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.

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.
√100 = 10

(d). < 20
The measure of the third side of the triangle is < 20, the correct option is D.
What is an Isosceles Triangle?An Isosceles triangle is a triangle whose two sides are equal in length, and so two angles are also equal in measure.
The isosceles triangle has equal side of 10.
According to the theorem,
The length of the third side is always less than the sum of the two sides of a triangle.
Let the third side be x
Then,
x < 10+10
x < 20

What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A company manufactures acoustic guitars.
The table shows the number of units that the company sold each month over a nine-month period beginning in January, that is;
Month, x 1 2 3 4 5 6 7 8 9
Units, y 150 300 380 425 425 480 520 550 575
If we put x = 2
[tex]y = 148.4 \sqrt {2-1} +154\\\\y = 148.4 +154 = 302.4[/tex]
Y = 300 ( approx)
We can see that the equation that models the situation;

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 :)

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.
