Answer:

B. If A plant is bamboo, then it is a grass. If a plant is a grass, then it is a graminoid. A plant is bamboo. Therefore, the plant is a graminoid.

Step-by-step explanation:

A syllogism is a sequential implication:

If p then q, and If q then r ⇒ p therefore r.

To choose the example, you need to find the elements of each implication and see if they match this pattern.

A: p ⇒ q; q ⇒ r; r ∴ p . . . . not a syllogism

B: p ⇒ q; q ⇒ r; p ∴ r . . . . the syllogism we're looking for

C: p ⇒ q; q ∴ p . . . . not a syllogism

D: p ⇒ q; p ∴ q . . . . not a syllogism

Calculate S5 for the sequence defined by {an}={1+5/2n} 13.5 23 40 42.5

goldfiish [28.3K]

This is an arithmetic series, where S5 means the sum of the first 5 numbers in the series. The general formula is:

Sn = (n/2)(a1 + an)

So,
a1 = 1 + 5/2(1) = 3.5
a5 = 1 + 5/2(5) = 1.5

S5 = (5/2)(3.5+1.5)
S5 = 12.5

The answer should be 12.5

An artist used silver wire to make a square that has a perimeter of 40 inches. She then used copper wire to make the largest cir

Serhud [2]

Answer:

The artist used $8.6\ in$ more of silver wire

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

we know that

The Perimeter of the square is equal to

$P=4a$

where

a is the length side of the square

$P=40\ in$

$40=4a$

$a=10\ in$

Each side of the square has a length of 10 in

step 2

Find the circumference of the circle

The diameter of the circle is equal to the length of the side of the square

The circumference is equal to

$C=\pi D$

we have

$D=10\ in$

substitute

$C=(3.14)(10)=31.4\ in$

step 3

Find the difference

$40\ in-31.4\ in=8.6\ in$

Forth time I had to ask this!!

lubasha [3.4K]

A.) Yes you can, the expression would be (2.95 x Y) + 4 = X
B.) (2.95 x 24) + 4 = $74.80
C.) (2.95 x 57) + 4 = X
2.95 x 57 = 168.15 + 4 = 172.15
so basically they can buy 57 books without going over $175
