Answer:
25.1 inches
Step-by-step explanation:
Radius of the circle = 4 inches
We have to calculate the value of Circumference of the circle.
The formula to calculate the circumference is:
Circumference = 2πr
We have to use π = 3.14, as said in the question:
So using the values, we get:
Circumference = 2 x 3.14 x 4 = 25.12 inches
Number of decimals in radius is zero, so we have to round the answer to one decimal place as said in the question.
Therefore, the circumference of the circle rounded to one decimal place will be 25.1 inches
Answer:
The number of cats are 23 and the number of dogs are 10 at the shelter on tuesday .
Step-by-step explanation:
Let us assume that the number of cats be x .
Let us assume that the number of dogs be y .
As given
An animal shelter spends $1.50 per day to care for each cat and $8.50 per day to care for each dog.
Levi noticed that the shelter spent $119.50 caring for cats and dogs on Tuesday.
Equation becomes
1.50x + 8.50y = 119.50
Simplify the above
150x + 850y = 11950
Levi found a record showing that there were a total of 33 cats and dogs on Tuesday.
Equation becomes
x + y = 33
Two equations are
150x + 850y = 11950
x + y = 33
Multiply x + y = 33 by 150 and subtracted from 150x + 850y = 11950 .
150x - 150x + 850y - 150y = 11950 - 4950
700y = 7000
y = 10
Putting value of y in the equation x + y = 33 .
x + 10 = 33
x = 33 - 10
x = 23
Therefore the number of cats are 23 and the number of dogs are 10 at the shelter on tuesday .
