A store charges 8% tax on every dollar spent. The table shows the tax amount for several different purchases. How much tax would there be on a $200 purchase?
Answers
Answer:
This online sales tax calculator solves multiple problems around the tax imposed on the sale of goods and services.
Answer:
$1.6
Step-by-step explanation:
If 8% is charged for each $. Tax charged for $1 = 8/100 which is equal to 0.08.
Tax Amount payed
$0.08 -----------> $1
$y ------------> $20
This is directly proportional. Therfore cross multiply the values.
y × 1 = 20 × 0.08
y × 1 = 1.6
y = 1.6/1
y = 1.6
Therefore $1.6 is the amount of tax charged for $20

John keeps track of his father's driving to pass the time on a trip to Grandma's. He records the distance each hour, and he will graph the results. If the pattern of mileage change continues, how far will they have driven in 11 hours?
Hours Miles (x, y)
1 70 (1, 70)
2 140 (2, 140)
3 210 (3, 210)
4 280 (4, 280)
560 miles
700 miles
350 miles
770 miles
Answers
Answer:
770 miles
Step-by-step explanation:
First, find the slope (m) of the pattern, using any two points from your data set.
Slope (m) = [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(1, 70) and (3,210)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{210-70}{3-1}\\m=\frac{140}{2}\\m=70[/tex]
y = mx + b
y = 70x + b
(1, 70)
y = 70x + b
70 = 70(1) + b
70 = 70 + b
-70 -70
0 = b
y = 70x + b OR y = 70x
Now we find how he has driven in 11 hours
y = 70x
y = 70(11)
y = 770
Therefore, he will have driven 770 miles in 11 hours.
Hope this helps!

On a math test a student, Sarah, has to identify all the coefficients and constants of the expression 6n + 5 +m. Sarah says that is a coefficient and 5 is a constant. Identify all the coefficients and constants of the expression. What error might Sarah have made?
Answers
Hi! I hope you're enjoying your day!
A coefficient is a number before a variable. (for example, 12d)
A variable is a letter (for example, a)
A constant is a number with no variables (not 6s, but 6)
Let's identify the coefficients & the constants here.
We have the expression
[tex]\bold{6n+5+m}[/tex]
And we know that a coefficient is a number before a variable.
So we know the coefficient (6)
Now, a constant is a number with no variables multiplied by it (or divided by it)
Hence, the answer is
[tex]\boxed{\boxed{\bold{coefficient-\:6\:;constant\:-5\:and\:Sarah's\;right}}}[/tex]
Hope everything is clear.

explanation:
formula for rectangle: length * width
17 * 3 + 2* 951 + 1869Answer:
The upright rectangle is the shape we're going to find the area of first;
Formula for area of rectangle;
A = BH
where b is the base, and h is the height
plug in the actual values:
A = BH
A = 17(3)
A = 51
Now let's find the area of the rectangle below;
Using the formula we applied to the upright rectangle;
A = BH
Though first, we need to find the height.
The total height of the two rectangles combined is 17, the height of just the upright rectangle is 15. So we subtract the two to get the height of the bottom rectangle, (17 - 15) = 2
A = 9(2)
A = 18
Now we add both of their sums;
51 + 18 = 69 ft^2, is your answer.
