Frank said that 8*10^4 is 320 do you agree or disagree
Answer:
I disagree with Frank
Answer:
Disagree
Step-by-step explanation:
Remember to follow the order of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
In this case, the first step should be to solve for [tex]10^{4}[/tex].
[tex]10^4 = 10 * 10 * 10 * 10 = 10,000[/tex]
Next, multiply by 8:
[tex]10,000 * 8 = 80,000[/tex]
80,000 is your answer, so I disagree.

Carol is cross-country skiing. The table shows the distance she traveled after various numbers of minutes. What is the rate of change? Distance Carol Traveled while Cross-Country Skiing Minutes Distance Traveled (miles) 2 StartFraction 1 Over 6 Endfraction 3 StartFraction 17 Over 48 EndFraction 4 StartFraction 13 Over 24 EndFraction 5 StartFraction 35 Over 48 EndFraction 6 StartFraction 11 Over 12 EndFraction
Answer:
3/16 miles/minute
Step-by-step explanation:
A rate of change describes how an output quantity changes relative to the change in the input quantity.
Points given:
Input Output
2 1/6
3 17/48
4 13/24
5 35/48
6 11/12
Here input values describe the time in minutes from 2 to 6 and output values describe the distance in miles from 1/6 to 11/12
Calculating the rate of change using the first two pairs of input-output values
Relative change = change in distance/change in time(17/48 - 1/6)/(3-2) = (17/48 - 8/48) /1 = 9/48 = 3/16 miles/minuteWe will get the same result if we take any other ordered pair of input and output values.
Answer:
it is 3/16 miles per minute

Hope this help!
have a nice day!
Answer:
B
Step-by-step explanation:
So we have the equation:
[tex]\frac{3m-3}{5}=\frac{2m-1}{2}[/tex]
First, let's get rid of the fractions. Multiply both sides by the LCM of 5 and 2, which is 10:
[tex]10(\frac{3m-3}{5})=10(\frac{2m-1}{2})[/tex]
On the left, the 10 gets reduced to 2. On the right, the 10 gets reduced to 5. Thus:
[tex]2(3m-3)=5(2m-1)[/tex]
Distribute:
[tex]6m-6=10m-5[/tex]
Subtract 6m from both sides:
[tex]-6=4m-5[/tex]
Add 5 to both sides:
[tex]-1=4m[/tex]
Divide both sides by 4:
[tex]m=-\frac{1}{4}[/tex]
And we're done!
The answer is B.
Help please!!! Thxxxxxx
Answer:
40 degrees
Step-by-step explanation:
Angle ACO = 80 ( 180 - 100)
Angle CAO = 60 (180 - 120)
Angle AOC = 40 (180 - 80 - 60) (TOTAL DEGREES OF A TRIANGLE IS 180)
HELP PLEASE I'LL GIVE 25 POINTS!!! A triangular prism of cheese is measured and found to be 2.0 inches tall. The edges of its base are 9.0, 9.0, and 4.0 inches long. Several congruent prisms are to be arranged around a common 2.0- inch segment, as shown. How many prisms can be accommodated? What is their total volume? PLEASE INCLUDE WORK
pleaseeeeeeeeeeee SOMEONE HELPME BRO
Answer:
14 prisms can be accomodated
Their total volume would be 504 in³
Step-by-step explanation:
First, we have to figure out the angle at the vertex. For that, we need the Law of cosines. c²=a²+b²-2ab*cos(c)
4²=9²+9²-2(9)(9)cos(c)
16=81+81-162cos(c)
16-81-81=-162cos(c)
-142=-162cos(c)
-142/-162=cos(c)
.9=cos(c)
use the inverse
cos^-1(.9)=c
25.8=c
Now that we know c=25.8, we can figure out how many cheese wedges there would be in the circle.
36÷25.8=14
Now we figure out volume.
1/2(9)(4)(2)=36 in³
The total volume would be
14x36=504 in³
Right and solve an equation to find the number N
Six times the sum of a number and 15 is -42
Answer:
N=-22
Step-by-step explanation:
We first highlight all the information that is important and make an equation based on that. From that, we get 6(N+15)=-42. From there, we divide both sides by 6 to get N+15=-7. We subtract 15 from both sides to get N =-22, which is our answer.

