Answer:
Jill spent $14 dollars on 7 pencils
Step-by-step explanation:
Of the $24, she has $10 left, therefore, she spent $14 on the 7 pencils. You can tell now how much each pencil cost, since 7 goes into 14, 2 times. The answer is the cost for each pencil= $2.
For the first picture using Pythagorean Theorem, we know that a^2 + b ^2 = c^2 but since we only know c ( 99.2) and b ( 62 ) we need to use the theorem to find a the equation we use for that is :
A = square root of ( c^2 - B^2 )
A = 77.44

Answer: Choice A. </h3>
Explanation:
The notation or means to move any point (x,y) along the vector <-3,5>. Put another way, it says to shift (x,y) three units to the left and five units up. The x portion deals with left or right shifting, the y portion deals with up or down shifting. Since the x portion is negative, we go in the negative direction on the x axis. Y being positive means we move up rather than down.
This all means we end up with the translation rule
Farmer has 7 choice for cow out of which he choose only 2
4 choice for pig and he choose only 3 pigs
10 choice for sheep and he choose all 10 sheep
Number of ways of choosing cows = 7C2
Number of ways of choosing pigs = 4C3
number of ways of choosing sheep = 10C 10
all these three groups of different animals can make different groups when taken together
That is : 7C2 * 4C3 * 10C10 = 21 * 4 * 1 = 84 ways
Answer : 84
