Answer:
83 m
Step-by-step explanation:
The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...
8.26(10 m) = 82.6 m ≈ 83 m
_____
The distance formula will tell you the distances are ...
AC = √(3² +1²) = √10
BD = √(5² +1²) = √26
The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.
Answer:
x=8 & x=6
Step-by-step explanation:
Answer:
We know that ,
Number of zeroes in a polynomial = degree of the polynomial
( degree of polynomial = the highest power in the polynomial )
therefore ,

Answer:
Step-by-step explanation:
The given inequality is
x+ (7 + 2x) <-3x
Expand parenthesis to get
x+ 7 + 2x <-3x
Group similar terms
x+ 2x +3x<-7
Combine similar terms
6x<-7
Divide both sides by 6
Rewrite as improper fraction
X= miles driven in April
(253 + 277 + 280 + x)/4= 284
add in parentheses
(810 + x)/4= 284
multiply both sides by 4
810 + x= 1136
subtract 810 from both sides
x= 326 miles
ANSWER: She must drive 326 miles in April to average at least 284 miles January through April.
Hope this helps! :)
