what is the measure of <1?
Answer:
∠ 1 = 72°
Step-by-step explanation:
(4n - 2) and (2n + 17) are adjacent angles and sum to 180° , that is
4n - 2 + 2n + 17 = 180
6n + 15 = 180 ( subtract 15 from both sides )
6n = 165 ( divide both sides by 6 )
n = 27.5
Then
2n + 17 = 2(27.5) + 17 = 55 + 17 = 72
∠ 1 and 2n + 17 are vertical angles and congruent , so
∠ 1 = 72°

Answer:
$81.92
Step-by-step explanation:
Week 1:
250 * 20% = 50
250 - 50 = 200
Week 2:
200 * 20% = 40
200 - 40 = 160
Week 3:
160 * 20% = 32
160 - 32 = 128
Week 4:
128 * 20% = 25.6
128 - 25.6 = 102.4
Week 5:
102.4 * 20% = 20.48
102.4 - 20.48 = 81.92
Helpppppp pleaseeeee illl give brainliest answer if u know dont answer if youuuu don’t know and pleaseeee just don’t give me a virus helppp
Answer:
There are two possible outcomes when flipping a coin. The theoretical probability that you will get "heads" when flipping a coin is 50%. If you, for example, got 26 tails and 24 heads, then the experimental probability of getting heads is 48%.
Step-by-step explanation:
There are two outcomes - heads or tails. In theory, you have a 50% chance of getting heads because half the time you should get heads, and the other half you should get tails. If you actually flipped a coin fifty times, there's a good chance it would not actually be 50/50. In the example, I flipped a coin fifty times and got tails 26 times and heads 24 times. Since we flipped it fifty times, we just have to double these numbers to figure out the percentage (because then it will be like I flipped it one hundred times, to make 100%). 26 × 2 = 52 and 24 × 2 = 48. So when I actually experimented, there was a 52% chance of me getting tails and 48% chance of me getting heads.

Hayden went apple picking with his family. In his bag he had four Granny Smith apples,
two Honeycrisp apples, three Gala apples, and one Fuji apple. What is the probability
that he will pick a Granny Smith apple out of his bag, replace it, and then choose a
Honeycrisp apple? Write your answer as a simplified fraction.
Answer: [tex]\dfrac{2}{25}[/tex]
Step-by-step explanation:
Given
There 4 Granny smith, 2 Honey crisp, 3 Gala, 1 Fuji apples in the bag
The chance of picking a granny smith apple out of the bag is 4 out of 10 apples
So, the probability of picking it is [tex]\frac{4}{10}[/tex]
now, it is replaced and honey crisp apple is chosen
The probability of happening this event along with the first one is
[tex]\Rightarrow P=\dfrac{4}{10}\times \dfrac{2}{10}\\\\\Rightarrow P=\dfrac{8}{100}=\dfrac{2}{25}[/tex]

Answer:
x = 4.5
Step-by-step explanation:
Since the perimeters are equal , then the equation relating them is
2x + 3 + 2x - 3 + x = x + 3 + x + 3 + x + 3 , that is
5x = 3x + 9 ( subtract 3x from both sides )
2x = 9 ( divide both sides by 2 )
x = 4.5
The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
Answer:
Future Value = $ 12528.15
Step-by-step explanation:
The depreciation is applied to the car annually. The value of the car after depreciation in "n" no. of years can be given by the following formula:
[tex]Future\ Value = (Present\ Value)(1-depreciation\ rate)^n\\[/tex]
where,
Future Value = ?
Present Value = $ 24000
Depreciation Rate = 15% = 0.15
n = no. of years = 4
Therefore,
[tex]Future\ Value = (\$ 24000)(1-0.15)^4[/tex]
Future Value = $ 12528.15
Analyze Information The fastest first-round time for the women's 100-meter hurdles in the Olympics was set in 2012 at 12.54 seconds. What digit is in the tenths place? In the hundredths place?
Answer: 5 is in the tenths place
4 is in the hundredths place.
Step-by-step explanation:
When dealing with the place value of numbers, we should note that the digit is in the tenths place is the first didgut after the decimal point. In the number 12.54, the first digit after the decimal place is 5.
The digit in the hundredths place is the digit that comes immediately after the tenths place. In this case given the number 12.54, the digit in the hundredths place is 4.

the decimal expansion of rational number 543 by 2 raised to 4 multiplyed by 5 raised to 3, will terminate after how many places of decimal.
Answer:
4Step-by-step explanation:
543 / (2⁴*5³) = 543 / (16*125) = 543 / 2000 = 0.2715This is terminated after 4 places of decimal
Answer:
Step-by-step explanation:
In the decimal expansion of a rational number, the general rule is that if the denominator is of the form 2^m*5^n, then it will terminate after n places if n>m or m places if m>n.
In this case, 4 > 3 so the expansion will terminate after 4 decimal places.

