Step-by-step explanation:

y-intercept: (0,1)

rate of change: 2/3

Y-intercept: I found this because the y-intercept is when x=0, and where the line crosses through the y-axis.  So, we can see that the y-intercept is (0,1)

Rate of change: The rate of change is another word for slope, or rise/run, so we can see, from point (0,1), that the rise is 2 units up and 3 units to the right to another point where the line crosses a whole number point.

Hope this helps :)

PART A
Maya has a recipe for blueberry chocolate chip muffins. She doesn't like a lot of oats but loves blueberries, so she is using 3/4 of the number of oats called for and increasing the number of blueberries by 1/4 of the original amount. She then wants to double her new recipe.

Ingredient Amount (cups)
Blueberries 34

Chocolate Chips 1

Oats 12

White Sugar 1

How many cups of oats will Maya need? Write your answer as a fraction in simplest form.

PART B:

How many cups of blueberries will Maya need? Write your answer as a mixed number in simplest form.

Answers

PART A:

Maya is using 3/4 of the original amount of oats, so she will need:

(3/4) * 12 cups = 9 cups

She wants to double her new recipe, so the final amount of oats she will need is:

2 * 9 cups = 18 cups

Therefore, Maya will need 18 cups of oats.

PART B:

Maya is increasing the amount of blueberries by 1/4 of the original amount, which is:

(1/4) * 34 cups = 8.5 cups

So the new amount of blueberries she will use is:

34 cups + 8.5 cups = 42.5 cups

To double the recipe, Maya will need:

2 * 42.5 cups = 85 cups

Writing the answer as a mixed number:

85 cups = 2 * 34 cups + 17 cups

Therefore, Maya will need 2 and 17/34 cups of blueberries.
Maya wills need 2 17/34 cups of blueberries

In a baseball tournament teams get 5 points for a win 3 points for a tie and 1 point for a loss. nathans team has 29 points.
a) use and organized list to show how many differnt combinations of wins,ties and losses nathans team could have.
b)what is the probability that nathans team had more losses than ties?

Answers

a) To create an organized list, we can start with the number of wins and find all possible combinations of ties and losses that would result in 29 points:

- 1 win: 24 losses or 22 losses and 1 tie or 20 losses and 2 ties or 18 losses and 3 ties or 16 losses and 4 ties or 14 losses and 5 ties or 12 losses and 6 ties or 10 losses and 7 ties or 8 losses and 8 ties or 6 losses and 9 ties or 4 losses and 10 ties or 2 losses and 11 ties or 13 ties
- 2 wins: 19 losses or 17 losses and 1 tie or 15 losses and 2 ties or 13 losses and 3 ties or 11 losses and 4 ties or 9 losses and 5 ties or 7 losses and 6 ties or 5 losses and 7 ties or 3 losses and 8 ties or 1 loss and 9 ties
- 3 wins: 14 losses or 12 losses and 1 tie or 10 losses and 2 ties or 8 losses and 3 ties or 6 losses and 4 ties or 4 losses and 5 ties or 2 losses and 6 ties or 7 ties
- 4 wins: 9 losses or 7 losses and 1 tie or 5 losses and 2 ties or 3 losses and 3 ties or 1 loss and 4 ties
- 5 wins: 4 losses or 2 losses and 1 tie or 1 loss and 2 ties

b) To find the probability that Nathan's team had more losses than ties, we need to count the number of combinations where the number of losses is greater than the number of ties. From the list above, we can see that there are 28 such combinations (all except the one with 13 ties). To find the probability, we need to divide the number of favorable outcomes by the total number of outcomes:

Probability = 28 / 64 = 0.44

So the probability that Nathan's team had more losses than ties is 0.44, or 44%.

Answers

Answer: 7221.76 m2

Step-by-step explanation:

Let's first find the area of the rectangle.

The formula is lengthxwidth or LxW

Therefore the area of the rectangle is 85x56= 4760 m2

Now let's find the area of the semicircles. They are two equal semicircles, so we can put it together into one circle.

The formula for the area of a circle is πr2

They gave us the diameter not the radius, so we have to find the radius.

To find the radius, we take the diameter/2 which 56/2 = 28 m

Area= 28x28x3.14= 2461.76

The total area= 2461.76+4760= 7221.76 m2

Find the product of:
3.8 & 6.9

Answers

To find the product of 3.8 and 6.9, we can multiply the two numbers together:

3.8 × 6.9 = 26.22

Therefore, the product of 3.8 and 6.9 is 26.22.

Answer:

the product of 3.8 and 6.9 is 26.22.

Step-by-step explanation:

The product of 3.8 and 6.9 can be found by multiplying the two numbers. Using a calculator or long multiplication, we get:

3.8 x 6.9 = 26.22

Therefore, the product of 3.8 and 6.9 is 26.22.

It is important to note that when finding the product of two decimal numbers, we need to make sure to place the decimal point correctly in the final answer. To do this, we count the total number of decimal places in the two numbers being multiplied, and then place the decimal point in the answer that many places from the right. In this case, both numbers have one decimal place, so the answer has one decimal place as well.

So, totally there are 37 different combinations.


(Question 2)

Number of Losses that Nathan can have = 29/1

                                                                     = 29 Losses

Number of Ties that Nathan can have = 29/3

                                                                = 9 Ties

Total = 29 + 9

         = 38

Probability of Losses = 29/38

                                    = 76% (Approximately)

Probability of Ties = 9/38

                               = 24% (Approximately)

We can easily figure out that the Probability of Losses is more than the Probability of Ties.

The Probability of Losses is more than Probability of Ties by —

Probability of Losses - probability of Ties = 76 - 24 = 52%

All faces of a bench except the two faces that rest on the ground will be coated with water-resistant paint. The bench is a right prism. What is the total area to be coated with the paint? Show your work.

Answers

Answer:

Step-by-step explanation:

234 is the answer

The total area to be painted is 8,316 square inches.

How to calculate total area?

The bench has a rectangular base with dimensions 63 in by 14 in. The height of the bench is 54 in. The two faces that rest on the ground do not need to be coated with paint, so the total area to be coated is the sum of the areas of the four remaining faces.

The area of one of the longer faces is:

63 in × 54 in = 3,402 in²

The area of the other longer face is the same, so the total area of the longer faces is:

2 × 3,402 in² = 6,804 in²

The area of one of the shorter faces is:

14 in × 54 in = 756 in²

The area of the other shorter face is the same, so the total area of the shorter faces is:

2 × 756 in² = 1,512 in²

The total area to be coated with paint is the sum of the areas of the four remaining faces:

6,804 in² + 1,512 in² = 8,316 in²

Therefore, the total area to be coated with paint is 8,316 square inches.
