Answer:
a
Step-by-step explanation:
the horizontal distance is shorter so the angle will be greater.
added:
tan a = AD/2a
tan Q - AD/3a
Just looking at the fractions AD/2a and AD/3a, the denominator of AD/2a is smaller so the resulting calculation will be greater, hence a is the larger angle.

$6.50 a dozen for $12 is the price per bagel proportion 2 the number of bagels brought.
Answers
Answer:
no
Step-by-step explanation:
1 bagel $1.50 ---------> unit cost: $1.50/bagel
2 bagels $2.25
6 bagels $6.50
12 bagels $12 ---------> unit cost: $1/bagel
Since the unit costs are not equal, the prices are not proportional.

Explanation: the phone originally costs $24 and is on a discount of 10%. this means that the price after the discount will be 90% of the original price, since the discount is 10% OFF.
to find 90% of 24, multiply 24 by .90, which is the decimal value of 90%.
24 x .90 = $21.60

The approximate 95% confidence interval for Swapna's page views is [341, 375].
What is confidence interval?It is a range of values that's likely to include a population value with a certain degree of confidence. It is expressed as a percent (%) where a population mean lies between an upper and lower interval.A confidence interval is how much uncertainty is with any particular statistic.When it is a 95% confidence interval, it means a range of values that you can be 95% certain contains the true mean of the population.A confidence interval is obtained from the observed data that holds the actual value of the unknown parameter.Formula of confidence interval:Confidence interval = mean ± Z * (standard deviation/ √sample size)
For given question,
Sample size = 40
Sample mean = 358
Standard deviation = 54.3
Critical value at 95% confidence level= 1.96
Confidence interval = 358 ± 1.96 * (54.3/ √40)
= [358 - 1.96 * (54.3/ √40) ,358 + 1.96 * (54.3/ √40)]
= [341, 375] (approximately)

The population of China was about 1.39 billion in the year 2013with an annual growth rate of about 0.6\% . Find an equation P(t) that represents the growth function for China. Write your answer in the form a * (b) ^ 2 in billions Provide your answer below:
Answers
Answer: 1.39(1.006)^t
Step-by-step explanation:
The equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.
What is a Function ?A statement that relates two unknown parameters such that one is dependent on the other is called a function.
It is given that
Initial population = 1.39 billion in 2013
Growth Rate = 0.6%
Let a represent the initial population
b is the growth rate
and 2 be the elapsed year from 2013
and let the population at any given year is P(t)
Then the equation formed is
P(t) = a * bⁿ
P(t) = 1.39 * ( 1.006)ⁿ
Therefore the equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.

Line m passes through the point (1, 2) and has a slope of 2/5 What is the equation of line m in standard form?
Answers
Answer:
5y - 2x = 8
Step-by-step explanation:
First off we have to find the y-intercept with : b = y-mx
[tex]b=2-(\frac{2}{5})(1)[/tex]
[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]
[tex]b=\frac{8}{5}[/tex]
now we have the point slope form
[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]
Multiply both sides by 5
[tex]5y=2x+8[/tex]
Subtract 2x from both sides
[tex]5y-2x=8[/tex]

Answer:
113.1 cm²
Step-by-step explanation:
we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius
so first, we need to find the radius
the length of the radius is half the length of the diameter
so that means that r=d/2
r=d/2
r=12/2
r=6
therefore the length of the radius is 6
now square 6, which is the same as multiplying it by itself
6²=36
now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7
so if we were to do 22/7 for instance,
36*22/7≈113.14
round that to 113.1
there's your answer :)

What fraction of the coin remains after 6 days?
What fraction of the coin remains after 28 days? Write an expression to describe this without computing its value.
Does the coin disappear completely? If so, after how many days?
Answers
Answer:
After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.
Step-by-step explanation:
Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:
1/2 ^ 6 = X
0.015625 = X
1/64 = X
1/2 ^ 28 = X
0.0000000037252902984619140625 = X
1/268435456 = X
Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

Answers
Answer:
Step-by-step explanation:
This doesn't factor. Not only that, but it does not give real results. The discriminate is negative.
a = 2
b = 4
c = 10
You could divide this equation by 2
a = 1
b = 2
c = 5
These three are smaller and easier to calculate. The answer will be the same.
x = (- b +/- sqrt(b^2 - 4*a*c ) / (2 a)
x = (-2 +/- sqrt(^2 - 4(1)*(5) ) / 2*1
x = (-2 +/- sqrt(4 - 20) ) / 2
X = (-2 +/- sqrt(-16) ) /2
x = (-2 +/- 4i ) / 2
x = ( - 1) +/- 2i

Ellie and three of her friends each bought two hamburgers and a drink at the soccer game. If the drink cost $1.25 and the total cost for all four girls was $18.20, what was the cost of a hamburger?
Answers
explanation: you have to multiply 1.25 with 4 for the drink which is 5 dollars they spent. subtract the total amount( 18.20) with the 5 dollars giving you 13.2. divide 13.2 with how many burgers they got. it says they each bought two so 4 times 2. so they got 8 burgers together. ( 13.2\ 8 = 1.65)
