Answer:

2x + 1y =< 300

x + y =>150 units

y <= 2x

Step-by-step explanation:

Let x and y be the numbers of corndogs and shakes that will be sold.

<u>1.</u>  The total cost of making these items is given by the sum of:

(x)(RM2) + (y)(RM1)

A total of RM300 is allocated for the cost of these items, so:

2x + 1y =< 300   [Units are RM)

<u>2.</u> Sales are expected to exceed 150 units, in total.  This means:

x + y =>150 units

<u>3.</u>  Sales for the shakes is less than 2 times that of the corndogs:

y <= 2x

How many times can 200 go into 487
DedPeter [7]
2.435 times or if it’s to the nearest whole number then it can go into it twice. 200+200= 400. It can’t go in 3 times because that would be 600.

How does the volume of an oblique cone change if the height is reduced to 2/3 of its original size and the radius is doubled
spayn [35]

The volume of oblique cone =\frac{1}{3} \pi r^{2} h

Now radius is doubled is now it is 2r

And height is reduced to 2/3 of its original size that is 2/3 h

So plugging the values we get volume

New Volume = \frac{1}{3} \pi (2r)^2 (\frac{2}{3} h)

= \frac{1}{3} \pi 4r^2 (\frac{2}{3} h) = \frac{8}{6} \pi r^{2} h =\frac{8}{2} (\frac{1}{3} \pi r^{2} h )=4*(\frac{1}{3} \pi r^{2} h )

It means the volume becomes 4 times

Which equation does not represent a direct variation?
tatuchka [14]
Okay I think there has been a transcription issue here because it appears to me there are two answers. However I can spot where some brackets might be missing, bear with me on that.

A direct variation, a phrase I haven't heard before, sounds a lot like a direct proportion, something I am familiar with. A direct proportion satisfies two criteria:

The gradient of the function is constant s the independent variable (x) varies

The graph passes through the origin. That is to say when x = 0, y = 0.

Looking at these graphs, two can immediately be ruled out. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations.

This leaves B and C. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear.

This leaves C as the odd one out.

I hope this helps you :)

Geometry question, any help is appreciated
kodGreya [7K]

Answer:

Hence, the ratios are given by 5:7, 25:49, 125:343.

Step-by-step explanation:

We are given two spheres such that:

Volume of small sphere V_{s} = 250 yd^{3}

Volume of large sphere V_{l} = 686 yd^{3}.

Then the ratio of volume = 250 : 686 = 125 : 343.

Since, the volume of a sphere = \frac{4 \pi \times r^{3}}{3}, this gives us that the ratio of the radius = ∛V_{s} : ∛V_{l}

i.e. The ratio of the radius = ∛125 : ∛343 = 5 : 7.

Further, as the surface area of a sphere = 4 \pi \times r^{2}, this gives us that the ratioof surface area = r_{s} ^{2} : r_{l} ^{2}

i.e The ratio of the surface area = 5^{2} : 7^{2} = 25 : 49

So, the ratio of the surface areas = 25 : 49.

Hence, the ratios are given by 5:7, 25:49, 125:343.
