A. $19.05
B. $24.00
C. $19.95
D. $18.05
Answer:
C.
Step-by-step explanation:

0.95 + 19 = 19.95
answer is C. 19.95
solve the equation -8=7x+2/5
Answer:
-6/5 = x
Step-by-step explanation:
Multiply by 5 to get rid of fractions:
-40 = 35x + 2
Subtract by 2 to get all terms on one side:
-42 = 35x
Divide by 35 to get x term:
-42/35 = x

Find the 4th term of the geometric sequence whose first term is 3 and common ratio is 2.
The 4th term of the geometric sequence whose first term is 3 and the common ratio is 2 is 24.
What is a geometric sequence and how to find its nth terms?Suppose the initial term of a geometric sequence is a
and the term by which we multiply the previous term to get the next term is r then the sequence would look like
a, ar, ar², ar³,...., arⁿ
Thus, the nth term of such sequence would be aₙ = a₁ × r⁽ⁿ⁻¹⁾ (you can easily predict this formula, as for the nth term, the multiple r would've multiplied with initial terms n-1 times).
Given the first term of the sequence is 3, while the common ratio is 2, therefore, the fourth term of the geometric sequence can be written as,
aₙ = a₁ × r⁽ⁿ⁻¹⁾
a₄ = 3 × 2⁽⁴⁻¹⁾
a₄ = 3 × 2³
a₄ = 24
Hence, the 4th term of the geometric sequence whose first term is 3 and the common ratio is 2 is 24.

write 28% as a fraction
Answer:
28% as a fraction can be written in many ways. The most simplest way to convert a percentage to a fraction would just to put it over 100. For example, 50% would be 50/100 therefore 28% would be 28/100.
However, we can simplify that fraction even more by doing (28/4)/(100/4) which would give us 7/25.

The formula to convert Celsius to Fahrenheit is
[tex]^oC=\dfrac{5}{9}(^oF-32)[/tex]
Now, there is no data given in the problem. Thus, the above formula for any data can be used to convert the unit of temperature measurement.

Are the triangles similar?
Answer:
No, because the sides lengths are not proportional.
Step-by-step explanation:
What is the SAS similarity theorem ?By definition, two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional.
What is the AA similarity theorem ?If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.
They both have an angle of 70°This lies between sides of 6/9 and 9/18 respectively for the triangles6/9 = 2/3 and 9/18 = 1/2Hence, the sides are not proportionalThey are not similarWhich of the following is the correct factorization of the polynomial below?
Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse A B is 26, the length of A C is 10, and the length of B C is 24.
Given right triangle ABC, what is the value of tan(A)?
Answer:
tan(A) = 12/5Step-by-step explanation:
Given a right angle triangle ABC.
If ∠BCA = 90°
the hypotenuse AB = 26
AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
Answer:
[tex]\ tan \ A = \dfrac{24}{10}[/tex]
Step-by-step explanation:
[tex]\sf Tan \ A = \dfrac{opposite \ side \ of \ angle \ A}{adjacent \ side \ of \ angle A}\\\\Tan \ A = \dfrac{BC}{AC}\\\\Tan \ A = \dfrac{24}{10}[/tex]

From each square we can construct a second square, whose area is double that of the first square.
Construct from the square abcd below a second square, whose area is double the area of the square abcd.
Answer:
So the first thought would be to make the length and width twice the size of the original square but this would actually cause us to multiply the area by 4.
The second thought was to raise one of the sides to be twice the length or width and that would give us the correct answer since we are just multiplying it by 2. If side AB is the only one that can move then we would just extend that side twice the original length.

PLEASE HELP!!!!!!! IMA DESPRATE!!!!!!! A radioactive isotope decays exponentially. The time it takes for half of the amount to decay is called the isotope's half-life. If an isotope has a half-life of 16 hours and you initially have 154 mg, how much will you have left after 64 hours? Round to the nearest thousandth.
Since the isotope is initially 154 mg, the amount of radioactive isotope left after 64 hours is 9.625 mg
To answer the question, we need to know what radioactive decay is.
What is radoactive decay?Radioactive decay is the spontaneous disintegration of a larger atom to a smaller one
What is half-life?Half-life of a radioactive isotope is the time it takes for the isotope to decay to half its initial value.
Amount left after n half livesThe amount left after n half lives is N = (1/2)ⁿN₀ where N₀ = initial mass of isotope.
Given that the half-life of the isotope is 16 hours, and we desire the amount present after 64 hours.
The number of half-lives after 64 hours is n = time/half-life
= 64 h/16 h
= 4
Since we have 154 mg of isotope present, N₀ = 154 mg
Given that
n = 4 and N₀ = 154 mgSubstituting the values of the variables into N, we have
N = (1/2)ⁿN₀
N = (1/2)⁴ × 154 mg
N = 154 mg/16
N = 9.625 mg
So, the amount of radioactive isotope left after 64 hours is 9.625 mg
