45 × 2 (because half) = ?/90 minutes.
Answer:
Dawn has 32 pens.
Step-by-step explanation:
- Let No. of pens Alice has = A
- Let No. of pens Maurice has = M
- Let no of pens Paul has = P
- Let no. of pens Suzy has = S
- Let no of pens Dawn has = D
Given :
- A = 7M
- P = 2/3 (A + S)
- D = P + 12
- S = 1/2 M
- If S = 2 {Given}
- M = 4 [∵ S = 1/2 M → M = 2S = 2X(2) ]
- A = 28 [ ∵ A = 7M → A = 7 x 4 ]
- P = 20 [∵ P = 2/3 (A+S) → P = 2/3 (28 + 2) = 2/3 (30) ]
- D = 32 [ ∵ D = P + 12 → D = 20 + 12 ]
Answer: 500 front row tickets and 400 back row tickets were sold.
Step-by-step explanation:
Let x represent the number of front row tickets that were sold.
Let y represent the number of back row tickets that were sold.
A traveling puppet show sold 900 tickets for a certain performance. It means that
x + y = 900
If front row tickets sold $3 each and back row tickets for $2 each, and if the total sales were $2300, it means that
3x + 2y = 2300 - - - - - - - - - 1
Substituting x = 900 - y into equation 1, it becomes
3(900 - y) + 2y = 2300
2700 - 3y + 2y = 2300
- 3y + 2y = 2300 - 2700
- y = - 400
y = 400
Substituting y = 400 into x = 900 - y, it becomes
x = 900 - 400
x = 500
Answer:
48%
Step-by-step explanation:
96 out of the 200 species of birds have been seen nesting. To make it easier, let's make it out of a hundred. Just divide both numbers by 2, this will result in the ratio being 48 out of 100. Now, we have our percentage, 48%.
