What is 27kg+ 547g+ 694g equal to?

Mathematics

First, you have to convert 27kg to g. which equals 27000.
after that, you add 27000+547=27547
last, you add the 649 to 27547.
27547
+ 694
28241g
if you still have to convert it to kg, you would move the decimal over 3 times
28.241kg

Its 28214 grams. There are 1000 kilograms in a gram so you do 27 x 1000=27000g
Then you add 27000+547+694= 28214

Isolate I for the literal equation V = IR
Anit [1.1K]

In order to isolate any term from an equation we need to clear out any different variable or numbers different from the one we want

V=IR

in this case I is being multiplied by R, so we need to do the opposite which is divide in order to eliminate

V=\frac{IR}{R}

But since this is an equality we must do it on both sides so de equation does not get altered

\frac{V}{R}=\frac{IR}{R}

Then we simplify the equation

I=\frac{V}{R}

Sandra throws an object straight up into the air with initial velocity of 38 ft per square from platform that is 30 ft above the
expeople1 [14]

Answer:

3 seconds.

Step-by-step explanation:

We have been given that Sandra throws an object straight up into the air with initial velocity of 38 ft per second from platform that is 30 ft above the ground.

To find the time it will take for object to hit the ground, we will use formula:  

h(t)=-16t^2+v_0t+h_0, where, v_0 represents initial velocity and h_0 represents initial height.

Upon substituting our given initial velocity and initial height, we will get:

h(t)=-16t^2+38t+30

We know that object will hit the ground, when height will be 0, so we will equate object's height equal to 0 and solve for t as:

-16t^2+38t+30=0

Divide by 2:

-8t^2+19t+15=0

Upon using quadratic formula, we will get:

t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-19\pm\sqrt{19^2-4(-8)(15)}}{2(-8)}

t=\frac{-19\pm\sqrt{361+480}}{-16}=\frac{-19\pm\sqrt{841}}{-16}

t=\frac{-19\pm29}{-16}

t=\frac{-19-29}{-16},t=\frac{-19+29}{-16}

t=\frac{-48}{-16},t=\frac{10}{-16}

t=3,t=-\frac{5}{8}

Since time cannot be negative, therefore, it will take 3 seconds for object to hit the ground.

-32x + 45 – 7 (2x – 9) = 101
Evgesh-ka [11]

Answer:

x =  \frac{7}{46}

Step-by-step explanation:

-32x+45-7(2x-9)=101

parenthesis first

-32x+45-14x+63=101

just combine like terms

-46x+108=101

minus 108 both sides

-46x= -7

answer is x 7 over 46
