On Tuesday, Jennifer will mix Crunchy Grain cereal
with Super Grain cereal for her breakfast. Super
Grain cereal provides 240 calories per cup. If the total
number of calories in one cup of Jennifer's mixture is
270, how much Super Grain cereal is in one cup of
the mixture?
270, how much super grain cereal is in one cup?
Answer:
there are 1/4 cups of Super Grain Cereal in the mixture
Explanation:
Super Grain cereal provides 240 calories per cup. Thus, for s cups of Super Grain cereal, there will be 240s calories
Crunchy Grain cereal provides 210 calories per 3/4 cups. Thus, 210 ÷ 3/4 per cup.
210 ÷ 3/4 = 280 calories, For c cups of Crunchy Grain cereal, there will be 280c calories
Jennifer mixes c cups of Crunchy Grain cereal, having 280 calories and s cups of Super Grain cereal, having 240 calories to get a final 1 cup mixture containing 270 calories, which can be expressed mathematically as:
280c + 240s = 270 ------- eqn(1)
Since, s cups of Super Grain cereal and c cups of Crunchy Grain cereal equals 1 cup, of the final mixture
c + s = 1 ------- eqn(2)
from eqn(2),
c = 1 - s
substitute c = 1 - s into eqn(1)
280(1 - s) + 240s = 270
280 - 280s + 240s = 270
- 40s = 270 - 280
-40s = -10
s = (-10)/(-40)
s = 1/4
Therefore, there are 1/4 cups of Super Grain Cereal in the mixture

The serving made by Jennifer on Tuesday contains 1/4 cup of Super Grain cereal. Thus, option B is correct.
What is the mathematical expression?The mathematical expression is given as the representation of the quantities in terms of variables.
The complete question is given in the image attached below.
The serving of 3/4 cup of Crunchy cereal = 210 calories
The serving of x cup of Crunchy cereal = 210/3/4 * x
The serving of x cup of Crunchy cereal = 280x calories
The serving of 1 cup Super Grain cereal = 240 calories
The serving of y cup of Super Grain cereal = 240y calories
The total serving made by Jennifer on Tuesday = 270 calories
280x + 240y = 270 calories
The serving made by Jennifer = 1 cup
x + y = 1 cup
x = 1 - y
Substituting the value of x in the equation of calorie:
280 (1 - y) + 240y = 270
280 - 280y + 240y = 270
280 - 270 = 280y - 240y
y = 1/4
The serving of super grain cereal made by Jennifer on Tuesday was y cup. Thus, super grain cereal in one cup was 1/4. Hence, option B is correct.

how can we clasify vertebrates
Answer:
Most everything else is a vertebrate, with a backbone and other bones. Vertebrates can be classified into five groups, based on their skin covering, how they reproduce, how they maintain body temperature, and characteristics of their limbs (arms and legs, or their equivalent such as wings or fins).

Read the persuasive text below. Identify the author's claim in the text. Write one sentence that expresses what the
author is saying. Then explain how the author used evidence to support the claim.
Zoos have always been a popular destination. But more people are waking up to the fact that zoos are not good.
They re realizing that zoos are an outdated, cruel form of entertainment where animals are put on display for
humans. Instead of zoos, we should create more wildlife sanctuaries and reserves. It's time to free all caged
animals.
Most wild animals roam areas that cover hundreds of miles. However, animals in many zoos are forced to live in
small, concrete floored cages. Studies have shown that this environment causes unnatural and obsessive
behavior. These behaviors include pacing, swaying, and even harming oneself
Zoos also fail to consider the unique behavior traits of wild animals. For example, some animals are shy and
prefer to be left alone. In zoos, these animals are always surrounded by people. A study at a zoo in Belfast,
Ireland, found that gorillas acted more aggressively when there were more visitors around their cages.
Many zoos say that they protect animals that are in danger of dying out in the wild. But this claim is false. A study
found that only 1,200 out of the world's 10,000 zoos support wildlife conservation. Most zoos focus on animals
that are popular rather than endangered.
Answer:
The author makes this claim in the passage: Keeping animals in zoos is cruel and unfair to the animals.
The author supports this claim by discussing three major problems with zoos. The first problem is that zoos cause behavior problems in animals. The author supports this claim by mentioning studies that prove the claim. The author also states that zoos do not consider the specific traits of different animals. The author cites a study of a zoo in Belfast, Ireland, to support this claim. Lastly, the author states that zoos do not focus on protecting endangered animals. The author supports this claim by noting the number of zoos worldwide that support wildlife conservation.

Answer:
The importance of giving a hand is greater than donating money,
since it creates a positive sense of belonging. This includes your behavior towards other people, but also your behavior towards animals and plants who share our planet. You would help save animals and their habitats if you volunteered, and everyone should applaud such a noble act.
