Mathematics
1 answer:
Schach [20]3 years ago

Answer:

20.6

Step-by-step explanation:

Since the diameter of each circle is 4, the dimensions of the rectangle is 8x12

The area of the whole rectangle is 96

Now we need to find the area of the circles

The area of 1 circle is 2^{2} *\pi =12.56...

So the area of all 6 circles is 12.56*6= 75.39...

So to find the area of yellow you have to subract the area of circle from the overall area of the rectangle

96-75.4=20.6

EASY QUICK POINTS!!!! Find the altitude of an equilateral triangle if each side of the triangle has the length of 6 meters!!!
KonstantinChe [14]

Answer:

5.20  to the nearest hundredth.

Step-by-step explanation:

The altitude line bisects the base of the triangle to form 2 right  angled triangles with hypotenuse = 6 and the base = 3.

So,  by the Pythagoras theorem the altitude is  calculated as follows:

6^2 = 3^2 + x^2

x^2 = 36 - 9 = 27

x = √27

= 5.20  to the nearest hundredth.

A new truck sells for $28,000depreciates (decreases in value) 13% each year. What is the Decay Factor, b?
sleet_krkn [62]
Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
