Help me with Alims sales tax problem

wlad13 [49]

First you need to find the amount for each of the items, then total it up:

T-shirts> 9.50 x 2 = 19
Socks> 7.95 x 3 = 23.85
Shoes> 49.95
Total: 19 + 23.85 + 49.95 = $92.80

Next find the tax:

(to find the taxes you multiply the total by the percent)
92.8 x 0.06 = 5.57
-- then add the amount to your item total
92.8 + 5.57 = 98.37

~OR~

You could multiply the item total by 1.06 so that you wouldn't have to add to taxes to the previous total because it is already part of the equation

92.8 x 1.06 = 98.37

Describe in words the region of double-struck R3 represented by the inequality. 0 ≤ z ≤ 7 The inequality 0 ≤ z ≤ 7 represents al

qwelly [4]

Answer:

All points between z = 0 and z = 7 along the z-azis in R3 x-y-z plane

Step-by-step explanation:

The inequality 1 $\le$ z $\le$ 7 represents all sets of points on the z-axis in the R3 plane that lies bewteen z = 0 and z= 7.

It is represents a line segment joining two point z= 0 and z=7 along z- axis in the R3 plane, while x=0 and y=0 on the x-y plane.

Horizontal lines e and f are cut by vertical lines a and b. At the intersection of lines a and e, the uppercase right angle is (

Paul [167]

Answer: $y=90\°$

Step-by-step explanation:

Based on the description given in the exercise, you can draw the horizontal lines "e" and "f" cut by the vertical lines "a" and "b".

By definition, when a horizontal line and a vertical line intersect each other, the angle formed by this intersection measures 90 degrees.

A "Right angle" is defined as an angle that measures 90 degrees.

Therefore, if a vertical line intersects a horizontal line, you can say that they are perpendicular.

You can observe in the image attached that the vertical lines "a" and "b" cut the horizontal lines "e" and "f". Therefore, since $a||b$ and $e||f$ , all the angles formed by this intersections measure 90 degrees.
