Answer:
- For 5 bows, 10/3 yards of ribbon is required.
Step-by-step explanation:
<u>We know that:</u>
<u>Work:</u>
- 2/3 yards = 1 bow
- => 2/3 x 5 yards = 5 bows
- => <u>10/3 yards = 5 bows</u>
Hence, for 5 bows, 10/3 yards of ribbon is required.
Step-by-step explanation:

Represent cost with C, length of bridge with L and depth of water with D.
- & represents directly varies as
; C & L
; C & D²
therefore C & LD²
; C = kLD².......k is a constant
700,000 = k × 200 × 8²
700,000 = k × 200 × 64
700,000 = 12800k
700,000 / 12800 = k
54.6875 = k
The relationship therefore is C = 54.6875 × LD²
What are we then to do??
PLEASE, forgive me but I answered this and hopefully what I see is correct. I’m really sorry if this weren’t the real measurements!
Answer:
192 square inches
Step-by-step explanation:
Surface area questions often include the net for easy answering. All you do is just find the area of each face and add them all up:
As you can see, all triangles in this net of a pyramid are the same, so once we find the area of one triangle, we’ll just multiply by 4:
FIND AREA OF ONE TRIANGLE (1/2 x b x h)
1/2 x 8 x 12 = 48 square inches
MULTIPLY BY 4 for SURFACE AREA:
48 x 4 = 192
so the SA is 192 square inches!

Answer:
10
Step-by-step explanation:
2 + 5 = 7
3 + 5 = 8
4 + 5 = 9
5 + 5 = 10
i) Plan A: 21/0,12 = 175 <min of calls>
Plan B: 15/0,14 ≈ 107 <min of calls>
=> 2 plans cost the same 107 min of calls
ii) The cost when 2 plans cost the same:
- Plan A: 107 × 0,12 = 12,84$ ≈ 13$
- Plan B: 107 × 0.14 ≈ 15$
Answer: i) 107 ii) A: 13$ B: 15$
