Answer:
x - 31 
69
Tonisha has to make at least $100 in revenue
Step-by-step explanation:
Set up the inequality:
x - 31 represents her profit
Since she wants to make at least $69 a day, use 69
So, the inequality is x - 31 69
Then, solve for x to find how much she has to sell:
x - 31 69
x 100
So, Tonisha has to make at least $100 in revenue
Answer:
fun for kids and family fun
Step-by-step explanation:
A = bh/2
40 = x(2x)/2
80 = 2x²
40 = x²
x = sqrt40
x = +/- 2sqrt10
Measurement cannot be negative therefore x = 2sqrt10
Height = 2x = 2(2sqrt10) = 4sqrt10
The height of the triangle is 4sqrt10 cm or approximately 12.65cm.
Answer:
A
Step-by-step explanation:
The area of the large triangle is 36*24/2
minus the small triangle which is 21*14/2
so 432-147 = 285
