The number is 6 because 14+6=20 and 6 is less than 14. Hope this helps.
Answer:
(a) 3 ft, 4 ft, 5 ft
Step-by-step explanation:
The triangle inequality requires the sum of the two short sides exceed the long side.
__
a) 3 ft + 4 ft = 7 ft > 5 ft . . . . . triangle is possible
b) 4 yd + 1 2/3 yd = 5 2/3 yd < 10 yd . . . . not a possible triangle
c) 3 ft + 3 ft = 6 ft < 7 ft . . . . not a possible triangle
d) 4 in + 4 in = 8 in . . . . not a possible triangle (not greater than 8 in)
__
The first set of side lengths can form a triangle: 3 ft, 4 ft, 5 ft.
Answer:
x = 34°
Step-by-step explanation:
To solve for 'x', we will need to use the Supplementary Angles theorem. This states that on a line, all angles must add up to 180°.
We can set up a simple algebraic equation to solve for 'x':
180 = x + 12 + 100 + x
180 = 112 + 2x **Combine like terms
68 = 2x **Divide both sides by '2'
x = 34°.
Therefore, the measure of ∠x = 34°.
Answer:
7 miles
Step-by-step explanation:
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered
Answer:
The total change in the amount of money in my account is $ 9.60
Step-by-step explanation:
Given:
Amount of money deposited each week, 
Amount of money withdrawn each week, 
∴ Amount of money deposited in 4 weeks, 
∴ Amount of money withdrawn in 2 weeks, 
Now, amount of money left in the account is the difference of the two amounts.
So, amount left = 
Therefore, the total change in the amount of money in my account is given as:
Total change = Initial amount after 4 weeks - Final amount in the account.
Total change = $ 50 - $40.4 = $ 9.6
