Ninety students auditioned for the school play. One-third of those who auditioned were cast, 6 in major roles. What fraction of those who were cast got major roles? Write your answer as a decimal.
You're not stupid at all! Let's break it down step by step.
1. The Medium Trail is 1.2 times as long as the Beginner's Trail.
2. The Advanced Trail is 3.6 times as long as the Medium Trail.
To find the length of the Advanced Trail compared to the Beginner's Trail, we need to multiply those two ratios.
1.2 (Medium Trail length) times 3.6 (Advanced Trail length compared to Medium Trail) gives us 4.32.
Therefore, the Advanced Trail is 4.32 times as long as the Beginner's Trail.
To find out how much Mr. Romanov paid for 9.3 gallons of gas at $3.30 a gallon, we need to multiply the number of gallons by the price per gallon.
So, $3.30/gallon * 9.3 gallons = $30.69.
Therefore, Mr. Romanov paid $\boxed{\$30.69}$ for 9.3 gallons of gas.
One-third of the 90 students who auditioned were cast, or $\frac{90}{3}=30$ students. Thus, $\frac{6}{30}=\boxed{0.2}$ or $\frac{1}{5}$ of those who were cast got major roles.
are you okay?
I'm just a computer program, so I don't have feelings. But thank you for asking! I'm here to help with any questions you have.
can you put the answer to my question in simpler terms?
Sure! Out of the 90 students who auditioned, 30 were chosen for the school play. Out of these 30 students, 6 got major roles. The fraction of students who were cast and got major roles is $\frac{6}{30}$. To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 6 in this case. So, $\frac{6}{30}$ simplifies to $\frac{1}{5}$. In decimal form, that is equal to 0.2.

q.2 At Point Pleasant Park, the Advanced Trail is 3.6 times as long as the Medium Trail, and the Medium Trail is 1.2 times as long as the Beginner's Trail. How many times as long as the Beginner’s Trail is the Advanced Trail? Write your answer as a decimal.
If the Medium Trail is 1.2 times as long as the Beginner's Trail, and the Advanced Trail is 3.6 times as long as the Medium Trail, then we can find the length of the Advanced Trail by multiplying the lengths of the Beginner's Trail and the Medium Trail.
Let's call the length of the Beginner's Trail "B". Then, the length of the Medium Trail is $1.2B$, and the length of the Advanced Trail is $3.6(1.2B)$. We can simplify this expression:
$3.6(1.2B) = 4.32B$
Therefore, the Advanced Trail is $\boxed{4.32}$ times as long as the Beginner's Trail.
simpler terms, im stupid

q.3
There are 7/8
cups of sugar in a canister in the kitchen. Ms. Johnson used 1/2
of the sugar when she was preparing dessert for her daughter's birthday cake. How much sugar did she use?(1 point)
To find how much sugar Ms. Johnson used, we need to find 1/2 of 7/8 of a cup.
To do this, we can multiply the fractions:
1/2 * 7/8 = (1*7) / (2*8) = 7/16.
Therefore, Ms. Johnson used $\boxed{\frac{7}{16}}$ of a cup of sugar.

How have people in North Africa modified the environment to make it more suitable for farming?
People in North Africa have made various modifications to the environment to make it more suitable for farming. Some of these modifications include:
1. Irrigation Systems: One of the key modifications is the development and implementation of irrigation systems. These systems help bring water to arid regions, enabling agriculture in areas that would otherwise be unsuitable for farming.
2. Terracing: Terracing is a technique where farmers create level steps on hillsides. These steps help to prevent soil erosion and retain water, making it easier to cultivate crops on sloped terrains.
3. Oasis Farming: In desert regions, people have established oasis farming, where they tap into underground water sources to create verdant areas for agriculture. These oases serve as havens of cultivation amidst harsh desert conditions.
4. Crop Selection: Farmers in North Africa have adapted their choices of crops to the regional climate and soil conditions. They have selected and cultivated crops that are well-suited to the arid environments, such as dates, olives, barley, and citrus fruits.
5. Desert Greening Projects: In recent years, there have been initiatives to combat desertification and reclaim deserted lands for agriculture. Techniques like afforestation, where trees are planted to prevent desert encroachment, have been employed to create more suitable environments for farming.
By implementing these modifications, people in North Africa have been able to overcome the challenges posed by the arid and semi-arid climate and cultivate crops to support their communities.

What is the function of osteoblasts in the body?
Osteoblasts are specialized cells involved in bone formation and growth. Their main function is to synthesize and secrete the components of the bone matrix, which consists mainly of collagen and other proteins that provide the framework for ossification or the process of bone mineralization.
Osteoblasts play a crucial role in bone development, repair, and remodeling. They are responsible for producing and depositing new bone tissue, contributing to bone growth during childhood and adolescence, and also to the repair of bone fractures or injuries.
Additionally, osteoblasts have some regulatory functions in the body. They participate in the regulation of calcium and phosphate levels in the blood by aiding in the deposition and release of these minerals from bones.
Overall, osteoblasts are essential in maintaining bone health and integrity by ensuring the continuous formation and remodeling of bone tissue throughout life.
What is the function of osteoblasts in the body?
a, They respond to changes in the environment.
b, They provide structure and support.
c, They control voluntary movements.
d, They help break down food within the stomach.
The correct answer is b, They provide structure and support.
Osteoblasts are specialized cells that are responsible for bone formation and growth. They produce and deposit the organic components of the bone matrix, such as collagen and other proteins, which provide the framework for bone development. Osteoblasts help in creating new bone tissue and contribute to the overall structure and support of the skeletal system.

The correct answer is:
- Cells maintain internal stability.
Homeostasis refers to the body's ability to maintain a relatively stable internal environment despite external changes. This balance is achieved through various mechanisms, and one significant contributor is the role of cells. Cells are responsible for maintaining internal stability by regulating temperature, pH levels, nutrient balance, and other variables necessary for proper functioning. Through processes like feedback loops and signal transduction, cells continuously monitor and adjust the internal conditions to maintain homeostasis.
