Answer:
Your answer would be 51.
Step-by-step explanation:
Remember the mathematical sequence: PEMDAS
P=parenthesis
E= exponents
M=multiply
D=divide
A=add
S=subtract.
In this case, there are no parenthesis and there are no exponents, so we multiply. Then there is no divide in this equation, so we go straight to add and subtract. Remember to do all this in the order of PEMDAS.
First, you multiply 0.7 and 60. 60 will be the minutes that equal one hour.
Finally, we can see that elephant can run up to 42 kilometers per hour. hope this helps!
Answer:
Heart sounds
Step-by-step explanation:
- Your doctor has allergic reaction, febrile rash, and meningitis in their differential for the patient.
- In a healthy adult, the heart makes two sounds, commonly described as 'lub' and 'dub. ' The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
We have q
consecutive integers in a set and q is odd.
If 120 is the middle number, then
there will be (q-1)/2 numbers
both before
and after 120.
Therefore, the largest number will
be (q-1)/2+120.

Calculate Jean's rate
----------------------------------------------
Jean takes 8 hours to fill the pool.
So in 1 hour, she can fill 1/8 of the pool
----------------------------------------------
Calculate Mark's rate
----------------------------------------------
Mark takes 12 hours to fill the pool.
So in 1 hour, he can fill 1/12 of the pool.
----------------------------------------------
Calculate their rate if they work together
----------------------------------------------
Jean = 1/8
Mark = 1/12
1/8 + 1/12 = 3/24 + 2/24 = 5/24
They will fill 5/24 of the pool in 1 hour
----------------------------------------------
Find number of hours needed to fill up the pool
----------------------------------------------
I hour = 5/24 of the pool
1 ÷ 5/24 hour = 5/24 ÷ 5/24 of the pool
24/5 hour = Whole pool
Whole pool = 24/5 hours
Whole pool = 4 4/5 hours or 4.8 hours
----------------------------------------------
Ans: The supervisor is not correct, it will take only 4.8 hours if both of them work together.
