Question 1: The measure of the radius is the height h of the parallelogram.
Answer: h = r = 9 cm
Question 2: The measure of the distance across the base is the beast approximate base of the parallelogram.
Answer: b = 28.5 cm
Question 3: Calculate 3 times the radius.
Answer: 3 x radius (r) = 3 x 9 = 27 cm
Question 4: What is the mathematical difference between b and 3r? Calculate the absolute value of the two values.
Answer: Ib - 3rI = 28.5 - 3(9) = 28.5 - 27 = 1.5 cm
Question 5: Calculate the area of the parallelogram.
Answer: A = 3r² = 3(9) = 3(81) = 243 cm²
Question 6: Calculate the area of the circle.
Answer: A = πr² = (3.14)(9)² = (3.14)(81) = 254.34 cm²
Answer:
81°
Step-by-step explanation:
Points A, B and C lie on the circle. A and C are endpoints, B is the vertex of the angle ABC. Angle ABC is inscribed angle subtended on the arc AC with measure 192°.
The measure of the inscribed angle subtended on the arc is half the measure of the central angle subtended on the same arc. The measure of the central angle is the same as the measure of the arc, so
Answer:
4n²+2n as a factorial is given as:
Step-by-step explanation:
We are given an expression which has to be converted into factorial form.
The expression is as follows:
Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.
Hence, multiplying and dividing by '(2n-1)!'; we get:
we know that x(x-1)(x-2)! = x!, so:
Answer:
The carpenter earned $176 for the week.
Step-by-step explanation:
Add up the hours worked: 3.25 hr + 7 1/4 hr + 5 2/4 hr
= 10 2/4 hr + 5 2/4 hr
= 16 hr
Now multiply this result by $11/hr:
($11/hr)(16 hr) = $176
So, 75% is the same as 3/4 right? The best way to do this would be to first find 1/4.
240/4 = 60
Now you know that 1/4 equals 60.
but.... you have 3/4
60 x 3 = 180
