at a drive-through restaurant, Casey's family ordered a small drink and m medium drinks. Anika's family ordered m medium drinks

and a large drink. Small = $1.10, Medium = $1.25, and Large = $1.50. what is algebraic expression that shows the total cost, in dollars, of both orders? Combine like terms to write an expression that is equivalent to your expression from the other question

Answer: 2.60+ 2.50 m

Step-by-step explanation:

Hi, the cost of Casey's family is equal to the price of 1 small drink (1.10) plus the price of a medium drink (1.25) multiplied by the number of medium drinks bought (m).

Same process for Anika's Family.

Casey's family cost: 1.10+ m 1.25

Anika's family cost :m1.25+ 1.50

Combining the expressions:

1.10+ m 1.25+m1.25+ 1.50

1.10+1.50+1.25m+1.25m

2.60+ 2.5 m

Total cost of both orders = 2.60+ 2.50 m

Answer:

3x-28=2x+25\\x=53

Step-by-step explanation:

Parallel lines cut by a transversal are two lines which do not cross intersected by a third line. Because lines such as m and n are parallel, we have angles which are equal to each other.

  • Corresponding Angles - angles located in the same position in each intersection. Can be shown by translating or sliding the angle down/up.
  • Alternate Interior Angles - angles located inside the parallel lines across the transversal. Can be shown by reflecting and translating or rotation.
  • Alternate Exterior Angles - angles located outside the parallel lines across the transversal. Can be shown by reflecting and translating or rotation.
  • Vertical angles - angles across a vertex from one another. Can be shown by reflection.

The angles shown here are located outside the parallel lines and across the transversal from each other. Therefore we have Alternate Exteroir angles and can set them equal to each other to solve for x.

3x-28=2x+25\\3x-2x-28=2x-2x+25\\x-28=25\\x-28+28=25+28\\x=53

We check our work and should get equal angles:

3(53)-28=2(53)+25\\159-28=106+25\\131=131

Determine whether the following statement is true or false.
shutvik [7]

Answer:

Step-by-step explanation:

In constructing a confidence interval about the mean, the central limit theorem is usually applied. This makes it possible to use the normal distribution. As the number of samples is increasing, the distribution tends to be normal. This would require using the z distribution. In the case where the sample size is small, we assume a normal distribution and use the t distribution. Therefore, the given statement is true.

Fiber One Bran Cereal boasts that it contains 57% of the Daily value of fiber you need. If 1 serving contains 14 grams of fiber,
Makovka662 [10]

The amount of fiber needed in a day is 7.98 grams

<h3>Proportions</h3>

Proportions are parts, in comparative relation to a whole.

In other words, proportions are fractions of a larger dataset

The given parameters from the question are given as:

  • Proportion of the daily value of fiber needed = 57%
  • Daily serving = 14 grams.

<h3>Amount of fiber</h3>

The amount of fiber needed in a day is the product of the proportion and the size of the daily serving.

So, we have:

Amount = 57\% \times 14g

Amount = 7.98g

Hence, the amount of fiber needed in a day is 7.98 grams
