1) You have four tiles that say M, A, T, and H. How many words can you form from these tiles? For example, you can form "AMH" and "TH". (The words do not have to be valid English words.)
2)How many numbers among 1, 2, 3, 1000 are not divisible by 9?
3)Andrew chooses a number from 1 to 100, and Mary also chooses a number from 1 to 100. (They may choose the same number.) It turns out that the product of their numbers is even. In how many ways could Andrew and Mary have chosen their numbers?
4)How many numbers between 50 and 250 (inclusive) are not perfect squares?
5)Dmitri has a pair of standard dice; one die is blue, and the other die is yellow. He rolls both of his dice. How many ways could the number on the blue die be larger than the number on the yellow die?
6) Bob flips a penny, a nickel, and a dime. How many ways can she get at least two heads?
Answer:
3
Step-by-step explanation:
7.15 plus 9.95 = 17.1
so 60 divided by 17.1 = is 3.508
so you can buy 3 whole dresses.
First you would find how much 35 percent of 600 is using 600/100 to find the value of one percent. One percent equals 6 pounds.
The angle from which helicopter take off approximately equals 11.30993247;
Answer:
A: The chord is perpendicular to the diameter
Proof:
CE=DE (definition of bisector)
Center O, so OC and OD are radii.
OC=OD.
OE=OE.
OCE=ODE (SSS)
angle OEC = angle OED (corresponding parts)
angle OEC and angle OED are supplementary
So angle OEC and angle OED are both right angles.
CD is perpendicular to OE
CD is perpendicular to AB
