If steak costs $12.55 per pound, what will be the total cost of 0.6 pounds of steak?\
Answer:
Solve for X; whereas lb=pound, $=cost
1lb = $12.55
0.6lb = $X; therefore 6/10 lb = $X
Rewrite:
$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10
X=$7.53 for .6 lbs.

Step 1: Our output value is 700.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$700=100\%$700=100%.
Step 4: Similarly, $x=42\%$x=42%.
Step 5: This results in a pair of simple equations:
$700=100\%(1)$700=100%(1).
$x=42\%(2)$x=42%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{700}{x}=\frac{100\%}{42\%}$
700
x=
100%
42%
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{700}=\frac{42}{100}$
x
700=
42
100
Therefore, 42% of 700 is 294.

So, the answer is 63 in³.
Find the length of the third side. If necessary round the nearest tenth
Answer: 16.5
formula:
c^2 = a^2 + b^2
(a and b are the lines that form a right angle and c is the line that doesn’t)
a = 16
c = 23
Answer:
16.5
Step-by-step explanation:
a² + b² = c²
x² + 16² = 23²
x² + 256 = 529
x² = 273
x = √(273)
x = 16.52271164...
x ≈ 16.5

The sequence 18, 9, 9/2, 9/4, 9/8, ... represents the percentage of votes a particular political candidate has according to polls each day after a scandal. The sequence has a common
Answer:
r = 1/2Step-by-step explanation:
Given sequence:
18, 9, 9/2, 9/4, 9/8, ...We can see this is a GP and its common ratio is:
r = 9/8 ÷ 9/4 = 9/4 ÷ 9/2 = 9/2 ÷ 9 = 9 ÷ 18 = 1/2Common ratio
9/18=1/29/2/9=1/29/4/9/2=1/2Common ratio is 1/2

Question: Based on the data set above for the hours per day sixth graders spend using an electronic device, what is the mean number of hours sixth graders use an electronic device?
No links, useless words, or anything like that. I will report you.
Answer:
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
1+1+1+1+2+3=9
2+4+4+5+6+6+7+8+8=50

You borrow $450 to pay for a laptop. The interest rate is 2.8%. After 18 months, how much interest do you owe?
Answer:
226.8%
Step-by-step explanation:
The principal is $450
Interest is 2.8%
Time is 18 months
Therefore the interest can be calculated as follows
= 450×2.8×18/100
= 22,680/100
= 226.8 %
Hence the interest is 226.8%

Directions: Show all of your work for the following two problems on a seperate sheet of paper. Take a picture of your work and attach the picture to this assignment.
1. Solve the following system of equations, show all your work on a separate sheet of paper, and check your answer. Write the solution as a point (x,y) (4 points).
3x + 5y = -40
–x + 4y = -15?
2. Suppose you and your friends form a band and you want to record a demo. Studio A rents for $125 plus $50 an hour and Studio B rents for $200 and $30 an hour. Let t = the number of hours and c = cost.
Write an equation to represent the cost at each studio (2 points)
Solve the system (2 points)
Write the solution as a point (x, y) (2 points)
Answer:
x = -5 y = -5
Step-by-step explanation:
–x + 4y = -15
- 4y -4y
-1(-x = -4y - 15)
x = 4y + 15
Substitute x = 4y + 15 into 3x + 5y = -40
3(4y + 15) = -40
17y + 45 = -40
- 45 -45
17y = -85
/ 17 /17
y= -5
Substitute y = - 5 into x = 4y + 15:
x = 4(-5) + 15
x = -20 + 15
x = -5
Answer:
Part I
(-5,-5)
Part II
(3.75, 312.50)
Step-by-step explanation:
Part I
(1) 3x + 5y = -40
(2) -x + 4y = -15
solve for x in (2)
x = 15 + 4y
substitute into (1)
3(15+4y) + 5y = -40
45 +12y + 5y = -40
45 +17y = -40
17y = -85
y = -5
substitute y = -5 into (1)
3x + 5(-5) = -40
3x -25 = -40
3x = -15
x = -5
so (-5, -5)
Part II
Studio A
C = 125 + 50t
Studio B
C = 200 + 30t
125 + 50t = 200 + 30t
20t = 75
t = 3.75

how of find the area of a composite figure
Step-by-step explanation:
A composite figure is made up of simple geometric shapes. To find the area of a composite figure or other irregular-shaped figures, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure. Formula = a(a=lw+bh)
