.5 ft))*(8.0 ft) = 368 ft²

The window and door area together is
A₂ = 2*((4 ft)*(3 ft)) + (7 ft)*(3 ft) = 45 ft²

The area of one roll of wallpaper is
A₃ = (2.5 ft)*(30 ft) = 75 ft²

Then the number of rolls of wallpaper required will be
1.1*(A₁ - A₂)/A₃ ≈ 4.74

5 rolls of wallpaper should be purchased.

_____
As a practical matter, not much of the window and door area can be saved. The rolls are 30 inches wide, but the openings are 36 inches wide. Some will likely have to be cut from two strips. The strips will have to be the full length of the wall, and the amount cut likely cannot be used elsewhere. If the window and door area cannot be salvaged, then likely ceiling(5.4) = 6 rolls will be needed (still allowing 10% for matching and waste).

1. Government laws require that new showerhead flow rates be no more than 2.5 gallons per minute. If you take one 10-minute show

bagirrra123 [75]

25 gallons of water used in a day by a leaky faucet.

3,78,500 drips of water used in a day by a leaky faucet.

400 cups of water used in a day by a leaky faucet.

Here, we have given that:

2.5 gallons = 1 minute

10 minutes = 1 shower

1 shower = 1 day

1. In 1 day, we are taking 10 minutes shower

now, in 10 minute we are using 2.5 x 10 = 25 gallons of water.

means we are using 25 gallons of water in 10 minutes of shower.

2. Yes, I agree with my classmates.

No, the amount of water wasted by the leaky faucet over the course of 1 day is not closer to the estimate of 1 cup, 1 gallon or 1 least shower.

3. Least faucet has wasted 25 gallons of water in 1 day.

As we have given 1 gallon = 15,140 drips

so, in 25 gallon = 25 x 15,140 = 3,78,500 drips

also 1 gallon = 16 cups

so in 25 gallon = 25 x 16 = 400 cups

4. A. Yes, my classmates conjecture is true.

5. 25 gallons of water used in a day by a leaky faucet.

Hence,

25 gallons of water used in a day by a leaky faucet.

3,78,500 drips of water used in a day by a leaky faucet.

400 cups of water used in a day by a leaky faucet.

Bro SOME ONE PLS HELP ME FIND X i am HORRIBLE at math tutor meeee

Damm [24]

B. 10+3x=5

3x=-5 (subtract 5 both sides)

X=. -5/3 (divide both sides by 3)

C. A+x = b

X = b-a (just get x alone)

D. Cx = d

X = d/c
