In triangle ABC, the measure of angle A is , the measure of angle B is , and the measure of angle C is . What is the combined measure of the three angles?
Answers
The combined measure of the three angles in triangle ABC is angle A + angle B + angle C degrees.
Explanation:The combined measure of the three angles in triangle ABC can be found by summing the measures of angle A, angle B, and angle C.
So, the combined measure of the three angles is angle A + angle B + angle C = angle A + angle B + angle C degrees.
For example, if angle A = 40 degrees, angle B = 60 degrees, and angle C = 80 degrees, then the combined measure of the three angles would be:
40 + 60 + 80 = 180 degrees.

Which number is not in scientific notation? 11 ⋅ 1021 5.7 ⋅ 109 3.1 ⋅ 10−12 1.67 ⋅ 10−5
Answers
Scientific notation requires that the digits part is greater than zero and less than 10 (it cannot be 10).
So, to put that number in scientific notation 11 must be converted to 1.1*10 and 11 * 10^21 is 1.1 * 10 * 10^21 = 1.1 * 10^22.
Note tha 11 * 10^21 is the same that 1.1 * 10^22 but the last is in scientific notation while the former is not.
All the other numbers have the digit part in the range [1,10), so they are in scientific notation.

A bag contains 20 marbles of the same size that are blue, green, and red. The probability of picking a blue marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a red marble from the bag and then classify the probability of picking a red marble as likely or not likely to occur.
Answers
Hello!!
This is the correct answer.
Probability (Blue Marble) = 20%
Probability (Green Marble) = 50%
Probability (Red Marble) = ?
20% - 50% = 30%
The probability of picking a red marble from the bag is 30%.
Likely is defined as 50% so in this case, the probability of picking a red marble is not likely.

A student answers
90%
of the questions on a math exam correctly. If
sheshe
answers
27
questions correctly, how many questions are on the exam?
Answers
To find the number of questions in the exam, make an equation
(90% = [tex] \frac{90}{100} [/tex] = 0.9)
[tex] \frac{90}{100} [/tex] = [tex] \frac{27}{x} [/tex]
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
[tex] \frac{90x}{90} = \frac{2700}{90} [/tex]
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.
To find the total number of questions on the exam, set up a proportion 27 / x = 90% / 100%. Solve for x to find that there are 30 questions on the exam.
Explanation:To find the total number of questions on the exam, we can set up a proportion. Let's represent the total number of questions on the exam as x.
The proportion would be:
Correctly Answered Questions / Total Questions = Percentage Correct
Substituting the given values:
27 / x = 90% / 100%
Cross multiplying:
27 * 100% = x * 90%
27 = 0.9x
Dividing both sides by 0.9:
x = 27 / 0.9
x = 30
Therefore, there are 30 questions on the exam.
Find an equation of the line that has a y-intercept of -2 and is perpendicular to the graph of 3x+6y=2
Answers
First move the 3x over to get
6y= -3x + 2
Now solve for y by divided by 6
Y= -3/6x + 2/6
A line perpendicular to this equation would have a slope that is the opposite reciprocal, so flip the -3/6 and change the sign
This gives u 6/3 which simplifies to two
The new equation of the line would be y= 2x - 2
Find the value of x so that the function has the given value.
h(x)=−7x ; h(x)=63
Answers
you get this by dividing 63/-7
The value of x for which the function h(x) = - 7x is h(x) = 63 is - 9.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, h(x) = -7x and h(x) = 63.
∴ We can equate these two functions as h(x) = h(x) which is,
- 7x = 63.
- x = 63/7.
- x = 9.
x = - 9.

A bucket holds c liters of water, but a jar holds 8 liters less. How many times as much water can the bucket hold as the jar?
Answers
The ratio representing how many times as much water the bucket can hold as the jar is [tex]\frac{c}{c-8}[/tex], where c is the capacity of the bucket in liters.
If a bucket holds c liters of water and a jar holds 8 liters less than the bucket, then the jar holds c - 8 liters of water. To find how many times as much water the bucket can hold as the jar, we divide the bucket's capacity by the jar's capacity. This gives us the ratio of the bucket's capacity to the jar's capacity, which is [tex]\frac{c}{c-8}[/tex].

