Ms. Van Tress has 134 students. She sees 38 students before lunch and 96 students after lunch.
liubo4ka [24]

Answer:

<em />\%Percent = 28\%<em> ---- Before Lunch</em>

<em />\%Percent = 72\%<em> --- After Lunch</em>

<em />

Step-by-step explanation:

Given

Total = 134

Before\ Lunch = 38

After\ Lunch = 96

Required

Determine the percentage of students seen in both cases.

This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%

i.e

\%Percent = \frac{Seen}{Total} * 100\%

- Before Lunch;

\%Percent = \frac{Before\ Lunch}{Total} * 100\%

\%Percent = \frac{38}{134} * 100\%

\%Percent = \frac{3800\%}{134}

<em />\%Percent = 28\%<em> --- approximated</em>

- After Lunch;

\%Percent = \frac{After\ Lunch}{Total} * 100\%

\%Percent = \frac{96}{134} * 100\%

\%Percent = \frac{9600\%}{134}

\%Percent = 72\% <em>--- approximated</em>

What is the area of parallelogram abcd? HELP THIS IS TIMED​
Anastaziya [24]

Answer:

13.04 square units

Step-by-step explanation:

Since this is a parallelogram, we only need to solve for the sides of 2 sides.

We can use the distance formula.

The distance from A --> D :

A(3,6) and D(2,2)

2 - 3 = -1

-1^2 = 1

2 - 6 = -4

-4^2 = 16

1 + 16 = 17

\sqrt{17}

The distance from A --> B :

A(3,6) and B(6,5)

6 - 3 = 3

3^2 = 9

5 - 6 = -1

-1^2 = 1

9 + 1 = 10

\sqrt{10}

Multiply.

\sqrt{10}*\sqrt{17}=13.04

*<em>Rounded to the nearest hundreth</em>
