It took carlos 1 hour 53 minutes to mow the lawn if he started at 8;10 am what time did he finish

Answers

Answer 1
Answer: well lets start with the one hour part- 1 hour added on to 8:10 is 9:10 + 53min. is 10:03  so calls finished mowing the lawn at 10:03 am.
Answer 2
Answer: To find when Carlos finished, you need to add both times. You can add whatever you prefer first. Let's say you add 53 first. Break down 53 into 50 and 3. 810 + 50 = 860. In time measurements it would be 9:00. Now add the 3 to 9:00, which is 9:03. Now we can add an hour. 9:03 + 1:00 (1 hour) = 10:03.

So Carlos finished at 10:03 A.M. Make sure to label A.M, or it will most likely be incorrect.

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?"If J represents John's age, then which of the following equations could be used to solve the problem?

A. 3(J + 15) = J - 1
B. J + 15 = 3J - 1
C. J + 15 = 3(J - 1)

Answers

If J represents John's age, then J + 15 = 3(J - 1) equations could be used to solve the problem

What is Equation?

Two or more expressions with an equal sign is called as Equation.

Given that

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John.

F=Frank

J=John

S=Sue.

I am 15 years older than John

In the sense Frankes age is 15 more than John age, So it is 15+J

Sue is 1 year younger than John.

So Sue's age is less than john

J-1

"I am 3 times as old as Sue is"

Three times of J-1

3(J-1)

So equating this we get

Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.

15+J=3(J-1)

Hence 15+J=3(J-1) is the equation could be used to solve the problem.

#SPJ5

Frank = F

Sue = S

John = J

F=3*S

F = J+15

S = J-1

If you want to find Frank's age, then his age would be equivalent to John's plus 15 years.

A.-Would not work because Frank is three times Sue's age, not John's (left hand side of the equation).

B.-Notice that the right hand side of the equation is equivalent to Sue's age, which we know is John-1, however it is currently written to be "three times Sue's age minus one" which would give us John's age, plus two more years than his actual age on the left hand side.

C.-Frank's age is equal to John's plus fifteen (right side of the equation) and Frank is equal to Sue's age times 3. But, if Sue is in terms of Johns, then Sue's age is John's minus one. Therefore, Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.


Therefore C is the answer. C:

At a benefit concert, fourteen bands have volunteered to perform but there is only enough time for six of the bands to play. How many lineups are possible?

Answers

There are 2,162,160 possible combination that could be made if there are 14 bands and only 6 slots available. This is computed using factorial. By using factorial we first need to identify the number of band and the number of slots available. It could be express as 14! - 8! or 14 x 13 x 12 x 11 x 10 x 9, which is equal to 2,162,160 combination.

The volume of a cylinder is 36 pie cubic units and its height is 4 units. find its lateral area.

Answers

V=hpir^2
V=36pi
h=4
LA=2hpir
find r then find lateral area

36pi=4pir^2
divide by 4pi
9=r^2
sqrt both sides
3=r

LA=2hpir
LA=2*4*pi*3
LA=8*pi*3
LA=24pi

lateral area=24 pi squarea units

P = a + (n - 1)b, for b

Answers

P = a + (n - 1)b   Subtratc a from both sides
P - a = (n - 1)b   Divide both sides by (n - 1)
(P - a)/(n - 1) = b   Switch the sides to make it easier to read
b = (P - a)/(n - 1)
The answer is b=P-a-(n+1) all you had to do was the a and the parenthesis from the b and put it on the other side
