One angle of an isosceles triangle measures 132º. Which other angles could be in that
isosceles triangle? Choose all that apply.
An isosceles triangle is a triangle that has two sides and thus two angles the same amount. Triangles have 180 degrees, so if we subtract:
180 - 132 = 48, we do not have enough degrees to have a second 132° angle That leaves the 48° to be the angles to be split:
48 / 2 = 24°
So your answer is going to be 130-25-25 angle triangle.
*Just for reference, an example of an isosceles triangle having two possible answers? Let's say the given degree is 50o. Thus it could be one of the mirrored degrees (80-50-50), or it could be the non-mirrored angle (50-65-65)
Answer:
The other two angles of isosceles triangle will be 24° each.
Step-by-step explanation:
An isosceles triangleAn isosceles triangle is a triangle that has two sides and thus two angles opposite to the equal sides will be same .
Also Triangles have sum of all angle to be 180° , so if we subtract the given angle we get
180° - 132° = 48°,
So the total sum of angle remaining for other two angles will be of 48°
Therefore the sum of each angle will be
48° / 2 = 24°
So all angles of the isosceles triangle will be 132°-24°-24°angle triangle.

A sphere fits inside a cube with the sphere's diameter equal to the width of the cube, 20 centimeters. What is the volume of the cube not filled by the sphere? Round to the nearest cm³
A) 3813cm³
B) 3225cm³
C) 4079cm³
D) 3546cm³
The volume of the cube not filled by the sphere is 3811.209. Option A is the correct.
What is volume?The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic m.
The volume of sphere is found as;;
[tex]\rm V_{sphere}= \frac{4}{3} \pi r^3 \\\\ V_{sphere}= \frac{4}{3} \times 3.14 (10)^3 \\\\ V_{sphere}= 4188.79 \ cm^3[/tex]
The volume of cube is found as;
Volume of cube = Length x width x height
Volume of cube =20 x 20 x 20
Volume of cube = 8000
The volume of the cube not filled by the sphere is found by subtract the volume of the cube by the volume of the sphere.
V=8000 - 4188.790205
V = 3811.209
The volume of the cube not filled by the sphere is 3811.209.
Hence, option A is the correct.

Find the values of x and y
Answer:
x = 54, y = 63
Step-by-step explanation:
117° and the left base angle are adjacent and sum to 180°
base + 117° = 180° ( subtract 117° from both sides )
base = 63°
Since the triangle is isosceles ( congruent legs ) then the 2 base angles are congruent , so y = 63
and x = 180 - (63 + 63) ← sum of angles in a triangle
x = 180 - 126 = 54

Sallie makes candles using different scents. She sells each candle for $8 on her website. She writes the equation y = 8x to determine how much money, y, she earns from selling x candles. What does the independent variable represent in this situation? A The number of scents B The number of candles Sallie sells C The cost of each candle Sallie sells D The total amount of money Sallie earns selling candles
Answer:
B The number of candles Sallie sells
Step-by-step explanation:
Given the equation :
y = 8x
y = amount earned ; x = number of candles sold
Cost per candle = 8
The Independent variable is the number of candles sallie sells as it is this variable which determines the amount which sallie will earn from candle sales (dependent variable). In essence, the variable which determines or affects the dependent variable is the independent variable.

B
The image of the straight lines is missing so i have attached it.
Answer:
x = 20°
y = 120°
Step-by-step explanation:
From the image attached, we can say that;
3x + (7x - 20) = 180
This is because sum of angles on a straight line is 180°
Thus;
3x + 7x - 20 = 180
10x = 180 + 20
10x = 200
x = 200/10
x = 20°
Also,3x + y = 180
Because sum of angles on a straight line is 180°. Thus;
3(20) + y = 180
60 + y = 180
y = 180 - 60
y = 120°

I have around 40 minutes so its not too much of a rush, Thank you! :)
Answer:
P(number greater than 4) = 1/6(50)
In numbers 1 to 6 only 5 and 6 are greater than 4.
Hence, the probability that she will get a number greater than 4 is 2 out of 6 or 2/6.
________________________________
The probability that she'll get more than 4 if she throws the dice 50 times–
The probability that she'll get more than 4 if she throws the dice 50 times–= 50 × 2/6________________________________

