This year,a farm planted 400,000corn stalks.Last year,the farm planted 275,650cornstalks. How many more cornstalks did the farm

Bumek [7]

Answer:

The farm planted 124,350 more cornstalks

Step-by-step explanation:

Here in this question, we want to know how much more corn stalks did a farm plant this year compared to last year.

Let’s picture it this way;

Possibly due to expansion purposes, the farm planted more cornstalks this year than last year. So to find the difference in the cornstalks planter between the two years, what needs to be done is simply to subtract the number of corn stalks planted last year from the number of corn stalks planted this year.

From the question, the number of cornstalks planted last year was 275,650 while the number of cornstalks planted this year was 400,000; So the difference between the two will be ;

400,000 - 275,650 = 124,350 cornstalks

Morton made 36 out of 48 free throws last season. What percent of his free throws did Morton make. Help!!! T-T

blondinia [14]

75 % free throws are made by Morton

Solution:

Given that Morton made 36 out of 48 free throws last season

To find: Percent of free throws made by Morton

From given statement,

total number of throws = 48

throws made by morton = 36

Thus the percent of free throws made by Morton is given as:

$percent = \frac{\text{number of throws made}}{\text{total number of throws}} \times 100$

Substituting the values, we get

$percent = \frac{36}{48} \times 100\\\\percent = 0.75 \times 100 = 75 %$

Thus 75 % of his free throws are made by Morton

Which summation formula represents the series below? 13 + 9 + 5 + 1

Ket [755]

Answer:

The summation formula for the series is ⇒ 15n - 2n²

Step-by-step explanation:

* Lets check the series 13 , 9 , 5 , 1

∵ 9 - 13 = -4

∵ 5 - 9 = -4

∵ 1 - 5 = -4

∴ The series has a common difference

∴ It is an arithmetic series with first term a and constant difference d

* That means

- a1 = a , a2 = a + d , a3 = a + 2d , a4 = a + 3d

∴ an = a + (n - 1)d, where n is the position of the number in the series

* The sum of the arithmetic series can find by the rule

- Sn = n/2[2a + (n - 1)d], where n is the number of terms you want to add

* Lets use this rule in our problem

∵ Sn = n/2[2(13) + (n - 1)(-4)]

∴ Sn = n/2(26 + (-4n + 4)] ⇒ open the small bracket

∴ Sn = n/2[26 - 4n + 4] ⇒collect the like terms

∴ Sn = n/2[30 - 4n] ⇒ open the bracket

∴ Sn = (n/2)(30) - (n/2)(4n)

∴ Sn = 15n - 2n²

* The summation formula for the series is 15n - 2n²
