Answer:
25/3
Step-by-step explanation:
Set the equations equal to each other since the lines are parallel.
(x+20)=(4x-5)
-x +5 -x +5
25/3 = 3x/3
x = 25/3
For a fairground ride the maximum weight of a person is 100kg to the nearest kg.
What is the maximum a person can weigh to go on the ride safely
Answer:
The maximum a person can weigh to go on the ride safely is 100.5 kg
Step-by-step explanation:
The specification for the maximum weight of each person that goes on the ride = 100 kg
Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;
[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg
the table shows the linear relationship between the percentage of construction job remaining and the number of days that have passed

Step-by-step explanation:
What is the rate of change of e=3h+200
Answer:
3
Step-by-step explanation:
"Rate of change" is the real-world problem way of saying "slope."
So whenever a question asks you to find "rate of change", simply look for the slope.
y = mx + b
e = 3h + 200
mx = slope/rate of change
So, 3 would be your answer.

V = 4 + 2r solve for r
Answer:
r = V/2 - 2
Step-by-step explanation:
Answer: r=1/2v−2
Step-by-step explanation:
v=4+2r
2r+4=v
2r+4+−4=v+−4
2r=v−4
2r/2=v−4/2
r=1/2v−2
please help! thanks
i kinda need it soon too
Answer:
43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)
38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)
19 is what goes in the box

Use the given substitution and the chain rule to find
dy/dx
y=cos (6x - 5), u = 6x-5
Substituting u = 6x - 5, you write
y = cos(u)
Then differentiating with the chain rule gives
dy/dx = dy/du • du/dx
We have
dy/du = -sin(u)
du/dx = 6
so
dy/dx = -6 sin(u) = -6 sin(6x - 5)
What is -25.83538 times 29 to the power of three divided by 27.954?
can you help me I dont know the answer
Answer: C) Neither positive nor negative -- the sum is zero
Adding any positive number to its negative counterpart always leads to 0.
We could come up with a story problem where a person has $37 in their bank account, and then they take out $37 which is represented with the negative number. This leads the balance to become 37+(-37) = 37-37 = 0 dollars.

After school, Diana had a science club meeting for 1 hour and 20 minutes, followed by a choir rehearsal that lasted for 1 hour and 35 minutes. If Diana got out of school at 1:40 P.M., what time did the choir rehearsal end?
Answer:
3:15PM
Step-by-step explanation:
If If Diana got out of school at 1:40 P.M, this and spent 1 hour 35 minutes at the rehearsal, to know the time that the choir rehearsal ends, we will have to add the time spent at rehearsal to the time he got out of school;
1:40 P.M + (1hr 35 minutes)
1:40 P.M + 1 hr = 2:40PM
2:40PM + 35mintes = 2:40PM + (20mintes) +15 minutes
[2:40PM + (20mintes)] +15 minutes = 3:00pm + 15 minutes
3:00pm + 15 minutes = 3:15PM
Hence the choir rehearsal ends at 3:15PM

Answer:
picture from Goldbach's conjecture.
Step-by-step explanation:
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states:
Every even integer greater than 2 is the sum of two primes.
The conjecture has been shown to hold for all integers less than 4 × 10^18, but remains unproven despite considerable effort.
So on the red and blue axes you see primes. The list of black numbers are even numbers.

this is geometry pls help
Answer:
the answer for this is B 9
Answer:
B
Step-by-step explanation:
Consecutive angles are supplementary, thus
30 + 5x + 15 + 10x = 180 , that is
15x + 45 = 180 ( subtract 45 from both sides )
15x = 135 ( divide both sides by 15 )
x = 9 → B
A store has apples on sale for $15.00 for 6 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $60.00? Complete the explanation.
The cost per pound of the apples on sale is $15.00
.
You can buy __ pounds of apples for $60.00.
Since 1 pound = 16 ounces, so there are about __ apples in each pound.
You can buy approximately __apples for $60.00.
Answer:
24 pounds of apples for $60
about 3 apples per pound
about 72 apples for $60
Step-by-step explanation:
$15 times 4 = $60, therefore 6 pounds times 4 = 24 pounds
5 out of 16 ounces equals about 3 apples per pound
24 pounds, with 3 apples in each pound, equals 72
