Answer:

32

Step-by-step explanation:

Let the number of girls in the class be 3. Then the number of girls who study German is , as is

the number of boys who study German. So the number of girls who study French is 2 and the

number of boys who study French is 2 × 2 = 4.

Therefore the total number of boys and girls in the class is + + 2 + 4 = 8 and hence is a

multiple of 8. Of the options, only 32 is divisible by 8.

Answer:

12.56m^2

Step-by-step explanation:

a = piR^2

The area of a sector of a given circle is 37.7 m².

Given that, the radius of a circle=4 m and the central angle of a circle=270°.

The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.

The formula to find the area of a sector is θ/360°(πr²).

Where r is the radius of the circle and θ is the angle of the sector.

Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².

Therefore, the area of a sector of a given circle is 37.7 m².

Answer:

(-4).(-4) = 4^2

Step-by-step explanation:

First, some rules that we need to remember:

if A is a positive number, then:

-A = (-1)*A

Also:

A*A = A^2

We also should remember that we can multiplicate in any order we want, this is:

A*B*C = (A*B)*C = A*(B*C)

And we also can change the order of the numbers:

A*B = B*A

And finally, we need to remember the sign rules for multiplication.

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Ok, now let's look at our expression.

(-4)*(-4)

First, we can rewrite this as:

( (-1)*4)*((-1)*4)

And we can rearrange the numbers to:

(-1)*(-1)*4*4

Now let's multiplicate the first two ones, because of the sign rule, we know that the outcome will be positive, and 1 times 1 is equal to 1,

(-1)*(-1) = 1

Then:

(-1)*(-1)*4*4 = 1*4*4 = 4*4

And we know that when a number is multiplied by itself we can rewrite it as:

4*4 = 4^2

Then:

(-4).(-4) = 4^2

The simplified expression is 4^2

Step-by-step explanation:

It costs . 31 cents for 1 pint of milk.

Answer:

1 pint would be ($1.25/4 pints) = $0.31

Step-by-step explanation:

There are eight pints in a US gallon, and thus four in half a gallon.

That comes to four pints of milk.

That's $1.24/(half gallon), or $2.48/gallon.

Since half a gallon (4 pints) is $1.25, 1 pint would be ($1.25/4 pints) = $0.31
