A student has to be in one of those four ranks.
If a student is not a freshman or sophomore, he must be a junior or a senior.
All students make up 100% of the total number of students.
Since the freshmen are 35% of the students, and the sophomores are 30% of the students, then they make up 65% of all students.
100% - 65% = 35%.
That means the juniors and seniors combined account for 35% of all students.
A student selected randomly has a 35% probability of being a junior or a senior.
4 sweets cost 28p altogether
28÷4=7p for each sweet
If each sweet costs 7p, then 7 sweets would be multiplied by 7
7×7p=49p
7 sweets cost 49p
Answer:
2,3,5,6,9,10
Step-by-step explanation:
To do this, we can look at how each value divides into 90. If it produces a whole number, they will be consider to be divisible
This means 4 is the only value that is not divisible into 90
x = 30
Step-by-step explanation:
If you write out the equation, "The quotient of a number and five equals nine less than one half of the number." Then you get the equation:
First get rid of the denominator. Multiply by a least common multiple. (10) Then you have:
Get the variable on one side by subtracting 2x from both sides:
Add 90 to both sides:
Divide by 3 on both sides:
Answer: you got it right
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 35%, X is 140, so the equation is 35% * 140 = Y
Convert 35% to a decimal by removing the percent sign and dividing by 100: 35/100 = 0.35
Substitute 0.35 for 35% in the equation: 35% * 140 = Y becomes 0.35 * 140 = Y
Do the math: 0.35 * 140 = 49
Y = amount of discount= 49
So 35% of 140 is 49
140-49= sale price= 91
