Answer:
x=5/4, y=7/4
Step-by-step explanation:
This is a similar triangles problem.
The first triangle (the smaller one) has the lengths 5, 8 and 7.
The second triangle (the lager one) has the lengths 5+x, 10, and 7+y
Let's first solve for x
In any similar triangles problem, you can make two ratios (all the ratios of the sides are the same)
since we don't know the measures for x and y first, we can use the ratio of the parallel lines (the bases) as the first ratio (8/10)
For the second ratio, it's smaller/bigger, so it'll be 5/(x+5)
here's the proportion
5/(x+5)=8/10
But before we multiply, we can simplify 8/10 to 4/5
so
5/(x+5)=4/5
Cross multiply
25=4x+20
5=4x
5/4=x
For y, we can do a similar process
We can use 8/10 or 4/5 again
and the ratio of the sides for y will be 7/(y+7)
7/(y+7)=4/5
35=4y+28
7=4y
7/4=y
Hope this helps!
800
You would multiply 10x80
Answer:
The correct answer is C= $99.400
Step-by-step explanation:
You need to sum all he has and then rest all he owes
The car has a balance of 20000 owed so 38000-20000=$18000 to sum
%195000+$5000+$1400+$180000=$219400
Then you rest what he owes= $219400-$120000=$99400
Thats Ben's net worth
The Answer is C=$99400
The car has a balance of 20000 owed so 38000-20000=$18000 to sum
Answer:
1.68 ft
Step-by-step explanation:
Let x be the radius
Arc length = 3.14x
Width = 2x
Height = [12 - (2x) - 3.14x]/2
= 6 - 2.57x
Area = 3.14x²/2 + 2x(6 - 2.57x)
Area = 12x - 3.57x²
dA/dx = 12 - 7.14x = 0
x = 1.6806722689
Height = 6 - 2.57x
= 1.6806722689
Answer:
x=-1
Step-by-step explanation:
-3x=-10+13 - -3x=3 - -3 = -1
