Statements 1 and 4 are true, the others are false.

Step-by-step explanation:

Step 1:

First, we need to convert the fractions into decimals so they can be compared to each other on a common scale.

The birch tree ; \frac{1}{7} = \frac{1}{7} (100) = 0.142(100)= 14.2\%,

The pine tree ; \frac{7}{9} = \frac{7}{9} (100) = 0.777(100)= 77.7\%,

The maple tree ; \frac{1}{4} = \frac{1}{4} (100) = 0.250(100)= 25\%,

The oak tree ; \frac{11}{23} = \frac{12}{23} (100) = 0.478(100)= 47.8\%.

Step 2:

Now we check each of the given options to so which are true.

Option 1; Most students found a pine tree, 77.7% is more than any other tree, so it is true.

Option 2; the maple tree > the pine tree. The maple tree was 25% while the pine tree was 77.7%, so it is false.

Option 3; the birch tree > the oak tree. The birch tree was 14.2% while the oak tree was 47.8%, so it is false.

Option 4; the pine tree > the birch tree. The pine tree was 77.7% while the birch tree was 14.2%, so it is true.

Option 5; the maple tree > the oak tree. The maple tree was 25% while the oak tree was 47.8%, so it is false.

At Cindy's birthday each guest will get one-third of a medium sized pizza. There will be 12 people at the party, including Cindy
tiny-mole [99]

Answer: 4 pizzas

Step-by-step explanation:

There are to be 12 people at the party.

Each person is expected to take 1/3 of a pizza.

The total number of pizza needed is therefore:

= No. of people * quantity of pizza

= 12 * 1/3

= 4 pizzas

<em>Note: Answer would be 6 if each guest wanted 1/2 of a pizza. </em>

One endpoint of a line segment is (–6, 4), and the midpoint of the segment is (–2, 7). What are the coordinates of the other end
Arturiano [62]

Answer:

A. (2, 10)

Step-by-step explanation:

If there are two points (x1,y1) and (x2,y2) on a coordinates plane then

coordinates of the midpoint is given by (x1+x2)/2, (y1+y2)/2

__________________________________________________

Given

one endpoint is (–6, 4) and midpoint is (–2, 7)

let coordinates of other endpoint be (x,y)

now if one endpoint is (–6, 4) and other endpoint is (x,y)

then coordinates of midpoint is ((-6+x)/2 , (4+y)/2)

while the coordinates of midpoint given  is  (–2, 7)

thus (–2, 7) should be equal to ((-6+x)/2 , (4+y)/2)

-2 = (-6+x)/2             and   7 = (4+y)/2

=> -2*2 = -6+x                 => 7*2 = 4+y

=> -4 = -6+x                    => 14 = 4+y

=> -4+6 = x                     => 14-4 = y

=> x = 2                           => 10 = y

Thus, coordinates of the other endpoint is(2,10)

Kite WXYZ is graphed on a coordinate plane. What is the area of the kite?
Misha Larkins [42]

Answer:

14 square units

Step-by-step explanation:

There are several ways we can find the area.  Probably the easiest is to cut the kite in half vertically and find the area of each triangle.  The area of the kite will be double that.

The height of the kite is 7 units, and the width is 4 units.  So each triangle will have a base of 7 and height of 2.

A = 1/2 bh

A = 1/2 (7) (2)

A = 7

The area of the kite is double that, so:

2A = 14
