I need help. Find the value of each variable.
Answer:
x = 14√3
y = 7√3
Step-by-step explanation:
By applying sine rule in the given triangle,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{21}{x}[/tex]
x = [tex]\frac{42}{\sqrt{3}}[/tex]
x = 14√3
By applying cosine rule in the given triangle,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{y}{x}[/tex]
[tex]\frac{1}{2}=\frac{y}{14\sqrt{3}}[/tex]
y = 7√3
Plz help and show me how to solve these questions
since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.
p = 1/8 + 15/16
Use common denominator, which is 16:
p = 1(2)/8(2) + 15/16
p = 2/16 + 15/16
p = 17/16
17/16 is an improper fraction. If you want to use a mixed number for your answer, then:
17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)
Answer: 17/16 or 1 1/16what is 420 X 420 i'll give brainliest

what is -7 – 4 – (-6)
Answer:
-5
Step-by-step explanation:
Answer:
-7 - 4 -(-6)
-7 + - 4 - (-6)
-11 - (-6)
-11 + 6 = -5
Step-by-step explanation:
When looking at -7- 4, you can use the KCC rule, Keep, Change, Change. -7 would stay the same, but - would turn into a + and so would 4 to -4.
Now, -7 + - 4 would equal to -11. And bring down the -(-6).
When you look at two negative signs the become a positive sign, so it would now be +6.
Now, you subtract because 11 is the bigger number and you have to take it's sign, which is negative to the answer.
Therefore, your answer is -5. Hope this helps
Ella buys eggs and apples at the store.
She pays a total of $44.35.
She pays a total of $2.95 for the eggs.
She buys 6 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of apples costs.
Answer:
6.9
Step-by-step explanation:
The total payment was 44.35 and Ella bought 6 bags of apples and eggs
eggs cost 2.95 so apples cost 44.35-2.95=41.4
lets call bags "x"
so
6x=41.4 (price)
divide both by 6
x=6.9
While attending a major league baseball game, you think you can guess the
attendance within 10% of the actual value. If the announced attendance is
35,000, within what number of people would your guess have to be in order for you to support your claim?
Answer:
You would have to have guess a number larger than 31500 and smaller than 38500
Step-by-step explanation:
The answer will look something like
35000 +/- 10% (35000)
What that means is that the attendance would be smaller than 35000 or larger than 35000.
10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500
So you would have to estimate
35000 - 3500 ≤ attendance ≤35000 + 3500
31500 ≤ attendance ≤ 38500
Find the median of the data set below:
3,5,7,10,10,4,7,5,8,10,6
Answer:
7
Step-by-step explanation:
First put them in order. I got 3, 4, 5, 5, 6, 7, 7, 8, 10, 10, 10. The middle is the sixth, because (1+11)/2 is 6. So the median is 7.

[tex] \frac{5x - 2}{2} = 9[/tex]
Answer:
x = 4
Step-by-step explanation:
[tex]\frac{5x -2 }{2} = 9 \\[/tex]
Cross multiply,
5x - 2 = 9*2
5x - 2 = 18 {Add 2 to both sides}
5x = 18 +2
5x = 20 {Divide both sides by 5}
x = 20/5
x = 4

30 POINTS!!! PLEASE ANSWER!
In the figure, lines a, b, and c are parallel and m∠4=48°.
Drag and drop the correct angle measure for each angle.
42 degrees, 48 degrees, 132 degrees, 312 degrees
m∠1= ?
m∠2= ?
m∠3= ?
m∠5= ?
Lines a b and c are parallel and cut by a transversal. Angles 1 to 5 are labeled. Angle 1 is above line a to the left of the transversal. Angle 2 is below line a to the left of the transversal. Angle 3 is above line b to the right of the transversal. Angle 4 is below line b to the right of the transversal. Angle 5 is below line c to the right of the transversal.
m∠4=48°
m<1 = m∠4=48°
m<2 = 180 - 44 = 132
m<3 = m<2 = 132
m<5 = m∠4=48°

If a fair coin is tossed 6 times, what is the probability, rounded to the nearest thousandth, of getting at least 3 heads?
ANSWER IS 0.656
Answer:
Step-by-step explanation:
For each outcome there are
s!/(n!(s-n)!) combinations
where s is the number of selections and n is the number of specific outcomes
The probability of any specific outcome for 6 tosses of a coin is (1/2)^6
[(1/2)^6]*[(6!/6!)+(6!/(5!)+(6!/(4! 2!)+(6!/(3! 3!)]
(1/2)^6*(1+6+15+20)
42(1/2)^6
42(1/64)
42/64
21/32 which is 0.65625
0.656 (rounded to nearest thousandth)
Find the volume of the cylinder find volume of a cylinder with the same radius and double the height what is the volume of the cylinder
Answer:
1004.8^3
Step-by-step explanation:
to find the volume you must first get the area of the base
3.14 x 8 squared or 8^2 which will equal 200.96
then you multiply the base times height
200.96^2 x 5 = 1004.8 cubed or 1004.8^3
also be careful you don't multiply 200.96 twice because it is squared (;

Write an equation of the line shown in the graph in slope intercept form (y = mx + b). Show
your work for full credit.
(4,6)
(2, 2)
Answer:
y = 2x - 2
Step-by-step explanation:
Points on graph: (4,6) and (2, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2-6)/(2-4)
m=(-4)/(-2)
m = 2
Slope-intercept:
y - y1 = m(x - x1)
y - 6 = 2(x - 4)
y - 6 = 2x - 8
y = 2x - 2
