The interior of a triangle = 180°
So 180° - 85° -50° = 45°
c. 45 degrees
so as you can see the common ratio is 2, and the first term is 1/2,
16) 9y+2r If she bought 1 dog toy and 2 treats: 9(1)+2(2)= 13
17) 5n-3n= 2n
17-2+7= 22 Combine like terms
2n+22 Write out expression
2(8)+22= 38 Plug in 8.
Answer: 2n+22; 38
18) 5h^3 h represents the # of weeks; Find # of tickets sold in 3 weeks:h=3
5(3)^3 plug in 3
5(27) PEMDAS; Exponents first; 3*3*3= 27
Answer: 135
19) It is true
If d=2, 5(2)*5(2)*5(2)= (5*2)^3
10*10*10=(10)^3
1,000=1,000
Answer:
I agree with both of them
Step-by-step explanation:
A dozen is 12 muffins. Therefore, you pay $3.00 for 12 muffins.
We know that you pay $3.00 for 12 muffins we need to find out how much EACH muffin cost. For that we need to divide $3.00 by 12 which is 0.25.
Now we need to know how much it will cost us for 16 muffins. We use our equation 16*0.25 which is 4. Elena said she will pay 4 so she is right.
Andre said he will buy 8 muffins so we use our equation again 8*0.25 which is 2. He said he will pay 2 so he is right.
Step-by-step explanation:
since both spinners are independent from each other, we can directly multiply their probabilities for the combined event.
1)
1/5 × 1/3 = 1/15
2)
1/5 × 2/3 = 2/15
3)
2/5 × 1/3 = 2/15 (you got that wrong on your paper)
4)
2/5 × 2/3 = 4/15
5)
3/5 × 1/3 = 3/15 = 1/5
6)
3/5 × 2/3 = 6/15 = 2/5
