Answer:
15
Step-by-step explanation:
The formula for distance when given vertices is
√(x2 - x1)² + (y2- y1)²
Where we have points (x1,y1) and (x2,y2)
So, (-2,7) and (3, -3)
Distance = √(3 -(-2))² + (-3 -7)²
= √5² + (-10)²
= √25 + 100
= √125
= 15
Therefore, the distance between (-2,7) and (3, -3) is 15
Answer:
-8-(-11)-7
= -8+11-7
= 3-7
= -4
Step-by-step explanation:
Answer: 30% of decrease
Step-by-step explanation:
$13.95 - $10 = $3.95
$13.95___100%
$3.95___x= 28.31%
(3.95*100) / 13.95 = 28.31 = 30
Answer:
x=499.83
y=500.16
Step-by-step explanation:
We can solve this problem with a system of equations:
The total quantity of Nerds in the box:
(1)
The amount of Nerds left in the box:
The number of portions Mrs. Konings has taken:
The amount of Nerds left in the box decreases by a third each time she dumps out a portion:
(2)
Substituting (2) in (1):
(3) This is the equation
Let's find
:
(4)
Now let's find
by substituting (4) in (2):
(5)