1 Marlena has a bag of coins. The bag
contains 8 quarters, 10 dimes, 4 nickels,
and 2 pennies. She will randomly select a
coin from the bag. What is the probability
that Marlena will select a nickel? (7.1A,
7.1B, 7.1F)
Answer:
The probability is 1/6
Step-by-step explanation:
Firstly, we need to get the total number of coins
that would be the sum of all the coins present
We have this as;
8 + 10 + 4 + 2 = 24 coins
The number of nickels is 4
So the probability of selecting a nickel is the number of nickels divided by the total number of coins
We have this as;
4/24 = 1/6

Triangle ABC has AB = 10 √3cm, AC=6cm and has area 45cm^2
(i) Find the size of angle CAB.
(ii) Find the length of BC
Answer:
I) ∠CAB measures 60°.
II) BC measures approximately 15.23 cm.
*Please read notes.
Step-by-step explanation:
We are given ΔABC, where AB measures 10√3 cm, AC measures 6 cm, and the triangle has an area of 45 square cm.
And we want to find I) the measure of ∠CAB and II) the length of BC.
I) First, we should always draw a representative triangle so we can determine the sides and angles. This is shown below.
Note that ∠CAB (or simply ∠A) is the angle between the two sides. Thus, we can find the angle by using the alternative formula for the area of a triangle:
[tex]\displaystyle A=\frac{1}{2}ab\sin(C)[/tex]
Where a and b are two side lengths, and C is the angle between the two sides.
Substitute:
[tex]\displaystyle 45=\frac{1}{2}(10\sqrt{3})(6)\sin(A)[/tex]
Simplify:
[tex]\displaystyle 45=30\sqrt{3}\sin(A)[/tex]
So:
[tex]\displaystyle \sin(A)=\frac{45}{30\sqrt{3}}=\frac{3}{2\sqrt3}=\frac{\sqrt{3}}{2}[/tex]
Take the inverse sine of both sides. Use a calculator. Thus:
[tex]\displaystyle m\angle A=\sin^{-1}\left(\frac{\sqrt{3}}{2}\right)=60^\circ[/tex]
II) To find BC, we will use the Law of Cosines. We do not know whether or not ΔABC is a right triangle, so we cannot use right triangle trigonometry or special right triangles.
The law of cosines is:
[tex]\displaystyle c^2=a^2+b^2-2ab\cos(C)[/tex]
Where a and b are side lengths and C is the angle between the side lengths. c is the side length opposite to the angle.
BC is opposite to A. Substitute:
[tex](BC)^2=(10\sqrt{3})^2+(6)^2-2(10\sqrt{3})(6)\cos(60^\circ)[/tex]
Simplify:
[tex]\displaystyle BC^2=336-120\sqrt{3}\left(\frac{1}{2}\right)=336-60\sqrt{3}[/tex]
Take the square root of both sides:
[tex]\displaystyle BC=\sqrt{336-60\sqrt{3}}\approx 15.23[/tex]
BC measures about 15.23 cm.
Notes:
In this case, the inverse sine of √3/2 will yield two answers: 60° and 120°. This is an example of an ambiguous case. Both of these angles will work. However, BC will be different. If ∠A is 60°, then BC is about 15.23. However, if ∠A is 120°, then BC is about 20.97. Both will result in the triangle having an area of 45 square cm, as well as AB measuring 10√3 and AC measuring 6.
a. 15 * (6 + 4) = (15 * ■) + (15 * 4)
b. 2 * (x + 6) = (2 * ■) + (■ * 6)
c. (x * 2) + (x * 6) = ■ * (2 + 6)
Answer:
A)6
B)x 2
C)x

Answer:
BELOW
Step-by-step explanation:
SO lets think about the information they give us.
Khan acadamy says that we have -3 x and 5 x.
So that just means that the quadratic at 0 has one curved line at -3x and another at 5x. Note that you should put the green dot on the top right on either -3x or 5x to do this.
Then they say the minimum is -4 y.
This just means that when x is 0, y should be -4. Note that you should put the midddle bottom green dot at -4 y exactly on the black line, which is at 0 x.
Green dot top right: (-3 or 5, 0)
Green dot middle bottom: (0, -4)

Please help me so i don't fail :(
Answer:
y = 2x + 6
Step-by-step explanation:
slope-intercept form => y = mx + b
substitute two of the (x, y) into the equations: y = mx + b to solve for m and b
=> 0 = -3m + b, 6 = 0m + b
6 = 0m + b => b = 6
substitute b = 6 into 0 = -3m + b to solve for m:
=> 0 = -3m + 6 => -3m = -6 => m = 2
plug in b = 6 and m = 2 into the equation y = mx + b:
=> y = 2x + 6
Students are trying to determine the height of the flagpole at Arlington High. They have measured out a horizontal distance of 40 feet from the flagpole and site the top of it at an angle of elevation of 52o. What is the height, h, of the flagpole? Round your answer to the nearest tenth of a foot.
Answer:
51.2feet
Step-by-step explanation:
Given;
Horizontal distance = 40feet (Adjacent)
Angle of elevation = 52 degrees
Required
Height of the pole H (Opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 52 = H/40
H = 40tan 52
H = 40(1.2799)
H = 51.2 feet
Hence height, h, of the flagpole to the nearest tenth is 51.2feet
