What is the largest Angle of BCD?
Answer:
< C
Step-by-step explanation:
because 23 is the largest number on the triangle so the angle opposite of that side would be C
Solve the system of equations using subtraction. Equation 1: 3x-2y= -2 Equation 2: 3x + y = 10 The solution is (? ,?) HURRY PLEASE!!!!
Answer:
the solution is x = 2 and y = 4 OR (2,4)
Step-by-step explanation:
From the question
Equation 1: 3x-2y= -2
Equation 2: 3x + y = 10
Subtract equation 1 from equation 2, that is
3x + y = 10 - (3x -2y = -2)
You get
3x - 3x + y - (-2y) = 10 - (-2)
0 + y + 2y = 10 + 2
3y = 12
Divide both sides by 3
∴ y = 12/3
y = 4
Substitute the value of y into equation 2 to get x
3x + y = 10
3x + 4 = 10
Then,
3x = 10 - 4
3x = 6
Divide both sides by 3
∴ x = 6/3
x = 2
Hence, the solution is x = 2 and y = 4

A traffic light is green for 2 minutes, red for 40 seconds, and yellow for 10 seconds. When a car approaches the light, what is
the probability that it is not red?
here total second=170 second
probability that is not red=
[tex] \frac{12}{284} [/tex]
Step-by-step explanation:
i think that is the portability that is not red
The probability that the light is not red is 13/17
How to determine the probability?The given parameters are:
Green = 2 minutes
Red = 40 seconds
Yellow = 10 seconds
Express green as seconds
Green = 120 seconds
The probability that the light is red is:
P(Red) =Red/Total
This gives
P(Red) = 40/(120 + 40 + 10)
Divide
P(Red) = 4/17
The probability that it is not red is:
P(Not Red) = 1 - P(Red)
This gives
P(Not Red) = 1 - 4/17
Subtract
P(Not Red) = 13/17
Hence, the probability that the light is not red is 13/17

i put the image of the question, PLS HELP
Answer:
A translation is when you move in a direction but the shape doesn't turn or change.
You translate an image by moving a shape in any direction without turning it for example: *draw a shape* then move it to anywhere but don't turn the shape.
An easy way of finding the new coordinates is just by looking to which respect it's too. For example when you do a respect to the y axis you keep the second number in the coordinate pair and change the first number's sign in the coordinate pair same to the x axis.
It depends on their sign. Change in x-coordinate. Change in y-coordinate. Right. Increases. No Change. Left. Decreases. No Change. Up. No Change. Increases. Down. No Change. Decreases .
We use vectors to represent a translation. Which means we need direction (up, down, left, or right) and magnitude (length of units).
company that manufactures a popular multivitamin wanted to determine whether their multivitamin had any side effects. For its initial study, the company chose 2000 individuals to take one of their multivitamin tablets per day for one year. Scientists from the company surveyed the participants to determine whether they had experienced any side effects. The greatest problem with this procedure is that A) only one brand of vitamin was tested B) the study lasted only one year C) the sample size was not large enough D) no control group was used
Answer:
Option D
Step-by-step explanation:
In this experiment, It would have been scientific to compare the result of the experiment on the experimental group(taking the multivitamin) with the control group (Taking no medicine)
Without a control group, a defined impact of multivitamin over the experimental group cannot be deduced.
Hence, option D is correct

Solve for unknown values.
X= degrees
Y= degrees
Answer:
X = 85°
Y = 45°
Step-by-step explanation:
95° + x = 180° [angles on a straight line]
x = 180° - 95°
x = 85°
50° + x + y = 180° [sum of angles in a triangle]
50° + 85° + y = 180°
135° + y = 180°
y = 180° - 135°
y = 45°

An airplane takes off at an angle of 15 degrees with the ground. To the nearest 10 feet, how far has the airplane flown when it has covered a horizontal distance of 1800 feet?
Answer:
1863.5 feets
Step-by-step explanation:
Using Trigonometry :
The distance, d in the attached diagram can be obtained using the trigonometric relation :
Cosθ = adjacent / hypotenus
Cos 15° = 1800 / d
0.9659258 = 1800 / d
0.9659258 * d = 1800
d = 1800 / 0.9659258
d = 1863.4971 feets
The distance covered to the nearest 10 feet = 1863.5 feets

Answer:
B
Step-by-step explanation:
the second option!
Answer:
It would be 360/n
Step-by-step explanation:
Every shape's exterior angles must combine to form a 360* shape (meaning "full-circle" even though they are not circles). So you must divide 360 by the number of angles a shape has.
Ex #1: A Square has four angles, so the equation to finding the degrees of each exterior angle is 360/4, which equals 90. So 90* per exterior angle.
Ex #2: A Decagon has 10 angles, so the equation to finding the degrees of each exterior angle is 360/10, which equals 36. So 36* per exterior angle.

A person places $123 in an investment account earning an annual rate of 2.8%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the
nearest cent, in the account after 2 years.
Answer:
V = 130.08
Step-by-step explanation:
To solve we will use the equation V= [tex]Pe^r^t[/tex]
V= what you are solving for
P= initial number ( 123)
R= rate (2.8%)
-we can convert the rate to a decimal by moving the decimal place 2 spaces to the left.
R= 0.028
T= time (2 years)
The equation should be... [tex]V=123e^(^0^.^0^2^8^*^2^)[/tex]
To solve we can first multiply 0.028 and 2
This is = 0.056
[tex]V=123e^0^.^0^5^6[/tex]
Then using a calculator we get...
V = 130.0845
Taylor bought 48 of marshmallows to the bonfire. Taylor and 10 of her friends made s’mores with them. At the end of the night, there were 9 bags left. How many bags of marshmallows did Taylor and her friends go through? (Write the operation and the answer)
Answer:
The operation used is the Subtraction operation
39 bags of marshmallows
Step-by-step explanation:
The operation we would be using here is the Subtraction operation.
Total number of bags if Marshmallows bought = 48 bags
Number of people present = Taylor + 10 friends = 11 people
Amount of Marshmallows left = 9 bags
Hence, the number of bags of marshmallows that Taylor and her friends went through is calculated as:
48 bags of marshmallows - 9 bags of marshmallows
= 39 bags of marshmallows

The Hiking Club plans to go camping in a State park where the
probability of rain on any given day is 30%. What is the probability
that it will rain on exactly one of the five days they are there? Round
your answer to the nearest thousandth.
Answer:
0.013
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
and p is the probability of success.
Given n = 6, p = 0.69, and r = 0 or 1:
P = ₆C₀ (0.69)⁰ (1−0.69)⁶⁻⁰ + ₆C₁ (0.69)¹ (1−0.69)⁶⁻¹
P = (1) (1) (0.31)⁶ + (6) (0.69) (0.31)⁵
P = 0.013
