Time sensitive question. Find the sum of the first 26 terms of an arithmetic series whose first term is 7 and 26th term is 93.

lisabon 2012 [21]

ANSWER

$S_{26}=1300$

EXPLANATION

The sum of an arithmetic sequence whose first term and last terms are known is calculated using

$S_{n}= \frac{n}{2} (a + l)$

From the given information, the first term of the series is

$a = 7$

and the last term of the series is

$l = 93$

The sum of the first 26 terms is

$S_{26}= \frac{26}{2} (7 + 93)$

$S_{26}= 13 (100)$

$S_{26}=1300$

Please help! *Math (10 pts)*

Allisa [31]

It's linear

If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)

The formula for linear functions is y=mx +b

In this case b is 7

M=7-5/0+1

M=2

Now you just write the function down, it would be

F(x) =2x + 7

Amanda, Boris, and Jose sent a total of 124 text messages during the weekend. Amanda sent 8 fewer messages than Jose

GrogVix [38]

Answer:

Amanda= 14

Boris = 88

Jose= 22

Step-by-step explanation:

Amanda= jose-8

Boris = 4×jose

Jose= Jose

total all = 124

(jose-8)+(jose×4)+(jose)= 124

so we substitute jose with X .

(X-8)+(4X)+(X)=124

6X-8= 124.

6X=124+8

X=132/6

X= 22.

so that total jose is 22, minus 8 we get Amanda, times 4 we get Boris.

Jasmine can run in one hour is 7.25 miles.

<h3>What is the formula of unitary method?</h3>

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given that,

Jasmine can run 4 $\frac{5}{6}$ miles in $\frac{2}{3}$ of an hour.

$\frac{2}{3}$ of an hour = 4 $\frac{5}{6}$ miles

= $\frac{29}{6}$ miles

By using unitary method we will find the value of an hour.

1 hour = $\frac{\frac{29}{6} }{\frac{2}{3} }$

= $\frac{29}{6}$ × $\frac{3}{2}$

= $\frac{29}{4}$

1 hour = 7.25 miles

Hence, Jasmine can run in one hour is 7.25 miles.
