Answer:

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days strech is 55.5miles.

Expression for the Total of Distance ran by MariaTotal distance = Distance ran each day × Number days

Given the data in the question;

- Distance ran each day by Maria Dm = 3.7miles

- Number days ran n = 15days

- Total number of distance ran by Maria TDm = ?

Total distance = Distance ran each day × Number days

TDm = Dm × n

We substitute in our values

TDm = 3.7miles × 15

TDm = 55.5miles

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days strech is 55.5miles.

Using the numbers 3, 2, and 4, which of these problems would have a solution of 4?

The correct answer is 4 * 2^3/2^3

what is BODMAS?BODMAS is an acronym for the sequence of operations to be performed while simplifying the mathematical expressions.

Given:

we have to solve the expression in such a way that it gives the answer 4.

so, for this we have

4 * 2^3/2^3

On solving it further

4*8/8

Using BOD MAS division will be performed first

=4

and, the other are

2 * 2^3/2^4

=1

3 * 2^3/2^4

=3/2

3 * 2^4/2^4

=3

Brian has reduced his cholesterol level by 7% after his last check up. If his original level was 240, what is his approximate cholesterol level now?

223.

7 x 240 = 1680.

1680/100= 16.8.

240-16.8 = 223.2. Round to nearest ten to get 223.

7 x 240 = 1680.

1680/100= 16.8.

240-16.8 = 223.2. Round to nearest ten to get 223.

Michael has 265 baseball cards. He wants to put them in packs of 9 cards each. How many cards will he have left over?

Michael will have 4 cards left because 265/9=29.4444444... then i do 29 (from the 29.4444) times 9 which gives me 261 and i did 265-261.

Jesse is building a spice rack. He cuts three lengths of wood from a 90-centimeter board. The first length is 23.5 centimeters. The second length is 33.3 centimeters. And the third length is 19.45 centimeters. How much of the original board remains after Jesse makes his cuts? A. 13.75 centimeters B. 76.25 centimeters C. 33.2 centimeters D. 3.75 centimeters

Since, Jesse is building a spice rack.

The total length of wood = 90 centimeters

He cuts the board into three parts.

The length of the first part = 23.5 cm

So, remaining length of the board = = 66.5 cm

Now, he cuts the second part.

The length of the second part = 33.3 cm

So, now remaining part of the board = = 33.2 cm

Now, he cuts the third part of the board.

The length of the third part = 19.45 cm

Now, the remaining part of the board = = 13.75 cm

So, the length of the original board after cutting the three parts = 13.75 cm

So, Option A is the correct answer.

Answer:

Step-by-step explanation:

So, the length of the original board after cutting the three parts = 13.75 cm

So, Option A is the correct answer.

A building is 2ft from a 7 ft fence that surrounds the property. A worker wants to wash a window in the building 11ft from the ground. He plans to place a ladder over the fence so it rests against the building. He decides he should place the ladder 7ft from the fence for stability. How long of a ladder will he need?

Answer:

The ladder is approx 14.21 feet long.

Step-by-step explanation:

The base of the ladder is 7 feet from the fence, which is 2 feet from the building, so it will be 9 feet from the building.

The top of the ladder will reach the window which is 11 feet from the ground.

In this way, we get a right triangle with the ladder as the hypotenuse, that we have to find.

Let the hypotenuse be x.

Using the Pythagorean Theorem, we get;

=>

=>

=>

=> x = 14.21

Hence, the ladder is approx 14.21 feet long.

Answer:

Step-by-step explanation:

plug the numbers into the Pythagorean theorem

which is A^2 + B^2 = C^2

A bicycle wheel of radius 42cm is rolled over a distance of 66m. How many revolutions does it make? [Take π=22/7]

In one revolution, the bicycle covers a distance equal to the circumference of the wheel.

So, in one revolution, the bicycle covers

In a distance of 66 m the bicycle makes revolutions

Answer: 25 revolutions

So, in one revolution, the bicycle covers

In a distance of 66 m the bicycle makes revolutions

Answer: 25 revolutions
