4, Write an inequality to compare the numbers 7 1/8 v50

Anarel [89]

Answer:

see the explanation

Step-by-step explanation:

we know that

using a calculator

$7\frac{1}{8}=7+\frac{1}{8}= 7.125$

$\sqrt{50}= 7.071$

Compare the numbers

Seven an eighth is greater than the square root of fifty.

$7\frac{1}{8} > \sqrt{50}$

or

Square root of fifty is less than seven an eighth

$\sqrt{50}$

Help find missing segment??

AleksandrR [38]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Let x as the missing segment.

_________________________________

According to the Thales theorem :

$\frac{26}{x} = \frac{12}{36} \\$

$\frac{26}{x} = \frac{12}{12 \times 3} \\$

$\frac{26}{x} = \frac{1}{3} \\$

Inverse both sides

$\frac{x}{26} = \frac{3}{1} \\$

$\frac{x}{26} = 3 \\$

Multiply sides by 26

$26 \times \frac{x}{26} = 26 \times 3 \\$

$x = 26 \times 3$

$x = 78$

Thus the missing segment has a measure of 78 .

Consider the expression. What is the result of applying the quotient of powers rule to the expression?

fenix001 [56]

Answer:

Let us consider the expression:

$\frac{a^5\cdot b^6}{a^2\cdot b^9}$ (1)

Now, the quotient of power rules says that the numbers that have same base can be find by subtracting if powers are with same sign

And adding if powers are with opposite sign.

We will solve equation (1) by this quotient of power rule.

So, it can be rewritten as:

$a^{5-2}\cdot b^{6-9}$

$\Rightarrow a^{3}\cdot b^{-3}$ .
