Answer:

$1.54 per pound

Step-by-step explanation:

The

3 \frac{2}{5}

pound bag of yarn costs $5.25.

To find the unit rate, we divide 5.25 by

3 \frac{2}{5}

\frac{5.25}{3 \frac{2}{5} }  = 1.54

To the nearest tenth,each pound costs $1.54 to the nearest cent.

This is what we call the unit rate. The rate per pound.

Answer:

B_2=4\pi r^2

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

B=\pi r^{2}

where

r is the radius of the circular base

If the radius is doubled

then

r=2r

The new base area is

B_2=\pi (2r)^{2}

B_2=4\pi r^2

so

B_2=4B

therefore

The new area of the base is 4 times the area of the original base

DENIUS [597]

Hi,

\frac{x^{a} }{x^{b} } =x^{a-b}

a)

\frac{x^{7} }{x^{3} }= x^{7-3} = x^{4}

b)

Maria works in a factory that produces new cars. She is having trouble with one of the machines. In order to work properly, the
Dovator [93]

Answer:

Maria did her job properly. Both gears are perpendicular.

Step-by-step explanation:

Recall that given vectors a and b, they are perpendicular if and only if a\cdot b =0. If a=(a_1,a_2),b=(b_1,b_2). Then a\cdot b = a_1b1_+a_2b_2.

IN our case a=(5,-1,2) and b) (1,-3,-4). So,

a\cdot b = 5\cdot 1 + (-1)\cdot(-3) + 2\cdot(-4) = 5+3-8 =0

So both gears are perpendicular.
