How many cubes that measure 2 inches by 2 inches by 2 inches would fit inside a cube that measures 10 inches by 10 inches by 10 inches? Justify.

Answers

25, because a cube that is 10x10 would have an area of 100. and the cubes that are 2x2 would have an area of 4. so you take 100 and divide it by 4. answer is 25.

The number of the small cube that fits inside the larger cube is 125.

Given to us,

Side of small cube, s = 2 inches,

Side of larger Cube. S = 10 inches,

We know that volume of a cube is given by , where "a" is the side of the cube.

Volume of the small cube = s³ = 2³ = 8 in.³

Volume of the Larger cube = S³ = 10³ = 1000 in.³

The number of the small cube that fits inside the larger cube

                                           [tex]\bold{=\dfrac{Volume\ of\ the\ Larger\ cube}{Volume\ of\ the\ small\ cube} }[/tex]

                                           [tex]\bold{=\dfrac{1000}{8} = 125 }[/tex]

Answer:

Step-by-step explanation:

Volume =  

  4 × π × r³ / 3    <----- This is our volume equation

= 4 × π × 1.9³ / 3    (Substituted the unknown r for the radius given, 1.9 cm)

= 4 × π × 6.859 / 3      (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9

= 4 × 21.548184011 / 3      (Multiplied 6.859 by pi "π")

= 86.1927360439 / 3         (Multiplied that by 4)

= 28.7309120146 cm³     (Divided it by 3, gave it a ³ dimension because it is 3D, volume.

Find the value for q for the following equation: 15q – 16 = 4(2q + 3)

Answers

Answer:
Q=4
15q-16=8q+12
7q-16=12
7q=28
Q=4
Step 1: Multiply 4 by 2q and 3

Now your equation is 15q - 16 = 8q + 12

Step 2: Subtract 8q from both sides

Now your equation is 7q - 16 = 12

Step 3: Add 16 to both sides

Now the equation is 7q = 28

Step 4: Divid each side by 7

Q= 4

Coupon A: 30% off of $63 shoes.

Coupon B: $22 rebate on $63 shoes.

Answers

Answer: Cupon B ($22 rebate on $63 shoes)

Step-by-step explanation: Cupon A would equal $44.10 while Cupon B would equal $41

The question you posted seems incomplete. You posted the set up information, but the actual question itself is missing. I'm assuming you want to find which is the better deal? If my assumption is correct, then go ahead and read on. If my assumption is incorrect, then you can ignore this post.

---------------

Solution:

The percent 30% converts to 0.30 when we move the decimal point two spots to the left. Note how 30% = 30/100 = 0.30

So saying 30% of 63 means 0.30*63 = 18.90, which is the amount of money we save. This value is smaller than the $22 rebate amount so that means Coupon B is the better deal.

We can see that if we go with Coupon A, then the final price will be 63-18.90 = 44.10; if we go for Coupon B, then the final sale price is 63-22 = 41. This is further confirmation that choice B is better.

Be careful though: The $22 rebate means that you'll have to mail (or possibly email) some kind of proof of purchase form/card. A bit of time will pass by until you can get the $22 in the mail. Some companies probably offer some kind of direct deposit. A rebate is basically a partial refund that acts more or less like a discount, but it's not an immediate discount. In short, you will not save the $22 right away and instead you'll be expected to pay the full $63 for the shoes when you're at the checkout counter. So if you want to save money right away, then go for option A. However, I still think option B is the better choice in the long run. Of course, it will depend on how long you're willing to wait for that savings.

Read the article "Overcoming Difficulties: How Helen Keller Learned to Communicate" and answer the question.Every day, millions of people worldwide use their mouths to speak, their ears to hear, and their eyes to see. However, not all people have those abilities. Some are born without the ability to speak, see, or hear. Others lose one or all of these abilities due to illness or accident. Not being able to communicate can be a major obstacle, but people who overcome these challenges are often determined, resourceful, and dedicated to helping others. Instead, people who have to overcome these challenges are often determined, resourceful, and dedicated to helping others.A Great TeacherOne person who did not allow her disability to limit her was Helen Keller. Keller, who became blind and deaf at the age of one and a half due to illness, learned at a very young age that her life was going to be different. As a child in the late 1800s, she did not have access to the technology we have today that assists people with disabilities in their daily lives. Instead, she had a very dedicated and creative teacher who stuck with Keller throughout her life. This teacher's name was Anne Sullivan. As a result of Sullivan's dedication and Keller's own determination, she learned when many thought she could not.Learning How to CommunicateSullivan helped her learn to communicate by using the resources and abilities Keller did have. Keller could touch, taste, and smell. Sullivan taught her to associate hand movements with words. She would spell words on Keller's hand while having her touch the related object. By associating a physical object with the hand movements, Helen learned the meaning of countless words. Learning to speak was tackled in a similar way. By feeling lips as they moved, Keller learned how to use her lips to form words. Using such innovative techniques and the resources available to her opened whole new worlds for Keller's learning. Sullivan encouraged and mentored Keller, never letting her give up and always believing the best for her.An Inspiration to OthersAnother way Keller learned to communicate was through writing. As an adult, she attended Radcliffe College, which allowed her to advance her education, even though many people doubted her ability to be successful. While she was there, she wrote her autobiography, which told the world about her struggles and accomplishments. She was able to share her story through Braille, a form of writing using raised dots felt with the fingers. Throughout her entire college career, Anne Sullivan was beside her, encouraging Keller and interpreting the words she could not see and the sounds she could not hear. Helen Keller's perseverance and Anne Sullivan's dedication became an inspiration for many children and adults around the world.Helen Keller went on to be a successful author and teacher. She became a mentor to other children and adults living with disabilities. To this day, Keller is remembered for her determination, resourcefulness, and dedication that helped her to overcome obstacles and inspire others.
