In January, Joanna deposited $250
into her savings account. In
February, she deposited an
additional $100. If her account has
an APR of 6% compounded monthly,
how much interest did Joanna earn
in the first two months?

Answers

The interest that Joanna earned in the first two months is $4.26.

What is the interest earned?

Interest earned in the first month = future value - amount deposited.

Future value = amount deposited x (1 + monthly interest)

Monthly interest = 6/12 - 0.5% = $252.50

Interest = $252.50 = 250 = $2.50

Interest earned in the second monthly = future value of the first month + amount deposited x (1.005)

(252.50 + 100) x 1.005 = 354.26

Interest = 354.26 = 352.50 = $1.76

Total interest = $1.76 + $2.50 = $4.26

using
substitution.
y = -2x + 13
4x + 8y = 20
A)(-7,-1)
B)(4,5
C)(7,-1)
D)(-3,7)

Answers

Answer: C) x = 7, y = -1

Step-by-Step Explanation:

=> y = -2x + 13 (Eq. 1)
=> 4x + 8y = 20 (Eq. 2)

Substitute value of ‘y’ from Eq. 1 in 2 :-

4x + 8y = 20
4x + 8(-2x + 13) = 20
4x + -16x + 104 = 20
-12x + 104 = 20
-12x = 20 - 104
-12x = -84
12x = 84
x = 84/12
=> x = 7

Substitute value of ‘x’ in Eq. 1 :-

y = -2x + 13
y = -2(7) + 13
y = -14 + 13
=> y = -1

Therefore, x = 7, y = -1 which can be written in an ordered pair as (7,-1).

(8 kg 300 g 120 mg) − (3 kg 500 g 480 mg) 4 kg 799 g 640 mg

Answers

The value of (8 kg 300 g 120 mg) − (3 kg 500 g 480 mg) is; 4 kg 799 g 640 mg

How to carry out Unit Conversions?

We want to find the value of;

(8 kg 300 g 120 mg) − (3 kg 500 g 480 mg)

First of all, let us convert all units to kg as;

120 mg = 0.00012 kg

300 g = 0.3 kg

Thus;

8 kg 300 g 120 mg = 8 + 0.3 + 0.00012 = 8.30012 kg

Similarly, converting the second expression;

480 mg = 0.00048 kg

500 g = 0.5 kg

Thus;

3 kg 500 g 480 mg = 3 + 0.5 + 0.00048 = 3.50048 kg

Thus, we have;

8.30012 kg - 3.50048 kg = 4.77964 kg

Breaking down this gives;

4 kg 799 g 640 mg

It give the probability of each outcome, and each outcome is represented by a countable number.

A car and a motor bike are priced at $33090. If the value of the car is three times the value of the motor bike, how much is the car worth?

Answers

So, you have the price combined for the motorcycle and car, and the car is 3x the amount of the bike. Here, we can separate their prices into fractions/percents (whatever works easiest for you). So, the car is 3/4 (75%) of the price, and the motorcycle is 1/4(25%) of the price.

Therefore, to find the price of the motorcycle, you multiply 33090 x 1/4 or .25 which equals $8272.50


And the car is 33090 x 3/4 or .75 which equals $24817.50.

The car is $24817.50

A (-∞, -6)
B (-∞, 6)
C (-6, ∞)
D (6, ∞)

Answers

The interval which the function is negative is (-∞, -6)

How to determine the interval?

The equation of the function is given as:

[tex]g(x) = \sqrt[3]{x + 6}[/tex]

When the function is negative.

It means that g(x) is less than 0

i.e. g(x) < 0

So, we have:

[tex]\sqrt[3]{x + 6} < 0[/tex]

Take the cube of both sides

x + 6 < 0

Subtract 6 from both sides

x < -6

The above represents a value from negative infinity to -6

i.e.  (-∞, -6)

Hence, the interval which the function is negative is (-∞, -6)

(2x² - 3x) / 7 is the quotient of the given division.

What is simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

To divide by a fraction, we can multiply by its reciprocal. So to simplify the expression:

((2x-3)/x ) / (7/x²)

We can multiply the numerator by the reciprocal of the denominator:

((2x-3)/x ) * (x²/7)

Simplifying this expression, we can cancel out the common factor of x in the numerator and denominator:

(2x-3) * (x/7)

Expanding the product:

(2x² - 3x) / 7

Therefore, the quotient of ((2x-3)/x ) / (7/x^2) is (2x² - 3x) / 7.
