Answer:
450,000,000mg
Step-by-step explanation:
1kg= 1000g
1g= 1000mg
Let's find out how many mg is 1 kg. In order to do so, multiply 1000 by 1000.
Therefore, 1kg= 1000(1000) mg = 1 000 000 mg
Now, let's solve the question by multiplying 1,000,000 by 450 since 450kg= 450(1 kg).
450kg= 450(1 000 000) mg = 450 000 000 mg
This is also equivalent to 4.50× 10^8 mg.

Answer:
m = 6 , n = 6
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values
cos30° = , sin30° = , then
cos30° = = = ( cross- multiply )
2m = 12 ( divide both sides by 2 )
m = 6
and
sin30° = = = ( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
Answer:
x=5
y=−1
Step-by-step explanation:
x+y=4
2x−5y=15
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
x+y=4,2x−5y=15
To make x and 2x equal, multiply all terms on each side of the first equation by 2 and all terms on each side of the second by 1.
2x+2y=2×4,2x−5y=15
Simplify.
2x+2y=8,2x−5y=15
Subtract 2x−5y=15 from 2x+2y=8 by subtracting like terms on each side of the equal sign.
2x−2x+2y+5y=8−15
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
2y+5y=8−15
Add 2y to 5y.
7y=8−15
Add 8 to −15.
7y=−7
Divide both sides by 7.
y=−1
Substitute −1 for y in 2x−5y=15. Because the resulting equation contains only one variable, you can solve for x directly.
2x−5(−1)=15
Multiply −5 times −1.
2x+5=15
Subtract 5 from both sides of the equation.
2x=10
Divide both sides by 2.
x=5
The system is now solved.
x=5,y=−1
Answer:
No
Step-by-step explanation:
600-248.9=351.1, which is how much yarn It's me Patrick has left.
351.1<354.03, so he doesn't have enough yarn left to make the second scarf.
