the sum of all internal angles=(sides-2)*180
720=(x/25-2)*180
4=x/25-2
6=x/25
150=x degrees per angle of A

use angle of A to calculate amount of sides of A:
150=(n-2)*180/n
150=180-360/n
360/n=30
12=n=sides of A
-> F

Donald=500-6*t
Wendy=400-4*t
W=D
500-6t=400-4t
100-6t=-4t
100=2t
50=t
-> A

The ratio of men to women working for a company is 4 to 7.If there are 52 men working for the company, what is the total number

11Alexandr11 [23.1K]

143 employees

Because

4 to 7 means that for every 4 men, there is 7 women.

To figure this out I first divided 52 by 4

52÷4=13

I then multiplied this number by 7

13×7=91

Now knowing there are 91 women I added them together

91+52=143

The mayor of a town places a map of the town on a coordinate grid with Town Hall at the point (0,0) and with each unit represent

Lorico [155]

Answer:

Given that the question rightly asks the amount it cost to drive from Smithville to Jones City, we have;

The question rightly asks the amount it cost to drive from Smithville to Jones City is approximately $7.209

Step-by-step explanation:

The coordinates of Smithville is (-25, 10)

The coordinates of Jones City is (15, 12)

The cost of driving a car for a mile = $0.18

Therefore, the distance from Smithville to Jones City is given by the formula for the distance, l, between two points with coordinates as follows;

$l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}$

Where;

(x₁, y₁) = (-25, 10) and (x₂, y₂) = (15, 12)

$l = \sqrt{\left (12-10 \right )^{2}+\left (15-(-25) \right )^{2}} = 2 \cdot \sqrt{401}$

The distance from Smithville to Jones City = 2·√401 ≈ 40.05 miles

The amount, A, it cost to drive from Smithville to Jones City a distance of approximately 40.05 miles is therefore given as follows;

A = 40.05 miles × $0.18 ≈ $7.209

The probability of a certain brand of battery going dead within 15 hours is. Noah has atoy that requires 4 of these batteries. H

Delicious77 [7]

Question:

The probability of a certain brand of battery going dead within 15 hours is 1/3. Noah has a toy that requires 4 of these batteries. He wants to estimate the probability that at least one battery will die before 15 hours are up.1.Noah will simulate the situation by putting marbles in a bag. Drawing one marble from the bag will represent the outcome of one of the batteries in the toy after 15 hours. Red marbles represent a battery that dies before 15 hours are up, and green marbles represent a battery that lasts longer.How many marbles of each color should he put in the bag? Explain your reasoning.

Answer:

The number of marbles of each color that should be present in the bag is;

1 red marble and 2 green marbles

Step-by-step explanation:

Here, we note that the probability of a battery going dead = 1/3 and the

Therefore if the red marbles represent that a battery dies before 15 hours then the probability of picking the red marble should be 1/3. That is if there is only one red marble in the bag, the probability of picking the red will be 1/3 when there are other 2 green batteries in the bag

That is there should be 1 red marble and 2 green marble in the bag.
