Answer:
They are similar because Since all the sides are equal in each triangle, the ratio of corresponding sides will all be equal
Step-by-step explanation:
STV=STU+UTV
But,
STV=90° and STU = 75°
Therefore,
90=75+UTV => UTV = 90-75
Therefore, expression A is the one that can be used to find UTV.
Answer: X^4-3x^2=4
Step-by-step explanation:
X^4+8x^2+16-11x^2-44+24=0
X^4-3x^2-4=0
X^4-3x^2=4
Find the area of the wheel:
Area of a circle is found using the formula:
Area = PI x r^2
9 inch would be the diameter, so the radius would be 9/2 = 4.5 inches.
The area would be 3.14 x 4.5^2 = 63.6 square inches.
Now divide the price by the area to get price per square inch:
Cost per square inch = 18.60 / 63.6 = $0.29 (rounded to the nearest cent)
