Answer:
0
Step-by-step explanation:
To find the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
= ( 4-4)/( 5 - -3)
= 0/ ( 5+3)
= 0/8

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%.
What is the Value of X?
Answer:
x = 27
Step-by-step explanation:
4x+7 = 5(x-4)
4x + 7 = 5*x + 5*-4
4x + 7 = 5x - 20
7 + 20 = 5x - 4x
27 = x
Check:
4*27 + 7 = 5*(27-4)
108 + 7 = 5 * 23 = 115
Answer: x = 27
Step-by-step explanation:
These angles are congruent to each other so we well put an equal sign in between the two degrees.
Distribute the 5 by multiplying x and the -4 by 5 to get, 5x - 20
4x + 7 = 5x - 20
add 20 to the 7
subtract 4x from the 5x
27 = 1x
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
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)
7. Da'Quan is reading a 532-page book for English. His teacher says that each student must have read at least half of the book by the end of the 1st week. If Da'Quan reads each of the 7 nights, write and solve an inequality to represent the number of pages he should read each night to meet the teacher's requirements.
Answer: x > 38
Step-by-step explanation:
Easy
Da'Quan must read more than 38 pages each night.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
The Number of pages in the Quran = 532
The Number of nights in a week = 7
Target is to read more than half by the end of the first week
In other to meet up, Let number of pages to be read per night = r
Hence, the equality goes ;
Pages read per night × 7 > pages of the Quran / 2
7× r > 532 / 2
7r > 266
r > 266/7
r > 38
Hence, Da'Quan must read more than 38 pages each night.

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:

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
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.

C (x) = x^2 - 10x+27
Answer:
C(x) = (x-5)^2 + 2
................
Answer
[tex]5+2\sqrt{x} 13=12.211[/tex] or 5−2 this is where the square root would go 13=−2.211
Step-by-step explanation:
1.1 Factoring x2-10x-27
The first term is, x2 its coefficient is 1 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is -27
Step-1 : Multiply the coefficient of the first term by the constant 1 • -27 = -27
Step-2 : Find two factors of -27 whose sum equals the coefficient of the middle term, which is -10 .
-27 + 1 = -26
-9 + 3 = -6
-3 + 9 = 6
-1 + 27 = 26
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
2.1 Find the Vertex of y = x2-10x-27
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 5.0000
Plugging into the parabola formula 5.0000 for x we can calculate the y -coordinate :
y = 1.0 * 5.00 * 5.00 - 10.0 * 5.00 - 27.0
or y = -52.000

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.

The correct answer is "B"
Step-by-step explanation:
m=-1/4
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.

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.
