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.


find the equation of the line that is parallel y= 2x+10 and passes through the point (6,-4)

Answers

Answer:

The equation of the parallel line to the given line

y = 2 x - 16

Step-by-step explanation:

Step(i):-

Given equation of the straight line y = 2 x +10

                                             2x - y + 10 =0

The equation of the parallel line to the given line is

           a x + by + k=0

The equation of the parallel line to the given line is

           2x - y + k=0

Step(ii):-

Given point ( 6,-4)

The equation of the parallel line to the given line is

           2x - y + k=0

This line passing through the point ( 6,-4)

           2(6) - (-4)+ k=0

          12 + 4 +k =0

           16 + k=0

                k = -16

Final answer:-

The equation of the parallel line to the given line

y = 2 x - 16

Answer:11

Step-by-step explanation: think about 5+6 then when you add 11 to the -5 you get 6.

Answer:

The answer is -11.

Step-by-step explanation:

-11 + 6 equals -5.

This is because there is more negative than positive, so -11 would cancel out 6 positive, leaving behind 5 negatives.

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

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than twice the number
sent. How many were sent and how many were received each day?

Answers

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111      Eqn 1

y = 2x + 3     Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{108}{3}\\x = 36[/tex]

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75

Each of three friends—Lin, Jada, and Andre—had the goal of raising $40. How much money did each person raise?


Lin raised 100% of her goal.

Jada raised 50% of her goal.

Andre raised 150% of his goal.

Answers

Answer:

Down Below

Step-by-step explanation:

Lin: 100% of 40 = $40

Jada: 50% of 40 = $20

Andre: 150% of 40 = $60

The money raised by three friends is given below,

Lin raised 100% of her goal = $40

Jada raised 50% of her goal = $20

Andre raised 150% of his goal = $60

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Each of the three friends—Lin, Jada, and Andre—had the goal of raising $40.

The amount raised by all three friends will be calculated as,

Lin: 100% of 40 =40 x 1 =  $40

Jada: 50% of 40 = 40 x 0.5 = $20

Andre: 150% of 40 =40 x 1.5 = $60

Therefore, Lin raised 100% of her goal which is $40 Jada raised 50% of her goal which is $20 and  Andre raised 150% of his goal which is $60.

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)
