Find the missing lengths of the sides.
Answer:
a is 3
and b is 5
please add me as buddy
Answer:
a = 3 inches
b = 3[tex]\sqrt{3}[/tex] inches
Step-by-step explanation:
From the figure,
Sin 30° = Opposite / Hypotenuse
Sin 30° = a / 6
1 / 2 = a / 6 (Sin 30° = 1/2)
a = 3 inches
From the same angle,
Cos 30° = Adjacent / Hypotenuse
Cos 30° = b / 6
[tex]\frac{\sqrt{3} }{2}[/tex] = [tex]\frac{b}{6}[/tex] (Cos 30° = [tex]\sqrt{3}[/tex] / 2)
b = 6 * [tex]\frac{\sqrt{3} }{2}[/tex]
b = 3[tex]\sqrt{3}[/tex] inches

)A scanner scanned 63 photos in 9 minutes. If it scans photos at a constant rate, it can scan _____ photos in 21 minutes.
Answer:
147 photos
Step-by-step explanation:
63 photos -> 9 minutes
To find the number of photos scanned per minute, divide both sides by 9.
[tex]63\div 9=7[/tex] photos -> 1 minute
To find 21 minutes, we can do [tex]21\times 7=147[/tex]

An object is traveling in a steady speed of 10 1/5 mi/h. How long will it take the object to travel 4 4/5 mi? First round to the nearest integer. Then find the exact answer.
Answer:
30
Step-by-step explanation:
Speed is the rate of change of distance over time
It will take the object 28 minutes to travel a distance of [tex]\mathbf{4 \frac 45 miles}[/tex]
The given parameters are:
[tex]\mathbf{Speed = 10 \frac 15 mi/h}[/tex]
[tex]\mathbf{Distance = 4 \frac 45 mi}[/tex]
The speed of an object is:
[tex]\mathbf{Speed = \frac{Distance}{Time}}[/tex]
Make Time the subject
[tex]\mathbf{Time= \frac{Distance}{Speed }}[/tex]
Substitute known values
[tex]\mathbf{Time = 4 \frac 45 mi \div 10\frac 15 mi/h}[/tex]
Cancel out the units
[tex]\mathbf{Time = 4 \frac 45 \div 10\frac 15 \ h}[/tex]
Convert fractions
[tex]\mathbf{Time = \frac {24}5 \div \frac{51}5 \ h}[/tex]
Express as multiplication
[tex]\mathbf{Time = \frac {24}5 \times \frac{5}{51} \ h}[/tex]
[tex]\mathbf{Time = \frac {24}{51} \ h}[/tex]
Convert to minutes
[tex]\mathbf{Time = \frac {24}{51} \times 60\ min}[/tex]
[tex]\mathbf{Time = \frac {1440}{51} \ min}[/tex]
[tex]\mathbf{Time = 28 min}[/tex]
Hence, it will take the object 28 minutes

Given: △ABC, CM⊥ AB, BC = 5, AB = 7
CA = 4 sqrt(2)
Find: CM
Answer:
The general plan is to find BM and from that CM. You need 2 equations to do that.
Step One
Set up the two equations.
(7 - BM)^2 + CM^2 = (4*sqrt(2) ) ^ 2 = 32
BM^2 + CM^2 = 5^2 = 25
Step Two
Subtract the two equations.
(7 - BM)^2 + CM^2 = 32
BM^2 + CM^2 = 25
(7 - BM)^2 - BM^2 = 7 (3)
Step three
Expand the left side of the new equation labeled (3)
49 - 14BM + BM^2 - BM^2 = 7
Step 4
Simplify And Solve
49 - 14BM = 7 Subtract 49 from both sides.
-49 - 14BM = 7 - 49
- 14BM = - 42 Divide by - 14
BM = -42 / - 14
BM = 3
Step Five
Find CM
CM^2 + BM^2 = 5^2
CM^2 + 3^2 = 5^2 Subtract 3^2 from both sides.
CM^2 = 25 - 9
CM^2 = 16 Take the square root of both sides.
sqrt(CM^2) = sqrt(16)
CM = 4 < Answer

A while ago, Nicole bought shares of stock in a high-tech firm. At that time, the selling price was $60 per share. According to today's newspaper, a share is currently worth 30% more. What is the current value of one share?
Answer:
Step-by-step explanation:
1. Dividends
2. Capital gains
-The discounted present value of the sum of next period's dividend plus next period's stock price
-The discounted present value of all future dividends
P0 = [(Div1)/(1+R)] + [P1/(1+R)]
where Div 1 = expected dividend paid at year's end
P1 = expected price at year's end
R = discount rate
Answer:
$78
Step-by-step explanation:
A share is worth 30% more, so multiply 30% by 60 to get 30% of 60, which is 18. Then, add 18 to 60 because the share is 30% more, and you get 78.

