Express 4.9 (bar only on 9)in the form of p/q
Answer:
4/9 is the answer for this question
Step-by-step explanation:
Answer:
Step-by-step explanation:
x = 4.999.... ---------(I)
After decimal point only one digit is repeating. So multiply both sides by 10
10x = 49.999.....(II)
subtract (I) from (II)
10x = 49.999...
x = 4.999.... {subtract}
9x = 45
x = 45/9
x = 5/1

The volume of a box(v) varies directly with its length(l). If a box in the group has a length of 35 inches and k=15, what is its volume?
Answer:
525 in³
Step-by-step explanation:
Use the direct variation equation, y = kx.
Substitute y with v (volume) and substitute x with l (length) to represent this situation:
y = kx
v = kl
Plug in 35 as l and 15 as k, then solve for v (the volume):
v = kl
v = 15(35)
v = 525
So, the volume of the box is 525 in³

Find the coordinates of the missing endpoint if E is the midpoint of DF.
D(-3,-8), E(1,-2)
Answer:
F(5;4)
Step-by-step explanation:
Call F(x;y)
cuz E is the midpoint so we have a formula:
(-3+x)/2=1 -> x=5
(-8+y)/2=-2 -> y= 4
so F(5;4)
Please help explanation if possible
Answer:
Step-by-step explanation:
The equation for the direct variation is, for us (using f and m instead of y and x):
f = km, where k is the constant of proportionality. We need to solve for this first using the first set of given values:
-19 = k(14) so
[tex]k=-\frac{19}{14}[/tex] Now plug that in with second set of givens, namely to find f when m is 2:
[tex]f=(-\frac{19}{14})(2)[/tex] and
[tex]f=-\frac{19}{7}[/tex]

The present age of Madison's Mother is 3 time that of Madison. After 6 1/4 years, the sum of their age will be 53 3/4 years. Find their present ages. (Estimate to the nearest whole number)
Answer: [tex]10, 31\ \text{years}[/tex]
Step-by-step explanation:
Given
The present age of Madison's Mother is three time that of Madison
Suppose the Present age of Madison is [tex]x[/tex], so age of her mother is [tex]3x[/tex]
After [tex]6\dfrac{1}{4}\ \text{years}[/tex], the sum of their age will be [tex]53\dfrac{3}{4}\ \text{years}[/tex]
[tex]\therefore (x+6\dfrac{1}{4})+(3x+6\dfrac{1}{4})=53\dfrac{3}{4}\\\\\Rightarrow 4x+2\times \dfrac{25}{4}=\dfrac{53\times 4+3}{4}\\\\\Rightarrow 4x+\dfrac{50}{4}=\dfrac{215}{4}\\\\\Rightarrow 4x=\dfrac{215-50}{4}\\\\\Rightarrow x=\dfrac{165}{16}\\\\\Rightarrow x= 10.31\approx 10[/tex]
Madison mother's age [tex]3x=30.93\approx 31\ \text{years}[/tex]
When a sprinkler is installed in the ground, the spray of water goes up and falls in the pattern of a parabola. The height, in inches, of a spray of water is given by the equation h(x)=160x−16x2 where x is the number of feet away from the sprinkler head the spray is. What is the height of the spray 2 feet away from the sprinkler head?
Answer:
(1) 256 inches
(2) 5 feet
(3) 400 inches
(4) 10 feet
Step-by-step explanation:
(1) The function that gives the height in inches of the spray of water at a distance x from the sprinkler head is given as follows;
h(x) = 160·x - 16·x²
At x = 2 feet, we have;
h(2) = 160 × 2 - 16 × 2² = 256
Therefore, the height of the spray water at a horizontal distance of 2 feet from the sprinkler head h(2) = 256 inches
(2) The x-coordinate, [tex]x_{max}[/tex], of the maximum point of a parabola given in the form, y = a·x² + b·x + c is found using the following formula;
[tex]x_{max}[/tex] = -b/(2·a)
The x-coordinate, [tex]x_{max}[/tex], of the maximum point of the given equation of the parabola, h(x) = 160·x - 16·x², (a = -16, b = 160) is therefore;
[tex]x_{max}[/tex] = -160/(2 × (-16)) = 5
Therefore, the number of feet along the way, the function will reach maximum height, [tex]x_{max}[/tex] = 5 feet
(3) The function, h(x) = 160·x - 16·x², will reach maximum height, [tex]h_{max}[/tex], at x = 5, therefore;
[tex]h_{max}[/tex] = h(5) = 160 × 5 - 16 × 5² = 400
The maximum height of the spray, [tex]h_{max}[/tex] = 400 inches
(4) The water is at ground level where h(x) = 0, therefore;
At ground level, h(x) = 0 = 160·x - 16·x²
160·x - 16·x² = 0
∴ 16·x × (10 - x) = 0
By zero product rule, we 16·x = 0, or (10 - x) = 0, from which we have;
x = 0, or x = 10
The water is at ground level at x = 0 and x = 10 feet, therefore, the water will hit the ground again (the second time after leaving the sprinkler head at x = 0) at x = 10 feet.
1. Find the probability of picking a yellow marble and an orange
marble when 2 marbles are picked (without replacement)
from a bag containing 2 yellow and 4 orange marbles
Answer:
4/15
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the bag contains 2 yellow and 4 orange marbles, the probability of picking a
Yellow marble = 2/(2+4) = 2/6
Orange marble = 4/(2+4) = 4/6
The probability of picking a yellow marble and an orange marble without replacement
= 2/6 * 4/5
= 8/30
= 4/15

