Im not so sure about this. I need help making a proof that is 9 steps long. (See image)
Answers
Step-by-step explanation:
Not entirely sure, but I believe something like this:
∠1 + ∠2 = 180° since they are a linear pair;
Since ∠1 = ∠2, we can say:
∠1 + ∠1 = 180°
2(∠1) = 180°
∠1 = 90°
And since:
∠1 = ∠2
∠2 = 90°
So the angle between t and s is 90°;
An angle of 90° means t and s are perpendicular (⊥)

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.

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.

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.
