Answer:
(5/11)(1/10)
Step-by-step explanation:
probability of picking blue = 5/11
Now there are only 10 pencils
probability of picking yellow = 1/10
probability of picking blue, then yellow = (5/11)(1/10) = 1/22
Answer:
55
Step-by-step explanation:
there are two ways to answer : since angle 1 and the 125 degree angle are a linear pair, you can do 180-125 = 55, or, since the three angles in the triangle always add up to 180, you can do 180-37-88 = 55.
Answer:
12
Step-by-step explanation:
This is assuming that x2 means x to the power of 2 and that the x on the left is to represent multiplying. First, plug in all of the number to get 2*3+3^2-3.Using PEMDAS, you should solve the exponent to get 9. Then, multiply 2 by 3 to get 6. Add 6 to 9 to get 15. Subtract 2 to 15 to get 12.
TL;DR
2*3+3^2-3
6+9-3
15-3
12
Use FOIL (first, outer, inner, last) :
(<span>5h-3)(3h+7)
</span>(5h)(3h)+7(5h)-3(3h)-3(7)
15h^2+35h-9h-21
D: 15h^2+26h-21
Hope this helps :)
Answer:
80
Step-by-step explanation:
For these types of counting problems, just multiply all of the levels.
For example, this would be
4 choices
5 choices
4 choices
Multiply 4*5*4, and you get 80.
