Answer:

Yes

Step-by-step explanation:

The cost for each meal is 3.50 and there are five days so you would multiply 3.50 by 5 which equals 17.5. So it would cost the students 17.50 each week for the lunch, leaving them 2.50

Point A is on a number line halfway between −17−17 and 55. Point B is halfway between point A and 0. What integer does the point
julia-pushkina [17]
Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
         = 36

Now find B using midpoint formula:
B: (a+b)/2 
=36+0/2
=18

HELPP! Calculate S22 for the arithmetic sequence in which a12=2.4 and the common difference is d=3.4
Natalka [10]

Answer:

Option A is correct.

Value of S_{22} = 15.4

Step-by-step explanation:

Given: a_{12} = 2.4 and common difference(d) = 3.4

A sequence of numbers is arithmetic i.e,  it increases or decreases by a constant amount each term.

The sum of the nth term of a arithmetic sequence is given by;

S_n =\frac{n}{2}(2a+(n-1)d), where n is the number of terms, a is the first term and d is the common difference.

We also know the nth tern sequence formula which is given by ;

a_n = a+(n-1)d                             ......[2]

First find a.

it is given that a_{12} = 2.4

Put n =12 and d=3.4 in equation [2] we have;

a_{12} = a+(12-1)(3.4)

a_{12} = a+(11)(3.4)

2.4 = a + 37.4

Simplify:

a = - 35

Now, to calculate S_{22}

we use equation [1];

here, n =2 , a =-35 and d=3.4

S_{22} = \frac{22}{2}(2(-35)+(22-1)(3.4))

S_{22} = (11)(-70+21(3.4))

S_{22} = (11)(-70+71.4)

S_{22} = (11)(1.4)

Simplify:

S_{22} = 15.4

Therefore, the sum of sequence of 22nd term i.e, S_{22} = 15.4
