Step-by-step explanation:
Elise is standing on top of a 50 foot building and sees her friend, Molly. If Molly is 30 feet away from the base of the building, what is the angle of depression from Elise to Molly? Elise's eye height is 4.5 feet.
We solve using the Trigonometric function of Tangent
tan x = Opposite/ Adjacent
tan x= 50 ft/30ft
x = arc tan (50 ft/30 ft)
x = 59.036243468°
Approximately = 59.04°

Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

If m∠VBC=(3x+4)∘, what is the value of x?
Answer:
x = 29
Step-by-step explanation:
⇒ x + ( 2 x + 2 ) + ( 3 x + 4 ) = 180 ⇒ 6 + 6 = 180 ⇒ 6 x = 180 − 6= 174 ⇒ x = 174 6 = 29

Two out of 15 people surveyed were left handed. Based on the data how many people would you predict to be left handed out of 405 people?
A.15
B.27
C.810
D.54
Answer: D. 54 people
Step-by-step explanation:
Since there are a total of 405 people, you first divide 405 by 15 to get 27. Then multiply 27 by 2 considering two in 15 people are left handed, and you're left with 54 people.
200 children went on holiday. 18% of the children went to Wales. 27% of the children went to Scotland. How many more children went to Scotland than went to Wales?
Answer:
18 children
Step-by-step explanation:
The computation of the more children went to scotland is as follows:
Given that
There is 200 children
out of which 18% went to wales i.e. = 200 × 18% = 36
And, 27% went to scotland i.e. = 200 × 27% = 54
So, the more children went to scotland is
= 54 - 36
= 18 children
Of the 800 participants in a marathon 220 are running to raise money for a cause. How many participants out of 100 are running for a cause?
Answer:
27.5 /100 are running for a cause
Step-by-step explanation:
We know that 220/800 are running for a cause
Divide the top and bottom by 8 to get the fraction out of 100
220 /8 =27.5
800/8 = 100
27.5 /100 are running for a cause

Identify the equation of a line with a slope of -4 and a y-
intercept of (0, 2).
Step-by-step explanation:
We know that the formula for slope is y=mx+b, with m equaling the slope itself and b equaling the y-intercept. Since the slope is -4, we can safely say that the equation starts off as y=-4x.
The y-intercept is (0,2). This means that the x-coordinate is 0 and the y-coordinate is 2, so the y-intercept is 2. Since 2 is being added, the equation is y=-4x+2
Answer:
y=-4x+2

Step-by-step explanation:
Answer:
F
Step-by-step explanation:
To figure out if a set of angles are in a triangle, make sure they add up to 180
F) 58,70,62 58 + 70 + 62 = 190 This option is incorrect
G) 41,68,71 41 + 68 + 71 = 180 This option is correct
H) 68,60,52 68 + 60 + 52 = 180 This option is correct
J) 73,42,65 73 + 42 + 65 = 180 This option is correct
Since option F did not equal 180, F is the answer.
The circumference of a circular garden is 28 feet. Which of the following expressions best represents the radius of the garden?
A. 28π28 over pi
B. 28(π)28 times pi
C. 282π28 over 2 pi
D. 28(2π)
Answer: The answer is ACTUALLY C
Step-by-step explanation:
REMEMBER: The radius is always half of the diameter.
So the question is asking us what is the radius of a garden with a circumference of 28. In order to find HALF of that you would need to divide 28 so the answer is ( C ) not d...

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he inrceased the number of parts he usually makes?
Answer:Percent Increase n the number of parts usually made = 80%
Step-by-step explanation:
Percent Increase = (Increase / Initial Number of parts made daily) X 100/1
Initial Number of parts made daily = 45
Current number of parts ,made daily = 81
Percent Increase = 81-45/ 45 x 100
=36/45 x100/1
= 0.8 x 100
= 80%
Answer:
80 percent

The diagram shows triangle PQR.
PSR is a straight line.
size of angle PQS : size of angle SQR = 3:1
S
Work out the size of angle PSQ
Answer:
Angle PSQ is 61°
Step-by-step explanation:
In the triangle ΔPQR, we have;
m∠QPS = 65°
m∠PRQ = 43°
Line PSR is a straight line
m∠PQS : m∠SQR = 3:1
Therefore;
∠PQR = 180° - (∠QPS + ∠PRQ), by the angle sum theorem of a triangle
∴ ∠PQR = 180° - (65° + 43°) = 72°
∠PQR = 72°
∠PQR = m∠PQS + m∠SQR by angle addition postulate
m∠PQS : m∠SQR = 3:1
∴ m∠PQS = 3 × m∠SQR
∴ ∠PQR = m∠PQS + m∠SQR = 3 × m∠SQR + m∠SQR = 4 × m∠SQR
∠PQR = 4 × m∠SQR
∴ 4 × m∠SQR = ∠PQR = 72°
m∠SQR = 72°/4 = 18°
m∠PQS = 3 × m∠SQR = 3 × 18° = 54°
m∠PQS = 54°
∠PSQ = 180° - (∠QPS + ∠PQS) by the angle sum theorem
∴ ∠PSQ = 180° - (65° + 54°) = 61°
Angle ∠PSQ = 61°.
78x − 12 = 316x + 5 what is the answer pls help
Answer:
-0.0714 approx
Step-by-step explanation:
78x − 12 = 316x + 5
Bring all the like terms together
78x -316x = 5 + 12
-238x = 17
∴ x = 17 ÷ -238 = -0.0714 (rounded up to 3 significant figures)
There is a bag filled with 4 blue, 3 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of exactly 1 red?
Answer:
You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.
The probability of selecting a red marble the first time is 1313.
(This is because 4 out of 12 marbles are red and412412 reduces to 1313.
The probability of selecting a red marble the second time is 1313.
The marble selections are independent and you can multiply the two probabilities to get the following:
probability of getting 2 reds = (13)2(13)2
=19=19.
So the probability of getting two reds is 1919.
