Answer:

50ft

Step-by-step explanation:

Hi,

Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.

One of the legs is equal to 40 feet

So, tan(b) = 40/x

tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)

0.8 = 40/x

0.8x = 40

x = 50ft

A truck can be rented from Company A for ​$90 a day plus ​$0.50 per mile. Company B charges ​$40 a day plus ​$0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

Tthe number of miles in a day at which the rental costs for Company A and Company B are the same is    500 miles

The truck is driven X miles per day

Charges of company A will be = 90+0.5x

Charges of company B will be =40+0.60x

We need to find the value of X when charges of both companies are same

90+0.5X= 40+0.60x

   90-40 = 0.60x-0,50x

            50 = 0.10x

                    50/0.10= X

                             X= 500

The charges of both companies will be same if truck is driven 500 miles per day

How many seconds will it take to fill up an Olympic pool with Victoria Falls?

Answers

The volume of water pouring from Victoria Falls is enough to fill an Olympic swimming pool in around 2.03 seconds.

What is volume?

Volume, measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m³), a derived unit, is the SI unit of volume. Volume is another word for capacity.

To find out how many seconds it will take to fill up an Olympic swimming pool with the amount of water falling from Victoria Falls, we need to divide the total amount of water in the pool by the amount of water falling per second:

660,000 gallons ÷ 325,000 gallons/second ≈ 2.03 seconds

Therefore, it would take approximately 2.03 seconds to fill up an Olympic swimming pool with the amount of water falling from Victoria Falls.
