Answer:
just do the step by step and you'll probably get it because it's quite simple but hard for me to explain so just read this!
Step-by-step explanation:
In making any measurement, the chances are that our results will not be absolutely accurate. We can often compare our results with some standard or accepted value to see how closely they agree. But how much error can be allowed before the result becomes meaningless?
As you may guess, the amount of error that is acceptable varies with the situation. Suppose you measure the distance on a map between your Scarsdale and Mamaroneck and you get a result of 5 miles. If the actual distance is 5 1/2 miles, the chances are this error will have no effect on the trip between the two towns. But if the same degree of error existed in the calculations used to send astronauts to the moon, those people would be in big trouble!
Percentage Error = measured value - accepted value x 100%
accepted value
Suppose, you measured the length of a table and obtained a measurement of 202 cm. A friend also measures the table and obtains a result of 198 cm. To calculate the percentage error in each of the measurements, you need to know the "correct' or “accepted value” of the length of the table. After consulting the manufacturer’s catalog, you find that the table's length is listed as 200 cm in length. This will be used as the accepted value in our calculation.
The calculations of percentage error for the two measurements are shown below. Both measurements show an error of 1%. Your friend has made a measurement which is on the low side of the accepted value and is therefore, negative. You, on the other hand, have made an error on the high side of the accepted value and it is positive.
I dont know the answer but I hope this helped!

Answer:
B.) , ratio of 20:1C.) , There are 11 costumers per tower and 11000 costumers in totalStep-by-step explanation:
Please mark brainliest...
multiply each value of the C. by 1,000 to get the # of C.s divide the # of C.s / T.s this gives you C.s per T.Convert to ratio formatthere is on average 15 to 20 C.s per T.5250/273 = 14.0756250/325 = 19.2307250/377 = 19.2309250/273 = 19.230 6250 = y377 572
2. multiply both sides by 572
3. 572 . 6250 = y
377
4. divide known pair
572 x 19.230 = y
5. solve for y
6. y = 10999.56
7. divide y value by 1000
8. 10.99956
9. round to the nearest whole #
10. There are 11 costumers per tower and 11000 costumers in total

The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle

Find the area of the region bounded by the line y=3x-6 and line y=-2x+8. For each of the given situations, find the AREA of the bounded region, the answer is not A, B, C, or D, I need to solve the answer for that case. (For example, C, it says the line y=6. I need you to find the area of the bounded region when the line y is 6 and intersects the 2 other lines.)
A: the x-axis.
B: the y-axis.
C: the line y=6
D: the line x=5.

Answer:
21!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
18
Step-by-step explanation:
It would be 18 because you would do -3+21 which would be equal to 18. You would do this because you are first at -3 but then at 11 the temperature increased 21.

Write the equation.
Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
c - 23.24 = 24.76
c + 23.24 = 24.76
c - 24.76 = 23.24
c + 24.76 = 23.24
21.
Solve it.
Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
5 cookies
1.5 cookies
50 cookies
48 cookies
Answer:
just do this 24.76min. 23.24 then see what u have got for
Answer:
c - 23.24 = 24.76 (the first option)
48 cookies
Explanation:
Profit is equal to revenue(amount made) minus costs, or r - cost = p. The revenue is 1*cookies sold, or c. So, c - 23.24 = 24.76.
Solving is relatively simple,
c - 23.24 = 24.76
c = 48 (add 23.34 to both sides)

-4p + 23 = 15
Show your work
Answer:
p=2
Step-by-step explanation:
Isolate the variable
-4p = -8
Divide by the coefficient
p = 2
Answer:
p = 2
Step-by-step explanation:
-4p +23 = 15
-4p + 23 - 23= 15 - 23
-4p = -8
-4p/-4 = -8/-4
p = 2
