Answer:
n/4-9 +3
Step-by-step explanation:
to answer this question we have to analyze the information given.
The quotient of a number means the result of the division of 2 numbers.
In this case the numbers are: a number (n) and 4 . n/4
Nine less than that quotient means we have to subtract 9 to the quotient.
n/4-9
Increase by three: we simply have to add 3
n/4-9 +3

The points (-5, r) and (2, 3) lie on a line with slope 2. Find the missing coordinate r.
Answer:
Step-by-step explanation:
I will use the formula for finding the slope of a line.
rise/run = y2 - y1/x2 - x1
3 - r/2 - -5
We will subtract 2 from -5. 2 - -5 = 7
Since the slope is 2, and 2 - -5 = 7, then 3 - r = 7x2 = 14.
3 - 14 = -11
r = -11

a + c = 30
12a + 8c = 280
Answer:
a=10 and c=20
Step-by-step explanation:
This is a system of equations. I will solve using the substitution method.
a+c=30
12a+8c=280
Solving for a:
a+c-c=30-c
a=30-c
Substituting a into the second equation:
12(30-c)+8c=280
360-12c+8c=280
360-4c=280
-4c=-80
c=20
Substituting into the original equation:
a+20=30
a+20-20=30-20
a=10
To prove this answer is correct, I will plug the solutions back in to the original equation.
a+c=30
10+20=30
30=30, True
12a+8c=280
12*10+8*20=280
120+160=280
280=280, True
Therefore, a=10 and c=20.

1 yd² of soil containing 30% clay was mixed into 2 yd of soil containing 45% clay. What is the clay content of the mixture?
Answer:
105% ?
Step-by-step explanation:
I'm not entirely sure if the 1 yard 'squared' is considered in the 30% but assuming it's not ... 1yd =30% 1yd^2=60% and 2yd=45% so 60%+45%=100%

t=Time=5 years
Hence:
I= ($400×0.035 x 5)
I= $70

Radically reduce square root of 243
Answer: 9sqrt(3)
Step-by-step explanation:
First, we can prime factorize 243.
243 = 3^5
Therefore we are computing the square root of 3^5
3^5 = 3^4 * 3^1; 3^4 = (3^2)^2
Therefore, sqrt(3^5) = sqrt((3^2)^2))*3^1)
= 3^2*sqrt(3)
= 9sqrt(3)
given that (x-2) is a factor of (x³-8) ,what is the other factor?
Answer:
[tex]x^2+2x+4[/tex]
Step-by-step explanation:
This expression can also be written as a difference of cubes:
[tex]x^3-2^3[/tex]
A important formula to remember is:
[tex]a^3-b^3=(a-b)(a^2+ab+b^2)[/tex]
We can use this to factor this expression:
[tex]x^3-2^3=(x-2)(x^2+2x+4)[/tex]
Therefore the other factor is:

Round 0.3391 to
the thousandths place.
Answer:
.3390 or just .339
Step-by-step explanation:
Solve ABC where ∠C = 90°, a = 15 cm, and b = 7 cm.
Answer:
c ≈ 16.55cm ; ∠A = 65 degrees ; ∠B = 25 degrees
Step-by-step explanation:
Because of the Pythagorean theorem, we can solve for c.
This theorem states: a^2 + b^2 = c^2
Since there can only be 180 degrees in a triangle, angle C must be our largest angle. This means that side c is our hypotenuse (the longest side).
Using all of this information, we can say that 15^2 + 7^2 = c^2.
Simplifying that equation, we get that 274 = c^2.
In order to find c, we must square root both sides, and we find that c is about 16.55 cm long.
Using SOHCAHTOA, we know that the tan(∠B)=[tex]\frac{7}{15}[/tex]. Therefore, the arctan ([tex]\frac{7}{15}[/tex]) = ∠B.
Once you find that ∠B is about 25 degrees, you can add ∠B and ∠C together and subtract that from 180 to find ∠A.
∠A = 65 degrees.

find a common factor between 6 and 8, thats 24.
(multiply the first fraction by 4, second by 3, both numerator and denominator)
Becomes:
[tex]\frac{20}{24} - \frac{9}{24}[/tex]
Then subtract the numerators, keeping the denominators the same:
20 - 9 = 11;
So the answer is:

Answer:
distributive propertymultiplicative identity elementassociative property of additionStep-by-step explanation:
1.The distributive property of multiplication over addition tells you a factor outside parentheses will multiply each term inside parentheses. That fact is used to expand the given expression. In general, ...
a(b +c) = ab +ac
2(-a +5) = 2(-a) +2(5)
__
2.The multiplicative identity element is the value that can multiply any expression and leave it unchanged. It is 1. That is, multiplying anything by 1 leaves it unchanged.
This fact is generally used to cancel factors common to a numerator and denominator: (2x)/2 = x(2/2) = x(1) = x, for example. It is also used extensively in units conversion.
__
3.The associative property of addition lets you group the terms of a sum any way you like. It lets you move parentheses at will. (Beware subtraction.)
Here, the parentheses are moved from grouping the first two terms to instead grouping the last two terms.

Distributive Property of MultiplicationIdentity Property of MultiplicationAssociative Property of AdditionStep-by-step explanation:
Distributive Property of Multiplication
The distributive property of multiplication is to distribute or multiply one term by all terms.
2(-a + 5) Distrbute 2 to -a and 52(-a) + 2(5)-2a + 10Identity Property of Multiplication
Identity property is to multiply by 1. This doesn't change the value, so it keeps the value, identity, the same.
2/5 * 1 = 2/5Associative Property of Addition
The associative property is to group terms differently, preferably like terms. 2 and 5 are like terms, because they are integers.

Frederick asked a bank teller to cash a $390 check using $20 and $50 bills. If the teller gave
him 15 bills, how many of each did he receive?
12 of $20 and 3 of $50 totally didnt edit it... lolol..
Answer:
12 $20 Bills & 3 $50 Bills
Step-by-step explanation:
Because if the total is $390, Then if you get 10 $20 Bill that would equal $200 Bills and if you get 2 $50 Bills then you would get $100. Add the $200 Bills & the $100 Bills you get $300 Bills.
Then you get 1 $50 Bill and 2 $20 Dollar Bills you get $90 Bills.
Add $300 Bills with $90 Bills and you get $390.
If you add the number of bills handed it would be 15.
