500-250= 250
there for its half off 50% because its split down the middle, so thats an easy one
if 125% of a number is 750 what is 65% of the number
Answer:600
Step-by-step explanation:
We have, 125% * x = 750
Multiplying both sides by 100 and dividing both sides by 125
we have x = 750 * 100/125
you then get X=600
Answer:x=600
Step-by-step explanation: Multiplying both sides by 100 and dividing both sides by 125

there are ten birdbaths in a park. on the first day of spring, the birdbaths are filled. Several weeks later, the overall change in the water level is found. the results are shown in the table. what is the range of the data?
Based on the change in the water levels of the ten birdbaths in the park, the range of the data is 4.2.
How to find range?To find the range of a distribution of numbers, you need to subtract the smallest number from the largest number.
The largest number in the distribution of birdbaths is 2.6 and the smallest number in the distribution is -1.6
The range is therefore:
= 2.6 - (-1.6)
= 2.6 + 1.6
= 4.2
The range of numbers are:
2.2, 0.3, -1.5, 2.6, 1.9, 0.4, 0.6, -1.6, 2.5, -0.6

The value of x for which the numerical length of SP is equal to PT is 1/2.
What is Number line?Number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.
Given are the coordinates of three points S,T and P on number line. Also the numerical length of SP is equal to PT. From the question, we can write -
→ Point S at 0.
→ Point T at 1.
→ Point P at x.
It is given that -
SP = PT
Distance between S and P = Distance between P and T.
x - 0 = 1 - x
2x = 1
x = 1/2
Therefore, the value of x for which the numerical length of SP is equal to PT is 1/2.

A delivery person has two different delivery routes that he follows the first route is 20.75 miles long and the second is 30.25 miles long he travels each route 4 times a week after 7 weeks how many total miles has he traveled
Answer:
Step-by-step explanation:
20.75 miles x 4 = 83 miles
30.25 miles x 4 = 121 miles
Now take the 83 and multiply by 7 for the 7 weeks and multiply the 121 also by 7.
83 x 7 = 581
121 x 7 = 847
Now add the 581 miles with the 847 to get the total miles travelled.
581+847 = 1428 Miles
Answer: The delivery person travels 1428 miles
find the general form of the quadratic function with the vertex (1,4) and a point on the graph (-3,20)
The general form of the quadratic function is x² - 2 · x - y + 5 = 0.
How to find the general form of the quadratic function
In this question we must derive the equation of the parabola in vertex form, whose description is shown below:
4 · p · (y - k) = (x - h)² (1)
Where:
(h, k) - Coordinates of the vertex.(x, y) - Coordinates of a point of the parabola.p - Distance from vertex to focus.If we know that (h, k) = (1, 4) and (x, y) = (- 3, 20), then the distance from vertex to focus is:
p = (x - h) / [4 · (y - k)]
p = (- 3 - 1)² / [4 · (20 - 4)]
p = (- 4)² / 64
p = 16 / 64
p = 1 / 4
Then, the equation of the parabola in vertex form is y - 4 = (x - 1)². And now we find the general form of the quadratic formula, that is:
A · x² + B · x + C · y + D = 0 (2)
Then, we proceed to obtain the general form:
y - 4 = (x - 1)²
y - 4 = x² - 2 · x + 1
x² - 2 · x - y + 5 = 0
The general form of the quadratic function is x² - 2 · x - y + 5 = 0.

If Ð1 and Ð2 are complementary angles, and mÐ1 = 74!; "nd mÐ2.
Answer:
∠ D2 = 16°
Step-by-step explanation:
complementary angles sum to 90° , then
∠ D1 + ∠ D2 = 90°
74° + ∠ D2 = 90° ( subtract 74° from both sides )
∠ D2 = 16°
If two angles are complementary they add up to a total of 90 degrees.
So we know that
D1+D2=90, because the problem tells us they're complementary
Now, we know as well that D1 = 74, so we can plug it into the little equation and solve in terms of D2.
[tex]D1+D2=90[/tex]
[tex]74+D2=90[/tex]
