Answer:87.5
Step-by-step explanation: I can find the total cost of a 5 hire bike tour because I'm given the unit rate and the amount of time to multiply it by.
The total cost of the five hours bike tour is $87.50
Cost of equipment = $50
Cost per hour = $7.50 per hour
The total cost of the equipment for five hours will be the addition of the fixed cost and the variable cost. This will be:
= $50 + $7.50h
where, h = number of hours = 5 hours
Total cost = $50 + $7.50(h)
= $50 + $7.50(5)
= $50 + $37.50
= $87.50
The total cost of the five hours bike tour is $87.50

At Dairy Freeze, 2 of the last 10 sundaes sold had nuts. Considering this data, how many of the next 20 sundaes sold would you expect to have nuts?
Answer: 4
Step-by-step explanation:
By finding the relative frequency, we will see that we can expect that 4 out of the next 20 sundaes will have nuts.
How many of the next 20 sundaes can we expect to have nuts?
First, we know that 2 out of the last 10 sundaes sold had nuts. So the relative frequency of sundaes with nuts is:
R = 2/10 = 0.2
(the quotient between the number of sundaes with nuts and the total number of sundaes)
Then, out of the next 20 sundaes, we can expect that the number of sundaes with nuts will be:
N = R*20 = 0.2*20 = 4

B. 3x^3 +3^3
C. 2x^3 + x^2 - 4x - 2x^3 +1
D. x^2+x+1
Answer:
Option D.
Its a Polynomial or Binomial of index 2
Someone pleaseeee answer
Answer:
A
Step-by-step explanation:
We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.
5x ≥ 0 implies that x ≥ 0x + 3 ≥ 0 implies that x ≥ -3Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.
Consider the diagram.
Which equations are true? Select all true equations.
Answer:
Sum of angles of a triangle is 180, so x + y + w = 180
Straight angle is 180 , so y + z = 180
From the first 2 conditions :
=>x + y +w = y + z
=> x + w = z
Option 1, 2, 5
The equations which are true are given by,
w + x + y = 180w + x + y = 180y + z = w + x + yw + x + y = 180y + z = w + x + yw + x = z What is an Equation?Equation is a mathematical relation between more than one variable, number or mathematical quantities involving mathematical operations using equal sign in between them.
From angle sum property of triangle says that the sum of all interrior angles of a triangle is 180.
Here all interrior angles of triangle are x,y,w
So, x+y+w = 180
Hence first option is correct.
Again the exterrior angle of a triangle is equal to the sum of the opposite two interrior angles.
here exterrior angle is z and opposite two interrior of z are x,w
So, w+x = z
Hence last option is correct.
Again y+z = y+w+x
so second option is also true.
Hence correct options or equations are given by:
w + x + y = 180w + x + y = 180y + z = w + x + yw + x + y = 180y + z = w + x + yw + x = zLearn more about Equation here -

PLEASE HELP PLEASE HELP
Answer:
B) 24
Step-by-step explanation:
The area of the rectangle is 48 units (8 x 6).
The base of the is 6 units and the height is 8 units. The formula for the are of a triangle is A = [tex]\frac{1}{2}[/tex]bh.
b = base
h = height
A = [tex]\frac{1}{2}[/tex](6)(8)
A = 24
Answer:
[tex]24[/tex]
Step-by-step explanation:
If the area of a rectangle is bh, and the area of a triangle is bh/2, then a triangle's area is half a rectangle's area. Hence, if the area of the rectangle is 48, the area of the triangle is half of 48, or 24.

the equation for the ellipse given is 4x^2+9y^2-16x+18y-11
Answer:
a. a = 3, b = 2
b. The coordinate of the center is (2, -1)
c. The eccentricity of the ellipse is √5/3
d. Please see attached graph of the ellipse created with MS Excel
Step-by-step explanation:
7. a. The given equation of the ellipse is presented as follows;
4·x² + 9·y² - 16·x + 18·y - 11
The general equation of an ellipse
[tex]\dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1[/tex]
We can write;
4·x² - 16·x + 9·y² + 18·y - 11
4·(x² - 4·x + 4) + 9·(y² + 2·y + 1) - 25 - 11
4·(x² - 4·x + 4) + 9·(y² + 2·y + 1) = 25 + 11 = 36
4·(x - 2)² + 9·(y + 1)² = 36
[tex]\dfrac{4\cdot (x - 2)^2}{36} + \dfrac{9 \cdot (y + 1)^2}{36} = \dfrac{36}{36}[/tex]
[tex]\therefore \dfrac{ (x - 2)^2}{9} + \dfrac{ (y + 1)^2}{4} = \dfrac{ (x - 2)^2}{3^2} + \dfrac{ (y + 1)^2}{2^2} = 1[/tex]
By comparison, a = 3, b = 2, h = 2, k = -1
b. The coordinate of the center, (h, k) = (2, -1)
c. The eccentricity of the ellipse = c/a
c² = a² - b²
∴ c² = 3² - 2² = 5
c = √5
Eccentricity = √5/3
d. Please find attached the graph of the ellipse created with MS Excel

m < [?] OR m >[]
Enter
Answer:
[tex]:\implies \boxed{\red{\sf m \in (-1,-\infty)}}[/tex]
Step-by-step explanation:
Given :-
A linear inequality 4m +6<2We need to find the solution set for the given inequality . So , on solving it , we have ,
[tex]:\implies[/tex] 4m + 6 < 2
[tex]:\implies[/tex] 4m < 2 - 6
[tex]:\implies[/tex] 4m < -4
[tex]:\implies[/tex] m < -4/4
[tex]:\implies[/tex] m < -1
Hence m can have all values less than -1. Therefore the final answer is ,
[tex]:\implies \boxed{\red{\sf m \in (-1,-\infty)}}[/tex]
Hence m can have all values less than-1.
