I'm pretty sure it's y= 45+25x
Answer:
y=45 + 25x
Step-by-step explanation:
When a question is asking for an initial fee, they are basically saying that you must pay that flat amount in addition to the amount you would pay for x hours of work. Say you work 5 hours. You have to multiply the number of hours, or x, by 25, then add 45.

Tires are rotating at a rate of 32 revolutions per minute. Find the angular speed of the tires in radians per minute.
Answer:
201.1 radians per minute
Step-by-step explanation:
The formula for Angular speed of tires in radians per minute =
1 revolutions per minute = 2π rad/min
32 revolutions per minute = x
x = 32 revolutions per minutes × 2 π radians per minute
x = 201.06192983 radians per minute
Approximately
x = 201.1 radians per minute
Therefore, the angular speed of the tires in radians per minute is 201.1 radians per minute
The angular speed of the tires in radians per minute is 201 rad per minute.
Angular speed is the rate at which an object changes it angles, it is measured in radians in a given time.
To convert from rad per minute to rev per minute, we divide by 2π.
1 rad per min = 1/2π rev per min
32 revolutions per minute = (32 * 2π) radians per minute = 201 rad per minute.
The angular speed of the tires in radians per minute is 201 rad per minute.

C 17. At high school A, the mean score of 50 students on a science test is 75.
At high school B, the mean score of 40 students on the same test is 80.
What is the mean score of the 90 students?
Answer:
Mean score of 90 students = 77.2
Step-by-step explanation:
Mean score of 50 students from school A = 75
Mean score of 40 students from school B = 80
We need to find mean score of the 90 students?
First we will find sum of scores of students from school A
We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]
We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]
So, Sum of scores for School A = 3750
Now, we will find sum of scores of students from school B
We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]
We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]
So, Sum of scores for School B = 3200
Now, We will find mean score of the 90 students?
Mean score of 90 students will be:
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]
So, mean score of 90 students = 77.2

Answer:
the ball costs $0.05
Step-by-step explanation:
if the total is $1.10, and the bat is $1 more than the ball, you do
1+2x=1.10. do the algebra, and you get 0.05. hope this helps.

Find the value of F, correct to two decimal places
Answer:
F = 12.14 m
Step-by-step explanation:
F is the side opposite the given 36° angle and the given side length, 15m is adjacent. It's a cosine equation that's needed.
find the cosine of 36°
(calculator necessary)
cos(36) = 0.8090169944
We should be safe to round that to .809 for this.
cos = opp/adj
Substitute what we know:
.809 = F/15 Multiply both sides by 15
.809(15) = F
12.135 = F Round to two places.
Side F is 12.14m

PLEASE HELP ILL MARK BRAINLY One of the tables shows a proportional relationship.
Graph the line representing the proportional relationship from this table.
Answer:
A proportional relationship is something like:
y = k*x
where k is the constant of proportionality.
Notice that in these relationships we will always have the pair (0, 0)
because if x = 0:
y = k*0 = 0
Then we always have x= 0, y = 0.
Notice that in the first two tables we have the points:
(2, 0) in the first one
(0, 1) in the second one.
then neither of these can be a proportional relationship.
The only option left is the third one.
To graph the relationship, we can just graph the four points in the table.
Then draw a line that passes through all the points, like in the image below.
And this line is written as:
y = 3*x
such that:
y(1) = 3*1 = 3 -----> (1, 3)
y(2) = 3*2 = 6 -----> (2, 6)
y(3) = 3*3 = 9 ------> (3, 9)

The speed, S, of a bicycle varies directly with the number of revolutions per minute, R, that the pedals turn and the number of teeth on the front gear, F, and inversely with the number of teeth on the back gear B.
ANSWERS
Cooling down, Lars pedals 56 rpms. Which equation shows his speed?
S=(56) (52)/ (13) (14)
Cooling down, the speed of the bicycle is
⇒ 16 mph.
Question is incomplete :
The speed, S, of a bicycle varies directly with the number of revolutions per minute, R, that the pedals turn and the number of teeth on the front gear, F, and inversely with the number of teeth on the back gear B.
Lars is racing at 24 miles per hour. His front gear has 52 teeth and a back gear has 14 teeth. He is pedaling 84 revolutions per minute. As he sprints for the finish line, he pedals 112 revolutions per minute. What is his speed?
Answer:
32 mph
Step-by-step explanation:
Speed α number of revolutions α number of teeth on front gear α 1/teeth on back gear
Speed = S ; number of revolutions = R ; Number of teeth on front gear = F ; Number of teeth in back gear = B
S = k(R * F) / B
k = proportionality constant ;
24 = k(84 * 52) / 14
24 * 14 = 4368k
k = 336/4368
k = 0.0769230
Speed at R = 112
S = k(R * F) / B
S = 0.0769230(112 * 52) / 14
S = 447.999552 / 14
S = 31.999968
S = 32 mph

Solve scale drawing problems Learn with flashcards, games, and more — for free. ... A plum tree is 7 inches tall on the scale drawing. What is ... The scale factor is 1/20. ... Josh wants to add a model of a tree to his model railroad layout. How big should the model tree be if the actual tree is 315 inches and the scale is 1:90?
Answer:
4.5 inches
Step-by-step explanation:
The scale factor is 1:20 which is 1/20, and the actual height is 90 inches.
First, write down the proportion:
1/20 = x/90
Multiply both sides by 90.
=> x = 90/20
=> x = 4.5in
Therefore, the height of the model is 4.5 inches.

Which expression is equilvalent to 2(x+y)+4(x+y)+8(x-y)?
Answer:
14x-2y
Step-by-step explanation:
just break down the expression by combining like terms and getting rid of the parenthesis like so:
2(x+y)+4(x+y)+8(x-y)
i multiplied the number in front of each parenthesis with both numbers inside
ex: 2(x+y)
2x+2y
result:
2x+2y+4x+4y+8x-8y
next:
14x-2y
Answer:
14x -2y
Step-by-step explanation:
2( x + y ) + 4( x + y ) + 8( x - y )
First, do the distributive property ( multiply what is in the parenthesis by what is out of it)
2( x + y ) + 4( x + y ) + 8( x - y )
2 * x + 2 * y + 4( x + y ) + 8( x - y )
2x + 2y + 4( x + y ) + 8( x - y )
2x + 2y + 4 * x + 4 * y + 8( x - y )
2x + 2y + 4x + 4y + 8( x - y )
2x + 2y + 4x + 4y + 8 * x + 8 * -y
2x + 2y + 4x + 4y + 8x - 8y
Now combine like terms
14x -2y
And you cannot simplify it anymore
Hope this helped!
