Answer:
x = 25.5
Step-by-step explanation:
Since there is a pair of parallel lines and a line cutting across the lines, ∠5 and ∠12 are interior angles and add up to 180°.
∠5 + ∠12 = 180°
5x - 11 + x + 38 = 180
Evaluate like terms.
6x + 27 = 180
Isolate 6x.
6x = 180 - 27
= 153
Find x.
x = 153 ÷ 6
x = 25.5

Answer:
A. Yes
B. Yes
C. No
D. No
Step-by-step explanation:
A is a linear equation, because it has an x with no exponent
B is a linear equation, because it has an x with no exponent
C is not a linear equation, because the exponent is more than 1
D is not a linear equation, because the exponent is more than 1

Paul needs to randomly select one of his four children to go first in a board game. Which simulation tools could he use in this situation?
1. a spinner divided evenly into 12 sections, with three sections each of four different colors. - Correct
2. a bag containing 12 chips in two different colors, with six of each color.
3. a standard deck of cards.
4. two coins -Correct
5. a six-sided number cube
Answer:
1/3/4 are all correct
Step-by-step explanation:
For Paul to select 1 of his 4 children, the simulation tool must have the possibility of giving a result of 1/4 (i.e. 1 in 4 children). The simulation tools capable of these results are: (1), (3) and (4)
To determine which simulation tool is correct for the situation, we simply put each option to test.
Option (1)
[tex]Sections = 12[/tex]
[tex]Sub= 3[/tex]
Here, the simulation is done by calculating the probability of each subsection.
The probability is:
[tex]Pr = \frac{Sub}{Sections}[/tex]
[tex]Pr = \frac{3}{12}[/tex]
Simplify
[tex]Pr = \frac{1}{4}[/tex]
Option 2
[tex]Chips =12[/tex]
[tex]Sections = 2[/tex]
Here, the simulation is done by calculating the probability of each section.
The probability is:
[tex]Pr = \frac{Sections}{Chips}[/tex]
[tex]Pr = \frac{2}{12}[/tex]
Simplify
[tex]Pr = \frac{1}{6}[/tex]
Option 3
A standard deck has:
[tex]Cards = 52[/tex]
[tex]Suit = 13[/tex]
Here, the simulation is done by calculating the probability of each suit.
The probability is:
[tex]Pr = \frac{Suits}{Cards}[/tex]
[tex]Pr = \frac{13}{52}[/tex]
Simplify
[tex]Pr = \frac{1}{4}[/tex]
Option 4
[tex]Coins = 2[/tex]
Here, he needs to toss the coin 2 times. So, the possible sample space are:
[tex]S = \{HH, HT, TH, TT\}[/tex]
The probability of one of the outcomes is:
[tex]Pr = \frac{1}{n(S)}[/tex]
Where:
[tex]n(S) = 4[/tex] ---- number of outcomes
So:
[tex]Pr =\frac{1}{4}[/tex]
Option 5:
[tex]Sides =6[/tex]
The probability of getting 1 of the 6 faces is:
[tex]Pr = \frac{1}{6}[/tex]
Paul can only use simulations that give 1/4. Hence, (1), (3) and (4) are correct because they all equal 1/4.

What is the radius of a hemisphere with a volume of 6466 to the nearest tenth of a meter?
Answer:
14.6m
Step-by-step explanation:
volume of a hemisphere = (2/3)πr3
Therefore r = Cube root of ( Volume * 3/2 * 1/ pi)
r = cube root ( 6466 * 3/2 * 1/ π)
r = 14.56
in the nearest tenth of a meter = 14.6 m
What is the absolute value of -27 1/3
The absolute value of -27 1/3 is 27 1/3. The meaning of absolute value is the distance from the number and zero. -27 1/3 is 27 1/3 away from zero.
Answer: 27 1/3
Reason: The absolute value is the distance from that number to zero, and that's why it's that answer.

Answer:
2x-3y+3=0
2x+y-3=0
Step-by-step explanation:
For 41.
points are (0,1) and (3,3)
Equation in two point form is
(x - 0)(3-1) = (3-0) ( y-1)
2x= 3y - 3
2x-3y+3=0
For 42.
Points are (0,3) and (2,-1)
Equation is
(x-0)(-1-3)=(y-3)(2-0)
-4x = 2y -6
4x + 2y -6 = 0
or 2x + y -3 = 0
