Brody sliced a small pizza into 12 equal pieces. He ate ~ of the pizza. Which model represents three-fourths of twelve?

EastWind [94]

Answer:

Pie chart.

9 slices

Step-by-step explanation:

Three-fourths of twelve is written as

3/4 * 12

i.e 3/4 is multiplied by 12

multiplying 3 by 12 gives 36 and dividing it by 4 gives 9 .

So Brody ate 9 slices out of the 12 slices of pizza.

The graph used in circular shape is called the a pie chart.

If we draw a pie chart 3 of the 4 sections will be colored showing that he ate 3/4 of the pizza representing 9 slices out of 12.

Each slice can be represented separately.

Adrian just got hired for a new job and will make $66,000 in his first year. Adrian was told that he can expect to get raises of

Ann [662]

Answer:

Adrian would make $196000 in his 26th year working.

Step-by-step explanation:

Adrian salary in first year = $66,000

As Adrian is expected to get raises of $5,000 every year going forward.

Here is the sequence of Adrian's raises:

5,000, 10000, 15000, 20000, 25000 .....

As the common difference between consecutive terms is constant.

d = 10000 - 5,000 = 5,000 ⇒ d = 15000 - 10000 = 5,000

So, Adrian's raises is in Arithmetic sequence.

a₁ = 5,000

n = 26

$\ a_{n}=a_{1}+(n-1)d$

Put n = 26 to get the total amount of salary raises in Adrian's 26th year.

$\ a_{26}=5000+(26-1)5000$

$\ a_{26}=5000+(25)5000$

$\ a_{26}=5000+125000$

$\ a_{26}=130000$

Total raises amount after 26th year = $130000

Adding total raises after 26th year to the initial salary would let us figure out the total salary Adrian would make in his 26th year.

So,

Total Salary after 26th year = initial salary + total raises of 26 years

= 66000 + 130000

= $196000

So, Adrian would make $196000 in his 26th year working.
