To find miles to inches, multiply by 63360 to get the answer.
0.5 x 63360 = 31680
So, he traveled 31680 inches.
A cyclist rides his bike at a rate of 15 miles per hour. What is this rate in miles per minute? How many miles will the cyclist travel in 10 minutes?
Answer:
This is 0.25 miles per minute
The cyclist would travel 2.5 miles in 10 minutes
Step-by-step explanation:
The equation to convert miles per hour to miles per minute is to divide by 60, the number of minutes in an hour.
What number when increased by 15% becomes 299 Please help willl mark brainest!
Let's make an equation with the information given.
A 15% increase in a number means that the number was multiplied by 1.15.
[tex]1.15x=299[/tex]
[tex]x=260[/tex]
Hope this helps.
頑張って!
Answer:
260
Step-by-step explanation:
Let's call the number x.
When x is increased by 15% it is equal to 299. The number itself is 100%, so we should multiply x by 115%. Convert 115% to a decimal. Divide 115 by 100 or move the decimal place two spots to the right.
115/100= 1.15 or 115.0 --> 11.5 --> 1.15
When x and 1.15 are multiplied they should equal 229. Set up an equation.
1.15x=229
We want to solve for x. Therefore, we must isolate x on one side of the equation. x is being multiplied by 1.15 The inverse of multiplication is division. Divide both sides of the equation by 1.15
1.15x/1.15=229/1.15
x=229/1.15
x=260
When 260 is increased by 15% the result is 299.

To simplify this expression, we combine all the like terms. We cannot solve for x because there is no equal sign and/or no value for x.
Equation: (10x² - 10x - 6) + (x + 6)
[tex]\bf Step~1:[/tex]
-10x and x are like terms. Remember: there is an invisible 1 behind the variable x. We add these like normal numbers.
[tex]\bf -10x+1x=-9x[/tex]
[tex]\bf Step~2:[/tex]
-6 and 6 are also like terms. Again, we add them as written.
[tex]\bf -6+6=0[/tex]
Since our answer is 0, we do not have to write it in our simplified expression.
[tex]\bf Step~3:[/tex]
Now, let's add the terms together. Since 10x² doesn't have any like terms, we just let it be. We take our previous number, -9x, and we add it to 10x².
[tex]\bf 10x^2+-9x[/tex]

The manager of a factory collected data in order to analyze the relationship
between the number of hours of training a worker receives and
the worker's error rate. The line of best fit for the collected data is y = 0.1 -0.005x, where x is the number of hours of training a worker
receives and y is the error rate.
What approximate error rate should the manager expect for a worker who receives 6 hours of training?

Given segment AC and point B that lies on AC, if AB = 9 and BC= 49, find AC
Answer:
58
Step-by-step explanation:
Let's draw this out (see attachment).
We know that since B lies on AC, we have the points in order from left to right: A, B, C.
AB = 9, which is the left portion. BC = 49, which is the right portion. Then AC is simply the sum:
AC = AB + BC = 9 + 49 = 58
The answer is thus 58.

Leanne works at a restaurant. For dinner, there is a choice of 3 main dishes and 2 sides.
Main Dish: Burger(B), Chicken (C), Pasta (P)
Sides: Apple (A), Fries (6)
Leanne lists all possible ways a person could order their dinner. She lists these combinations:
BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP.
Is Leanne correct? Use the drop-down menus to explain your reasoning.
Click the arrows to choose an answer from each menu.
For each main dish, there are Choose... different sides a person can choose. So, there are
a total of Choose... possible ways a person could choose their dinner. Leanne is
Choose...
Answer:
I feel like its that but im rlly not sure.
Step-by-step explanation:
Leanne's list is incorrect and there are 3 different sides a person can choose. So, there are a total of 6 possible ways a person could choose their dinner.
How to determine the number of combinations?The given parameters are:
Main Dish: B, C and P
Sides: A and F
Using the above parameters, the combination of dishes are:
BA, BF, CA, CF, PA and PF
Hence, we can conclude that Leanne list is incorrect
Also, we have:
Dish = 3
Sides = 2
So, the number of dinner to choose is:
Dinner = 3 * 2 = 6
Hence, a person could choose their dinner in 6 ways

if y= 1/5 when x=3, find y when x=4, given that y varies directly with x
Answer:
[tex]y = \frac{4}{15} [/tex]Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
[tex]y \: \: \: \alpha \: \: \: kx[/tex]where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
[tex] \frac{1}{5} = 3k \\ 15k = 1 \\ k = \frac{1}{15} [/tex]So the formula for the variation is
[tex]y = \frac{x}{15} [/tex]From the question
when x = 4
[tex]y = \frac{4}{15} [/tex]Hope this helps you
Point Fis on line segment EG . Given FG = 4 and EF = 9 determine the length EG
Answer:
EG is 13.
Step-by-step explanation:
So we have a line segment EG.
Point F is somewhere on EG.
And we are given that FG is 4 and EF is 9.
Therefore, the length of EG will be the combined lengths of FG and EF. In other words:
[tex]EG=EF+FG[/tex]
Substitute 9 for EF and 4 for FG. Thus: "
[tex]EG=9+4[/tex]
Add:
[tex]EG=13[/tex]
So, the length is EG is 13.
And we're done!
