Easy Question About Area
Answers
Answer:
Option C.
Step-by-step explanation:
In the figure attached, a triangle has been given with angles.
m∠F = 73°
m∠D = 48°
And m∠E = 180° - (73 + 48)° = 59°
∠D < ∠E < ∠F
Since opposite sides of the largest angle in a triangle is longest and opposite side of the smallest angle is shortest,
Hence, d < e < f
Therefore, order given in Option C will be the answer.
Answer:
d, e, f

Which ordered pair is generated from the equation shown below?
y = 3x + 2
A) (3, 11)
B) (3, 9)
C) (5, 15)
D) (2, 4)
Answers
Answer:
(3, 11)
Step-by-step explanation:
To check the ordered pair from given option .
lets plug in the value of x from the choices given .
If value of y is same a sin ordered pair then that pair is correct answer else it can be concluded that pair is not generated from equation given.
equation: y = 3x + 2
_____________________________________
A) (3, 11)
If we put value of X=3 in equation y = 3x + 2,
then y should be 11
y = 3x + 2
=> y = 3*3+2 = 9+2 = 11 . (This is as expected for ordered pair)
Hence this pair (3, 11) is generated from given equation.
_____________________________________
A) (3, 9)
If we put value of X=3 in equation y = 3x + 2,
then y should be 9
y = 3x + 2
=> y = 3*3+2 = 9+2 = 11 . (This is not as expected for ordered pair(3,9)
Hence this pair is not generated from given equation.
_____________________________________
A) (5, 15)
If we put value of X=5 in equation y = 3x + 2,
then y should be 15
y = 3x + 2
=> y = 3*5+2 = 15+2 = 17 . (This is not as expected for ordered pair(5,15)
Hence this pair is not generated from given equation.
_____________________________________
A) (2, 4)
If we put value of X=3 in equation y = 3x + 2,
then y should be 9
y = 3x + 2
=> y = 3*2+2 = 6+2 = 8. (This is not as expected for ordered pair(2, 4)
Hence this pair is not generated from given equation.
_________________________________________________
Thus, only A) (3, 11) is generated from the equation y = 3x + 2

B) T+8
C) T+0.08
D) 1.08T
E) (1 + 8/100) T
Answers
Answer: 1.08T and (1+8/100)T
Step-by-step explanation:
Given: The average temperature two Sundays ago was T degrees Celsius.
Since, last Sunday, the average temperature was 8% higher than the average temperature two Sundays ago.
⇒ The average temperature last Sunday
Since 8%=0.08
Therefore, The average temperature last Sunday
⇒ The average temperature last Sunday
⇒ The average temperature last Sunday
⇒ The average temperature last Sunday
Thus, the right option is 1.08T and (1+8/100)T

Answers
Answer:
9a) corresponding
9b) Congruent
9c) x=5
10) x=4
11=9
Step-by-step explanation:
9a. The angles are corresponding, as, if you look at the 8 angles as 2 groups of 4, they would be in the same spot.
b. Corresponding angles are congruent (by corresponding angles are congruent theorem)
c. Because the angles are congruent, we know that
23x-5=21x+5
23x-21x=5+5
2x=10
x=5
10. We know that (see attached photo) angle a is equal to angle b through the vertical angle theorem. Then, we know that angle b is equal to angle c through corresponding angles. So, we know that a=b, and b=c, so through the transitivity property, a=c, and c=90 degrees (it is a right angle)
Therefore, a=90 degrees
a=21x+6, so 21x+6=90
21x=84
x=4
11) This is almost the exact same problem as 10. We know that (see attached photo) a=b through vertical angles, and b=c through corresponding angles. Therefore, a=c
When you substitute the values of the two angles, we get:
-1+14x=12x+17
14x-12x=17+1
2x=18
x=9
Jerry's team has played 8 games of basketball. During those 8 games his team scored 59, 66, 56, 63, 42, 55, 62 and 51. What is the range in the number of points scored for each game?
A) 20
B) 22
C) 24
D) 26
Answers
Answer:
To calculate the mean of a set of data, you have to work out the sum of the data (in this case, you need to work out the sum of all the points) and divide it by the number of data points there are (in this case, number of games played).
So you have to do:
(67 + 45 + 84 + 55 + 73 + 36 + 80 + 62 + 38)/9 = 60
The mean number of points is 60.

