A watercooler contains 160 cups of water. During practice, each person on a team fills a water bottle with 3 1/3 cups of water from the cooler. How many water bottles can a team fill from a single watercooler?

Answers

Answer: Number of water bottles a team can fill  from a single watercooler = 48

Step-by-step explanation:

Given: A watercooler contains 160 cups of water.

Each person on a team fills a water bottle with [tex]3\dfrac13[/tex] cups of water from the cooler.

Here, [tex]3\dfrac13=\dfrac{10}{3}[/tex]

Now , Number of water bottles a team can fill  from a single watercooler = [tex]160\div \dfrac {10}3[/tex]

[tex]=160\times\dfrac3{10}\\\\=16\times3=48[/tex]

Hence, Number of water bottles a team can fill  from a single watercooler = 48

Number of water bottle IT team can feel a single watercooler =48

Kylie is preparing for the science fair that will take place in six weeks. She has three plants that she has grown from seeds, which she considers to have height 0 centimeters, and she is measuring their heights as she applies different treatments to each. The second plant is receiving Plant Food B. After 3 weeks, it is 10 centimeters tall. If it continues growing at this rate, how tall will it be after 6 weeks?

Answers

Might be 20 cm going based off the information after 6 weeks

The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

First we need two points (x, y) to obtain the slope.

Assuming height to be 'y' and weeks to be 'x'.

Therefore, (0, 0) and (3, 10) are the two points.

Slope(m) = (10 0)/(3 - 0).

Slope(m) = 10/3.

Slope(m) = 3.33

Now, To obtain the y-intercept.

10 = 3(3.33) + b

b = 0.01 Or neglegible.

Therefore y = 3.3x.

Now, In the 6th week, the height of plant B will be,

y = 3.33(6).

y = 19.98 or 20 cm.

jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. which expression can he use to figure out the number of holes he will need to drill

Answers

Answer: 36 / 2 1/4

Step-by-step explanation:

From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:

= 36 ÷ 2 1/4

From the expression we can then calculate the number of hours to drill. This will be:

= 36 / 2 1/4

= 36 / 9/4

= 36 × 4/9

= 16

He'll need to drill 16 holes

The pitch of a roof is the number of feet the roof rises for each 12 feet horizontally. If a roof has a pitch of 8, what is its slope expressed as a positive number?

Answers

If the pitch is 8, it means the roof raises 8 ft. per each horizontal 12 ft.
Since slope, m, is defined as the rise/run; then m = 8/12. Simplifying, we obtain a slope m = 2/3 In order to write the line of the roof as an equation, let's assume that the roof line starts at the origin (0, 0); it rises 8 units for every 12 it advances; up to the point (12, 8). At this point, the roof descends at the same rate until it reaches the point (0, 24). We need to set two equations with the given constraints: y = mx + b since the roof ascend from (0, 0) up until (8, 12) we use a positive slope: y = 2/3x + b If we use (0, 0) to define b, then the equation of this section of the roof will be:
y = 2/3x 〈0 ≤ x ≥ 12〉 At (12, 8) the roof starts descending at the same rate, then we use the negative slope m = -2/3: y = -2/3x + b Now, let's use (12, 8) to define b: 8 = (-2/3)(12) + b Simplifying, we obtain b = 16, ∴ the equation of this section of the roof will be: y = -2/3x + 16 〈12 ≤ x ≤ 24〉

what is the vertical change from point A to point B ?

What is the horizontal change to point A to point B?

Answers

Answer:

Vertical change= 1

Horizontal change= 2

Rate of change=  1/2

Step-by-step explanation:

The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

In the past, scientists have tried to copy human brains exactly. The trouble is, there is still so much that scientists do not know about how human brains work. But a group of scientists at Michigan State University have developed a new plan. They are using nature as an example to follow for robots. We know that things change and adapt in nature. These scientists want to make robots that can change and adapt, too. The robots would learn to do tasks over time. The goal is to have robots with brains that develop like human brains do, over many years.One task this team of scientists worked on was to get robots to enter and exit a room. This action is easy for humans to complete, but not for robots. The scientists used a math equation to program the robots on this task. They created a program where the robots had to work on the task in connection with other robots. The robots watched each other and took on special roles for the task. This made them more successful. Then, the robot brains that worked the best on a task were the models used for future brains. This is very much like what happens in nature. A characteristic that works well for an animal gets passed on to its babies.Overall, this group of scientists thinks that following what happens in nature is the key to creating robots that can think like humans. The robot brains will start young, like humans. Robots will learn and explore for many years. Then they will develop higher intelligence and understanding. This is very much like how human brains develop! 1 PassageProblem Solving with Peanuts and Sweet PotatoesFor years, farmers in Alabama grew cotton and nothing else. As a result, farmers had damaged fields that could no longer cultivate crops. The fields broke down from planting the same thing year after year. Then, in 1914, a pest called a boll weevil destroyed crops. The solution to this problem came from George Washington Carver, an African-American scientist and inventor. He discovered that the soil in Alabama grew peanuts and sweet potatoes well. Carver suggested that farmers grow peanuts and sweet potatoes to help the soil.This plan worked. Farms began producing peanuts and sweet potatoes. However, not many people bought these foods. Farmers struggled to earn a living. Carver responded to this situation with more research. He wanted farmers to keep planting these crops. He experimented and made products from peanuts and sweet potatoes. Carver made 300 other things from peanuts, such as flour, milk, ink, and dye. He made about 100 products from sweet potatoes, including glue and ink. By 1940, peanuts became the second leading crop to make money in the South. Carver changed how cotton was grown and made many other crops important to the South.
