what are 3 fractions that are greater than 1/2 but less than one (50 points)

Answers

Answer:

2/3, 3/4, and 4/5.

Step-by-step explanation:

Three fractions that are greater than 1/2 but less than 1 are 2/3, 3/4, and 4/5.

To write three fractions that are greater than 1/2 but less than 1, the following calculation must first be performed:

1/2 = 0.5

Therefore, the fraction must have a value between 0.5 and 1.

2/3 = 0.666

3/4 = 0.75

4/5 = 0.80

Therefore, three fractions that are greater than 1/2 but less than 1 are 2/3, 3/4, and 4/5.

Answer:

2/3, 3/4, and 4/5

A story employee walked around and counted a total of 246 legs. How many of the animals are
dogs?

Answers

Answer: 52 Dogs

Hi, I hope this helps you :D Good Luck !

Step By Step:

Let d = number of dogs

b = number of birds

d+b = 71

Birds have 2 legs and dogs have 4 legs

4d+2b = 246

Multiply the first equation by -2

-2d-2b = -142

Add this to the second equation

-2d-2b = -142

4d+2b = 246

--------------------------

2d + 0b = 104

Divide each side by 2

2d/2 = 104/2

d = 52

There are 52 dogs

Answers

You can use the fact that the corresponding values from both the columns are taken into ordered pair (x,y) form to plot them on the 2d graphs (for 2 data values' set)

The scatter plot best representing the data in the table is given by

Option D: Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

How are ordered pairs formed for plotting 2d data?

There are two axis in the graph. Horizontal axis and vertical axis. The independent variable is plotted on horizontal axis and dependent variable's values are plotted on vertical axis.

Since the temperature is measured on each value of depth, thus, depth is independent and temperature is depending on the depth.

The data points are ordered as

(independent variables' value, dependent variables' value at that value of independent variable)

Thus, for the given table, we will have:

(0, 23.5), (500, 12), ... points.(it is denoting like what was the value of second variable when first variable was this. Like when depth was 0, temperature was 23.5 degrees Celsius, and so on).

Thus,

The scatter plot best representing the data in the table is given by

Option D: Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

From a point T ,a man moves 12km due west and then moves 12km due south to another point Q. Calculate the bearing of T from Q

Answers

The bearing is 45° south of west.

How to find the bearing between two points?

Let's assume that:

The point T is the point (0km, 0km).East is the positive x-axisNorth is the positive y-axis.

Then, if the man moves 12 km due west and then 12 km due south, the new position is:

( 0km - 12km, 0km - 12km) = (-12 km, -12km)

This lies just in the middle of the third quadrant, so we have 90° per quadrant plus half of that:

90° + 90° + 45° = 225°

This is the angle measured from the positive x-axis, which is the east.

If we consider the negative x-axis, which is the west, the angle would be:

θ = 45°

This means that the bearing is 45° south of west.

One weekend, 600 tickets were sold to a carnival for a total of $2400. If an adult's ticket costs $6 and a child's ticket costs $4, how many adults and how many children went to the carnival ?

Answers

Answer:

adults : 0 children: 600

Step-by-step explanation:

x + y = 600

6x＋4y = 2400

4×(x + y = 600) = 4x＋4y = 2400

(6x＋4y = 2400) － (4x＋4y = 2400) = x=0
