A billboard on level ground is supported by a brace as shown in the accompanying diagram the measure of angle is 15° greater than twice the measure of angle b determine the measure of angle a in the measure of angle b
Answer:
has a right angle to hold the billboard upright. Since a triangle is 180, and there' s a right angle, then when you add angle A and angle B together, they should add up to 90.
Step-by-step explanation:
A = 2B + 15
A + B = 2B+15 + B = 90
3B + 15 = 90
3B = 75, so B = 25 degrees
90 - B = A, so A = 65 degrees

A tuning fork moves with a velocity of 28.7 m/s with a frequency of 128 Hz. What is the wavelength of the
sound wave being produced?
0.22 m
b. 4.46 m
3673.60 m
d. 156.70 m
The value of the wavelength is 4.46m.The correct option is (b).
How to calculate the wavelength of a wave?The wavelength of a wave is defined as the distance between any two consecutive crests and troughs. It can be calculated by taking the ratio of frequency and velocity.
The expression for wavelength is given as follows,
λ = f / v
Where λ is the wavelength, f is the frequency and v is the velocity of the wave produced.
Substitute the corresponding values to obtain,
λ = 128/28.7
= 4.46
Hence, the wavelength of the wave produced by the tuning fork is given as 4.46 m.

In a scale model of the Eiffel Tower, 10 centimeters represent 65 meters. If the real Eiffel Tower is approximately 325 meters tall, how tall is the plastic model?
Answer:
The plastic model is 50 meters tall
Step-by-step explanation:
Here, we want to know how tall is the plastic model
In the plastic model 10 m represents 65 meters
then x meters plastic = 325 m real
10 * 325 = 65 * x
3250 = 65x
x = 3250/65
x = 50 meters

I NEEED HELP WITH THIS MATH
Answer:
3. they combined like factors incorrectly X=21.5
4. Supplementary means it's equal to 180, not 90. they did it as if the angle was acute. The answer should be 133 degree
5. The two angles are not equal. however, the two angles added together equal to 180. 115+ 5x -10 = 180 X=15
Step-by-step explanation:
3. 8x + 8 = 180
8x + 8 - 8 = 180 - 8
8x = 172
8x/8=172/8
x=21.5
4. 180-47= 133
5. 115 - 10 + 5x = 180
105 + 5x = 180
105-105+5x=180-105
5x=75
5x/5=75/5
x=15

y=fx-1 is perpendicular to
y=-3x+2. Casey disagreed and
said y=-x-1 is perpendicular
to y=-3x + 2. Which person is
correct and why?
A Casey is correct. In order to find
the perpendicular line to another
line, one must take the
reciprocal of the slope.
B Tara is correct. In order to find

Help!!!! Teah was selling candy bars for a fundraiser. She spent $25 on a box of candy bars and sold each candy bar for $2.50. Her profit was $75. Teah wrote the equation 2.5c−25=75 for this situation, and she found c=40.
Which statement is true about the solution c=40?
1. The solution c=40 is the amount in dollars that Teah spent on a box.
2. The solution c=40 is the number of candy bars Teah sold.
3. The solution c=40 is the selling cost of each candy bar, in dollars. (Wrong)
4. The solution c=40 is the profit in dollars Teah made from each candy bar.
5. The solution c=40 is the selling cost of a box of candy bars, in dollars.
Answer:
The answer is 2
Step-by-step explanation: It is 2 because you can just use the process of elimination 1 is wrong because you know how much she spent on a bod $25 and 3 is wrong because she is selling the candy bars for $2.50 we know that the story tells us that and 4 is wrong because the story tells us her profit was $75 not $40 and 5 is wrong because we already know the selling cost of a box of candy bars in dollars $25 so when you use the process of elimination trick you only have 1 answer left and that's 2.
2 is the answer
