There are 52 birds and acts in the store. For the same animals Kia counts 138 legs. How many birds and cats are in the pet store

KiRa [710]

Let's represent birds by the letter x and cats by the letter y. Since birds have 2 legs, and cats have 4, we can express this as:
$138 = 2x + 4y$
$52 = x+y$

We can solve by substitution. Let's solve for x in the second equation:
$x = 52-y$

Replace every x in the first equation by that:
$138 = 2(52-y)+4y$
$138 = 104-2y+4y$
$138 = 104 + 2y$
$34 = 2y$
$y = 17$

Now, plug that in for y in second equation and solve for x:
$52 = x + 17$
$x = 35$

Since x was the number of birds and y was the number of cats in the store, there are 35 birds and 17 cats in the store.

f the pattern in the table is extended to represent more equivalent ratios for 2:6, which pair of numbers would be in the column

olasank [31]

The pair of numbers that would be in the columns, considering the proportional relationship, is given as follows:

20 would be in the column for 2, and 60 would be in the column for 6.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a special linear function, with intercept having a value of zero, in which the output variable is obtained with the multiplication of the input variable and the constant of proportionality k, as shown as follows:

y = kx

The table is extended to represent more equivalent ratios for 2:6, hence the constant of the relationship is given as follows:

k = 6/2 = 3.

Hence the equation is:

y = 3x.

The values given by each column are given as follows:

Column 2: values of x.

Column 6: values of y.

When x = 20, the numeric value of the relationship is of:

y = 3 x 20 = 60.

Hence the first option is correct.

$\bf \sqrt{\cfrac{100}{144}}~~
\begin{cases}
100=10\cdot 10\\
\qquad 10^2\\
144=12\cdot 12\\
\qquad 12^2
\end{cases}\implies \sqrt{\cfrac{10^2}{12^2}}\implies \cfrac{10}{12}\implies \stackrel{simplified}{\cfrac{5}{6}}$

find the height of a cylinder whose volume is 41.5 cubic yards and has a radius of 2 yards. Please help

chubhunter [2.5K]

General formula :
V = pi x radius squared x height

41.5 = pi x 4 x h
41.5 = 4pi x h
41.5/4pi = h
3.302465069 = h
