Answer:
92
Step-by-step explanation:
88 + C = 180
-88 -88
C and B = 92
C is vertical to b so therefore they both have the same value which is 92.
Answer:
c and b are both 92°
Step-by-step explanation:
the straight line equals 180°.
take 180-88= 92°
b= 92°
then, you see how c is a vertical angle, across from b?
thus, making c= 92° also!

Answer:
90
Step-by-step explanation:
8*5 = 40
40 + 5 = 45
1/2 x = 45
x = 90
Answer: 90 apples
Step-by-step explanation: If Mat sold 8 times as many apples as how much he gave to his son, this means he sold 40 apples. Altogether, he loses 45 apples (5 to his son, 40 sold), and this is 1/2 of the original numbers of apples. Hence, the original number of apples was 90

The mean of eight numbers is 41. The mean of two of the numbers is 29. What is the mean of the other six numbers
Answer:
45
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Given the mean of 8 numbers is 41 , then
[tex]\frac{sum}{8}[/tex] = 41 ( multiply both sides by 8 )
sum of 8 numbers = 328
Given the mean of 2 numbers is 29 , then
[tex]\frac{sum}{2}[/tex] = 29 ( multiply both sides by 2 )
sum of 2 numbers = 58
The sum of the remaining 6 numbers = 328 - 58 = 270 , so
mean = [tex]\frac{270}{6}[/tex] = 45
The mean of the other 6 numbers = 45

The formula for the nth term of the arithmetic sequence first term is 9 common difference is -2
Answer:
[tex]a_n = 9 - 2(n-1)[/tex]
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.
The nth term is given by the following equation:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term and d is the common difference.
First term is 9 common difference is -2
This means that [tex]a_1 = 9, d = -2[/tex]
So, the nth term is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
[tex]a_n = 9 + (n-1)(-2)[/tex]
[tex]a_n = 9 - 2(n-1)[/tex]

Answer:
A. x^2 +(y -7)^2 = 625
B. S'(39, 20)
C. P'(19, 35)
D. C'(56.5, 17.5)
Step-by-step explanation:
Part A: The infinite number of points with those coordinates will be the solutions to the equation of a circle centered at Q with radius 25. The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
For (h, k) = (0, 7) and r=25, the equation for the points of interest is ...
x^2 +(y -7)^2 = 625
__
Part B: It is useful to recognize ΔROQ as a right triangle with sides that are the Pythagorean triple (7, 24, 25). (You can figure side RO using the Pythagorean theorem if you're not familiar with this triple.) This means the coordinates of R are (24, 0) and the horizontal distance to the line x=39 is 39-24=15 units.
If we name point X(39, 0), then triangle RXS' has sides RX = 15 and RS' = 25. We recognize these as a multiple of the Pythagorean triple (3, 4, 5), so we know that XS' = 20, (Again, you can figure this using the Pythagorean theorem if you're not familiar with the relevant triples.)
The coordinates of S' are (39, 20).
__
Part C:
Point S' is 15 right and 20 up from R. A vector at right angles to RS' will have the coordinates swapped, and one of them negated. Point P' will be 20 left and 15 up from point S', so ...
P' = S' +(-20, 15) = (39, 20) +(-20, 15) =
P' = (19, 35)
__
Part D: After rotation, the center (C) of the square is the midpoint of RP', so is ...
C = (R +P')/2 = ((24, 0) +(19, 35))/2 = (43, 35)/2 = (21.5, 17.5)
Reflection over the line x=39 is accomplished by the transformation ...
(x, y) ⇒ (2·39 -x, y)
C(21.5, 17.5) ⇒ C'(78 -21.5, 17.5) = C'(56.5, 17.5)

Step-by-step explanation:
taking 28 degree as reference angle . Then
sin 28 = opposite/hypotenuse
sin 28 = 8/17
The value of sin 28° is 8/17.
How to estimate the value of sin 28°?In the right triangle of the figure
Let, x be the opposite side angle of 28°
and y be the hypotenuse
[tex]$\sin \left(28^{\circ}\right)=\frac{x}{y}$[/tex]
We have,
x = 8 units and
y = 17 units
Substitute the values of x and y, we get
[tex]$\sin \left(28^{\circ}\right)=\frac{8}{17}$[/tex]
Therefore, the correct answer is option D. 8/17.

