So for the triangle you would use the formula A= 1/2 bh (b represents the measurement of the base, h represents the height)
A= 1/2 30(40)
A= 1/2 1200
A=600
Now for the rectangle you use the formula A= l x w (l represents length, w means width)
A= 100 x 40
A= 4000
Now you just add the two answers together
A= 4000 + 600= 4600
Equation of a line in slope-intercept form is y = mx + b
If it has a slope of 1/2, you set m = 1/2. If it has a y-int at the origin, you set b = 0
Put it all together:
y = 1/2x + 0
or
y = 1/2x
The equation for the area of a triangle is (base × height)/2.
In this triangle your base is 12 and your height is 8.
Therefore you do (12 × 8)/2 = 96/2 = 48
I hope this helps!
Answer:
no
Step-by-step explanation:
To get the smallest amount one can invest in 3 years at a rate of 5% to obtain £8000 we use the compound formula given by:
A=p(1+r/100)^n
where:
A=future amount
p=principle
r=rate
n=time
From the question:
A=£8000, r=5%, n=3
thus plugging the values in the formula and solving for p we get:
8000=p(1+5/100)6n
8000=1.157625p
thus
p=6910.700
Hence the smallest amount is £6910.70~£6910
