Please see the attached picture to see the similar triangle.
The new triangle has triple the side lengths of the first one. This means all side lengths will be triple.
You will use this ratio to find the new side lengths and then use them to find the perimeter and area.
3:4:5 = 9 cm: 12 cm:15 cm on triangleABC
1. The
perimeter is 9cm + 12 cm + 15 cm or
36 cm.
2. The
area is 1/2 x 12 x 9 or
54 square cm.
3. The length of the
hypotenuse is
15 cm.
Answer:
1998
Step-by-step explanation:
6 chalk boards x 3 grades = 18 chalk boards
18 chalk boards x $98 per chalk board = $1,764
Answer: 5/9 x 2/8. The probability that the first marble is green and the second is red is 13.8%. In fraction form, the answer is 5/9 x 2/8 because the two outcomes must be multiplied. I really hope that helps!
Answer:
The expressions which equivalent to are:
⇒ B
⇒ C
Step-by-step explanation:
Let us revise some rules of exponent
Now let us find the equivalent expressions of
A.
∵ 4 = 2 × 2
∴ 4 =
∴ =
- By using the second rule above multiply 2 and (n + 2)
∵ 2(n + 2) = 2n + 4
∴ =
B.
∵ 4 = 2 × 2
∴ 4 = 2²
∴ = 2² ×
- By using the first rule rule add the exponents of 2
∵ 2 + n + 1 = n + 3
∴ =
C.
∵ 8 = 2 × 2 × 2
∴ 8 = 2³
∴ = 2³ ×
- By using the first rule rule add the exponents of 2
∵ 3 + n = n + 3
∴ =
D.
∵ 16 = 2 × 2 × 2 × 2
∴ 16 =
∴ = ×
- By using the first rule rule add the exponents of 2
∵ 4 + n = n + 4
∴ =
E.
is in its simplest form
