Answer:

$\boxed {\boxed {\sf A. \ 0.60 \ km}}$

Step-by-step explanation:

Distance (how far the submarine travelled) can be found by multiplying the speed by the time.

$d=s*t$

The speed is 2.4 kilometers per hour.

The time is 0.25 hours.

$s= 2.4 \ km/hr \\t= 0.25 \ hr$

Substitute the values into the formula.

$d= 2.4 \ km/hr * 0.25 \ hr$

Multiply. Note that the hours (hr) will cancel each other out.

$d= 0.6 \ km/hr *hr$

$d= 0.6 \ km$

The submarine travelled 0.6 kilometers in 0.25 hours.

A copy machine makes 44

andrew-mc [135]

44 per minute. 44 x 5 minutes = 220 copies. But you have have 30 seconds left, 30 is half a minute so you also split what the machine does in half which is 22. 220 +22= 242.
242 copies is my answer.

Which statements are true? (look at picture)

Makovka662 [10]

Answer:

D is true, E is true, F is true

Step-by-step explanation:

Hello,

n is an odd number it means that n = 2a+1 where a is integer

$n^2-1=(2a+1)^2-1=4a^2+4a+1-1=4a(a+1)$

this is not an odd number

$n(n-1)=(2a+1)2a$

this is not an odd number

$(n-1)^2=(2a+1-1)^2=4a^2$

this is not an odd number

$n^2+2=(2a+1)^2+2=4a^2+4a+1+2=4a^2+4a+3= 2(2a^2+2a+1)+1$

so this is an odd number

$n(n-2)=(2a+1)(2a-1)=4a^2-1=4a^2-2+1=2(2a^2-1)+1$

so this is an odd number

$(n-2)^2=(2a+1-2)^2=(2a-1)^2=4a^2-4a+1 = 2(2a^2-2a)+1$

this is an odd number

hope this helps

the area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?

Vsevolod [243]

Answer:

perimeters of the rectangle=p=46.014 metres

Step-by-step explanation:

Given that:

Length (l) = 21 m

Area of rectangle(A) = 42.15 meter-square

Width (w)=?

Required data:

Perimater of Rectangle=p=?

Calculation:

As we know that Area of rectangle=A=l*w

Putting the value we get

42.15 m(square)=(21 m)*w

or w=42.15/21

or w=2.007 m

Now to find perimters of rectangle we know that

p=2(l + w) metres

putting the values

p=2(21+2.007) metres

p=2(23.007) metres

p=46.014 metres