Explanation:
The three Reasons tell you what to look for to put in the Statement blank.
1. We are given that RE = 2AR and RT = 2GR.
2. The only vertical angles in the figure are ...
∠GRA ≅ ∠TRE
3. Using the given relation between the sides, we can write the proportion ...
RE/RA = RT/RG = 2
It is nice, though maybe not absolutely essential, to write the segment names in order of corresponding vertices.
4. Having shown that two sides are proportional and the angle between them is congruent, we can claim similarity using the SAS Theorem.

what is the mean of these numbers:3,5,7,9
Answer: 6
Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.
Let's begin by adding the numbers to get 24.
Now we divide 24 by the number of numbers in the set or 4.
So we have 24/4 which is 6.
Therefore, the mean of the data set is 6.

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 35 hours and the median is 31.2 hours. Twenty-four of the families in the sample turned on the television for 20 hours or less for the week. The 12th percentile of the data is 20 hours. Step 1 of 5: Based on the given information, determine if the following statement is true or false. The 55th percentile is greater than or equal to 30 hours.
1: Approximately how many families are in the sample? Round your answer to the nearest integer.
2: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
3: What is the value of the 50th percentile?
4: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
Answer:
Step 1: True
1. Approximately 2000 families are in the sample.
2. False.
3. 31.2 hours.
4. False.
Step-by-step explanation:
The 55th percentile is greater than or equal to 30 hours.
The median is of 31.2 hours, which means that the 50th percentile is of 31.2 hours. The 55th percentile is above the 50th percentile, and thus, the 55th percentile is greater than 31.2 hours, and thus, also greater than 30 hours, and the statement is true.
1: Approximately how many families are in the sample?
Twenty-four of the families in the sample turned on the television for 20 hours or less for the week. The 12th percentile of the data is 20 hours, and thus 24 is 12% of the sample size n. So
[tex]0.12n = 24[/tex]
[tex]n = \frac{24}{0.12}[/tex]
[tex]n = 2000[/tex]
Approximately 2000 families are in the sample.
2: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
The median, that is, the 50th percentile, is of 31.2 hours.
Thus, 35 hours is above the 50th percentile, which means that more than 1000 families(considerably more than 200) will have turned on their TVs for less than 35 hours, and this statement is false.
3: What is the value of the 50th percentile?
The median, which is of 31.2 hours.
4: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
20 hours is the 12th percentile, which means that the first percentile is less than 20 hours, and this statement is false.

fine t12 term in an arithmetic progression having t3=10 and t10=-4
✍ Having as t₃ =10 and t₁₀ = -4. We have to find the common ratio.
❑ If, in front of the sequence from 3 to 10, there are 7 numbers, that is, 7 terms, we have to find a pattern, what I used was this one.
[tex]\large {\text {$ \sf 7 \longrightarrow Number \: Terms $}}[/tex]
[tex]\large {\text {$ \sf x \longrightarrow rasion $}}[/tex]
We see that in the calculation, the only number that fits is -2.
➤ Because if we stop to think about it, we have -2 of common ratio among these 7 terms is -14, so 10-14 = -4
So the hypothesis is correct!
➜ Being right as -2 and resuming the terms of 10, we have:
[tex]\huge {\boxed {\blue {\sf t_{10}, t_{11}, {\bf t_{12}} = \{ -4 , -6 , \bf -8 \} } }}[/tex]
So t₁₂ is equal to -8.

Which of the following changes would double the force between two charged particles?
A. Doubling the amount of charge on each particle
B. Increasing the distance between the particles by a factor of 2
C. Decreasing the distance between the particles by a factor of 2
D. Doubling the amount of charge on one of the particles
Answer:
D. Doubling the amount of charge on one of the particles
Step-by-step explanation:
Force between charged particles:
The force between two charged particles is given by:
[tex]F = \frac{kq_1q_2}{r^2}[/tex]
In which k is the coulomb constant, [tex]q_1[/tex] and [tex]q_2[/tex] are the charges and r is the distance between them.
Which of the following changes would double the force between two charged particles?
Doubling the amount of force on both particles quadriplies, as does decreasing the distance between the particles by a factor of 2(we would have a division by 1/4 which is the same as a multiplication by 4).
Increasing the distance would decrease the force.
So the correct option is D, one of the particles' charges being multiplied by 2 means that the equation for F is multiplied by 2, and thus, the force is doubled.
