Answer:

-12.25

Step-by-step explanation:

Given the expression

1/4-20 x 5/8

To simplify, we will use PEMDAS rule

Solving the multiplication part

1/4-20 x 5/8

= 1/4 - (20*5/8)

= 1/4 - 100/8

Find the LCM

= 2-100/8

=  -98/8

= -12.25

Hence it has a length of -12.25

Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .
SOVA2 [1]

The general rule for the nth term of the sequence is a(n)=-6b+(n-1)(3b)

Explanation:

The sequence is -6b, -3b, 0b, 3b, 6b, .....

To find the nth term of the sequence, we need to find the common difference and the first term of the sequence.

First term of the sequence = -6b

Common difference = -3b-(-6b)=-3b+6b=3b

Using this the nth term of the sequence can be determined.

Since, this is an arithmetic sequence, the general form of AP is given by the formula,

a(n)=a+(n-1)d

where a denotes the first term of the sequence and d denotes the common difference. Thus, a=-6b and d=3b

Substituting the values in the general formula, we get,

a(n)=-6b+(n-1)(3b)

Thus, the general rule for the nth term of the sequence is a(n)=-6b+(n-1)(3b)

The Salami and More Deli sells a 5-foot submarine sandwich for parties. It weighs 8 pounds. Assuming that the weight per foot is
laiz [17]

Answer:

7.5 feet long

Step-by-step explanation:

if I had one, 5 foot sandwich, I would have 8 pounds. if I had 2.5 more foot of sandwich I would have 4 more pounds ( because 2.5 feet is half of 5 feet which means we would have to divide 8 pounds by 2). which means I have 8 pounds and 4 pounds, which equals 12 pounds. I also have 5 feet and 2.5 feet of sandwich which is equal to 7.5 feet. since it's asking the length of a 12 pound sandwich, your answer is 7.5 feet long.
