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

What is 20% of 50 and what would 10% equal
Answer:
20/100 x 50 is 10
10% would be 10/100 is fraction form
I want to help you on the first thing you said,
so always consider a percent as a fraction but there denominator is ALWAYS 100 (a way to remember that is that the word "cent" means 100). The word "of" means multiplication so that means your multiplying it with 50 and just do the multiplication.
I'm really hoping you understand!

A fair dice has 6 sides numbered 1 to 6. After it is rolled, 5 of the numbers can be seen. What is the probability that one of these numbers is a 3
Answer:
[tex] \frac{5}{6} [/tex]
Step-by-step explanation:
Out of those 5 sides, we need to be able to see a 3 from a 6 sided dice.
The total will always be your demoninator and since we was looking at sides, we just need a side that has a 3.

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
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

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

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.

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
