Banana Cupcakes
makes 10 cupcakes

1 cup granulated sugar

cup vegetable oil

1 large egg

4 tablespoons sour cream

2 medium-sized ripe bananas, mashed

1 cups all-purpose flour

1 teaspoon baking soda

teaspoon salt

1 teaspoon vanilla extract

pinch of nutmeg

You will use the recipe above to answer the following questions:

This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

Answers

Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.

Step-by-step explanation:

Here we have a recipe that works for 10 serves.
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

There are 4 lines of symmetry the image have. Th correct option is option D among all the given options.

What is lines of symmetry?

A form or item is divided into two equal as well as symmetrical portions by a line of symmetry. Because it separates the figure symmetrically and the separated portions resemble mirror images of one another, we also refer to this line as the axis of symmetry or the mirror line.

Symmetric figures are any form or figure that can be split into two equal halves by a line. Asymmetric shapes and objects are those that are asymmetrical yet do not resemble one another when split into two sections. There are 4 lines of symmetry the image have.

Therefore, there are 4 lines of symmetry the image have. Th correct option is option D.

Gabby bought a backpack and 3 notebooks for $40.66. What is the total tax if the rate is 8%?

Answers

Answer:

It's $3.25 in tax

Step-by-step explanation:

Answer:

$3.24

Step-by-step explanation:

You would first have to figure out the cost of each notebook with tax so you would divide 40.66 by 3

40.66/3 = 13.55

So each notebook costs $13.55 with tax. Now, I multiplied 13.55 by 0.08. I would multiply it by 0.08 because 8% in decimal form is 0.08.

13.55*0.08 = 1.08

I got the answer 1.08. 1.08 is the tax for each notebook so I would multiply it by 3 to figure out the total tax.

1.08*3 = 3.24

Hence, the total tax is $3.24.

Your grandma wants to cover her living room with wallpaper. To know how much wallpaper to order, you need to find the surface area of her living room walls. If her living room is 15 ft by 13 ft and each wall is 8 ft high, how many square feet of wallpaper does she need to order? Explain using complete sentences and proper grammar.

Answers

Answer:

448 square feet.

Step-by-step explanation:

First off lets calculate the required wallpaper for the two walls which have lengths 15 ft, 15*8*2=240 is the answer as 8 and there are 2 walls so we multiply by 2 then we calculate the other 2 walls with lengths 13 ft, 13*8*2=208 then we finally add them 240+208=448.

The answer is 448 square feet

Sandy used a virtual coin toss app to show the results of flipping a coin 80 times, 800 times, and 3,000 times. Explain what most likely happened in Sandy's experiment.

Choice A: Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments.
Choice B: Sandy's experimental probability was closest to the theoretical probability in the experiment with 80 flips.
Choice C: Sandy's experimental probability was closest to the theoretical probability in the experiment with 800 flips.
Choice D: Sandy's experimental probability was closest to the theoretical probability in the experiment with 3,000 flips.

Answers

As the number of coin flips increases, the experimental probability should get closer and closer to the theoretical probability. This is known as the law of large numbers. Therefore, it is most likely that Sandy's experimental probability was closest to the theoretical probability in the experiment with 3,000 flips, as this is the largest sample size. The correct answer is Choice D: Sandy's experimental probability was closest to the theoretical probability in the experiment with 3,000 flips.

Choice D would be your answer. Sandys experimental probability was closest to 3000 flips when I calculated this out.

what point below is the solution to the expression 2x+y=12
A) (4,2) C) (8,-1)
B) (3,6) D) (0,6)

Answers

The answer is B. If you substitute 3 for x and 6 for y, you get 2(3)+(6)=12, and that simplifies to 6+6=12, which then adds up to 12=12. Hope this helps!

Answer:

Step-by-step explanation:

It's B.

Let's rewrite the expression like this :

2x+y=12 ⇒ y=12-2x

and try given values for x :

if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrong

How did you decide where to place your line of best fit? Describe your reasoning.

Answers

Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.

So basically the units are counting up by 5.

The x axis is age in years and y axis is the number of US states named in 60 seconds.

Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.

(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)
