Answer: $100,000
<u>Step-by-step explanation:</u>
Land + Stocks + Bonds + Savings = 100%
+ 0.1x + 
+ 35,000 = 1.00x
= 0.5x + 0.1x + 0.05x + 35,000 = 1.00x
= 0.65x + 35,000 = 1.00x
35,000 = 0.35x
100,000 = x
Answer:
-20
Step-by-step explanation:
Replace X by 3
f(3) = -2(3)^2+ (3)-5 = -20
Answer:
value of x = 5.8 mm
Step-by-step explanation:
We have given,
Two right triangles EDH and EDG.
In right triangle EDH, EH = 56mm , DH = 35 mm
Using Pythagoras theorem we can find ED.
i.e EH² = ED²+DH²
56²=ED²+35²
ED²=56²-35²
ED = √(56²-35²) = 7√39 = 43.71 mm
Now, Consider right triangle EDG
Here, EG=44.8mm , GD = x+4 and ED = 7√39
Again using Pythagoras theorem,
EG² = ED² + DG²
44.8²= (7√39)²+ (x+4)²
(x+4)² = 44.8² - (7√39)²
x+4 = √(44.8² - (7√39)²)
x+4 = 9.8
or x = 9.8 - 4 = 5.8 mm
Hence we got the value of x = 5.8 mm
