The answer is 168 logs.

1st row:          15 logs
2nd row:        18 logs
3rd row:         21 logs
(so, each row has 3 more logs)
4th row:         24 logs
5th row:         27 logs
6th row:         30 logs
7th row:         33 logs

The sum of logs from each row is: 15 + 18 + 21 + 24 + 27 + 30 + 33 = 168 logs

Find 2/3 of 18. Draw a set and shade to show your thinking.
ioda

Answer:

\text{2/3 of 18}=12

Step-by-step explanation:

We are asked to find 2/3 of 18.

To find 2/3 of 18, we will multiply both quantities as:

\text{2/3 of 18}=\frac{2}{3}\times 18

\text{2/3 of 18}=2\times 6

\text{2/3 of 18}=12

Therefore, 2/3 of 18 is equal to 12.

City A is 25% less than population of city B so city A's population is what % of city B
Lerok [7]

City A is 25% less than population of city B. So city A's population is 75% of city B

<h3><u>Solution:</u></h3>

Given that City A is 25% less than population of city B

To find: city A's population is what % of city B

From given information,

City A is 25% less than population of city B

A = B - 25% of B

So we can write as,

A = B - \frac{25}{100} \times B\\\\A = B - 0.25B\\\\A = 0.75B

A = 0.75B can be written as,

A = \frac{75}{100}\times B

city A = 75 % of City B

Thus city A's population is 75% of city B

A town has a fireworks display, where fireworks are set off from a bridge over a lake. The function h (t) = -16t2 + 150t + 10.5
Elodia [21]

Answer:

h(t) = 4.68 seconds

Step-by-step explanation:

The function that represents the height of each firework in feet is :

h (t) = -16t^2 + 150t + 10.5 .....(1)

We need to find the time the fireworks take to reach their maximum height. For maximum height,

dh/dt = 0

So,

\dfrac{d}{dt}(-16t^2 + 150t + 10.5 )=0\\\\-32t+150=0\\\\t=\dfrac{150}{32}\\\\t=4.68\ s

Put t = 4.68 in equation (1).

h (t) = -16(4.68)^2 + 150(4.68)+ 10.5\\\\h(t)=362.06\ text{feet}

So, the fireworks will take 4.68 seconds to their maximum height.
