A car travels 2/5 mile in 1/2 minute. what is the cars speed in miles per hour?
The speed of the car is 48 miles per hour, based on the given information that the car travels 2/5 miles in 1/2 minute.
Explanation:To solve this problem, we first need to recognize that the car has traveled 2/5 miles in 1/2 minute. To calculate the speed in miles per hour (mph), we need to find how far the car would go in 1 hour. In other words, how many 1/2 minutes are there in an hour? An hour has 60 minutes, so there are 2*60=120 half-minutes in an hour. If the car travels 2/5 mile in each half minute, then in one hour (or 120 half-minutes), the car would travel 2/5*120=48 miles. Consequently, the car's speed is 48 miles per hour.

Given cos B = 11/18 find angle B in degrees. Round your answer to the nearest hundredth.
Answer:
[tex]B\approx 52.33^{\circ}[/tex]
Step-by-step explanation:
We have been given that [tex]\text{cos}(B)=\frac{11}{18}[/tex]. We are asked to find the measure of angle B.
We will use inverse cosine or arccos to solve for the measure of angle B as:
[tex]B=\text{cos}^{-1}(\frac{11}{18})[/tex]
[tex]B=52.33011303567^{\circ}[/tex]
Upon rounding our answer to nearest hundredth, we will get:
[tex]B\approx 52.33^{\circ}[/tex]
Therefore, the measure of angle B is 52.33 degrees.
Write the equation is logarithmic form
33 = 27
A.
log 27 = 3
B.
log327=27
C.
log327 = 3
D.
log 27 = 3 · 3
Final answer:
The correct logarithmic form of the equation 3³ = 27 is log3(27) = 3, which matches option C, showing that the exponent to which the base 3 must be raised to get 27 is 3.
Explanation:
The question asks to express the equality 3³ = 27 in logarithmic form. By definition, the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number.
Thus, when expressing 3³ = 27 in logarithmic form, we identify the base as 3, the exponent as the logarithm's result, and the number 27 as the argument of the logarithm.
Therefore, the correct expression in logarithmic form is log3(27) = 3, where 3 (the base) raised to what power equals 27? The answer is 3, making option C correct.

The bear population increases at a rated of 2% each year. There are 1573 bears this year. What is the growth factor, b?
To find the growth factor, b, we can use the formula for exponential growth: n = ln(M)/ln(b), where n is the number of years, M is the final population, and b is the growth factor.
Explanation:To find the growth factor, b, we can use the formula for exponential growth: n = ln(M)/ln(b), where n is the number of years, M is the final population, and b is the growth factor. In this case, the final population is 1573 bears. Let's solve for b: n = ln(1573)/ln(b). To isolate b, we can take the exponential of both sides: b^n = 1573. Now we can solve for b by taking the nth root of 1573. The growth factor, b, is the value that, when raised to the power of the number of years, gives us the final population of bears.
Over the weekend, Statton and Tyler drove to Montana to go hunting. Now they're preparing to go home. Tyler needs gas for his jeep, which gets 22 miles per gallon for gas mileage. When he stops at the gas station, he already has 5 gallons of gas in his tank. he buys more gas for $1.25 per gallon if Tyler spends 22 on gas what is the total distance the boys could travel round if necessary to the nearest tenth
he bought : 22/1.25 = 17.6 gallons
17.6 +5 = 22.6 gallons total

A lab found that 670 rats could run through a maze in a mean time of 4.7 seconds. What is the 99% confidence interval for the population mean? Use the formula for margin of error: z•σ/√n. Please explain each step, particularly how to find the population standard deviation.
Using the formula for margin of error as
MOE = z * σ / √n
would be very difficult since we are not given the value of the standard deviation. Standard deviation value must be given since it is obtained from the experiment.
However, we use another formula for MOE in the form of:
MOE = z sqrt [p (1 – p) / n]
where p is the proportion at 99% confidence interval at z crit value. From the standard distribution tables, this corresponds to a p value of:
z crit = 2.58
p = 0.9951
Therefore the margin of error is:
MOE = 2.58 sqrt [0.9951 (1 – 0.9951) / 670]
MOE = 6.96 x 10^-3 = 0.00696 s
We can see that at 99% Confidence interval, the Margin of Error is extremely small (almost 0). For the sake of calculation:
Confidence interval = 4.7 s ± 0.00696 s
Confidence interval = 4.69304, 4.70696
Which of the following is true of the location of the terminal side of an angle 0 who's sine value is 1/2?
0 has a reference angle of 30° and is in quadrant one or two
0 as a reference angle 30° and is in quadrant one or four
0 has a reference angle of 60° and is in quadrant one or two
0 as a reference angle of 60° in is in quadrant one or four
Answer:
A) 0 has a reference angle of 30° and is in quadrant one or two
Step-by-step explanation:
Given :
Terminal side of an angle = 0
Therefore, the terminal side is the x-axis.
sin = 1/2
Sin value is 1/2 when it is 30 degrees.
In the quadrant I and II, the sine value must be positive.
Therefore, the answer is A) 0 has a reference angle of 30° and is in quadrant one or two
Hope this will helpful.
Thank you.
The true statement of the location of the terminal side of an angle is that 0 has a reference angle of 30° and is in Quadrant I or II
What is Standard Position?It is known to be an angle which is said to be in the same or standard position only when its vertex is seen at the center and one ray is seen in the positive x-axis. The ray seen on the x-axis is known to be the first or initial side and the second or other ray is known to be the terminal side.
Based on the above, the Terminal side of an angle is known as 0
and Sin (theta) = ½
The Basic angle was given as 30
So we say 180-30 = 150
We say that the terminal side is the x-axis = sin = 1/2
So therefore, Sin as 1/2 only if it is 30 degrees and In the quadrant I and II, the sine value have to be positive value.
Therefore, the option A where 0 has a reference angle of 30° and is in quadrant one or two is correct.