donna spent a total of $80 at the grocery store of this amount she spent $64 on fruit what percentage of the total did she spend onf ruit
Answer:
Donna spent 80% on fruit.
Step-by-step explanation:
First, we know that she spent $64 on fruit. We also know that she spent a total of $80. Then, we take 64/80. This gives us 0.8. Move the decimal two to the right and you have the percentage, 80%.
A rectangle has length 2x+3 and width 7x+9. Write a polynomial in standard form that represents the perimeter of the rectangle. You MUST combine like terms.
Answer:
18x+21
Step-by-step explanation:
First multiply each equation by 2 since there is 2 sides for both the length and width.
2(2x+3) 2(7x+9)
4x+3 14x+18
Then combine like terms
4x+14x 3+18
18x 21
Please Help!!! What is the end behavior of function h? h(x)=2(x-3)^2 As x approaches negative infinity, approaches negative infinity, positive infinity, or a constant . As x approaches positive infinity, approaches negative infinity, positive infinity, or a constant .
Answer:
Step-by-step explanation:
Function to be graphed is,
h(x) = 2(x - 3)²
Function 'h' is a quadratic function.
Since, the coefficient of the leading term (term with the highest power) is positive, parabola will open upwards.
Both the ends of the parabola will be upwards (towards positive infinity).
As x approaches to negative infinity, h(x) approaches to positive infinity.
As x approaches to positive infinity, h(x) approaches to positive infinity.
A) As x approaches negative infinity, h(x) approaches positive infinity.
B ) As x approaches positive infinity, h(x) approaches positive infinity.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Function to be graphed is,
h(x) = 2(x - 3)²
Function 'h' is a quadratic function.
Since the coefficient of the leading term (a term with the highest power) is positive, the parabola will open upwards.
Both the ends of the parabola will be upwards (towards positive infinity).
Therefore As x approaches negative infinity, h(x) approaches to positive infinity. As x approaches positive infinity, h(x) approaches to positive infinity.

Hannah is asked to convert the number 0.00000305 to scientific notation. Her answer is 3.05 x 106.
Which statement best describes her answer?
Answer:
Hanna converted the number:
0.00000305
to:
3.05x10^6.
Now, when we have:
Ax10^n
This will "move" the value of A n times to the left, adding zeros when the decimals of A run over.
if we have
Ax10^-n
This will move A n times to the right.
Then the number:
3.05x10^6 = 3050000
This is clearly not the number that Hannah wanted to write.
The problem is that the exponent should be negative, if we have instead:
3.05x10^-6
We move our number 6 times to the right, adding zeros when necessary.
3.05x10^-6 = 0.00000305.
So Hannah is incorrect, she should wrote 0.00000305 = 3.05x10^-6
Answer: D. Hannah is not correct because the exponent should be -6.

Atoms are made up of electrons, protons and neutrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. The oxygen atom has 8 electrons and 8 neutrons. How many protons must it have to have 0 charge?
Answer:
Protons and neutrons each count for one AMU, and the electron counts for zero AMU. So, if the atomic mass of oxygen is 16, that means we have a total of 16 protons and neutrons. 16 total protons and neutrons minus 8 protons leaves us with 8 neutrons.
Two people share £700 in the ratio 3:2
Answer:
420:280
Step-by-step explanation:
first you add 3:2 up which comes to 5.
700 divided by 5 = 140.
3:2 means that 3 will get 3 lots of 140 and 2 will get 2 lots of 140.
3x140= 420.
2x140= 280
the ratio is 420:280
Latrell runs 5 miles during each track practice. How many track practices would it take for Latrell to run 25 miles?
Step-by-step explanation:
400 meters is standard lap distance for a race track. 2 x 50 meters is lap distance in International pools. A lap of 440 yards is 1/4 mile. So 4 laps/mile.
Answer:
It would take her 5 track practices to run 25 miles because she runs 5 miles each practice. We can divide 25 by 5 which gives us 5. So it would take 5 track practices for Latrell to run 25 miles. Hope this helps.

Elena works at the ticket booth of a local play house. On the opening night of the play, tickets are $10 each. The playhouse has already sold $300 worth of tickets during a presale. How many tickets must Elena sell In order for the play house to make a total of $900?
Answer:
Elena needs to sell 60 tickets
Answer:
Elena must sell 90 tickets to earn $900
Step-by-step explanation:
Divide the total money needed by how much each ticket costs:
900 ÷ 10 = 90
If you're talking about how many more tickets are needed:
Subtract the total tickets needed by how many tickets Elena already sold
90 - 30 = 60 more tickets needed
