Mark spend 1 hour 10 minutes in reading.

<h3>What is Unitary Method?</h3>

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Mark spent 1 hour 17 minutes less than Sheila

Sheila spent 55 minutes less than Pete.

Pete spent 3 hours reading.

Since, pete spent 3 hours. So, Sheila spent

= 3 hours or (180 minutes) - 55 minutes

= 2 hours 05 minutes.

Now, Mark spent = 2 hrs 05 minutes - 55 minutes  

                            = 1 hour 10 minutes

A cube has an edge lengths of 5 cm. A rectangular prism has dimensions of 5 cm, 25 cm, and 1 cm. Which of the following statemen
murzikaleks [220]

The volume of cube and rectangular prism are same. Option B.

Step-by-step explanation:

Given,

The length of the edge of the cube (a) = 5 cm

The dimension of rectangular prism (l×b×h) = 5 cm×25 cm×1 cm

To find the relation between the volume of cube and rectangular prism.

Formula

The volume of a cube = a³ cube cm

The volume of rectangular prism = l×b×h cube cm

Now,

The volume of a cube = 5³ cube cm = 125 cube cm

The volume of rectangular prism = 5×25×1 cube cm = 125 cube cm

Hence,

The volume of cube and rectangular prism are same.

If you had a 15 foot ladder, how far away from the base of a wall would you have to put it to reach a window 12 feet up?
Kruka [31]

Answer:

9.000000001

Step-by-step explanation:

If the hypotenuse is  15, the ladder, facing the right angle, and the opposite is 12 we need to use SOH to find the angle.

sin of angle is opposite / hypotenuse

sin of angle is 12 / 15

12/15 = 0.8

sin^-1 of 0.8 = 53.13010235

Angle is that

Then we do this again but a different equation

cos of angle is adjacent (x which we are looking for) / hypotenuse

cos of 53.13... is x / 15

(15 x cos of 53.13... )is x

So 15 x cos of 53.13... is 9.000000001 feet away.

How do u find the mean median mode and range?
seropon [69]
Mean is the average. So you add up all the numbers and divide by how many numbers there were.

Mode is the number that occurred the most.

Median is the number that is in the middle when you list the numbers from least to greatest or greatest to least.

Range is calculated when you subtract the biggest number in the group by the smallest number.

Elena L [17]

Answer: 6

Step-by-step explanation:

You have been told to make 144 two ounce chocolate chip cookies so the total weight of those cookies is:

= 144 * 2

= 288 ounces

A pound is equivalent to 16 ounces.

The recipe yields 3 pounds of cookies which is:

= 3 * 16

= 48 ounces

For the recipe to make 288 ounces, you need to scale up by:

= 288 / 48

= 6
