A car is traveling at a rate of 40 miles per hour. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 4 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.
1 mile = 1.6 kilometers
multiply 40 mph by 1.6 = 64
car's rate = 64 kilometers per hour
multiply kilometers per hour by 4 = 256
car will travel 256 kilometers in 4 hours

A protective cover for a wireless tablet has a height of 8 inches and base of 7 inches. What is the area of the cover?
Answer: The area of the cover = 56 square inches.
Step-by-step explanation:
We know that the shape of a tablet is rectangle.
Thus to calculate the area of the protective cover we apply the formula to calculate area of rectangle.
The area of rectangle is given by :-
[tex]\text{Area}=\text{Length*width}\\\\\Rightarrow\text{Area}=8\times7\\\\\Rightarrow\text{Area}=56\text{ inches}^2[/tex]
Therefore, the area of the protective cover is 56 square inches.

Richard estimates that he can apply fertilizer to 4,485 square feet of grass in 3/4 of an hour. How many square feet of grass can Richard fertilize per hour?
We know that Richard can apply fertilizer to 4485 square feet = 3/4 hour
To solve this problem, one approach is to find 1/4 then multiply by 4 to get the whole 4/4 or 1 hour.
So the solution would be:
4485/3=1495
Then multiply this by 4.
1495 multiplied by 4 is equal to 5980 square feet.
So Richard can apply fertilizer to 5980 square feet in 1 hour.

Answer:
Shifted 2 units left and 4 units up
Step-by-step explanation:
Given are two triangles
ABC is having vertices as (4,6) (7,6) and (5,9)
The transformed image A'B'C' has vertices as
(2,10) (5,10) (3,13)
On comparing the vertices corresponding we find a certain pattern.
X coordinate is reduced by 2 and y coordinate is increased by 4.
This implies the transformation is
Shifted 2 units left and 4 units up
The length of a rectangle is given by 5t+4sqrt(t), and its height is sqrt(t), where t is time in seconds and the dimensions are in centimeters. Fine the rate of change of the area of the rectangle with respect to time when the length of the rectangle is 9 centimeters.
Answer:
11.5 cm²/s
Step-by-step explanation:
We must solve two problems to answer this question:
find the time at which the length is 9 cmfind the rate of change of area with respect to time (at that time)For the first problem, we have ...
... 9 = 5t +4√t
... 9 -5t = 4√t . . . . . subtract 5t
... 81 -90t +25t² = 16t . . . . square both sides
... 25t² -106t +81 = 0 . . . subtract 16t
... (t -1)(25t -81) = 0 . . . . factor
... t = 1 or 3.24 . . . . . . t=3.24 is an extraneous solution
_____
For the second problem, we have area (a(t)) is ...
... a(t) = length×height = (5t +4√t)(√t) = 5t^(3/2) +4t
Then the derivative is ...
... a'(t) = (3/2)(5√t) +4
and
... a'(1) = (3/2)(5√1) +4 = 11.5 . . . . . cm²/s
_____

A graphing calculator can help solve both problems. It can help find the time at which length is 9 cm by solving ... length-9 = 0. (The nice thing here is that there is no extraneous solution.) It can compute the derivative of a function, too.

Jack is mowing a lawn that has a shed. Jack wants to know the area of the lawn he has to mow. here are the dimensions of the yard and the shed. 13x-4 length 5x withd shed is 2x+4length withd is 2x
find a polynomial that describes the area of the lawn he has to mow. i.e. find the area of the area of the shed.
We know that the formula for area is simply:
area = l w
where l is length and w is width
yard dimensions: l = 13x – 4, w = 5x
Ayard = (13x – 4) 5x = 65x^2 – 20x
shed dimensions: l = 2x + 4, w = 2x
Ashed = (2x + 4) 2x = 4x^2 + 8x
Therefore the area to mow is:
Amow = Ayard – Ashed
Amow = 65x^2 – 20x – (4x^2 + 8x)
Amow = 65x^2 – 20x – 4x^2 – 8x
Amow = 61x^2 – 28x

the value of the 7 in 507,264 is 10 times the value of the 7 in which number?
Answer:
The value of the 7 in 507,264 is 10 times the value of the 7 in number 2
Step-by-step explanation:
Given Number : 507,264
To find : Number in which the value of the 7 in 507,264 is 10 times the value of the 7 .
Starting from the left ,
4 is in ones place
6 is in tens place
2 is in hundreds place
7 is in thousands place
0 is in ten thousands place
5 is in lakhs place
Here, 7 is in thousands place
7000 = 10 x 700
2 is in hundreds place
200 = 2 × 100
Therefore, the value of the 7 in 507,264 is 10 times the value of the 7 in number 2 .

A six-sided rectangular box is to hold 1/2 cubic meter; what shape should the box be to minimize surface area?
A circle is an object which has the lowest surface area to volume ratio. So in this case, the shape should be like that of a circle but we cannot have a circle here because we want to form a 6 sided box. So the next thing closer to circle is a square. Hence the shape should be a square:
Answer:
square
To minimize surface area for a given volume of 1/2 cubic meter, the box should be shaped as a cube with each side measuring approximately 0.7937 meters. This cube shape offers the smallest surface area for the given volume.
Explanation:To minimize the surface area of a six-sided rectangular box with a volume of 1/2 cubic meter, it is best to make the box in the shape of a cube. This shape has the smallest surface area for a given volume. To find the dimensions of the box, let's denote the side of the cube as 's'. We know that volume V of a cube is given by V = s³. So, if the volume is 1/2 cubic meter, we have:
s³ = 1/2
s = ∛(1/2) ≈ 0.7937 meters
Each side of the cube should be approximately 0.7937 meters to achieve the minimal surface area. The surface area SA of the cube can be calculated as:
SA = 6s²
SA = 6 × (0.7937)² ≈ 3.770 meters²
Thus, a cube with sides of about 0.7937 meters will have the minimal surface area for a volume of 1/2 cubic meter.

How to determine if the function has x-axis sym, y-axis sym, and origin sym
y^2 -xy =2
To check for symmetry on the x axis, replace y with –y
-y^2 –x(-y) =2
Apply the product rule, since the equation is not identical tot eh original equation it is not symmetric about the x axis
Now do the same for y axis by replacing x with –x
Again using product rule the equations are not identical, so it is not symmetric about the y axis
To check the origin,
Replace both x & y with –x & -y
Again using product rule, the equations are not identical so it is not symmetric about the origin
To check for symmetry, replace x with -x and y with -y in the equation. Upon doing that for y^2 -xy =2, we find it lacks x-axis, y-axis, and origin symmetry.
Explanation:To determine whether a function has x-axis symmetry, y-axis symmetry, or origin symmetry, we have to replace x with -x and y with -y and see whether we get the same function.
X-axis symmetry: Replace y with -y. The equation becomes (-y)^2-(-y)x=2 which simplifies to y^2+xy=2. This is different from the original function, so there is no x-axis symmetry.Y-axis symmetry: Replace x with -x. The equation becomes y^2-(-x)y=2 which simplifies to y^2+xy=2. This is different from the original function, so there is no y-axis symmetry.Origin symmetry: Replace x with -x and y with -y. The equation becomes (-y)^2-(-y x -x)=2, which simplifies to y^2+xy=2. This is different from the original function, so there is no origin symmetry.Learn more about Symmetry of Functions here:https://brainly.com/question/16710816
