Since we can add a number to a tens number easily, we make one of the addends a tens number when solving an addition problem.
Example 1:
Add 9 and 6.
9 + 6 = 9 + (1 + 5)
= (9 + 1) + 5
= 10 + 5 = 15
Note that adding 10 and 5 is much easier than adding 9 and 6.
Example 2:
Add 18 and 16.
18 + 16 = 18 + (2 + 14)
= (18 + 2) + 14
= 20 + 14 = 34
Note that adding 20 and 14 is much easier than adding 18 and 16.
Answer:
Similar, SSS similarity, ΔLRS
Step-by-step explanation:
First, compare the ratios of the shortest sides:
LN / LS = 112 / 24 = 4⅔
And the longest sides:
LM / LR = 168 / 36 = 4⅔
And the middle:
MN / RS = 154 / 33 = 4⅔
The triangles' sides are proportional. Therefore, by SSS similarity, the triangles are similar.
Let P stand for the Paint crew...and you know that 75% of that crew = 105 people. So we know that...
P x .75 = 105
Divide both sides of the equation by .75 to solve for P...
P = 105/.75 = 140
So the total paint crew has 140 painters.
Answer:
<em>hello your question lacks some information attached below is the complete question</em>
answer : NO
Step-by-step explanation:
Determine the probability of not selecting an obese subject in 3 trials
= P ( not obese in 3 randomly selected ) = ( 1 - 0.111 )^3
= 0.703
The probability > 0.05
hence it is insignificant therefore the answer is NO
