Answer:
400% area and 200% perimeter
Step-by-step explanation:
Given is a picture of a rectangle. (i.e. opposite sides are equal and all angles equal to 90 degrees)
We know for any rectangle with length l and width, w
Area of rectangle = lw and
Perimeter of rectangle = 2(l+w)
Suppose the side lengths are doubled
Now length = 2l and width = 2w
New ARea =
i.e. 400% times is the new area.
New perimeter =
New perimeter is 200% times the old perimeter.
Answer:
f(-2) = 1
Step-by-step explanation:
f(-2) means find the y value when x = -2
Going to x=-2 and going up until we hit the blue line
f(-2) = 1
Y=mx+b
b is the y intercept.
b= -4 + or - 10.
Could go with 6 or -14.
Keep slope the same to have it parallel.
Equation could be y=3x+6 or y=3x-14.
Answer:4 to the power 15
Step-by-step explanation:
If one power is over the another power you need to multiply both of them..
So here the base is 4 and above it 3 and 5 will be multiplied3×5=15..so the answer is the 3rd one..
Here are 2 properties you must check..
Well if the alloy makes the 1000 grams, but you are dealing with copper that isn't even 100% copper, than you either need 55% more copper, which isn't given, which means you really need 550 grams of alloy copper.
