Answer:
31.25
Step-by-step explanation:
25 is 80% of the original. Divide 25 by 8 to get 10%. This is 3.125. Multiply this by 10 to get 100%, and therefore the full amount.
Answer:
M'(2,4), P'(2,5), A'(4,5), T'(4,4)
Step-by-step explanation:
The translation 1 unit to the right and 2 units up has the rule
(x,y)→(x+1,y+2)
Rectangle MPAT has vertices at points M(1,2), P(1,3), A(3,3) and T(3,2). The image rectangle is rectangle M'P'A'T'. According to translation rule:
- M(1,2)→M'(2,4);
- P(1,3)→P'(2,5);
- A(3,3)→A'(4,5);
- T(3,2)→T'(4,4).
Answer: For 5 pirate ships, you need 55 pirates. For 11 pirate ships, you need 121 pirates.
Step-by-step explanation:
22 (# of pirates) divided by 2 (# of ships) = 11 pirates per ship. Use this knowledge of 11 pirates per ship to find how many pirates you need for different numbers of ships:
11*5= 55 for 5 ships &
11*11= 121 pirates for 11 ships.
Answer:
(15x - 4) (x + 2)
Step-by-step explanation:
Since the 15x is squared, the first group is going to have a 15x as its first number and the second group will have x as its first number (15x * x = 15x^2)
This will give you:
(15x ) (x )
Next, fill in the blanks by finding a number that multpilies to -8 (the last number of the expression) and adds to -2 (the second coefficient of the expression). If you think about it and try different numbers, you'll eventually find that -4 and 2 multipy to make -8 and add to make -2.
I hope this helps, good luck on the rest of your homework.
