Solve for n.
m=n/r+t
Answer:
n = m r - r t
Step-by-step explanation:
Solve for n:
m = n/r + t
Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.
m = n/r + t is equivalent to n/r + t = m:
n/r + t = m
Hint: | Isolate terms with n to the left hand side.
Subtract t from both sides:
n/r = -t + m
Hint: | Solve for n.
Multiply both sides by r:
Answer: n = m r - r t

A 96 in. board will be cut into pieces to add a decorative trim to a rectangular table. The length of the table is twice the width. All of the board will be used to add the trim, and the board will be cut into only four pieces to match the four sides of the table. Find the location of the cut marks on the board...
Answer:
16, 16, 32, 32
Step-by-step explanation: If you take 92 and divide it by 4 you get 24 but you need one side to be longer than the other, subtract 6 and you get 16, and 16x2 is 32, if you add 16+16+32+32 you get 96.

Two cards are drawn from the pack of 52 cards. Find the probability that both are diamonds or both are kings.
=========================================================
Work Shown:
There are 13 diamond cards. The probability of getting a diamond card is 13/52 = 1/4.
Assuming the first card is not replaced, the probability of getting another diamond card is 12/51. Note how I subtracted 1 from the numerator and denominator of 13/52 to get 12/51.
Multiply the two fractions to get
(1/4)*(12/51) = 12/204 = 1/17
The probability of getting two diamonds in a row is 1/17
We'll use this later, so let A = 1/17.
---------------------
There are 4 kings. The probability of pulling out a king is 4/52 = 1/13
The probability of pulling out another king is 3/51 = 1/17
The probability of pulling out two kings in a row is (1/13)*(1/17) = 1/221
Let B = 1/221
---------------------
Add the values of A and B
A+B = 1/17 + 1/221
A+B = 13/221 + 1/221
A+B = (13+1)/221
A+B = 14/221
A+B = 0.0633 which is approximate
That converts to 6.33% when you move the decimal point over 2 spots to the right.
We have that the probability that both are diamonds or both are kings.
P(D+K)=32\%
From the question we are told
Two cards are drawn from the pack of 52 cards. Find the probability that both are diamonds or both are kings.
Generally the equation for the both are diamonds or both are kings is mathematically given as
[tex]P(D+K)=\frac{d}{52}+ \frac{k}{52}[/tex]
Therefore
[tex]P(D+K)=\frac{13}{52}+ \frac{4}{52}\\\\P(D+K)=0.32[/tex]
P(D+K)=32\%

Talia is packing a moving box. She has a square-framed poster with an area of 4 square feet. The cube-shaped box has a volume of 13 cubic feet. Will the poster lie flat in the box? Explain?
The volume of a cube = e^3
e = a single edge of the cube.
Area of a square = a^2
a = a single side of the square.
The volume of our cube = 13 ft^3
e = [tex]\sqrt[3]{13}[/tex] = 2.35 ft
The area of our square = 4 ft^2
a = [tex]\sqrt{4}[/tex] = 2 ft
The edge of our cube is greater than the length of our square's side.
The poster will lie flat in the box.

Answer:

Step-by-step explanation:
The theoretical probability of getting a number is 1/6 since there is 6 sides
We rolled the dice 60 times
The experimental = x/60 where x is the number of times the number comes up
We want the theoretical to equal the experimental
1/6 = x/60
1/6 * 10/10 = 10/60
x = 10
This occurs for the number 4
solve for f
-f +2 + 4f = 8 - 3f
Answer:
f=1
Step-by-step explanation:
Let start off with doing -f plus 4f which gives you 3f. The equation would now be 2+3f=8-3f. Add 3f so you can cancel out the -3f and add the 3f to the other 3f. Now your equation is 2+6f=8. Cancel out do by doing -2. (Don't forget to to it to the 8 also.) Now your equation is 6f=6. Divide 6 from both sides to get 1. (You divide because you want to get f alone.

AB = 6x + 2 and
BC = 5x + 3
Find AC.
That is a difficult one
Assuming A, B and C are all on the same straight line, this means,
AB+BC = AC
through the segment addition postulate.
So,
AC = AB+BC
AC = (6x+2)+(5x+3)
AC = 6x+2+5x+3
AC = (6x+5x)+(2+3)
AC = 11x+5What is the answer to 0.02 is 1/10 of?
Answer:

0.002 x 10 as it is 1/10 of the size
The answer is 0.2.
Here,
We have to find the number as 'the answer to 0.02 is 1/10 of the number.'
What is Mathematical expression?
The combination of numbers and variables by using operations addition, subtraction, multiplication and division is called Mathematical expression.
Now,
Let the number is x.
Then, By given condition the expression is written as;
0.02 = (1/10) * x
(1/10) * x = 0.02
x = 0.02 * 10
x = 0.2

# Expand (2x - 3)2. If a, b, and c represent
the coefficients of the resulting polynomial in
descending powers of x, what is a+b+c?
Answer:
a + b + c = 1
Step-by-step explanation:
To expand the bracket, [tex](2x - 3)^{2}[/tex] we will simply be multiplying the bracket by itself.
This will be the same as having [tex](2x - 3) \times (2x - 3)[/tex]
The first step in doing this is to multiply each of the values in the second bracket by the values in the first one.
[tex]2x \times 2x =4x^2[/tex]
[tex]2x\times -3 = -6x[/tex]
[tex]-3 \times 2x = -6x[/tex]
[tex]-3 \times -3 =9[/tex]
Once this is done, the next step is to group the like terms and evaluate the result.
[tex]4x^2 -6x-6x +9[/tex]
[tex]4x^2 -12x +9[/tex]
This is algebraic expression is the result of the expansion of [tex](2x - 3)^{2}[/tex] .
Based on the descending powers of x
a = 4
b = -12
c = 9
These are the coefficients of [tex]x^2[/tex] and [tex]x[/tex] and also the last figure.
a + b + c = 4 -12 +9 = 1
find the coordinates of A if M (-1,2) is the midpoint of AB and if B has coordinates of (3,-5)
Answer:
07
Step-by-step explanation:
The coordinate of A is (-5, 9) if M (-1,2) is the midpoint of AB and if B has coordinates of (3,-5).
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]
It is given that:
The coordinate of the midpoint of AB is M (-1,2)
The coordinate of B is (3, -5)
Let (x, y) be the coordinate of A.
From the mid-point theorem:
(x + 3)/2 = -1
x + 3 = -2
x = -2 - 3
x = -5
(y - 5)/2 = 2
y - 5 = 4
y = 4 + 5
y = 9
The coordinate of A is (-5, 9) and the coordinate of B is (3, -5)
The mid-point of the line segment AB
The coordinate of M is (-1, 2).
Thus, the coordinate of A is (-5, 9) if M (-1,2) is the midpoint of AB and if B has coordinates of (3,-5).
