Cory is hiking up a hill with a constant slope the double number line shows that after Cory hikes 3 km his elevation is 120 m. Select the double number line that correctly labels is option 'A'.
What do you meant by hiking?From brief half-day programs to extensive itineraries lasting more than 20 days, the activity's duration varies. The majority of the time, it is an activity that accepts groups of various sizes.
A long stroll, especially one undertaken for the sake of recreation or exercise; see also hike; an increase, particularly in quantity or amount. While it is entirely up to each hiker to assign whatever classification they see fit to their experience, I have found that the vast majority of hikers fall into one of the three most common categories: peak-bagging, long-distance hiking, or day hiking.
Because it is a constant slope and Cory hikes 3 km his elevation is 120 m.
slpoe = 120m/3km = 40m/1km
So, Cory's elevation after he hikes 1 km, his elevation is 40 m.
Cory's elevation after he hikes 2 km, his elevation is (2*40 m) 80 m.
Cory's elevation after he hikes 4 km, his elevation is (4*40 m) 160 m.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly.After 11months he weighed 140 Kilograms. He gained weight at rate of 5.5 kilograms per month.
Let y represent the sumo wrestler’s weight (in kilograms)after x month.
Complete the equation for the relationship between the weight and number of months.
The equation that shows the relationship between the weight and number of months. y = 79.5 + 5.5x
What is weight ?In science and technology, the weight of an object is the force acting on an object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on an object. Others define weight as a scalar quantity, the magnitude of gravitational force. Still others define it as the size of the reaction force applied to the body by mechanisms resisting the influence of gravity: weight is a quantity measured, for example, by a spring balance.
Given that ; Total Month = 11 months
Gained weight at the rate = 5.5 kilograms per month.
Assume initial weight W,
The initial weight + total month x rate = 140
w + 11 x 5.5 = 140
w = 79.5
if y is total weight after x months
y = 79.5 + 5.5x

3. ) Copy Center charges $0. 08 a page for machine fed copies and $0. 20 per page for hand-fed copies. I lagan's
bill for 80 copies of his movie script is $13. 00, how many copies of each type were made?
The number of machine fed copies are 25 and the number of hand fed copies are 55. This is solved forming simultaneous equations.
What are simultaneous equations?
Two or more algebraic equations that share variables, such as x and y, are said to be simultaneous equations. Since the equations are solved simultaneously, they are known as simultaneous equations. These equations alone could have an infinite number of solutions.
Given cost per page of machine fed copies = $0.08
cost per page of hand fed copies = $0.20
Let,
number of machine fed copies = x
number of hand fed copies = y
Given the total number of copies = 80
So we can write the equation as
x + y = 80 ⇒ (1)
It is also given that the total cost of the movie script is $13
So we can the equation as
0.08x + 0.20y = 13 ⇒ (2)
Solving the simultaneous equations (1) and (2)
From (1),
x = 80 - y
Substituting the above in (2)
0.08(80 - y) + 0.20y = 13
0.12y = 6.6
y = 55
x = 80 - 55 = 25
Therefore the number of machine fed copies are 25 and the number of hand fed copies are 55.

Which expression is not equivalent to logp 36? 1. 6 log 2 2. log 9+ Iog, 4 O 3 2 logb 6 4. log 72 logp 2
log 30+ log 6 is not equivalent to log 36
What is equivalent expressions?Equivalent expressions are expressions that perform the same function not with standing their appearance. If two algebraic expressions are equivalent, they have the same value when the same value(s) for the variable are used (s).
The original phrase is as follows
Log 36
Following that, we write the alternatives (a) log 2+ log 18
Apply the logarithmic rule log 2+ log 18 log (218)
Log 2 plus log 18 log (36)
Remove the bracket
Log 2 plus log 18 log36
(a) Log 2+ Log 18 is the same as log 36.
(b) Log 30 plus log 6
Use the logarithms’ law. 30 logs or more 6 logs (30 x 6)
Log 30 plus log 6 Equals log (180)
Remove the bracket
Log 30-plus log 6-log180
Hence,
(c) Log 30+log 6 does not equal log 36.

A horse walks 4224 feet in 12 minutes at this rate how many yards does a horse walk in twelve minutes.
Answer:
1408 yards
Step-by-step explanation:
A horse walks 4224 feet in 12 minutes, so to find out how many yards the horse walks in twelve minutes, we need to convert 4224 feet to yards. Since there are 3 feet in a yard, we can divide 4224 by 3 to find the number of yards:
4224 feet / 3 feet/yard = 1408 yards
So a horse walks 1408 yards in 12 minutes.

