Are these terms alike or unlike: 2xy and 2xyz

Answers

Answer:

Unlike

Step-by-step explanation:

When it comes to like terms, the numbers must have the same ending variable, 2xy and 2xyz do not have the same ending variable, which seeing it, one ends with 2xy and the other with 2xyz. Therefore these terms are not the same and the answer is unlike.

Answer:

Step-by-step explanation:

Because the graph below is misleading, which magazine appears to have about four times the circulation of circuitry today?
a. American Ampersand
b. Waffle all World
c. Fossil Week
d. None of them​

Answers

Answer:

A. American Ampersand

Step-by-step explanation:

Question is asking for what appears to be four times the circulation and American Ampersand appears to be four times the circulation.

Since the graph below is misleading, a magazine which appears to have about four times the circulation of circuitry today is: A. American Ampersand.

What is a graph?

A graph can be defined as a type of chart that is typically used for the graphical representation of data such as magazine circulation in a country, by using both the horizontal and vertical lines, which are called x-axis and y-axis respectively.

By critically observing the misleading graph above, we can deduce that American Ampersand is a magazine which appears to have about four times the circulation of circuitry today because its bar is the smallest among others.

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below. 2,3,,4,4 6,6,7 After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Renee used?

Answers

Answer:

2 cm, 3 cm or 4 cm

Step-by-step explanation:

Diameters of potatoes:

2, 3, 4, 4, 6, 6, 7

Median is:

4 cm

After one potato used the median becomes 5 cm.

Out of 6 potatoes left, the two in the middle should give 5 cm in average

This is 4 cm and 6 cm.

Renee must have used one of the 4 potatoes on the left: 2 cm, 3 cm or 4 cm

Based on the information, determine which sides of quadrilateral ABCD must be parallel m angle A= 67°, m angle b = 120°, m angle c=73°, m angle d =100°

Answers

Answer:

None of the sides are parallel.

Step-by-step explanation:

Quadrilaterals are all figures or shapes bounded by four sides. Some common examples are: square, rectangle, trapezium, rhombus, parallelogram etc.

Two or more lines are said to be parallel, if none of the lines meet when extended till infinity. i.e they are at [tex]180^{o}[/tex] to one another.

Given a quadrilateral ABCD with the measures of angles as given, none of its sides would be parallel.

2) Richard, Henry and Gavin share some sweets in the ratio 4:1:3. Richard gets 7 more sweets
than Gavin. How many sweets does Henry get?​

Answers

Answer:

6

Step-by-step explanation:

Richard gets 7 more sweets than Gavin which would probably make Richard have the most so in total he should have around 8 whilst Gavin has 1 so right now we have 4:1:?. Basing off the fact that Richard would have the most sweets Henry would have to have 6 sweets to be able to divide half of it for 3. 4:1:3

Answers

Answer: 10

Step-by-step explanation:

Question A:

The formula to find the hypotenuse is c²=a²+b²

So you would insert the numbers into the formula which would be c²=8²+6²

8²=64

6²=36

36+64=100

So c²=100

Then you want to find c on its own so you have to square root 100.

The square root of 100 is 10.

You have to use this method for the rest of the triangles.

The hypotenuse of the triangles are solved

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

a)

a = 8

b = 6

Now , From the Pythagoras Theorem , The hypotenuse² = base² + height²

c = √ ( 8 )² + ( 6 )²

c = √100 ≈ 10

b)

a = 11

b = 7

c = √170 ≈ 13.0

c)

a = 13

b = 6

c = √205 ≈ 14.3

Hence , the hypotenuse of the triangles are solved