40 POINTS!!!!!!!!! Given the following system of equations and their graph below, what can be determined about the slopes and y-intercepts of the system of equations? A line includes points 6 comma 1 and 4 comma 0. 3x − 6y = 12 9x − 18y = 36 The slopes are different, and the y-intercepts are different. The slopes are different, and the y-intercepts are the same. The slopes are the same, and the y-intercepts are different. The slopes are the same, and the y-intercepts are the same.
Answers
Answer:
The slopes are the same and the y-intercepts are the same.
Step-by-step explanation:
Looking at the two systems of equations:
3x - 6y = 12
and
9x - 18y = 36
We can see that the two equations have a GCF, that GCF would be 3.
Since, 3 ( 3x - 6y = 12) = 9x - 18y = 36
or vice versa: (9x - 18y = 36)/3 = 3x - 6y = 12
Therefore, both the slopes and the y-intercepts are the same just dilated by a factor of 3.
Answer:
The slopes are the same and the y-intercepts are the same.

The required quart that leaks is 4 quart, faucet leak per hours.
A faucet leaks water at constant rate of quat every 15 minutes. How many quarts does the faucet leak per hour to be determined.
What is rate of change?
Rate of change is defined as the change in value with rest to the time is called rate of change.
1 quart = 60 units
Every 15 minutes, 1 quart has been leaked from the faucet.
1 quart will be leaked fully = 15 minutes
Divide by 15 into both sides
1 / 15 quart will be leak fully = 1 minute
multiply both sides by 60
60 / 15 quart will be leak fully = 60 minute
4 quart will be leaked fully = 1 hour (60 min = 1 hour)
Thus, 4 quarts does the faucet leak per hours.

Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius ), thus
V = [tex]\frac{4}{3}[/tex]π × 5³
= [tex]\frac{4}{3}[/tex]π × 125 = [tex]\frac{4(125)}{3}[/tex]π = [tex]\frac{500}{3}[/tex]π units³ → D
The volume of the sphere of the given figure is [tex]\frac{500}{3} \pi units^{3}[/tex] .Option D is correct.
It is given that the radius(r) of the sphere is 5 unit.
It is required to find the volume of the sphere of the given figure.
What is the volume of the sphere below?As we know the volume of the sphere is:
V = [tex]\frac{4}{3} \pi r^{3}[/tex]
Where, r represents the radius of the sphere.
Now putting the value of 'r' in the formula,
V = [tex]\frac{4}{3}\pi (5)^{3}[/tex]
V = [tex]\frac{4}{3} \pi[/tex]×(125)
V = [tex]\frac{4 (125)}{3}\pi[/tex]
V = [tex]\frac{500}{3} \pi[/tex] [tex]unit^{3}[/tex]
Thus, the volume of the sphere of the given figure is [tex]\frac{500}{3} \pi units^{3}[/tex] .

Find the exact value of sec30°.
Answers
Decimal Form:
1.15470053
…
Step-by-step explanation:
The exact value of sec(30°) is 2√3 / 3.
We have,
To find the exact value of sec(30°), use the trigonometric identity:
sec(θ) = 1 / cos(θ)
Now,
cos(30°) = √3 / 2
Now, substitute this value into the formula for sec(θ):
sec(30°) = 1 / cos(30°) = 1 / (√3 / 2)
sec(30°) = 2 / √3
To rationalize the denominator, multiply the numerator and denominator by √3:
sec(30°) = 2 / √3 * √3 / √3
= 2√3 / 3
Therefore,
The exact value of sec(30°) is 2√3 / 3.

Answer:

If you look closely an multiply 4 x 8, it equals 32, not 48

Answer:
4x = 48
Step-by-step explanation:
Since x = 8,
4x = 48
4 * 8 = 32
So 32 is the LHS and 48 is the RHS.
Since the LHS is not equal to the RHS, x=8 is not a solution to the equation 4x = 48

A sector with an area of 140 pie cm^2 has a radius of 20 cm.

A = 140 pie cm^2
What is the central angle measure of the sector in degrees?
Answers
Answer:
Central angle = 126°
Step-by-step explanation:
Area of the sector = 140π cm²
Radius of the given circle = 20 cm
Since area of the sector = [tex]\frac{\theta}{360}\times (\pi r^{2})[/tex]
[where θ is the central angle formed by the sector at the center]
140π = [tex]\frac{\theta}{360}(\pi)(20)^{2}[/tex]
θ = [tex]\frac{(140\pi)\times 360}{400\pi }[/tex]
θ = 126°