Answer:
[tex]5x^6[/tex]
Step-by-step explanation:
Answer:
[tex] 5x^6(3x^3 + 5x^2 + 11) [/tex]
Step-by-step explanation:
The GCF of 15, 25, and 55 is 5.
The GCF of x^9, x^8, and x^6 is x^6.
The GCF of the terms of the polynomial is 5x^6.
Now we factor it out of the polynomial by dividing each term of the polynomial by the GCF of the polynomial.

Find the value that completes the ordered pair to describe the transformation of f(x) to g (x).
If (x, y) is a point on f(x), then
(x +
3
, y +
1
) is a point on g(x).
Answer:
we know that if: (x, y) is a point of f(x):
This means that f(x) = y.
Then (x + 3, y + 1) is a point of g(x)
This means that:
g(x + 3) = y + 1
Then we have two shifts.
For a real and positive number A.
A horizontal shift of A units to the right can be written as:
f(x - A)
A vertical shift of A units up can be written as:
f(x) + A.
Then in this case we have:
An horiozontal shift of 3 units to the right, and a vertical shift of 1 unit up, this means that:
g(x') = f(x' - 3) + 1.
then evaluating this at x' = x + 3
g(x + 3) = f(x + 3 - 3) + 1 = f(x) + 1 = y + 1
That is what we had initially.
Answer:
(x + 2, y + -2) is a point on g(x).

Use the Law of Cosines to determine the indicated angle 0. (Assume a - 139.5, b = 59.5, and c = 156.5. Round your answer to the nearest degree.)
====================================================
Work Shown:
Law of cosines
c^2 = a^2 + b^2 - 2*a*b*cos(C)
156.5^2 = 139.5^2 + 59.5^2 - 2*139.5*59.5*cos(C)
24492.25 = 19460.25 + 3540.25 - 16600.5*cos(C)
24492.25 = 23000.5 - 16600.5*cos(C)
24492.25 - 23000.5 = -16600.5*cos(C)
1491.75 = -16600.5*cos(C)
-16600.5*cos(C) = 1491.75
cos(C) = (1491.75)/(-16600.5)
cos(C) = -0.0898617511520737
C = arccos(-0.0898617511520737)
C = 95.1556537886261
C = 95 degrees approximately
Make sure your calculator is in degree mode.
"arccos" is short for "arccosine" which is the same as inverse cosine. Your calculator may show this as the button labeled [tex]\cos^{-1}[/tex]

During the regular season, a National Basketball Association team plays 82 games and a National Football League team plays 16 games. In simplest form, what is the ratio of NFL regular season games to NBA regular season games?
Answer:
NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the monthly demand for widgets. WidgCo's marketing department determines that p and x are related by the following demand equation: p(x) = 211 − 5x. The cost of producing x widgets is given by C(x) = 1,401 + 16x. Construct the revenue function, R(x). Find the production level that will result in the maximum revenue. Find the maximum monthly revenue. Enter your answer to part c in the box below. Round your answer to the nearest cent.
Answer:
the revenue function = x · P(x) - C(x) = x · (211 − 5x) - (1,401 + 16x) = 211x - 5x² - 1,401 - 16x = -5x² + 211x - 16x - 1,401
R(x) = -5x² + 195x - 1,401
maximum revenue will be obtained for R'(x)
R'(x) = 2 · -5x + 195 = -10x + 195 = 0
195 = 10x
x = 19.5
the production level that yields a maximum profit should be 19.5
maximum monthly revenue
R(x) = -5·19.5² + 195·19.5 - 1,401 = -1,901.25 + 3,802.50 - 1,401 = $500.25
