A vendor bought 80 pineapples ₱18.50 each. Three pineapples got rotten, but then he sold the rest at ₱25.00 each. how much did he gain?
Answer:
₱445
Step-by-step explanation:
₱18.50(x)
x = number of pineapples purchased
₱18.50(80) = ₱1480
80 - 3 = 77
₱25.00(z)
z = number of pineapples resold.
25.00(77) = ₱1925
₱1925 = ₱1480 = ₱445

Answer:
2.15 × 10⁻³
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
y=2x−5 is a line
Step-by-step explanation:
Explanation: y=2x−3 is in slope intercept form for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. The y-intercept is the point at which x=0 and y=−3 , which is point (0,−3) You can plot this point on your graph.
solve the equation log2 x - 1/2 * log2 (x + 1) = 1
Answer:
0
Step-by-step explanation:
y is an irrational number between 3 and 4 . what is the value of y
Answer:
If a and b are two positive rational numbers such that ab is not a perfect square of a rational number, then ab is an irrational number lying between a and b.
So an irrational number between 3 and 4 is=3×4=3×4=3×2=23
What are the values of a and b, and what is an equation for the line?
Answer:
a = 1, b = 6
Step-by-step explanation:
slope of line = (5-2) / (12-3) = 3/9 = 1/3
(3-2) / (b-3) = 1/3
b-3 = 3 b = 6
(2-a) / (3-0) = 1/3
2-a = 1 a = 1

The y-intercept when in slope intercept form is the constant (the term with no x).
the perimeter of a square is 7.2 meters how long is each side ?
Answer:
1.8 meters
Step-by-step explanation:
7.2÷4= 1.8
Answer:
1.8 m
Step-by-step explanation:
let side be 'a'.
perimiter of a square = 4(a)
7.2 = 4(a)
7.2/4 = a
therefore, a = 1.8 m.

Which values from the set {0, 1/2 , 2.5, 4} make the inequality 8g < 4 true?
Answer:
only 0
Step-by-step explanation:
8g < 4 simplifies to g < 4/8, i.e., g < 1/2
only 0 is smaller than 1/2
Why is it important to be careful of the order of the two letters used when naming a ray?
Answer:
Because one letter represents an endpoint and the other doesn't.
Step-by-step explanation:
Ray AB starts at endpoint A and goes through point B and then on, indefinitely.
Ray BA starts at endpoint B and goes through point A and then on, indefinitely.
They 'point' in opposite directions.

Answer:
-4.75
Step-by-step explanation:
We're trying to find the number that's between -4 and -5. B is on -4.5, so we need to find a number between -4.5 and -5. This would be -4.75. Think of it like quarters, 4 quarters equal a dollar, and B would be the 2nd quarter (which is 50 cents). D would be the 3rd quarter (which is 75 cents). That's where the ".75" comes into the answer "-4.75". Just remember to put NEGATIVE 4.75 and NOT positive 4.75 since this is a negative number.
Hope this helped you!
