Answer:
(X,y)=(15/2,25/4) thanks for all the answers
Answer:
Area of floor = 21.6m2
area of tile = 576cm2=0.0576m2
now,
number of tiles = 21.6/0.0576
= 375
We have been given the function

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

Now, we simplify this step by step.
First of all
. Thus, we have

Now, we can easily simplify it by PEMDAS


Therefore, the value of f(3) is 98.
For 4 copies, the total cost for preparing and printing will be the same.
Step-by-step explanation:
Let,
p be the number of pages
Company A;
Charges of preparing = $6
Charges of per page print = $2.50
A(p)= 2.50p + 6 Eqn 1
Company B;
Charges of preparing = $4
Charges of per page print = $3
B(p)= 3p + 4 Eqn 2
For equaling the cost;
A(p) = B(p)

Dividing both sides by -0.50

For 4 copies, the total cost for preparing and printing will be the same.

Answer:
13.8
Step-by-step explanation:
tan Q = <u>opposite </u> = <u>40</u>
adjacent x
Tan 71 = <u>40</u> x tan 71 = 40
<u> x tan 71</u> = <u> 40 </u>
tan 71 tan 71
x = <u> 40 </u> = 13.7731 = 13.8 (rounded to the nearest tenth)
tan 71
