Answer:
A. 1/2
Step-by-step explanation:
The original figure has a side of 4 and the reduced figure has a side of 2
4:2
What do we multiply to get from 4 to 2
4x =2
Divide each side by 4
4x/4 = 2/4
x = 1/2
The scale factor is 1/2
Answer:
180.82
Step-by-step explanation:
750,000 x .022=16,500 per year
16,500/365 days =45.2055/day
45.2055 x 4 days = 180.82
Answer:
$449.77
Step-by-step explanation:
The balance in account 1 can be found using the simple interest formula.
A = P(1 +rt)
A = $300(1 +0.045·3) = $340.50
The balance for account 2 can be found using the compound interest formula.
A = P(1 +r)^t
A = $100(1.03)^3 = $109.27
__
Darla's total balance will be ...
$340.50 +109.27 = $449.77
The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
