If the reserve rate is 8% and a bank receives a deposit of $7000, how much of
the $7000 is the bank free to lend?
A. $6440
B. $1400
C. $5600
D. $560
The bank can borrow $6440 based on the $7000 deposit.
What is defined as the reserve rate?The reserve ratio is the proportion of a commercial bank's deposits that it has to keep in cash as a safeguard in the event of mass customer withdrawals, as determined by the central bank. The reserve ratio is a crucial monetary policy tool used by the Federal Reserve in the United States to continue increasing the economy's money supply.The following deposit amount: $7000
Because the reserve rate is 8%, the bank will reserve 8% of the 7000. The remaining funds can be lent by the bank.
7000 × (8/100) = amount set aside
= $560
Thus, the reserve deposit is $560.
Amount the bank is willing to lend = 7000 - 560 = $6440
Thus, the bank can lend $6440 based on a deposit of $7000.

A sales tax is one that is levied on both the selling of products and services to businesses and on the purchases of those same goods and services by consumers. It's a form of consumption tax, which means it charges consumers for their purchases. Because sales taxes are typically passed on to customers at the moment of sale, it is classified as a consumption tax.
Solving the question:
Cost of the book = 9.95
Sale tax rate = 9%
Sale tax amount on 9.95 = 9.95/(9/100) = 9.12

Write a numerical expression using one of the properties that is equivalent to 2⁸
The numerical expression using commutative property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.
What is multiplication?Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a product.
Now the given exponent is,
2⁸
Now, 8 can be written as using associative property of addition,
8 = 2 + 2 + 2 + 2
Thus we can write,
2⁸ = 2^( 2 + 2 + 2 + 2 )
Using exponential property
x^(a + b) = x^a . x^b
Thus we get,
2⁸ = 2^2 . 2^2 . 2^2 . 2^2
Thus numerical expression for 2^8 = 2^2 . 2^2 . 2^2 . 2^2
Solving we get,
2^8 = 4 x 4 x 4 x 4 = 256
Thus, the numerical expression using exponential property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.

On a number line, suppose the coordinate of A is 0, and AR = 12. What are the possible coordinates of the midpoint of AR?
The possible coordinates for midpoints of the segment are
?
The midpoint of AR is (1/2 , 1).
Let the points be:
A(0,0) = (x₁,y₁)
B(1,2) = (x₂,y₂)
Midpoint = (x₁₊x₂/2) , (y₁₊y₂/2)
A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places.
= (0₊1/2) , (0₊2/2)

P = 2l + 2w
P = 2(x + 3) + 2(x - 2)
P = 2x + 6 + 2x - 4
P = 4x + 2
The area of a rectangle is found by multiplying the width by the length. We will use the FOIL method.
