you must have 3 angles
Answer:
One.
Step-by-step explanation:
A triangle can only have one right angle because all three angles of a triangle MUST add up to be 180 degrees. That means if there are two right angles then the answer would automatically be over 180.
Example:
90+90+1=181
Therefore, a triangle can only have one right angle

Find the common difference: 1, 201, 401, 601, ... A
The common difference of the arithmetic sequence 1, 201, 401, 601, ... is 200, which is the difference between successive pairs of terms.
Explanation:In Mathematics, the common difference in an arithmetic sequence is the amount by which successive terms increase. In the given series: 1, 201, 401, 601, ..., the common difference can be found by subtracting a term from the term after it. For instance, if we subtract 1 (the first term) from 201 (the second term), we get 200. If we do the same for 201 and 401 (the second and third terms), we also get 200. This means that the common difference for this arithmetic sequence is 200.

Ted and Meg have each drawn a line on the scatter plot shown below:
Which line best represents the line of best fit?
Line P, because it is closest to most data points
Line P, because it shows a positive association
Line R, because it is closest to most data points
Line R, because it shows a negative association
Answer:
A.)Line P, because it is closest to most data points
Step-by-step explanation:
The line of best fit is a line which best represents the data and the data points are closely related to it.
It is also known as a trend line.
The line of best fit may pass through, some , none or all of the data points.
Also if the scatter plot does not pass through all the data point then the magnitude of positive residual must be approximately equal to the magnitude of negative residual of the data points.
Hence, by looking at the scatter plot we see that all the data points lie above Line R.
Hence, the Line R will not be a line of best fit.
But all the data points lie close to the line P , hence it act as a line of best fit.

Step-by-step explanation:
To solve, we need to isolate the variable, x by getting all the numbers to one sides and the variables to the other
8x-3=3x+17
Subtract 3x from both sides
8x-3x-3=3x-3x+17

triangle ABC is isosceles a= 56 degrees work out three possible values of angle B
def: -in an isosceles triangle two of its angles measure the same
- the sum of all angles in a triangle is 180°
case1: if angle a measures the same with another angle in the triangle
=>angle1=56
angle2=180-2*56=180-112=68°
from this case we extract 2 posibilities:
B=56° or B=68°
case2: if the other 2 angles beside a measure the same
angle1=angle2=(180-56)/2=62°
from this case we e extract one posibility:
B=62°
Final answer:
In an isosceles triangle ABC with angle A equal to 56 degrees, three possible values for angle B are 68 degrees if it is the vertex angle, and 56 degrees or 62 degrees if it is one of the base angles.
Explanation:
If triangle ABC is an isosceles triangle with angle A (a) equal to 56 degrees, we can work out three possible values of angle B using the properties of an isosceles triangle and the fact that the sum of angles in any triangle is 180 degrees.
Since triangle ABC is isosceles, two of its angles are equal. If angle A is one of the two equal angles, then angle B (which is the vertex angle) is given by:
B = 180° - 2AIf angle B is one of the two equal angles, then we have two cases:
B = A (the two base angles are equal)B = (180° - A) / 2 (the vertex angle is different)In the first case where angle B equals angle A (56 degrees), then the other base angle (angle C) must also be 56 degrees, and the remaining vertex angle B would be 180° - 56° - 56°, which is 68 degrees.
In the second case, where B is the vertex angle:
B = 180° - 2AB = 180° - 2(56°)B = 180° - 112°B = 68 degreesThis gives us the same value for angle B as in the first case since both result in the same configuration.
Finally, if angle B is one of the two base angles and equal to angle C, then B would be (180° - A) / 2:
B = (180° - 56°) / 2B = 124° / 2B = 62 degreesSo, three possible values for angle B are 68 degrees, 56 degrees (if B is one of the base angles), and 62 degrees (again, if B is a base angle).

