Answer:
=57.89%
Step-by-step explanation:
The total number of golf ball is 4+8+7 = 19
P (red or yellow) = number of red or yellow
------------------------------------
total number of golf balls
= 4+7
-----
19
=11/19
Changing this to a percent means changing it to a decimal and multiplying by 100%
= .578947368 * 100%
=57.8947368%
Rounding to two decimal places
=57.89%
Answer:
(a) Number of inches that have burned from the candle since it was lit is (1.1t) inches
(b) The remaining length of the candle is (16 - 1.1t) inches
Step-by-step explanation:
(a). Length of candle before it was lit = 16 inches
Constant rate at which at which candle burns = 1.1 inches per hour
Let t represent the number of hours that have elapsed since the candle was lit
In 1 hour, 1.1 inches of the candle burned
Therefore, in t hours, (1.1t) inches of the candle would have burned since the candle was lit
(b) Remaining length of candle = length of candle before it was lit - length of candle that have burned = 16 inches - 1.1t inches = (16 - 1.1t) inches
Answer: x = 2
Step-by-step explanation:
5x + 11 - 2x = 17
Combine like terms
3x + 11 = 17
Subtract 11 from each side
3x = 6
Divide each side by 3
x = 2
37.5 % of 800 is 300 because of division
This question is based on prime factorization method.
As given there are 12 peaches and 18 nectarines
Factors of 12 are : 2,3,4,6 and 12
Factors of 18 are : 2,3,6,9 and 18
As mentioned, fruits are divided into the same number of equal groups, so the groups can be formed as-
1. 6 groups of peaches with 2 in each and 6 groups of nectarines with 3 in each,
2. 3 groups of peaches with 4 in each and 3 groups of nectarines with 6 in each.
3. 2 groups of peaches with 6 in each and 2 groups of nectarines with 9 in each.
