I do not understand this problem

Answers

Answer:

$89.70 or $192.30

Step-by-step explanation:

All you have to do is multiply 26 by 3.45 and you get your answer. Which if you use a calculator it would say 89.7, to find the answer you just add a zero to the end.

If you're doing the second answer you multiply 30 by 3.45, then you take 26 and multiply by 3.45, after that you add them together and you get your answer.

Over the interval [0, 2pi), what are the solutions to cos(2x) = cos(x)? Check all that apply.

Answers

Answer:0, 2pi/3, 4pi/3

Step-by-step explanation:

did on edge

The solutions that satisfy Sin(2x) = Sin(x) are; 0,π/3, π, 5π/3. The options that satisfy the condition are 1,2,4 and 6.

What is meant by a trigonometric ratio?

In mathematics, trigonometric functions (also known as circular functions, angle functions, or goniometric functions) are real functions that relate an angle of a right-angled triangle to ratios of two side lengths.

Given the interval is [0, 2pi)

Sin(2x) = Sin(x)

By checking all the options;

1) Sin 2(0)=sin0

Sin0=Sin0

Therefore, option 1 is correct

2) Sin 2x= Sin x

2Sin x Cos x= Sin x

2 Cos x=1

Cos x=1/2

Cos x= Cos π/3

x=π/3

Therefore, option 2 is correct.

3) Sin2(2π/3) = Sin(2π/3)

Sin(4π/3)=Sin(2π/3)

Sin 240°=Sin 20°

-√3/2≠√3/2

Therefore, option 3 is wrong

4) Sin(2π)=Sinπ

2Sinπ Cosπ=Sinπ

2×0×(-1)=0

Therefore, option 4 is correct

5) Sin 2(4π/3)= Sin(4π/3)

Sin 480°=Sin 240°

2 Sin 240° x Cos 240°= Sin 240°

2(-√3/2)(-1/2)= -√3/2

√3/2≠-√3/2

Therefore, option 5 is wrong

6) Sin 2(5π/3)= Sin(5π/3)

2 Sin(5π/3)Cos (5π/3)=Sin(5π/3)

Cos(5π/3)=1/2

Therefore, option 6 is correct.

The number of gifts Nikki can varies directly with the amount of time she spends wrapping them . She can wrap 14 gifts in 2 hours. How many gifts can she wrap in 6 hours

Answers

Answer:

42 gifts

Step-by-step explanation:

Multiply 14 by 3 to get 42 (6 hours worth of wrapping gifts)

2*3=6

14*3=42

If Nikki can wrap 14 gifts in 2 hours. Then she can wrap 42 gifts in 6 hours

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

The number of gifts Nikki can varies directly with the amount of time she spends wrapping them.

The number of gifts nikki can wrap in 2 hrs=14.

Now we need to find how many gifts can she wrap in 6 hours.

Let x be the number of gifts she wrap in 6 hours.

2/14=6/x

1/7=6/x

Apply cross multiplication

x=7×6

x=42

Hence, Nikki can wrap 42 gifts in 6 hours.

Answer:

50 minutes

Step-by-step explanation:

"Working together" problems like this usually give you the time per task. However, the rates of getting work done add when expressed as tasks per time.

Let b represent the number of minutes Bob takes to mow the lawn alone. Then the sum of lawns mowed per minute is ...

Jamie's rate + Bob's rate = "working together" rate

1/75 + 1/b = 1/30

1/b = 1/30 -1/75

1/b = 5/150 -2/150 = 3/150

1/b = 1/50

b = 50

It takes Bob 50 minutes to mow the lawn alone.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Slope = Rise² + Run²

Slope² = 10² + 15²

The slope is 5√13.

What is the Pythagorean theorem?

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

The slope, rise, and run are in the form of a right triangle.

We will apply the Pythagorean theorem to get the slope.

Sope can be considered as the hypotenuse.

Now,

Slope = Rise² + Run²

Slope² = 10² + 15²

Slope² = 100 + 225

Slope² = 325

Slope = √325

Slope = √(25 x 13)

Slope = 5√13

Thus,

The slope is 5√13.
