Step-by-step explanation:
Area of a Rectangle
A rectangle of width W and height H has an area of:
A = W.H
We have one rectangle inside another. The first rectangle corresponds to the frame and its contents. The second rectangle corresponds to the photograph.
The area of the frame without its contents is the difference between both areas:
Where Ae is the external area of the frame, and Ai is the internal frame of the photograph.
The frame has W=4 inches and L=6.5 inches, thus:
The photograph has W=3 inches and L=5 inches, thus:
The area of the frame is:
Area = l × w
= 6.5 × 4
= 26 feet2
The following steps of solving for the roots of 2x² - 4x -3 = 0 were retrieved from another source Step 1 2x² - 4x = 3 Step 2 2(x² - 2x) = 3 Step 3 2(x² - 2x + 1) = 3 + 1 Step 4 2(x - 1)² = 4 From this, we can see that on Step 3, Tran made a mistake of adding 1 to 3. As we can see, 2(x² - 2x + 1) = 2x² - 4x + 2. That means, instead of adding 1, it should have been 2. Therefore, the step that Tran first made an error is Step 3.
The midpoint formula states that the midpoint is equal to (x1 + x2/2, y1 + y2/2). However, in this instance, we only have to deal with the x-values because that is where our unknown variable x is. Using our formula for the x-values, we can set up the following equation:
(x + 9)/2 = 7
To solve this equation, we must first multiply both sides by 2 to get rid of the denominator on the left side of the equation.
x + 9 = 14
Next, we should subtract 9 from both sides of the equation to get the variable x alone on the left side.
x = 5
Therefore, your answer is x=5.
Hope this helps!
Step-by-step explanation:
Given data:
Cars Vans Others
60 21 3
The data represents the number of cars on a single day.
Find the relative frequency;
It is the number of times an event occurs.
Here the time frame is within a day;
Relative frequency =
Relative frequency = 60 + 21 + 3 = 84vehicles per day
ii.
Number of vans in a week;
Number vans in a week = 21van per day x 7 days = 147vans
