what is 4+n/3=2
the slash is a fraction
Answer:
n = -6
Step-by-step explanation:
4 + [tex]\frac{n}{3}[/tex] = 2
[tex]\frac{n}{3}[/tex] = -2
n = -6
Answer:
n = -6
Step-by-step explanation:
4 + n/3 = 2
subtract 4 from both sides
n/3 = 2 -4
n/3 = -2
multiply both sides by 3
n = 3(-2)
n = -6
2. If the radius of a body-centered cubic unit cell is 2.55 x 10-8 cm, what is the length of the edge in pm
Step-by-step explanation:
Given that,
The radius of a bcc unit cell is, [tex]r=2.55\times 10^{-8}\ cm[/tex]
We need to find the length of the edge in pm.
We know that,
For a bcc unit cell, the relation between the radius and the length of the edge is given by :
Edge length,
[tex]a=\dfrac{4r}{\sqrt{3} }\\\\a=\dfrac{4\times 2.55\times 10^{-8}}{\sqrt{3} }\\\\a=5.88\times 10^{-8}\ cm[/tex]
Hence, this is the required soolution.

Answer:
i think it is a? im not completly sure ;/
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
We have to go backwards to find the answer. The X is being subtracted, so we add.
1) Add 5 to 103 (We get 103 because of the angle - I figured it was greater than 90 because the other two angles are smaller than 90. 103 was the last option so I tried that and I got 27 in the end.)
2) Divide by 4 - because we were multiplying X by 4.
What is the solution to the system of equations?
y = -5x + 3
y = 1
9514 1404 393
Answer:
(x, y) = (2/5, 1)
Step-by-step explanation:
Substitute for y and solve for x.
1 = -5x +3
-2 = -5x . . . . . . subtract 3
2/5 = x . . . . . . divide by -5
The solution is (x, y) = (2/5, 1).

Any ideas to what the answer is?
Answer:
The value of y = 15
Step-by-step explanation:
Given the sides
2y+255y-20As we know that a parallelogram is a quadrilateral whose opposite sides are parallel.Thus, the equation becomes
5y-20=2y+25
5y-2y = 25+20
3y = 45
y = 15
Thus, the value of y = 15
Select all instances in which the variable described is binomial.
a. A coin flip has two outcomes: heads or tails. The probability of each outcome is 0.50. The random variable represents the total number of flips required to get tails.
b. A quality check on a particular product must meet five guidelines. All products are made in the same factory under the same conditions. The random variable represents the total number of products out of 35 tested that pass inspection.
c. Based on the parents' genetics, each of 6 children from a particular pair of parents has a 0.30 probability of having blue eyes. The random variable represents the total number of children from this pair of parents with blue eyes.
d. There are two banking options for customers of ABC Bank, checking or savings. The random variable represents the total number out of 567 customers with a checking account.
e. The probability of drawing an ace in a standard deck of cards is 0.08. Seven cards are drawn without replacement. The random variable represents the total number of ace cards observed.
Answer: a. , c. , d., e.
Step-by-step explanation:
A variable that counts how many times a certain event occurs in a particular number of trials is known as binomial random variable.
For each trial, there exist only two outcomes .
The probability of for each event is the same on each trial.
a. Event has two outcomes with same probability as 0.50, therefore the random variable represents the total number of flips required to get tails is a binomial random variable.
b. Total guidelines are 5.
Here total outcomes are not 2 , it does not meet with the conditions of binomial.
c. The random variable represents the total number of children from this pair of parents with blue eyes has two outcomes (where has or not.)
also, the probability of having blue eyes is same in each trial, so it represents binomial random variable.
d. The random variable represents the total number out of 567 customers with a checking account has two outcomes (checking or savings).
So, it represents binomial random variable.
e. The random variable represents the total number of ace cards observed has two outcomes ( ace or not ace).
So it represents the binomial random variable.
Which one has a greater value, , -7 + (-7) or -7 - (-7)? Explain your answer. GIVING BRAINLIEST!!! ❤️
Answer:
-7 - (-7)
Step-by-step explanation:
The correct answer is not -7 + (-7) because adding a negative is basically subtracting. So -7 + (-7) is -14. However, subtracting a negative is basically adding, so -7 - (-7) is 0.
0 > -14
Answer:
-7 - (-7) is the greater number
Step-by-step explanation:
-7 + (-7) = -14
-7 - (-7) = 0
Zero is always greater than a negative number

