Answer:
-4/5
Step-by-step explanation:
Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.
The shortcut way to convert from a percentage to a decimal is by removing the percent sign and moving the decimal point 2 places to the left.
Answer:
32 meters long (please double-check! sometimes ppl make mistakes)
Step-by-step explanation:
the ratio of height to shadow length is 15:8, as established in the first sentence. if both sides of the ratio are multiplied by 4 then the ratio becomes 60:32.
more in depth:
if you think of it as fractions (which ratios can be written as) multiplying both the numerator and denominator by four is the equivalent of multiplying by 4/4 aka 1 so the value still stays the same (one times something is the same thing). since the ratio of height to shadow length is constant we needed to solve for the ratio in which the height is 60, so multiply each side by 4 (aka 60 divided by 15) to find the new ratio, 15(4):8(4) or 60:32. the ratio 60:32 describes height to shadow, so while the height is 60 (said in the problem) then the shadow length is 32. adding units, the answer would be 32 meters.
This is a case of use of multiplication operation.
This is, a train has 7 cars with 114 seat seat passengers, you could add up 114 seven times: 114 + 114 + 114 + 114 + 114 + 114 + 114, but instead you should use the multiplication which is a sum abreviated:
114
x 7

Answer: 798
The number rule for this sequence is that each time the number goes up,
it does so by whatever the previous amount added was, multiplied by two.
So far we can see the sequence is +50, +25-, +500, +1000, so we assume
that next it will be +2000 and the next number in the sequence will
therefore be 22,000
