Price is $20.00 Sales Tax is 4% What is the total cost?
Answer:
your answer is correct
Step-by-step explanation:
i don't know why i it didn't work
If the price of an item is $20.00 with a sales tax of 4%, the total cost of the item is $20.80.
How the total cost is determined using the sales tax:The total cost involves adding the price and the sales tax amount.
We can compute the total cost by determining the sales tax factor using the sales tax rate as follows:
The price of the item = $20.00
Sales tax = 4% = 0.04 (4/100)
The sales tax factor = 1.04 (1 + 0.04)
Thus, the total cost, including the price and the sales tax, is $20.80 ($20 x 1.04).

how do I solve for x here??
I just need help with finding x
Answer:
x = 15
Step-by-step explanation:
The solution to any problem is found by making use of the relations you know between the parts of the problem. Here, values of x relate to the arc measures around a circle. The relation you know is the sum of the arcs around a circle is 360°. Using this relation, you can write the equation ...
7x° +4x° +6x° +7x° = 360°
The equation can be solved for x by making use of the rules of algebra.
24x = 360 . . . . . . . . . . . . . . divide by °, collect terms
x = 15 . . . . . . . . . . . . . . . . divide by 24

SV is a midsegment of △RTU.
If TU=y+38 and SV=y–9, what is the value of y?
Answer:
y = 56
Step-by-step explanation:
the midsegment SV is half the length of the side TU , that is
y - 9 = [tex]\frac{1}{2}[/tex] (y + 38) ← multiply both sides by 2 to clear the fraction
2y - 18 = y + 38 ( subtract y from both sides )
y - 18 = 38 ( add 18 to both sides )
y = 56

BRAINALEST!!!!!!!!!! 1/2 + 2/9 + 1/6
Answer:
8/9
Step-by-step explanation:
Solving
Step 1: Find the LCM of the denominators 2, 9, and 6:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60As you can see, the LCM of these denominators is 18Step 2: Convert each fraction into an equivalent decimal with denominator as 18.
[tex]\frac{1}{2} = \frac{x}{18}[/tex], [tex]\frac{1*9}{2*9}= \frac{9}{18}[/tex] [tex]\frac{2}{9} = \frac{x}{18} , \frac{2*2}{9*2} = \frac{4}{18}[/tex] [tex]\frac{1}{6} =\frac{x}{18} , \frac{1*3}{6*3} =\frac{3}{18}[/tex]Step 3: Add the fractions.

Answer:
8/9
Step-by-step explanation:
Take LCM of denominators 2, 9 & 6 = 18
1/2
[ 18/2 = 9 ]
Multiply 9 to both numerator and denominator,
1/2 * 9/9
= ( 1*9 )/( 2*9 )
= 9/18
2/9
[ 18/9 = 2 ]
Multiply 2 to both numerator and denominator,
2/9 * 2/2
= ( 2*2 )/( 9*2 )
= 4/18
1/6
[ 18/6 = 3 ]
Multiply 3 to both numerator and denominator,
1/6 * 3/3
= ( 1*3 )/( 6*3 )
= 3/18
( The denominator need to be same in order to add the fractions )
1/2 + 2/9 + 1/6
= 9/18 + 4/18 + 3/18
= ( 9 + 4 + 3 )/18
= 16/18
16 = 2*8
18 = 2*9
16/18
= ( 2*8 )/( 2*9 )
= 8/9

5% commission rate of 14.98 is what?
Answer:
$0.75
Step-by-step explanation:
To find the answer we simply multiply the amount of money earned by the percentage.
So the total amount of money = $14.98
And the percentage = 5%
But I order to calculate this we must first turn the percentage into a decimal. To do this we decide the number of the percentage by 100
In this case that is 5/100=0.05
We can now multiply this by the amount of money to get 0.05*14.98=0.749
We then round our answer to two decimal places (because money can not go past two) to get $0.75

A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The relationship between Length and Weight has an Rsquared of 58.6%. Write a sentence (in context) summarizing what the Upper R squared says about this regression.
Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.
Question 10
Jordan is trying to graph the following inequality: y < 2x – 10
He plugs in (0, 0) like this: 0 < -10
He decides that this is true, so he shades the side with (0, 0).
What did Jordan do wrong?
Answer:
Step-by-step explanation:
"0 < -10" is actually false, so Jordan has shaded the wrong side.
which piece wise function is graphed below
Answer:
Option A
Step-by-step explanation:
Here is how to approach the problem:
We see that all our restrictions for all four answer choices are relatively the same with a couple of changes here and there.
One way to eliminate choices would be to look at which restrictions don't match the graph.
At x<-5, there is a linear function that does have a -2 slope and will intersect the x axis at -7. The line ends with an open circle, so any answer choice with a linear restriction of x less than or equal to -5 is wrong. This cancels out choices C and D.
Now we have two choices left.
For the quadratic in the middle, the vertex is at (-2,6) and the vertex is a maximum, meaning our graph needs to have a negative sign in front of the highest degree term. In our case, none of our quadratics left are in standard form, and instead are in vertex form.
Vertext form is f(x) = a(x-h)^2 + k.
h being the x-coordinate of the vertex and k being the y-coordinate.
We know that the opposite of h will be the actual x-coordinate of the vertex, so if our vertex is -2, we will see x+2 inside the parenthesis. This leaves option A as the only correct choice.
