B. part=160%•40
C. 40=160%•whole
Answer:
part = 160% *40

oliver tries to cut a piece of metal 30 centimeters long the metal ends up being 29.4 centimeters long what is the percent error in this situation? , please tell me how you got the answer. Will give brainliest
Answer:
I'd say its 1.02% but don't quote me on that
Step-by-step explanation:
The percent error in the given situation is 2%. Therefore, option C is the correct answer.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Oliver tries to cut a piece of metal 30 centimeters long the metal ends up being 29.4 centimeters long.
Difference in number =30-29.4
= 0.6
Now, percent error = 0.6/29.4 ×100
= 2.04%
≈ 2%
The percent error in the given situation is 2%. Therefore, option C is the correct answer.

The shaded area on the grid represents the part of a rectangular wall that was painted. Each small square on the wall has the same dimensions. What percentage of the wall was painted?
Answer:
68
Step-by-step explanation:
There are total of 5*5 = 25 rectangles on the wall. 17 of these are painted.
17 / 25 = 17*4 / 100
17 * 4 = 68
Answer 68%
Step-by-step explanation:
The measure of Angle D is
degrees.
O=41 degrees
Answer:
49°
Step-by-step explanation:
O=41° and G=90° (because it is a right angle). The sum of the interior angles of a triangle is 180°. So, add the known angles, 41°+90°=131°. Since the sum of all three angles needs to be 180°, subtract the known angles from the total, 180°-131°=49°, to find the unknown angle.
The angle D in triangle OGD measures 49 degrees.
To find the measure of angle D in triangle OGD, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
Given that angle O is 41 degrees and angle G is 90 degrees, we can substitute these values into the equation:
Angle O + Angle G + Angle D = 180
41 + 90 + Angle D = 180
131 + Angle D = 180
Now, we can solve for angle D by subtracting 131 from both sides:
Angle D = 180 - 131
Angle D = 49
Therefore, angle D in triangle OGD measures 49 degrees.

Determine the correct value of 3x + 2 when x = 5. Show your work
Answer:
17
Step-by-step explanation:
3 multiply by 5 (which is x) = 15+2
The value of function 3x + 2 at x = 5 will be 17.
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The function is,
⇒ 3x + 2
And, The value of x = 5
Now,
The value of the function 3x + 2 at x = 5 is find as;
The function is,
⇒ 3x + 2
Substitute x = 5 in above equation as;
⇒ 3x + 2
⇒ 3 × 5 + 2
⇒ 15 + 2

Find the slope of a line with this information, "−12; (4,−5)". Write your answer in slope intercept form.
Answer:
y = -12x - 43
Step-by-step explanation:
"slope-intercept form" looks like y = mx + b.
We are given m = -12 and a point on the line which is (4, -5).
Substituting 4 for x, -5 for y and -12 for m, we get:
-5 = -12(4) + b. Then b = -43, and the desired equation is y = -12x - 43.
