A firework exploded 1,360 meters away and the sound of the firework took 4 seconds to reach you. At what speed did the sound travel?
Answer:
Speed of sound, v = 340 m/s
Step-by-step explanation:
It is given that,
A exploded 1360 meters away, d = 1360 meters
time taken, t = 4 seconds
We need to find the speed of the travelled sound. Speed of sound is equal to the distance covered divided by total time taken i.e.
[tex]v=\dfrac{d}{t}[/tex]
[tex]v=\dfrac{1360\ m}{4\ s}[/tex]
v = 340 m/s
So, the speed with which sound is travelled is 340 m/s. Hence, this is the required solution.

The graph of the equation y = 3x + 4 is shown. Determine the value of y for the point
(-1, y).
To find the value of y for the point (-1, y) in the equation y = 3x + 4, plug in -1 for x and solve: y = -3 + 4, which simplifies to y = 1. Thus, the value of y is 1.
The student needs to determine the value of y when x is -1 for the equation y = 3x + 4. To find y, we substitute -1 in place of x and solve the equation:
y = 3(-1) + 4
y = -3 + 4
y = 1
Therefore, the value of y for the point (-1, y) is 1.
The area of a rectangle is 45 square inches. The rectangle is 9 inches long. How wide is the rectangle?
A. 5 inches
B. 36 inches
C. 27 inches
D. 3 inches
Final answer:
To find the width of a rectangle with an area of 45 square inches and a length of 9 inches, divide the area by the length, resulting in a width of 5 inches (Option A).
Explanation:
The area of a rectangle can be calculated by multiplying its length by its width. In this case, we know the area is 45 square inches and the length is 9 inches. To find the width, we divide the area by the length.
Width = Area ÷ Length = 45 sq in ÷ 9 in = 5 in
Therefore, the width of the rectangle is 5 inches, which corresponds to option A.

A video game arcade offers a yearly membership with reduced rates for game play. A single membership costs $60 per year. Game tokens can be purchased by members at the reduced rate of $1.00 per 10 tokens. Which statements represent the function of the yearly cost in dollars, y, based on x, the number of game tokens purchased for a member of the arcade? Check all that apply. The slope of the function is $1.00. The y-intercept of the function is $60. The function can be represented by the equation y = 1/10x + 60. The domain is all real numbers. The range is {y| y ≥ 60}.

What is a Decimal and fractional Numbers?
Decimal numbers include those numbers which have a whole number and the fractional part separated by a decimal point. Example -
2.33, 4.55, 5.6
A common fraction is a numeral which represents a rational number. That same number can also be represented as a decimal, a percent, or with a negative exponent. Example -
2/5, 5/6, 7/9
We have a fraction 2/3.
The decimal number equal to 2/3 is 0.67.
Hence, decimal number equal to 2/3 is 0.67.

Triangle A B C with angle A measuring thirty degrees, angle B measuring seventy degrees and angle C marked x
Answer: In a triangle, the sum of the 3 angles is always equal to 180°
Then if the angle A is equal to 30°, the angle B is equal to 70°, what is the angle C?
if x is the angle C, and using the first statement, we got:
30° + 70° + x = 180°
100° + x = 180°
x = 180° - 100° = 80°
So the angle of C is equal to 80°.

Write an equation for a rational function that has a vertical asymptote at x=1 and a hole at x=3
Write the expression in algebraic form. [hint: sketch a right triangle.] tan(arcsec(x/3))
Sketch a right triangle having adjacent side(A) is given as “3”, hypotenuse side (H) is “x” and assigning angle “a” as the angle between A and H. Using Pythagorean theorem, you will get “square root of x-squared minus 9” as the opposite side (O). Using SOH CAH TOA function, and since secant is the reciprocal of cosine, sec(a) = x/3. Thus, a = arcsec(x/3). The remaining expression tan(a) is Opposite side over Adjacent side which is equal to “square root of x^2 - 9” over "3". Therefore, the algebraic expression would be: tan(arcsec(x/3)) = “sqrt (x^2 -9)” /3. Different answers can be made depending on which side you consider the “3” and “x”.

Keith's florists has 15 delivery trucks, used mainly to deliver flowers and flower arrangements in the greenville, south carolina, area. of these 15 trucks, 5 have brake problems. a sample of 4 trucks is randomly selected. what is the probability that 2 of those tested have defective brakes?
Answer:
Hence, the probability is:
0.296
Step-by-step explanation:
This can be solved with the help of the binomial probability as:
[tex]P(x=r)=n_C_rp^r(1-p)^{n-r}[/tex]
where n denote the quantity which are chosen.
r denote the quantity whose probability is to be determined or success.
and p denote the probability of success.
with n=4 since 4 trucks are randomly selected.
p=5/15=1/3 ( As 5 have brake problems out of total 15 trucks)
1-p=10/15=2/3
r=2 ( since we are asked to find the probability that 2 of those tested have defective brakes)
Hence, the probability is:
[tex]P(x=2)=4_C_2(\dfrac{1}{3})^2(\dfrac{2}{3})^2\\\\\\P(x=2)=\dfrac{4!}{2!\times (4-2)!}\times \dfrac{1}{9}\times \dfrac{4}{9}\\\\\\P(x=2)=0.296[/tex]
Hence, the probability is:
0.296
Which equation could be used to solve the problem?
Mr. Guzman drove his car 1080 miles in 6 weeks.
If he drove the same distance every week, which equation shows how far he drove each week (d)?
A.
d = 6 ÷ 1080
B.
d = 1080 – 6
C.
d = 1080 • 6
D.
d = 1080 ÷ 6
Mr. Guzman drove 1080 miles in 6 weeks. To find the distance driven each week, use the equation d = 1080 ÷ 6, which equals 180 miles per week. Therefore, the correct equation is option D.
Mr. Guzman drove 1080 miles in 6 weeks. We need to find out how far he drove each week if he drove the same distance every week.
Identify the Total Distance Driven: 1080 milesIdentify the Total Time Period: 6 weeksSet Up the Equation: Since Mr. Guzman drove the same distance every week, we use the formula:
d = Total Distance / Total Time.Substitute Known Values:
d = 1080 ÷ 6Calculate the Result:
d = 180 miles per weekThe correct equation that shows how far Mr. Guzman drove each week is d = 1080 ÷ 6, which corresponds to option D.

Clara estimates that the length of a hiking trail is 10 km. She later learns that its actual length is 12 km.
What is the percent error in Clara's estimate?
.002%
8.0%
0.2%
11.5%
Experimental value = 10 km
accepted value = 12 km
Step 1: Deduct the accepted value from the experimental value.
10 km – 12km = -2 km
Step 2: Take the absolute value of step 1
|--2km| = 2km
Step 3: Divide that answer by the accepted value. 2km/10km = 0.2%
