Answer:
(5^2)(n^4)
Step-by-step explanation:
since the exponents have common bases of 5, we can think of it like 4-2, since the 5^2 being in the denominator makes it negative, and since n^4 is left unaffected, we are left over with (5^2)(n^4)
results for a dvd has a radius of 12cm. what is the diameter and circumference of the dvd? round to the nearest hundredth
Answer:
Diameter: 24 Circumference: 75.36
Step-by-step explanation:
(equation for finding circumference: 2(3.14)r or 3.14d)
2(3.14) x 12 = approximately 75 or 75.36
Diameter = r2
12(2) = 24

Step-by-step explanation:
A roll of ribbon was 12 meters long. Diego cut 9 pieces of ribbon that were 0.4 meters each to tie some presents. He then used the remaining ribbon to make some wreaths. Each wreath required 0.6 meter.
How many meters of ribbon were available for making wreaths?
_____ meters
How many wreaths could Diego make with the available ribbon?
_______wreaths
Answer: 8.4; 14.
Step-by-step explanation:
To find how much ribbon we used to tie presents, we need to multiply 9 and 0.4.
9 x 0.4 = 3.6.
Diego used 3.6 meters of yard to tie some presents. We can subtract that from 12 to find how much ribbon we have left.
12 - 3.6 = 8.4.
We have 8.4 meters of ribbon to make wreaths.
Now we have to find how many wreaths we can make wiht 8.4 meters of ribbon. We know that each wreath needs 0.6, so we should divide 8.4 by 0.6 to find how many wreaths we can make.
8.4 ÷ 0.6 = 14.
Therefore, we can make 14 wreaths with the 8.4 meters of leftover ribbon.
(Part A's answer is 8.4, and Part B's answer is 14)

A dinner cost $28.50 which included a 15% tip. How much was the tip?
Answer: $4.28
Tip: $4.275 = $4.28
Step-by-step explanation:
Use the formula: Tip = Tip% x Bill Total
In this case, the tip is 15% and the total bill is $28.50.
15% = 0.15
28.50 x 0.15 = 4.275
Round 4.275 to the hundredths, which equals 4.27
Answer: Tip: $4.275 = $4.28
Step-by-step explanation:
Use the formula: Tip = Tip% x Bill Total
In this case, the tip is 15% and the total bill is $28.50.
15% = 0.15
28.50 x 0.15 = 4.275
Round 4.275 to the hundredths, which equals 4.27
Answer:
$4.28
Step-by-step explanation:
15%= 0.15
0.15*28.50= 4.275
Simplified: $4.28

is cooking popcorn on a stove convection, radiation or conduction?
Cooking the popcorn on a stove is the transfer of energy in the form conduction.
Heat Energy transfers from the flame to the popcorn through the utensil which uses the mode of CONDUCTION.
Answer:
Conduction
Explanation:
The heat from the pan transfers directly to the oil. The heat from the oil transfers directly to the popcorn kernels. When the kernels reach 100°C, the liquid water inside each kernel turns into a gas (steam) and expands, making the kernel “pop.”

Describe how to write an equation from a table of values using a graph. No there is not a graph that is all I was given for the question.
Answer:
Look that the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.
An example is (-3,2), if you see the point (-3,2) on your graph, plug in -3 for the x value and 2 for the y value (don't include this example into your response - it was just for you to see what I mean)
Answer:
just look at the step by step
Step-by-step explanation:
To Write an equation for a table using a graph each point on the coordinate plane. Draw a line through the plotted points. Then,find the y intercept(where the line crosses the Y-axis.) Figure out from the graph what the rise and the run are and calculate the slope.Then,put the equation in y=mx+ b format.
could you help me with this
Answer:
The expression you provided involves a limit, a summation, and variables. To provide a clear and concise answer, I will break down the components of the expression and explain their meaning.
1. lim (0 to 100): This notation represents the limit as a variable approaches a certain value. In this case, the variable is not specified, so I will assume it represents the value of M.
2. Σ (k=1 to n): This symbol represents a summation, where the variable k takes on values from 1 to n. The value of n is not specified in the expression you provided, so I cannot calculate the exact summation.
3. In n: I'm not sure what "In n" refers to in this context. It could be a typo or an incorrect notation. Can you please clarify or provide more information?
Based on the information provided, I can explain how to evaluate a general expression involving a limit and a summation.
To evaluate the expression, follow these steps:
1. Determine the values for M and n. These values may be provided in the problem or given as part of the context.
2. Plug in the values of M and n into the expression.
3. Evaluate the summation by substituting k with the values from 1 to n and summing up the results.
4. Finally, take the limit as M approaches the specified value, if applicable.
If you provide more information or clarify the meaning of "In n," I can provide a more specific answer.

Dom Grady has completed 21 out of 25 passes for his football team. What percentage of his total passes has he completed? Explain and support your answer. Show ALL steps.
(I'll give you five stars if you do this right, thank you!!)
Answer:
84%
Step-by-step explanation:
Completed passes: 21
total: 25
fraction: 21/25
21/25 x100
= 84
He has completed 84% of passes.
Answer: 84%
Step-by-step explanation:
1. Convert each number to 100% to make it easier to work out.
2. Multiply 25 x 4 to get to 100, and 21 x 4.
3. 21 x 4=84.
4. So, Grady had completed 84% of the passes.

Answer:
1. 5lb bag is cheaper
2. 6 mpm (minutes per miles)
3. Brycen
4. 18 mpm faster
5. 32 total shapes
6. 75
7. not enough info

10. 2
Step-by-step explanation:
3lb=$3.54=1lb=$1.18
5lb=$5.85=1lb=$0.85
12 minutes/2 miles=6 mpm
24 minutes/1 mile=24 mpm
24-6=18 mpm faster
25% of 100= 4
4×8=32
60% of 80= 75
process of elimination:
24.5 is less than 35 so no
50×.7=35, total miles is 50

Anita incorrectly wrote the equation z = w – 18 to describe the pattern in the table.
Choose the best description of Anita’s error.
The best description for Anita's error is z = 9w.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an expression.
We have,
From the table,
The pattern that describes the table.
Let the pattern be z = mw + c
Now,
(3, 27) and (5, 45)
m = (45 - 27) / (5 - 3) = 18/2 = 9
Now,
(3, 27) = (w, z)
27 = 9 x 3 + c
27 - 27 = c
c = 0
Now,
The pattern for the table.
z = 9w
Thus,
The patter for the table is z = 9w.
