Cory has a poster in his room that has an area of 7 2/3 sq. inches and a length of 2/3 inches. how many inches is the width of the poster?

Answers

Answer 1

Answer: area=legnth times width
legnth=2/3
area=7 and 2/3
convert 7 and 2/3 to improper fraction for convenience
7 and 2/3=23/3
23/3=2/3 times width

multiply both sides by 3/2 to clear fraction
69/6=width
23/2=width
7 and 1/2=width

widht=7 and 1/2 in
(NOTE: normallly length is longer then width since legnth is the longer side, and the width is the other side)

Tom knows that in his school 10out of every 85 students are lefthanded. There are 391 students in Toms school. How many studentd in toms school are left handed

Answers

To do this, first divide 85 by 10

You get 8.5

Then, divide 391 by 8.5

You get 46

Therefore, 46 students are left-handed in Tom's school.

3. An airplane flies 105 miles in ½ hour. How far can it fly in 1 ¼ hours at the same rate of speed?

Answers

262.5 miles
explanation 1/4 is half of 1/2 so 52.5 is half of 105 and then 210 for an hour of travel

Answer:

105 at 30 min.

x at 75 min.

105 mph x 2 = 210 mph at one hour

There is still 15 min to go soooo...

210/4 = 52.5

210 + 52.5 = 262.5 mph for 75 min

Check by dividing

262.5/75=3.5

Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision

Answers

The best way to solve this problem is to use the 'rule of three":

If 15% correspond to 100%

then 18% correspond to X%

We notice that both lines are in the following proportion:

(15) / (100%) = (18) / (X%)======> X%= (18 x 100%) / 15= 6/5 = 1.2 =120%

Answer:

Maxine is incorrect.

Step-by-step explanation:

18 - 15 = 3 3/15 = 0.2 0.2(100) = 20.

20% is the percent of increase. 120% would be the total of both combined. Since we are only looking for how much more, it would be 20%.

Part B) Which of the following functions most appropriately models the data, where x represents the number of millions of dollars of revenue from Tallahassee theaters?

f(x) = -0.805x + 38.967
f(x) = 0.805x + 38.967
f(x) = -0.001x2 - 0.543x + 37.389
f(x) = 0.001x2 - 0.543x + 37.389

Answers

The correct answer for the data is (d) f(x) = 0.001x² - 0.543x + 37.389.

What is an expression?

To determine which function most appropriately models the data, we need to examine the characteristics of the data and compare them with the characteristics of the functions.

The data represents the revenue from Tallahassee theaters, which means that the revenue is likely to increase as the number of theaters and the number of people attending the theaters increases. Therefore, we can eliminate options (a) and (b) because they have negative coefficients on x, which would indicate a decreasing revenue as x increases.

Option (c) is a quadraticfunction, which allows for a more complex relationship between the revenueand the number of theaters. However, the coefficient on the x² term is very small (0.001), which suggests that the quadratic term has little effect on the revenue compared to the linear term. In addition, the constant term (37.389) is relatively low, which would imply a low revenue even when the number of theaters is zero.

Option (d) is also a quadratic function, but it has a larger coefficient on the x² term (0.001) and a higher constant term (37.389), which would result in a higher revenue even when the number of theaters is zero. Therefore, option (d) is the most appropriate function to model the data.

So, the correct answer is (d) f(x) = 0.001x² - 0.543x + 37.389.
