Absolute value of 7. Any real numbers in the absolute sign would equal to the positive value.
Definition
[tex] \large \boxed{ |x| = \begin{cases} x \: \: \: \: (x \geqslant 0) \\ - x \: \: \: \: (x < 0) \end{cases}}[/tex]
If we substitute x = 7 in. Answer by using the definition of absolute value. Note that we only substitute x = 7 in x and not -x since 7 is greater than 0 and not less than 0.
[tex] \large{ |7| = 7 \: \: \: \: (x \geqslant 0)}[/tex]
You may also be wondering what will happen if we substitute x = any negative numbers.
[tex] \large{ | - 7| = - ( - 7) \: \: \: \: (x < 0)} \\ \large \boxed{ | - 7| = 7}[/tex]
Because -7 is less than 0. We substitute in -x and not x. This is the definition of absolute value. But to understand it easily, any numbers in absolute value have to equal to their positive value.
Conclusion
|7| means the absolute value of 7.|7| is 7.|x| is x when x ≥ 0 but -x when x < 0Let me know if you have any doubts regarding the absolute value through comment!

Answer:
the new value is 17 and the absolute change is -3
Step-by-step explanation:
take 20 and subtract your percentage increase
20 - (15% × 20) =
20 - 15% × 20 =
(1 - 15%) × 20 =
(100% - 15%) × 20 =
85% × 20 =
85 ÷ 100 × 20 =
85 × 20 ÷ 100 =
1,700 ÷ 100 =
A fish-tank has a length of 27 centimeters, a width of 21 centimeters and a depth of 16 centimeters. Find the volume of the fish-tank.
Answer:
To find the volume of the fish tank, we will need to multiply the height, the length, and the width of the fish tank. So, 21 x 27 x 16 = 9072 cm
Answer:
9027 cm^3
Step-by-step explanation:
V= L*W*H
V=27cm*21cm*16cm
V=567*16
V=9072 cm^3
The cm is cubed because you are also multiplying cm*cm*cm So, it would be cm cubed or cm^3
What's The actual length of QR (round to 3 decimal places) ?
Answer:
4.383
Step-by-step explanation:
Pythagoras
a² + b² = c²
with c being the baseline of the rectangular triangle (the line opposite to the 90 degree angle).
so, in our example here c=6.5cm, a=QR, b=4.8cm
a² = c² - b² = 6.5² - 4.8² = 19.21
a = sqrt(19.21) = 4.383

Miss Chambers bought 5 pens for $255, if she made a profit of $3 each per pen how much did she sell a pen for?
Answer:
$54
Step-by-step explanation:
First, we calculate the amount she paid for each pen.
$255/5 = $51
She paid $51 for each pen.
She made a profit of $3 per pen, so she sold each pen for $51 + $3 = $54
Answer: $54

round to the nearest whole number than add 4.208 + 2.482
4.208 + 2.482= 6.69 so rounding that would be 7
4.208 + 2.482 = 6.69
When we round it to the nearest, it becomes 7.

Your purchase a T-shirt with a label pre-tax price of $17 the local sale price rate is 5% what is your final cost including tax
Answer: $17.85
Step-by-step explanation:
The tax on the T-shirt is 5% and the price is $17.
To find the after-tax cost, first find the tax amount:
= 5% * 17
= $0.85
Then add this tax amount to the price to find the after-tax amount:
= 17 + 0.85
= $17.85

Determine the equation of the line that passes through (5,2)and has the same y-intercept as y = 3
Answer:
y = -0.2(x) + 3
Step-by-step explanation:
One way to find an equation for a line is to find two points and go from there. To find the second point, we can note that the y intercept means when x=0. In the line y=3, y is always 3, so when x=0, y = 3.
Our two points are then (5, 2) and (0,3)
To find the slope, we can use
[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{3-2}{0-5} \\= \frac{1}{-5} \\= -0.2[/tex]
Using the formula y = mx + b and the slope m = -0.2, plugging into (5, 2) and solving for b, we get
2 = -0.2 (5) +b
2 = -1 + b
add 1 to both sides to isolate the b
b = 3
Our formula is thus
y = -0.2(x) + 3

Does anybody know it part 2
Answer:
x = 33
Step-by-step explanation:
(x + 13) + (4x + 2) = 180
x + 13 + 4x + 2 = 180
5x + 15 = 180
5x = 180 - 15
5x = 165
x = 165/5
x = 33
Check:
(x + 13) + (4x + 2) = 180
(33 + 13) + 4(33) + 2 = 180
46 + 132 + 2 = 180
46 + 134 = 180

Find the value of x.
Answer:
Step-by-step explanation:
Vertically opposite angles are equal
8x + 2 = 7x + 11
Subtract 2 from both sides
8x = 7x + 11 - 2
8x = 7x + 9
Subtract 7x from both sides
8x - 7x = 9
x = 9

what is the probability of picking the most expensive car from a range of 6 new cars
The solution is: 16.67% is the probability of picking the most expensive car from a range of 6 new cars.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Here, we have,
given that,
the most expensive car from a range of 6 new cars.
so, total sample space = 6
the number of favorable outcome = 1
so, probability = 1/6
Now, the word “expensive” was used to confuse you but simply put, the probability of getting “the most expensive car” is 1/6.
It is 1/6 because there is nothing that heightens its chances of being picked over the other cars,
hence the probability of any car will be equal to that of the “most expensive car”.
And for a percentage:
(1/6) x (100) = 16.67%
Hence, The solution is: 16.67% is the probability of picking the most expensive car from a range of 6 new cars.
