Some algae contains up to 50% oil by weight. How much oil is in a 7.3-ounce sample of this type of algae?

This would help if you could solve anyone.

Answers

Answer 1

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

[tex]\frac{1}{2}[/tex] of 7.30 = [tex]3.65[/tex]

Hope this helps you!

cos4θ-cos2θ/sin4θ+sin2θ

Answers:
A. cotθtanθ
B. -cotθ
C. -tanθ
D. -1

Answers

Recall the double angle identities:

cos(2θ) = 1 - 2 sin²(θ)

sin(2θ) = 2 sin(θ) cos(θ)

With some rewriting, we can get

cos(4θ) - cos(2θ) = 2 cos²(2θ) - 1 - cos(2θ) = (2 cos(2θ) + 1) (cos(2θ) - 1)

and

sin(4θ) + sin(2θ) = 2 sin(2θ) cos(2θ) + sin(2θ) = sin(2θ) (2 cos(2θ) + 1)

The numerator and denominator both share a factor of 2 cos(2θ) + 1; canceling them leaves us with

(cos(2θ) - 1) / sin(2θ)

Replace cos(2θ) = 1 - 2 sin²(θ) and sin(2θ) = 2 sin(θ) cos(θ) :

((1 - 2 sin²(θ)) - 1) / (2 sin(θ) cos(θ))

-2 sin²(θ) / (2 sin(θ) cos(θ))

- sin(θ) / cos(θ)

- tan(θ)

so the answer is C.

Answer:

(cos4θ-cos2θ)/(sin4θ+sin2θ)

-[2sin((4θ+2θ)/2)sin(2θ-4θ)/2)]/[2sin((4θ+2θ)/2)cos (4θ-2θ)/2)]-sinθ/cosθ-tanθ

C. -tanθ is your answer.

Due to conservation efforts, the panda bear has been removed from the endangered species list. There are now 15,000 in the world, and the population is expected to grow by 10% yearly. Write an equation that models this scenario.

1. y = 15,000(1.10)x
2. y = 15,000(0.90)x
3. y = 15,000(0.10)x
4. y = 15,000(1.90)x

Answers

Answer:1

Step-by-step explanation:

you have to put the 1 infornt of the .10 if youre adding 10% more

Answer:

y = 15,000(1.10)x

Step-by-step explanation:

The equation y = 15,000(1.10)x represents the population of panda bears over time. In this equation, "y" represents the population, "15,000" represents the initial population of panda bears, and "1.10" represents the growth rate of 10% per year. The variable "x" represents the number of years.

By raising the growth rate of 1.10 to the power of "x" (the number of years), we account for the compounding effect of the growth rate over time. This equation allows us to calculate the population of panda bears after a specific number of years by multiplying the initial population (15,000) by the growth rate (1.10) raised to the power of the number of years.

For example, if we wanted to find the population after 5 years, we would substitute "x" with 5 in the equation:

y = 15,000(1.10)^5

This would give us the population of panda bears after 5 years, taking into account the annual growth rate of 10%.

A car tire has a radius of 10.4 inches. What distance will the tire travel after 20 rotations?

Answers

Answer:

Distance traveled after 20 rotations = 1306.24 inches

Step-by-step explanation:

r = 10.4 inches

Distance traveled in one rotation = Circumference of the car tire

Circumference of the car tire = 2πr

                                                 = 2 * 3.14 * 10.4

                                                = 65.312 inches

Distance traveled after 20 rotations = 65.312 * 20

                                                            = 1306.24 inches

Time traveler can take 5 books with him and he has 79 books to choose from how many different ways can the books be selected

Answers

We are given:

The time-traveller has 79 books, but he can only take 5 books

since we need to find the number of ways he can choose 5 books, we know that the order in which he takes the books does NOT matter

Hence, we will use combination

Finding the number of ways:

Since we will use combination, ₇₉C₅

We know that the formula for combination is  (n!) / (r!(n-r)!)

₇₉C₅  = 79! / 5!(74!)

₇₉C₅ = 22,537,515

Therefore, the time traveller can choose 5 books in 22,537,515 different ways

If carpet is 1.49 per square foot, how much will it cost for them to get new carpet for the master bedroom.

Answers

Answer:

The new carpet for the master room will cost $379.30

Step-by-step explanation:

The bedroom is a rectangle of dimensions:

[tex]4\sqrt {3}+6\sqrt {3}=10\sqrt {3}~ft[/tex]

[tex]6\sqrt {6}~ft[/tex]

Thus, the area of the master bedroom is:

[tex]A=10\sqrt {3}~ft*6\sqrt {6}~ft[/tex]

Multiply the coefficients and the arguments:

[tex]A=60\sqrt {18}~ft^2[/tex]

Calculating:

[tex]A=254.56~ft^2[/tex]

The carpet unit cost is $1.49 per square foot, thus the total cost of the new carpet is:

$1.49*254.56=$379.30

The new carpet for the master room will cost $379.30
