Mathematics
1 answer:
vfiekz [6]3 years ago
3 0

Answer:

B. PK = 15, RJ = 9

Step-by-step explanation:

RQ = 3

PQ = 5

✔️In ∆JKL, Q is the centroid. According to the centroid theorem, thus:

⅓(RJ) = RQ

⅓(RJ) = 3

Multiply both sides by 3

RJ = 3*3

RJ = 9

✔️Also, based on the centroid theorem,

⅓(PK) = PQ

⅓(PK) = 5

Multiply both sides by 3

PK = 5*3

PK = 15

We conclude that the profit if the company produces 10 units is 1,040 dollars.

<h3></h3><h3>How to find the profit?</h3>

The profit is defined as the difference between the revenue and the costs.

In this case, we know that the revenue and costs are defined by:

R(x) = 200x - 5x^2

C(x) = 360 + 6x

Then the profit equation is:

P(x) = R(x) - C(x).

P(x) = 200x - 5x^2 - (360 + 6x)

P(x) = -5x^2 + 194x - 360

Now we want to find the profit when x = 10, then we will get:

p(10) = -5*10^2 + 194*10 - 360 = 1,040

We conclude that the profit if the company produces 10 units is 1,040 dollars.

Jayanta is raising money for the? homeless, and discovers each church group requires 2 hr of letter writing and 1 hr of? follow-
boyakko [2]

Answer:

Jayanta needs 2 labor union groups and 8 church groups.

Step-by-step explanation:

Let c denotes churches .

Let l denotes labor unions.

We know that Jayanta can only spend 20 hours letter writing and 14 hour of follow-up.

So, equations becomes:

2c+2l=20

c+3l=14

And total money raised can be shown by = 150c+175l

We have to maximize 150c+175l keeping in mind that 2c+2l \leq 20 and c+3l \leq 14

We will solve the two equations:  2c+2l=20 and c+3l=14

We get l = 2 and c = 8

And total money raised is 150\times8 + 175\times2 = 1200+350=1550 dollars.

Hence, Jayanta needs 2 labor union groups and 8 church groups.

A tower made of wooden blocks measures​ 114 feet high. Then a block is added that increases the height of the tower by 8 inches.
satela [25.4K]

Answer:

4. 23 in

Step-by-step explanation:

The tower is 1 1/4 feet high, then 8 inches are added. Well, we can't just add those two numbers. We have to change the units! Change everything to inches.

1 1/4 feet is equal to 12 inches + 3 inches = 15 inches, because a foot = 12 inches.

Add 8 inches to 15, and you get 23 inches.

<u>The answer is 4. 23 in. </u>
