Answer the question............
Answers
Hey there!
The answer to your first question is 4.5 inches by 6 inches.
We can solve this by doing 3 x 1.5 and 4 x 1.5, which equals 4.5 and 6.
The answer to the second part is 27 inches²
The formula for area is length times width, so you can do 4.5 x 6
The answer to the third part is Ralph is incorrect because he probably found the area of the original dimensions, and then multiplied it by 1.5. You have to find the actual dimensions first, and then find the area.
Hope this helps. Good luck, have a great day, and let me know if there's more.

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?
Answers
Answer:
7
Step-by-step explanation:
6,300 divide by 900 would equal 7
Answer:
7 beams
Step-by-step explanation:
To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:
6,300 ÷ 900 = 7
So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

f (x) = -x2 + 164x - 64, f(x) = -4x2 - 10x + 84, f(x) = 3x² + 24.
Answers
Answer:
You need to ask a question for someone to answer it.
Are you looking for their derivatives?
-x² + 164x - 64 => -2x + 164
-4x² - 10x + 84 => -4x - 10
3x² + 24 => 6x
Indefinite Integrals?
-x² + 164x - 64 => -x³/3 + 82x² - 64x + C
-4x² - 10x + 84 => -4x³/3 - 5x² + 84x + C
3x² + 24 => x³ + 24x + C
Want them factored?
-x² + 164x - 64 => has no factors
-4x² - 10x + 84 => 2(2x - 7)(x + 6)
3x² + 24 => 3(x² + 8)

what does the solution to the system c,p reprent in this situation 5c+4p=18.40
2c+4p=11.20
Answers
Answer:
4 and 4/15=c. 2 and 2/15=p.
Step-by-step explanation:
I am younger than 12 i dont have much experience; done 2 or 3 problems like this...
first lets make it simpler...
2c+4p=11.20 is the same as c+2p=5.6
then subtract one from the other and you get 4c+2p=12.8
simplify again 2c+p=6.4
so the ratio of c to p is 2:1. Multiply 6.4 by 2/3 to get what c is... 64/15
64/15 is 4 and 4/15. then divide by 2 to get what p is so 64/15÷2=32/15 which is 2 and 2/15.

Mathematically, this is;
I = PRT/100
P is the principal = $200
R is the rate = 5%
T is the time = 3 years
Substituting these values, we have;
I = (200 * 5 * 3)/100
I = $30

Slope: [tex]m=-\frac{1}{2}[/tex]
y-intercept: [tex](0,-1)[/tex]
Equation: [tex]y=-\frac{1}{2}x-1[/tex]
Step-by-step explanation:
Slope-intercept form of an equation is written as [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
The slope of a line that passes through the points [tex](x_1,\: y_1)[/tex] and [tex](x_2, \: y_2)[/tex] is [tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]. Using the coordinates [tex](-2, 0)[/tex] and [tex](2,-2)[/tex] as given in the problem, we have slope of this line to be:
[tex]m=\frac{-2-0}{2-(-2)}=\frac{-2}{4}=-\frac{1}{2}[/tex].
Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:
[tex]0=-\frac{1}{2}(-2)+b, \\ b=-1[/tex]
Therefore, the equation of this line in slope-intercept form is [tex]\fbox{$y=-\frac{1}{2}x-1$}[/tex].
The y-intercept occurs when [tex]x=0[/tex]:
[tex]y=-\frac{1}{2}(0)-1, \\\\y=1[/tex]
Thus, the y-intercept is
[tex](0, -1)[/tex]
