There are four significant digits.

Any numbers that's not 0 counts as a significant digit. Since the zeroes in this number are either between two numbers or behind a decimal point, they also count as significant.

The caloric density of foods is a useful tool when comparing calorie counts. The table shows typical serving sizes for several f

mezya [45]

Answer:

Medium apple < Large hard boiled egg < raisins < cheddar cheese

Step-by-step explanation:

1. Cubic inch cheddar cheese ;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 69 / 17 = 4.0588cal/g

approximately 4.1cal/g

2. Large hard boiled egg;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 78 / 50 = 1.56cal/g, approximately 1.6cal/g.

3. Medium apple;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 72 / 138 = 0.52cal/g

4. Raisins;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 129 / 43 = 3cal/g

The foods with the lowest density to the highest is,

Medium apple < Large hard boiled egg < raisins < cheddar cheese

Central Park in New York City is shaped like a rectangle. On a map of the park

mariarad [96]

Answer:

Step-by-step explanation:

Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),

(-1.25, 0.25), and (1.25, 0.25)

The length L of the shape will be:

L = 0.25 - ( - 0.25 )

L = 0.25 + 0.25

L = 0.5

The width of the shape will be:

W = 1.25 - ( - 1.25)

W = 1.25 + 1.25

W = 2.5

Perimeter P = 2L + 2W

Substitute the Length and the width into the formula

P = 2(0.5) + 2(2.5)

P = 1 + 5

P = 6 metres

Therefore, the perimeter of the shape is 6 metres

The cost per student of a ski trip varies inversely as the number of students who attend. It will cost each student $250 if 24 s

mars1129 [50]

ANSWER

30 students

EXPLANATION

The cost per student varies inversely as the number of students.

Inverse proportion is written as:

$\begin{gathered} y\propto\frac{1}{x} \\ y=\frac{k}{x} \\ \text{where k = constant of proportionality} \end{gathered}$

Let the cost per student be y.

Let the number of students be x.

It will cost each student $250 if 24 students attend. This means that:

$\begin{gathered} 250=\frac{k}{24} \\ \Rightarrow k=250\cdot24 \\ k=6000 \end{gathered}$

If the cost is down to $200, it means that y is now $200.

That is:

$\begin{gathered} 200=\frac{6000}{x} \\ \Rightarrow x=\frac{6000}{200} \\ x=30\text{ students} \end{gathered}$

Therefore, 30 students could attend.
