The smaller triangle has a ratio of 11 : 10.
The smaller triangle and the larger triangle should have the same ratio.
The total of the left side of the larger triangle is 132cm
The ratio of the larger triangle is:
132 : (5x + 10) + 10
132 = 5x + 20
If you multiply the 11 : 10 ratio by 12, you get:
132 : 120
Since you know the other side should equal 120, to find x you do:
5x + 20 = 120
5x = 100
x = 20
Answer:
Grapes
Step-by-step explanation:
The rate of change for the grapes was -12 grapes per minute.
To calculate the rate of change for the carrots, use the slope formula . In this case, m is the rate of change, time is x, and the carrots remaining is y.
The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.
Answer:
1. 260 years
2. 3/6 I think I'm not sure
3. 5:30
4. 50 kg (I think)
5. 5 ft ( 54 in. = 4.5 ft)
6. x = 4
7. 9
8. false
9. Perpendicular
10. 40
The answer is 74. The parenthesis is another way of telling you to multiply.
