Answer:
The archaeologists dis not actually discovered the lost temple
Step-by-step explanation:
For us to be able to determine if the archaeologist actually discovered the lost temple, we need to find the dimension of the temple first.
Area of the temple = LW
Perimeter = 2L + 2W
L is the length
W is the width
If the perimeter is 220m
220 = 2L + 2W
110 = L+W ... 1
If the area is 2100 square meters
A = LW
2100 = LW ... 2
From 1;
L = 110 - W .... 3
Substitute 3 into 2
From 2;
2100 = LW
2100 = (110-W)W
2100 = 110W - W²
- W² + 110W - 2100 = 0
W² - 110W + 2100 = 0
Using the general formula;
W = -(-110)±√(-110)²-4(1)(2100)/2
W = 110±√3700/2
W = 110±60.83/2
W = 110±60.83/2
W = 110+60.83/2 and W = 110-60.83/2
W = 170.83/2 and 49.17/2
W = 85.415m and 24.585m
Substitute the width into the formula to get the length;
LW = 2100
L = 2100/W
L = 2100/85.415
L = 24.59 m
If the width is 24.585m;
L = 2100/24.585
L = 85.42m
Since we have different dimension of the temple, this show shat the archaeologists dis not actually discovered the lost temple

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?
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

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes

The first term of a geometric sequence is 3 and the 4th is 1029. find the two terms between the 1st and the 4th.
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

The average of five consecutive numbers is 38. What is the smallest
number?
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.
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.

In rhombus MNOP, side NO equals 45mm. What is the length of
OP
PM+MN
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.
