Please Help! If (3x+5)^2=ax^2+bx+c, what is the value of a+b+c?
Answer:
64
Step-by-step explanation:
You open up the (3x+5)^2 and get:
9x^2 + 30x + 25
So...
a+b+c = 64
OR
You add the coefficient(s) and the constant together in the parentheses and get:
(3x+5)^2 --> (8)^2
So you square the 8 and get:
64

Answer:
x = 39
Step-by-step explanation:
there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two
so, (36 + 42)/2 = x
36 + 42 = 78
78/2 = 39
Solve each system of equations by substitution.
2x + 2y = 3 x - 4y = -1
Step-by-step explanation:
2x + 2y = 3 ( x2 for everything in the equation)
x - 4y = -1
4x+ 4y = 6
x - 4y = -1
Add the 1st line to the 2nd line to get rid of the y:
5x = 5
x - 4y = -1 ( you can pick any line from this system to be the second equation in this step, you can put 2x + 2y = 3 or 4x+ 4y = 6, anything above this step, but to make it simple chose the one you think is the easiest)
Solve for x, then plug the x value into the 2nd equation
x = 1
1 - 4y = -1
x = 1
-4y = -2 =) y = 1/2
x = 1
y= 1/2
which is the answer

An electric powered fan has a 9 inch diameter blade that
rotates at 4000 revolutions per minute.
Find the angular speed of the sword in radians per minute.
_____/-\radians/minute
The speed of the fan is 1884 inches per second.
Step-by-step explanation:
Revolution per minute= 4000
Radius = 4.5 inches
Circumference= 2π r
= 2(3.14) (4.5)
= 28.26 inches
1 revolution= 28.26 inches
4000 revolution= (28.26) (4000)
=113040 inches per minute
= 113040/60
= 1884 inches per second
The speed of the fan is 1884 inches per second.
Final answer:
To find the angular speed of a fan blade given its revolution per minute, multiply the revolutions per minute by 2π to get the angular speed in radians per minute.
Explanation:
An electric powered fan has a 9-inch diameter blade rotating at 4000 revolutions per minute. To find the angular speed in radians per minute, we can use the formula: Angular speed (in rad/min) = (revolutions per minute) x 2π. Therefore, angular speed = 4000 x 2 x π = 8000π rad/min. So, the angular speed of the fan blade is 8000π radians per minute.

What equation can you use to find the value of x?
2x + 3x + 50 = 360
2x + 3x + 50 = 180
2x + 3x = 50
Answer:
I know I am late to answer but here is the right answer
X=26
Step-by-step explanation:
since 2x and 3x are on the same side of the equation you can combine the to get 5x+50=180. Then you subtract 50 from both sides of the equation witch you would get 5x on one side of the equation and 130 on the other. The you would divide 5x from both sides. 5x and 5 cancel out so you are left with 130 divide by 5x. You the divide which gives you the answer of X=26.

Chromosomes contain one or more genes.
Answer:
D. Chromosomes contain one or more genes (really, they contain thousands.)
Step-by-step explanation:
The definition of a chromosome is a segment of DNA that contains a certain gene, which then codes for a protein.
Why not A: Chromosomes contain genes.Why not B: Genes contain the code to manufacture proteins. Chromosomes don't manufacture genes.Why not C: Genes do use DNA to code for proteins, but not "for chromosomes." Chromosomes are basically the pieces of DNA that contain genes, which code for specific functions in the body and specific proteins.Answer:
D. chromosomes contain one or more genes.

Can someone please answer part A and B for me plz
Answer:
A. 25 miles per gallon
B. 225 miles
Step-by-step explanation:
Part A is asking for an average - how many miles does the car get out of each gallon. This can be found by dividing the total change in miles by the total change in gallons.
In this case, the changes in each are:
250 miles
10 gallons
250/10 is 25. Thus there are 25 miles per gallon.
Part B is asking for how much can you get with 9 gallons, meaning how many miles corresponds to 9 on the graph. The graph is at 225 miles at the x=9 mark, and thus the answer for part be is 225.

Write an algebraic expression for the number of hours in m minutes
Answer:
m/60.
Step-by-step explanation:
There are 60 minutes in an hour so the expression is m/60 hours..
The algebraic expression for the number of hours in m minutes is m/60. This is because there are 60 minutes in an hour, so dividing the number of minutes by 60 gives the equivalent number of hours.
Explanation:The task is to write an algebraic expression that represents the number of hours in m minutes. Since 1 hour is equal to 60 minutes, we can set up a conversion factor that allows us to go from minutes to hours. To find the number of hours in m minutes, we divide the number of minutes by 60 (the number of minutes in an hour). So, the algebraic expression for the number of hours in m minutes would be m/60.
To further simplify the context, think of a situation where you might need to convert 120 minutes to hours. Using the algebraic expression described, you would divide 120 by 60, which would result in 2. Therefore, 120 minutes is equal to 2 hours.

The pythagorean theorem
Answer:
In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.
