Answer:

Step-by-step explanation:

2 + 3 + 11 = 16

Perfect squares that are lower than 16 and 9, 4, and 1.

We can't find 3 prime numbers that add up to 9, 4, or 1.

Answer:

19 is the smallest prime number that is the sum of three different prime number.

Step-by-step explanation:

To find this:

2 is the only even prime number and other prime numbers are odd

adding any two prime number always gives even number.

so the least numbers that are required to do is 3,5 and 7; their sum is 15

so any prine number less than 15 is not possible for this question

so, the next prime number is 17

17 minus any other prime no less 17 are13,11,7.5.3,2 give the number that 4,6,10,12,14,15 which are not sum of any two different prime numbers

so the answer is 19=11+5+3.

You have a summer job that pays time and half over time ( if you work more than 40 hours) after that is 1.5 times you hourly rat

olga55 [171]

Answer:

Step-by-step explanation:

Having a job that pays at $7 per hour is quite nice. And the question says that if he does overtime, he gets 1 and a half times the normal price of $7. This means that, for every overtime he works, he will get paid at

7 * 1.5 = $10.5

The question didn't state what, but if it's anything to go by the wages expected to be paid then I'd say the job isn't worth it if it's overly stressful. I said so because most jobs out there aren't really about the workers, but the money instead.

Desde la cuspide de un faro de 50m de altura sobre el nivel del mar se observa que el angulo depersion a un bote velero es de 20

poizon [28]

Answer:

137.4 meters

Step-by-step explanation:

In this case, they give us the height of the lighthouse that corresponds to 50 meters and the depression angle is 20 °, in this case we can apply the tangent trigonometric function, which relates the opposite side to the adjacent side.

tan a ° = opposite / adjacent

the horizontal that is formed would be the adjacent side, therefore if we solve we are left with:

horizontal distance = opposite / tan to °

replacing, we are left with:

hd = 50 / tan 20 °

hd = 50 / 0.3639

hd = 137.4

the horizontal distance is equal to 137.4 meters

6x+1=4x+19 ...........

Luda [366]

Do I understand coorectly, you have the following equation

6x+1=4x+19

and you want to know what x is?

first, let's put all the expressions with x on one side and all else on the other side:

6x-4x=19-1

and calculate this 2x=18

and divide by 2:

x=9

and this is the answer!
