HELP! Will give Brainliest! Using dimensional analysis, convert 293 cm into m. (1 m= 100 cm)

1 answer:

6 0

To convert from one unit to another unit, a conversion factor is needed. This is a value that would relate the original unit to the desired unit. We either multiply or divide this value depending on what is being asked in the problem. For this problem, the conversion factor would be 1/100 which means that in 1 m there is 100 cm. We do the conversion as follows:

293 cm ( 1 m / 100 cm ) = 2.93 m

One number is 6 more than twice another. If their sum is 51, find the numbers.

joja [24]

Answer:

y=2x+6 ; x+y=51

Step-by-step explanation:

assuming x is one number and y is the other -

one number (y) is 6 more (+6) than twice another (2x) -

using that knowledge we form an equation -

y=2x+6

the sum (x+y) is 51

using this knowledge we can make the equation -

x+y=51

now you have -

y=2x+6 or 2x-y=-6

x+y=51

using system of equations -

you add the equations -

3x=45

x=15

y=51-x => y=36

hope this helps!!

What fraction is greater than 2/3

lutik1710 [3]

2/3 is basically 0.6666666667 which is the same as 66% so any percentage bigger than 66% such as 75% (0.75) which is 3/4 (as a fraction) is bigger than 2/3

What is the distance between points (9, −7) and (9, 4) on a coordinate plane? Enter the answer in the box.

katen-ka-za [31]

Answer:

$|d| = \sqrt{(9 - 9) {}^{2} + ( - 7 - 4) {}^{2} } = \sqrt{( - 11) {}^{2} } = \sqrt{121} = 11 \\$
