Answer:
3) 8
4) 5.25 cups
Step-by-step explanation:
3) cross multiply:
36 × 10 = 360
45 × x = 45x
equate them both:
360 = 45x
divide both sides by 45
360 ÷ 45 = 8
x = 8
4) 8 people : 3 cups of flour
14 people : how many cups?
14 ÷ 8 = 1.75
to get from 8 people to 14 people we multiply by 1.75, so do the same thing to the 3 cups:
3 × 1.75 = 5.25 cups
They would have 4 slices each.
12 slices/ 3 people= 4 slices
X= 75
y= 105
this is because x is equal to the angle with 75, y us 105 because 180-75=105. 180 is found because the angle of a line is 180
Answer:the number of marbles in the bag that are not blue is 44
Step-by-step explanation:
The probability of picking a blue marble out of a bag of 50 marbles is 3/25. This means that the number of blue marbles in the bag would be
3/25 × 50 = 150/25 = 6
Since the total number of marbles in the bag is 50, it means that the number of marbles in the bag that are not blue would be
50 - 6 = 44 marbles
