Mathematics

V125BC [204]3 years ago
4 0

Answer:

n and (n - 1) are consecutive integers.

Step-by-step explanation:

We are given 'n', a positive integer.

This 'n' can either be odd or even.

Case I:

When 'n' is odd

The n - 1 is even.

Note that the product of odd and even is always even. That is the product of n and (n - 1) is even.

Case II:

when 'n' is even

Then n - 1 is odd.

Again, using the similar logic we can say that the product of n and n - 1 should be even because here, 'n - 1' is even and 'n' is odd.

What is the greatest number of tables that can be made? Explain how did you decide on this number?
emmasim [6.3K]

The greatest number of tables that can be made is; 24 tables

<h3>Limiting Resources</h3>

To determine the limiting factor;

  • We must divide the number of all factors available by 72.

Hence, it goes that;

  • Only, 48/72= 0.66 balloons per chair
  • Only 24/72 = 0.33 flowers per chair
  • Only 32/72 = 0.44 candles per chair

However, it follows from the question that; the same number of centerpieces be used on each table.

Hence, the ratio of flowers per chair is lowest and hence, 72×0.33 flowers are used, 24 tables can therefore be set up.

1 QUESTION-30 POINTS<br> QUESTION PINNED BELOW
galina1969 [7]

Answer:

The scale is not reasonable.

Step-by-step explanation:

The painting is 48 inches  by 120 inches

The scale is 1 inch = 4 inches

Divide the painting size by 4

48/4 = 12 inches

120/4 = 30 inches

We would need paper that is

12 inches by 30 inches

Our paper is 12 inches by 24 inches

It is too small.  The scale is not reasonable

Which of the quadratic functions has the narrowest graph? y = –2x2 y=-1/2x^2 y = –4x2 y=1/7x^2
vovikov84 [41]
Look at the coefficient of x², ignore the positive or negative sign. The larger the coefficient, the narrower the graph. 
in this case, the coefficients are -2, -1/2, -4, and 1/7
ignore the positive or negative sign, 4 is the largest number, so y=-4x² is the narrowest.

Note: the positive/negative sign tells you whether the graph opens upward or downward. It doesn't determine the width of the graph.
