Answer:
$2.06
Step-by-step explanation:
$2.99 x 6 = $17.94
$20.00 - $17.94 = $2.06
Hope this helps
Answer: $0.26
Step-by-step explanation:
Cost of 6 pens
= 2.99 x 6
= 17.94
Add sales tax at 10%,
= 17.94 x 1.1
= 19.74
Change due to me
= 20 - 19.74
= 0.26
A) The triangles are not similar
B) ΔABC ∼ ΔHFG
C) Impossible to determine.
D) ΔABC ∼ ΔFHG
Answer:
Step-by-step explanation:
The two triangles are similar.
The corresponding sides are proportional.
AB ∼ FH
AC ∼ FG
BC ∼ GH
A. True
B. False
answer TRUE because they would make a triangle
How many times is the volume of the large sphere than the
small sphere?
2
VX
O 4
O 6
O 8
Answer:
4 times as great
Step-by-step explanation:
Compute the two different volumes and then compare them.
Smaller sphere: V = (4/3) · π ·r²
Larger sphere: V = (4/3) · π · (2r)² = (4/3) · π · 4 · r²
Comparing these, one sees immediately that the volume of the larger sphere is 4 times as great as that of the smaller sphere.

Answer:
210.33 cm^2
Step-by-step explanation:
We know that 6 equilateral triangles makes one hexagon.
Also, an equilateral triangle has all its sides equal.
If the tile of each side of the triangular tile measure 9 cm, then the height of the triangular tiles can be gotten using Pythagoras's Theorem.
The triangle formed by each tile can be split along its height, into two right angle triangles with base (adjacent) 4.5 cm and slant side (hypotenuse) of 9 cm. The height (opposite) is calculated as,
From Pythagoras's theorem,
substituting, we have
81 = 20.25 +
= 81 - 20.25 = 60.75
opp = = 7.79 cm this is the height of the right angle triangle, and also the height of the equilateral triangular tiles.
The area of a triangle =
where b is the base = 9 cm
h is the height = 7.79 cm
substituting, we have
area = x 9 x 7.79 = 35.055 cm^2
Area of the hexagon that will be formed = 6 x area of the triangular tiles
==> 6 x 35.055 cm^2 = 210.33 cm^2
