The circumference of a round pillow is 46.8 centimeters. Find the radius of the pillow, in centimeters. Round your
answer to the nearest tenth.
Answers
Answer:
7.5 centimeters
Step-by-step explanation:
The circumference is pi times the diameter
46.8/3.14=14.9
The radius is half of the diameter
14.9/2=7.45
7.45 is rounded to 7.5

After 4 years, $3,006 deposited in a savings account with simple interest had grown to a total of $3,967.92. What was the interest rate?
Answers
Answer:
So interest rate is 8% per annum
Step-by-step explanation:
Principal amount = $3,006
Amount at end = $3,967.92
Time = 4yrs
interest money = ($3967.92 - $3006)
also equal to = 4 * (x/100) * $3,006
Where x is the interest rate per annum
So, 4 * (x/100) * $3,006 = ($3967.92 - $3006)
x = 8%
So interest rate is 8% per annum
Jim began a 146-mile bicycle trip to build up stamina for a triathlete competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 5 hours. If Jim walks at a rate of 4 miles per hour and rides at 40 miles per hour, find the amount of time he spent on the bicycle.
Answers
Answer:
3.5 hours
Step-by-step explanation:
Let us represent
The time spent walking as x
The time spent riding as y
Jim began a 146-mile bicycle trip to build up stamina for a triathlete competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 5 hours.
Hence:
x + y = 5.... Equation 1
x = 5 - y
If Jim walks at a rate of 4 miles per hour and rides at 40 miles per hour,
The formula for Distance = Speed × time. Hence,
4 × x + 40 × y = 146 miles
4x + 40y = 146.... Equation 2
We substitute 5 - y for x in Equation 2
4(5 - y) + 40y = 146
20 - 4y + 40y = 146
Subtract 20 from both sides
20 - 20 - 4y + 40y = 146 - 20
- 4y + 40y = 146 - 20
36y = 126
y = 126/36
y = 3.5 hours
Since the time he spent raiding his bicycle is represented by "y", the amount of time he spent on the bicycle is 3.5 hours

In rhombus MNOP, side NO equals 45mm. What is the length of
OP
PM+MN
Answers
the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.
We are given a rhombus MNOP
We know that, a rhombus is a quadrilateral in which there are 4 sides and all the sides are equal.
We are given the length of the side NO as:
NO = 45 mm
Now, we need to find the length of side OP.
OP = 45 mm ( as NO = OP)
Also, we need to find PM + MN
PM + MN = NO + NO ( as PM = MN = NO )
= 2 NO
= 2 × 45 mm
= 90 mm
Therefore, we get that, the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.

The first term of a geometric sequence is 3 and the 4th is 1029. find the two terms between the 1st and the 4th.
Answers
Two terms between the 1st and the 4th in the given geometric sequence is 21 and 147.
The formula for the nth term in a geometric sequence is given by:
a(n) = a(1) . rⁿ⁻¹
Where:
a(1) = first term
r = common ratio
Parameters given:
a(1) = 3
a(4) = 1029
Substitute n = 4 into the formula:
a(n) = a(1) . rⁿ⁻¹
a(4) = 3 . r³
1029 = 3 . r³
r³ = 1029/3 = 343
r = 7
Two terms between the 1st and the 4th term is a(2) and a(3).
In a geometric sequence, the following applies:
a(n) = a(n-1) . r
Hence,
a(2) = 3 . r
= 3 . 7 = 21
a(3) = a(2) . r
= 21 . 7 = 147

Answers
Answer:36
Step-by-step explanation:
The required first and smallest term of consecutive terms is 38.
Given that,
The average of five consecutive numbers is 38. The smallest number to be determined.
The average of the values is the ratio of the total sum of values to the number of values.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
The average of five consecutive numbers is 38.
Let the middle value is a,
Series of 5 number can be given as = (a -2n) , (a-n) , a , (a+n) , (a+2n).
n = 5
Average = ( a-2n +a -n + a +a+n+ a+2n)/5
38 = 5a/5
a = 38
Now smallest and first term (n = 1) = a - 2n
= 38 - 2(1)
= 36
Thus, the required first and smallest term of consecutive terms is 38.

if a person is selected at random from this group of 1,000 people, determine the probability that he or she does not wear eyeglasses while driving even though he or she needs to wear it.
Answers
The probability is 7/5.
A person is randomly selected from a group of 1000 people.
We have,
440 people use glasses and must wear them.
20 wear glasses but are not required to do so.
140 people who should wear glasses but don't
400 if you don't need to wear glasses, don't wear them.
Therefore, the probability that the person does not wear glasses while driving even though he or she needs to wear them is:
P ( he or she does not wear glasses and needs to wear them / Total number of people surveyed ) = 140 / 100
P = 14 / 10
P = 7 / 5
The probability that he or she drives without wearing eyeglasses despite the fact that they are required is 7 in 5.
