Answer:
B
Step-by-step explanation:
SA/V = 300m^2/500m^3 -------- m^2 cancel out and so d othe 100
we get 3/(5m)
Sooo, I guess that's equal to 3/5 1/m and 1/m is m^-1 so we have (B)
Answer:dd and subtract the remaining numbers in the math problem. The sum will be the result of adding numbers, while the difference will be the result of subtracting them. For instance, in the math problem 4 + 3 - 5, the sum of 4 and 3 will be 7, and the difference between 7 and 5 will be 2.
Step-by-step explanation:
The linear function y = 3x is used to calculate the cost of 23 balloons as $69
<h3>Linear Function</h3>
A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,
- 'm' is the slope of the line
- 'b' is the y-intercept of the line
- 'x' is the independent variable
- 'y' (or f(x)) is the dependent variable
y = 3x
x = number of balloons
The cost of 1 balloon = $3
the cost of 23 balloon = x
x = 23 * 3
x = 69
The cost of 23 balloon is $69

Answer:
Option 2:
The variable a should be multiplied by Two-thirds only and then added to 10.
Step-by-step explanation:
Let the age be a
The sum of 10 and two-thirds of that tree’s age:
10 + ⅔a
is equal to 50:
10 + ⅔a = 50
⅔a = 40
a = 60
Perimeter is the distance around the outside.
A square has 4 equal sides:
Perimeter = 21 x 4 = 84 yards
