On January 11, Frank Morgan spent $228 on taxable merchandise at Wesley's Discount Clothing. The combined state and local sales
ryzh [129]

Answer:

Customer must pay a Total Amount of $240.

Step-by-step explanation:

Given:

Amount spent = $228

Sales tax = 5.25%

We need to find the Total Amount which need to be paid.

First we will find the amount paid in tax.

Amount paid in tax is equal to Percentage of sales tax multiplied with Amount spent and then divide by 100.

Framing the equation we get;

Amount paid in tax = \frac{5.25}{100}\times 228= \$11.97

Now Total Amount which need to be paid is equal to sum of Amount spent and Amount paid in tax.

Framing in equation form we get;

Total Amount which need to be paid = \$228 +\$11.97 = \$239.97

Rounding to nearest cent we get;

Total Amount which need to be paid = $240

Hence, Customer must pay a Total Amount of $240.

Can someone please help me solve this
Lady_Fox [76]
The "parent function" is y = (log to the base 2 of) x

The domain of this function is (0, infinity) (all real numbers greater than zero).

The range of this function is the same as above.

If you replace "x" with "x+1" in the parent function, the associated graph will look the same as that of the given function, EXCEPT that it will be translated by 1 unit to the left.

After this has happened, that "-3" will shift the entire new graph downward by 3 units.

Given: Quadrilaterals ABCD ~ EFGH , with measure of angle A = 47 degrees, measure of angle B = 39 degrees, and measure of angle
kaheart [24]

Answer:

The answer is below

Step-by-step explanation:

Two polygons are said to be congruent if they have the same size and shape that is their corresponding angles and sides are equal.

Hence since Quadrilaterals ABCD is congruent to EFGH, then their corresponding angles and sides are equal.

In quadrilateral ABCD:

∠A + ∠B + ∠C + ∠D = 360° (sum of angles in a quadrilateral)

Substituting:

47 + 39 + 112 + ∠D = 360

∠D + 198 = 360

∠D = 360 - 198

∠D = 162°

The image of Quadrilaterals ABCD and EFGH is not given but let us assume that they have the same orientation, hence:

∠A = ∠E = 47°

∠B = ∠F = 39°

∠C = ∠G = 112°

∠D = ∠H = 162°
