Answer:

<h2>There are 106 chairs in the hospital cafeteria.</h2>

Step-by-step explanation:

Givens

There are 20 tables.
65% of the tables have 6 chairs at each table.
35% of the tables have 4 chairs at each table.

The question is, what's the total number of chairs in the cafeteria?

We know by given that 100% represents 20 tables. We can use the rule of three, to find the number that represents a 65%, that is, if 100% is 20 tables, 65% how many tables would be?

$65\%\frac{20}{100\%} =13$

There are 13 tables of 6 chairs at each table.

Similarly, if 100% represents 20 tables, 35% how many tables would represent?

$35\%\frac{20}{100\%} =7$

There are 7 tables of 4 chairs at each table.

Then, we need to multiply to find the total number of chairs.

We know that there are 13 tables of 6 chairs, so

$13 tables \times 6 chairs=78 chairs$

We also know that there are 7 tables of 4 chairs, so

$7 tables \times 4chairs=28chairs$

Therefore, the total number of chairs is

$78+28=106$

There are 106 chairs in the hospital cafeteria.

Answer:

Step-by-step explanation:

So if their is 65% of 20 tables with 6 chairs that's 13 tables.

And if their is 35% of 20 tables with 4 chairs that's 7 tables.

40, 10, 5/2 5/8... (fractions) is it arithmetic or geometric and what are the next two terms PLZ HELP DUE IN 10 MINS

patriot [66]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the sequence

$40,\:10,\:\frac{5}{2},\:\frac{5}{8}$

A geometric sequence has a constant ratio 'r' and is defined by

$\:a_n=a_0\cdot r^{n-1}$

Computing the ratios of all the adjacent terms

$\frac{10}{40}=\frac{1}{4},\:\quad \frac{\frac{5}{2}}{10}=\frac{1}{4},\:\quad \frac{\frac{5}{8}}{\frac{5}{2}}=\frac{1}{4}$

The ratio of all the adjacent terms is the same and equal to

$r=\frac{1}{4}$

Thus, the given sequence is a geometric sequence.

As the first element of the sequence is

$a_1=40$

Therefore, the nth term is calculated as

$\:a_n=a_0\cdot r^{n-1}$

$a_n=40\left(\frac{1}{4}\right)^{n-1}$

Put n = 5 to find the next term

$a_5=40\left(\frac{1}{4}\right)^{5-1}$

$a_5=40\cdot \frac{1}{4^4}$

$a_5=\frac{40}{4^4}$

$=\frac{2^3\cdot \:5}{2^8}$

$a_5=\frac{5}{2^5}$

$a_5=\frac{5}{32}$

now, Put n = 6 to find the 6th term

$a_6=40\left(\frac{1}{4}\right)^{6-1}$

$a_6=40\cdot \frac{1}{4^5}$

$a_6=\frac{40}{4^5}$

$=\frac{2^3\cdot \:5}{2^{10}}$

$a_6=\frac{5}{2^7}$

$a_6=\frac{5}{128}$

Thus, the next two terms of the sequence 40, 10, 5/2, 5/8... is:

$a_5=\frac{5}{32}$

$a_6=\frac{5}{128}$

In French how would you conjugate verbs with "on"?

mafiozo [28]

You conjugate verbs with the pronoun 'on' the same way you conjugate verbs with pronouns 'il/elle'. "On" means "one", qs in "One can do x or y."

On a piece of paper, show how to find the slope between these two points: (-1,5) and (3,13). Show all of your work and simplify

dybincka [34]

Use the formula m = y2 - y1
————
x2 - x1
(-1 is x1, 5 is y1) (3 is x2, 13 is y2)
13 - 5 8
——— = — = 2
3 - (-1) 4

2 is the slope
