Bo has 144 stickers on a page. He gives 2/9 of the stickers to his sister. He gives 16 stickers to his friend. How many does Bo have left?
Answers
Answer:
127 7/9

polygon QRST has vertices Q41/2 , 2 R 8/2 ,2 S 8 1/2 , -3 1/2 and T 4 1/2,-3 1/2 is polygon qrst a reactangle? justify your anwerer
Answers
Answer:
QRST is a rectangle.
Step-by-step explanation:
To decide whether this is a rectangle or not, we have the following options to choose from:
Prove that:
2 pairs of sides are parallel and one angle is 90°
2 pairs of opposite sides are equal and one angle is 90°
1 pair of sides is parallel and equal and one angle is 90°
All four angles are 90°
The diagonals are equal and bisect each other. (same midpoint)
I will go with option 1, because this only requires finding the slope of each of the 4 lines.
Note that:
points Q and R have the same
y
value
⇔
horizontal line
points S and T have the same
y
value
⇔
horizontal line
points Q and T have the same
x
value
⇔
vertical line
points R and S have the same
x
value
⇔
vertical line
Therefore QRST has to be a rectangle because horizontal and vertical lines meet at 90°.
The opposite sides are therefore parallel and equal and the angles are 90°
The anwser is that a....

A basket contains 3 apples and 7 oranges. A fruit is drawn and put back into the basket. This process is repeated 3 times. What is the probability that selected three fruits are orange? **Please answer in fractions only!**
Answers
Answer:
the fraction of oranges in the basket would be 8/15 because we have 8 oranges and 15 fruits in total
Step-by-step explanation:
The probability for selection orange thrice from basket is 343/100.
What is the definition of the probability?Probability is synonymous with possibility. It is a mathematical branch that deals with incidence of a random event. The value ranges from zero to one. Probability has just been introduced in mathematics to predict the likelihood of events occurring.A basket contains 3 apples and 7 oranges.
Total fruits = 10.
A fruit is selected from the basket three times with replacement.
The probability for the selection of one orange is 7/10.
The probability for the selection of second orange is 7/10.
The probability for the selection of third orange is 7/10.
Thus, the probability for selection orange thrice is;
Probability (3 times orange) = 7/10×7/10×7/10
Probability (3 times orange) = 343/100
Thus, the probability for selection orange thrice from basket is 343/100.
