Answer:
14.17m
Step-by-step explanation:
1 / 1.2 = x / 17
x = 17 / 1.2 = 14.1666667 -> 14.17m
14.17m tall is the building (to 2 decimal places).
What is after the decimal point?Digits after the decimal point. The position of the digit to the right of the decimal point of the number is written in decimal notation. For example, 0.079 has 0 decimal places, 7 decimal places, and 9 decimal places.
Rounding a decimal number to two decimal places is the same as rounding to one-hundredth of the second decimal place. For example, 2.83620364 can be rounded from 2.84 to two decimal places, and 0.7035 can be rounded from 0.70 to two decimal places.
1 / 1.2 = x / 17
x = 17 / 1.2 = 14.1666667 -> 14.17m

The fish population of Lake Collins is decreasing at a rate of 5% per year. In 2001 there were about 1,200 fish. Write an exponential decay function to model this situation. Then find the population in 2006.
The student's question involves creating an exponential decay function to determine the fish population in Lake Collins after five years, given a starting population in 2001 and a 5% annual decrease. The function is N(t) = 1200e^-rt, with r being 0.05 and t being 5. The estimated fish population for the year 2006 is approximately 935.
The student is asking for an exponential decay function to model the decrease in the fish population at Lake Collins. We are given that in 2001, there were about 1,200 fish, and the fish population is decreasing at a rate of 5% per year. To model this situation, we use the exponential decay formula:
N(t) = N0e-rt
Where:
N(t) is the fish population at time tN0 is the initial fish populationr is the decay rate (as a decimal)t is the time in years since the initial countFor this problem, the initial population N0 is 1,200, the decay rate r is 0.05 (since 5% is 0.05 as a decimal), and the time t we are interested in is 2006 - 2001 = 5 years. Plugging these values into the formula, we get:
N(5) = 1200e-0.05 * 5
Calculating N(5), the fish population in 2006, using the above formula:
N(5) = 1200e-0.25 ≈ 1200 * 0.7788 ≈ 935
Therefore, the estimated fish population in Lake Collins in 2006 would be approximately 935 fish.
Steve decided to buy a box of pizza from another restaurant. The
restaurant is offering a square pizza and a round pizza. Round pizza
has an area of 49 pi square inches. The square pizza has an area of 49
square inches. Which box of pizza will Steve buy if he wants to eat
more crust? Explain your reasoning.
Show your work
Answer:
Round pizza
Step-by-step explanation:
Area of the Round Pizza =[tex]49 \pi[/tex] square inches.
Area of the Square Pizza = 49 square inches.
Recall that: [tex]\pi =\frac{22}{7}[/tex]
Therefore:
Area of the Round Pizza =[tex]49 \pi=49X\frac{22}{7}=154 \:Square \:Inches[/tex]
Since 154 is greater than 49(154>49)
If Steve wants to eat more crust, he will buy the round pizza.

April rewrote a quadratic function in vertex form.
h(x) = 5x2 – 30x + 30
Step 1: h(x) = 5(x2 - 6x+ + 30
Step 2: h(x) = 5(x2 - 6x + 9) + 30 – 45
Step 3: h(x) = 5(x - 3)2 + 15.
April said that the vertex is (3, 15). Is April correct?
April correctly transformed the quadratic function into vertex form, and the resulting vertex is (3, 15), as determined by the completion of the square method.
Explanation:April is indeed correct about the vertex of the function h(x). The vertex form of a quadratic function is h(x) = a(x - h)^2 + k, where the point (h, k) is the vertex of the parabola. April has rewritten the quadratic function h(x) = 5x^2 - 30x + 30 into vertex form as h(x) = 5(x - 3)^2 + 15, indicating that the vertex is at (3, 15). This can be verified through the completion of the square method, where a perfect square trinomial is created by adding and subtracting the appropriate constant term. April added and subtracted 9 inside the parentheses, which is (6/2)^2, to keep the equation equivalent. Finally, she factored out the coefficient of the quadratic term (5) before completing the square, which is correct.

