If cheese is $4.40 per kilogramme, what should I pay for 200 grammes?

Verizon [17]

1 kg is 1,000 grams.

200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.

Thus 200 g= 1/5 kg = 0.2 kg.

1 kg of cheese is $4.40,

so 0.2 kg of cheese is 0.2kg x $4.40/1kg=4.40 x 0.2 $= 0.88$

Answer: $0.88

Find the surface area of the composite figure

Gnoma [55]

Answer:

$=280$ $in^2$

Step-by-step explanation:

----------------------------------------

Let's find the surface area of the pink rectangular prism first.

$2*10=20+20=40$

$4*10=40+40=80$

$4*2=8+8=16$

$40+80+16=136$

The surface area for the pink rectangular prism is $136$ $in^2$ .

-------------------->>>>>

Now, let's find the surface area of the green rectangular prism.

$4*7=28+28=56$

$4*7=28+28=56$

$4*4=16+16=32$

$56+56+32=144$

The surface area for the green rectangular prism is 144 $in^2$ .

-------------------->>>>>

Now let's add the surface area of both rectangular prisms to find the surface area of the composite figure.

$136+144=$

$=280$ $in^2$

----------------------------------------

Hope this is helpful.

Please help me with this problem

Answer:

<em>The measures of angles A, B, and C are respectively 21°, 125°, and 34°</em>

Step-by-step explanation:

<u>Equations</u>

We are given some conditions applying to the internal angles on a triangle ABC.

The measure of angle A is 13 less than the measure of angle C.

The measure of angle B is 11 less than 4 times the measure of angle C

Let x = measure of angle C

The first conditions states:

$m\angle A = x-13$

The second conditions states:

$m\angle B = 4x-11$

The sum of all angles must be 180°, thus:

$x - 13 + 4x - 11 + x = 180$

Simplifying:

6x -24 = 180

Adding 24:

6x = 204

Dividing by 6:

x = 204/6

x = 34

$m\angle C = x = 34^\circ$

$m\angle B = 4x-11 = 4*34-11 = 125^\circ$

$m\angle A = x - 13 = 34 - 13 = 21^\circ$

The measures of angles A, B, and C are respectively 21°, 125°, and 34°