Seacausus stadium has a seating capacity for 25,000 spectators. The stadium has 25 exits and can be vacated in 20 minutes. The time taken to exit the stadium varies directly with the number of spectators and inversely with the number of exits. Determine the time taken for 21,000 spectators to vacate the stadium, if only 15 exits are functional.
The time taken for 21,000 spectators to vacate the stadium, if only 15 exits are functional is 28 minutes
How to determine the time taken for 21,000 spectators to vacate the stadium?
A variation is a relation between a set of values of one variable and a set of values of other variables
Let E, N and T represent the number of exits, the number of spectators and the time taken to exit the stadium respectively
We can write the variation as:
T α N/E
T = kN/E (where k is constant of proportionality)
when N = 25,000, E = 25, T = 20:
T = kN/E
k = TE/N
k = (20×25)/25000 = 0.02
when N = 21,000 and E = 15:
T = kN/E
T = (0.02×21,000)/15 = 28 minutes

a) 3.2 ÷ 0.8 = ? please explain how you got it and b) 7.5 ÷ 0.5 also please explain how you got it i'll give the brain thing
Answer: To solve a division problem of the form a ÷ b = c, you need to find the value of c that makes the equation true. This means that if you multiply b by c, the result should be equal to a.
a) In the problem 3.2 ÷ 0.8 = ?, we are looking for the value of c that makes the equation true.
To solve this problem, we can multiply 0.8 by c to find the value of c that makes the equation true:
0.8 * c = 3.2
Dividing both sides of the equation by 0.8, we get:
c = 4
Therefore, the value of c that makes the equation 3.2 ÷ 0.8 = ? true is 4.
b) In the problem 7.5 ÷ 0.5 = ?, we are looking for the value of c that makes the equation true.
To solve this problem, we can multiply 0.5 by c to find the value of c that makes the equation true:
0.5 * c = 7.5
Dividing both sides of the equation by 0.5, we get:
c = 15
Therefore, the value of c that makes the equation 7.5 ÷ 0.5 = ? true is 15.

Step-by-step explanation:
Solve for x. The triangles in each pair are similar.
Apply arithmetic operations on both sides of the equation to move the variable to one side and all other values to the opposite side.
How Do You Solve for x?Let's begin with a basic equation: x + 2 = 7.
How may x be obtained on its own?
x + 2 - 2 = 7 - 2 x = 5 after deducting 2 from both sides.
Put the solution, x = 5, back into the equation to confirm it. We get 5 + 2= 7.
Since LHS = RHS
In the triangle, find x.
Use triangle properties or the Pythagorean theorem to find the value of x, the unknown side or angle in a triangle.
Let's use an example to better understand how to solve for x in a triangle.
Using the Pythagorean theorem, we obtain AC2 = AB2 + BC2 where x2 = 72 + 242 x = 49 + 576 x = 625 x = 25 units.

Barry wants to host an event at a hotel that has four conference rooms. Each conference room has a maximum capacity of 150 people, but the
hotel limits the capacity to 1 person for every 4 square feet.
Sketches of the four conference rooms are shown below. Which room will stop Barry from hosting the event at the hotel?
25 ft
24 ft
28 ft
28 ft
The room that would stop Barry from hosting the event is the semicircular room.
Which room has a capacity that is less than 1 person per 4 square feet?Would the first rectangular room allow Barry have the meeting?
The first step is to determine the area of the room
Area of a rectangle = length x width
25 x 30 = 750 feet²
Number of people per square foot - 750 / 150 = 1 person for every 5 feet
Would the trapezoidal room allow Barry have the meeting?
The first step is to determine the area of the room
Area of a trapezoid = 1/2 x (sum of parallel sides) x height
1/2 x (24 + 36) x 28 = 840 feet²
Number of people per square foot = 840 / 150 = 1 person for every 5.6 feet
Would the square room allow Barry have the meeting?
The first step is to determine the area of the room
Area of a square = length x width
28 x 28 = 784 feet²
Number of people per square foot - 784 / 150 = 1 person for every 5.2 feet
Would the semi circular room allow Barry have the meeting?
The first step is to determine the area of the room
Area of a semicircle = 1/2πr²
Where:
r = 3.14
r = radius = diameter / 2 = 28 / 2 = 14 feet
1/2 x 3.14 x 14² = 307.72 feet²
