Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
A runner charted how long it took her to run certain distances here is the information she gathered
Answer:
The answer would be 9.
Step-by-step explanation:
It is going up by 8 each time, so you just have to divide 72 by 8. You will then receive your answer.
(MARKING BRAINLIEST) Kareem cannot decide which of two washing machines to buy. The selling price of each is $390. The first is marked down by 40%. The second is marked down by 10% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer:
See explanation
Step-by-step explanation:
The selling price is $495.
The first washing machine:
- is marked down by 30%
$495 - 100%
$x - 100% - 30% = 70%
Find the value of x:
The second washing machine:
- is marked down by 20% with an additional 10% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.
An investor buys $15,000 worth of stocks. The price of one kind of stock is $35 per share, and the price of the other kind of stock is $45 per share. If 100 shares of the more expensive stock was bought, find the number of shares of the cheaper stock bought.
Answer:
300

In his free time, Gary spends 12 hours per week on the Internet and 8 hours per week playing video games. If Gary has 35 hours of free time per week, approximately what percent of his free time is spent on the Internet and playing video games?
A) 19%
B) 57%
C) 40%
D) 4%
B) 57%
Add up Garys hours spent on internet and games to get total time
12+8=20
To get the percent of time used on internet and games, divide by total time
20/35 = 0.57
Answer: I think it is four percent

four times a number x is at least -12
an inequality is ?
the solution is ?
Answer:
-16
Step-by-step explanation:
im just taking a guess.
x+4>-12
-4 -4
---------------
4's cancel out and -12+-4=-16
Again this is just a guess.
The inequality is 4x ≥ -12 and the solution of this inequality is x ≥ -3.
What are Inequalities?Inequalities are the expressions having two sides connected with inequality symbols. Inequality symbols are <, >, ≤, ≥ and ≠. They may contain one or more variables and constants.
Inequalities which consist of one or more variables with the highest degree of the variables being 1 is called Linear inequalities.
Given that four times a number is at least -12.
Thus the inequality says that 4 multiplied with a number x, which is 4x has values -12 or greater than -12.
So the inequality is 4x ≥ -12.
Solving this,
4x ≥ -12
Dividing both sides by 4, we get,
4x/4 ≥ -12/4
x ≥ -3
Hence the inequality is 4x ≥ -12 and the solution is x ≥ -3.

A jewelry maker is designing a crown. The crown must have at least 45 gems, using only emeralds, rubies, and diamonds. The number of rubies must be 1 less than 3 times the number of emeralds. The number of diamonds must be 4 less than the number of rubies. Which inequality could the jewelry maker use to find the fewest number of emeralds, x, that can be placed on the crown?
Answer:
Step-by-step explanation:
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) ≥ 45 is the answer I got.
The answer to that inequality would be
X ≥ 7 I think

Which would be used to solve this equation? Check all that apply.
subtracting 3 from both sides of the equation
multiplying both sides of the equation by 3
dividing both sides of the equation by 3
substituting 4 for p to check the solution
substituting 36 for p to check the solution
Answer:
1 3 4
Step-by-step explanation:
umm i suck at explaining sorry
Answer: Multiplying both sides of the equation by 3
substituting 36 for p to check the solution
Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.
Then you have 3(p/3) = 3(12)
p = 36 simplify
To check this work, you can substitute 36 for p:
36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

Consider the two functions below. Which one of these functions is linear? What is its equation? Enter any answers to two decimal places.
Answer:
Function A and the equation would be y = 1.6666666666~x + 0
Step-by-step explanation:
A linear function is a function that is a straight line with no change so function B does not fit that description. So than it has to be A
To find the equation you first what to find the slope of the line
ΔY/ΔX = 5/3 = 1.666666666666
Take the slope and multiply it by x to get y
Following are the solution to the given function:
Given:
Function A:
[tex]\bold{x} \ 3 \ 6 \ 9 \ 12 \ 15 \\\\\bold{y} \ 5 \ 10 \ 15 \ 20 \ 25[/tex]
To find:
Find the function=?
Solution:
Function A or equation would've been [tex]\bold{y = 1.6666666666 \sim x + 0}[/tex].The linear equation is a straight line with really no modification, hence function B doesn't suit its description. As a result, it has to be A.You must first calculate the slope of the line to solve this equation.[tex]\bold{\to \frac{\Delta Y}{ \Delta X} = 5/3 = 1.666666666666}[/tex]To get y, take the slope then multiply this by x.
