Answer: The answer the second option
Step-by-step explanation:Because since 270 degrees counterclockwise is equal to 90 clockwise you would use the 90 formula and swap the x and y and add a negative to the x and if you do that with each on the second d option should match you answer exactly.

Solution = 24 mice
Step-by-step explanation:
The ratio of brown mice to white mice is 5:3 this means the number of brown to white mice has to double until there is 6 more brown mice than white mice.
For example:
5:3
10:6

15 + 9 = 24
Therefore, there are 24 mice at the store.

There's one triangle satisfying angle BCA = 60 degree, AB = 12 and AC = 10 shown below:
The only possible value of BC is a, as shown above. What is a?
Answers
Answer:
13.3
Step-by-step explanation:
draw a line from A to be perpendicular to line BC
which will cut a into 2 parts. call it a1, & a2
so now you have 2 right angle triangle - left side one with an angle known 60°, which means the top angle after the separation is 30° & something else, we don't care that part.
any right angle triangle with 30-60-90 ° has a property of shorter side = 1/2 of the long side. so right away we know a1= 5. and the perpendicular line = 5√3. this property you should memorize.
now solve a2. look at the triangle on the right.
because we know the perpendicular line is 5√3, and long side =12
so (a2)² = 12² - (5√3)² =144-75 =69
so a2 = 8.3
so a = a1+a2 = 5+8.3 =13.3
Answer:a = 13.31

find x and y intercept
Answers
Y Intercept = (0,-8)
Answer:
x-intercept: (-6,0)
y-intercept: (0,-8)
Step-by-step explanation:
The x-intercept is when y = 0.
The y-intercept is when x = 0.
Each intercept can be solved with substitution in the standard form equation.
Given the re-arranged standard form equation is
-3y = 4x + 24
With a standard form equation being in the form:
Ax + By = C.
-3y = 4x + 24 →
-3y – 24 = 4x + 24 – 24 →
-3y – 24 = 4x →
-3y + 3y – 24 = 4x + 3y →
-24 = 4x + 3y →
4x + 3y = -24
x-intercept:
given y = 0
4x + 3(0) = -24 →
4x = 24 →
4x / 4 = -24 / 4 →
x = -6 →
(-6, 0)
y-intercept:
given x = 0
4(0) + 3y = -24 →
3y = -24 →
3y / 3 = -24 / 3 →
y = -8 →

On a scavenger hunt, you find 16 out of 20 objects. Write "16 out of 20" as a fraction in simplest form, a decimal, and a percent.
Answers
Decimal: 0.8
Percentage:8
Hi there, here's your answer:
According to the question, we find 16 out of 20 objects.
To express this in a fraction at its simplest form,
We first write down the fraction.
[tex]\frac{16}{20}[/tex]
The HCF of 16 and 20 is 4.
On dividing the numerator and denominator by 4, we get: [tex]\frac{4}{5}[/tex]
To express [tex]\frac{4}{5}[/tex] as a decimal:
Observe the denominator. We know that 5×2 = 10
On multiplying the numerator and denominator by 2, we get [tex]\frac{8}{10}[/tex]
Which, in decimal form, is 0.8
To express [tex]\frac{16}{20}[/tex] as a percentage,
We simply multiply the fraction by 100.
[tex]\frac{16}{20}[/tex] × [tex]100[/tex] [tex]= 16[/tex] × [tex]5 = 80[/tex]%
Therefore, 16 out of 20 in percentage is written as 80%.

the value of the x and y for the given system of equations are 6, and -2 respectively.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given, a system of equations
2x + 5y = 2
2x - 5y = 22
Adding both equations:
4x = 24
x = 6
From equation 1
2 * 6 + 5y = 2
5y = -10
y = -2

Suppose you have two bank accounts. In Account A you deposit $100. In Account B you deposit $300. Account A has a simple interest rate of 4.3%. Account B has a simple interest rate of 2.1%. One year later, you get a bank statement from each bank and one of the statements shows an incorrect amount of interest. The interest for Account A is $4.30. The interest for Account B is $630. Which account statement is incorrect? Find the bank's likely error.
Answers
The interest for Account B is likely incorrect.
The interest for Account A can be calculated as follows:
$100 * 4.3% = $4.30
The interest for Account B should be calculated as follows:
$300 * 2.1% = $6.30
Since the interest for Account B is much higher than it should be, the statement from that account is likely incorrect. The bank's likely error is overstating the interest earned on Account B.

The radius of the base of the cone is √189 ft.
What is the Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.
For question 5 :
Given a right-angle triangle that has a hypotenuse of 14 and a base is 9 cm.
From the Pythagorean theorem:
Hypotaneuse² = base² + height²
14² = 9² + height²
height² = 196 - 81
height² = 115
height = √115
For question 4:
The distance from the top of the cone to the edge is 15 feet. The height of the cone is 6 feet.
The radius of the cone = base pf right angle triangle
From the Pythagorean theorem:
Hypotaneuse² = base² + height²
15² = base² + 6²
225 - 36 = base²
base = √189

question 2: take 40 + 90 = 130, then subtract 180 - 130 = 50. x = 50 degrees
question 3: the ratio 4:4:10 can be converted to angles of a triangle, 45, 45, 90. this means that angles F and G will equal 45 degrees, and angle H will equal 90 degrees
question 4: this is finding the coterminal angle to get the answer. we know that angle 1 is 42 degrees, so we want to subtract 90 - 42 to get 48. coterminal angles in an example like this need to add up to 180 degrees. so we subtract 180-48 to get 132 degrees. angle 2 = 132 degrees
question 5: using what we did last problem, we can take angle 4 and find the coterminal angle which is 180-74=106 degrees. we can then add angles 2 and 3 together (106+43) which gives us 149 degrees. subtract 180-149= 31. angle 1= 31 degrees and angle 2= 106 degrees
The measure of <1 is 31 degree and measure of <2 is 106 degree.

Emily noticed that on halloween, her child got three basic types of candy: chocolate, gummy, and hard candy. She has 15 more hard candies that chocolate, and 5 less than twice the amount for gummy candy than chocolate. if she had a total of 178 pieces of candy, how many of each type did she get?
Answers
Answer: gotta scroll down sry
Step-by-step explanation:
First set up equations with variables that show the information you have:
c = chocolate // g = gummy // h = hard candy
178 = c + g + h
h = c + 15
g = 2c - 5
Then, solve all the equations for a number:
178 = c + g + h (leave as is)
15 = -c + h (subtract 'c' from the original equation's right side and switch the sides of the equation)
-5 = -2c + g (subtract '2c' from the original equation's right side and switch the side of the equation)
Then, line up all the variables and subtract the top equation by the lower two:
178 = c + g + h
15 = -c + 0g + h
-5 = -2c + g + 0h
---------------------------
168 = 4c + 0g + 0h >>>> 168 = 4c
Solve for 'c' and plug it into the other equations to find 'h' and 'g':
168/4 = 4c/4
42 = c
15 = -(42) + h -5 = -2(42) +g
57 = h 79 = g
Add all the numbers together to double-check:
42 + 57 + 79 = 178
chocolates = 42
gummies = 79
hard candies = 57
