A $12 t- shirt is on sale for 40% off at a store in Mississippi. Sales Tax on Mississippi is 9%. How Much Will The t- shirt end

STALIN [3.7K]

Let's calculate how much for the $12 t - shirt after the discount.

First, convert 40% into a decimal,

$40\% = 0.4$

Next, multiply the cost by the discount,

$12 \times 0.4 = 4.8$

Lastly, subtract the amount discounted,

$12 - 4.8 = 7.2$

~~

Now

Let's calculate the amount after the sales tax,

First convert 9% to a decimal,

$9\% = 0.09$

Next, multiply the cost of the t - shirt by the sales tax,

$7.2 \times 0.09 = 0.648 = 0.7$

Lastly, add the amount of sales tax to the price of the t - shirt,

$7.2 + 0.7 =7.9$

~~

Answer : the t - shirt will be $7.90 after everything.

Determine whether the following statement is true or false. Explain your reasoning. Jordan says that when solving the equation 4

Mkey [24]

Answer:

The correct option is;

C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing

Step-by-step explanation:

In other to solve the equation 4·b + 3 = 11, we have;

By the subtraction property of equality, we have;

Firstly we subtract 3 from both sides gives;

4·b + 3 - 3= 11 - 3

Next we apply the division property of equality, we have;

Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,

Dividing both sides by 4, gives;

4·b/4 = 8/4

b = 8/4 = 2

The solution to the equation, 4·b + 3 = 11 is b = 2.

Calculate the Zscore of $80

gayaneshka [121]

The Z-score (z) is calculated according to the formula: z = (x - μ) / σ

Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.

x = 80, μ = 5, σ = 4

z = (80 - 5) / 4

z = 75 / 4 = 18.7500

Z-score is 18.7500
