Tom made a vegetable pizza and a pepperoni pizza. he cut the vegetable pizza into 5 slices and the pepperoni pizza into 10 equal slices Tom's friends ate 2 slices of vegetable pizza and 4 slices of pepperoni pizza. Construct Arguments Tom says his friends ate the same amount of vegetable pizza as pepperoni pizza how could that be true?**​

Answers

I may not be the best at this but I believe that Tom’s friends ate the same amount of pepperoni pizza to vegetable pizza because He cut the pizza into 5 slices as to the pepperoni into 10 slices is. The fraction of Vegetable to Pepperoni is 1/2 so 2 vegetable slices is the same amount as 4 slices because the pepperoni pizza is in smaller sizes compared to the Vegetable pizza.

Answer:

That could be true because they are equivalent.

Step-by-step explanation:

They are equivalent because one slice of the vegtable pizza is equal to 2 little slices 1/5=2/10 , 2/5 = 4/10 , 3/5 = 6/10 , 4/5 = 8/10 5/5 = 10/10 . So you basicly cut each fifth into half

The median in statistics is discussed below.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is the median value.

The median is the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median.Mathematically, we can write -

        [tex]$\mathrm{Med}(X) = \begin{cases} X[\frac{n+1}{2}] & \text{if n is odd} \\ \frac{X[\frac{n}{2}] + X[\frac{n}{2}+1]}{2} & \text{if n is even} \end{cases}[/tex]

Therefore, the median in statistics is discussed above.

The wildflowers began blooming by my house at the beginning of March. The first week there were 88 blooms. After week two, there were 176 flowers in bloom. If the flowers continue to bloom at the same rate each week, how many flowers will there be after 6 weeks?
A. 264
B. 462
C. 528
D. 536

Answers

Answer: C. 528

Explication: 88x2 weeks= 176 so 88x6weeks=528
First, there were 88 blooms in one week, now they are asking how many flowers will there be after 6 weeks, so you take 88 multiply by 6 (88x6) which gives you 528...so technically you will get C.528

THE STORY IS DOWN BELOWPioneering in Florida1 Ben Hill Doster moved his family from Atlanta, Georgia, to Jupiter, Florida, in 1894 to help his sister. Her husband had died, but she hoped to own 160 acres of land there as a homestead. She just needed to live on it for one more year.2 Soon after they arrived, Ben Doster took his family on a boat ride up the Loxahatchee River. Suddenly, the air turned cold. Feeling agitated, Doster rowed hurriedly back to the tiny cabin, and the family huddled inside near a roaring fire. That night they heard sounds like gunshots, but the sounds turned out to be the trunks of orange trees exploding when they froze. The next morning, they awoke to find their 16-acre pineapple patch frozen and their garden vegetables dead.3 Many new settlers left soon after the Big Freeze of 1894, but the Doster family stayed. They replanted their pineapples and their garden, and they also opened up a general store. Slowly, Dosters wife and two daughters learned to love the land of southern Florida and respect its dangers.4 In their first year, they began to recognize the sounds of the swamp at night. They thought of it as a nightly serenade; different types of frogs had distinctive calls. The tiniest frogs chirped tea table, tea table. The bullfrogs boomed rung, rung, rung. Owls hooted and birds called to their mates. Sometimes, alligators bellowed. 5 But one night they awoke to hear the painful scream of a woman. She sounded like she was nearby, so Mrs. Doster prepared to go outside to look for her. But Ben Doster stopped her at the door. He explained that when panthers screamed in the night, they sounded exactly like a woman in pain. No one should go outside to help because panthers were dangerous.6 One of Dosters daughters, Dora, later wrote about her memories of the time. She wrote lovingly of mangrove and cypress trees hung with Spanish moss. She saw white herons standing like statues waiting to pluck fish from the shallow water. Yellow and orange butterflies danced down a path in front of her. She thought the ocean before a hurricane looked like a vicious monster, curling its jaws and showing its teeth. She learned to watch for the poisonous snakes that lived along the paths.7 Doras mother was a strong and brave woman. She stood up to panthers, alligators, and hurricanes. But for her, there was more than danger, beauty, and excitement. Doras father worked long hours at the store. Dora thought her mother must have gotten very homesick and lonely at the cabin. She saw her mother watch the trains pass to the east and listen to their mournful wails. Dora believed she often wanted to be on one of those trains, headed back home. She had grown up in Atlanta and had not planned to become a pioneer.THAT'S the FIRST ONE. NOW, THE SECOND IS THIS LINK.
