Answer:
∠B` = 109.73°, ∠B = 70.27°
Step-by-step explanation:
∠B + ∠B` = 180°
The Sine Law:
10 / sin B` = 9.2 / sin 60°
10 / sin B` = 9.2 / √3/2
sin B` = 0.94133
B` = sin^(-1) 0.94133
∠B` = 109.73°, ∠B = 70.27°
Find the first six terms of the sequence. a1 = 7, an = an-1 + 6
Answer:
7, 12, 17, 21, 26, 31
Step-by-step explanation:
The first term in the sequence is 7 we know this cause the first equation (a1 = 7) is telling us what the first term is. To find the next term we use the second equation (an = an - 1 + 6) we us the first term subtract 1 and then add 6 ( 7 - 1 = 6, 6 + 6 = 12) the second terms is 12. To find the rest of the terms we continue using the second equation but instead of with 7 this time we use 12 then the next time 17 then 21 then 26 so on and so forth.

Based on the sample of 8th graders in the table, how many of the 350 students in 8th grade will like Pop/Rock as their favorite type of music?
Answer:
168
Step-by-step explanation:
Out of the 12 + 7 + 6 = 25 students sampled, 12/25 = 48% students liked Pop/Rock so 48% of 350 = 168 students is the answer.
Answer: 168 students
Step-by-step explanation:
12 + 7 + 6 = 25 so if we add all the numbers we get 25 then
we put it as 12/25 which is
48% students liked Pop/Rock
so then we do 48% of 350 or divide and get
168 students

Find the value of each variable. Be sure to explain your answers.
a ⋅ 3 = - 30
-9 ⋅ b = 45
-84 ⋅ 12 = c
d ⋅ 88 = -88,000
a =
b =
c =
d =
Answer:
a = -10
b = -5
c = -1008
d =-1000
Step-by-step explanation:
a = -30/3
b = 45/-9
c = -84x12
d = -88000/88
Answer: A = -10. B = 54. C = -1008. D = -1000
Step-by-step explanation:
a * 3= - 30 You must divide 3 on both sides in order to get the a alone.
a * 3/3= - 30/3 And once you divide 3 from both sides you end up with
a= -10 And a equals negative 10
-9 * b = 45 You have to add 9 to both sides to get b alone.
-9 +9 *b= 45 +9 And you end up with with
b= 54 b equals 54
-84 * 12= c Since the c is already alone all you have to do is solve the problem
-84 time 12 eqauls -1008, its a negative because it has a negative in the equation
-1008= c
d *88 = -88,000 You have to divide 88 from both sides to get the d alone.
d * 88/88 = -88,000/88. And you end up with
D = -1000 d equals negative 1000

PLEASE HELP ME! Sketch a triangle and label correctly. Work must be shown for this problem. Round answers to the nearest hundredth (2 decimal places).
Answer:
We can use the trigonmetry to solve for this. So first, we need to get that cos(69) = x/16. So then we multiply by 16 and get 16cos(69). Therefore if we use that as an answer approx it gives 5.734.
Answer: 5.734 approx.

Which graph shows the line y - 2 = 2(x + 2)?
A/B/
10
D
Step-by-step explanation:
if y was 0 then
0 - 2 = 2(x+2)
-2=2x+4
-6=2x
-3
if y was 1 then
1 - 2 = 2(x+2)
-1=2x+4
-5=2x
-2.5
now if y was 2 then
2 - 2 = 2(x+2)
0 = 2x + 4
-4=2x

If you multiply 235 by 49, what will be the partial products?
Answer:
Step-by-step explanation:
(200+30+5)(40+9)
40*200 = 8000
40*30= 1200
40*5=200
9*200= 1800

What is the area of this figure?
Answer:
11610
Step-by-step explanation:
First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.
Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.
Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.
Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.

Answer:
47.5% of students fall within heights of 100 cm to 120 cm
Step-by-step explanation:
We are given that heights of Grade 1 students are normally distributed
Mean = [tex]\mu = 100 cm[/tex]
Standard deviation = [tex]\sigma = 10 cm[/tex]
a)
Empirical rule
68% of data lies within the first standard deviation from the mean i.e[tex].(\mu-\sigma , \mu+\sigma)=(100-10,100+10)=(90,110)[/tex]
95% of all the data will fall within two standard deviations i.e.[tex](\mu-2\sigma , \mu+2\sigma)=(100-2(10),100+2(10))=(80,120)[/tex]
99.7% of data lies within the three standard deviations i.e.[tex]( \mu - 3 \sigma , \mu +3 \sigma)=(100-3(10),100+3(10))=(70,130)[/tex]
b)Percentage of students fall within heights of 100 cm to 120 cm
Using the normal distribution curve
Percentage of students fall within heights of 100 cm to 120 cm = [tex]\frac{1}{2} \times 95\% = 47.5\%[/tex]
Hence 47.5% of students fall within heights of 100 cm to 120 cm

Answer:
x = 20
Step-by-step explanation:
so we aren't give the angle across from 70, but we are given the degree on the outside, so if we take that and subtract it from 180 we will get the degree inside the triangle which is 70. (this also appears to be an isosceles triangle so it would be 70 anyway, but we can do this just to make sure.) Then, since all of the angles in the triangle add up to 180, we can subtract 140 (both 70 degrees) from it and we are left with 40. Divide 40 by 2 and you will get 20 which is the measure for angle x! Hope this helps

Quadrilateral ABCD is translated up and to the right and then rotated about point Q. Which congruency statement is correct?
Answer: B
Step-by-step explanation:
The congruency statement would be correct as ABCD ≅ ZYXW because the new triangle will be congruent to the original triangle when a triangle is translated.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
Given that Quadrilateral, ABCD is translated up and to the right and then rotated about point Q.
The following are the related points from the entire question:
Point A and point Z
Point B and point Y
Point C and point X
Point D and point W
This represents that:
Points A and Z are corresponding
Points B and Y are corresponding
Points C and X are corresponding
Points D and W are corresponding
Hence, the congruency statement would be correct as ABCD ≅ ZYXW because the new triangle will be congruent to the original triangle when a triangle is translated.

2. Solve this equation to find all possible values of the angle 3x
3. Use algebra to find all values of x between 0 and 2pi that satisfy this equation
Step-by-step explanation:
cos(3x) = 1
3x = 0 + 2kπ
x = 0 + 2kπ/3
x = 0, 2π/3, 4π/3, 2π
What will happen to the graph of the line y = 3/4x – 7 if you change 3/4 to −3/4?
Answer:
Below.
Step-by-step explanation:
The slope is given by the coefficient of x (= 3/4) .
If the slope changes to -3/4 the line will slope in the opposite direction.
If the slope is 3/4(positive) it rises to the right and if it is -3/4 it will rise to the left, but will rise at the same rate.
The 2 lines will cross each other when 3/4x - 7 = -3/4x - 7:
3/4x - 7 = -3/4x - 7
6/4 x = 0
x = 0
So they will cross at the point (0, -7).
