Ron used 14 centimeters of tape to wrap 2 presents. How much tape will Ron need in all if he has to wrap 6 presents? Assume the relationship is directly proportional.

Answers

Answer: 2x7=14 present so

6x7=42

Step-by-step explanation:

2 presents=14 centimeters
6 presents= x centimeters
Cross multiply
2x=14x6
2x=84
Divide both sides by 2
X= 42
So he uses 42 centimeters of tape to wrap 6 presents

can you help me please ​

A five sided figure, the sum of all the angles must add up to 540 degrees.

In order to find x we are gonna add all the present angles and then minus the sum from 540 degrees.

76 + 144 + 112 + 125 = 457 degrees

540 - 457 = 83 degrees

Therefore x is equal to 83 degrees.

An arithmetic sequence has this recursive formula:
a1=9
an=an-1 -3
What is the explicit formula for this sequence?
A. an=9+(n-1)(-3)
B. an=-3+(n-1)9
C. an=9+(n-3)(-1)
D. an=-1+(n-9)(-3)

Answers

Answer:

The correct answer is:

Option A. a_n=9+(n-1)(-3)

Step-by-step explanation:

Given that

a1 = 9

[tex]a_n = a_{n-1}-3[/tex]

We can see that in recursive formula the next term is being obtained by subtracting 3 from previous term

That means that the common difference is -3

We also know the first term

The general form of explicit formula for an arithmetic sequence is:

[tex]a_n = a_1 + (n-1)(d)[/tex]

We know that a1 = 9 and d = -3

Putting the values we get

[tex]a_n = 9+(n-1)(-3)[/tex]

Hence the correct answer is:

Option A. a_n=9+(n-1)(-3)

Sam had 1 1-2 m of rope. He cut off 5-8 m and used it for the project. How much does Sam have left​

Answers

1 1/2 m and 5/8 meter need to have the same denominator in order to subtract.

1 1/2 is equivalent to 12/8
Now 5/8 and 12/8 have the same denominator so you can subtract.
12/8-5/8= 7/8
7/8 m is left

In the scale used on a blueprint .1\4 inch represents 2 feet,on the blueprint what is the length of a room with an actual length of 20 feet?

Answers

Answer: The length of the room on blueprint = 10 feet.

Step-by-step explanation:

Given: On blueprint,

[tex]\dfrac14[/tex] inch = 2 feet

i.e. 1 actual feet = [tex]2\times\dfrac 14 =\dfrac12\text{ inch}[/tex]

If the actual length of 20 feet, the length of a room on blueprint = [tex]20\times\dfrac12\text{ feet}[/tex]

= 10 feet.

Hence, the length of the room on blueprint = 10 feet.
