Answer:
Equation: 4x + 30 + 2x + 6 = 180
Answer: x = 24
Step-by-step explanation:
The sum of the measures of supplementary angles is 180 deg.
Equation:
4x + 30 + 2x + 6 = 180
Solution:
4x + 30 + 2x + 6 = 180
Add like terms on the left side.
6x + 36 = 180
Subtract 36 from both sides.
6x = 144
x = 24
Answer:
X=24
Step-by-step explanation:
Supplementary angles = 180°
4x+30+2x+6=180
Combine like terms> 4x+2x=6x
Add: 30+6=36
6x+36=180.
Subtract 36 on both sides. > 36-36=0. 180-36=144.
Drop what you have left> 6x 144
Divide by 6. > 6/6= 1. 144/6=24.
X=24
Question
The angles in
triangle are such that one angle is 100 degrees more than the smallest angle, while the third angle is 2 times
as large as the smallest angle. Find the measures of all three angles.
9514 1404 393
Answer:
20°, 120°, 40°
Step-by-step explanation:
Let s represent the smallest angle. Then the largest is (100+s) and the third angle is (2s). The sum of angles in a triangle is 180 degrees, so we have ...
s + (100+s) +(2s) = 180
4s = 80 . . . . . . . . . . subtract 100
s = 20 . . . the smallest angle
100+s = 120 . . . the largest angle
2s = 40 . . . the third angle
The angle measures are 20°, 120°, and 40°.
Maddy has a bag of 36 marbles. The probability of picking green is 1 in 2, the probability of picking red is 1 in 3, and the probability of picking blue is 1 in 9. The only other color in the bag is black. Find the probability of Maddy picking a black marble.
Answer: 1 in 18
This is the same as writing the fraction 1/18
==============================================================
Explanation:
Since she has 36 marbles total, and the probability of picking green is 1 in 2, this means (1/2)*36 = 18 marbles are green.
Then she also has (1/3)*36 = 12 red marbles and (1/9)*36 = 4 blue marbles.
So far, that accounts for 18+12+4 = 34 marbles in all. That leaves 36-4 = 2 marbles left over that must be black, as it's the only color left.
From that, the probability of choosing a black marble is 2/36 = 1/18.
There's a 1 in 18 chance of Maddy picking a black marble.
1/18 = 0.0556 = 5.56% approximately
Which of the following statements must be true
Answer:
only 3) is true. EC is equidistant (the same distance) to BD
Step-by-step explanation:
since we have no coordinates or other specific distance information for the various points and lines, we can only confirm statements that must be true for any placement of the lines inside a circle with the described attributes.
the distance EC could be the same as CB, but if we move ED further up or down in the circle (still parallel to CB), we can easily see, that this is not a general case.
the same for CB and BD.
since CB and BD are airways parallel to each other, the symmetry principle of a circle requires that the distance of EC is airways equal to the distance of BD for all such possible pairs of parallel lines inside the circle.
the graph itself gives an example that the distance CB and the distance ED do not have to be the same. they can be for certain pairs of parallel lines in the circle, but not for all of them.

A poll is given, showing 60% are in favor of a new building project.
If 7 people are chosen at random, what is the probability that exactly 5 of them favor the new building project?
Round this value however you need to.
==================================================
Explanation:
n = 7 = sample sizep = 0.60 = probability of someone being in favork = 5 = number of people in favorWe use the binomial distribution here. The formula for that is
P(k) = (n C k)*(p)^k*(1-p)^(n-k)
where the n C k refers to the nCr combination formula
[tex]_n C _r = \frac{n!}{r!*(n-r)!}[/tex]
simply replace r with k.
------------------------------
So,
P(k) = (n C k)*(p)^k*(1-p)^(n-k)
P(5) = (7 C 5)*(0.6)^5*(1-0.6)^(7-5)
P(5) = 21*(0.6)^5*(0.4)^(2)
P(5) = 21*0.07776*0.16
P(5) = 0.2612736
This decimal value is exact (meaning there aren't any other digits after that last '6'). Round this value however you need to.
There's roughly a 26.1% chance of getting exactly 5 people to be in favor of the project.

Which of the following best descifrar the graph shown below?
Answer: It's B
Step-by-step explanation:
27 exponent x divided by 3 is equal to one divided by 81.
27 exponent x/3 = 1/81
we can say exponent as power also
(27 power x) × (3 power -1) = 81 power -1
(3 power 3x) × ( 3 power -1) = 3 power -4
IN MULTIPLICATION WHEN BASES ARE SAME THEN POWERS ARE ADDED
3 power 3x + (-1) = 3 power -4
IN AN EQUATION WHEN BASES ARE EQUAL POWERS ALSO EQUAL
3x +(-1) = -4
3x - 1 = -4
3x = -4 + 1
3x = -3
x = -3/3
x = -1
Answer:
x = -1
Step-by-step explanation:
27 exponent x = [tex]27^x[/tex]
Divided by 3 = [tex]\frac{27^x}{3}[/tex]
Is equal to : [tex]\frac{1}{81}[/tex]
Therefore,
[tex]\frac{27^x}{3} = \frac{1}{81}[/tex]
Cross multiplying :
[tex]27^x \times 81 = 1 \times 3[/tex]
[tex]27^x = \frac{3}{81}[/tex]
[tex]27^x = \frac{1}{27}[/tex]
[tex]27^x = 27^{-1}[/tex]
[tex]x = -1[/tex] [tex][a^x = a^y => x = y][/tex]

Step-by-step explanation:
Fill in the table of values so that this is a proportional relationship with k=3/2 X. Y. *blank*. 0 2. *blank*. *blank*. 6. -2. *blank*
Answer:
x => y
0 => 0
2 => 3
4 => 6
-2 => -3
Step-by-step explanation:
The equation of a proportional relationship is represented as y = kx,
where, k = y/x
We are given that k = ³/2
This means that, equation of the relationship therefore would be:
y = ³/2x
Use this equation to solve for each missing value on the table given:
✔️Where, y = 0, substitute y = 0 into y = ³/2x to find x:
0 = ³/2x
0 * 2 = 3x
0 = 3x
0/3 = x
x = 0
✔️Where, x = 2, substitute x = 2 into y = ³/2x to find y:
y = ³/2(2)
y = 3
✔️Where, y = 6, substitute y = 6 into y = ³/2x to find x:
6 = ³/2x
6 * 2 = 3x
12 = 3x
12/3 = x
x = 4
✔️Where, x = -2, substitute x = -2 into y = ³/2x to find y:
y = ³/2(-2)
y = -3

A baseball is "popped" straight up by a batter with an initial velocity of 32 ft/sec. The height of the ball above ground is given by a function where t is time in seconds after the ball leaves the bat and h(t) is the height in feet above the ground. The batter hit the ball at an original height of 4 feet off of the ground, and the acceleration due to gravity is -16ft/se2
Answer:
The ball reaches the maximum height after 1 seconds
Step-by-step explanation:
Given
[tex]y = -16t^2 + 32t + 4[/tex] --- the function missing from the question
Required
Time to reach maximum height
The time (t) to reach maximum height is calculated using:
[tex]t = -\frac{b}{2a}[/tex]
Where
[tex]y =at^2 + bx + c[/tex]
So, by comparison:
[tex]a = -16[/tex]
[tex]b = 32[/tex]
[tex]c = 4[/tex]
So, we have:
[tex]t = -\frac{b}{2a}[/tex]
[tex]t = -\frac{32}{2*-16}[/tex]
[tex]t = -\frac{32}{-32}[/tex]
[tex]t = \frac{32}{32}[/tex]
[tex]t = 1[/tex]
