Answer:
About 19.8
Step-by-step explanation:
First find the side lengths. In this example, 56/4=14
Next use the Pythagorean theorem, to us it, here's the formula a squared plus b squared equals c squared. For this example use 14 squared plus 14 squared which equals 392.
Finally take the square root of 392 because we still need to take the squared out in c. The square root of 392 rounded to the nearest tenth is 19.8.
Answer: b. (2, 0)
<u>Step-by-step explanation:</u>
L = (-3, 3)
down 3 units means subtract 3 from the y-coordinate
new L = (-3, 0)
left 1 units means subtract 1 from the x-coordinate
newer L = (-4, 0)
reflection across x = -1 means measure the distance of the x-coordinate from x = -1 and move it to the other side that same distance. (-4 - (-1) = 3. --> -1 + 3 = 2
L' = (2, 0)
Answer: percentage of profit on the skirt is 11.1%
Step by step:
Let G denote price of gloves, and S the price of skirt, and let g dente the original cost of the gloves and s the cost of skirt. I will be using $ for the currency unit instead of the pound.
The sale equation is
$48 = G + S
100% profit on the gloves means:
G = 2 * g = 2 * $4
On the skirt, the profit is unknown ("x"):
S = x + s
We know that the total profit (total sale - total cost) after the sale is is 20%:
$48 - (s + $4) = 0.2 * (s + $4)
which finally gives us two equations with two unknowns:
$48 - (s + $4) = 0.2 * (s + $4)
$48 = 2 * $4 + x + s
which is straight-forward to solve. I got solutions as follows:
s = $36, x = $4
so the percentage of profit on the skirt is 100% * 4/36 = 11.1%
Answer:
x>-2
since the arrow goes to the right from -2 it is definitely greater than -2. now see that the line does not include the value -2 itself.. thus, we say it is greater than -2
0.1/0.4 converted to a decimal is 0.25 :) hope this helps
