Answer:
A) 5.50x + 10y ≤ 800
B) yes
C) no
D) 80 pull buoys and 35 kick boards
Step-by-step explanation:
A) The sum of costs must not exceed the budget:
5.50x +10.00y ≤ 800
__
B) 5.50(0) +10.00(50) = 500 ≤ 800 . . . . . yes, the coach could buy these
__
C) 5.50(125) +10.00(25) = 937.50 > 800 . . . no, they cost too much
__
D) The point (80, 35) is in the solution space. The coach could buy 80 pull buoys and 35 kick boards.
The population in Cuba is expected to grow at a rate of 4% each year . Now is
<span>1.3million .
</span>This means that after 1 year the population in Cuba would be: 1.3 million+ 4%*1.3million=1.300.000+52.000=1.352.000
After the second year the population would be: 1.352.000 + 4% of 1.352.000=...
<span>After n years the population would be: population in the n-1 th year + 4% (population in the year n-1)
</span>In 10 years the population in Cuba would be: population in the 9-th year +4% from the population in the 9-th year
Answer:
11
Step-by-step explanation:
Given:
3/2y - 3 + 5/3z
When
y=6
z=3
3/2y - 3 + 5/3z
Substitute the value of y and z
3/2(6) - 3 + 5/3(3)
=18/2 - 3 + 15/3
=9-3+5
=6+5
=11
That would be 11:250
Hope this helps! (:
