Answer: total $1332
Step-by-step explanation:
1200x11%=132
1200+132=1332
Answer:
1. 14 cm
2. 20.4 cm
3. 24 - w
Step-by-step explanation:
Let's start with the last question, as it'll make answering the previous two a lot easier. In the 3rd question, we are asked to create a formula to find the length of a given rectangle, using its given perimeter of 48 centimeters and width of 
centimeters.
Therefore, let the length of the rectangle be 
, we can construct the following equation:
Now we have a formula that defines our length, if given the width of the rectangle. The only thing from here on out is to substitute the given widths to the formula we just found.
1. 
, therefore, 
.
2. 
, therefore, 
.
Answer:
y-intercept: (0, -0.7)
x-intercept: (-1.2, 0)
Step-by-step explanation:
- To find the x-intercept (x, 0) of a line substitute y by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the x-axis
- To find the y-intercept (0, y) of a line substitute x by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the y-axis
In the given figure
∵ The line intersects the y-axis at the point (0, -0.7)
∴ The point of intersection between the line and the y-axis is (0, -0.7)
→ By using the 2nd note above
∴ The y-intercept is (0, -0.7)
∵ The line intersects the x-axis at the point (-1.2, 0)
∴ The point of intersection between the line and the x-axis is (-1.2, 0)
→ By using the 1st note above
∴ The x-intercept is (-1.2, 0)
Answer:
yes
Step-by-step explanation:
The value 8 is the solution to the equation because plugging 8 into the equation in place of the unknown variable x like 16(8) will equal 128.
Answer:
x = 
Step-by-step explanation:
Applying altitude- on - hypotenuse theorem.
(leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 3 × (3 + 7) = 3 × 10 = 30 ( take square root of both sides )
x =
