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%"
what is w in this−4(w+1)=−24
Answer:
w = 5
Step-by-step explanation:
Given
- 4(w + 1) = - 24 ( divide both sides by - 4 to isolate w + 1 )
w + 1 = 6 ( subtract 1 from both sides )
w = 5

Solve the equation
|-9-7x|=|23-7x|.
Graph the solutions, if possible.
Answer: No Solution
Step-by-step explanation:
When there are absolute values on both sides, you simply just get rid off the signs. (Normally, it results in positive and negative on the other side)
SOLVE:
Given
|-9-7x|=|23-7x|
No absolute value sign
-9-7x=23-7x
Add 7x on both sides
-9=23
ANSWER:
This is no solution, because -9≠23
3x - y = 2
and
2x + y = 4
[tex]\frac{3}{1}[/tex]Answer:
Step-by-step explanation:
3x-y = 2
2x+y =4
put them into slope intercept form
y=3x-2
y=-2x+4
Now, you can either graph it or use substitution
3x-2 = -2x+4
+2x +2x
5x -2 = 4
+2 +2
5x = 6
5x/5 = 6/5
x = 6/5
3x -2 = y
3(6/5) -2 = y
3 x 6 / 1 x 5 = 18/5
3 3/5 -2 = 1 3/5
Let me know if it's wrong.
Hope this helps
It’s suppose to be reduced in improper fractions ♀️
3(x-5)/2 = 2(x+5)/3
Answer:
13.
Step-by-step explanation:
Cross multiply: [tex]\frac{3x-15}{2}=\frac{2x+10}{3}[/tex]
Remove the brackets: 3(3x-15) = 2(2x+10)
Move the terms: 9x-45 = 4x+20
Collect like terms and calculate: 9x-4x=20+45
Divide both sides: 5x = 65

Answer: [tex]\frac{1}{\sqrt[3]{x} }[/tex]
Step-by-step explanation:
Since the base of the exponents are the same, we can go ahead and subtract the exponents.
[tex]\frac{x^{\frac{5}{6}} }{x^{\frac{7}{6} }}[/tex] [subtract exponents]
[tex]x^{-\frac{2}{6} }[/tex] [simplify exponent]
[tex]x^{-\frac{1}{3}}[/tex] [write in radical form]

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Answer:
9.25
Step-by-step explanation:
5(0.3) = 1.5
20-1.5=18.5
18.5÷2=9.25
Answer:
y = 9.25Step-by-step explanation:
5x + 2y = 20
when x = 0.3 we have
5(0.3) + 2y = 20
1.5 + 2y = 20
Using the subtraction property subtract 1.5 from both sides of the equation
That's
1.5 - 1.5 + 2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]
We have the final answer as
y = 9.25Hope this helps you

Here's how to find the distance between any two points.
Subtract the x values.
5-(-1)=5+1=6
Square that.
6²=36
Subtract the y values.
0-4=-4
Square that.
-4²=16
Add the two numbers you got.
36+16=52
And square root it.
√52≈7.2.

The local coffee house reported losses of -⅜ of their normal profit each day for 3 days. If their normal profit is $350 a day how much money was lost for the 3 days?
Answer:
Total loss in three days = $393.75
Step-by-step explanation:
Given:
Loss amount = [-3/8] of normal profit
Normal profit per day = $350
Find:
Total loss in three days
Computation:
Total loss in three days = 3 [Normal profit per day][Loss amount]
Total loss in three days = 3 [350][3/8]
Total loss in three days = 3[131.25]
Total loss in three days = $393.75
To make lemonade , Kate uses 1 cup of lemon juice and 2 cups of sugar. If she makes a larger amount of lemonade with 10 cups of sugar, how many cups of lemon juice does she need?
Answer:
5 cups
Step-by-step explanation:
Answer:
1/2 : 1
2 : 4
3 : 6
Notice that every ratio consists of a number and double the number.
For 1/2 cup lemon juice, use 1 cup sugar.
The amount of sugar is twice the amount of lemon juice.
The ratio is 1:2
Since you are told the ratio is 1:r, that means r is 2.
The unit rate is 2 cups sugar per cup of lemon juice.

What is the product of –5 and –8?
–40
–13
13
40
Answer:
40
Step-by-step explanation:
This is the answer because:
1) Whenever you are multiplying negative integers, remeber these rules:
Negative x Positive = Negative
Positive x Negative = Negative
Negative x Negative = Positive
Positive x Positive = Positive
2) Since -5 and -8 are both positive numbers, the answer will be a positive product:
5 x 8 = 40
Therefore, the answer is 40.

Answer:
(C) [tex]h = \frac{2a}{b}[/tex]
Step-by-step explanation:
Here we have the formula for the area of a triangle: [tex]A = \frac{1}{2}bh[/tex]. Our goal is to isolate h on one side of the equation.
To do this, let’s treat the rest of the equation as if there were no variables.
Multiply both sides by 2:
[tex]2a = bh[/tex]
Divide both sides by [tex]b[/tex]:
[tex]\frac{2a}{b} = h[/tex]

make f the subject of the formula c=[tex]\frac{5(f-32)}{9}[/tex]
Answer:
[tex]f=\frac{9c}{5}+32[/tex]
Step-by-step explanation:
[tex]c=\frac{5\left(f-32\right)}{9}[/tex]
Switch sides:
[tex]\frac{5\left(f-32\right)}{9}=c[/tex]
Multiply both sides by 9:
[tex]\frac{9\times5\left(f-32\right)}{9}=9c[/tex]
[tex]5\left(f-32\right)=9c[/tex]
Divide both sides by 5:
[tex]\frac{5\left(f-32\right)}{5}=\frac{9c}{5}[/tex]
[tex]f-32=\frac{9c}{5}[/tex]
Add 32 to both sides:
[tex]f-32+32=\frac{9c}{5}+32[/tex]
[tex]f=\frac{9c}{5}+32[/tex]

67+k = 83
solve for k
no work needed
Answer:
k = 16
Step-by-step explanation:
Isolate the variable, k. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Subtract 67 from both sides of the equation:
k + 67 = 83
k + 67 (-67) = 83 (-67)
k = 83 - 67
k = 16
16 is your answer for k.
