Step-by-step explanation:
well the answer is 254.66 if you needed the answer and not just the explanation
Answer:
254.66
Step-by-step explanation:
Total before tax:
225.45 +12.55 = 238
To get tax, you multiply the total times the percent
(7%=.07)
238 x .07 = 16.66 (this is the amount for tax)

write the equation of a line in point slope form that passes through (6,5) and (-3,2)
Answer:
[tex]y-5 = \frac{1}{3}(x-6)[/tex]
Step-by-step explanation:
Point Slope Form:
[tex]y-y_{1} = m(x-x_{1} )[/tex]
where m = slope
First, you have to find the slope of the line which is the difference in y values divided by the difference in x values.
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
[tex]m = \frac{2-5}{-3-6}[/tex]
[tex]m = \frac{-3}{-9} \\m = \frac{1}{3}[/tex]
Then plug in the values from either point to complete your equation of the line:
[tex]y-5 = \frac{1}{3}(x-6)[/tex]

1. Is (2, 4) a solution of the equation y = x - 2?
Answer:
No.
Step-by-step explanation:
If you plug in the numbers for the X and Y value, you will not receive the correct answer.
y = x - 2
(2, 4)
4 = 2 - 2
So, NO (2, 4) is NOT a solution of the equation y = x - 2.

Jaime has 636 blocks. About how many blocks does he have ?
a. 500
B.600
C.700
D.800
Answer:
B.) 600
Step-by-step explanation:
if you are rounding to the nearest hundred value you would get 600 because the 3 in 638 will round down to 600
it can not be A because it is to far down from the number line
it can not be C or D because they are to far up on the number line
So the correct answer has to be B-600
if the 2nd number is 5 or more you will always round up.
if the 2nd number is 4 or less you will have to round down.
After rounding off Jaime has (B) 600 blocks with him.
What is rounding off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. The crucial figures are preserved when numbers are rounded off. to reduce the number of significant digits in a number to an approximate value. Round off the numbers 15.4 to 15, 15.51 to 15.5 or 16, 0.499 to 0, and 970,000 to 1 million.So, rounding off 636:
We can easily tell that after rounding off, the number of blocks will be:

Yesterday, Bethany sent 60 text messages. She said that 15% of those messages were to her best friend. How many text messages did Bethany send to her friend yesterday
(Please explain)
Answer: 9 Text messages sorry if i'm wrong
Step-by-step explanation: OK so first, this can be answered by using division and variables.
DIVIDE
60 / 10 = 6 which means 6 = 10%
DIVIDE AGAIN
6 / 2 = 3 which is 5%
ADD AND SIMPLIFY
6 + 3 = 9 or 9 = 15%

Someone solve this plz
Answer:
z= 23°
y= 120°
Step-by-step explanation:
For z, the measures of the angles are alternate interior angles, they equal each other. So, the equation would be:
66= 3z-3
Step 1- Add 3 to both sides.
66= 3z-3
+3 +3
69= 3z
Step 2- Divide both sides by 3.
69= 3z
3 3
z= 23°
For y, the measures of 66 and y are alternate exterior angles, they sum up to 180 degrees. So, the equation would be:
180= 60+y
Step 1- Subtract 60 to both sides.
180= 60+y
-60 -60
y= 120°

A large group of students took a test in physics and the final grades have a mean of 70 with a standard deviation of 10. If the graph of the scores has normal distribution, what percentile would a student be in if they earned an A on the test? (a is a score ≥ 90)
Answer:
The student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
The graph of the scores has normal distribution and percentile would a student be in if they earned an A on the test is 97.72%
What is Normal Distribution?An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the centre of the range.
Normal distributions are symmetric, uni-modal, and asymptotic, and the mean, median, and mode are all equal
A data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean
Given data ,
To determine the percentile a student would be in if they earned an A (a score ≥ 90) on the physics test, we need to calculate the z-score corresponding to the score of 90 and then find the percentile associated with that z-score.
The z-score is a measure of how many standard deviations a particular value is away from the mean in a normal distribution
z = (x - μ) / σ
where x is the value, μ is the mean, and σ is the standard deviation
In this case, we have:
x = 90 (the score for an A)
μ = 70 (the mean)
σ = 10 (the standard deviation)
Plugging these values into the z-score formula
z = (90 - 70) / 10 = 20 / 10 = 2
The z-score of 2 indicates that the score of 90 is 2 standard deviations above the mean in a normal distribution
The percentile associated with a z-score of 2 is approximately 97.72%
Hence , if a student earned a score of 90 or above on the physics test, they would be in the 97.72th percentile

Rewrite as a simplified fraction. 2.2666... = ?
Answer:
[tex]\frac{34}{15}[/tex] or [tex]2 \frac{4}{15}[/tex]
Step-by-step explanation:
Let x equal the decimal. Set up two equations such that the digits after the decimal point are identical.
100x = 226.6666...
10x = 22.6666...
Subtracting the two equations, we have:
90x = 204
x = 204/90
