Answer:
.45
Step-by-step explanation:
Para convertir 9/20 a decimal, simplemente divide 9 entre 20. No se preocupe. No necesita sacar la calculadora, porque lo hicimos por usted.
9/20 como decimal es: .45
Answer:
25%
Step-by-step explanation:
Its basic division really. The easiest way to think of it is how many times can 3 fit into 12 three fits into 12 four times in fraction that's 1/4 or 1 over 4. Just like the quarter (United States quarter) each one is 25 cents and you need 4 of then to make 1 US dollar or 100% so each group of three is 25 percent. This under standing could work with a variety of numbers 5 is what percent of 20 or 7 is what percent of 28 if it comes in 4s each is 25%. Hope this helps.
x + 9 = -44
1. Subtract 9 to both sides
x = -53
9514 1404 393
Answer:
warmer by 30.2 degrees
Step-by-step explanation:
It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).
The difference can be found by subtracting the colder temperature from the warmer one:
-32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees
The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
Slope is calculated as the change in y over the change in x, or rise over run.
The change in y is the difference between the two given y-coordinates: 4 - (-3) = 7
The change in x is the difference between the two given x-coordinates (note that the order of the difference must be the same as the order of the difference of the y values): 1 - 1 = 0
So, 7/0 is the slope, but you cannot divide by 0, so the slope is undefined.