The Venn diagram represents probabilities associated with two events. A is the event that the student has a regular afterschool activity, and B is the event that the student comes to school by bus. What is the probability that the student has an after-school activity and does NOT come to school by bus?
Answer:
0.22
Step-by-step explanation:
Looking at the Venn Diagram,
the intersection "0.43" means coming via bus and having after-school activity.
"0.12" means students who does not come by bus and who does not have after-school activity.
Now, we want probability of "having after-school" activity (the area A) but NOT COMING VIA BUS (area outside B).
We want the area outside B but within A.
That area is labeled 0.22
Hence,
The probability that the student has an after-school activity and does NOT come to school by bus is 0.22

How can you record hundredths as fractions and decimals?
Hundredths as fractions and decimals is given below.
Step-by-step explanation:
When we write a decimal number, look at the decimal point first. If the last number is two places away from the decimal point, it is in the hundredths place. The number 0.39 would be written as thirty-nine hundredths. The nine is the last number and is in the hundredths place.First, convert the decimal to fraction using tenths, hundredths, thousandths, etc. depending on the number of decimal places. e.g. 1.75 = 1 75/100. Next, simplify the fraction part to the lowest common term. e.g. 75/100 = 3/4.5 hundredths is 5 over one hundred, 5 hundredths as a Fraction is 5/100. If you divide 5 by one hundred you get 5 hundredths as a decimal which is 0.05.To convert a fraction to decimal, we divide the numerator by the denominator using long division and to convert a fraction to percent, we convert the fraction to decimal and the decimal to percent. To convert a percent to decimal or fraction, we divide the percent by 100 and reduce the fraction.4 hundredths is 4 over one hundred, 4 hundredths as a Fraction is 4/100. If you divide 4 by one hundred you get 4 hundredths as a decimal which is 0.04.To learn more about this :

Alice has two flying disks. One is 12 cm in diameter and the other is 24 cm in diameter. What is the difference between the areas of the two flying disks?
Answer:
432π cm² or 1356.48 cm²
Step-by-step explanation:
The area of a circle is πr²
The area of the disks are 144π and 576π.
576π-144π = 432π
432π ≈ 1356.48 cm²
To find the difference in areas of two circles, calculate the area of each circle using the formula πr² and then subtract the smaller area from the larger one. For Alice's discs with diameters 12 cm and 24 cm, the areas are 36π and 144π square cm respectively, and their difference is 108π square cm.
Explanation:To find the difference in the areas of Alice's two flying disks, first we need to calculate the area of each disk. The formula for the area of a circle (or disk) is πr², where r is the radius of the circle. The radius is half of the diameter, so for the first disk, the radius is 6 cm and for the second disk, the radius is 12 cm.
The area of the first disk is π*(6 cm)² = 36π square cm. The area of the second disk is π*(12 cm)² = 144π square cm. The difference between these two areas is 144π - 36π = 108π square cm.

Margo deposited $100 into a savings account earning 4.5% simple annual interest. At the end of each year, she adds $100 to her account. Fill in the table below to figure out how much money was in Margo's account at the end of 3 years.
Answer:
principal interest total money in account
at the end of year
Year one $100 $4.5 $104.5
year two $200 $ 9 +$4.5 $ 213.5
year three $300 $ 9 +$4.5 + $13.5 $ 327
Step-by-step explanation:
Simple interest for any principal is given by
I = p* r* t/100
I = interest rate accrued on principle amount
p is the amount deposited
r is the rate of interest
t is the time period of saving
_______________________________________________
For year one
p = $100
r = 4.5%
t=1
I = 100*4.5*1/100 = 4.5
_______________________________________________
For year two $100 more is added to already existing $100 in account.
p = 100 +100 = $200
r = 4.5%
t=1
I = 200*4.5*1/100 = 9
_______________________________________________
For year two $100 more is added to already existing $200 in account after two years.
p = 100 +100 +100 = $300
r = 4.5%
t=1
I = 300*4.5*1/100 = 13.5
_______________________________________________
There fore total money in Margo account is
$300 saving deposited by her
$4.5 + $9 + $13.5 = $27 (interest accrued in three time)
Formulating the results in tabular form
principal interest total money in account
at the end of year
Year one 100 4.5 104.5
year two 200 9 +4.5 213.5
year three 300 9 +4.5 + 13.5 327

Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink.
Using these equations, determine and state the price of a drink, to the nearest cent.
Answer and Step-by-step explanation:
samuel---> 1pc+3dr=36.75
sebastian--->3pc+12dr=138
1pc+4dr=46
1pc+4dr=46
1pc+3dr=36.75
so 1 dr=46-36.75=$9.25
4dr is 9.25×4=37
so 1 pc=46-37=$9.00
Answer:
$9.25
Step-by-step explanation:
Cost of popcorn: x
Cost of drink: y
x + 3y = 36.75
x = 36.75 - 3y
3x + 12y = 138
x + 4y = 46
36.75 - 3y + 4y = 46
y = 46 - 36.75
y = 9.25
