Answer:
-99/20 or -4.95
Step-by-step explanation:
make the first fraction a simple fraction by multiplying the denominator by the whole number and adding the numerator.
which equals 11/5. Then you multiple by the reciprocal of 4/-9 which is -9/4
to look like 11/5 * -9/4 = -99/20

A spinner has six sections: two sections are labeled a comma two sections are labeled B, and two sections are labeled see?
a. what is the sample space for the spinner?
b. what is the probability of spinning and landing on it?
Answers
Answer:
Step-by-step explanation:
a. The sample space for this spinner would be A, B or C . Since these are the only possible outcomes in this specific spinner.
b. The spinner has a total of 6 sections but each letter has 2 sections dedicated to it. Therefore, this makes only 3 possible outcomes in which the spinner will only land on 1. This means that the probability of each letter would be 1/3

Answers
Answer:
4y - 3x = -25
Step-by-step explanation:
The equation of a line in point-slope form is expressed as
y - y0 = m(x - x0)
(x0, y0) is the point
m is the slope
Given
(x0, y0) = (3, -4)
Also given the equation;
8x + 6y = 15
Rewrite in standard form;
6y = -8x+15
y = -8/6 x + 15/6
y = -4/3 x + 5/2
Slope m = -4/3
Since the required line is perpendicular to the given line =,
Slope = -1/(-4/3) = 3/4
Substitute into the formula;
y - (-4) = 3/4(x-3)
y + 4 = 3/4(x-3)
4(y+4) = 3(x-3)
4y + 16 = 3x - 9
4y - 3x = -9-16
4y - 3x = -25
This gives the required equation

Answer:
x = [tex]\frac{83}{36}[/tex]
Step-by-step explanation:
Given
x - 2 [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{18}[/tex] ( change mixed number to improper fraction )
x - [tex]\frac{9}{4}[/tex] = [tex]\frac{1}{18}[/tex]
Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions
36x - 81 = 2 ( add 81 to both sides )
36x = 83 ( divide both sides by 36 )
x = [tex]\frac{83}{36}[/tex]

Step-by-step explanation:
There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.
4+2+3 = 9
Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.
You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.
You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.

The width of a rectangle measures (3s+t) centimeters,and it’s length measures (3s-9t) centimeters. Which expression represents the perimeter,in centimeters of the rectangle ?
Answers
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.

Answers
Hi there! Given the equation below.
[tex] \large{r + \sqrt{x} = 9}[/tex]
First is to subtract both sides by r-term to isolate x-term.
[tex] \large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}[/tex]
Because the x-term is in square root form. We have to square both sides to get rid of the square root.

Answer:
y = x²+8x+7
Step-by-step explanation:
according to the table, we get the point :
(-4, -9) as the vertex and (0, 7) as y-intercept
y = ax²+bx+c
=> the symetry axis :
x = -b/2a = -4
b=-4×2a = 8a
let a=1, => b = 8(1) = 8
y-intercept = (0, c) =(0, 7) => c =7
so, the equation might be :

9. How much greater is 0.05723 than 0.005? ?
Answers
Answer:
0.05223
Step-by-step explanation:
0.05723 is 0.05223 greater than 0.005.
What is decimal?
A decimal number is one in which the whole number component and the fractional component are separated by a decimal point. The decimal point is the dot seen in decimal numbers. The decimal point is followed by digits that represent a number less than one.
As an illustration, consider the decimal value 17.48, where 17 is the entire integer and 48 is the decimal portion.
When is some number greater?When one number exceeds another, the phrase "more than" is used. Even greater than is utilised to compare the two weights.
How to solve it?
Take the difference
0.05723-0.005=0.05223
Hence, 0.05723 is 0.05223 greater than 0.005.

Given:
Diameter of sphere = 4.4 centimeter
Value of π = 3.14
Find:
Volume of sphere
Computation:
Radius of sphere = Diameter of sphere / 2
Radius of sphere = 4.4 / 2
Radius of sphere = 2.2 centimeter
Volume of sphere = [4/3][π][r³]
Volume of sphere = [4/3][3.14][2.2³]
Volume of sphere = [4/3][3.14][10.648]

The opposite of a function is its inverse
The ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)
From the function, we have the following ordered pairs
(x,y) = (4,-2), (-2,-2), (-1,-2)
The inverse of a function (x,y) is (y,x).
So, we have:
(y,x) = (-2,4), (-2,-2), (-2,-1)
Hence, the ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)

Lamar made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $43.80If the beads cost $3.80 for each necklace, how much did each pendant cost?
Answers
Answer:
3.50
Step-by-step explanation:
Necklace has beads and a pendant
b +p
There are 6 necklaces at a cost pf 43.80
6(b+p) =43.80
The beads for one necklace cost 3.80 so replace b with 3.80
6(3.80+p) =43.80
Divide each side by 6
6(3.80+p)/6 =43.80/6
3.80 +p = 7.30
Subtract 3.80 from each side
3.80+p-3.80 = 7.30 -3.80
p =3.50
