Round your answer to the nearest hundredth AC=

Mathematics
1 answer:
KatRina [158]2 years ago
7 0

Answer:

AC ≈ 2.96

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos65° = \frac{adjacent}{hypotenuse} = \frac{AC}{AB} = \frac{AC}{7}

Multiply both sides by 7

7 × cos65° = AC , thus

AC ≈ 2.96 ( to the nearest hundredth )

Fiona, Peter and Angad share some sweets in the ratio 4:5:1. Fiona gets 40 sweets. How many sweets are there altogether?
steposvetlana [31]

Answer:

100

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 + 1 = 10 parts

Fiona  gets 40 sweets which is 4 parts of the ratio

Divide Fiona's share by 4 to find the value of one part of the ratio

40 ÷ 4 = 10 ← 1 part of the ratio

The total number of sweets is 10 parts , thus

number of sweets in total = 10 × 10 = 100
