Answer:

29.) D

31.)  145 girls

32.) 13,986  ,  13,967

Step-by-step explanation:

For 29 you need to find the total cost of each item. 2x1 would be $2 for the water, 1x3 would be $3 for the sandwich. Remember what operation you used to find the products. In this case, it would be D.

For 31 you need to find the number of girls at the tournament. For that you would write out the total cost of children, and subtract the number of boys from that to get the total.

For 32 you just need 2 random numbers that will round up to 14,000. Any number that is 5 or above will round up, and any number that is 4 and under will round down.

Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively. How many times will t
Evgen [1.6K]

Answer:

60 times will they ring together at the same second in one hour excluding the one at the end.

Step-by-step explanation:

Given : Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively.

To find : How many times will they ring together at the same second in one hour excluding the one at the end?

Solution :

First we find the LCM of 3, 6, 10, 12 and 15.

2 | 3  6  10  12  15

2 | 3  3   5   6  15

3 | 3  3   5   3  15

5 | 1    1  5   1    5

  | 1    1   1   1     1

LCM(3, 6, 10, 12,15)=2\times 2\times 3\times 5

LCM(3, 6, 10, 12,15)=60

So, the bells will ring together after every 60 seconds i.e. 1 minutes.

i.e. in 1 minute they rand together 1 time.

We know, 1 hour = 60 minutes

So, in 60 minute they rang together 60 times.

Therefore, 60 times will they ring together at the same second in one hour excluding the one at the end.

Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle. The height from the ground to the top of the ramp 6. 0 ft. Option D is correct.

<h3>What is the  Pythagoras theorem?</h3>

Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle.

It indicates that the area of the hypotenuse square is equal to the sum of the areas of the squares on the other two sides.

The given data in the problem will be;

L is the length of ramp=  10 feet

x is the horizontal distance from the bottom of the ramp = 8 feet

h is the height from the ground to the top of the ramp=?

According to Pythagoras theorem,

\rm H^2=P^2+B^2 \\\\  \rm l^2=h^2+X^2 \\\\ \rm 10^2=h^2+8^2 \\\\ \rm h=\sqrt{100-64 }  \\\\ \rm h=36 \\\\  \rm h=6 ft

Hence the height from the ground to the top of the ramp 6. 0 ft. Option D is correct.
