About 400 zebras live at the game reserve.
The proportion would be
30/150 = 80/x
This is because 30 zebras are tagged out of 150 in one area. We know that they tagged 80 total zebras out of x total zebras.
To solve this, cross multiply:
x*30 = 150*80
30x = 12000
Divide both sides by 30:
30x/30 = 12000/30
x = 400
Answer:
The answer is 12 cartridges
Step-by-step explanation:
Answer:
x = 6.86
Number of video games Fletcher has = 12.58
Step-by-step explanation:
Let
Number of video games Griffin has = x
Number of video games Tommy has = 3x
Number of video games Fletcher has = 3x - 8
Total number of video games is > 40
Griffin + Tommy + Fletcher > 40
x + 3x + (3x - 8) > 40
4x + 3x - 8 > 40
7x > 40 + 8
7x > 48
x > 48 / 7
x > 6.86
Number of video games Fletcher has = 3x - 8
= 3(6.86) - 8
= 20.58 - 8
= 12.58
Answer:
29/35
Step-by-step explanation:
probability of choosing a boy or an A student = (boys + a students - a boys)/total -->
probability of choosing a boy or an A student = (17 + 20 - 8)/35 -->
probability of choosing a boy or an A student = 29/35
Answer:
The answer is option C
Step-by-step explanation:
sin C = opposite / hypotenuse
the opposite is 40
the Hypotenuse is 50
so
sin C = 40/50 = 4/5
Hope this helps you
