Answer:

I'm here to answer.

I would say the correct answer is Most students have 2 or fewer siblings.

Step-by-step explanation:

There are only 1 students who has more than 4 siblings.

There are 12 students who has 2 or fewer siblings.

There are only 4 students who has 3 siblings.

There are only 2 students who has no siblings or 6 siblings.

The most number here is the second option, so the second option would be the correct answer.

PLEASE HELP :( I HATE SCHOOL

Answer:

100= 10+ 16t

Step-by-step explanation:

If beginning at 10 percent you initially are only in need for 90% charge. Earning 16% every thirty minutes you can initially do x4 for two hours on the charger and know you aren't at 100 yet. (16x4)+10= 64+10= 74. 100-74= 26. You need one more hour (total of 6 half hours) on the charger.

Another way of doing it could be 16÷90 and getting 5.blahblahblah and rounding up.

Part A

ira [324]

Answer:

Part A)

scientific notation ------> $2.56*10^{11}\ bits$

standard notation -----> $256,000,000,000\ bits$

Part B)

scientific notation ------> $5.12*10^{11}\ bits$

standard notation -----> $512,000,000,000\ bits$

Part C)

scientific notation ------> $1.28*10^{11}\ bits$

standard notation -----> $128,000,000,000\ bits$

Part D)

scientific notation ------> $6.4*10^{10}\ bits$

standard notation -----> $64,000,000,000\ bits$

Part E)

scientific notation ------> $3.2*10^{11}\ bits$

standard notation -----> $320,000,000,000\ bits$

Step-by-step explanation:

we know that

$1\ Gigabyte=1*10^{9}\ bytes$

$1\ byte=8\ bits$

therefore

$1\ Gigabyte=8*10^{9}\ bits$

Part A

Theresa and her brother, Ruben, are getting phones that each have 32 gigabytes of storage. How many bits of storage come with each phone? Type your answer in both scientific and standard notation

we know that

Each phone have 32 gigabytes of storage

using proportion

$\frac{1}{8*10^{9}}\frac{\ Gigabytes}{\ bits} =\frac{32}{x}\frac{\ Gigabytes}{\ bits}\\ \\x=32*8*10^{9}\\ \\x=256*10^{9}\ bits\\ \\x=2.56*10^{11}\ bits$

scientific notation ------> $2.56*10^{11}\ bits$

standard notation -----> $256,000,000,000\ bits$

Part B

Theresa’s parents, Cal and Julia, are getting phones that each have 64 gigabytes of storage. How many bits of storage come with each phone? Type your answer in both scientific and standard notation.

we know that

Each phone have 64 gigabytes of storage

using proportion

$\frac{1}{8*10^{9}}\frac{\ Gigabytes}{\ bits} =\frac{64}{x}\frac{\ Gigabytes}{\ bits}\\ \\x=64*8*10^{9}\\ \\x=512*10^{9}\ bits\\ \\x=5.12*10^{11}\ bits$

scientific notation ------> $5.12*10^{11}\ bits$

standard notation -----> $512,000,000,000\ bits$

Part C

Because they are getting four new phones, the family also gets two free tablets. Each tablet has 16 gigabytes of storage. How many bits of storage come with each tablet?

we know that

Each tablet have 16 gigabytes of storage

using proportion

$\frac{1}{8*10^{9}}\frac{\ Gigabytes}{\ bits} =\frac{16}{x}\frac{\ Gigabytes}{\ bits}\\ \\x=16*8*10^{9}\\ \\x=128*10^{9}\ bits\\ \\x=1.28*10^{11}\ bits$

scientific notation ------> $1.28*10^{11}\ bits$

standard notation -----> $128,000,000,000\ bits$

Part D

Theresa talked her parents into getting SD cards for her phone and her brother’s phone. Inserting an SD card into a phone gives it more storage. They both get 8-gigabyte SD cards. How many bits of storage come with each SD card? Type your answer in both scientific and standard notation

we know that

Each SD card have 8 gigabytes of storage

using proportion

$\frac{1}{8*10^{9}}\frac{\ Gigabytes}{\ bits} =\frac{8}{x}\frac{\ Gigabytes}{\ bits}\\ \\x=8*8*10^{9}\\ \\x=64*10^{9}\ bits\\ \\x=6.4*10^{10}\ bits$

scientific notation ------> $6.4*10^{10}\ bits$

standard notation -----> $64,000,000,000\ bits$

Part E

With their plan, the family also gets access to storage on the cloud. They can store a total of 40 gigabytes on the cloud. How many bits of storage do they get on the cloud? Type your answer in both scientific and standard notation

we know that

The cloud have 40 gigabytes of storage

using proportion

$\frac{1}{8*10^{9}}\frac{\ Gigabytes}{\ bits} =\frac{40}{x}\frac{\ Gigabytes}{\ bits}\\ \\x=40*8*10^{9}\\ \\x=320*10^{9}\ bits\\ \\x=3.2*10^{11}\ bits$

scientific notation ------> $3.2*10^{11}\ bits$

standard notation -----> $320,000,000,000\ bits$
