If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?
pashok25 [27]
Inverse relationships are of the form xy=k or if you prefer  y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R

Krispy Kritters Cereal used to come in a
shtirl [24]

Answer:

1335cm³

Step-by-step explanation:

The question above says that,Krispy kritters cereal used to come in a box with a volume of 2,850 cm3. However, the krispy kritters co. Designed a new larger box 22.5 cm wide, 6.2 cm deep, and 30 cm high and we are now asked to find "How many more cubic centimeters will the new box hold than the old box?

Now we are all aware that the volume of a cube or cuboid(since its a box ) is length multipled by width multiplied by the height.

And we were given the new dimensions which are;

12.5cm wide

6.2cm deep and

30cm high

Apply this given figures in the formula above and we have:

V = 12.5 × 6.2 × 30

= 4185cm³( this is the volume of the box)

Therefore,the difference in volume between the new box and the old box is

4185 - 2850 = 1335cm³

1) 14 units2 2) 16 units2 3) 17 units2 4) 19 units2
horrorfan [7]

Answer:

<h2><em><u>4th</u></em><em><u> </u></em><em><u>option</u></em><em><u>:</u></em><em><u> </u></em><em><u>19</u></em><em><u> </u></em><em><u>units2</u></em><em><u> </u></em></h2>

Step-by-step explanation:

<h3>The given figure can be divided as (i) upper rectangle, (ii) lower rectangle </h3>

<em><u>Then</u></em><em><u>,</u></em>

(i) Breadth of upper rectangle = 2 units

Length of upper rectangle = 8 - 1 = 7 units

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the upper rectangle = 7 × 2 = 14 units2

(ii) Breadth of lower rectangle = 1 unit

Length of lower rectangle = 5 units

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the lower rectangle = 5 × 1 = 5 units2

<em><u>Since</u></em><em><u>,</u></em>

Area of the figure is = <em>Area</em><em> </em><em>of</em><em> </em><em>upper</em><em> </em><em>rectangle</em><em> </em><em>+</em><em> </em><em>Area</em><em> </em><em>of</em><em> </em><em>lower</em><em> </em><em>rectangle</em><em> </em>

= 14 units2 + 5 units2

= <em><u>19 units2 (Ans) (4th option)</u></em>
