Ricardo’s goal was to run 40 laps. At the end of the week, he ran 125% of his goal. How many laps is that?
Answer: He ran 50 laps.
Step-by-step explanation:
40 x 1.25 = 50
Answer:
50
Step-by-step explanation:
40/1 = 100/1
125% = 100/100 + 25/100
25% of 40 = 10
so you have the 40 laps which equal 100% and you also have 25 percent of the from the 125% and 25 percent of 40 is 10 so the answer is 40 plus 10 wich is 50
Hope this helps
Find the circumference of the circle. Round your answer to the nearest hundredth. Use 3.14 or 227 for π. the circle is 3
Answer:
18.84 ft
Step-by-step explanation:
The formula for the circumference of a circle is to multiply the radius (The line that's 3 ft in this case) by 2 and then multiply by π, which the problem says to substitute 3.14 in. Since the radius of this circle is 3, we multiply 2 by 3 and then multiply that by 3.14 to find our circumference. 3 * 2 = 6 and 6 * 3.14 = 18.84. The circumference of this circle is 18.84 ft.
Answer:
18.84 ft

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.
Answer:
The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3) x 3.14 x 9^2 x 16
Calculating this expression gives us:
V = 1810.08 cubic inches
Rounding to the nearest hundredth gives us:
V ≈ 1810.08 cubic inches (rounded to two decimal places)
Therefore, the volume of the cone is approximately 1810.08 cubic inches.
Answer:
1363.04
Step-by-step explanation:
V = (1/3) * 3.14 * 9^2 * 16
Simplifying:
V ≈ 1363.04 cubic inches

A coffee storage bin contains 1500 grams of coffee beans. To make a cup of coffee, grams of coffee beans are removed.
The equation _______
models the relationship between the quantity of coffee beans removed, , and the quantity of coffee beans remaining in the storage bin, .
q = 1500 + n
q = 1500 - n
q = 1500n
Answer:
Step-by-step explanation:
When we remove coffee beans, then the quantity of beans reduces. So, we have to subtract to find the remaining coffee beans.
q = 1500 - n

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

84 because PEMDAS(parenthesis/Exponents/Multiply/Divide/Add/Subtact) says you do parenthesis first. So you add 9 and 3 to get 12. The you do 12*7 to get 84.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

When you learned to add decimals, you saw that lining up the decimal point in the addends is really important. Why do you think it is not necessary to line up the decimal points in the two factors when multiplying decimals?
Answer in 2 complete sentences.
Answer:
It is not necessary to line up decimals while multiplying because you count the decimals instead of bringing them down. Plus lining up decimals while adding can overcomplicate the problem with too many zeros.

The area of a rectangle is 2x^2-7x-15. Determine binomials that represent the length and the width if this triangle
Answer:
\((x-5),(2x+3)\)
Step-by-step explanation:
Given: area of a rectangle is \(2x^2-7x-15\)
To find: binomials that represent the length and the width of the rectangle
Solution:
A polynomial that consists of two terms is known as binomial.
\(2x^2-7x-15=2x^2-10x+3x-15\\=2x(x-5)+3(x-5)\\=(2x+3)(x-5)\)
Also, area of rectangle is length × breadth
So, length × breadth = \((2x+3)(x-5)\)
So, length = 2x+3, breadth = x-5 or length = x-5, breadth = 2x+3

88. Referring to the figure, Mrs. Hawkins took four slips of paper
and wrote a different student's name on each. Two of the names were
boys and two girls. She put the four slips of paper in a bag and said
she is going to draw two slips out. She then drew the tree diagram
to show the different outcomes that are possible. "B" represents a
boy's name and "G" represents a girl's name. What is the theoretical
probability that the teacher draws two names that are the same sex?
a. 1/6 c. 1/3
b. 2/3 d. 1/12
Answer:
a. 1/6
Step-by-step explanation:
I just counted the 12 outcomes and the 2 same sex possibilities, which would turn to 2/12, and then simplified it into 1/6. I hope this is right, I am very sorry if it isn't.
