A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal? 31 units 39 units 41 units 49 units
Answer: 41 units
Step-by-step explanation: took the quiz
The length of the diagonal is 41 units.
To find the length of a diagonal.
What is rectangle?A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.
Let a right triangle with legs length 9 units and 40 units and hypotenuse is the diagonal length c.
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]9^{2} +40^{2} =c^{2}[/tex]
[tex]81+1600=c^2\\1681=c^2[/tex]
sqrt both sides
41=c
So, the length of the diagonal is 41 units.

I need to know which ones are nonlinear or nonproportion
Nonlinear means that -- the graph isn't exactly the line. It's basically a "curve" like parabola.
Non-proportional means that --- the graph doesn't start from the origin point or doesn't start at (0,0).
( A ) is both linear and proportion.
( B ) is proportion BUT NOT LINEAR (It's curved.)
( C ) is linear and proportion.
( D ) Is linear BUT NOT PROPORTION (Doesn't start at (0,0) )
So ( B ) and ( D )

Danielle and David will run in a marathon. Danielle's running pace is 7 miles per hour, and David's is 4 miles per hour. If they both start at the same point, how many
minutes should it take Danielle to be mile ahead of David?
Answer:
I believe it is 20 minutes.
Step-by-step explanation:
It takes 1 hour for Danielle to run 3 miles ahead of David. You would have to divide 3 hours by 3 which is 1 mile. You have to do the same for the time it took to run 3 miles ahead (1 hour). 1 hour = 60 minutes and 60 divided by 3 is 20. This means it should take Danielle 20 minutes to be 1 mile ahead of David.
Hope this explanation helps!
Answer:
10 minutes
Step-by-step explanation:
I've had the same question, and although the other answer was correct, the question asked how long it would take to be 1/2 mile ahead, so I guess you'd do 20 divided by 2 in order to get the correct answer. Hopefully this helps you, if not, ignore me :)

What is the sum of three consecutive whole numbers with 4y as the middle whole number?
please answer
=====================================================
Explanation:
4y is the middle value, or second value.
This means 4y-1 is the first value since it is immediately before 4y
Also, we know that 4y+1 is the value just after 4y
The order of the terms is: 4y-1, 4y, 4y+1
Add up those three expressions and simplify
(4y-1) + (4y) + (4y+1)
4y-1 + 4y + 4y+1
(4y+4y+4y) + (-1+1)
12y+0
12y
The three terms combine to 12y.

What is the best estimate of the area of the figure if each square has an area of 4 cm2? On a coordinate plane, a figure contains 30 squares. 30 cm2 46 cm2 92 cm2 118 cm2
Answer: its not 30cm2
Step-by-step explanation:
The best estimate of the area of the figure is 120 cm², which is closest to option D.
How to calculate the area?From the image, we can see that the figure contains 30 squares, and each square has an area of 4 cm².
Therefore, the total area of the figure can be estimated by multiplying the number of squares by the area of each square:
Total area = Number of squares × Area of each square
Total area = 30 squares × 4 cm²/square
Total area = 120 cm²
So, the best estimate of the area of the figure is 120 cm², which is closest to option D.

which two integers is square root 102 between? please help
Answer:
√120 - 10 and 11Step-by-step explanation:
The square root of numbers refers to a value that when multiplied by itself, the answer is the original number. However, most numbers are non-perfect square, meaning their square roots are decimal numbers.
For non-perfect square numbers, the easiest way to get their square root is by the use of a calculator. But if there is no available calculator, there is also a way to find in which two consecutive integers their square root lies.
Find the nearest lower perfect square number.
Give the square root of the nearest lower perfect square number.
The two integers are the square root of it and the next number to it.
Let us now answer the given above by following these steps.
√120 - 10 and 11
The nearest lower perfect square number is 100.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = 9x² + 24x + 16
On factorizing the equation , we get
A = ( 3x + 4 )²
On simplifying , we get
A = ( 3x + 4 ) ( 3x + 4 )
A = 3x ( 3x + 4 ) + 4 ( 3x + 4 )
A = 9x² + 12x + 12x + 16
On further simplification , we get
A = 9x² + 24x + 16
Hence , the value of the expression is A = 9x² + 24x + 16
