The difference would be 100 because if you subtract 847 and (747=100) it will equal one hundred.

Answer:

The difference is 100.

Step-by-step explanation:

8 forty- sevens = 847

7 forty-sevens = 747

Now, we have to find the difference between 8 forty- sevens and 7 forty-sevens ,that means we will subtract 7 forty-sevens from 8 forty-sevens.

$847-747$

= 100

Therefore, the difference is 100.

Find the measure of line f and g

kiruha [24]

In this case we use intersecting secant theorem

According to this theorem, GF*GE = GH*GA

So,we plug in the values

(x-3)*(x-3+9) =(x-2)*(x-2+6)

(x-3)*(x+6) =(x-2)*(x+4)

x^2 +6x -3x -18 =x^2 +4x -2x -8

x^2 +3x -18 =x^2 +2x -8

x^2 +3x -18 -x^2 -2x +8 =0

x -10 =0

x=10

So,FG =x-3 = 10-3 =7

The cost, in millions of dollars, for a company to manufacture x thousand speed boats is given by the function C(x) = 3x2 - 30x

nalin [4]

Answer:

5000

Step-by-step explanation:

In vertex form, the cost function is ...

C(x) = 3(x² -10x) +175 = 3(x² -10x +25) +175 -3(25)

C(x) = 3(x -5)² +100

The vertex is at x=5, so the cost function will be minimized when 5000 speed boats are produced.

Irina-Kira [14]

Answer:

1380 households in Gettysburg are likely interested in using lawn care services

Step-by-step explanation:

To solve this question, we find the sample proportion and estimate for the entire population.

Sample proportion of households in Gettysburg that are likely to be interested in using lawn care services?

92 of 92 + 51 + 17 = 160 households.

92/160 = 0.575

Based on his results, how many households in Gettysburg are likely interested in using lawn care services?

Sample proportion of 0.575.

For the entire population of 2400 households:

0.575*2400 = 1380

1380 households in Gettysburg are likely interested in using lawn care services

Lucia is wrapping packages that are in the shape of a triangular prism. The net of the prism is shown below: ( Help me answer th

solniwko [45]

Answer:

The total surface area of all 6 prisms is 6336 in^2.

Step-by-step explanation:

Let's find the surface area of ONE prism and then multiply that result by 6 to obtain the final answer.

One prism:

The area of the two 13 in by 26 in rectangular tabs is 2(13 in)(26 in), or 676 in^2 (subtotal);

The area of the two triangles of base 10 in and height 12 in is 2([1/2][10 in][12 in], or 120 in^2; and, finally,

The area of the 10 in by 26 in base is 260 in^2.

The total surface area of ONE prism is thus:

676 in^2 + 120 in^2 + 260 in^2, or 1056 in^2.

Now, because there are 6 of these prisms, multiply this last result by 6:

6(1056 in^2) = 6336 in^2.

The total surface area of all 6 prisms is 6336 in^2.
