Question 17: There were 900 students initially infected by the flu. After
medicine was distributed, the number of sick students was cut in half
every week. How many will still be sick after 4 weeks?
Answers
Answer:
56 will be sick after 4 weeks.
Step-by-step explanation:
900 / 2 = 450 (Week 1)
450 / 2 = 225 (Week 2)
225 / 2 = 112.5 (Week 3)
112.5 / 2 = 56.25 (Week 4)
(Rounding to a whole number since there can't be a quarter of a child)
Answer:
56.25 students would still be sick after 4 weeks

The roof of the building shown below has a span of 48 feet. The rafters upon which the roof is laid are 30 feet long, including a 4 foot overhung. a. Knowing that the pitch of a roof is the ratio of the rise to the run, find the pitch of this roof. B. If the entire roofline measures 100 feet from end to end, find the total area of the roof. c. Find the percent of the roof used for the overhang
Answers
Solution :
Given :
Span of the roof = 48 feet
Length of the rafter = 30 feet (including the 4 feet overhung)
So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.
Therefore, the horizontal span per rafter is
[tex]$=\frac{48}{2}$[/tex]
= 24 feet
a). So the rise of the roof is [tex]$= \sqrt{(26)^2-(24)^2}$[/tex]
= 10 feet
b). Pinch of the roof is [tex]$=\frac{\text{rise}}{\text{run}}$[/tex]
[tex]$=\frac{10}{24}$[/tex]
[tex]$=\frac{5}{12}$[/tex]
c). The percent of the roof used as overhung is
[tex]$=\frac{4+4}{60}\times 100$[/tex]
[tex]$=\frac{80}{6}$[/tex]
= 13.33 %

Gary's parents want him to attend The University of Houston. They opened a college savings account 15 years ago. Today, average yearly tuition and fees for one year at the university are about $10,350. Based on this information, about how much should Gary's parents have saved each of the 15 years to cover the cost of 4 years at The University of Houston?
Answers
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Today, average yearly tuition and fees for one year at the university are about $10,350.
I will assume a yearly interest rate of 8%.
First, we need to calculate the total amount needed:
Future value (FV)= 10,350*4= $41,400
Now, using the following formula, the annual deposit required:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (41,400*0.08) / [(1.08^15) - 1]
A= $7,194.22
