Step-by-step explanation:
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

(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.

A farmer had 22.75 bushels of corn. He sold 12 2/5 bushels at the market. His three friends bought the remaining bushels of corn. If each person bought the same amount, how many bushels did each friend purchase?
Answer:
Each friend bought 3.45 bushels of corn.
Step-by-step explanation:
12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

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

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.
