David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%
Answer:
200/500=2/5
40%
Step-by-step explanation:
If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.
Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500
Then simplify=200/500 divided by 100/100 equals 2/5.
Then to get it to a percentage divide 2 by 5 which equals .40
Then convert to a percentage 40%

75 percent of what number is 150?
StartFraction 75 times 1 Over 150 times 1 EndFraction = StartFraction 75 Over 150 EndFraction
StartFraction 150 times 2 Over 75 times 2 EndFraction = StartFraction 300 Over 150 EndFraction
StartFraction 200 times 2 Over 75 times 2 EndFraction = StartFraction 400 Over 150 EndFraction
StartFraction 75 times 2 Over 100 times 2 EndFraction = StartFraction 150 Over 200 EndFraction
Answer:
200
Step-by-step explanation:
multiplying both sides by 100 and dividing both sides by 75, we have
X = 150 x 100/75
X = 200

PWEEESE HELP FOR BRAINLIEST PLEASEEEEEE
Answer:
4.0541
Step-by-step explanation:
I don't know if this is correct but this is what I got.
You would take the error and divide it by the theoretical value and then multiply that by 100.
7.7 - 7.4 = 0.3
0.3 ÷ 7.4 = 0.04054054
0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%

Paul makes a base monthly salary of $1500. As a vendor, he must sell $19000 worth of items per month. He also makes a 6% commission on all sales beyond the monthly quota. If Paul sold $26600 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
salary=$1500
sell =$19000
commission =6%
he sells of $26600
commission amount =6% of[26600-19000]=$456
total salary =$1500+456=$1956 is the required salary.
The total salary for the month including base salary and commission to the nearest dollar is $1956.
It is required to find total salary for the month.
What is arithmetic?The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications
Given that:
salary=$1500
sell =$19000
commission =6%
he sells of $26600
6% Commission for every sales beyond the quota commission amount =6% of[26600-19000]=$456
So
Base Salary + 6% Commission,
∴Total salary =$1500+456=$1956 is the required salary.
Here, the total salary for the month including base salary and commission to the nearest dollar is $1956.

Bekkah's savings account earns 2.75% interest per year.
If she put $12,500 into the savings account, how much interest is earned in a year, in dollars?
Answer:
343.75 dollars
Step-by-step explanation:
First I like to solve for the value of 1% which is 125 then we solve for .10% which is 12.5 then we solve for .01% which is 1.25 I find this helpful because now we have the unit amount for each percent we use in this equation now to multiply we have .05 percent so we take our 1.25 value for .01 percent and multiply by 5 which give us 6.25 then we do .7% we take our .1 percent value and multiply 12.5 x 7 give us 87.5 then we do the 2% we take our 1 percent value and multiply by 2 125 x 2 give us 250 now we add it all together 250+87.5+6.25 = 343.75 I hope this help you out :)
Ian needs to find the area of the shaded region shown below. Which statements can he use to find the answer? Select three options.
A circle with diameter 11 feet. Three-quarters of the circle is shaded.
The radius is 5.5 feet.
The area of the whole circle is A = (5.5) squared pi.
The area of the whole circle is A = (11) squared pi.
The area of the shaded region can be found by multiplying the area of the whole circle by three-fourths as in A = three-fourths (pi times r squared).
The area of the shaded region can be found by multiplying the area of the whole circle by two-thirds as in A = two-thirds (pi times r squared).

Don't try to cheat the system by asking so many questions in 1 block
Question 1. if 3 flowers = 4 inches, and she has a 3 foot long row to plant flowers, then we need to see how many inches the row is.
1 foot = 12 inches
12 inches x 3 = 36 inches, or 3 feet.
Now we need to divide.
36 divided by 4 = 9.
So now we know that Mrs. Ryan can plant x amount of flowers 9 times. This makes the answer easier to find.
To find the answer, we need to simply multiply 3 and 9.
3 x 9 = 27.
Your answer would be Mrs. Ryan planted 27 flowers.
Question 2. this is simple. Just multiply 5 and 3.
5 x 3 = 15.
Your answer would be Mrs. murphy bought 15 feet of fabric.
Question 3. This is simple...Just multiply 4.3 x 100, or move the decimal over to the right twice and put a 0 where theres an empty space.
4.3 x 100 = 430
Your answer is the line is 430 centimeters wide.
Question 4. This is simple, just multiply 2.9 x 100 or move the decimal over to the right twice and put a 0 where there's an empty space.
2.9 x 100 = 290
Your answer is The book is 290 milliliters wide.
Question 5. This is also very simple. This time we add a decimal twice to the left. Put the decimal next to the 0 in 210.
210.
21.0
2.10
Your answer would be the bookshelf is 2.1 meters tall.
Question 6. This is, again, simple... Just multiply 3 and 1.61.
3 x 1.61 = 4.83
Your answer would be Connor ran 4.83 kilometers.
Question 7. This is simple, again... Just multiply 13 and 2.54.
2.54 x 13 = 33.02
Your answer would be c, 33.02 cm.
Explain how to solve the equation and how to check the solution.
40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

A cake recipe requires flour and sugar in a ratio of 4 to 3. Which table has been generated using this ratio?
Answer:
The third table
Step-by-step explanation:
A ratio is a relationship that illustrates how many times one number contains another. For example, the ratio of 4:3 means there is 4 cups of flour for every 3 cups of sugar. The third table is the only one that increases proportionate to the ratio. This can be seen because when 4 is multiplied by 3 to get 12, so is 3 to get 9. This pattern continues, with both amounts being multiplied by the same number.
