what is the third angle of a triangle if the other two are (3x-20)° and (4x+10)°
Answer:
The other angle is 190-7x.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Let A be the third angle.
A + (3x-20) + (4x+10) = 180
A = 180 - (3x - 20) - (4x + 10) = 190 - 7x

Answer: 0.12
Step-by-step explanation:
The expected number of accidents is a weighted average of the potential number of accidents and their probabilities:
= (0 * 0.935) + (1 * 0.03) + (2 * 0.02) + (3 * 0.01) + (4 * 0.005)
= 0.12
0% of the students on a field trip love the museum. If there are 0 students on the field trip, how many love the museum?
Answer:
0 students love the museum
Step-by-step explanation:
since the percentage of students that love the museum is zero, no matter how many students went, the number of people who like the museum will always be 0
now if 100 students went and 32% loved the field trip, then you would take 32% of the amount of students who went, to find the exact number of students who liked the field trip
32% of 100 is 32, so in my example, 32 people loved the museum
Four expressions are shown:
A. 10x + 6
B. 12x + 4
C. 2(5x + 3)
D. 2(6x + 2)
Which two expressions are equivalent to 2(5x + 2 + x)? (1 point)
A and C
B and D
A and D
B and C
Answer:
B and D
Step-by-step explanation:
Simplify the given expression as shown below:
2(5x+2+x)= 2(6x+2) = D
Also
2(6x+2) = (2×6x) + (2×2)= 12x + 4 = B
Hence Both B and D are equivalent to 2(5x+2+x)

A rocket is shot straight into the air at an initial velocity of 70 feet/second.
The height of the rocket after t seconds is represented by the formula
h = 70t - 5tº. What is the maximum height the rocket reaches?
235 feet
265 feet
215 feet
245 feet
Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:
[tex]h=70t-5t^2[/tex]
[tex]\dfrac{dh}{dt}=70-10t[/tex] [Differentiate both sides w.r.t. t]
Put
[tex]\dfrac{dh}{dt}=0\\\\\Rightarrow\ 70-10t=0\\\\\Rightarrow\ t=\dfrac{70}{10}=7[/tex]
Also, [tex]\dfrac{d^2h}{dt^2}=-10<0[/tex] i.e. height is maximum at t=7.
Maximum height = [tex]h=70(7)-5(7)^2 = 490 - 245= 245\text{ feet}[/tex]
Hence, the maximum height the rocket reaches = 245 feet.

i got a 30 degrees because its a straight line and 180-150=30
and same for 40 degrees
and 110 because its a triangle so inner angles have to add up to 180 so 180-(40+30)

We assume you want factors that use real integers.
a) 121x² +36y² . . . . cannot be factored using real numbers
b) (4x +4)(x +1) = 4(x +1)²
c) x(x² -4) = x(x -2)(x +2)

Emilia conducted an experiment with Growing crystals. At the beginning of the experiment, she had a crystal that measured 6MM. She recorded the length every hour and notice that it increased by 12MM every hour. Emilia Task to the relationship between time and length of the crystal. Which towo ordered pairs are on Emilia's graph? (1,12) (2,30) (4,36) (5,66) (7,54)
Answer: (2,30), (5,66)
Step-by-step explanation: I truly don’t know if this is correct, but at the beginning, the crystal was already 6 mm. She then realized it increased 12 mm every hour, so if one hour passed, it would be 12+6= 18. Okay, so now that we know that, we multiple the hours by 12 and then add the 6.
12x2= 24
24+ 6= 30,
12x5= 60
60+6= 66

Students majoring in psychology surveyed 200 of their fellow students about their dreams. The results of the survey are shown in the Venn diagram. Let B be the event that the participant dreams in black and white and let C be the event that the participant dreams in color.
What is the probability that a randomly selected participant dreams in black and white or color?
Answer:
0.13
Step-by-step explanation:
4/200=0.02 12/200=0.06 10/200=0.05
0/02+0.06+0.05=0.13
The probability that a randomly selected participant dreams in black and white or color is 0.13.
What is probability ?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Math to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. "
Probability of all black = 4/200=0.02
Probability of all white = 12/200=0.06
Probability of all other color = 10/200=0.05
So, probability that a randomly selected participant dreams in black and white or color =0.02+0.06+0.05=0.13
Hence, the probability that a randomly selected participant dreams in black and white or color = 0.13

Right triangle EFG and right triangle EHG overlap as shown below. Angle HEG measures 35° and angle FGE measures 30°.
What are the values of x and y?
Given:
Triangle EFG and EHG are two right triangles.
[tex]m\angle HEG=35^\circ[/tex]
[tex]m\angle FGE=30^\circ[/tex]
To find:
The values of x and y.
Solution:
In triangle EFG,
[tex]m\angle EFG+m\angle FGE+m\angle FEG=180^\circ[/tex] [Angle sum property]
[tex]90^\circ+30^\circ+(x+35)^\circ=180^\circ[/tex]
[tex](x+155)^\circ=180^\circ[/tex]
[tex]x+155=180[/tex]
[tex]x=180-155[/tex]
[tex]x=25[/tex]
In triangle EHG,
[tex]m\angle EHG+m\angle HEG+m\angle EGH=180^\circ[/tex] [Angle sum property]
[tex]90^\circ+35^\circ+(y+30)^\circ=180^\circ[/tex]
[tex](y+155)^\circ=180^\circ[/tex]
[tex]y+155=180[/tex]
[tex]y=180-155[/tex]
[tex]y=25[/tex]
Therefore, the value of x is 25 and the value of y is also 25.

a pile of coins, consisting of quarters and half dollars is worth $11.75. If there are 2 more quarters than half dollars, how many of each are there?
Answer:
Hope it helps ..and ☆HAPPY New year MY DEAR ☆
Step-by-step explanation:
Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dolla
17 quarters, 15 half dollars
