Every autumn, the North American Monarch
butterfly migrates up to 3,000 miles to California and Mexico where it hibernates
until early spring. The butterfly travels on average 50 miles per day.
Part A
The equation is d = 50t
This is because the slope of 50 represents how many miles per day the butterflies cover (on average). The y intercept is 0 to indicate that 0 miles have been traveled initially.
You can think of this as the equation y = 50x
If t = 1, then d = 50t = 50*1 = 50 miles have been covered
If t = 2, then d = 50t = 50*2 = 100 miles have been covered
And so on.
==========================================================
Part B
You'll have these values in the bottom row (in the order presented): 50, 100, 150, 200, 250
You can plug in the values t = 1, t = 2, t = 3, t = 4 and t = 5 into d = 50t to find those answers in bold.
Or you could add on 50 each time to generate each new value. We start at 50 since t = 1 corresponds to d = 50.
==========================================================
Part C
You can keep the pattern of 50,100,150, ... going until you reach 2500. Then note the t value that pairs with d = 2500
In my opinion, that's the slower method.
The quicker method is to plug d = 2500 into the equation for part A, and then solve for t.
d = 50t
2500 = 50t
50t = 2500
50t/50 = 2500/50 ....... divide both sides by 50
t = 50
It will take 50 days for the average distance traveled to be 2500 miles.
A right triangle has legs with lengths of 6in and 8in. What is the length of the hypotenuse
Answer: 10
Step-by-step explanation:
the formula is √a^2+b^2=c^2
so your equation should look like this √6^2+8^2=c^2
6·6=36
8·8=64
√36+64
√100=10
the hypotenuse or c^2 is 10

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2

A cyclist rides a distance of 36 km at an average speed of 16 km/h.
Calculate the time taken to complete this ride. Give your answer in hours and minutes.
Please Help!
Answer:
2.25 hours, or 2 hours and 15 minutes.
Step-by-step explanation:
All we do is 36/16 which is 2.25. 0.25 or 1/4 of an hour is 15 minutes. So, your answer is 2 hours and 15 minutes.
It takes 2 hour and 12 minutes for the cyclist to complete the ride of 36km distance.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Total distance covered by cyclist= 36km
Average speed of the cyclist = 16km/hr
Therefore, using unitary method:
16 km distance takes time = 1hr
Therefore, 1 km distance takes time =(1/16)hr
Therefore, 36 km distance takes time = (1/16)×36 hr
=(1/4)×9 hr
=9/4 hr
=2.25 hr
=(2+0.25)hr
=2hr+0.25hr
=2hr+0.25×60minutes
=2hr and 15 minutes.
Hence, it takes 2hr and 15 minutes for the cyclist to complete 36 km rides.

The bronx zoo opened at 9.00 am. In the first hour 280 people purchased admission tickets. In the second hour 25 percent more people purchased admission people than the first hour . Each ticket cost 16.25. What was the total amount of money paid for all the tickets purchased in the first two hours
Answer:
Total amount paid for tickets in the two hours = $10,237.50
Step-by-step explanation:
Step 1
Ist Hour, 280 tickets were sold at the cost of $16.25
Amount of money made in the first hour= Number of people who purchased ticket x price of a ticket
=280 x 16.25 =$4,550
2nd Hour, 25 % more people purchased ,
which means the total number of people who purchased tickets =
1.25 x 280= 350
Amount of money made in second hour = Number of people who purchased ticket x price of a ticket 350 x 16.25 =$5,687.5
Step 2
Total amount paid for tickets in the two hours = Amount of money made in the first hour +Amount of money made in second hour
=$4,550+ $5,687.5
=$10,237.50

Answer:
1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.
2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

What is the best approximation of the solution to the system to
the nearest integer values?
o
(3, 4)
o
(2, 3)
O (1, 3)
o (3, 2)
Answer: (2,3)
====================================================
Explanation:
The intersection point of the two lines is where the solution point is located.
The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.
At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.
So that's how we get to (2,3)
What single transformation was applied to triangle A to get triangle B?
Answer:
should be reflection
Step-by-step explanation:
bc a translation would just move it and rotation and dilation wouldn't work either
The single transformation was applied to triangle A to get triangle B is a reflection, in which A is reflected around the y-axis.
What is reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.
Given:
The triangles A and B are shown in the given figure,
Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original,
Rotation is the process of going around a center.
A shape is translated when it is moved up, down, left, or right without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes.
Thus, triangle A is reflected as B.

Find the sine, cosine, and tangent of angle A. (fraction as in simplest form please.)
Answer:
SinA=3/5
CosA=4/5
TanA=3/4
Step-by-step explanation:
first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2
20^2-16^2=144 the square root of 144 is 12 so side length bc=12
so sin is opposite/hypotenuse
the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5
cos is adjacent/hypotenuse
the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5
tan is the opposite/adjacent
the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4
