As far as I can tell, is referring and assuming the ruler doesn't have any fractional values, namely it only has markings with integers.

so in short is asking, what are the two integers that the fractional 5¼ is between?

$\bf \boxed{5}\text{\textemdash\textemdash\textemdash}5\frac{1}{4}\text{\textemdash\textemdash\textemdash\textemdash\textemdash\textemdash\textemdash\textemdash\textemdash}\boxed{6}$

2, Ivan walks 4 miles in 80 minutes, How many miles can she walk in 345 minutes?

posledela

Answer:

17.5 milies

Step-by-step explanation:

80/4

=20/1

This means that Ivan can walk 1 mile in 20 minutes

To figure out how many miles Ivan can walk in 345 if she continues at that pace you divide 345 by 20

345/20 = 17.5

This means Ivan can walk 17.5 milies in 345 minutes

Find the missing length indicated.

kogti [31]

Answer:

Step-by-step explanation:

x is the geometric mean because it is a part of both the small triangle on the left (with base 81) and the whole triangle (with base 225). Setting up the geometric means formula:

$\frac{81}{x}=\frac{x}{225}$ and cross multiply to get

$x^2 =18225$ so

x = $\sqrt{18225}$ and

x = 135

Which equation is the inverse of 5 y + 4 = (x + 3) squared + one-half?

telo118 [61]

Answer:

The correct option is the last option d.) y = negative 3 plus-or-minus StartRoot 5 x + seven-halves EndRoot

Step-by-step explanation:

the given equation is $5y + 4 =(x+3)^{2} + \frac{1}{2}$

Therefore we can write $5y\hspace{0.1cm} = (x+3)^{2} + \frac{1}{2} - 4 \hspace{0.3cm} \Rightarrow \hspace{0.2cm} 5y = (x+3)^{2} - \frac{7}{2} \hspace{0.3cm} \Rightarrow \hspace{0.3cm} y = \frac{(x+3)^{2}}{5} - \frac{7}{10}$

To find the inverse of the above function let us replace x with y and y with x.

Therefore we get

$x = \frac{(y+3)^{2}}{5} - \frac{7}{10}$

Now we write the above equation with only y on the Left hand side and we will obtain the inverse of the given function

$y = \pm \sqrt{5 (x + \frac{7}{10} )} \hspace{0.1cm} - \hspace{0.1cm} 3 \hspace{0.1cm} \Rightarrow\hspace{0.1cm} y = \pm \sqrt{5x + \frac{7}{2} } - \hspace{0.1cm} 3 \hspace{0.1cm}$

Therefore the correct option is the last option d.) y = negative 3 plus-or-minus StartRoot 5 x + seven-halves EndRoot , $y = \pm \sqrt{5x + \frac{7}{2} } - \hspace{0.1cm} 3 \hspace{0.1cm}$
