Donis bought a t-shirt for $15 and jeans for $35.50. If the sales tax rate is 8.25%. What is the sales tax for the t-shirt and jeans in dollars and cents? *
====================================================
Explanation:
15+35.50 = 50.50 dollars is the total before tax is applied.
Take 8.25% of this to get
0.0825*50.50 = 4.16625
and this rounds to 4.17, which is the amount of sales tax charged.
$4.17 = 4 dollars + 17 cents
---------
Extra info:
The grand total will be 50.50+4.17 = 54.67
Another way to get the grand total is to multiply 1.0825 by the previous subtotal (50.50) getting 50.50*1.0825 = 54.66625 and that rounds to 54.67
The multiplier 1.0825 effectively means "increase by 8.25%"

y + 6 = 4/3(x - 2)
First, distribute the 4/3
y + 6 = 4/3x - 8/3
Subtract 6 from both sides.
y = 4/3x - 26/3
-26/3 is the y-intercept so start the graph at coordinate (0, -26/3)
After you plot the y-intercept, add 4 to they y-coordinate and 3 to the x-coordinate of the y-intercept to get the next point.
0 + 3 = 3
-26/3 + 4 = -14/3
The next point should be at (3, -14/3)
Add as many points as your professor requires.
Answer:
(0, -26/3) (3, -14/3)
Step-by-step explanation:
y+6 = 4/3x - 8/3
y = 4/3x - 26/3
(0, -26/3)
-26/3 + 4 = -14/3
(3, -14/3)

-2 (4z - 4) = 10 - 6z
I think it’s z=1 hope this helps
Answer:
z=-1
Step-by-step explanation:
-2(4z-4)=10-6z
First, distribute the -2 into the parenthesis to get:
-8z+8=10-6z
Then, add 8z to each side to eliminate it from the left side to get:
8=10+8z-6z
Simplify the right side and combine the z's:
8=10+2z
Subtract 10 from BOTH sides to get:
-2=2z
Finally, to get z alone, divide everything by 2 to get:
-1=z or z=-1

Terry bought a home that home that had an attached one-car garage and a screened porch that spanned the length of the home. If the garage measured 16' in depth which was half the depth of the house and the screened porch was 64' in width, what is the GLA of the house?
Answer: 2048SF
Step-by-step explanation:
From the question, we are informed that Terry bought a home that home that had an attached one-car garage and a screened porch that spanned the length of the home.
We are further told that the garage measured 16' in depth which was half the depth of the house and the screened porch was 64' in width. Since the garage measured 16' in depth which was half the depth of the house, this means that the total depth of the house will be:
= 16' × 2
= 32'
Therefore, the GLA of the house will then be the full depth of the house multiplied by the screened porch. This will be:
= 32' × 64'
= 2048SF
through: (-2,-2), slope = 1/2
Write the slope-intercept form of the equation of the line through the given point with the given slope.
Answer:
The answer is
[tex]y = \frac{1}{2} x - 1[/tex]Step-by-step explanation:
To find an equation of a line given a point and slope we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-2,-2) and slope = 1/2
The equation of the line is
[tex]y + 2 = \frac{1}{2} (x + 2) \\ y + 2 = \frac{1}{2} x + 1 \\ y = \frac{1}{2} x + 1 - 2[/tex]
We have the final answer as
[tex]y = \frac{1}{2} x - 1[/tex]

A crate to ship boxes of baseballs can hold 4 boxes that are each (6 x 6) * 2. How
many baseballs can be shipped in the crate, if each baseball takes a 1x1x I space?
Show your thinking using words, numbers, or labeled sketches.
Answer:
Each crate can contain 288 baseballs.
Step-by-step explanation:
Since one baseball takes up 1 × 1 × 1 space, and each box has 6 × 6 × 2 units of space, then the number of baseballs in one box is 6 × 6 × 2 ÷ 1 × 1 × 1 = 72 baseballs.
So, 72 baseballs can be contained in one box.
Now, since each crate contains 4 boxes, the number of balls contained in each crate is 1 × 4 boxes = 1 × 4 × 72 baseballs = 288 baseballs.
So each crate can contain 288 baseballs.

An object is moving at a speed of 63 centimeters every 2 days. Express this
speed in meters per hour. Round your answer to the nearest hundredth.
Given :
Distance covered by object , D = 63 cm .
Time taken to cover distance D , t = 2 days .
To Find :
The speed of object in m/s .
Solution :
First we will convert all units into m and hours .
D = 63 cm = 0.63 m .
[tex]t=2\ days =2\times 24\ hours =48\ hours[/tex] .
Now , speed is :
[tex]s=\dfrac{D}{t}\\\\s=\dfrac{0.63}{48}\ m/hours\\\\s=0.013\ m/hours[/tex]
Hence , this is the required solution .

Question 8
A science club rents a bus for a trip to a state park. The bus rental is
$350, and admission to the park is $8 per person. The cost of the bus
rental will be shared equally. Write an expression that can be used to
determine the cost of the trip for each club member.
Let m be the number of club members.
Since they will share the $350 cost of the bus equally, then each member pays 350/m dollars for their share of the bus cost.
The admission is $8 per person, so the total cost per person is;
[tex]\frac{350}{m} +8[/tex]

2) AC = x + 2, BC = 1, and AB = 2x - 4.
Find x, AB, and AC.
Answer:
x = 5 AB = 6 AC = 7Step-by-step explanation:
Points A, B, and C are collinear and point B is between A and C then
AB + BC = AC
2x - 4 + 1 = x + 2
2x - 3 = x + 2
+3 +3
2x = x + 5
-x -x
x = 5
AB = 2x - 4 = 2×5 - 4 = 10 - 4 = 6
AC = AB +BC = 6 + 1 = 7
