Answer:
The possible values of x are ±8 sqrt(2)
Step-by-step explanation:
To find the value of x, we find the geometric mean
sqrt(32*4 )= sqrt(128) = ±8 sqrt(2)
The possible values of x are ±8 sqrt(2)
Solve this system using substitution: y=5x and 7x-3y=32
Solve equation [2] for the variable y
[2] 2y = -5x + 1
[2] y = -5x/2 + 1/2
// Plug this in for variable y in equation [1]
[1] 7x - 3•(-5x/2+1/2) = -5
[1] 29x/2 = -7/2
[1] 29x = -7
// Solve equation [1] for the variable x
[1] 29x = - 7
[1] x = - 7/29
// By now we know this much :
x = -7/29
y = -5x/2+1/2
// Use the x value to solve for y
y = -(5/2)(-7/29)+1/2 = 32/29
Solution :
{x,y} = {-7/29,32/29}

Find the length of the unknown leg of the right triangle.
Answer:
Step-by-step explanation:
a² + b² = c²
side1² + side2² = hypotenuse² side 1 = 6.75 hypotenuse = 11.25
solve for side 2 = ???
side2² = hypotenuse² - side1²
side2 = [tex]\sqrt{hypotenuse^2 - side1^2}[/tex]
= √(11.25² - 6.75²)
= √(126.56 - 45.56)
= √(81)
side 2 = 9

6: What is the volume of a cylinder
with a diameter of 10 feet and a
height of 8 feet? Use 3.14 for 1.
cubic feet
Answer: 628 cubic feet
Step-by-step explanation: First, find the area of the circle. Using the formula "TTr^2", you can find the area of the circle. Since the diameter is given, and not the radius, divide 10 by 2, and it gives you 5. Now, use the formula. 5 x 5 = 25, and then multiply it by 3.14 which gives you 78.5. Now that we have found the area of the circle, multiply the area by 8 to find the volume of the cylinder. 78.5 x 8 is 628 cubic feet, and that is the volume of the cylinder.

Step-by-step explanation:
Area of the rectangle
A=8(10)
A=80
Area of the circle
if d=8 then r=4
A= (1/2) 3.14(4)
A= (1/2) 3.14(16)
A=3.14(8)
A=25.12
Area of the whole thing
A=80+25.12
A=105.12ft sq
Write a SIMPLIFIED inequality for x that would give a rectangle with a length of 4 meters and a width of x+7 meters an area of more than 128 meters squared.
Answer:
128 > 4*(x + 7)
Step-by-step explanation:
Given the following data;
Length = 4 meters
Width = x + 7 meters
Area = 128 m²
Mathematically, the area of a rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
128 > 4*(x + 7)
128 > 4x + 28
128 - 28 > 4x
100 > 4x
Dividing both sides by 4, we have;
25 > x

6x - 6 = 6x -6
Answer:
All real numbers
Step-by-step explanation:
-distrubute 3 through parentheses
4x-6+2x=6x-6
-cancel equal terms on both sides
4x+2x=6x
-collect like terms
6x=6x
the statement is true for any value of x because both sides are true

Find the distance between S(2.3,4.8) and T(6.4,7.9).
Answer:
5.1
Step-by-step explanation:
thats what i got on savvas hope this helps!
The distance between the points S(2.3,4.8) and T(6.4,7.9) is 5.14 units.
What is distance between the points?Distance between two points is the length of the line segment that connects the two points in a plane.
Given that, two points S(2.3,4.8) and T(6.4,7.9), we need to find the distance between them,
The distance between the two points =
D = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Here, (x₁, y₁) and (x₂, y₂) are S(2.3,4.8) and T(6.4,7.9)
So,
D = [tex]\sqrt{(6.4-2.3)^2+(7.9-4.8)^2}[/tex]
= [tex]\sqrt{(4.1)^2+(3.1)^2}[/tex]
= [tex]\sqrt{26.42[/tex]
= 5.14
Hence, the distance between the points S(2.3,4.8) and T(6.4,7.9) is 5.14 units.

Lindsey purchased a random sample of 25 tomatoes at the farmers market. The 95% confidence interval
for the mean weight of the tomatoes is 90.6 to 112.4 grams.
What is the Point Estimate?
What is the Margin of error?
Answer:
3 & 5
Step-by-step explanation:
The value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.
What is the margin of error(MOE)?It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]
Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
Let's suppose m is a point estimate and ME is the margin of error.
The structure of the confidence interval is:
(m—ME, m + ME)
The given confidence interval is (90.6, 112.4)
Then, m—ME = 90.6 ..... (1)
m + ME = 112.4 ..... (2)
After solving equation (1) and (2) we get:
m = 101.5
ME = 10.9 grams
Thus, the value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.
