Step by step, we have:
1 • （-1）= -1
Then -1 • 1 = -1 and -1 • （-1）= 1 =》 1 - 1 = 0
The answers is 0
Answer:
1 = 52
2 = 68
3 = 40
4 = 25
Step-by-step explanation:
1 = (4 + 3)^2 + (12 / 4)
7^2 + 3
49 + 3
= 52
2 = (12 x 9 - 7^2) + 9
(108 - 49) + 9
59 + 9
= 68
3 = (30 - 2) / 7 + 6^2
28 / 7 + 36
4 + 36
= 40
4 = (2 x 7 + 4^2) - 5
(14 + 16) - 5
30 - 5
= 25

Answer: There is an important difference between the way counts are viewed in ratio to that in fractions. The ratio of boys : girls →4:5 so you have 4 boys and 5 girls making the whole count 4+5=9 in its simplest form. ... girls →59 of the whole.
Step-by-step explanation: have a good day!
sin(P) = side opposite angle p / hypotenuse = 5 / 13
tan(T) = side opposite angle T / side besides angle T = 12 / 5
cos(T) = side beside angle T / hypotenuse = 5 / 13
Hope that helps!
The given triangle is a right-angled triangle. This means that special trig identities can be applies
<u>These identities are as follows:</u>
sin (theta) = opposite / hypotenuse
cos (theta) = adjacent / hypotenuse
tan (theta) = opposite / adjacent
<u>Now, for the unknown theta in the triangle:</u>
The opposite side is 16 and the hypotenuse is 20
This means that we will use the <u>sin</u> not the cos as Bob did
<u>The solution will be as follows:</u>
sin (theta) = opposite / hypotenuse
sin (theta) = 16 / 20
theta = sin^-1(16/20)
theta = 53.13°
Hope this helps :)
