Using the variable n for the term, describe the sequence.
Answer:
3 + 5n
Step-by-step explanation:
This is an arithmetic sequence.
First term = a = 8
Common difference = d =Second term - first term
= 13 - 8
= 5
Nth term = a + (n- 1)*d
= 8 + (n -1) * 5
= 8 + n*5 - 1 *5
= 8 + 5n - 5
= 8 - 5 + 5n
= 3 + 5n

Monica deposits $300 into a savings account that pays a simple interest rate of 4.2% paul deposits $400 into a savings account that pays a simple interest rate of 3.8% monica says that she will earn more interest in 1 year because her interest rate is higher is she correct?
Answer:
Paul earned $2.6 more interest than Monica.
Step-by-step explanation:
Giving the following information:
Monica:
Initial investment= $300
Interest rate= 4.2%
Paul:
Initial investment= $400
Interest rate= 3.8%
To calculate the income earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
Monica:
I= 300*0.042*1= $12.6
Paul:
I= 400*0.038*1= $15.2
Paul earned $2.6 more interest than Monica.

Angela is 4 feet 7 inches tall. Angela's doll is 11 inches tall. What is the ratio of Angela's height to the
doll's height?
Answer: 5:1 (simplified and in inches)
Step-by-step explanation:
Let’s convert Angelicas height in inches so all the measurements are the same.
Anglelicas height: 4 ft7 in
OR
Angelicas height: 55 inches
Dolls height: 11 inches
The ratio would be 55:11 but we would need to simplify since both numbers are divisible by a GCD (greatest common denominator)
55 and 11 are both divisible by 11 so the new simplified ratio would be...
5:1

Multiplying by which number is equivalent to an increase 49.5%
Answer:
22.46
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
49.5% = 49.5/100 = 49.5 ÷ 100 = 0.495.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 49.5% of its value.
Percentage increase = 49.5% × 22.46
New value = 22.46 + Percentage increase
In which of the following situations would finding the surface area of an object be the most applicable?
Hi, you've asked an incomplete question. However, I provided a brief explanation about surface areas.
Explanation:
Surface area is a term commonly used in mathematics, and other branches of science, and it basically refers to a calculation of the total space that an object occupies.
For example, you can find the surface areas of a cuboid using the formula:
[tex]6s^{2}[/tex] where s= side length.

For a regular polygon with 3 sides, each interior angle has a measure of-
A. 60
B.45
C.30
D.120
60
The sum of the interior angles of a triangle is 180
if there are 3 sides then there are 3 angles
180/3=60 so each interior angle has a measure of 60

A cone sits inside a cylinder, as shown. They share the same height and radius. What is the volume of the cylinder not taken up by the cone? Use 3.14 for p.
A
75.36 in.3
B
150.72 in.3
C
226.08 in.3
D
301.44 in.3
Answer:
Step-by-step explanation:
Volume of cylinder = πr²h
Volume of cone = πr²h/3
Volume of cylinder is not used by cone = ⅔πr²h = ⅔(3.14)(3^2)(8) = 150.72 sq in

Step-by-step explanation:
She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.
That means she walked 12 miles plus 1/4 of 12 miles.
She walked
12 + 1/4 * 12
You can factor out 12 from the expression above, and write it as
12(1 + 1/4)
Now you can do the addition in parentheses.
12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)
Answer:
C, D, F
Answer:
12 + 1/4 x 12, 12 x 5/4, and 12 (1 + 1/4)
Step-by-step explanation:
To solve this, you need to add 1/4 of 12 to 12. 1/4 of 12 is 3, and 12 + 3 is 15. All of these equations are equal to 15, therefore they are all correct.
1/4 x 12 = 3 + 12 = 15
12 x 5/4 = 60/4 = 15
1 + 1/4 = 5/4
5/4 x 12 = 60/4 = 15
