Relative error = absolute error / measured speed
Relative error = 1/52 = 0.01923

John is buying a new work uniform. He used a 25% off coupon on a pair of boots that were $80. He also bought a belt that was 15% off. In total, John spent $120.25.
How much was the original price of the belt?
Answer:
$70.88
Step-by-step explanation:
He bought the boots for $80*75% = $80*0.75 = $60
Let x = the original price of the belt
He spent x * 85% = 0.85x for the belt
total cost = 60 + 0.85x = 120.25
0.85x = 120.25 - 60 = 60.25
x = 60.25/0.85 = $70.88

evaluate the expression 10^2+(3+5)^2-5
Hey there!
10^2 + (3 + 5)^2 - 5
= 10 * 10 + (3 + 5)^2 - 5
= 100 + (8)^2 - 5
= 100 + (8 * 8) - 5
= 100 + 64 - 5
= 164 - 5
= 159
Therefore, your answer is: 159
Good luck on your assignment & enjoy your day!

Answer:
10² + (3 + 5)² - 5 = 159
Step-by-step explanation:
Given expression,
→ 10² + (3 + 5)² - 5
Evaluating the expression,
→ 10² + (3 + 5)² - 5
→ 10² + 8² - 5
→ 100 + 64 - 5
→ 100 + 59
→ 159
Hence, the answer is 159.

How many squares u can actually count in this given picture?
Answer:
I counted 24.
Step-by-step explanation:
Its probably a trick question though
Answer: I counted 36.
(edit) But the answer is 40.
Step-by-step explanation:
Count all the "normal" squares. 16.
Then all the 2x2 normal squares. 9.
Then count all the tiny squares. 8.
Then the 2 big squares the tiny squares make. 2.
Then the giant square, which is all the squares. 1.
And I agree this probably is a trick question.
16 + 9 + 8 + 2 + 1 = 36 squares in total
*EDIT*
Apparently 3x3 squares exist so...
3x3 squares . 4
so 36 + 4 = 40 squares in total
(thanks to the person who asked the question in the first place for telling me about those 3x3 squares)

Ethan is randomly choosing a letter from the word “SKIP” and rolling a standard 6-sided die.
Calculate the following:
P (consonant, even number) =
Give your answer as a decimal.
(Hint: A consonant is any letter besides (a, e, I, o, u)
=====================================================
Work Shown:
A = P(consonant)
A = 3/4 since there are 3 consonants out of 4 letters in the word "SKIP".
B = P(even number)
B = 3/6
B = 1/2
P(consonant, even number) = A*B
P(consonant, even number) = (3/4)*(1/2)
P(consonant, even number) = 3/8
P(consonant, even number) = 0.375
eight multiply by 5 over 12 equals
Hi! I hope you're enjoying your day!
First, 8 multiplied by 5 is equal to 40.
Then, 40 over 12 is the same as 40 divided by 12.
But hey! 40 isn't divisible by 12.
So we write this as a fraction:
[tex]\bold{\displaystyle\frac{40}{12} }[/tex]
Surprise! This fraction can be reduced.
Divide both the numerator (40) and the denominator (12) by 4:[tex]\bold{\displaystyle\frac{10}{3} }[/tex]
Hence, the answer is:
[tex]\boxed{\boxed{\bold{\displaystyle\frac{10}{3} }}}[/tex] <-- the answer written as an improper fraction
[tex]\boxed{\boxed{\bold{3\displaystyle\frac{1}{3}}}}[/tex] <-- the answer written as a mixed number
Hope everything is clear.

whats (x-3/4)^2 - 5 = 4 using the square root property?
please have an explanation; will give brainliest
answer: -9/4 and 15/4
Answer:
x = {-9/4, 15/4}
Step-by-step explanation:
To use the square root property to solve the quadratic, you need to get it to a form where the square root function can be usefully applied. That will mean having a square of a binomial on one side of the equal sign, and a constant on the other side of the equal sign.
We can get that from the given equation by adding 5 to both sides.
(x -3/4)^2 -5 = 4 . . . . . . given
(x -3/4)^2 = 9 . . . . . . . add 5 to get the square by itself
x -3/4 = ±3 . . . . . . . . . take the square root
x = ±3 +3/4 = {-9/4, 15/4} . . . . add 3/4 and expand the result

solve the inequality |x+6-|3x+6||+|x+2|-x-4 less then or equal to 0
It looks like the inequality is
[tex]\bigg|x + 6 - |3x + 6|\bigg| + |x + 2| - x - 4 \le 0[/tex]
or equivalently,
[tex]\bigg|x + 6 - 3 |x + 2|\bigg| + |x + 2| - x - 4 \le 0[/tex]
Recall the definition of absolute value:
[tex]|x| = \begin{cases} x & \text{if } x \ge 0 \\ -x & \text{if } x < 0 \end{cases}[/tex]
By this definition, we have
[tex]|x + 2| = \begin{cases} x + 2 & \text{if } x + 2 \ge 0 \\ -(x + 2) & \text{if } x + 2 < 0 \end{cases} = \begin{cases} x + 2 & \text{if } x \ge -2 \\ -x - 2 & \text{if } x < -2 \end{cases}[/tex]
Suppose [tex]x < -2[/tex]. Then
[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |x + 6 - 3 (-x - 2)| + (-x - 2) - x - 4 \\\\ = |4x + 12| - 2x - 6[/tex]
By definition of absolute value,
[tex]|4x + 12| = 4 |x + 3| = \begin{cases} 4x + 12 & \text{if } x \ge -3 \\ -4x - 12 & \text{if } x < -3 \end{cases}[/tex]
so we further suppose that [tex]x < -3[/tex]. Then
[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |4x + 12| - 2x - 6 \\\\ = (-4x - 12) - 2x - 6 \\\\ = -6x - 18 \le 0 \\\\ \implies x \ge -3[/tex]
but this is a contradiction, so this case gives no solution.
If instead we have [tex]-3 \le x < -2[/tex], then
[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |4x + 12| - 2x - 6 \\\\ = (4x + 12) - 2x - 6 \\\\ = 2x + 6 \le 0 \\\\ \implies x \le -3[/tex]
and [tex]-3 \le x[/tex] and [tex]x \le -3[/tex] means that [tex]\boxed{x = -3}[/tex].
Now suppose [tex]x \ge -2[/tex]. Then
[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |x + 6 - 3 (x + 2)| + (x + 2) - x - 4 \\\\ = |-2x| - 2 \\\\ = 2 |x| - 2[/tex]
If we further suppose that [tex]-2 \le x < 0[/tex], then
[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = 2 |x| - 2 \\\\ = -2x - 2 \le 0 \\\\ \implies x \ge -1[/tex]
Otherwise, if [tex]x \ge 0[/tex], then
[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = 2 |x| - 2 \\\\ = 2x - 2 \le 0 \\\\ \implies x \le 1[/tex]
Taken together, this case gives the solution [tex]\boxed{-1 \le x \le 1}[/tex]
So, the overall solution to the inequality is the set
[tex]\boxed{\left\{ x \in \mathbb R : x = -3 \text{ or } -1 \le x \le -1 \right\}}[/tex]

Step-by-step explanation:
At the y-intercept the value of y is equal to 0.
=> 0 = x² + 5x + 9
=> x = -5 ± √25 - 4(9) / 2
=> x = 5 ± √-11 / 2
