A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of green results for 240 trials.

Red Orange Yellow Green Blue

Answers

Answer:

I'd guess 54

Step-by-step explanation:

If the sections are all equal sized, there's an equal chance the arrow/spinner would land on them. If you divide 240 by 5, you get 48. The closest number to 48 is 54.

I think the answer is 54

What is the equation of the line?

Answers

Answer:

y = 1/2 - 3/2

Step-by-step explanation:

All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].

-3 = 1/2(-3) + b

-3 = -1.5 + b

-1.5 = b

We can put all the information we know/solved for into the formula.

y = 1/2 - 1.5

Best of Luck!

Answer:

The equation of the line is y = 1/2x - 3/2

Step-by-step explanation:

Plug in point (-3, 3) with slope 1/2 into y = mx + b

-3 = 1/2(-3) + b

-3 = -3/2 + b

+3/2 +3/2

-------------------

-3/2 = b

hence, y = 1/2x - 3/2

Brittany went grocery shopping , she spent 4/7 of her money on fresh foods. she spent 2/3 of the remainder of her money on frozen foods. if she spent 22$ on frozen foods. how much money did she spend on fresh foods?

Answers

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

[tex] \frac{4}{7} \times y[/tex]

Remainder =

[tex]y - \frac{4}{7}y = \frac{3}{7} y[/tex]

Amount spent on frozen foods = two-thirds of remainder = $22

[tex] = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y[/tex]

[tex]\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77[/tex]

Complete step-by-step answer:

Sum of 3 consecutive odd numbers is equal to 51.

Let the odd number be ‘x’. Then the next consecutive odd number becomes ‘x + 2’ and the next term becomes x + 2 + 2 = ‘x + 4’.

Now the sum of these three odd consecutive terms = x + x + 2 + x + 4 = 3x + 6.

According to the given, 3x + 6 = 51.

⟹3x = 51 – 6

⟹x =453=15.

Hence, the numbers are 15, 17 and 19.

Note: In order to solve this type of questions the key is to consider a variable to be odd and compute the sum of three consecutive odd numbers in terms of this variable. Then by solving for this variable we can determine the numbers. Any odd number added with 2 gives an odd number itself.

Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies. The rest of the class gets nothing and begins to collectively cry. How many cookies were in the batch, to begin with?

Answers

Answer:

Step-by-step explanation:

After dylan took half of the cookies and 6 were left there were

12 before he took any

Than If Koji took a 3rd when 12 were left there were 18

Than if Paige took a 1/4 of what was left when there were 18 there were 24

This same pattern is the same for the next 2

24+6 = 30 and than 30+6 = 36

TLDR;

remove 6 per person meaning there were 36 to begin

Mrs. Balbas baked a batch of cookies for her math class.

1. Aaron takes 1/6 of the cookies:

If "C" represents the initial number of cookies, Aaron takes (1/6)C cookies, leaving (5/6)C cookies.

2. Matthew takes 1/5 of the remaining cookies:

Matthew takes (1/5)(5/6)C = (1/6)C cookies, leaving (5/6)C - (1/6)C = (2/3)C cookies.

3. Paige takes 1/4 of the remaining cookies:

Paige takes (1/4)(2/3)C = (1/6)C cookies, leaving (2/3)C - (1/6)C = (1/2)C cookies.

4. Koji takes 1/3 of the remaining cookies:

Koji takes (1/3)(1/2)C = (1/6)C cookies, leaving (1/2)C - (1/6)C = (1/3)C cookies.

5. Dylan takes half of the remaining cookies:

Dylan takes (1/2)(1/3)C = (1/6)C cookies, leaving (1/3)C - (1/6)C = (1/6)C cookies.

6. Gavin takes the last 6 cookies:

The remaining (1/6)C - 6 cookies are taken by Gavin.

7. The rest of the class gets nothing, leaving 0 cookies.

Now, let's add up the amounts taken by each student:

- Aaron: (1/6)C

- Matthew: (1/6)C

- Paige: (1/6)C

- Koji: (1/6)C

- Dylan: (1/6)C

- Gavin: 6 cookies

Adding all these together, we get:

(1/6)C + (1/6)C + (1/6)C + (1/6)C + (1/6)C + 6 = (5/6)C + 6

Since the remaining cookies are accounted for,

we know that (5/6)C + 6 = 0, which gives us C = 432.

Therefore, the initial batch had 432 cookies.

Vocabulary 1: British Poets HURRRYYYYYYYYYYYYYYYYYYYYYYY THIS IS TIMEDI hung around in the new neighborhood enjoying the sight of green trees, big whitewashed houses, and well-kept lawns where geraniums and roses of different shades were in full bloom. It had been three days since we moved to Cameron County from Reynosa, and I was eager to explore the neighborhood.2 As I lingered on the sidewalk at the far end of the block, I noticed a house that had the neatest and the best-kept lawn I had ever seen. The lawn looked like one of those paintings by an artist who puts a lot of time and effort into his work of art. I started to turn around and leave when I heard something that sounded like a bark.3 The gates were slightly open, and I could see the house and its conspicuous front yard with blooming flowers of different colors. For a fleeting moment, I was tempted to pluck one, but they looked so perfect that I decided to bend down and take a whiff of the sweet fragrance.4 As I was enjoying the view laid out in front of me, a deep voice interrupted my thoughts.5 "Aren't they lovely?" he said.6 I turned around to find a middle-aged man, probably in his late fifties. "I planted these beauties with my own hands," he added in his proud and merry voice.7 "Hi, my name is Ethan," I introduced myself.8 "Nice to meet you, Ethan! I'm Jacob," he said.9 When I told him that his garden had the best flowers in the neighborhood, his eyes twinkled, and a big grin spread across his face. I told him that I lived a few blocks away, and when I asked him about his family, he said they were on vacation. He could not leave the house, as he had a pet and a garden to look after.10 "This garden, its flowers, and the sparrows that chirp all day long on the trees in my backyard are my friends and family for now," he said and winked. "Would you like to take one of my best roses home?" he asked.11 "But they are so beautiful, and you worked so hard to make your garden look so appealing," I replied.12 "If my flowers make you happy, I'll gladly gift you one," he said and smiled.13 I was surprised and inspired by Jacob's passion for gardening and vigor for life. I headed home with a beautiful rose in my hand and a fresh zeal that my new friend had instilled in me.6Through the narrator's experience, the author explores the theme of A. travel and exploration B. nature and passion C. loneliness and grief D. remoteness and isolation In science, this law is well-known: For every action, there is an equal and opposite reaction.Consider the idea that the Reformation was an ACTION and the Counter-Reformation was the REACTION.
