With a proper fraction, the whole number would get smaller
A) Net A would be the correct net for the prism.
B) AB = 3in
BC = 5in
CD = 8.6in
C) area of one triangle : 4*3/2 = 6
But there's 2 triangles so 6*2 = 12cm2
Area of the middle square : 8.6*4 = 34.4cm2
Area of bottom square : 8.6*5 = 43cm2
Area of top rectangle : 8.6*3 = 25.8cm2
Finally add all of these areas together and you will get the surface area : 115.2cm
Answer:
80 percent
Step-by-step explanation:
What percent of 110 is 88
p * 110 = 88
divide by 110 on each side
p = 88/110
p = .8
multiply by 100 to get percent
80 percent
The height of the mountain estimated by two students is 2,467.98 meters.
<h3>
Height of the mountain </h3>
The height of the mountain is calculated as follows;
tanα = h/( a + b + x)
where;
- x is the distance between end of b and h
tan37 = h/(1850 + 740 + x)
tan37 = h/(2590 + x)
h = tan37(2590 + x)
h =1,951.82 + 0.7536x ---- (1)
tanβ = h/(b + x)
tan60 = h/(740 + x)
h = tan60(740 + x)
h = 1,281.68 + 1.732x ---- (2)
Solve (1) and (2) together
1,951.82 + 0.7536x = 1,281.68 + 1.732x
1,951.82 - 1,281.68 = 1.732x - 0.7536x
670.14 = 0.9784x
x = 684.93 m
h = 1,281.68 + 1.732x
h = 1,281.68 + 1.732(684.93)
h = 2,467.98 m
Thus, the height of the mountain estimated by two students is 2,467.98 meters.

Answer:
Vertex is (-1/3, -13/3)
Axis of symmetry is x = -1/3
Step-by-step explanation:
For the vertex, you need to change it into vertex form which is y = a(x - h)^2 + k
Vertex form for this equation is:
Y = -6(x + 1/3)^3 - 13/3
To find the vertex, the formula is (h,k)
So, ( -1/3, -13/3)
