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.

The company has a sample box that is a rectangular prism with a rectangular base with an area of 231⁄3 in2. The height of the pr

vodka [1.7K]

Answer:

$29.17 in^3$

Step-by-step explanation:

We are given that

Base area of sample box,a= $23\frac{1}{3} in^2=\frac{70}{3}in^2$

Height of the sample box,h= $1\frac{1}{4}=\frac{5}{4} in$

We have to find the volume of the sample box.

We know that

Volume of rectangular prism, $V=ah$

Where a=Area of base

Using the formula

Volume of sample box= $\frac{70}{3}\times \frac{5}{4}=29.17 in^3$

Hence, the volume of the sample box= $29.17 in^3$

Yet another question.

inna [77]

Answer:

t= 3 years

Step-by-step explanation:

So far we have 2 useful relationships $P_{t}= P_{o} e^{r*t}$ and $P_{t}=2P_{0}$

Now, clearing t

$P_{t}= P_{o} e^{r*t} \\\frac{ P_{t}}{P_{o}} = e^{r*t}\\\frac{2 P_{0}}{P_{o}} = e^{r*t}\\2 = e^{r*t}$

I apply logarithm

$log(2)=r*t\\ t=\frac{log(2)}{r}\\t=\frac{0.3}{0.1} \\ t=3$ years

If represented in a stem and leaf plot, what would be the leaf of the number 329?

sdas [7]

Answer:

You can either do a back to back stem and leaf plot, where you would have double the values. In a normal stem and leaf plot you would just have one set of 3's where you would put all the values that start with 3 in that column. A back to back is the same but instead you would have two 3 values, where anything that is higher than 5 would be in the second value of 3, but anything lower would be in that first value of 3.
