Liana can see that the measure of Angle L and Angle M form a straight line. Since Liana knows that a straight line has an angle measure of 180 degrees, what is the measure (in degrees) of Angle M?
Answer:
150 degrees
Step-by-step explanation:
Let's start off by looking at what we are working with in this specific problem:
We can see that we are looking at 2 angles, angle L and angle M, that add up to a total of 180 degrees (aka a straight line)
Now that we know that, we also have to keep is mind that angle L + angle M = 180 degrees.
Now that we've got all of that out of the way, let's set up a simple algebraic equation:
angle L + angle M = 180
We also know that angle L is 30 degrees so let's add it into the equation we have just created:
30 + angle M = 180
We now know that 30 plus angle M (whatever it might be) is equal to 180 so in order to solve this problem we have to do some simple subtraction.
180 - 30 = angle M
Now we are left with:
150 degrees = angle M

Reuben would like to buy sports car that cost $35,000 today when he graduates from college in five years if the rate of information is expected to be 3% per year over the next five years how much wood Ruben expect to pay for a similar sports car in today's dollars
Answer:
$40,250Step-by-step explanation:
Amount he will pay in the next five years = Principal + Interest
Given Principal = $35,000
Simple Interest = PRT/100
R is the rate = 3%
T is the time in years = 5years
SI = 35,000 * 3 * 5/100
SI = $5,250
Amount = $35,000 + $5,250
Amount = $40,250
Ruben will have to pay $40,250 after 5years
Answer:
Reuben would pay $40574.59 in 5 years time
Step-by-step explanation:
The present value of the car, P = $35,000
Rate per year, R = 3% = 0.03 (Note that the rate is given per year and not for the whole 5 years, this means that the rate cannot be used over a period of 5 years)
Amount = P + RP = P (1 + R) = P ( 1+0.03)
Amount = 1.03P
Total time = 5 yrs
After year 1:
A = 1.03 * 35000 = $36,050
After year 2:
A = 1.03 * 36050 = $37,131.5
After year 3:
A = 1.03 * 37131.5 = $38,245.445
After year 4:
A = 1.03 * 38,245.445 = $39,392.808
After year 5:
A = 1.03 * 39,392.808 = $40574.59
Four girls and six boys are in a Spanish club. Three of the people will be chosen at random to represent the group in a photograph. What is the probability that one girl and two boys will be chosen? 40% 50% 60% 70%
Answer:50 %
Step-by-step explanation:
Given
There are 4 girls and 6 boys in a club
Probability of choosing 1 girl and 2 boys is
[tex]=\dfrac{\text{No of ways of choosing 1 girl and 2 boys }}{\text{No of ways of choosing 3 member out of 10 member}}[/tex]
No of ways of choosing 1 girl and 2 boys[tex]=^4C_1\times ^6C_2[/tex]
[tex]P=\dfrac{^4C_1\times ^6C_2}{^{10}C_3}[/tex]
[tex]P=\dfrac{4\times 15}{10\times 3\times 4}[/tex]
[tex]P=\dfrac{15}{30}=\frac{1}{2}[/tex]
i.e. [tex]50\%[/tex]
The probability that one girl and two boys will be chosen from the Spanish club is 50%.
What is the probability?Probability is used to determine the odds that an event would happen. If the event would happen with certainty, it would have a value of 1. If it is certain the event would not happen, it would have a value of 0.
The probability = number of ways of choosing 1 girl and two boys / number of ways of choosing 3 people
(4x15) / (10 x 3 x 4) = 15/30 = 1/2 = 50%

What is Straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point.
The standard form of a straight line is y=mx+c.
A slope of a line is the change in y coordinate with respect to the change in x coordinate
where m is the slope and c is the y intercept.
Here we have a straight line graph with y-intercept (0, -5)
and slope of m = 3.
The x-intercept is (5/3, 0).

Lorene plans to make several open-topped boxes in which to carry plants. She makes the boxes from rectangular sheets of cardboard from which she cuts out -12 inch squares from each corner. The length of the original piece of cardboard is 24 inch more than the width. If the volume of the box is 1740 inch , determine the dimensions of the original piece of cardboard.
Answer:
29 feet in length, 5 feet in width and 12 feet in height
Step-by-step explanation:
We have that for the volume of a quadrangular prism is:
V = l * w * h
Ie length times width times height
In this case, the height is determined by the squares that you put in each corner, taking into account that a square has all the same sides, the height is 12 inches. h = 12
they tell us that the length is 24 inches more than the width, that is, l = 24 + w
replacing we have:
1740 = (24 + w) * w * 12
1740 = 12 * w ^ 2 + 288 * w
12 * w ^ 2 + 288 * w - 1740 = 0
if we calculate the root, we have w = 5 or w = -29
only works when w = 5
Thus:
l = 24 + 5
l = 29
which means that the dimensions are:
29 feet in length, 5 feet in width and 12 feet in height
29 feet in length, 5 feet in width and 12 feet in height
The calculation is as follows;
The volume of a quadrangular prism is:
[tex]V = l \times w \times h[/tex]
The length is 24 inches more than the width,
So l = 24 + w
Now
[tex]1740 = (24 + w) \times w \times 12\\\\1740 = 12 \times w ^ 2 + 288 \times w\\\\12 \times w ^ 2 + 288 \times w - 1740 = 0[/tex]
if we calculate the root, we have w = 5 or w = -29
only works when w = 5
So,
l = 24 + 5
l = 29

The sum of the height and the radius of the base of cylinder is 34cm. If the total surface area of the cylinder is 2.992cm^3. Find radius
Answer:
Step-by-step explanation:I don't say you have to mark my ans as brainliest but my friend if it has really helped you plz don't forget to thank me...
Answer:
0.014 cm .
Step-by-step explanation:
I am assuming that it is a closed cylinder whose total surface area.
Area = 2πrh + 2πr^2
Let the radius be r and the height h, then we have the equations:
r + h = 34
2πrh + 2πr^2 = 2.992
From the first equation h = 34 - r, so substituting for h:
2πr( 34 - r) + 2πr^2 = 2.992
2πr^2 + 68πr - 2πr^2 = 2.992
68πr = 2.992
r = 2.992 / 68π
r = 0.014

Skylar and her children went into a movie theater and will buy bags of popcorn and pretzels. Each bag of popcorn costs $8 and each pretzel costs $3.25. Skylar has a total of $80 to spend on bags of popcorn and pretzels. Write an inequality that would represent the possible values for the number of bags of popcorn purchased, bb, and the number of pretzels purchased, p.P.
Answer:
[tex]8b+3.25p\leq 80[/tex]
Step-by-step explanation:
Each bag of popcorn costs $8
Each pretzel costs $3.25.
The total cost of b bags of popcorn =$8*b=$8bThe total cost of p pretzels purchased =$3.25*p=$3.25pSkylar has a total of $80 to spend on both items. This means that she can either spend less than or exactly $80.
i.e Total Cost [tex]\leq \$80[/tex]
Skylar's Total cost on popcorns and pretzels =8b+3.25p
Therefore:
[tex]8b+3.25p\leq 80[/tex]
