Answer:
20ft per minute
Step-by-step explanation:
Answer:
First question: 1.4
Second question: Option 3
Step-by-step explanation:
First question:
You simplify the left equation first,
-0.4 x -3.5 = 1.4 , -0.4 x 2.9 = -1.16
<u>1.4k - 1.16</u>
For this to equal the right equation, the number missing must be 1.4.
Second question:
You simplify the equation given to you first,
1/4 x 8 = 2 , 1/4 x 12 = 3
<u>2x + 3</u>
The option that is equivalent to the answer is option 3; 2x + 3
Answer:
1.50x + 2.25y ≤ 30
Step-by-step explanation:
Hi, let’s say that 'y' represent the tablecloths.
So, we have to write an inequality:
The product of the number of balloons (x) and the cost of each one (1.50) plus the product of the number of tablecloths (y) and the cost of each tablecloth (2.25) must be less or equal to Rosie's budget (30)
Mathematically speaking:
1.50x + 2.25y ≤ 30

Answer: The height of the tree is 12.57 ft.
Step-by-step explanation:
The height of a thing is proportional to the its shadow.
Let H = Height and S = length of shadow
Then by equation direct proportion , 
(i)
Given : A tree that casts a 22 ft shadow at the same time a 4 ft postpost casts a shadow which is 7-ft long.
Put 
in (i), we get
Hence, the height of the tree is 12.57 ft.
