Answer:
when she sold 10 cards, it will cover all her cost.
Step-by-step explanation:
Profit(without charge of booth)=5x-2x
Profit=3x-30
Calculating:
3x=30
x=10
5 and three tenths translates to 5.3 and 2 and five tenths translates to 2.5... 5.3 - 2.5 = 2.8
2.8 translates to 2 and 8 tenths which can be simplified to...
2 and 4 fifths
Answer:
Option D: Absolute value function
Step-by-step explanation:
The absolute value of a number is the distance of the number from 0 to the left or right on the number line.
We are given the function;
f(x) = |2x³ - 3x| + 5
This function contains an absolute value symbol which is |2x³ - 3x|.
This function is thus illustrated by an an absolute value function because an absolute value function will be one that contains algebraic expressions within absolute value symbols.
Answer:
hi there!
there are three answers: x= 1.367, -1.367, and 0
Step-by-step explanation:
please refer to the graph down below
Since the ratio is 2:5, it could be written as a fraction: 2/5. To make this apply to the sides of the triangles you'd have to create an equation where 2/5 equals 5/x, x being the length of the hypotenuse.
2/5 = 5/x
To get from 2 to 5, you'd have to multiply 2 by 2.5. Therefore, in order to make the equation equal, you have to multiply 5 (the denominator of 2/5) by 2.5.
2/5 = 5/12.5
The hypotenuse would be 12.5 inches long.
