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)

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.
