The ratio of inheritance is
.. sister : brother = 1.25 : 1 = 5 : 4
Then the sister receives 5/(5+4) = 5/9 of the total, $550,000.
Step-by-step explanation:
just see if this is right
f (x)+g (x)
f (x)= -3x^2 - 1---------(1)
g(x)= 4x - 2------------(2)
(1)+(2)
-3x^2 - 1+ 4x - 2
-3x^2+4x - 3

Step-by-step explanation:
L=®/3602πr
L=20/360×2×3.14×3
L=1.04
Answer:
63
Step-by-step explanation:
the numbers are in ratio 7 : 9 = 7x : 9x ( x is a multiplier )
given the sum of the numbers = 112 , then
7x + 9x = 112 , that is
16x = 112 ( divide both sides by 16 )
x = 7 , then
9x = 9 × 7 = 63 ← value of larger number
Answer:
The other angle is 60°
Their ratio is 1 : 2
Step-by-step explanation:
Let us revise some special angles
A pair of complementary angles is two angles their sum is 90°
A pair of supplementary angles is two angles their sum is 180°
In the question
∵ One angle of the pair of complementary angle = 30°
∵ The sum of the two complementary angles = 90°
→ Subtract 30° from 90° to find the other angle
∴ The other angle = 90° - 30° = 60°
∴ The other angle is 60°
To find the ratio of them put them in the form of the ratio, then simplify the ratio to its simplest form
∵ Their ratio = 30 : 60
→ Divide both sides by 10
∴ Their ratio = 3 : 6
→ Divide both sides by 3
∴ Their ratio = 1 : 2
∴ Their ratio is 1 : 2
