If a represent the ages of the children that are to pay for the ticket. a should be greater than or equal to 6 and it should also be lesser than or equal to 12. Thus, the inequality that best represents the ages of the children is,
6 ≤ a ≤12
The number of plastics of the size of 13 ft x 10ft will be 4.
<h3>What is the area?</h3>
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that:-
- A tennis match was delayed because of the rain. The officials were not prepared for the delay.
- They covered the 25ft by 20ft court with 13ft by 10ft plastic covers.
The number of the plastic required will be calculated as:-
When the total area of the tennis court will be divided by the area of the one plastic we will get the number of the plastic required.
Area of court = 25 x 20 = 500 square feet
Area of plastic = 13 x 10 = 130 square feet.
Number of the plastic = Area of court ÷ Area of plastic
= 500 ÷ 130
= 3.89 ≅ 4 plastics
Therefore the number of plastics of the size of 13 ft x 10ft will be 4.

Answer:
68.6 Trips
Step-by-step explanation:
2.5m+1.5m+1.0=5
5m per trip
7m^3=343
divide the amount that can fit in each trip (5m)
by the amount of sand needed for the sculpture. (343m)
343 /5=68.6
Answer:
-2 1/2
Step-by-step explanation:
The first thing to do here is turn 8 3/4 and -3 1/2 into fractions(we will convert to mixed number at the end). So you get: 35/4 and -7/2.
That gives you (35/4)/(-7/2).
Then you use keep change flip to simplify this.
(35/4) * -2/7 = 2.5
2.5 as a mixed number is:
-2 1/2
Answer:
-0.462
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the population mean(the null hypothesis), is s is the standard deviation of the sample.
In this problem:
So
So the correct answer is:
-0.462
