Answer:
-1.9
Step-by-step explanation:
The opposite of the opposite is the original number, -1.9.
It is located at -1.9 on the number line.
False I think it doesn't add up to 18
Answer:
90 sq inches
Step-by-step explanation:
The lateral area is the side area of the pyramid. In this case, there are 3 sides because the base is a triangle. Since the base is an equilateral triangle, all sides are of equal dimensions. So, the sides of the pyramid are also all of the same size, area.
We then just have to figure out the area of one of the side triangles, then multiply it by 3 to get the total lateral area of that pyramid.
We know how to calculate the area of a triangle: A = (b * h)/2
In this case, b = 5 in, h = 12 in. So,
TA = (5 * 12)/2 = 60 / 2 = 30
Each side triangle has an area of 30 sq inches.
LA = 3 * TA (since there are 3 sides)
LA = 3 * 30 = 90 sq inches
Answer:
D. y-4= -3/2(x+5)
Step-by-step explanation:
Firstly, taking two valid ordered pairs from the graph:
(-2,4) and (2,-2)
Using Delta y over Delta x, we are able to obtain m as -3/2
Next,
The following is the point-slope formula:
y-y₁=m(x-x₁)
Based on the graph, (4,-5) can be spotted as a definite ordered pair
Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.
Answer:
the new lengths are 10.8 ft and 8.8 ft
Step-by-step explanation:
l=length added
w=width added
35ft originally
95ft= (5+l)times(7+w)
w=1.8ft
l=5.8ft
95ft=(5+5.8)times(7+1.8)
