Finding the measure of the angle indicated
Answer:
30
Step-by-step explanation:
the sum of the three angles in a triangle is 180
so we have,
70+70+x=180
140+x=180
x=180-140=40
now, find the sum of 40 and 63
it is 103
subtract,
180-103=77
add,
77+73=150
180-150=30
30

Answer:
34
Step-by-step explanation:
73 + 73 = 146
180 - 146 = 34

Mrs. Juarez graded ten English papers and recorded the scores.
92, 95, 100, 62, 88, 90, 100, 96, 89, 98
Which statements are true? Check all that apply.
The range of scores is 38.
Without the outlier, the range of scores would be 12.
The outlier impacts the range more than it impacts the interquartile range.
The interquartile range is 9.
The interquartile range is 4.
Without the outlier, the interquartile range would be 9.5.
Answer:
THE ONLY STATEMENT THAT IS FALSE IS THE NUMBER 5.
Step-by-step explanation:
Table of ordered data
number of value
data
1 62
2 88
3 89
4 90
5 92
6 95
7 96
8 98
9 100
10 100
Range of scores: 100 - 62 = 38
Oulier: 62 => Range without the outlier = 100 - 88 = 12
Interquartile range, IQR, = difference between third quartile and first quartile: IQR = Q3 - Q1
Quartlies of all the data:
1 62
2 88
3 89 --------------- first quartile, Q1 = 89
4 90
5 92
------------------------------------------ median, Q2 = (95 + 92) / 2 = 93.5
6 95
7 96
8 98 ---------------- third quartile, Q3 = 98
9 100
10 100
=> IQR = 98 - 89 = 9 : the interquartle range is 9
Quartlies without the outlier:
2 88
3 89
------------------------------------- first quartile, Q1 = (89 + 90) / 2 = 89.5
4 90
5 92
6 95 --------------- median, Q2 = 95
7 96
8 98
------------------------------------ third quartile, Q3 = (98 + 100) / 2 = 99
9 100
10 100
=> IQR = Q3 - Q1 = 99 - 89.5 = : the interquartle range without the outlier is 9.5
Therefore, the outlier impacts more the range than it impacts the IQR.
THE ONLY STATEMENT THAT IS FALSE IS THE NUMBER 5.

50/120
Step-by-step explanation:
8, 5, 12
8 = 2³
5 = 5
12 = 2² × 3
LCD = 2³ × 3 × 5 = 8 × 3 × 5 = 120
120/8 = 15
7/8 = (7 × 15)/(8 × 15) = 105/120
120/5 = 24
2/5 = (2 × 24)/(5 × 24) = 48/120
120/12 = 10

What would the surface area be ?
Answer:
320.44Step-by-step explanation:
the equation for right cylinder surface area: 2πrh+2πr^2
Answer:
33π cm²
Step-by-step explanation:
To find surface area you add the area of every face.
Area of the 2 circle faces:
The formula for the area of circle is πr². If the diameter is 6 you divide that by 2 to get a radius of 3. The area of the circle is 9π. Sense the top and bottom are both circles you multiply the area by 2 to get 18π.
Area of side face:
To find the area of the side, it is the same as a rectangle (length [circumference] multiplied by height [2.5]). The forumla for the circumference of a circle is πd. The circumference is 6π so multiply that by the height of 2.5 to get the area of the side of 15π.
Total surface area:
Now add the 18π (area of 2 circle faces) with the 15π (area of side face) to get 33π cm² surface area.
Solve for x by completing the square: x2 - 12x + 11 = 0
A.
(-11,0) and (1,0)
B.
(1,0) and (11,0)
C.
(0,1) and (0,-11)
Answer:
B
Step-by-step explanation:
x² - 12x + 11 = 0 ( subtract 11 from both sides )
x² - 12x = - 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 11 + 36
(x - 6)² = 25 ( take square root of both sides )
x - 6 = ± [tex]\sqrt{25}[/tex] = ± 5 ( add 6 to both sides )
x = 6 ± 5
Then
x = 6 - 5 = 1 ⇒ (1, 0 )
x = 6 + 5 = 11 ⇒ (11, 0 )

Answer:
20
Step-by-step explanation:
The grid lines are 1 unit apart, so you can determine the dimensions of the trapezoid by counting grid squares. The parallel bases have lengths 6 and 2. They are 5 units apart.
The area is given by ...
A = 1/2(b1 +b2)h
A = 1/2(6 +2)(5) = 20
The area of the trapezoid is 20 square units.

How much would it cost to buy x pounds of oranges? If oranges were 1.25$
Answer:
$20
Step-by-step explanation:
if one ound = 16 ounces then you would do 1.25x16 witch equals $20
If oranges were 1.25$ per pound. then the cost to buy x pounds of oranges would be 1.25x $.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If oranges were 1.25$ per pound. We need to find the cost to buy x pounds of oranges.
The cost of oranges per pound = 1.25$
The cost of oranges x pound = 1.25$ × x
= 1.25x $
Thus, The cost to buy x pounds of oranges would be 1.25x $.

Six students are running for the positions of president and vice-president, and five students are running for secretary and treasurer. If the two highest vote getters in each of the two contests are elected, how many winning combinations can there be?
Using the permutation formula, it is found that there can be 600 winning combinations.
There are roles involved(president, vice-president, secretary and treasures), hence the order is important and the permutation formula is used.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem:
For president and vice-president, 2 students are chosen from a set of 6.For secretary and treasurer, 2 students are chosen from a set of 5.Hence:
[tex]T = P_{6,2}P_{5,2} = \frac{6!}{4!} \times \frac{5!}{3!} = 30 \times 20 = 600[/tex]
There can be 600 winning combinations.

It takes 3 hours of 10 pumps to pump 40000 liters of water into a farm dam.How long will it take nine similar pumps to pump 60000 liters of water into the dam
It will take 5 hours to pump 60000L of water using 9 pumps
Data;
10 pumps = 40000L in 3 hours9 pumps = 60000L in x hoursRate of the PumpRate = Time * number of pumps
[tex]\frac{a}{3*10} = \frac{60000}{40000}\\ \frac{a}{30} = \frac{6}{4} \\a = 45[/tex]
But since we've established the equation above, let's substitute the values and solve for the time required to pump 60000L into the dam using 9 pumps as compared to 10 pumps. We can easily do this by calculating the rate of the pump.
Rate = time * number of pumps
