Evaluate 1 whole number 2/5 + 3/4 and give your answer to one significant figure

ehidna [41]

Answer:

The answer is

<h3>2 to 1 significant figure</h3>

Step-by-step explanation:

$1 \frac{2}{5} + \frac{3}{4}$

To solve the question first convert the mixed fraction to an improper fraction

That's

$1 \frac{2}{5} = \frac{7}{5}$

So we have

$\frac{7}{5} + \frac{3}{4}$

Find the LCM of the fractions

The LCM of 5 and 4 is 20

That's

$\frac{7}{5} + \frac{3}{4} = \frac{7(4) + 3(5)}{20} = \frac{28 + 15}{20}$

$= \frac{43}{20}$

= 2.15

We have the final answer as

<h3>2 to 1 significant figure</h3>

Hope this helps you

Could somebody please help me with this?

For this problem, we are going to use the Remainder Theorem. This says that for $x - n$ to be a factor of a polynomial $p(x)$ , then $p(n) = 0$ . Essentially, it says that $x - n$ is a factor if when you substitute $n$ into the polynomial you get a result of 0.

Thus, in our case, when we substitute $x = 2$ into the polynomial, we should get an answer of 0 if $x - 2$ is a factor of the polynomial. Given this information, we can solve for $c$ :

$p(2) = 2^3 - 4(2^2) + 2c + 2 = 0$

$8 - 16 + 2c + 2 = 0$

$2c - 6 = 0$

$2c = 6$

$c = 3$

The solution is c = 3.

How do i know when a set of ordered pairs that represents a function?

pav-90 [236]

Answer:

How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

Almost done. I need help with this part

valentina_108 [34]

Answer:

$\%Percent = 14.3\%$

Step-by-step explanation:

Required

15 is what percentage of 105

To do this, simply divide 15 by 105 multiplied by 100%.

So, we have:

$\%Percent = \frac{15}{105} * 100\%$

$\%Percent = \frac{15*100}{105}\%$

$\%Percent = \frac{1500}{105}\%$

$\%Percent = 14.3\%$ --- approximated
