Answer: D.45 inches, 75 inches
Step-by-step explanation:
Hi, to answer this question, first, we have to divide the board's length by the number of parts that conforms the 2 sections.
Since the ratio is 3/5, one section is made of 3 parts and the other section is made of 5 parts. 3+5 = 8 parts
120 / 8 = 15 inches
Each part measures 15 inches.
Now, we have to multiply each part's length by the number of parts that each section has. (3 and 5)
15x 3 = 45 inches
15 x 5 = 75 inches
The answer is f(x) = -2(0.7)^x that is the correct answer, I just did the question and got it right.
Answer:
ARE ≅ ΔARC
By rule - SSS Congruence Postulate
Step-by-step explanation:
We are given that in the two triangles ARE and ARC.
Sides AE ≅ AC and RE ≅ RC
Moreover, they have AR as their common side.
<em>So, we get that, in ΔARE and ΔARC, all the three corresponding sides are equal.</em>
Thus, by the SSS Congruence Postulate, ΔARE ≅ ΔARC.
Answer: 840 square inches
1. Split the figure into two rectangles.
2. Find x (there are other missing sides, but you do not need to know them).
x = 40 - 10
x = 30
3. Find the area of the two rectangles. Remember: A = lw.
Top rectangle: (10)(30) = 300
Bottom rectangle: (18)(30) = 540
4. Add the rectangles' areas together.
300 + 540 = 840
