The marble was traveling at 4.05 miles per hour.
Since in science class, Antonio and Anna were measuring the approximate speed of a marble as it exits from an 8-foot-long ramp, and they discovered that it took 2.1 seconds for the marble to travel 12.5 feet from the end of the ramp, to determine approximately how fast was the marble traveling as it exited from the ramp to the nearest hundredth of a second, the following calculation must be performed:
12.5 / 2.1 = X 5.95 = X = feet per second 1 foot per second = 0.681818 miles per hour 5.95 x 0.681818 = X 4.05 = X
Therefore, the marble was traveling at 4.05 miles per hour.

|3(x-2)|=12 Please explain too!
Answer:
x = 6
Step-by-step explanation:
To solve the value of x
3(x-2)=12
First solve the brackets
3x -6 = 12
Now Transpose
3x = 12 + 6
3x = 18
x = 18 ÷ 3
x = 6
The value of x will be 6
What is the y-intercept of the line 3x-4y=24
Answer:
(0,-6)
Step-by-step explanation:
3x-4y=24
To find the y intercept, let x =0 and solve for y
3(0) -4y =24
-4y =24
Divide by -4
-4y/-4 = 24/-4
y = -6
The y intercept is
(0,-6)

Answer:
Step-by-step explanation:
We have to do an expression doing A - B
So we have to subtract A-B, let us see what we can do.
Distance between AB
= A - B
B = 0.5
A = -2.5
= 0.5 - (-2.5)
= 0.5 + 2.5
= 3
The additional inverse of the number a is the number that, when added to a , yields zero.

4. Bob spent $30 playing paintball which
included a $16 entry fee and $3.50 per hour of
play. How many hours did Bob play?
Answer: 4 hours
Step-by-step explanation:
First, set up an equation. We know that Bob spent $30 on playing paintball so we use that as our 'answer.' We need to find how many hours Bob played so we need to use x, a variable to find it. We also add 16 because we need to account for the entry fee.
3.50x + 16 = 30
Secondly, solve for x. Move 16 across the equal sign(=). Every time you move across the =, you're going to want to change the sign (if it's addition or subtraction). Since it was +16 and we're moving it, it's now -16.
3.50x = 30 - 16
Calculate 30 - 16 = 14.
Now we have
3.50 x = 14.
To calculate x, we're going to need to divide 3.50 from x. Since we multiplied by x we need to do the opposite across the =.
x = 14 / 3.50
x = 4
Bob spent 4 hours playing paintball.
You can plug it in to check answers as well
3.50 (4) +16 = 30

Five years ago, Enormous State University's campus publication, The Campus Inquirer, ran a total of 11 exposés dealing with alleged recruiting violations by the football team and with theft by the student treasurer of the film society. Each exposé dealing with recruiting violations resulted in a $3 million libel suit, and the treasurer of the film society sued the paper for $2 million as a result of each exposé about his alleged theft. Unfortunately for The Campus Inquirer, all the lawsuits were successful, and the paper wound up being ordered to pay $29 million in damages. (It closed down shortly thereafter.) How many of each type of exposé did the paper run? exposés on the football team exposés on the film society treasurer

How much lighter is 345 g than 1,1 kg
Answer:
755 gram lighter
Step-by-step explanation:
Convert 1.1kg into gram by multiplying it with 1000
1.1 x 1000= 1100 and we take this amount and subtract it with 345g
1100-345= 755g
