Answer: u = 80° v = 25°
Step-by-step explanation:
(a) angles on a straight line = 180° - 130° = 50°
In isosceles triangle, both angles on each side is equal, so
180° - 50° - 50° = 80°
u = 80°
(b) u = (2v + 30°) because opposite angles of a parallelogram are equal.
u = 80°
80° = 2v + 30°
80 - 30 = 50
50° = 2v
25° = v
What is the slope of the line passing through the points (-3, 4) and (2, -1)?
Answer:
-1
Step-by-step explanation:
slope = (y_2 - y_1)/(x_2 - x_1)
slope = (-1 - 4)/(2 - (-3)) = -5/(2 + 3) = -5/5 = -1
How many distinguishable permutations can be formed from the letters in the word sassafras
In the word "SASSAFRAS", there 2520 permutations can be formed.
Permutation :A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
The order of arrangement in permutation is in linear form.
In the given word is “SASSAFRAS”. There are total 9 letters in which some letters appears several times, that is
S = 4 times.
A = 3 times.
F = 1 times.
R = 1 times.
We can the number of permutation to arrange this letter with the help of :
nPr = n! / (n - r)!
nPr = Permutation
n = Total number of objects
r = Number of objects selected
'!' = Factorial
Factorial :
Factorial (noted as “!”) is the product of all positive integers less than or equal to the number preceding the factorial sign. For example, 3! = 1 x 2 x 3 = 6.
So, nPr = 9!/(4!) (3!) (1!) (1!)
= (9×8×7×6×5×4×3×2×1)/(4×3×2×1)×(3×2×1)×(1)×(1)
= 3,62,880/ 24×6×1×1
= 3,62,880/144
= 2,520
Hence, 2520 permutations can be formed from the word 'SASSAFRAS'.

If the smaller of two numbers is one-half of the larger number and the sum of the two numbers is 75
Step-by-step explanation:
let the larger number=n
then the smaller number=½n
We conclude from the question that
n+½n=75
3/2n=75
3n=150
n=150/3=50
Therefore the larger number=50 and the smaller number=½×50=25
Prism L has length 8 cm.
Prism M has length 20 cm.
Prism M has a volume of 1875 cm3
Work out the volume of prism L.
The volume of prism L is 750 cm³
What is a prism?A prism is a three-dimensional solid, that has two identical bases, rectangular or parallelogram-shaped faces, and the same cross-section.
The formula for the volume of a prism is V=Bh,
where B = base area and h = height.
We have,
Two similar prism
Prism L:
Length = 8 cm
Prism M:
Length = 20 cm
Volume = 1875 cm³
Applying the volume formula:
V = Bh
Base area = Length x width
1875 = Length x width x height
1875 = 20 x width x height
Width x height = 1875 / 20 = 93.75 _______(1)
Since prisms are similar we can use (1) in finding the Volume of prism L.
The volume of prism L:
= Length x width x height
= 8 x 93.75
= 750

of the line determine by the equation 4x- 3y=-6
{(0,2),(1,3),(4,7),(6,10)}
The points in the brackets are on the graph are (0, 2) and (6, 10)
How to determine if the points in the brackets are on the graph?The equation of the line is given as
4x - 3y = -6
The points are given as:
{(0,2),(1,3),(4,7),(6,10)}
Rewrite as
(x, y) = {(0,2),(1,3),(4,7),(6,10)}
Next, we substitute the x and y values in the equation 4x - 3y = -6
So, we have
(0, 2):
4(0) - 3(2) = -6
-6 = -6 ---- true
(1, 3):
4(1) - 3(3) = -6
-5 = -6 ---- false
(4, 7):
4(4) - 3(7) = -6
-5 = -6 ---- false
(6, 10):

The only measure of center that can be found for both quantitative and qualitative data is the mode.
What is the mode?The measure of mode can be calculated for both quantitative and qualitative data. When it is unique, the mode is the value that appears the most frequently in a data set, and it, like the median and mean, can be used as a measure of central tendency. However, there are times when there is no mode or when there are multiple modes. When all observed values appear the same number of times in a data set, there is no mode. To find the mode, arrange the numbers (this makes counting easier), then count how many of each number there are. A mode is a number that appears frequently.Therefore, the only measure of center that can be found for both quantitative and qualitative data is the mode.

2|x|-9 translate 6 units up
The translation of the function 2 | x | - 9 when translated 6 units up gives the function as 2 | x | - 3.
We are given a function:
2 | x | - 9.
A function from a set X to a set Y assigns to each element of X exactly one element of Y.
We are asked to translate the function 6 units up.
This means that we have to add 6 units to the function.
A function has been “translated” when it has been moved in a way that does not change its shape or rotate it in any way.
So, we get that:
f(x) = 2 | x | - 9 + 6
f(x) = 2 | x | - 3
Therefore, the translation of the function 2 | x | - 9 when translated 6 units up gives the function as 2 | x | - 3.

The number is??
The unknown number is 8.
Let the unknown number be x.
According to the given question.
We have a phrase "Triple a number decreased by 25 is equivalent to five less than half the same number".
Therefore, the equation for the phrase "Triple a number decreased by 25 is equivalent to five less than half the same number" is given by
3x - 25 = x/2 - 5
To find the unknown number we have to solve the above equation for x.
Therefore,
3x - 25 = x - 10/2
⇒ 6x - 50 = x - 10
⇒ 6x - x = -10 + 50
⇒ 5x = 40
⇒ x = 40/5

The students at Woodward elementary voted for a school mascot. The falcon won the race 5/8 of the votes and the eagle came seconds with 1/3 of the remaining votes. Is 536 students voted for a mascot, how many students voted for the eagle
It is found that total 67 students voted for eagle.
Two ratios are set to be equal in an equation called a proportion.
Given students at Woodward elementary voted for a school mascot.
Falcon received 5/8 of the vote, winning the post.
Eagle turned up second with 1/3 of the remaining votes.
Total number of students voted for a mascot = 536
The total amount of votes falcon received = 5/8 × 536
= 67 × 5
= 335 votes
Subtract the votes received by falcon from the total number of votes.
= 536 ₋ 335
= 201
Now the remaining votes are 201, from the remaining votes eagle received 1/3 of it.
votes gained by eagle = 1/3 × 201
= 67
Therefore 67 students voted for the eagle.

By observation or by inspection, 7.40 appears the most, thus mode.
What Is the Mode?The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.
Data can be disseminated in statistics in a number of different ways. The traditional normal (bell-curve) distribution is the one that is referenced the most. The midpoint of this distribution, as well as some others, coincides with the peak frequency of observed values and is where the mean (average) value is located.
The mean, median, and mode all have the same values for such a distribution. This indicates that this value—the one that appears the most frequently in the data—is the average value, the middle value, and the mode.
When analyzing categorical data, such as automobile models or soda taste varieties, where a mathematical average median value based on ordering cannot be computed, mode is most helpful as a gauge of central tendency.

With 70% off the regular price, a dishwasher, regularly priced at $519.89, will be $155.97 only. The answer is C.
Discount is the deduction in the price of a good or service. When this reduced price is expressed in percentage then we call it a discount rate.
If the discount is given in percent, then the amount of discount can be found by using the formula:
Amount of Discount = Regular Price × Rate of Discount
If the regular price of a dishwasher is $519.89, and the discount rate is 70%, using the formula, solve for the discount value.
Amount of Discount = $519.89 x 70%
Amount of Discount = $519.89 × 0.70
Amount of Discount = $363.92
To get the final price of the dishwasher, subtract the discount value from the original or regular price.
price = $519.89 - $363.92
price = $155.97
