What we know:
I = Invest (so we dont mess up on interest.)
So, I = $7,000
First Account is 4%
Second Account is 2%
End of the year David Earns $476 in interest
With percent's you can always turn them into a decimal.
--------------------------------------------------------------------------------------------------------------
The Question: How much was in each account?
--------------------------------------------------------------------------------------------------------------
Step by Step Answer:
I = amount invested at 4%
4% = 0.40
8% = 0.80
0.40 - $7,000 = 6999.6
0.80 - 6999.6 = 6998.8
6998.8 - 476
Amount in both accounts in total is 6522.80.

HAVE A FANTASTIC DAY!
Answer:
6 there are 6 motorcycles
Step-by-step explanation:
Let 'x' represent the total distance from point A to point B
During the first hour he gets 0.25 of the way there: 0.25x
During the second hour he covers an additional 0.2 of the distance: 0.2x
During the third hour, he covers 0.3 of the distance: 0.3x
The total distance the biker traveled is:
0.25x + 0.2x + 0.3x = (0.25 + 0.2 + 0.3)x = 0.75x
The biker has: x - 0.75x = (1 - 0.75)x = 0.25x of the total distance left to go.
Given:
The given statement are:
a. Eight less than the product of seven and x.
b. The sum of six and the product of three and d.
To find:
The expression for the given statements.
Solution:
a.
Product of 7 and x is 7×x = 7x.
Eight less than the product of seven and x is 7x - 8.
Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.
b.
Product of 3 and d is 3×d = 3d.
The sum of six and the product of three and d is 6+3d.
Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.
Given:
Irregular Shape:
Semi-circle and rectangle:
Area of a rectangle = l * w
Area of a semi-circle = (π r²)/2
Area of rectangle = 8 cm * 5 cm = 40cm²
Area of a semi-circle = (3.14 (4²))/2 = (3.14*16)/2 = 50.24/2 = 25.12cm²
4² is taken from diameter of 8cm divided by 2 to get the radius.
Total area = 40 cm² + 25.12 cm² = 65.12 cm²
