Answer:

0.7 square miles

Step-by-step explanation:

Square Kilometers and Square Miles are 2-D quantities.

When we normally convert one unit to another (such as km to mi), we have to multiply/divide ONCE. But when we are doing it with square quantities, we have to multiply/divide TWICE.

First, we need the conversion ratio (unit ratio). This is given as:

1 km = 0.6214 miles

Since we want to convert kilometers squared to miles squared, we have to multiply 1.8 (given) by 0.6214 TWICE. This is shown below (note that km^2 is canceled with mi*mi or mi^2):

1.8Km^2*\frac{0.6214Mi}{1Km}*\frac{0.6214Mi}{1Km}\\=1.8*0.6214*0.6214Mi^2\\=0.695Mi^2

So the answer is 0.695 square miles

Rounding to nearest tenth (1 digit after decimal), we get:

0.7 square miles

alexandr402 [8]

Answer:

6.7 /s.

Step-by-step explanation:

Initial velocity = u m/s

From the question, final velocity, v = - 2u m/s

Note - (the minus sign indicates that the direction was reversed and doubled)

t = 0.45

From equation of motion,

v = u + at

Acceleration, a = (v - u)/t

= (-2u - u)/0.45

= - 3u/0.45

Acceleration, a/Original speed, u = 3/0.45

= 6.7 /s

What is the solution to the system of equations?
MariettaO [177]

Answer:

x=-4 y=-1

Step-by-step explanation:

Let's solve your system by substitution.

−3x−8y=20;y=5x+19

Rewrite equations:

y=5x+19;−3x−8y=20

Step: Solve y=5x+19for y:

y=5x+19

Step: Substitute5x+19foryin−3x−8y=20:

−3x−8y=20

−3x−8(5x+19)=20

−43x−152=20(Simplify both sides of the equation)

−43x−152+152=20+152(Add 152 to both sides)

−43x=172

−43x

−43

=

172

−43

(Divide both sides by -43)

x=−4

Step: Substitute−4forxiny=5x+19:

y=5x+19

y=(5)(−4)+19

y=−1(Simplify both sides of the equation)

Answer:

x=−4 and y=−1
