Answer:
13.08
Step-by-step explanation:
Step 1: find the sum of all numbers
= 104.65
Step 2: divide by how many values there are
=8
Step 3: solve
104.65 ÷ 8 = 13.08125....
Step 4: round to the hundredths place
= about 13.08
<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
Answer:
a) #4 vertical angles are congruent
b) # 1 ∠3 ≅ ∠7
c) # 6 Transitive property
Step-by-step explanation:
a. Vertical angles - opposite angles that are equal.
b. corresponding angles - in the same place but on different parallel lines
and are equal.
c. a = b, b = c so a = c
17.94
Because 15% of $6 is .9 so
2.6x6.9=17.94
