[tex]\sqrt{2} +1[/tex] is not in a denominator to rationalize
if it were you would multiply the rational expression (the fraction)
by [tex]\frac{\sqrt{2} -1}{\sqrt{2} -1}[/tex] the result (in the denominator would end up being "2 -1"
which is 1

A shipping container is in the shape of a right rectangular prism with a length of 9 feet, a width of 12 feet, and a height of 14.5 feet. The container is completely filled with contents that weigh, on average, 0.83 pounds per cubic foot. What is the weight of the contents in the container, to the nearest pound
Answer:
1,300 lb.
Step-by-step explanation:
V = 9 × 12 × 14.5 = 1566 ft³
1,566 × 0.83 = 1,299.78 ≈ 1,300 lb.
What would the equation, slope, and y-intercept be for this?
Answer:
y=-4x+1
Step-by-step explanation:
Equation: y=mx+b where m = slope and b= y intercept
TO find the slope, find the change in y over the change in x , or just to rise over run
From (-1,5) to (0,1), the y changes by -4 and the x changes by 1.
So the slope will be -4
To find the y intercept, find the point at which the line crosses the y-axis.
In this case, it is at (0, 1), so your y intercept will be 1
Plug all this info back into the equation and you get y=-4x+1
The y-intercept is 1 and that’s it sorry I can’t answer the rest.
f(x) = Square root of quantity x plus seven. ; g(x) = 8x - 11 Find f(g(x)). (1 point)
f(g(x)) = 2 Square root of quantity two x plus one
f(g(x)) = 8 Square root of quantity x plus seven - 11
f(g(x)) = 8 Square root of quantity x plus four
f(g(x)) = 2 Square root of quantity two x minus one
Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt(x+7)
g(x) = 8x-11
f(g(x))=
Place g(x) in for x in the function f(x)
f(g(x)) = sqrt( 8x-11 +7)
= sqrt( 8x -4)
Factor out 4
= sqrt( 4(2x-1)
= 2 sqrt(2x-1)
[tex]\\ \sf\longmapsto f(x)=\sqrt{x+7}[/tex]
[tex]\\ \sf\longmapsto g(x)=8x-11[/tex]
g(x) will be put on the place of x[tex]\\ \sf\longmapsto f(g(x))=\sqrt{8x-11+7}[/tex]

-144π = -12πk
Answer:
k = 12
Step-by-step explanation:
isolate the variable; divide both sides that dont contain the variable
Answer:
K=12
Step-by-step explanation:
-144π = -12πk
divide by -12π on both sides to find k
-144π / -12π = k
12 = k

Hi can someone help me with these 3 questions. Thanks :)
Answer:
a) 45° cause tan = sin/cos and sin 45 and cos 45 both give square root 2/2
b) 120°
c) sin = -1/2 = -30° or 330° both are same
Use the trig circle which i have included in the answer to better understand trig angles
hope that answers your question
I want to let you know that each angle has sets of coordinates the left number is cos and right is sin. Ex) sin of 30 is 1/2 and cos of 30 is square root 3/2 In case you dont fully understand dont hesitate to comment.

Two solid spheres have surface areas of 1441 cm? and 2567 cm² respectively. They are melted and recast to form a larger sphere. Find the surface area of the larger sphere in square centimetres.
Surface area of small sphere = 1441cm^2
Surface area of bigger sphere = 2567cm^2
Surface area of largest sphere = 1441 + 2567
= 4008cm²

Help me you guys! it's important!
Answer:
hey mate
surface area of cuboid is 2(lh+bh+hl)
doing for first cuboid
h = 20
l = 6
b = 5
surface area for this cuboid on calculating u get 500 sq.cm
now
second cuboid
h = 12
l = 6
b = 4
calculaye it by formula and u get 288 sq.cm
so total surface area is 500 + 288 = 788 but in this one side is getting counted 2 times which is rectangle with length 6 and 12 so it's area is 12×6 = 72
final ans = 788-72 = 716 cm2
as per me that's ans

how many solutions in 3(6x-2) = 2(9x-3)
Answer:
Infinite solutions
Step-by-step explanation:
Distribute the numbers
3(6x-2) = 18x - 6
2(9x-3) = 18x - 6
18x - 6 = 18 - 6
Since both sides of the equal sign are the same, that means you can plug any number into x, and it will always be a valid answer.
the sum of two resistors in 750 ohms. One is 6.5 times the other. Find the size of each resistor in ohms.
Answer:
r = 100
6.5r = 650
Step-by-step explanation:
let r be resistors.
6.5r + r = 750
Simplify:
6.5r + r = 750
7.5r = 750
------ ------
7.5 7.5
r = 100
100 × 6.5 = 650
One resistor is 100 ohms, and he other is 650 ohms.
Hope this helped.
The sum of two resistors in 750 ohms. One is 6.5 times the other. Find the size of each resistor in ohms.
S O L U T I O N :According to the question, here we need to take a variable to find the size of each resistor then multiply 6.5 with the variable with the first one. For the second there is no change in the variable. Then adding them we get 750 ohms. Simplifying we get their respective size
Let us assume the other resistor's size be x
Here,
The First resistor's size is 6.5 times the other. Hence, the no. is 6.5x
Given that : the sum of two resistors in 750 ohms
1st Resistor + 2nd Resistor = 750 ohms 6.5x + x = 750 ohms7.5x = 750 ohms x = 750/7.5 ohms x = 100 ohmsFINDING SIZE :
First Resistor's Size = 6.5x = 6.5*100 = 650 ohms
Other Resistor's Size = x = 100 ohms

Martha and Bob went running. They started down the path at 3:25 P.M. When they finished running it was 4:30 P.M. How long did the run take?
Answer:
1 hour and 5 minutes, or 65 minutes.
Step-by-step explanation:
Let's suppose 3:25 was 3:30 by rounding up 5 minutes, to make life easier. In one hour, it would be 4:30, which is when Martha and Bob finished running. So we know that between 3:25 and 4:30, they at least ran one hour. Now, since we rounded up 5 minutes, we have to add that too to make our final running time for them, 1 hour and 5 minutes. Hope this helped!

-72 + (-30) + 10 =
-72-30+10.
-72-30=-102
10-102 is also the same as
-102+10
The final answer is -92
Answer:
-92
Step-by-step explanation:
-72 + (-30) + 10 =
-72+ -30
Since they both have the same sign, add and then take the sign
72+30 = 102 and then take the negative sign
-102
-102+10
They have opposite signs, so we subtract and take the sign of the larger
102 -10 = 92
And 102 was negative so take the negative sign
-92