On a 40 question test students gain 6 points for each correct answer and lose 0.5 points on each incorrect answer. If everyone required to give an answer to each question, what is the formulas that describes how a student's raw score, r, depends on the number of correct answers he or she provided, c?
Answer:
r=6.5c-20
Step-by-step explanation:
The raw score is given by
r=c*6-0.5(40-c)
Taking the number of correct answers as c
The incorrect answers will be 40-c
Since each incorrect answer deducts 0.5 points. Then the deducted points will be 0.5(40-c)=20-0.5c
Since correct answers, c gives 6 points each then the number of points will be 6c
Now, the raw score will be
r=6c-(20-0.5c)
Opening the brackets, the signs change hence
r=6c-20+0.5c
r=6.5c-20
The formula that describes the student's raw score based on the number of correct answers is; r = 6.5c - 20
How to solve algebra word problems?
We are told that they gain 6 points for each correct answer and lose 0.5 points for each incorrect answer. Thus, the formula for the raw score is;
The raw score is given by
r = 6c - 0.5(40 - c)
where;
c is the number of correct answers
40 - c as number of incorrect answers
We are told that each incorrect answer deducts 0.5 points.
Thus, the deducted points = 0.5(40 - c) = 20 - 0.5c
We are told that each correct answers, c gives 6 points each. Thus, the raw score will be;
r = 6c - (20 - 0.5c)
⇒ r = 6c - 20 + 0.5c
r = 6.5c - 20

What is the surface area of a cylinder that is 5 centimeters high and has a diameter of 1.5 centimeters?
A) 7.5π cm²
B) 8.625π cm²
C) 10.5 π cm²
D) 19.55π cm²
The surface area of the cylinder is 16.125π cm², which is closest to option D) 19.55π cm².
To find the surface area of a cylinder, we need to calculate the sum of the areas of its two bases and its lateral surface.
The formula for the lateral surface area of a cylinder is given by:
[tex]\[ LSA = 2 \pi r h \][/tex]
where [tex]\( r \)[/tex] is the radius and [tex]\( h \)[/tex] is the height of the cylinder.
Given that the diameter of the cylinder is 1.5 centimeters, the radius [tex]\( r \)[/tex] is half of that, which is [tex]\( \frac{1.5}{2} = 0.75 \)[/tex] centimeters.
The height of the cylinder is given as 5 centimeters.
Substituting these values into the formula for the lateral surface area:
[tex]\[ LSA = 2 \pi (0.75) (5) \][/tex]
[tex]\[ LSA = 15 \pi \][/tex]
Now, we need to find the area of the two bases of the cylinder. Since the cylinder has two circular bases, we can find their combined area using the formula for the area of a circle:
[tex]\[ A_{\text{base}} = \pi r^2 \][/tex]
[tex]\[ A_{\text{base}} = \pi r^2 \][/tex]
[tex]\[ A_{\text{base}} = \pi (0.75)^2 \][/tex]
[tex]\[ A_{\text{base}} = \pi (0.5625) \][/tex]
[tex]\[ A_{\text{base}} = 0.5625 \pi \][/tex]
The total surface area is the sum of the lateral surface area and the areas of the two bases:
[tex]\[ \text{Total Surface Area} = LSA + 2A_{\text{base}} \][/tex]
[tex]\[ \text{Total Surface Area} = 15 \pi + 2(0.5625 \pi) \][/tex]
[tex]\[ \text{Total Surface Area} = 15 \pi + 1.125 \pi \][/tex]
[tex]\[ \text{Total Surface Area} = 16.125 \pi \][/tex]
[tex]\[ \text{Total Surface Area} = 16.125 \pi \][/tex]
Therefore, the surface area of the cylinder is 16.125π cm².
The closest option is D) 19.55π cm².
In △ABC, angle C is a right angle and BC > AC. Select all the statements that are true.
A. m∠B > m∠A
B. sin A > sin B
C. sin A < sin B
D. cos A > cos B
E. cos A < cos B
△ABC right angle C, leg BC > leg AC. So angle A > angle B.
a=BC, b=AC, c=AB
a > b
sin A= cos B = a/c
sin B = cos A = b/c
a = c sin A = c cos B
b = c sin B = c cos A
a > b
c sin A > c sin B
sin A > sin B
c cos B > c cos A
cos B > cos A
Answer: B, E
Final answer:
In a right-angled triangle △ABC with BC > AC, it is true that m∠B > m∠A, sin A < sin B, and cos A > cos B. These correspond to choices A, C, and D.
Explanation:
In the context of triangle △ABC where angle C is a right angle and BC > AC, we can assess the truth of various statements regarding the angles and their sine and cosine values:
m∠B > m∠A: This statement is true because in a right-angled triangle the side opposite the right angle is the hypotenuse and is the largest side. Therefore, the angle opposite the longest side (BC) must be the largest acute angle, hence m∠B > m∠A.
sin A > sin B: This statement is false. Since m∠B > m∠A and sine of an angle increases with the angle's magnitude (for acute angles), it must be that sin A < sin B.
sin A < sin B: This statement is true based on the relationship of the sides and angles mentioned earlier.
cos A > cos B: This statement is true. Since m∠B > m∠A and cosine of an angle decreases as the angle's magnitude increases (for acute angles), it must be that cos A > cos B.
cos A < cos B: This statement is false for the same reason that cos A > cos B is true.
The correct statements are therefore A, C, and D.
(9 – 6i) × m = 9 – 6i

