Rob and two of his friends are digging holes at Rob's house in order to plant some new trees. The holes need to be at least 3 feet deep. So far, Rob's hole is 14/5 feet, Sam's is 2.6 feet, and Tom's is 2 1/8 feet. Who is the closest to being finished?
Answer:
Rob is the closest to being finished.
Step-by-step explanation:
Rob: 14/5 = 2.8 feet
Sam: 2.6 feet
Tom: 2 1/8 = 2.125 feet
2.125 < 2.6 < 2.8
Arwa is playing 'Guess my number'. Arwa says: 'If I add 0.4 to my number, divide the answer by 8, then multiply that answer by 9, I get 0.9.' What is Arwa's number?
Respond to the questions about the first recipe:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

How can you rewrite the number 1 as 10 to a power?
How can you rewrite the number 1 as 2 to a power?
Answer:
To rewrite 1 as 10 to power, you'd write 10^0 (ten to the power of zero).
Any non-zero number with the power of zero equals one. You might be wondering why, so to prove this theorem...
2^1
-----
2^1
Since the numbers are the same on the numerator and denominator, we can agree that the fraction above is equal to 1, yes? It is also equal to...
2^1-1
...because of the quotient rule. And what does 1-1 equal? 0. So you'd get
2^0
This is known as the "zero-exponent rule!"
Hope this helped.

10 x 10 to the power of 9 is how many times greater than 5 times 10 to the power of 3
find the answer using scientific notation
Answer: 2,000,000 or 2*10^6
Step-by-step explanation:
10*10^9 = 10000000000
5*10^3 = 5000
10000000000/5000=2000000
\(10x10^9\) = 10 x 1000000000 = 10,000,000,000
5 x 10^3 = 5 x 10 x 10 x 10 = 5,000
Divide 10 x 10^9 / 5 x 10^3 and the answer is
2 x 10^6

Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

x ≈ 1.88
The cost of the previous year's booths and prizes for Class Fun Day was $504. This year's cost of the prizes and booths increased by 8% from the cost of the previous year. Mark knew that the budget for the class day is $725.76. He claimed that 70% of the money will be spent on prizes and the booths.
Use reasoning to explain how Mark's claim is incorrect. What percent of the money will be spent on the prizes and the booths?

Answer:
The probability of choosing a green shirt is 20%=1/5=.2
Step-by-step explanation:
find the total amount = 10
Find the total of question (probability of choosing green) = 2
set as a fraction:
Numerator = amount needed (2)
Denominator = all things/objects involved (10)
PS*
With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction
ex:
10/2=5=500% (this can't be the answer)
So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

Answer:
25
Step-by-step explanation:
4a +12 -2c + c
4( ) + 12 - 2( ) + ( )
4(4) + 12 - 2(3) + 3
16 + 12 - 6 + 3
28 - 6 + 3
22 + 3
25
Helping in the name of Jesus.
Therefore, 4a + 12 - 2c + c = 25
Step-by-step explanation:a = 4
c = 3
Swap letters for numbers:4a + 12 - 2c + c
(4)(4) + 12 - (2)(3) + 3
16 + 12 - (2)(3) + 3
28 - (2)(3) + 3
28 - 6 + 3
22 + 3 = 25
Draw a conclusion:
Hence your answer is:4a + 12 - 2c + c = 25

Jackson works as a veterinary technician and earns $12.20 per hour. Jackson normally works 40 hours a week. And a normal week, what is his total pay before taxes and other deductions
Answer:
p = 12.20h
30.5 hours
Step-by-step explanation:
Jackson works as a veterinary technician and earns per hour = $12.2
He works in a normal week = 40 hours
Let hours = h and weekly pay = p
p = 12.20h
p = $12.20 × 40
= $488.00
Last week Jackson was ill and missed some work.
His total pay before deduction was $372.10
To find the hours he work the equation will be p = 12.20h
372.10 = 12.20h
372.10/12.20 = h
h= 30.5

Calculate the markdown when the original cost is $87.50 and the markdown is 45%.
Markdown amount:
Retail price:
Answer:
To calculate the markdown amount, we can multiply the original cost ($87.50) by the markdown percentage (45%):
87.50 * 45% = $39.38
The markdown amount is $39.38.
The retail price is the original cost minus the markdown amount. Therefore, the retail price is:
87.50 - 39.38 = $48.12
Therefore, the markdown amount is $39.38 and the retail price is $48.12.
