Answer:
x > -25.
Step-by-step explanation:
-39 < 5x + 36
Subtract 36 from both sides:
-39 - 36 < 5x + 36 - 36
-75 < 5x
5x > -75
Divide both sides by 5:
x > -25.

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.
Answer:
59.04°
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°
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

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°.

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.
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.

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

In parallelogram PQRS, PQ =4x+28, QR=x+31, RS = 10X+4. Which of the
following is the length of RS ? Hint: draw a picture.*
0 1
44
32
4
Answer:
44
Step-by-step explanation:
1) we know that opposite sides of a parallelogram are congruent so
4x+28=10x+4
2) subtract 4 on both sides
4x+24=10x
3)subtract 4x on both sides
24=6x
4)divide by 6 on both sides
4=x
5)substitute for x
length of RS =10(4)+4
length of RD=44
The length of the side RS of the parallelogram PQRS is 44.
Given,
Side PQSide QRSide RSAs we know in a parallelogram, the opposite sides are parallel and equal. So, in this case, side PQ is equal to side RS.
Computation:
[tex]\begin{aligned}\text{Side RS}&=\text{Side PQ}\\10\text{X}+4&=4\text{X}+28\\10\text{X}-4\text{X}&=28-4\\6\text{X}&=24\\\text{X}&=4\end{aligned}[/tex]
When the value of X is determined to be 4.
By using the substitution method the value of X will be used in the side RS to determine the length of RS.
[tex]\begin{aligned}\text{RS}&=10\text{X}+4\\&=(10\times4)+4\\&=40+4\\&=44\end{aligned}[/tex]
Therefore, the length of RS is 44.
