Hi there, Rukie! This problem can be solved by divided the number given by one of the ratios, and multiplying that answer by the other ratio. Since Bob invested the greater amount, we can divide his investment ($450) by 8, getting the answer of 56.25 (that's the unit of the ratio). We can then multiply that number by 7 to calculate Ellen's investment, which comes out to be $393 dollar and 75 cents. Hope that helps!

Answer:
y = 4x + 16
Step-by-step explanation:
You can replace the point coordinates in the given point-slope form to get ...
y - 32 = 4(x -4)
Then rearrange to put this into slope-intercept form.
y = 4x -16 +32 . . . . eliminate parentheses, add 32
y = 4x +16 . . . . . . . . simplify
Answer:
D
Step-by-step explanation:
Since KL = JL then the triangle is isosceles with base angles congruent, that is
∠ K = ∠ J = 8x + 5
The sum of the 3 angles in the triangle = 180°
sum the angles and equate to 180
8x + 5 + 8x + 5 + 5x - 19 = 180
21x - 9 = 180 ( add 9 to both sides )
21x = 189 ( divide both sides by 21 )
x = 9
Then
∠ J = 8x + 5 = 8(9) + 5 = 72 + 5 = 77°
Answer:
32.38 square m
Step-by-step explanation:
Diameter of semicircle = 5 m
Hence, radius = 5/2 = 2.5 m
Area of figure = Area of rectangle - 2 times area of one semicircle
Answer:
true if you mistyped it. 1/10 of it would be 7.055 not 7.005