1
9 + 6i
-9 + 6i
To solve for m in the equation (9 – 6i) × m = 9 – 6i, both sides are divided by (9 – 6i), yielding m = 1.
Explanation:The equation given is (9 – 6i) × m = 9 – 6i. To find the value of m, we can divide both sides of the equation by (9 – 6i). Doing so, we get:
m = (9 – 6i) / (9 – 6i) = 1.
Therefore, the value of m is 1.

Answer:
1. C.
2. B.
3. A.
Step-by-step explanation:
First situation given:
An adult and 5 children rent skates. It costs $ 4 per adult for skates and a total of $ 16.
Correct equation: C
4 + 5 x = 16
Second situation given:
It costs Mikael $ 4 to make a bike bag, and he sells each for $ 5. He has made a profit of $ 16, so far.
Correct equation: B
( 5 − 4 ) x = 16
Third situation given:
It was 16°C. It began falling 4°C per hour until it reached 5°C.
Correct equation: A
16 − 4 x = 5
Equations are matched to situations based on the context provided: the adult and children renting skates is described by 4 + 5x = 16, Mikael's profit from selling bike bags fits the equation (5 - 4)x = 16, and the temperature dropping over time corresponds to 16 - 4x = 5.
To match each equation to its corresponding situation, let us consider each situation and then associate the relevant equation.
Adult and children renting skates: An adult rents skates at $4, and the total cost including 5 children is $16. The equation representing the total cost is the adult's cost plus 5 times the children's cost equals $16, which is: 4 + 5x = 16.
Mikael making a profit from bike bags: Mikael spends $4 to make a bike bag, sells it for $5, and has made a profit of $16. To determine how many bags he sold (x), we can use the equation that accounts for profit, which is the selling price minus the cost of making the bag, multiplied by the number of bags, equals the profit: (5 - 4)x = 16.
Temperature drop: The temperature started at 16°C and dropped at a rate of 4°C per hour until it reached 5°C. To find the number of hours (x) it took for the temperature to drop, we can use the equation that links the initial temperature, minus the drop per hour times the number of hours, equals the final temperature: 16 - 4x = 5.
Now, we can clearly match the equations to their situations:
The situation where an adult and children rent skates corresponds to the equation 4 + 5x = 16.
Mikael making a profit from selling bike bags is represented by the equation (5 - 4)x = 16.
The decrease in temperature over time until it reached 5°C is described by the equation 16 - 4x = 5.

What is the equation for ⊙A?
Answer:
Circumference = 3.14 diameter C = 3.14(6) Answer: 18.84
Step-by-step explanation:
The equation for circle at A is (x+4)²+(y+2)²=9 whose radius is 3 units.
The equation of the circle is (x-h)²+(y-k)²=r²
Where h and k are the coordinates of centre of circle and r is radius of the circle.
From the given figure (h, k) is (-4, -2) and r is 3 units
Plug in these values in the equation of circle.
(x-(-4))²+(y-(-2))²=3²
(x+4)²+(y+2)²=9
Hence, the equation for circle at centre A is (x+4)²+(y+2)²=9 whose radius is 3 units.
