A hummingbird can travel up to 15 meters per second. What is the hummingbirds speed in miles per hour? 1 mile = 1609 meters
Answer:
33.56 miles per hour.
Step-by-step explanation:
First we will see how many meters the hummingbird can travel in an hour (in meters)
it can travel up to 15 meters per second, but we know that one hour has 3600 seconds ( because an hour has 60 minutes of 60 seconds each one ( 60 x 60 = 3600)
So the hummingbird can travel 3600 x 15 = 54,000 meters in one hour.
Now, we know that 1 mile = 1609 meters, so in order to convert the 54,000 meters in miles per hour we're going to use a rule of three.
1 mile ----------- 1609 meters
x miles ---------- 54,000 meters
x miles = 54,000/1,609 = 33.56
Therefore, the hummingbird speed is 33.56 miles per hour.
There 430 people in wave pool. Write an inequality that represents how many more people p can enter the pool.
Let
p--------> number of additional people who can enter the pool
we know that
the maximum capacity of the pool is [tex]600\ people[/tex]
so
the inequality is
[tex]430+p \leq 600[/tex]
[tex]p \leq 600-430[/tex]
[tex]p \leq 170[/tex]
the solution is the interval ----------> (-∞,170]
but remember that the number of people can't be a negative number
so
the solution is the interval -------> [0,170]
therefore
the answer is
The inequality is equal to [tex]430+p \leq 600[/tex]
To rent a bike there is a set fee, plus an hourly rate. Renting a bike for 4 hours costs $24. Renting it for 7 hours costs $37.50. How much to rent it for 3 hours?
By solving a system of linear equations, the set fee for renting a bike is determined to be $6 and the hourly rate is $4.50. Hence, the cost to rent the bike for 3 hours is $19.50.
Explanation:The question involves creating linear equations based on the given information to find the cost of renting a bike for a certain number of hours. We are told that renting a bike for 4 hours costs $24 and renting for 7 hours costs $37.50. We can express this situation with two equations, where x represents the set fee and y represents the hourly rate:
4y + x = 247y + x = 37.5We solve this system of equations to find the values of x and y. Subtracting the first equation from the second gives us 3y = 13.5, hence y = 13.5 / 3 = $4.50 per hour. We can then substitute y back into the first equation: 4(4.50) + x = 24, which simplifies to 18 + x = 24, hence x = $6.
To rent the bike for 3 hours, the cost would be 3(4.50) + 6 = $13.50 + $6 = $19.50.

Suppose that the sample space is s = {a, b, c, d, e, f, g, h} and that outcomes are equally likely. find the probability of the event e = {b, f, h}.
The probability of the event E = {b, f, h} with the sample space S = {a, b, c, d, e, f, g, h} is 3/8 or 0.375.
Explanation:The student has asked to find the probability of the event E = {b, f, h} given the sample space S = {a, b, c, d, e, f, g, h} where all outcomes are equally likely. To calculate the probability, we need to use the formula for theoretical probability, which is the number of favorable outcomes divided by the total number of possible outcomes in the sample space.
We see that the event E has 3 outcomes (b, f, h) and the sample space S has 8 outcomes. So the probability of event E is given by:
P(E) = Number of outcomes in E / Number of outcomes in S = 3 / 8 = 0.375

the function a(b) relates The area of a trapezoid with a given height of 12 and one base length of 9 with the length of its other base
The equation that represents the function B(a) as the length of the side parallel to the base is B(a) = a/6 - 9, as per the area of a trapezoid.
What is the area of a trapezoid?If the length of two parallel sides of a trapezoid is 'a', 'b' and the height of that trapezoid is 'h', then the area of a trapezoid can be represented as
= [(a + b)h]/2
Given, the base of the trapezoid is 9 and the height of the trapezoid is 12.
Therefore, 'b' is the parallel side of the base.
The given function that represents the area of the trapezoid is:
A(b) = [12(b + 9)]/2
Let, A(b) = a.
Therefore, a = [12(b + 9)]/2
⇒ 2a = 12(b + 9)
⇒ a = 6(b + 9)
⇒ a = 6b + 54
⇒ 6b = a - 54
⇒ b = (a - 54)/6
⇒ b = a/6 - 9
If we assume the length of the side parallel to the base 'b' = B(a), therefore, the equation will be:
B(a) = a/6 - 9

