Answer:

6.4%

Step-by-step explanation:

Given:

Productivity of new machine = 12% greater than last model

Number of new machines = -5%

Let's take number of machines = n

Take p as productivity of each machine.

Total productivity = np.

Productivity of new machine will be:

(100% + 12%) * p

= 112%.p

= 1.12p

Number of new machines will be:

(100% - 5%) * n

= 0.95n

From the calculations, total productivity will now be

1.12p * 0.95n

= 1.064np

Percentage Change in total productivity will be:

= \frac{new productivity - old productivity}{old productivity} * 100

= \frac{1.064np - np}{np} * 100

Converting np to 1 (or any number of your choice), we have:

= \frac{(1064*1)-1}{1} * 100

= 6.4%

Therefore, the percentage change = 6.4%

The total number of produced details increased by 6.4%

suppose the starting number was x. 
suppose x=100
100 +12%= 112
112-5%=106.4
106.4-100=6.4
6.4%

Rectangle with a width of 36 centimeters and a perimeter of 80 centimeters
olga2289 [7]

Answer: Height = 4 centimeters

Area = 144 cm^2

Step-by-step explanation:

So we know that on a rectangle opposite sides are equal in distance.

If one side of the rectangle is 36 centimeters then that means the opposite side is also 36 centimeters.

36 + 36 = 72 centimeters

The perimeter is the sum of all sides, so two out of the four of our sides total to 72 centimeters. So the remaining length of both sides is as follows:

80 - 72 = 8

The sum of the remaining sides is 8 so divide it between the two and that is the height.

8/2 = 4

I'm not sure what the question wants so here is pretty much everything:

Height: 4 cm

Area: 144 cm^2

Answer:

7.4*10^-5, 7300000

Step-by-step explanation:

1 There are 4 zeros in 1

round up .0000742 to .000074

There are 5 places between 7 and the last zero, negative because it is a decimal.

2 7.3*10^6= 73 is first, 6 places after 7 so 5 zeros (6 is in a place)

If <br> B is the midpoint of AC, AB=x+6 and AC=5x-6, then what is BC?
nikklg [1K]

If B is the midpoint of AC, then AB=BC. It is also BC=AC-AB

AB = x + 6

AC = 5x - 6

BC = (5x - 6) - (x + 6)

We can kinda use distributive property, like this:

BC = 5x - 6 -x - 6

Combine like terms:

BC = 4x - 12

To verify, we can add AB and BC to see if their sum is equal to AC.

(x + 6) + (4x - 12) = 5x - 6

If we are correct, this equation will be true.

x + 6 + 4x - 12 = 5x - 6

Combine like terms:

6 + 5x - 12 = 5x - 6

5x - 6 = 5x - 6

It's correct!

BC = 4x - 12. Final Answer.

Let me know if you have any questions about this! :)

An architect drew the blueprint for a new office building. He used a scale in which 1 inch represents 7.5 feet. The floor of an
Hoochie [10]

Answer:

C.

2.67 inches by 2.27 inches

Step-by-step explanation:

We can use ratios to solve

1 in        x inches

-------- = ---------

7.5 ft       20 ft

Using cross products

1*20 = 7.5x

Divide each side by 7.5

20/7.5 =7.5x/7.5

2.67 =x

We can do the same for the other dimension

1 in        x inches

-------- = ---------

7.5 ft       17 ft

Using cross products

1*17 = 7.5x

Divide each side by 7.5

17/7.5 =7.5x/7.5

2.27 =x

2.67 inches by 2.27 inches
