There are 15 students in total who like pineapple as a topping on their pizza.
In the question,
we are given that the total number of students are 95.
out of the total number of students we are given that 16% like pineapple as a topping for their pizza.
what is percentage?
The Percentage is a relative value that represents a quantity's hundredth parts. One percent (1%) stands for a hundredth, two percent (2%) for a two hundredth, 100% for the entire amount, 200% for twice that amount, and so on.
One percent of 1000 mangoes, for instance, is equivalent to 1/100 of 1000, or 10 mangoes.
now finding 16% of 95,
95 * 16/100
1520/100
15.20
rounding 15.20 off we get 15.
thus there are 15 students in total who like pineapple as a topping on their pizza.

Answer:
Step-by-step explanation:
From the question we are told that:
Table for price per Kg
Watermelon Rs 18.50
Cherry Rs 72
Grapes Rs 120.60
Apples Rs 78.40
Karan Bought:
412 kg watermelon
1 kg 200g cherries
250 g grapes
134 kg apples
Generally the equation for Total Price of Fruits Bought is mathematically given by
\sum (Price Rs* Weight kg )
Therefore the Amount of Money he gets back is
Therefore
He owes the shop keeper 2.74 million Rs
Answer:
-4
Step-by-step explanation:
- y = 3(x+5)²-4
- y= 3(x²+10x+25)-4
- y= 3x²+30x+75-4
- y= 3x²+30x+71
Derivate the function
solve the equation y'= 0
- y'= 6x+30
- 6x+30= 0
- 6x= -30
- x = -5
The extrme value of y is reached in -5
y = 3(-5+5)²-4= -4
Answer:
I. x = -1
II. y = 1
Step-by-step explanation:
Given the following algebraic expressions;
9x + 10y = 1 .......equation 1
9x - 6y = -15 ......equation 2
To solve using the elimination method, we would subtract eqn 1 from eqn 2.
(9x - 9x) + (-6y - 10y) = (-15 - 1)
0x - 16y = -16
-16y = -16
16y = 16
y = 16/16
y = 1
Next, we would find the value of x;
From eqn 1;
9x + 10y = 1
Substituting the value of y, we have;
9x + 10(1) = 1
9x + 10 = 1
9x = 1 - 10
9x = -9
x = -9/9
x = -1
