s < 30,000$ i dont know if this is what the question is asking but its the best i can come up with given the information you gave to me.
Bicycle has 2 wheels and 2 pedals
tricycle has 3 wheels and 2 pedals
EQ 1 : 2b + 2t = 170 pedals
EQ 2: 2b +3t = 206 wheels
subtract EQ 1 from EQ 2
2b +3t = 206 - 2b + 2t = 170 = t=36
there were 36 tricycles
36 x 2 = 72 pedals
170 pedals - 72 = 98 pedals left
98/2 = 49 bicycles
36 Tricycles and 49 bicycles
1.5 cups of flower, 3 cups sugar, 3 tbsp. baking powder, 1.5 eggs, 1.5 cups of Crisco, 1.5 cups of skim milk (hopefully not skin milk), and 1.5 cups of blueberries. Because 18 is 12 x 1.5 you just multiply all the given numbers by 1.5.
Answer:
2/27
Step-by-step explanation:
This is a probability question and we are asked to estimate a particular probability. We proceed as follows:
The total number of sweets is given as 8 + 9+ 11= 28 sweets
He takes out a sweet to eat, the probability of this being a red sweet would be P(r1) = 8/28 = 2/7
Now he takes another sweet, we are asked to calculate the probability that this sweet is also red. Now after taking the first sweet, the number of sweets is now 27, while the number of red sweets is now 7. Hence the probability of having a red sweet taken in the second case would be p(r2) = 7/27
Now, the probability of both being red sweets can be calculated by multiplying both = 7/27 * 2/7 = 2/27
