Answer:
Heyo. The answer is 60.48
Step-by-step explanation:
This is pretty easy, all you have to do is multiply the length, height, and width. Remember this. LxHxW. Thats is the formula. You do 4.2 cm, multiplied by 3.2 cm, then multiply that by 4.5 cm. Hope this helps! :)
Answer:
1
Step-by-step explanation:
Y=mx+b
so find your slope
y2-y1/x2-x1 so 13-7/4-2
you get 6/2 or simplified 3
so now you have the equation y=3x+b
next you want to plug in a point to your equation so
7=3(2)+b
now solve using PEMDAS
7=6+b
then you want to isolate your variable
7 = 6 + b
-6 -6
1=b and thats your slope intercept
hope this helped :)
Answer: length = 8cm; width = 6cm
Step-by-step explanation:
The dimensions of a rectangle are the length and width:
Let x be the length of rectangle, and
y, the width of rectangle
Perimeter equals 2x+2y=28, divide through by 2: x+y=14
Make y the subject, y=14-x, input the value of y into the equation and solve by pythagorean theorem:
x^2 + y^2= 10^2 = 100
x^2 + (14-x)^2 =100
x^2 +196-28x + x^2= 100
2x^2- 28x +196= 100
2x^2 -28x +96 =0
x^2 -14x + 48= 0
(x- 8) (x- 6)= 0
x= 8; or x = 6
The length of rectangle is 8 cm
The width of rectangle is 6 cm
I hope this helps.
Divide the top number by the bottom number, then move decimal point to the right two spots .
Answer:
m = -4
Step-by-step explanation:
First you have to deal with the right side of the equation since it's not spread out.
You therefore have to distribute (in order)
5×1= 5,
5×-m= -5m
And
-2×1 = -2
-2×-m = 2m
Now set it up in the order it was at first (not necessary, but helpful)
15 = 5-5m-2+2m
Add the common values...
5-2= 3
-5m+2m= -3m
Your equation should now look like this:
15= 3-3m
At this point you need to get the common values on the same side, so you would subtract 3 from both sides
15-3= 12
3-3= 0
Since you the 3 cancelled out on the right side, your equation now looks like this:
12= -3m
(Or -3m= 12)
At this point you only need to get m by itself so you would divide by -3 on both sides
-3m/-3= m (or 1m: m is understood as such)
12/-3= -4
The final answer should be
m = -4
