40+40x0+1=
What is the correct answer?
The correct answer will be 41.
A mathematical term is given ; 40 + 40 × 0 + 1
What will be the correct answer ?
What is the PEMDAS rule ?
PEMDAS rule follows the order which is parentheses, exponents, multiplication, division, addition, subtraction.
The given mathematical term is ;
= 40 + 40 × 0 + 1
We need to solve the given mathematical term according to the PEMDAS rule . Here , we firstly need to multiply 40 with 0 and then add rest of the values.
⇒ 40 + 40 × 0 + 1
firstly solve , 40 × 0 ;
= 40 + 0 + 1
then addall terms ;
= 41
Thus , the correct answer will be 41.

To find the rate at which the lawn sprinkler would fill the pool if used alone, subtract the rate of the hose from the combined rate. The equation is rs = 1/5 - 1/8.
To determine the rate at which the lawn sprinkler would fill the pool if used alone, we can set up an equation using the concept of rates. Let r be the rate at which the sprinkler fills the pool. If it takes 8 minutes for Byron to fill the pool with just the hose, then the rate of the hose alone is 1 pool/8 minutes, or rh = 1/8. If it takes 5 minutes to fill the pool when both the hose and sprinkler are used together, then the combined rate is 1 pool/5 minutes, or rc = 1/5.
The rate of the sprinkler alone, rs, can be determined by subtracting the rate of the hose from the combined rate. Thus, we have rs = rc - rh. Substituting the given values, we have rs = 1/5 - 1/8.
Therefore, the equation that can be used to determine the rate at which the lawn sprinkler would fill the pool if used alone is rs = 1/5 - 1/8.

Answer:
Step-by-step explanation:
The formula for simple interest is prt = I, where p is the initial investment (our unknown in this case), r is the interest rate in decimal form, t is the time in years, and I is the interest earned. That is NOT the same as the amount of money in the account t years later.
For us,
p = ??,
r = .05,
t = 18, and
I = 225.
Filling in:
p(.05)(18) = 225 and
.9p = 225 so
p = 250
Answer:
The answer is $250.
Step-by-step explanation:
First, the money that his grandmother deposited is called the principal, P. Substitute the given values into the formula, interest equals principal times rate times time, and solve for P. Here, I is 225 dollars and t is 18 years.
Next, the percent given represents the interest rate, r, but first it must be changed to a decimal. To change it, move the decimal point 2 places to the left.
Now, multiply point 0, 5, and 18 to simplify the right side of the equation. The product is point nine.
Finally, divide both sides of the equation by .9 . The result is P equals $225 The principal, or original deposit, is $250.
