Hello!
As the homework and test are two separate things, selecting an odd or even number on either of them will not affect the probability of selecting an odd or even number on the other.
Therefore, this pair of events is independent.
I hope this helps!
Alright. If we're multiply 3x by 3x, we can think of this as :
3 × x × 3 × x (since 3x is really just 3 × x)
We see that since it's all being multiplied together, it doesn't matter what order we do. 3 times 3 is 9, so we now have
9 × x × x
When multiplying the same type of variables, we add their exponents. if an exponent isn't shown, it's understood that there's an invisible 1 there. So we really have x^1+1 once we multiply x×x. So really, x × x is x^2. so, I now have:
9 × x^2 or 9x^2
I see that this isn't an available solution. Please recheck your answers, or what the original problem was. I can assure you that with the info provided, 9x^2 is undoubtedly the answer. Perhaps you meant 3x + 3x?
For the second problem, we just have to see how many times we need to add 5 to itself until we get 20. How many times we have to add is how many months he has to save.
5 + 5 + 5 + 5 = 20
So, 4 times, means he has to save for 4 months.
Hope this helps, and please let me know what happened with question 1!
Answer:
<u>En español:</u>
A. Rotación de tres cuartos en sentido antihorario.
3/4 = 270 grados
B. Cinco sextos de rotación en sentido antihorario.
5/6 = 300 grados
C. Diez octavos de rotación en el sentido de las agujas del reloj.
10/8 = 450 grados
D. Un quinto de rotación en el sentido de las agujas del reloj
1/5 = 72 grados
<u>In English:</u>
a. Three-quarter rotation counterclockwise.
3/4 = 270 degrees
b. Five sixths of rotation counterclockwise.
5/6 = 300 degrees
c. Ten-eighths of a clockwise rotation.
10/8 = 450 degrees
d. One-fifth clockwise rotation
1/5 = 72 degrees
Answer:
36.46 inches
Step-by-step explanation:
The tangent of the angle is the ratio of the height to the base length:
Tan = Opposite/Adjacent
tan(25°) = (17 in)/(base)
base = (17 in)/tan(25°) ≈ 36.46 in
The base of the ramp is about 36.46 inches long.
Answer:
Area of triangle: 18
Area of semicircle: (9pi)/2
perimeter of triangle: 20.49
perimeter of semicircle: 3pi+6
perimeter of whole thing: 23.91/ 6+8.49+3pi
Step-by-step explanation:
triangle area: 1/2bh, 1/2*6*6=18
Area of circle: pir^2, 3^2*pi, 9pi, semicircle means half, 9pi/2
