Answer:
Base=8.4 inches
Step-by-step explanation:
Area of triangular bandana is 38sq inches
Height of triangle is 9 inches
Area of ∆ =½×b×h
38=½×b×9
38×2=b×9
76/9=b
b=8.4 inches
Answer:
8 = 4 +$
Step-by-step explanation:
A) You need to answer both parts. Yes, Elliot's fee increases by $60 per year. The initial value of Elliot's fee is $750.
B) The answers to part A give you all the information you need to write a suitable equation in slope-intercept form. The slope is the rate of change per year (60), and the intercept is the initial value (750).
.. fee = 60*(years since 2000) +750 . . . . . fee is in dollars
If you like, you can define and use single-letter variables for "fee" and "years since 2000".
____
Be careful with hyphens and minus signs around numbers. The way you have written your answer makes it look like the rate of change is -60. Oops.
Diameter = 30
30/2 = 15 15 is the radius
To find area:
3.14 x 15 x 15 = 706.5
706.5 is the answer
-x + 2y = 6
6y = x + 18
Let's rewrite these equations.
-x + 2y = 6
6y - x = 18
If we multiply the second equation by -1 we can add both of them.
-x + 2y = 6
-6y + x = -18
Add:
-x + (-6y) + 2y + x = 6 + (-18)
2y - 6y + x - x = 6 - 18
-4y = -12
y = -12/-4
y = 3
Substitute y in the equation:
-x + 2y = 6
-x + 2.3 = 6
-x + 6 = 6
-x = 6 - 6
-x = 0
x = 0
Option B.
