Answer:
5
Step-by-step explanation:
The height of the largest triangle = √(9 * 25) = 3 * 5 = 15
y is the square root of (25^2 + 15^2)
y = √(625 + 225)
y = √850
y = √(2 * 5*5 * 17)
y = 5 * √34
5 goes in the box.
For the question you want to:
For each book go across the graph how ever many pages there are and up how ever many words there are, then place a dot.
Answer:
1.56
Step-by-step explanation:
7 divided by 9 = .777777777
move the dot over 2 spots to the right = 77.78%
77.78% of 2 = 1.5556
round the nearest hundredth = 1.56
Answer:
$3000.
Step-by-step explanation:
Suppose the amount invested at 7% is $X and the amount invested at 10% is $Y (assuming that the college student invested all his/her income on the two schemes). Therefore:
X + Y = 8200 (The sum of investments is basically the total income).
0.07X + 0.1Y = 664 (The sum of the interest received from the invested amounts is actually the total return).
Now solving these 2 simultaneous equations:
x + y = 8200 (Equation 1)
7x + 10y = 66400 (Equation 2)
From (Equation 1):
x = 8200 - y (Equation 3)
Put (Equation 3) in (Equation 2):
7(8200 - y) + 10y = 66400.
57400 - 7y + 10y = 66400.
3y = 9000
y = 3000.
$Y is the amount invested at 10%, therefore the final answer is $3000!!!