A right rectangular prism is 5 inches long, 12 inches wide, and 8 inches tall. The diagonal of the base is 13 inches.
The area of the cross section that is perpendicular to the base and created by a plane that slices the prism through the diagonals of the base and its opposite face is _ ?
square inches.
Answers
Answer:
Area of cross section is 104 [tex]\:inche^2[/tex]
Step-by-step explanation:
Given Dimensions of Rectangular prism are Length = 5 inches, Width = 12 inches and Height = 8 inches.
The shape of the cross section that is perpendicular to the base and created by slicing the prism through diagonals of top and bottom is Rectangle.
Length of rectangle = Length of diagonal of base & top = 13 inches
Width of Rectangle = Height of Prism = 8 inches
Area of Cross Sectional Rectangle = Length × Width
= 13 × 8
= 104 [tex]\:inche^2[/tex]
Therefore, Area of cross section is 104 [tex]\:inche^2[/tex]

Since percentages are often thought of as parts of a larger whole thing, there can a tendency to divide instead of multiply when faced with a problem such as "find 35% of 80." As the example below shows, after converting the percent to a decimal, the next step is to multiply, not divide.

You start out driving from your house to an old friend’s house in a different town, which is 280 miles away. After an hour and a half, you have gone 105 miles.
a) Assuming your speed is constant, find a linear function , which gives the distance from your house (in miles) as a function of time (in hours).
b) Find and interpret D(1).
c) Solve D(t)=280
d) Solve D(t)^3>=140 and interpret the result.
e) Considering the context of this function, what is the domain?
f) What is the range?
Answers
Given that after an hour and a half, you have gone 105 miles and that your speed is constant, this means that the slope which represents the speed with which you are driving is given by
[tex] \frac{105}{1.5} =70 \ miles \ per \ hour[/tex]
At 0 hours, he has travelled 0 miles.
The equation of a straight line is given by y = mx + c, where m represent the slope and c is the y-intercept (the value of y when x is 0).
Therefore, a linear function , which gives the distance from the house (in miles) as a function of time (in hours) is given by D = 70t.
Part B:
D(1) is the value of D when t = 1.
D(1) = 70(1) = 70
This means that the distance traveled after 1 hour is 70 miles.
Part C:
D(t) = 280 means the time it takes you to travel 280 miles.
70t = 280
t = 280 / 70 = 4
t = 4.
Part D:
[tex]D(t)^3 \geq 140 \\ \\ \Rightarrow 70t^3 \geq 140 \\ \\ \Rightarrow t^3 \geq \frac{140}{70} =2 \\ \\ \Rightarrow t \geq \sqrt[3]{2} [/tex]
Part E:
The domain is a set of the possible values of the independent variable, from the context of the function, the independent variable is the time it took him for the journey.
Therefore, the domain of the function is [0, 4].
Part F:
The range is the set of the possible values of y, y in the context of the question is the distance travelled at each particular time.
Therefore, the range of the function is [0, 280].

Marlene rides her bicycle to her friend Jon's house and returns home by the same route. Marlene rides her bike at constant speeds of 6 mph on level ground, 4 mph when going uphill and 12 mph when going downhill. If her total time riding was 2 hours, how far is it to Jon's house?
Answers
x = level ground
y = hills
x/6 +y/4 +y/12 + x/6 = 2 hours
multiply everything by 12 to get rid of the denominators:
equation becomes 2x +3y +y +2x = 24
combine like terms:
4x +4y = 24
divide everything by 4
f +h = 6 miles to Jon's house
Jon's house is 6 miles further away from Marlene's house.
Given that:
Speed on level ground is 6 mph
Speed on uphills is 4 mph
Speed on downhills is 12 mph
Let there are x miles level ground and y miles hills(either up or low, which while returning to home will serve as low or up respectively) in the route, then the whole route's length is x + y miles.
Since time taken = distance/speed , thus we have:
[tex]2 = \dfrac{x}{6} + \dfrac{y}{4} + \dfrac{x}{6} + \dfrac{y}{12}\\\\\text{Multiplying 12 on both sides}\\\\24 = 4x + 4y\\6 = x + y[/tex]
Since x + y denotes the length of the whole route(one sided), thus, Jon's house is 6 miles further away from Marlene's house.
