I think thats right.
(length of tree's shadow)/(height of tree) = (length of person's shadow)/(person's height)
24/x = 8/5
24*5 = x*8
120 = 8x
8x = 120
8x/8 = 120/8
x = 15
The tree is 15 feet tall
Answer:
-12.8x - 20y + 8.4
Step-by-step explanation:
To do this you just multiply everything by negative 4
so we have 3.2x*-4 + 5y*-4 - 2.1*-4
This gives us
-12.8x - 20y + 8.4
The last term is positive because we multplied a negative by another negative
Hello!
2.x^2 - 1 = 2.3^2 - 1 = 2.9 - 1 = 18-1 = 17
Good luck!
The inequality to describe the situation is; 2a + 1b <= 18
Since according to the question;
- Tony has $18 to buy apples and bananas for a fruit salad.
- Apples cost $2 per pound and bananas cost $1 per pound.
- Let the number of apples bought be; a
- Let the number of bananas bought be; b
Therefore, the inequality to describe the situation is;
This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.
Additionally, Two possible combinations of pounds and apples that Tony can buy are;
- Tony buys 9 apples and no banana
- Tony buys 18 bananas and no apple.