A 14 gram sample of a substance that's
used to preserve fruit and vegetables has
a k-value of 0.1095.
-kt
N = Noe
No = initial mass (at time t = 0)
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days
Find half-life in days. Round to nearest tenth
Answer:
The half-life in days is 6.3 days
Step-by-step explanation:
Here, we want to get the half-life
From what we have in the question, we can see that we have a first order decay relation
For a first order decay relation;
t1/2 = ln 2/k
That will be;
t1/2 = ln2/0.1095
t1/2 = 6.33
To the nearest tenth, this is 6.3 days

How many solutions does the system of equations below have?
y= 3x + 4
2y -8 = 6x
Answer:
infinitely many solutions (infinite solutions)
Step-by-step explanation:
2y - 8 = 6x
+8 +8
-------------------------------
2y = 6x + 8
[tex]\frac{2y}{2}[/tex] = [tex]\frac{6x}{2}[/tex] + [tex]\frac{8}{2}[/tex]
-------------------------------
y = 3x + 4
Because 3x + 4 = 3x + 4, there are infinitely many solutions to this system of equations. This is because they're the exact same equations. Any substitution for x will give you a true statement to y when compared to the other equation.

{5x−2y=43x−4y=−6 What is the answer
Answer:
(2,3)
Step-by-step explanation:
5x - 2y = 4 (1)
3x - 4y = -4 (2)
Multiply equation 1 by 2
10x - 4y = 8 Subtract 2 from the equation on this line
3x -4y = - 6
7x = 14 Divide by 7
x = 14/7
x = 2
5x - 2y = 4
5*2 - 2y = 4
10 - 2y = 4
-2y = 4-10
-2y = - 6
y = -6/-2
y = 3

which numbers that round to 2.35 when rounded to nearest hundredth
2.349
2.352
2.354
2.359
Answer:
the second one.
Step-by-step explanation:
The numbers which can be rounded to 2.35 as its nearest hundredths are:
- 2.349
- 2.352
- 2.354
Given,
2.349
2.352
2.354
2.359
We need to see which after rounding to the nearest hundredths gives 2.35
What is the place value of a decimal number?234.567
2 - hundreds place value
3 - tens
4 - ones
5 - tenths
6 - hundredths
7 - thousandths
We have,
- 2.349
Here
4 is in hundredths place value.
If we round 49 to its nearest hundredths we get,
49 = 490
we can round to either 400 or 500
Since 490 is greater than 449 we round to 500
2.349 is rounded to 2.3500 or 2.35
-2.352
52 = 520 can be rounded to either 500 or 600.
Since 520 is smaller than 549 we round it to 500
2.352 is rounded to 2.3500 or 2.35
- 2.354
Similarly, 54 = 540 is less than 549 so we will round to 500.
2.354 is rounded to 2.3500 or 2.35
-2.359
We can round 590 to 500 or 600
Since 590 is greater than 549 we will round it to 600.
2.359 is rounded to 2.3600 or 2.36.
Thus the numbers which can be rounded to 2.35 as its nearest hundredths are:
- 2.349
- 2.352
- 2.354

Elwin is attempting to read a 480 page book in 28 days. He reads the first 60 pages in 4 days. At this rate, will he finish the book in time? Show your work and/or explain your reasoning.
Answer : No, he won't
Step-by-step explanation:
Given
Target = 480 pages in 28 days
Rate = 60 pages in 4 days
Required:
Determine if he'll reach his target
The rate can be expressed using:
Rate = pages/days
So, we have:
Rate = 60 pages/ 4 days
Multiply the fraction by : that number are on pdf
This can be interpreted as: 420 pages in 28 days
And his target is 480 pages in 28 days
Hence, he wont finish the book at that rate
(hoped it helped)
Answer:
if every 4 days it is 60 days it would have to be
60 pages 4 days
120 pages 8 days
180 pages 12 days
240 pages 16 days
300 pages 20 days
360 pages 24 days
