Step-by-step explanation:
-9.5x-1.5>-30
Hello There!
So once again we want to isolate the variable using inverse operations
To get rid of the 1.5 we add 1.5 to each side
-1.5+1.5 cancels out
-30+1.5=-28.5
now we have
-9.5x>-28.5
to get rid of the -9.5 we divide each side by -9.5
-9.5x/-9.5=x
-28.5/-9.5=3
Remember we are dividing by a negative number so we have to flip the inequality sign
We're left with

2. Ronu's present age is "x “years and her sister Shaani's present age is twice
of Ronu's age. Write following as algebraic expression
a) Ronu's present age
b) Ronu's age after 2 years
c) Shaani's present age
d) Shaani's age after 2 years
What hould be added to 100 to get - 132
Answer:
x = -232
Step-by-step explanation:
Ronu's present age is "x “years and her sister Shaani's present age is twice of Ronu's age.
(a) Ronu's present age = x years
(b) Ronu's age after 2 years = (x+2) years
(c) Shaani's present age = 2x years
(d) Shaani's age after 2 years = (2x+2) years
Let x should be added to 100 to get -132.
x+100 = -132
x = -100-132
x = -232
Hence, -232 must be added to 100 to get -132.

d. 105
9514 1404 393
Answer:
b. -75°
Step-by-step explanation:
Point A moves from (-4, -3) to (-4, 3). We can find the angle of rotation several ways. One is to consider the tangent of the angle relative to the x-axis.
Point A is on a line that makes an angle to the x-axis of ...
∠A = arctan(-3/-4) = 36.9°
Point A' is on a line that makes an angle to the x-axis of ...
∠A' = arctan(3/-4) = -36.9°
Then the change in angle is ...
∠A' -∠A = -36.9° -36.9° = -73.8°
The closest answer choice is ...
b. -75°
The width of a rectangular table is 2.3 feet less than its length. If the area of the table is 9.5 square feet, find its dimensions.
Answer: Width = 12 feet
length = 9 feet
The dimensions of the rectangular table are approximately 5.77 feet by 3.47 feet.
Let's denote the length of the rectangular table as L.
According to the given information, the width is 2.3 feet less than the length. Therefore, the width can be expressed as L - 2.3.
The area of a rectangle is calculated by multiplying its length by its width. In this case, the area is given as 9.5 square feet.
So, we have the equation:
Length * Width = Area
L * (L - 2.3) = 9.5
Expanding the equation:
L² - 2.3L = 9.5
Rearranging the equation:
L² - 2.3L - 9.5 = 0
To solve this quadratic equation, we can use the quadratic formula:
L = (-b ± √(b² - 4ac)) / (2a)
For this equation, a = 1, b = -2.3, and c = -9.5.
Substituting the values into the quadratic formula, we get:
L = (-(-2.3) ± √((-2.3)² - 4 * 1 * (-9.5))) / (2 * 1)
L = (2.3 ± √(5.29 + 38)) / 2
L = (2.3 ± √43.29) / 2
Calculating the square root and simplifying further, we find two possible values for L:
L ≈ 5.77 or L ≈ -3.07
Since length cannot be negative, we discard the negative solution.
Therefore, the length of the rectangular table is approximately 5.77 feet.
To find the width, we substitute this value back into the equation for the width:
Width = Length - 2.3
Width ≈ 5.77 - 2.3
Width ≈ 3.47 feet
So, the dimensions of the rectangular table are approximately 5.77 feet by 3.47 feet.

What is the 7th term in the sequence?
Answer:
[tex]T_7 = 136.6875[/tex]
Step-by-step explanation:
Given
12, 18, 27, ..
Required
Determine the 7th term
The above sequence shows a geometric sequence and the nth term is calculated by:
[tex]T_n = a * r^{n-1[/tex]
r is calculated by:
[tex]r = \frac{T_2}{T_1}[/tex]
[tex]r = \frac{18}{12}[/tex]
[tex]r = 1.5[/tex]
[tex]a = 12[/tex] --- First term
[tex]n = 7[/tex]
So:
[tex]T_n = a * r^{n-1}[/tex]
[tex]T_7 = 12 * 1.5^{7-1[/tex]
[tex]T_7 = 12 * 1.5^6[/tex]
[tex]T_7 = 136.6875[/tex]
