2. An Evergreen Eagle flies about 13 meters in one second. How many kilometers could it fly in 20 minutes? *
Answer:
Evergreen Eagle can will fly 1.56 km in 20 minutes.
Step-by-step explanation:
Speed of Evergreen Eagle = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
= [tex]\frac{13}{1}[/tex]
= 13 meters per second
With this speed Eagle can fly the distance in 20 minutes Or 120 seconds
= Speed × Time
= 13 × 120
= 1560 meters
Since, 1000 meters = 1 Km
1 meter = [tex]\frac{1}{1000}[/tex] km
Therefore, 1560 meters = [tex]\frac{1560}{1000}[/tex]
= 1.56 km
Therefore, Evergreen Eagle can will fly 1.56 km in 20 minutes.

To solve this problem use proportions. The tree's proportion is equal to [tex]\frac{30}{40}[/tex] and the shed's proportion is [tex]\frac{15}{x}[/tex]. These proportions are made by putting the height of the object over the length of the shadow. Then, cross multiply to find x. Do this by multiplying [tex]30 *x[/tex] and [tex]40*15[/tex]. Next set these equal to each other, [tex]30x=600[/tex]. Finally, divide both sides by 30 to find x. This equals 20 feet.

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and the area of the rug
Answer:
Width = 1/2h
Area = 1/4h²
Step-by-step explanation:
This is quite a vague question from you. Being asked to find the width and area of a particular shape, without being given dimensions.
However, I would try to solve it nonetheless.
From your question, you stated that the width of the rug is half its height, if so, then,
w = 1/2h
Again, you're being asked to find the area. Area of a kite is given as
Area = 1/2 * Width * Height and as such, we have
Area = 1/2 * 1/2h * h
Area = 1/4 * h²
All that you need to do now is substitute the value of h

Drag each graph to the correct location on the table.
The points on the graphs represent relations. Classify these relations according to whether or not they are functions
Answer:
Functions: Second Graph
Not functions: first and third graph
Step-by-step explanation:
The first and third graph are not functions and the second graph is a function. Use the vertical line test. I'm 100% sure.
By the vertical line test, it's clear that graph first will not be a function, second will be a function and third will also not be a function.
What is the e-test?A vertical line test is a test to determine whether a given function is a function or not.
In the vertical line test, we draw a vertical line on every x's point if the line intersects with only a single value of corresponding y then it will be a function otherwise not.
In the first given function if we draw a vertical line at x = 2 then it gave different values corresponding to y hence, it will not a graph.
In the second given function by drawing a vertical line, it gave a single unique value so it will be a function.
In the third given function if we draw a vertical line at x = 1 and 2 then it gives different values corresponding to y hence, it will not be a graph.

You go to the hardware store to pick out some tile. You find ones that you like. There are 4 sizes of tile and are priced differently. The prices are 1 square inch tile is 10 cents, 6 square inch tile is 25 cents, 8 square inch tile is 75 cents and 18 square inch tile is $1.50. Find the best deal (price) for tile in order to tile your bathroom. How much will you spend? Why is this the best deal? Show ALL OF YOUR WORK and explain how you found the answer.

Step-by-step explanation:
Jivesh brought his Model B rocket on a camping trip near the top of a mountain. He wants to model how it descends down the mountain. Here, he uses the equation h = −640t^2. When has the rocket descended 1,690 centimeters? Round your answers to the nearest hundredth. After t ≈ seconds, the rocket will have descended a distance of 1,690 centimeters. The negative time (can, cannot) be used in this context.
Answer:
i. 1.63 s
ii. The negative time cannot be used in this context
Step-by-step explanation:
i. Since h = −640t² and the rocket descends 1,690 m, h = -1,690 m (since there is a drop in height).
So, h = -640t²
t² = h/-640
t = √(- h/640)
Substituting h into the equation, we have
t = √(- h/640)
t = √[-(-1,690)/640]
t = √2.640625
t = 1.625
t ≈ 1.63 s
ii. So, the negative time cannot be used in this context because, the height drop is negative.

A major credit card company requires monthly payments equal to or greater than 8% of the total balance.A consumer has a credit card balance of $320. Write an inequality that represents acceptable payment amounts.
Answer:
320 x 0.08 = X
In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Step-by-step explanation:
Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:
320 x 0.08 = X
25.6 = X
Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

What's the equation
Given:
The graph of a parabola.
To find:
The equation for the parabola.
Solution:
The vertex form of a parabola is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where, a is a constant and (h,k) is the vertex.
From the given graph it is clear that the vertex of the parabola is at point (-1,6). So, h=-1 and k=6.
Putting h=-1 and k=6 in (i), we get
[tex]y=a(x-(-1))^2+(6)[/tex]
[tex]y=a(x+1)^2+6[/tex] ...(ii)
The y-intercept of the graph is at point (0,3). Putting x=0 and y=3 in (ii), we get
[tex]3=a(0+1)^2+6[/tex]
[tex]3-6=a[/tex]
[tex]-3=a[/tex]
Putting a=-3 in (ii), we get
[tex]y=-3(x+1)^2+6[/tex]
Therefore, the equation of the parabola is [tex]y=-3(x+1)^2+6[/tex].
v) Find the perimeter of the rectangle whose length is 60m and breadth is 55m
vi) Find the perimeter of a square room with side equal to 8m each.
Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
