Answer:
26x2,
52xπ
Step-by-step explanation:
The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.
What is the circumference of a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let 'r' be the radius of the circle. The circumference of the circle will be
C = 2πr units
The radius of the semicircle is given as,
r = 26 cm
Then the circumference of the semicircle is half of the circle. Then we have
C = 1/2 x 2πr
C = πr
At r = 26 cm, then we have
C = 3.14 x 26
C = 81.64 cm
The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.

How can percents show proportional relationships between
quantities and be used to solve problems?
Answer:
By testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin
Step-by-step explanation:
Percentages are simply the measures of a quantity over a hundred (100), while proportional relationships are relationships that have a constant equivalent ratio
Solving proportional relationships using percentage
A proportional relationship is represented as:
[tex]y = kx[/tex]
Where k represents the proportionality constant, and x and y are the variables (or quantities).
Using percentages, then k has to be represented as a percentage.
Take for instance,
20 is 5% of 1007 is 5% of 140When the above instance are represented as a proportional relationship, we have:
[tex]y = 5\% \times x[/tex]
Such that
[tex]k = 5\%[/tex]

Taylor has dd dimes and qq quarters. She has a maximum of $4 worth of coins altogether. Write this situation as an inequality.
Answer: .10d+.25q<_ 4
Step-by-step explanation:
d= dimes and q = quarters
dimes are worth .10 and quarters are worth .25
The inequality for the given situation is
0.1d + 0.251 ≤ 4
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
10 dimes = 1 dollar
1 dime = 0.1 dollar
4 quarters = 1 dollar
1 quarter = 0.25 dollar
Now,
The maximum amount is $4.
So,
0.1d + 0.251 ≤ 4
Thus,
The inequality is 0.1d + 0.251 ≤ 4.

What is the answer ??
UD = ?
Answer:
UD = 20
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
12² = 7.2(7.2 + CD)
144 = 7.2² + 7.2CD
144 = 51.84 + 7.2CD ( subtract 51.84 from both sides )
92.16 = 7.2CD ( divide both sides by CD )
12.8 = CD
Thus
UD = UC + CD = 7.2 + 12.8 = 20

.Sally is comparing 2 types of house insurance. Both companies provide the same service; however,
CarHelp is quoting $8.60 per week where as CarSafety is quoting $36.10 per month. Which
company should Sally go with if she wishes to choose the cheapest?

In order to determine which type of house insurance would be considered as cheapest first it is necessary to determine either monthly or either weekly
As we know that
Generally in the month there is a 4 weeks
So For Car Help, the monthly would be
= $8.60 × 4
= $34.40
And for Car safety, the quoted price is $36.10 per week
So according to the above calculation the car help would be choose as the cheapest

Write an equation to fond the nth term of each sequence. Then find a9. 5,20,80
Answer: a₉ = 327,680
Step-by-step explanation:
This seems to be a geometric sequence.
The recursive relation for this type of sequence is:
aₙ = aₙ₋₁*r
Where r is a constant.
Then we also have:
aₙ/aₙ₋₁ = r.
then we can find the value of r if we take the quotient of different consecutive terms, for example, the quotient of the second and firs term is:
r = 20/5 = 4
And the quotient between the third and second term is:
r = 80/20 = 4
Then we can conclude that r = 4.
And also, the n-th term of this sequence can be written as:
aₙ = a₁*r^(n - 1)
such that:
a₁ = 5
r = 4
Then the n-th term of this sequence is:
aₙ = 5*(4)^(n - 1)
Then the term a₉ can be found if we just replace n by 9 in the above equation:
a₉ = 5*(4)^(9 - 1) = 5*(4)^(8) = 327,580
