Answer: 2730 tiles (Approx)
Step-by-step explanation:
Since, The side length of each side = 25
According to the question the shape of the tile is square.
Thus, the area of one tile = 25 × 25 = 625 
Also, we need to tile a kitchen measuring 102 ft. by 18 ft
Thus, the area of the room in which we have to tile = 102 × 18 = 1836 
= 1836×30.48 × 30.48 = 1705699.8144
Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile = 
Since, we must take 2730 tiles to tile the kitchen.
Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
By this equation y = 1,716 - 112x he find that how much money he still owes after each month of the plan.
According to the statement
Jonathan bought a new computer for $1,716
He will pay $143 a month for 12 months.
Total amount he will for 12 months is 143(`12)
Now,
y = the money he still owes
x = the number of months (from x = 0 to x = 12)
y = 1,716 - 112x
So, By this equation y = 1,716 - 112x he find that how much money he still owes after each month of the plan.

Answer:
(x-1) (x+4)
Step-by-step explanation:
Factor x^2+3x-4 using the AC method
We need to find the value of the hypotenuse in order to solve this problem.
12^2+4^2=H^2
Therefore:
H=√(144+16)
H=4√10
Now:
sin(G)=O/H=4/(4√10)
=1/(√10)
=(√10)/10
