Keeping in mind that there are 1000 grams in a KILOgram and that in 1 meter there are 100 cm, therefore in 1 m³, there are (100 cm)³, or 100³ cm³, then

\bf \cfrac{170~\underline{kg}}{\underline{m^3}}\cdot \cfrac{1000~g}{\underline{kg}}\cdot \cfrac{\underline{m^3}}{100^3~cm^3}\implies \cfrac{170\cdot 1000~g}{100^3~cm^3}\implies \cfrac{170\cdot 1000~g}{1000000~cm^3}
\\\\\\
\cfrac{170\cdot 1~g}{1000~cm^3}\implies \cfrac{170~g}{1000~cm^3}\implies \cfrac{17~g}{100~cm^3}\implies 0.17\frac{g}{cm^3}

A positive integer squared plus 3 times it’s consecutive integer is equal to 43
Eduardwww [97]

Answer:

the integer is 5

Step-by-step explanation:

x^2+3(x+1)=43

x^2+3x+3=43

x^2+3x+(9/4)=43-3+(9/4)

(x+(3/2))^2=42 1/4

x+(3/2)=sqrt(42 1/4)

x+(3/2)=6 1/2

x=(6 1/2)-(3/2)

x=5

check:

5^2+3(6)=43

25+18=43

43=43

When Tomas simplified the expression -2.6 + (-5.4), he got 2.8. what mistake did Tomas likely make?
vladimir2022 [97]

Tomas used incorrectly the rule of signs, the expression should be simplified as follows:

-2.6 + (-5.4)

-2.6 -5.4 = 8

<h3></h3><h3>What mistake did Tomas likely make?</h3>

Here Tomas wants to perform an addition between two numbers:

-2.6 + (-5.4)

And the outcome that Tomas gets is:

-2.6 + (-5.4) = 2.8

Here his mistake seems to bee that he thought the second number was a positive number, and he solved the operation:

-2.6 + 5.4

So, he used wrong the rule of signs.

Remember that the rule of signs says that:

(-)*(+) = (+)*(-) = (-)

Using that, we can rewrite the original expression:

-2.6 + (-5.4)

to:

-2.6 - 5.4

Solving that, we get:

-2.6 - 5.4 = -8

Which is the outcome that Tomas would have gotten if he had used correctly the rule of signs.
