The exact value of tan(π4) tan ( π 4 ) is 1 .
Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm

I don’t believe there is any work to show for this question
Answer:
NO IF 14 POUND BURGERS
NO IF 1/4 POUND BURGERS
Step-by-step explanation:
2 3/8 POUNDS < 10
10- 2 3/8 = 7 5/8 REQUIRED TO MAKE 10 1 POUND BURGERS
If 1/4 pound burgers then you can just divide 1/4 into 2 3/8
= 2 3/8 / 1/4 = 9.5 BURGERS = No
Because 10-9.5 = 0.5 burger required
1/2 burger is not equivalent to 1 whole burger.
Answer:
22. 18
23. 10
Step-by-step explanation:
22
- you plug the number for the variable into the equation (3(2)²+6
- order of operations say exponents first so you do 2²=4 so you have 3(4)+6
- then you multiple 3•4=12 so 12+6
- finally you add 12+6=18
23
- plug in the number for the variable so 5–(-5)
- so a negative and a minus will make it addition (negative + negative = positive)
- do it is 5+5 which equals 10
