<span>a=7b+8c+9d-10
a = 8c + 16d - 10
solve for c then
8c = a - 16d + 10
c = (</span>a - 16d + 10) / 8
or
c = a/8 - 2d + 5/4
Answer:
Answers are below in bold
Step-by-step explanation:
1) A = 1/2bh Use this equation to find the area of each triangular base
A = 1/2(8)(6) Multiply
A = 1/2(48) Multiply
A = 12cm² Area of each triangular base
2) A = L x W Use this equation to find the area of the bottom rectangular face
A = 20 x 8 Multiply
A = 160 cm² Area of the bottom rectangular face
3) A = L x W Use this equation to find the area of the back rectangular face
A = 20 x 6 Multiply
A = 120 cm² Area of the back rectangular face
4) A = L x W Use this equation to find the area of the sloped rectangular face
A = 20 x 10 Multiply
A = 200 cm² Area of the sloped rectangular face
5) To find the total surface area of the triangular prism, add together all of the numbers.
A = 12 + 12 + 160 + 120 + 200 Add
A = 504 cm² Total area of the triangular prism
Answer:
about 10 without a remainder of 4
Step-by-step explanation:
So, add up the number and divide by how many number you have (definition of mean). 8 + 25 + 9 + 10 + 11 + 1 all divide by 6 (since there are 6 numbers)
8 + 25 + 9 + 10 + 11 + 1 is 64.
64/6 is about 10 without a remainder of 4
Answer:
Step-by-step explanation:
It is given that triangle AOC intersects a circle with center O, side AO is 10 inches and the diameter of the circle is 12 inches, thus
OC is the radius of the circle and is equal to 
.
Now, From ΔAOC, using the Pythagoras theorem, we get
⇒

Answer:
∠STR =
∠XYT
Step-by-step explanation:
The triangles are give congruent.△RST ≅ △TXY.
In congruent triangles corresponding angles are equal.The order of the letters in the congruent statement matters.
In the given statement the angles matching to ∠STR is ∠XYT.
Hence ,the equal angles in the congruent triangles are ∠STR = ∠XYT.
