Compare the values of the underlined digits. 3492 and 704. the underlined is 4

Answers

Answer:

Value of 4 in 3492 > Value of 4 in 704

Step-by-step explanation:

The given two numbers are 3492 and 704

Number Thousands Hundreds Tens Ones

3492 3 4 9 2

704 0 7 0 4

In 3492, 4 is at hundreds place and have a value of 4 × 100 = 400

In 704, 4 is at ones place and have a value of 4×1 = 4

Since 400 > 4

Value of 4 in 3492 > Value of 4 in 704

in 3,492 the 4 has the value of 400. In 704 the 4 has the value of 4 because is in the ones place

The perimeter of a rectangle is 36 inches. If the width of the rectangle is 6 inches, what is the length?A.30 inches
B.24 inches
C.18 inches
D.12 inches

Answers

$P=2(w+l)$
P - perimeter
w - width
l - length

$P=36 \ in \nw=6 \ in \n \n36=2(6+l) \n36=12+2l \n36-12=2l \n24=2l \nl=(24)/(2) \n l=12$

The answer is D. 12 inches.

P=36in, W=6in.

The width of the rectangle is 6 for one side and 12 total for both. So 36-12 is 24. That means the length total has to be 24 and that would be 12.

So the answer is D.12 inches.

If p+q+r = 1 and pq+qr+pr = -1, and pqr = -1, find the value of $p^(3)+ q^(3)+ r^(3)$

Answers

pq+qr+pr= pqr (because they are both equal to -1)
then you divide both sides by p to get
q+ qr/p + r = qr. then you divide both sides by q and get
r/p + r/q = r. so I divided both sides by r to get
P + q =0 therefore p= -q. putting that into the first equation allows you to get that r=1 because p and q cancel each other out. then I put that into pq+qr+pr=-1 so pq+q+p=-1 since p=-q the q+p gets canceled out and you're left with pq=-1 and since it is the product of the two numbers and q is the negative of p. q=-1 while p=1. therefore p=1 r=1 and q=-1
