Step-by-step explanation:
Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Sula designs greeting cards for her friends. Each friend has a 30% chance to get a musical greeting card. Design a simulation that can be used to estimate the probability that a friend will receive a musical greeting card.
Answers
Here's a simple Python code that simulates the process:
```python
import random
num_friends = 1000 # the number of friends
num_musical_cards = 0 # the number of friends who received musical cards
# simulate the card distribution for each friend
for friend in range(num_friends):
if random.random() < 0.3:
num_musical_cards += 1
# calculate the probability of a friend receiving a musical card
prob = num_musical_cards / num_friends
print("Probability of a friend receiving a musical card:", prob)
```
In this simulation, we create a loop that simulates the card distribution for each friend. We randomly assign a musical card to each friend with a 30% chance. Then, we calculate the probability of a friend receiving a musical card by dividing the number of friends who received musical cards by the total number of friends.
You can adjust the `num_friends` and `random.random() < 0.3` parameters to match your specific scenario.

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

Malik collects rare stamps and has a total of 96 stamps. He has 24 more domestic stamps than foreign stamps. Let d represent the number of domestic stamps and let f represent the number of foreign stamps.
This system of equations models the given information for both stamp types.
d – f = 24
d + f = 96
Solve the system of equations.
How many foreign stamps does Malik have?
number of foreign stamps
How many domestic stamps does Malik have?
number of domestic stamps
Answers
Answer:
Domestic Stamps: 60
Foreign Stamps: 36
Step-by-step explanation:
96 - 24 = 72
72 ÷ 2 = 36
36 + 24 = 60
d - f = 24
60 - 36 = 24
24 = 24
d + f = 96
60 + 36 = 96
96 = 96
There are 60 domestic stamps and 36 foreign stamps.
Use the elimination method to solve
d-f=24
-d+f=96
_______
Line them up and them subtract
-2f=-72
The d cancel out
Isolate f by dividing both sides by -2
f=36
Replace f with 36 in either equation and then solves
d-(36)=24
Isolate d by adding both sides by 36
d=60

Which statement is true about milliliters and kiloliters?
a. There are 1,000,000 milliliters in a kiloliter.
b. There are 1,000,000 kiloliters in a milliliter.
c. There are 1,000 milliliters in a kiloliter.
d. There are 1,000 milliliters in a kiloliter.
Answers
The correct statement is a. There are 1,000,000 milliliters in a kiloliter.
A kiloliter is a unit of volume equal to 1,000 liters. One liter is equal to 1,000 milliliters. Therefore, one kiloliter is equal to 1,000 x 1,000 = 1,000,000 milliliters.
solve for t
7t–8=10+2t
Answers
Answer:
t=18/5
Step-by-step explanation:
7t-8=10+2t
+8 on both sides
7t-8+8=10+2t+8
combine like terms
7t=18+2t
-2t on both sides
7t-2t=18t+2t-2t
combine like terms
5t=18
divide by 5
5t/5=18/5
t=18/5
7t=18+2t
Subtract 2t from both sides:
5t=18
Divide both sides by 5:
t=18/5
t=3.6
