An artist combines copper and other metals to make bronze. A bronze sculpture

natka813 [3]

Answer:

The dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.

Step-by-step explanation:

Since an artist combines copper and other metals to make bronze, and a bronze sculpture of a dolphin contains 43 g of copper for every 7 g of other metals, while a bronze sculpture of a bird contains 83 g of copper for every 17 g of other metals, to determine which sculpture is more coppery the following calculation must be performed:

Dolphin:

43 + 7 = 50

50 = 100

43 = X

43 x 100/50 = X

86 = X

Bird:

83 + 17 = 100

100 = 100

83 = X

83 x 100/100 = X

83 = X

Therefore, the dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.

60 days / 8 workers = 7.5

60 days - 12 days of work done = 48

48 x 7.5 = 360

360/ 12 workers = 30 days to finish rest of the house.

Find the exact values of the remaining five trigonometric functions of theta, suppose theta is an angle in the standard position

nexus9112 [7]

Answer:

$\sin(\theta)=60/61\text{ and } \csc(\theta)=61/60\\\cos(\theta)=11/61\text{ and } \sec(\theta)=61/11\\\tan(\theta)=60/11\text{ and } \cot(\theta)=11/60$

Step-by-step explanation:

So, we know that:

$\tan(\theta)=60/11\text{ and } 90\textdegree$

Since θ is in QI, this means that all of our trig ratios will be positive. Recall All Students Take Calculus. Since it's QI, we refer to A in All. The A tells us that all the ratios will be positive.

Now, let's figure out the remaining ratios knowing that all of them is positive. First, let's find the hypotenuse. Recall that tangent is the ratio of the opposite side to the adjacent side. So, we can use the Pythagorean Theorem to find the hypotenuse. So:

$a^2+b^2=c^2$
