Answer:
Number of donuts each student get = 144 / x
Step-by-step explanation:
Given:
Number of donuts = 12 dozen
Number of students = x
Find:
How many donuts each student get
Computation:
Total number of donuts = 12 × 12 = 144
Number of donuts each student get = Total number of donuts / Number of students
Number of donuts each student get = 144 / x
A DVD that originally cost $30 is on sale for 10 percent off. Complete the steps to solve the problem.
Answer:
$27
Step-by-step explanation:
10% of 30 = 3, so if we take 3 or 10% away from 30, you will get 27.
Answer:
27$
Step-by-step explanation:
0% of 30 = 3, so if we take 3 or 10% away from 30, you will get 27.
If we decrease the time it takes for a car to travel over the same distance, this will (2 points) increase the speed have no effect on velocity or speed decrease the speed decrease the velocity
Answer:
Increase the speed
Step-by-step explanation:
The only way to decrease the time it would take to travel over a distance would be to increase the speed.
Answer:
see below
Step-by-step explanation:
if time decreases.... the velocity will decrease.
ex.
d = v/t
100 m = v/10 sec v = 1000 m/s
100 m = v/5 sec v = 500 m/s
100 m = v/1 sec v = 100 m/s
therefore,
if we decrease the time it takes for a car to travel over the same distance,
the velocity decreases too.

|-9-7x|=|23-7x|.
Graph the solutions, if possible.
Answer: No Solution
Step-by-step explanation:
When there are absolute values on both sides, you simply just get rid off the signs. (Normally, it results in positive and negative on the other side)
SOLVE:
Given
|-9-7x|=|23-7x|
No absolute value sign
-9-7x=23-7x
Add 7x on both sides
-9=23
ANSWER:
This is no solution, because -9≠23
if PQ=8 and Q lies at -13 where could P be located?
Answer:
In the given figure the point on segment PQ is twice as from P as from Q is. What is the point? Ans is (2,1).
Step-by-step explanation:
There is really no need to use any quadratics or roots.
( Consider the same problem on the plain number line first. )
How do you find the number between 2 and 5 which is twice as far from 2 as from 5?
You take their difference, which is 3. Now splitting this distance by ratio 2:1 means the first distance is two thirds, the second is one third, so we get
4=2+23(5−2)
It works completely the same with geometric points (using vector operations), just linear interpolation: Call the result R, then
R=P+23(Q−P)
so in your case we get
R=(0,−1)+23(3,3)=(2,1)
Why does this work for 2D-distances as well, even if there seem to be roots involved? Because vector length behaves linearly after all! (meaning |t⋅a⃗ |=t|a⃗ | for any positive scalar t)
Edit: We'll try to divide a distance s into parts a and b such that a is twice as long as b. So it's a=2b and we get
s=a+b=2b+b=3b
⇔b=13s⇒a=23s

what is 210 divided by 2 1/2
Answer:
210 divided 2 1/2= 84....
The 210 divided by 2 1/2 is 84.
To calculate 210 divided by 2 1/2, first, we need to convert the mixed number 2 1/2 to an improper fraction. The improper fraction for 2 1/2 is (2 * 2 + 1) / 2 = 5/2.
Now, we can perform the division:
210 ÷ 5/2
To divide by a fraction, we multiply by its reciprocal:
210 * 2/5
Now, perform the multiplication:
(210 * 2) / 5 = 420 / 5
Next, simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 5:
420 ÷ 5 = 84
The result of 210 divided by 2 1/2 is 84. So, 210 ÷ 2 1/2 = 84.

Two landscaping companies made bids on the landscaping of a new apartment complex. Company A bid $595,000 for materials and plants and $204,000 for labor. Company B bid $660,000 for materials and plants and $136,000 for labor. How much lower was the bid made by Company B?
Answer:
$3,000
Step-by-step explanation:
Company A bid $595,000 for materials and plants and $204,000 for labor.
Total = $595,000 + $204,000 = $799,000Company B bid $660,000 for materials and plants and $136,000 for labor.
Total = $660,000 + $136,000 = $796,000The difference:
$799,000 - $796,000 = $3,000