b.) 2
c.) 8
The expression f - 2g evaluates to -60, considering f = 4 and g = 32. The answer is not listed in the given multiple-choice options, suggesting a potential error in the question or options.
Explanation:The expression to evaluate is f - 2g. With the given values for f and g, f = 4 and g = 32, we can substitute these into the expression. The calculation will be:
f - 2g = 4 - 2(32)f - 2g = 4 - 64f - 2g = -60Therefore, the value of f - 2g is -60. This answer is not given in the multiple choice options, indicating a possible discrepancy between the question and the provided options. The correct evaluation should be confirmed.
The step function f(x) is graphed. What is the value of f(0)? -2 -1 0 1
Answer: -2 is the correct answer
Explanation:
This is the graph for greatest integer function by looking at the graph we can clearly conclude that f at zero is giving the value -2
Greatest integer function gives the value that is less than or equal to the value taken inside the function
For example if we have 2.09 and is operating under greatest integer function the value comes out to be 2 because it will convert the decimal value in integer
denoted as [2.09]=2
Jeremy saves $35 per month over the first 7 months of the year. He saves $40 per month over the next 5 months of the year. If Jeremy spends none of his savings, which expression shows how many dollars he will have saved by the end of the year?
Answer: The expression shows the number of dollars he will have saved by the end of the year is given by [tex]35(7)+40(5)=\$445[/tex]
Step-by-step explanation:
Since we have given that
Amount he saved per month over the first 7 months = $35
Amount he saved per month over the next 5 months = $40
So, total saving by the end of the year is given by
[tex]35\times 7+40\times 5\\\\=\$245+\$200\\\\=\$445[/tex]
Hence, the expression shows the number of dollars he will have saved by the end of the year is given by
[tex]35(7)+40(5)=\$445[/tex]

A. 3
B. -3
C. -12
D. 16
The result of evaluating the expression 4(2m-n)-3(2m-n) with respect to m=-15 and n=-18 is -12.
Explanation:To evaluate the expression 4(2m-n)-3(2m-n) for m=-15 and n=-18, we first substitute these given values into the expression.
Therefore, our expression becomes 4(2*(-15) - (-18)) - 3(2*(-15) - (-18)). Simplify the expression in the parentheses first according to the order of operations (also known as BEDMAS or PEMDAS) which stands for Brackets/parentheses, Exponents/Orders, Division/Multiplication, Addition/Subtraction.
4(2*-15 - (-18)) - 3(2*-15 - (-18)) simplifies to: 4(-30 +18) - 3(-30 + 18). Further simplify to: 4*-12 - 3*-12.
Then, doing the multiplication gets: -48 - (-36), which simplifies to: -48 + 36. Therefore, the value of the expression is -12.

NMO = LMO = x+34
LMO = 1/2 of LMN
so 2(x+34) = 6x-28
2x+68 = 6x-28
2x +96 = 6x
96 = 4x
x =96/4 = 24
x = 24
LMO = x+34 = 24+34 = 58
since NMO = LMO, NMO = 58

Inga lives 3 miles more than twice as far from school as Brent does. If Brent lives b miles from school then Inga lives ____ miles from school
Inga lives 2b + 3 miles from school, where b is the distance Brent lives from school in miles.
Therefore, the distance that Inga lives from school, in terms of b, is 2b + 3 miles.
Explanation:The problem states that Inga lives 3 miles more than twice the distance that Brent lives from school. If the distance Brent lives from school is b miles, this can be expressed algebraically as 2*b (twice the distance of Brent) + 3 (the extra 3 miles that Inga lives). Therefore, the distance that Inga lives from school, in terms of b, is 2b + 3 miles.
