I need help on this one
Answer:
= 1/26
Step-by-step explanation:
Use Division Distributive Property:
(x/y)^a = x^a/y^a
(^, That means to the power of exponents.)
Then you Simplify 6^3 to 216
Then you will get 1 over 216.

Step-by-step explanation:
An experiment consists of rolling a number cube (dice). What is the probability of rolling a number GREATER THAN 4? Express your answer as a fraction in the simplest form.
Answer:
1/3
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur
Probability = Expected/Total outcome
Since the experiment requires rolling a dice
S = {1, 2, 3, 4, 5, 6}
Total outcome n(S) = 6
Number greater than 4 are;
Events E = {5,6}
Expected outcome n(E) = 2
Probability of rolling a number greater then 4 = 2/6
Probability of rolling a number greater then 4 = 1/3

Find the distance between the two points in simplest radical form.
(-5,6) and (-3,-1)
Answer:
√53
Step-by-step explanation:
Formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x1 = -5
x2 = -3
y1 = 6
y2 = - 1
Solution
d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )
d = sqrt( ( -3 + 5)^2 + (-7)^2 )
d = sqrt( 2^2 + 49)
d = sqrt(4 + 49)
d = sqrt(53)

Ronald has 5 2/3 cups of a smoothie he then drank 1 3/4 cups of the smoothie how many cups were left
Answer:
4 1/6 cups of the smoothie were left.
Step-by-step explanation:
The LCD here is (3)(4) = 12.
Thus, 5 2/3 cups equals 5 8/12 and 1 3/4 cups equals 1 6/12 cups.
Subtract 1 6/12 cups from the original 5 8/12 cups. We get:
5 8/12
-1 6/12
-----------
4 2/12, or 4 1/6.
4 1/6 cups of the smoothie were left.

y = -x-4
C.
y=x+4
by=-x+4
d. y = x-4
Answer:
y = -x + 4
Step-by-step explanation:
Mathematically, the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from the plot, the y intercept is 4
So we have;
y = mx + 4
To get the value of m, we substitute the coordinates of any point and solve for m
we select the point; (4,0)
so;
0 = m(4) + 4
4m = 0-4
4m = -4
m = -1
so the equation of the line is;
y = -x + 4

Rearrange w= 3(2a + b) – 4 to make a the subject.
Answer:
a = (w - 3b + 4)/6
Step-by-step explanation:
w = 3(2a + b) - 4
w = 6a + 3b - 4
6a + 3b - 4 = w
6a = w - 3b + 4
a = (w - 3b + 4)/6
Two trains are 1.5 miles apart, train a is traveling at 3/4 the speed of train b if they meet in 4 minutes how fast is each train going
Answer:
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.
Step-by-step explanation:
Let suppose that train A begins in position [tex]x = 0\,mi[/tex] and the train B in position [tex]x = 1.5\,mi[/tex], if [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and both trains move at constant speed, then we have the following kinematic equations:
Train A
[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex] (1)
Train B
[tex]x_{B} = x_{B,o}-v_{B}\cdot t[/tex] (2)
If both trains meet each other, then [tex]x_{A} = x_{B}[/tex]. If we know that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 1.5\,mi[/tex], [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and [tex]t = \frac{1}{15}\,h[/tex], then we have the following expression:
[tex]x_{A,o}+v_{A}\cdot t = x_{B,o}-v_{B}\cdot t[/tex]
[tex]x_{A,o} + v_{A}\cdot t = x_{B,o} - \frac{3}{4}\cdot v_{A}\cdot t[/tex]
[tex]\frac{7}{4}\cdot v_{A}\cdot t = x_{B,o}-x_{A,o}[/tex]
[tex]v_{A} = \frac{4\cdot (x_{B,o}-x_{A,o})}{7\cdot t}[/tex]
[tex]v_{A} = 12.857\,\frac{mi}{h}[/tex]
Then, the speed of the train B is:
[tex]v_{B} = 9.643\,\frac{mi}{h}[/tex]
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

7th grade math help me pleaseeee
Answer:
Ryan: 25 + 10h Alex: 20 + 11h
Mr. Smith should choose Alex - see below for reasoning
Step-by-step explanation:
The set-up fee does not change. It has no variable because it's already chosen. However, $/hour has a variable because the more hours a photo session takes, the more this number will increase when multiplied. Mr. Smith provides a good example of this. In his situation, h = 2 because his photo session will take two hours. If he hired Ryan, it would be $25 in set-up fees and then ten dollars per hour (h): [tex]25+10(2)[/tex] which totals out to $45. If he hired Alex, he would pay $20 for set-up fees and eleven dollars an hour (h): [tex]20+11(2)[/tex] which totals out to $42. So, Mr. Smith can save a few bucks if he hires Alex.
However, if someone expected hours and hours of photos - say, a fourteen-hour long photo session - then Ryan would be a better choice. His price would be [tex]25+10(14)[/tex] which totals to $165. Alex's price would be [tex]20+11(14)[/tex] which totals to $174. But I doubt anyone is going to want a fourteen-hour photo shoot, and I don't think Ryan nor Alex would want to do that either...

HELP ME IM STUCK ANSWER IT QUICK
Answer:
red = 28 apples
green = 13 apples
equations:
r + g = 41
r = g + 15
Step-by-step explanation:
r = number of red
g = number of green
r = g + 15 (the number of red apples is 15 more than the number of green apples)
r + g = 41
Substitute the firs equation into the second and solve for a numerical value of g
(g + 15) + g = 41
2g + 15 = 41
2g = 26
g = 13
Now solve for a numerical value of r
r = g + 15
r = 13 + 15
r = 28
checking the math:
r + g = 41
28 + 13 = 41

18 and 74 are true.
Step-by-step explanation:
So we want to solve this inquality. [tex]13+4x> 75\\[/tex] We subtract 13 from the left and the right. It leaves us with [tex]4x>62[/tex]. Then we want the x by itself so we divide the 4 from 4x and 4 from 62. We get [tex]x> 15 \frac{1}{2}[/tex]. So 15.5 is false since its not greater than. 0 is not a solution. 18 and 74 are true.

Answer:
See solutions below
Step-by-step explanation:
Complete question
A circle's circumference is approximately 44 cm.
Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.
The circle's diameter is approximately cm.
The circle's radius is approximately cm.
The circle's area is approximately cm2.
Circumference of the circle =2πr
r is the radius of the circle
Circumference of the circle = 2(3.14)r
44 = 2(3.14)r
22 = 3.14r
r = 22/3.14
r = 7.0cm
The circle's radius is approximately 7cm.
Since diameter = 2r
diameter = 2 * 76
diameter = 14cm
The circle's diameter is approximately 14cm.
Area of the circle = πr²
Area of the circle = 3.14(7)²
Area of the circle = 3.14(49)
Area of the circle = 153.86sq.cm
The circle's area is approximately 154cm^2.
