Mathematics

Answer:

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be $\frac{24}{26}$ and cos A (adjacent over hypotenuse) would be $\frac{10}{26}$ .

I hope this helps!

Answer:

the clock will represent 4.5 billion years as 2.67 hours

Step-by-step explanation:

Data provided in the question:

Total time of history of Earth = 4.5 billion years

Representation of total time of history of Earth on clock = 12 hours

Therefore,

4.5 billion years = 12 hours

⇒ 1 billion year =

⇒ 1 billion year = 2.67 hours

Hence,

Chef plans to serve 4.5 oz. steaks to 180 Guests. How many POUNDS only of raw steak should Chef order if Waste (trimming and coo

kotegsom [21]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of ounces steaks = 4.5 oz

Number of guests = 180

Percentage of waste = 25%

Number of ounces of fresh steak is given by

$4.5\times 180\\\\=810\ oz$

Let the number of ounces of raw steak be x.

According to question,

$\dfrac{100-25}{100}\times x=810\\\\\dfrac{75}{100}\times x=810\\\\0.75\times x=810\\\\x=\dfrac{810}{0.75}\\\\x=1080\ oz$

As we need in pounds, and we know that

1 pound = 16 ounces

So, Number of pounds of raw steak that Chef could order is given by

$\dfrac{1080}{16}=67.5\ lbs$

Hence, Option 'c' is correct.
