Answer:
- 3108
Step-by-step explanation:
The sum to n terms of an arithmetic series is
=
[ 2
+ (n - 1)d ]
Substitute the given values into the formula
=
[ (2 × - 26) + (23 × - 9) ]
= 12 ( - 52 - 207 )
= 12 × - 259 = - 3108
Answer:
(x ÷ 8) + 23 – 4 = 36
x = 136
Step-by-step explanation:
We meet again
so first divide 60 by 5
this gives 12
then multiply 12 by 4
giving a final answer of 48

Hello!</h2>
The answer is:
The fabric will cost $4.58
D.$4.58
<h2>Why?</h2>
Since it's a conversion exercise, we need to pay special attention to the conversion procedure.
From the statement we know that:

So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.
We have that:

Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:

Hence, we have that the cost of the fabric will be $4.58.
The correct option is: D.$4.58
Have a nice day!
(10*16)/2
160/2=80
The area is 80.
