Select the term that best describes the statement.If a polygon has eight sides, then it is an octagon.

conjunction
disjunction
negation
conditional

Answers

Answer:

The term that best describes the given statement is given by the last option i.e.

Conditional .

Step-by-step explanation:

We are given a statement:

If a polygon has eight sides, then it is an octagon.

We know that a conditional statement which is also known as the if-then statement is a statement where one part of it is a given condition or hypothesis and the second statement is a conclusion of the first statement.

It could also be symbolized as:

If p then q

where p is the hypothesis and q is the conclusion.

Hence, the term that describes this given statement is:

Conditional.

conditional 
if the polygon has 6 sides then it is a hexagon, is an example of condition sencece so the correct answer is conditional.

Can she buy enough packs ?

Answers

How many tiles does she need ?

1 square meter = 10,000 cm²
12 square meters = 120,000 cm²
Each tile = (20 cm x 20 cm) = 400 cm²
Tiles needed = 120,000 / 400 = 300 tiles

How many tiles can she buy ?

1,000 / 34.99 = 28 boxes, with 20.28 left over . . . not enough for another box.
28 boxes of 10 tiles per box = 280 tiles

Halima doesn't have enough money to buy enough tiles
to cover the wall.  She can only buy 280 tiles, but it would
take 300 to cover the wall.

She can cover 280/300 = 93 and 1/3 percent of the wall,
leaving 6 and 2/3 percent with the old ugly plaster showing.
Maybe she could leave the bare part down at the bottom, and
then hide it with a table up against the wall.
 



im pretty sure she can only cover 380 of it

Find the unit rate in feet per second
300 yards over 1 minute

Answers

In order to find the unit rate in ft / sec of 300 yards / min. We first have to elicit the conversion values for each unit of measurement, this will allows us identify how much will we multiply in order to get the goaled value.
Conversion values:
1.    1 yard = 3 feet
2.    1 minute = 60 seconds

Solution:
1.   
300 yards x 3 feet/1 yard = 900 feet

2.    1 minute x 60 seconds / 1 minute = 60 seconds

Thus, 900ft/60sec



Question: Find the unit rate in feet per second

300 yards over 1 minute

Answer: 15 ft per second

Reasoning: Since we are trying to find the unit rate of feet per second for 300 yards in one minute. 1 yard is 3 feet. 300 x 3= 900 Now divide 900 by 60 for the seconds. 900/60= 15

So 15 feet per second :)

Shaun is 4 years older than her sister Charmaine. If the sum of their ages is 16 how old is Charmaine?A) 4 years old
B) 6 years old
C) 8 years old
D) 10 years old

Answers

Answer:

The answer is B) 6 years

Step-by-step explanation:

First of all, build an equation. With the given problem, you can come up with:

s + c = 16

In which interprets that both their ages summed up are 16. Secondly,:

s = c + 4

After you will use the typical system of equations to solve. So, plug in the second equation to the first, where s will become c + 4, and the equation is now:

c + 4 + c = 16

And finally, solve for Charmaine's age.

2c + 4 = 16

    -4     -4

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

2c = 12

c = 6

Answer:6 years old

Step-by-step explanation:

Solve 3x^2 = 6x by rewriting the equation. Show your reasoning.

Answers

Solution of the given equation3x^(2)=6x is x=2 and 0

What is an equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given,

3x^(2) =6x

Rewrite the equation

3x^(2) -6x=0

Solve the equation

3x^(2) -6x=0\n3(x^(2) -2x)=0\nx^(2) -2x=0

Therefore the roots are

x=2 and 0

Hence, solution of the given equation3x^(2) =6x is x= 2 and 0
