Answer:
14 dollars
Step-by-step explanation:
To find the price, you multiply 3.50 with 400% or 4.00
3.50 x 4 = 14.00
multiply 5 and 2 then that with 23.
5x2=10 23x10=230
Answer:
128 ounces
Step-by-step explanation:
there are 16 ounces in each pound so 16 x 8 = 128 ounces
Answer:
$350
Step-by-step explanation:
If $280 is the 20% savings from the original price, it is 80% of original price.
280 / 0.8 = 350
From this equation, we can know that 350 is 100% of original price, which makes it the original price.
Hope this helps!
<span>The perimeter is 14.47
Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result.
Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5
Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5
Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47
Now add the length of each side together
5 + 5 + 4.47 = 14.47</span>