Describe the location of point (-3, -2, 3) in three-dimensional coordinate space.
Answer:
The usual way to draw a 3-D grid can be seen below.
The positive z-axis points upwards
The positive y-axis points to the right
The positive x-axis points towards you, or to the front.
And the notation for a point in 3-D is (x, y, z)
In this case, our point is (-3, -2, 3)
Then the location of the point can be described as:
So the x-value is -3, which means that the point is 3 units behind the origin.
The y-value is -2, which means that the point is 2 units at the left of the origin
The z-value is 3, which means that the point is 3 units above the origin.

how many five digit numbers can be created using the digits 2 3 4 7 8 and 9 without repeating any digits in the five digit number
Answer:
6*5*4*3*2*1 = 6! = 720
Step-by-step explanation:
There are 720 three digit numbers that can be created from the digits provided given that no digit may be repeated.
What is a permutation?A permutation is defined as a mathematical process which determines the number of different arrangements in a set of objects when the order of the sequential arrangements.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
There are six choices to begin with and that quantity decreases by one every time the next digit is chosen as shown below:
⇒ 6*5*4*3*2*1
⇒ 6!
⇒ 720
Hence, there are 720 three digit numbers that can be created from the digits provided given that no digit may be repeated.

Finding an irrational number between which given pair of numbers supports the idea that irrational numbers are dense in real numbers? 3.14 and pi 3.33 and 1/3 e squared and square root of 5 square root of 64 over 2 and square root of 16
Answer:
So, we need to find irrational numbers between the given pairs.
Remember that the sum between an irrational number and an rational number is irrational.
For example, for the first case, we want a irrational number between:
3.14 and pi:
pi = 3.14159265.... is irrational
pi - 0.0001 = 3.14159265... - 0.0001 = 3.14149265...
So this number:
3.14149265...
is an irrational number larger than 3.14 and smaller than pi.
Second cacse:
3.33 and 1/3
(here the range would be actually:
1/3 = 0.33 and 3.33
So we want an irrational number larger tan 0.33 and smaller than 3.33
here we can just use pi = 3.141592...
third case:
e^2 and √5
Firs let's write these numbers so we can see how they look.
e^2 =7.389...
√5 = 2.236
So we want a number larger than 2.236... and smaller than 7.389...
Again, here we can use pi = 3.141592...
2.236... < 3.141592... < 7.389...
final case:
√(64/2) and √16
we have:
√(64/2) = 5.65
√16 = 4
So we want an irrational number larger than 4 and smaller than 5.65
Again, let's use our beloved number pi.
we have that:
pi + 1 is an irrational number:
pi + 1 = 3.14159265... + 1.0 = 4.14159265....
This number, 4.14159265..., is irrational, is larger than 4 and is smaller than 5.65, so we found the irrational number between the given pair of numbers.

Answer:
4π inches
Step-by-step explanation:
Formula for finding length of arc AB = θ/360*2πr
Where,
Central angle (θ) = 120°
Radius (r) = 6 inches
Length of arc AB = 120/360*2*π*6
Length for arc AB = ⅓*12π
= 4π inches
