Jared spent 5 hours and 36 minutes on Flex line.
What is work done ?Work done is product of time taken and rate of work.
when the amount of work done is constant the more efficient a person is the lesser time it will require to complete the work this is also known as inverse proportion.
In the given question
Total hours of work done by Jared is 8 hours.
2/3rd of the time he spent on Flex line
2/3rd of 8 hours is
(2/3) × 8

PLS HELP, I'LL GIVE YOU NITRO ON DISC0RD!!! Jose ran a concession stand last Saturday and made $79.80 from selling a total of 42 hot dogs and hamburgers. Each hot dog sold for $1.50 and each hamburger sold for $2.70. Which system of equations can be used to determine the number of hot dogs, x, and hamburgers, y, that were sold?
Answer:
1.50x + 2.70y - 84 = 79.80
Explanation: I REALLY don't know if this is right, but I hope I helped you out at least a little bit.
Answer:
x + y = 42
1.50x + 2.50y = $79.80
x = 28 hot dogs
y = 14 hamburgers
Step-by-step explanation:
x = hot dogs
y = hamburgers
Equation:
x + y = 42
1.50x + 2.50y = $79.80
I used Substitution
x = 42 - y
1.50(42 - y) + 2.50y = 79.80
63 - 1.50y + 2.70y = 79.80
63 + 1.2y = 79.80
Substract 63 from both sides
1.2y = 16.8
Divide 1.2 on both sides
y = 14
x + y = 42
x + 14 = 42
x = 28
y = 14
Don't know how to explain that well, I hope this helps.

So, we have been given the following
[tex]-2(6x -y)[/tex]
But, we have also been given heads up that [tex]x=-3[/tex], and [tex]y=4[/tex].
So, that would mean the new equation would be the following.
[tex]-2(6-3 -4)[/tex]
After we solve it our answer should be [tex]2[/tex]!
If this helps then please mark me brainliest!
Answer:
-44Step-by-step explanation:
Given:
-2|6x -y|x = -3y = 4Solution:
-2|6*(-3) - 4| =-2|-22| =Absolute value is always positive, therefore |-22| = 22
-2*22 =-44A movie, including the previews, is 2 hours and 40
minutes long. If the previews last 20 minutes, what
fraction of the total time is the actual movie?
Answer:
7/8
Step-by-step explanation:
Given the length of the actual movie time and the length of the total movie time, the actual movie is 7/8 of the total movie time.
What fraction of the total time is the actual movie?Given the data in the question;
Total time of the movie is 2 hours and 40 minutes = 160 minutes
Preview time is 20 minutes
Now time of the actual movie will be;
Total time of the movie - Preview time
2 hours and 40 minutes - 20 minutes
160 minutes - 20 minutes
Time of the actual movie is 140 minutes
Now we get the fraction
Time of the actual movie / Total time of the movie
= 140 minutes / 160 minutes
= 14/16
= 7/8
Therefore, given the length of the actual movie time and the length of the total movie time, the actual movie is 7/8 of the total movie time.

What is the solution set for 5(1−p)>−3p−5?
3p-1=5(p-1)-2(7-2p)
Simplifying
3p + -1 = 5(p + -1) + -2(7 + -2p)
Reorder the terms:
-1 + 3p = 5(p + -1) + -2(7 + -2p)
Reorder the terms:
-1 + 3p = 5(-1 + p) + -2(7 + -2p)
-1 + 3p = (-1 * 5 + p * 5) + -2(7 + -2p)
-1 + 3p = (-5 + 5p) + -2(7 + -2p)
-1 + 3p = -5 + 5p + (7 * -2 + -2p * -2)
-1 + 3p = -5 + 5p + (-14 + 4p)
Reorder the terms:
-1 + 3p = -5 + -14 + 5p + 4p
Combine like terms: -5 + -14 = -19
-1 + 3p = -19 + 5p + 4p
Combine like terms: 5p + 4p = 9p
-1 + 3p = -19 + 9p
Solving
-1 + 3p = -19 + 9p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-9p' to each side of the equation.
-1 + 3p + -9p = -19 + 9p + -9p
Combine like terms: 3p + -9p = -6p
-1 + -6p = -19 + 9p + -9p
Combine like terms: 9p + -9p = 0
-1 + -6p = -19 + 0
-1 + -6p = -19
Add '1' to each side of the equation.
-1 + 1 + -6p = -19 + 1
Combine like terms: -1 + 1 = 0
0 + -6p = -19 + 1
-6p = -19 + 1
Combine like terms: -19 + 1 = -18
-6p = -18
Divide each side by '-6'.
p = 3
Simplifying
p = 3

can someone please help me witch is the answer 20 points to the one who can answer first
First, let's find the slope.
Slope = (7 - (-3)) / (2 - 0) = (7 + 3) / 2 = 10 / 2 = 5
So far our equation looks like: y = 5x + b
Leta plug one of the points into our equation to find b.
-3 = 5(0) + b
Simplify.
-3 = b
The equation is: y = 5x - 3
Answer choice B is correct.

The first two numbers in a sequence h are h(1) = 2 and h(2) = 6.
1. If h is an arithmetic sequence, write a definition for the nth term of h. Explain
or show your reasoning.
2. If h is a geometric sequence, write down a definition for the nth term of h. Show reasoning
Answer:
Step-by-step explanation:
Given the first two numbers of a sequence as 2, 6...
If it is an arithmetic difference, the common difference will be d = 6-2 = 4
Formula for calculating nth term of an ARITHMETIC sequence Tn = a+(n-1)d
a is the first term = 2
d is the common difference = 4
n is the number if terms
Substituting the given values in the formula.
Nth term Tn = 2+(n-1)4
Tn = 2+4n-4
Tn = 4n-4+2
Tn = 4n-2
2) If the sequence us a geometric sequence
Nth term of the sequence Tn = ar^(n-1)
r is the common ratio
r is gotten by the ratio of the terms I.e
r = T2/T1
r = 6/2
r = 3
Since a = 2
Tn = 2(3)^(n-1)
Hence the nth term of the geometric sequence is Tn = 2(3)^(n-1)

You roll a six-sided die. Find the probability of each of the following scenarios. (a) Rolling a 5 or a number greater than 3. (b) Rolling a number less than 5 or an even number. (c) Rolling a 2 or an odd number
Answer:
Step-by-step explanation:
a.
let A= number 5
B=number >3
P(A)=1/6 {5}
P(B)=3/6 {4,5,6}
p(A∩B)=1/6 {5}
P(AUB)=P(A)+P(B)-P(A∩B)=1/6+3/6-1/6=3/6=1/2
b.
let event C=number<5
D=even number
C=[1,2,3,4}
D={2,4,6}
C∩D={2,4}
P(C)=4/6
P(D)=3/6
P(C∩D)=2/6
P(C∪D)=P(C)+P(D)-P(C∩D)=4/6+3/6-2/6=5/6
c.
let event E=number 2
F= an odd number.
E={2}
F={1,3,5}
E∩F={}
P(E)=1/6
P(F)=3/6
P(E∩F)=0
P(E∪F)=P(E)+P(F)-P(E∩F)=1/6+3/6-0=4/6=2/3
