Answer: 69
Step-by-step explanation: Percent multiplied by the total number of students: 8/100 x 75 = 600/100. (remember it is 8/100 because it’s 8%.)
Then you simplify which will then get you 6.
Afterwards you need to subtract those 6 students from the group of 75. 75-6=69. So, 69 students.
9×11+12×11+(2×0.5×9×12)+11×15=
=99+132+108+165=504cm²
Answer: There's a 3/10th chance its greater than 6.
Step-by-step explanation:
Donnell practiced for 7 hours while Marcus practices the piano for 4 hours.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of hours piano played by Donnell is D while by Marcus is M.
Then,
Since Donnell practiced the piano 3 hours longer than Marcus.
D = 3 + M ⇒ D - M = 3
And,
Together, Marcus and Donnelly practiced the piano for 11 hours.
D + M = 11
By adding
2D = 14
D = 7
And,
M = 11 - 7 = 4
Hence "Donnell practiced for 7 hours while Marcus practices the piano for 4 hours".

Which answer is right !
Leila used the distributive property in the first step to solve the given equation, multiplying both terms in the parentheses by the fraction 2/3.
In this step, Leila applied the distributive property. The distributive property states that a(b + c) = ab + ac. This property allows us to multiply a single term by two or more terms within a parenthesis. In this case, Leila multiplied the fraction 2/3 by both 'x' (the variable) and '5' (the constant), inside the parentheses.
So, the equation went from 2/3 (x + 5) to (2/3 * x) + (2/3 * 5), which follows the rule of distributive property ab + ac when applied to the given equation.
