the art museum charges $13 for each adult admission and $8 for each child the total bill for the 182 people from a achool trip was $1606 how many adults and children went to the museum?
Answer:
152 kids and 30 adults
Step-by-step explanation:
To solve this, we must create a system of equations
Suppose:
x = the number of adults
y = the number of children
We know that a total of 182 people attended the trip.
So:
x + y = 182
This equation represents the number of people attending the trip.
To find out the cost, look at the problem.
It costs 13$ for one adult and 8$ for a child.
So:
13x + 8y = 1606
This equation represents the total cost to attend the museum. Now, we must solve.
[There are two ways to solve a system of equations, substitution and adding/subtracting. I will use adding and subtracting. The steps to solving the system of equations is in the photos below]
The final answer is 152 kids and 30 adults

I know the answer but I need to understand HOW to get it. Bailey will roll a number cube and flip a coin for a probability experiment. The faces of the cube are labeled 1-6. The coin can land on heads or tails.If Bailey rolls the number cube once and flips the coin once which list contains only the outcomes in which the number cube lands on a number greater than 4.
The right answer was a list with says:
5, Heads
5, Tails
6, Heads
6, Tails
Answer:
Total output= H5, H6,T5, T6
Step-by-step explanation:
Bailey will roll a number cube and flip a coin for a probability experiment.
The faces of the cube are labeled 1-6= 6 possible outcomes
The coin can land on heads or tails= 2 possible outcomes
If Bailey rolls the number cube once= 1 output
and flips the coin once = 1 output
Total output will be combined outcome of cube and coin:
possible outcome of cube= 1, 2, 3 , 4 , 5, 6
possible outcome of coin= H, T
(H for heads and T for tails)
Total output =possible combined outcome of cube and coin= H1, H2, H3 , H4 , H5, H6, T1, T2, T3 , T4 , T5, T6
Now
the outcomes in which the number cube lands on a number greater than :
reduces the total required output by removing the combination when the number cube lands on a number less than or equals to 4
therefore removing H1, H2, H3 , H4 and T1, T2, T3 , T4 from the total outcome will result in following list:
Total output= H5, H6,T5, T6 i.e.
5, Heads
5, Tails
6, Heads
6, Tails !

Footware manufacturing is projected to decrease output by 8.4% from 2006 to 2016. If footware manufacturing had 1.8 billion dollars of output in 2006, approximately how much output is expected in 2016?
Answer:
The output expected in 2016 is 1.6488 x 10 ^9 or 1.6488 billion
Step-by-step explanation:
The output is decreased by 8.4% from 2006 to 2016.
Amount of output in 2006 = 1.8 billion dollars
Decrease in output = 8.4%
We need to find the 8.4% of 1.8 billion dollars and then subtract the result from 1 billion dollars.
We know 1.8 billion = 1,800,000,000 or 1.8 x 10^9
8.4% of 1.8 billion = 8.4/100 * (1.8 x 10^9)
= 151200000
So, Output expected in 2016 = 1.8 x 10^9 - 151200000
= 1648800000 or 1.6488 x 10 ^9
So, the output expected in 2016 is 1.6488 x 10 ^9 or 1.6488 billion.

Step-by-step explanation:
Step 1: Combine like terms
11x + 5 = 180
Step 2: Subtract 5 from both sides.
11x = 175
Step 3: Divide 11 from both sides
x = 175/11

Teach me how to yeet
Answer:
d
Step-by-step explanation:
I'm thinking the last one
While 'yeet' is not an academically defined term, it typically refers to the act of throwing something with force. Drawing from a story on LibreTexts, one can learn the technique for effectively throwing objects such as a horseshoe, which involves grip, stance, focus on the target, and a smooth release.
To throw a horseshoe effectively, similar to learning how to "yeet," one must:
Hold the horseshoe in a comfortable but firm grip with your thumb along one of the sides of the horseshoe.
Stand at the designated throwing line and focus on the stake you're aiming at.
Swing your arm forward smoothly and release the horseshoe when your hand is about waist-high, keeping your eyes on the target for accuracy.
it takes 91 kiloliters of water to fill the hendersons swimming pool. how much is this in liters
Answer:
91,000 Liters
Step-by-step explanation:
1 Kiloliters = 1,000 liters
91 times 1,000 = 91,000
To convert 91 kiloliters to liters, multiply 91 by 1,000, which equals 91,000 liters. Therefore, 91 kiloliters of water is equal to 91,000 liters.
To convert kiloliters to liters, you need to know the conversion factor. 1 kiloliter (kL) is equivalent to 1,000 liters (L). Therefore, to convert 91 kiloliters to liters, you simply multiply 91 by 1,000.
The calculation would be as follows:
91 kL × 1,000 L/kL = 91,000 L
So, 91 kiloliters of water is the same as 91,000 liters of water.

Fran solved the equation 42 = x + 23. Although her final answer was correct, she could have found it in a simpler way. Which sentence best explains why?
The easier way to solve the equation 42 = x + 23 is by subtracting 23 from both sides of the equation. This will result in the value of x being 19. The process of isolating the variable on one side of the equation is important for finding the value of the variable.
Explanation:In this mathematical equation, 42 = x + 23, to find the value of x, we need to isolate x on one side of the equation. The operation involved is subtraction. We subtract 23 from both sides of the equation. This process is important to maintain the equality of the equation. By doing this operation, both sides of the equation still balance. After subtracting 23 from both sides, we get x = 42 - 23, resulting in x = 19.
In order to find the value of x, Fran needs to isolate it on one side of the equation. To do this, she can subtract 23 from both sides of the equation, resulting in 42 - 23 = x. Simplifying further, she finds that x = 19.
Alternatively, Fran could have recognized that 42 - 23 equals 19 and immediately concluded that x = 19, saving her the need to do the subtraction step.
Therefore, the sentence that best explains why Fran could have found the answer in a simpler way is that she could have recognized the subtraction step as an immediate result and skipped it.
