Is the expression 15 x 157 equivalent to<br> (15 x 15)??<br> ? Explain<br> Chann

Inessa05 [86]

Answer:

Step-by-step explanation:

15 x 15 would be way less that 15 x 157

15 x 15 is just 15 + 15 + 15..... 15 times

15 x 157 is 15 + 15 + 15..... 157 times

15 x 15 = 225

15 x 157 = 2355

Manuel has 18 yards of fabric to make table runners. It takes Three-fourths of a yard to make each runner. The expression that r

stira [4]

Inequality helps in comparison. The possible number of table runners that Manuel could make is 20, 22, and 24.

<h3>What is Inequality?</h3>

Inequality helps us to compare two unequal expressions to form an equation.

Given to us

Left over cloth = 18 - (3/4)t

In the given equation, t shows the number of table runners that can be made with 18 yards of fabric.

As the total amount of fabric that is used for making must not be more than 18 yards, we can write the equation as,

$\frac{3}{4}t \leq 18$

solving it for t,

$t \leq 18 \times \dfrac{4}{3}\\\\t \leq 24$

Thus, the number of tables runner that can be made with 18 yards of cloth such that the size of the table runner is $\frac{3}{4} t$ must be equal to less than 24.

Hence, the possible number of table runners that Manuel could make is 20, 22, and 24.

How are irrational numbers the result of adding rational numbers and irrational numbers or multiplying non zero rational numbers

mylen [45]

Rational numbers are numbers that can be expressed as a fraction (ratio). Irrational numbers can not be expressed like that (like sqrt(2)).

To prove your statement, assume the opposite until you have a contradiction.

If the result of adding them would be rational, then your irrational number can be expressed as the difference of two rational numbers, which itself is also a rational number. That cannot be, because it should be an irrational number. This contradiction forces that rational + irrational = irrational.

You can reason the same way for multiplication. Suppose rational * irrational = rational, you find that your irrational can be expressed as the fration of two rationals, which is a contradiction.