Answer:
y = 5√3
x = 10√3
Step-by-step explanation:
From the given sides
Adjacent = 15
Opposite = y
Hypotenuse = x
Angle of depression = 30degree
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 30 = y/15
y = 15tan30
y = 15(1/√3)
y = 15√3/3
y = 5√3
Similarly
cos theta = adj/hyp
cos 30 = 15/x
x = 15/cos30
x = 15 /√3/2
x = 30/√3
x = 30√3/3
x = 10√3

A drug company conducts trials of a new vaccine for a rare but usually fatal disease. The company creates a
geometric model for this trial and establishes p=0.2 as the probability of success.
What can be said about this model?
Select all that apply.
1)The company predicts 4 failures before a success.
2)Each trial is independent.
3)The probability is the same for each trial.
4)The probability that the vaccine will be effective is p = 0.8.
5)Success is defined as preventing the disease.
6)The company predicts 8 failures before a success.
7)Success is defined as p = 0.2.
Answer:
What can be said about the model are;
1) The company predicts 4 failures before success
2) Each trial is independent
3) The probability is the same for each trial
4) Success is defined as preventing the disease
Step-by-step explanation:
The probability of success for the vaccine, p = 0.2
Therefore, the probability that the vaccine is effective and prevents the disease = 0.2
A geometric distribution probability of success is given by the following formula;
P(X = x) = p × q⁽ˣ⁻¹⁾
The expected value, E(Y) = 1/p
The number of failures before success, E(Y) = (1 - p)/p = (1 - 0.2)/0.2 = 4
Where;
q = The probability of a trial failing = 1 - p = 1 - 0.2 = 0.8
q = 1 - p
∴ The e
The geometric model criteria are;
a) Each trial can only have one of two outcomes success or failure
b) The probability of success for each trial is fixed
c) The geometric distribution is concerned with finding how many trials are required to get one success
d) The trials are independent
Therefore, we have;
The number of failures the company predicts before a success = 4 failures
2) The trials are independent
3) Each trial has an equal probability
4) Success is defined by the effectiveness of the vaccine in the prevention of the disease

What is the distance between the two points 5,3 and (1,0)?
Answer: The distance between (5,3),(1,0) is 25units square.
Step-by-step explanation:
So, I usually plot the points, and conect them first.
And then I draw a right triangle, so draw two line that conect to the line that we need to find the distance, and form a triangle. Make sure that the line from point (5,3)(1,0) is the Pythagorean triples.
Next, you count the units of the two line that makes a right angle. which is 4 units for the first line, and 3 units for the second.
Thirdly, you plug the numbers into the Pythagorean equation, which is a^2+b^2=c^2 (plug it into a and b, it doesn't matter which number for which letter)
4^2+3^2=c^2
16+9=c^2
25=c^2
[tex]\sqrt{25}[/tex] = [tex]\sqrt{c}[/tex]
c=25

There are 6 red marbles 4 blue marbles to yellow marbles. Sabrina picks 2 marbles without putting the first one back what is the probability that she picks a not yellow marble and then a blue marble.
Answer:
P = 3/11
Step-by-step explanation:
There are:
6 red marbles
4 blue marbles
2 yellow marbles.
So there are a total of 12 marbles in the bag, such that each one has the same probability of being randomly picked.
We want to find the probability that the first pick is not yellow (so it can be either blue or red), and the second pick is a blue marble.
Now there are two cases.
The first marble is red and the second blue
the first marble is blue and the second blue
We need to find the probability in each case.
The probability that the first marble is red is equal to the quotient between the number of red marbles (6) and the total number of marbles (12)
p = 6/12
Now, for the second draw, we need a blue marble, the probability in this case is the quotient between the number of blue marbles (4) and the total number of marbles in the bag (now there are 11, because one is already taken)
q = 4/11
The joint probability is equal to the product of the individual probabilities, then:
P₁ = p*q = (6/12)*(4/11) = 2/11
And for the other case, we draw two blue marbles:
For the first draw, the probability is:
p = 4/12
And for the second draw, now there are 3 blue marbles and 11 total marbles, then the probability is:
q = 3/11
The joint probability is:
P₂ = (4/12)*(3/11) = 1/11
The total probability is then:
P = P₁ + P₂ = 2/11 + 1/11 = 3/11
