Find the value of the angle θ rounded to 1 DP.

Mathematics
1 answer:
kogti [31]2 years ago
5 0

Answer:

Step-by-step explanation:

Sin 21 = \frac{opposite side}{hypotenuse}

Sin 21 = \frac{BC}{15}

0.3583 = \frac{BC}{15}

0.3583*15 = BC

BC = 5.3745 = 5.37 m

Tan ∅ = \frac{opposite side}{adjacent side}

Tan ∅ = \frac{4}{5.37}= 0.7448

∅ = tan⁻¹ (0.7448) = 36.67 = 36.7

rosijanka [135]

Answer:

<em>47. 1 inches ; where inches ⇒ units</em>

Step-by-step explanation:

Consider the Circumference as such;

Diameter - 15 inches,\\Circumference - 2\pi r, r - radius,\\\\2\pi r = \pi d, d - diameter ( considering, 2 * r = diameter )\\\\Circumference = \pi * d = \pi * diameter = \pi * 15 = ( About ) 47.1 inches\\Solution; Circumference = ( About ) 47.1 inches

Your French fries have a food cost of $0.50, and you want to have a margin of 75% on the fries. What will the final selling pric
AleksandrR [38]

Answer:

\frac{0.5}{100} = \frac{x}{175}

0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:

x= 175 *\frac{0.5}{100} =0.875

So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin

Step-by-step explanation:

For this case we know that the french fries cost $0.50 and we want to have a margin of 75% on the fries. So we can use the following proportional rule:

\frac{0.5}{100} = \frac{x}{175}

0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:

x= 175 *\frac{0.5}{100} =0.875

So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin
