11.70/65 = 0.18 or 18%
243^0.2x=81^x+5
Could you please help me with the steps to this problem?
Answer:
-20/3
Step-by-step explanation:
First simplify the left side of the equation
243^(1/5x)= (243^1/5)^x
=([tex]\sqrt[5]{243}[/tex] )^x
= 3^x
Now that the left side is simplified, let's move to the right side
81^(x+5)=( [tex]3^{4}[/tex])^(x+5) simplify 81 to base 3^4
=[tex]x^{4(x+5)[/tex] use the product of powers property to multiply the exponents together
=[tex]x^{4x+20[/tex]
With both sides simplified, let's rewrite the equation, this time in simplified terms
[tex]3^{x}[/tex]=[tex]3^{4x+20}[/tex]
x=4x+20 because both the bases are same, their exponential value must also be equal
-3x=20 solve the algebraic equation for x
x=[tex]-\frac{20}{3}[/tex]
Can Anyone please explain what linear equations are
Answer:
In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.

Find the median for the given set of data
⅝, ¾, 1⅛, 1¼
Answer:
15/16Step-by-step explanation:
Put the data in the ascending order, first bring to common denominator:
5/8, 3/4 = 6/8, 1 1/8 = 9/8, 1 1/4 = 5/4 = 10/85/8, 6/8, 9/8, 10/8Since the data is even the median is the average of 6/8 and 9/8:
(6 + 9)/8*1/2 = 15/16

1) Use the formula of rectangular prism: width x height x length
2) Use the formula of triangular prism: (Base x height x length) ÷ 2
3) Use the formula of cylinder: π x [tex]radius^{2}[/tex] x height
--------------------------------------------------------------------------------------------------
1)
width = 5 cmheight = 9 cmlength = 23 cmwidth x height x length
= 5 x 9 x 23

Solve for h.
h/6 − 1 = −3
h =
Answer:
[tex]h = - 12[/tex]
Step-by-step explanation:
1) Add 1 to both sides.
[tex] \frac{h}{6} = - 3 + 1[/tex]
2) Simplify -3 + 1 to -2.
[tex] \frac{h}{6} = - 2[/tex]
3) Multiply both sides by 6.
[tex]h = - 2 \times 6[/tex]
4) Simplify 2 × 6 to 12.
[tex]h = - 12[/tex]
Therefor, the answer is h = -12.
Answer:
h = - 12
Step-by-step explanation:
Add 1 to both sides of the equation
ℎ/6 − 1 + 1 = − 3 + 1
Simplify
ℎ/6 = − 3 + 1
h/6 = -2
Multiply all terms by the same value to eliminate fraction denominators
6 ⋅ ℎ/6 = 6 ( − 2 )
Cancel multiplied terms that are in the denominator
ℎ = 6 ( − 2 )
Multiply the numbers
ℎ = − 12

Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter
If the diameter of the circle below is 16 in., what is the area of the circle?
Answer:
64π inches² (approximately 201.06 inches²)
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius
To find the radius, divide the diameter by 2
16 ÷ 2 = 8 inches
Plug in 8 as the radius
[tex]A=\pi (8)^2\\A=64\pi[/tex]
[tex]A=201.06[/tex] (approximately)
Therefore, the area of the circle is 64π inches², or approximately 201.06 inches².
I hope this helps!
Answer:
201 inch²
Step-by-step explanation:
d=2r ⇔ 16=2r ⇔ r=8
A= Pi× r² ≈ 3.14 × 8² ≈ 201 inch²

Solve the system using elimination
Answer:
x = 5
y = 1/4
Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are
(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2
-10a - 16b = -66
-20b = - 80
b = 4 5a + 8(4) = 33
5a + 32 = 33
5a = 1
a = 1/5
a = 1/x = 1/(1/5) x = 5
b = 1/y = 4 y = 1/4
An expression is shown.
1 3/7 divided by 1 1/3
What is the value of the expression as a mixed number?
Answer:
1 ¹⁄₁₄
Step-by-step explanation:
[Step 1] [convert mixed fractions to improper fractions]
1 3/7 divided by 1 1/3 →
a b/c = b + a(c) / c = (b + ac) / c.
3 + 1(7) / 7 divided by 1 + 1(3) / 3 →
10 / 7 divided by 4 / 3.
[Step 2] [flip the numerator and denominator(take the reciprocal) of the fraction you are dividing by and multiply]
10 / 7 divided by 4 / 3 →
a / b → b / a = 1 / (a / b) = (a / b) ^ -1.
10 / 7 multiplied by (3 / 4).
When you multiply 2 fractions, you multiply across. Numerator × Numerator / Denominator × Denominator.
a / b × c / d = (a × c) / (b × d).
10 / 7 multiplied by (3 / 4) →
10 / 7 × 3 / 4 →
(10 × 3) / (7 × 4) →
30 / 28.
[Reduce completely until the denominator or numerator is prime or can only be divided by one and itself to remain an integer]
30 / 28 →
15 / 14.
[Find the difference between the numerator and denominator and that will be the numerator of the mixed fraction or the remainder, the denominator will be the same denominator of the improper fraction and the whole part will be how many times the denominator can fit in the numerator of the improper fraction]
[Or you can do long division and you will add the quotient (top number above long division bar) and the remainder.]
a / b = (# times b fits into a) + (remainder / b).
15 / 14 = (# times 14 fits into 15) + (1 / 14).
15 / 14 = 1 + (1 / 14)
15 / 14 = 1 ¹⁄₁₄
