The change in altitude for all 6 balloons for 5 minutes = 6 × 1300 = 7800 feet
Step-by-step explanation:
Step 1 :
Number of balloons = 6
Height descended per minute = 260 feet
Total time of descent = 5 minutes
We need to determine the total change in altitude for all the 6 balloons
Step 2 :
The change in altitude for 1 balloon for 1 minute = 260 feet
The change in altitude for 1 balloon for 5 minutes = 5 × 260 = 1300 feet
Therefore
the change in altitude for all 6 balloons for 5 minutes = 6 × 1300 = 7800 feet
Step 3 :
Answer :
The change in altitude for all 6 balloons for 5 minutes = 6 × 1300 = 7800 feet
Rick's score is higher than 91% of the other students.
Given that on a placement examination, Rick scored lower than 1192 of the 12,790 students who took the exam, to find the percentile, rounded to the nearest percent, for Rick's score, the following calculation must be performed:
- 12790 - 1192 = 11598
- 12790 = 100
- 11598 = X
- 11598 x 100/12790 = X
- 1159800/12790 = X
- 90.68 = X
Therefore, Rick's score is higher than 91% of the other students.

Let's find the difference between every two numbers. Let's start with 12,500 and -2500. We know this is a multiplication or division problem because of every other number being negative.
-2500/12,500=-0.2; let's see if the product to -2500 and -0.2 is 500. -0.2×-2500=500 500×-0.2=-100; since you only have to multiply the previous number by -.2, let's find the next two numbers.
-100×-0.2=20 20×-0.2=-4
So, the next two numbers in the pattern are 20 and -4.
Answer:
for the perimeter to be made into a equation it would take the equation
2(3x - 5) + 2(2x + 1)
And for the perimeter to equal 42 x would have to equal 5
Step-by-step explanation:
so first of all we have to find our equation to equal 42:
2(3x - 5) + 2(2x + 1) = 42
you then multiply 2 for both parentheses:
(3x * 2) + (-5 * 2) + (2x * 2) + (1 * 2) = 42
so its now:
6x -10 + 4x + 2 = 42
now your going to add variables to variables and numbers to numbers:
(6x + 4x) + ( -10 + 2) = 42
to get:
10x + (-8) = 42
Now your going to add 8 to both sides:
10x + (-8) = 42
+8 +8
Giving the equation:
10x = 50
now you divide both sides by 10 to get:
10x/ 10 = 50/10
x = 5
to solve you put 5 in place of the variable x:
2(3*5 - 5) + 2(2*5 + 1)
2(15 - 5) + 2(10 + 1)
20 + 22 = 42
So x equals 5 if the perimeter equaled 42
