Answer:
Step-by-step explanation:
Let be "x" the height inches (in the model) of a 84 foot building.
According to the information provided in the exercise, we know that the height of a two-story building is 21 feet and in the scale model its height is 3 inches.
Knowing this, we can set up the following proportion:
The final step is to solve for "x" in order to calculate its value. We get that this is:
Therefore, an 84 foot building will be 12 inches tall in the model.
Answer:
line a and b are parallel, there is no perpendicular lines
Step-by-step explanation:
Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.
When the slopes are the same, they are parallel.
When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex. and are perpendicular slopes.
Finding slope is using the formula:
Line a has slope =
Line b also has slope
Line c has slope 2
Since slope of line a and b are same, they are parallel.
Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.
Answer:
9 and 14
Step-by-step explanation:
We know that the perimeter is equal to:
P = 2l + 2w = 46
If we divide by 2, we are left with:
l + w = 23
I = 23 - w
Now the area is equal to:
A = l * w = 126
l * w = 126
Now replacing it, we are left with:
(23 - w) * (w) = 126
(-w ^ 2) + 23 * w = 126
Rearranging:
w ^ 2 + -23 * w + 126 = 0
We factor and we have:
(w - 9) * (w - 14) = 0
w - 9 = 0 => w = 9
w - 14 = 0 => 2 = 14
If w = 9, l = 23 - 9 = 14
If w = 14, l = 23-14 = 9
So the dimensions are 9 and 14.
Step-by-step explanation:
you'll use the previous date t fine the difference ex. if yesterday was 80 degrees and today's is 84 the difference would be 4 degrees. hope this helps a bit ( I'm pretty sure this is correct also remember if you need ask teacher for help!!)
Answer:
The answer is
<h2>7.61 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
<h3>
</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-3,-1) and (4, 2).
The distance is
We have the final answer as
<h3>7.61 units to the nearest hundredth</h3>
Hope this helps you
