The measure of ∠ADC will be the sum of the measures of the two acute angles ADB and BDC.
__
Each acute angle with a measure that is a whole number of degrees will have a measure between 1° and 89°, inclusive.
The least sum of two such angles will be ...
1° +1° = 2°
The greatest sum of two such angles will be ...

Answer:
arc BC = 26°
arc AB = 90°
arc CAB = 334°
Step-by-step explanation:
The angles of a linear pair total 180°. This fact lets us write an equation for x that helps us find the measures of all the angles and arcs. The arcs of a circle total 360°.
__
equation∠APE +∠EPD = 180°
(25x +15)° +(33x -9)° = 180°
58x = 174 . . . . . . divide by °, subtract 6
x = 3 . . . . . . . . divide by 58
anglesAngle APE is ...
∠APE = (25x +15)° = (25·3 +15)° = 90°
Then ...
∠EPD = 180° -90° = 90°
∠DPC = (20·3 +4)° = 64°
∠CPB = 90° -64° = 26°
arcsarc BC = ∠BPC = 26°
arc AB = ∠APB = 180° -90° = 90°

find the missing angle,
thanks.
Given :
48°
90°{boxed like shape}
x + 48 + 90° = 180°{sum of angles of triangle}
x + 138° = 180°x = 42°~Tulpe⚘
Answer:
x = 42°
Step-by-step explanation:
Given that,
→ A = 48°
→ B = 90°
→ C = x
Formula we use,
→ A + B + C = 180°
Let's solve for the value of missing angle,
→ A + B + C = 180°
→ 48° + 90° + x = 180°
→ 138° + x = 180°
→ x = 180° - 138°
→ [ x = 42° ]
Hence, value of missing angle is 42°.
1. In 2012, the population of a city was 5.68 million. The exponential growth rate was 2.99% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be 10 million?
d) Find the doubling time.
Answer:
So first we need to determine what the exponential growth function would look like. Exponential growth functions look like [tex]P(t) = P_0*e^{r*t}[/tex] and in our case [tex]P_0[/tex] would be the initial population which is 5.68 million. R is the next variable that we need to fill out which is the rate of change which in our case is 2.99% or 0.0299.
This is how our function should look now [tex]P(t)=5.68*e^{0.0299*t}[/tex]
Moving onto part b, we need to estimate the population of the city in 2018 which 6 years from 2012 and we plug that into t and solve.
[tex]P(t)=5.68*e^{0.0299*6}[/tex]
[tex]P(t)=5.68*e^{0.1794}[/tex]
[tex]P(t) = 5.68*1.1965[/tex]
[tex]P(t) = 6.796\ million[/tex]
Moving onto part c, we need to find when the population of the city will be 11 million which will be done by setting P(t) to 10 million and solving for t.
[tex]10 = 5.68*e^{0.0299*t}[/tex]
[tex]\frac{10}{5.68} = \frac{5.68*e^{0.0299*t}}{5.68}[/tex]
[tex]1.76056=e^{0.0299*t}[/tex]
[tex]ln(1.76056)=ln(e^{0.0299*t})[/tex]
[tex]\frac{0.5656}{0.0299}=\frac{0.0299*t}{0.0299}[/tex]
[tex]18.9175\ years = t[/tex]
Moving onto part d, we need to find the doubling time. This will be similar to the previous part but we will be finding the time it takes to double our population. So instead of putting 10 million for P(t) we put 5.68* 2 in there which is 11.36.
[tex]11.36= 5.68*e^{0.0299*t}[/tex]
[tex]\frac{11.36}{5.68} = \frac{5.68*e^{0.0299*t}}{5.68}[/tex]
[tex]2=e^{0.0299*t}[/tex]
[tex]ln(2)=ln(e^{0.0299*t})[/tex]
[tex]\frac{0.693}{0.0299}=\frac{0.0299*t}{0.0299}[/tex]
[tex]23.182\ years = t[/tex]

From a candy machine a random handful of colored chocolate candies are dispensed with 2 quarters. In one turn the machine dispenses 3 blue candies, 5 red candies, and 4 yellow candies. If you hide them in your hand and drop them one at a time into the other hand to eat them, what is the probability that the first candy will be blue and the second candy will be yellow?
Answer:
the answer should be 1/11
Step-by-step explanation:
p(blue first) = 3/12
p(yellow second) = 4/11
so p = 3/12 x 4/11

She buys 2 bicycle reflectors for $18.41 each and a pair of bike gloves for $10.76.
She plans to spend some or all of the money she has left to buy new biking outfits for $66.40 each.
Write and solve an inequality which can be used to determine oo, the number of outfits Shandra can purchase while staying within her budget.
Answer:

Step-by-step explanation:
Total budget = 760
Money left = 760 - 433.54 - 2*18.41 - 10.76 = 278.88
278.88 > oo * 66.4
oo < 4.2

How would the mean change if the number 52 replaced the number 12 in the set?
10, 61, 10, 44, 21, 79, 27, 12
Question 1 options:
decrease
increase
no change
Answer:
increase
Step-by-step explanation:
First, we need to find the mean of the given data set without any change.
10 + 61 + 10 + 44 + 21 + 79 + 27 + 12 = 264
264 ÷ 8 = 33
Now that we have the mean, we can find the mean of the data set with the change of 52.
10 + 61 + 10 + 44 + 21 + 79 + 27 + 52 = 304
304 ÷ 8 = 38
From this, we can see that the mean has increased with the change of 12 to 52. Thus, that's the correct option.

Which of the following estimates at a 95% confidence level most likely comes
from a small sample?
A. 48% (+21%)
B. 53% (+3%)
C. 59% (+5%)
D. 67% (+7%)
Answer:
Option A
Step-by-step explanation:
95% confidence interval is obtained using the following formula
COnfidence interval lower bound = mean - critical value * sigma/sq rt n
and upper bound = mean + critical value*sigma/sq rt n
Thus margin of error = critical value*sigma/rt n
varies indirectly as n provided others are remaining the same.
Hence lower sample indicates higher margin of error
Out of 4 options given we find that I option has maximum margin of error as 21%
Hence option A is most likely coming from a small sample

The length of the straw will be 9.89949 inches long in radical form.
What is Length of diagonal in cuboid?If a cuboid has length = l units, breadth = b units, and height = h units, then we can evaluate the length of the diagonal of a cuboid using the formula
[tex]X^2=l^2+b^2+h^2[/tex]
As per the question the length of the straw is equal to length of the diagonal of Rectangular box.
l= 5 inch , b= 8 inch , h= 3 inch
Let us consider the length of the straw be 'x'.
As, Diagonal of Cuboid is,
[tex]X^2+l^2+b^2+h^2[/tex]
[tex]X^2=5^2+8^2+3^2[/tex]
[tex]X^2=25+64+9[/tex]

Answer:
yes thank you ..I'm sure that's is answerMultiplication is the process of multiplying. The total cost of the boxes of two types is $90.
What is multiplication?
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The cost of the first box is $12, which has 8 pounds of milk chocolate and 4 pounds of dark chocolate.
The cost of the second box is $15, which has 5 pounds of milk chocolate and 10 pounds of dark chocolate.
Therefore, if we buy the 5 boxes of the first type and 2 boxes of the second type, then the amount of two chocolate that Tim needs will be fulfilled.
The cost of 5 boxes of the first type is $60 ($12 ×5), while the cost of 2 boxes of the second type is $30 ($15×2), therefore, the total cost of the boxes of two types is $90.
