Answer:

\boxed{BC = 11.9 \ cm}

Step-by-step explanation:

Sin A = \frac{opposite}{hypotenuse}

Where A = 58°, Opposite = BC and AC = 14 cm

Sin 58 = \frac{BC}{14}

BC = 0.848 * 14

BC = 11.9 cm

Answer:

<h2>BC = 11.9</h2>

Step-by-step explanation:

To solve for BC we use sine

sin ∅ = opposite / hypotenuse

From the question

AC is the hypotenuse

BC is the opposite

So we have

sin 58 = BC / AC

sin 58 = BC / 14

BC = 14 sin 58

BC = 11.87

BC = 11.9 to one decimal place

Hope this helps you

You have 29 thirds. This is a fraction greater than one.
hichkok12 [17]

You could make 9 wholes with that and there would be 2 thirds left over.

To solve it you would just have to divide 29 by 3 which would give you 9 and leave you with 2 thirds left.

Item 20 You pay $4.35 for 0.75 pound of American cheese. You buy 2.5 pounds of Swiss cheese for $7.98 per pound. a. How much les
Alexus [3.1K]

Answer:

a. $2.18

b. $15.60

Step-by-step explanation:

a. Price per pound of American cheese = $4.35 / 0.75 = $5.8

Price per pound of Swiss cheese = $7.98

Difference in price per pound = $7.98 - $5.8 = $2.18

b. Total amount spent on swiss cheese = $7.98 x 2.5 = $19.95

Amount spent more on Swiss cheese than on American cheese = $19,95 - $4.35 = $15.60
