8Express Sin A, Cos A, And Tan A As Ratios.12613

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{6\sqrt{3} }{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]

cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{6\sqrt{3} }{6}[/tex] = [tex]\sqrt{3}[/tex]

Joy has a ribbon that measures 16 yards. She cuts 9 pieces of ribbon to decorate gifts. Each piece of ribbon that Joy cuts measures 4 feet.

What is the length, in yards, of the remaining ribbon?

Answers

Answer:

4 yds

Step-by-step explanation:

So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)

and she cuts 9 pcs of ribbon each 4 feet

so it's 9 x 4 = 36

48 - 36 = 12

And 12 feet equals 4 yards

So, Joy has 4 yards of remaining ribbon

Answer:

9.3 yards

A charity distributed 80 000 emergency packages during 2018. This number is
expected to increase by 15% each year.
Calculate how many emergency packages the charity expects to distribute in 2021.

Answers

Answer:

121670

Step-by-step explanation:

The number of packages can be defined with the function:

P(t) = P(t-1)*1.15 where t = the years and 1.15 represents the 15% increase.

Packages during 2018: P(2018) = 80000

Packages during 2019: P(2019) = P(2018)*1.15 = 92000

Packages during 2020: P(2020) = P(2019)*1.15 = 105800

Packages during 2021: P(2021) = P(2020)*1.15 = 121670

please help thank you

Answer:-

Work out the medium
Work out the mean

Answers

Answer:

The medium - 6,6

The mean - 5.1 or 5

Step-by-step explanation:

The medium is the middle number(s)

The mean is when you average the numbers (adding them all up then dividing by how many numbers there are).

Answer: before u do all of this put the number in smallest to biggest the mean is u add all the number then when u get the answer u divide the number by how many numbers are there so 2 + 3+3+4+5+6+6+6+7+9= 51 now 15 divided by 10 =5.1 that is the mean

Now the medium is u put the number in smallest to biggest again 2334566679 now u have to find the numbers that are the same so u see how there is two 3's and three 6's in the numbers right so u have to look very carefully u could put 3 has the answer put that is not the answer because there is only two 3's and there is three 6's so which is bigger two 3's or three 6's three 6's is bigger so that is the answer.
