what is the third angle of a triangle if the other two are (3x-20)° and (4x+10)°
Answers
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

The measures of the angles of a triangle are shown in the figure below. Solve for x.
(4x-16)
43°
109°
Answers
Step by step explanation:
Triangle rule states that all angles of a trundle must equal to 180 degrees. So we have two known angles, therefore we can subtract them from the 180 degree total.
180-109-43
=28
Now to solve for x we have the equation
4x-16=28
We add 16 to both sides to isolate x
4x=44
Now we divide each side by 4 to get rid of the coefficient
x=11
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?
Answers
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

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
Answers
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.
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)
Answers
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

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?
Answers
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
Annika was having fun playing poker. She needed the next two cards dealt to be diamonds so she could make a flush (five cards of the same suit). There are 15 cards left in the deck, and five are diamonds. What is the probability that the two cards dealt to Annika (without replacement) will both be diamonds?
a. 13%
b. 29%
c. 33%
d. 10%
Answers
Answer:
d. 10%
Step-by-step explanation:
1. Information to know
15 cards left in the deck, and 5 are diamond, to find the probability of the next 2 cards being diamond, one has to find the probability of the 1st card as a diamond, and then multiply it by the probability of the 2nd card being a diamond.
Remember, probability is;
[tex]\frac{favorable-outcomes}{total-outcomes}[/tex]
2. Find probability 1
favorable out comes; diamond = 5
total outcomes; total cards = 15
probability is; [tex]\frac{5}{15}[/tex]
Simplified; [tex]\frac{1}{3}[/tex]
3. Finding probability 2
If the last card drawn was a diamond then the new numbers will be
favorable outcomes; 4
total outcomes; 14
Probability is; [tex]\frac{4}{14}[/tex]
Simplified; [tex]\frac{2}{7}[/tex]
4. Total probability
Now, one has to multiply the first probability by the second probability to find the probability of the event;
[tex]\frac{1}{3} * \frac{2}{7}[/tex]
= [tex]\frac{2}{21}[/tex]
= 0.095238

Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk all together? Select all that apply. A: 12+0.25∙12 B: 12(1+0.25) C: 12∙1.25 D: 12∙0.25 E: 12+0.25
Answers
Answer:
Step-by-step explanation:
If Elena walk 12 miles, and then 0.25 that distance
0.25=1/4
12*1/4=3 miles is 1/4 of the distance
she walked in total 12+3=15 miles
choice A =12+12*1/4
Elena walked a total 12(1+0.25) distance.
What is a distance?The distance is the total movement of an object without any regard to direction.
First Elena walked 12 miles.
Then walked 0.25 or (1/4)th of 12 miles
i.e. 12 * (1/4) = 3
The total distance Elena walked is
12+3 = 15 miles or
12 + (1/4)*12 = 12(1+0.25)
Hence, 12(1+0.25) is the total distance walked by Elena.

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.
