Answer:
Option D
Step-by-step explanation:
Fractions are considered to be rational numbers because they are decimals that can be written as a fraction and since it's already wrote as a fraction but can be converted back to a decimal it is a rational number. The fraction is considered to be a real number because all rational numbers are real numbers and since we just proved that 5/8 is a rational number it is therefore a real number. Which means your answer is option D or "rational numbers, real numbers."
Hope this helps.

Answer:
∅ = 22.33°
Step-by-step explanation:
tan 28° = h/15
0.5317 = h/15
h = 7.98
sin ∅ = h/21
sin ∅ = 7.98/21
sin ∅ = 0.38
∅ = 22.33°

Anil scored 30 runs in the first innings of a test match. His score changed by +30 runs in the second innings. What was his score in the second innings?
Answer:
60 runs
Step-by-step explanation:
Given that:
Score in first innings = 30 runs
Change in score during second inning = + 30
The score in the second inning will be :
Score in first inning + change in score during second inning
30 + (+30)
30 + 30
= 60 runs

the perimeter of a rectangular garden used 86 feet of barbed wire. The length of the garden is 7 feet more than its width. Find the dimensions of the garden.
answer with solution?
Answer:
Step-by-step explanation:
perimeter of a rectangle = twice the length plus twice the width
P = 2L + 2W equation 1 P = 86 ft
Given the length is seven feet more than the width
L = W + 7 equation 2
Substitute equation 2 into equation 1
P = 2(W+7) + 2W = 86 ft
2W +14 + 2W = 86 ft
4W = 86 - 14
W = 72 / 4
W = 18 feet

Why am i wrong? Trigonometric Ratios. Real answers only!
Answer:
You may have gotten the opposite and adjacent mixed up.
[tex]\frac{24}{7}[/tex]
Step-by-step explanation:
An easy way to remember these trigonometric ratios is by using SOHCAHTOA, where:
SOH stands for-
[tex]Sine=\frac{Opposite}{Hypotenuse}[/tex]
CAH stands for-
[tex]Cosine=\frac{Adjacent}{Hypotenuse}[/tex]
TOA stands for-
[tex]Tangent=\frac{Opposite}{Adjacent}[/tex]
We are asked to find tan 74° given the right triangle. To find this, we must find the lengths of the opposite side and the adjacent side of the 74° angle. From looking at the triangle, we can see that the side opposite from the 74° angle is 24, and the adjacent is 7. So plugging it into the trigonometric ratio that we found using SOHCAHTOA, we find that:
[tex]tan74=\frac{24}{7}[/tex]
So the answer would be [tex]\frac{24}{7}[/tex]
Seeing as how you picked [tex]\frac{7}{24}[/tex] as your answer, it seems that you may have gotten the opposite and the adjacent mixed up or used [tex]tangent=\frac{adjacent}{opposite}[/tex] as your trigonometric ratio.
I hope you find my answer and explanation to be helpful. Happy studying.
vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his uncle.what are the ages of vamis brother, uncle and aunt? what will be the age of his uncle 6 years from now
pls send the ans fast
Step-by-step explanation:
Vamsi is X years old
Vamsi = X
his brother is 3 years elder to him
Brother = X + 3
his uncle is 4 times his age
Uncle = 4X
his aunt is 5 years younger than his uncle
Aunt = Uncle - 5
what will be the age of his uncle 6 years from now
= 4X + 6
what are the ages of vamis brother, uncle and aunt?
Assume Vamis = 15 years
Brother = X + 3 = 15 + 3 = 18
Uncle = 4X = 4 * 15 = 60
Aunt = Uncle - 5 = 60 - 5 = 55
what will be the age of his uncle 6 years from now
Uncle = 4X + 6 = 60 + 6 = 66
An isotope of cesium-137 has a half-life of 30 years. If 5.5 grams of cesium-137 disintigrates over a period of 105 years, how many grams of cesium-137 would remain? Round your answer to the thousandths place.
Answer:
0.484 g
Step-by-step explanation:
N/No = (1/2)^t/t1/2
No = mass of cesium-137 originally present
N= mass of cesium-137 at time t
t1/2= half life of cesium-137
t = time taken
N/5.5=(1/2)^105/30
N/5.5=(1/2)^3.5
N/5.5= 0.088
N = 5.5 * 0.088
N= 0.484 g

Answer:
1120 in.³
Step-by-step explanation:
The formula for Volume is V = l*w*h
In this case it would be V = 8*14*10
14*10=140
140*8 = 1120
Therefore, the correct answer would be 1120 in.³

Answer:
x = 7x = 4x = 5x = 2Step-by-step explanation:
The general steps are ...
look at what you haverewrite the equation so the variable terms are on one side and the constant terms are on the other side of the equal sign; collect termsdivide by the coefficient of the variableIt is generally convenient to put the variable terms on the side of the equation having the largest (most positive) variable term. You do the rearranging by subtracting the terms you don't want. Any operation is performed on both sides of the equation.
__
1) 3x + 7 = 4x
We observe the largest x-term is on the right, and the only constant term is on the left. We can subtract the x-term 3x to eliminate it from the left side
3x +7 -3x = 4x -3x
Combining like terms gives ...
7 = x . . . . . this is the solution
__
2) x +2 +2x = x + 10
We observe x-terms and constants on both sides of the equation. First of all, we will combine like terms.
3x +2 = x +10
The largest x-term is on the left, so we choose to subtract x (the x-term on the right)
3x -x +2 = x -x +10
2x +2 = 10
We don't want the constant on the left, so we subtract 2.
2x +2 -2 = 10 -2
2x = 8 . . . . . . . . . . combine like terms
Now, we divide by the coefficient of x.
2x/2 = 8/2
x = 4 . . . . . . the solution
__
3) x +3x = x + x + 10
4x = 2x +10 . . . . . . . combine like terms
2x = 10 . . . . . . . . . . . subtract 2x
x = 5 . . . . . . . . . . . . . divide by 2
__
4) 2x +3 + 3x = x + 11
5x +3 = x +11 . . . . . . . . combine like terms
4x +3 = 11 . . . . . . . . . . . subtract x
4x = 8 . . . . . . . . . . . . . . subtract 3
x = 2 . . . . . . . . . . . . . . .divide by 4
_____
Learn to identify and combine like terms. Use addition or subtraction to eliminate terms you don't want. Use multiplication or division to eliminate coefficients you don't want. Whatever you do to one side of the equation must also be done to the other side of the equation. (In the above, we use "subtract ..." to mean "subtract ... from both sides of the equation," for example.)
