question:
a fish tank has a volume of 1176 cubic inches. the length and height are 14 and 8 inches each respectively. using this information, find the missing width.
(please put the work since i need to put it in)
please and thank you!
Answer:
volume is the product of the 3 dimensions. so devide the volume by the height and by the length to get just the width
1176 / 14 / 8
= 10.5

- I = 12
The solution is r =
Answer:
Step-by-step explanation:
[tex]7- \sqrt[3]{2-x} =12[/tex]
we have to just keep in mind to do the same operation to both sides of the equal sign
[tex]7-7- \sqrt[3]{2-x} =12-7[/tex] ; subtract 7 from both sides
[tex]- \sqrt[3]{2-x} = 5[/tex] ; multiply both sides by -1
[tex]\sqrt[3]{2-x} = -5[/tex] ; raise both sides to the power 3
2-x = (-5)³
2-x = -125 ; subtract 2 from both sides
-x = -125-2
-x =-127; multiply both sides by -1
x= 127

When adding two numbers, the number of significant figures in the sum is equal to the number of significant figures in the least accurate of the numbers being added. Group of answer choices True False
Answer: The given statement is true.
Step-by-step explanation:
Significant figures are defined as the figures that are present in a number. It expresses the magnitude of a quantity to a specific degree of accuracy.
There are some rules to detect the significant figures in a number:
All digits ranging from 1 to 9 are always considered significant.Every non-zero number is always considered significant. For example, 274, 2.74, and 27.4 all have three significant figures.All zero’s that are present between the integers is always considered significant. For example, 5007, 5.007, and 50.07 all have four significant figures.All zero’s preceding the first integer is never considered significant. For example, 0.0089 has two significant figures.All zeros that are present after the decimal point are always significant. For example, 4.800, 48.00, and 480.0 all have four significant figures.Rule applied when numbers are added or subtracted:
The number having less number of significant figures after the decimal point will determine the number of significant figures in the final answer.
Hence, the given statement is true.

Find area of shape?
Answer:
521.1 mm²
Step-by-step explanation:
The shape is made up of a semicircle and a trapezoid.
Area of the shape = area of the semicircle + area of the trapezoid
= ½(πr²) + ½(a + b)*h
Where,
r = radius of the semicircle = ½(20) = 10 mm
a = 20 mm
b = 32 mm
h = height of trapezoid = 14 mm
Plug in the values
Area of the shape = ½(π*10²) + ½(20 + 32)*14
= 157.1 + 364
= 521.1 mm²

a = -351.68 ft² area of the walkway minus the area of the fountain
Step-by-step explanation:
Area fountain
a = π16²
a = 256π
Area fountain and walkway
a = π(16 + 4)²
a = π20²
a = 400π
Area Walkway
a =400π - 256π
a = 144π
a = 144 * 3.14
a = 452.16 ft²
------------------------------
I think the Area of the Walkway is what the question should be asking for, but it asked for
"the area of the walkway minus the area of the fountain"
a = 144π - 256π
a = -112π
a = -112 * 3.14

On a coordinate plane, line A B goes through (negative 2, 4) and (2, negative 8). Point C is at (6, 4).
Which point on the y-axis lies on the line that passes through point C and is perpendicular to line AB?
(–6, 0)
(0, –6)
(0, 2)
Answer:
A. (-6,0)
Step-by-step explanation:
The point on the y-axis lies on the line that passes through point C and is perpendicular to line AB is (-6, 0). Therefore, option C is the correct answer.
Given that, on a coordinate plane, line AB goes through (-2, 4) and (2, -8). Point C is at (6, 4).
What is the slope of a line?The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line.
The slope is represented by the letter m, and is given by, m = tan θ = (y2 - y1)/(x2 - x1)
Now, slope of line AB with (x1, y1) = (-2, 4) and (x2, y2) = (2, -8) is
Slope = m = (-8-4)/(2(-2)
= -12/4
= -3
Slope perpendicular to AB = -1/m = -1/(-3)
=1/3
Put m=1/3 and C(6, 4) in y=mx+c, we get
4 = 1/3 (6) + c
⇒ c = 4-2
⇒ c = 2
Substitute m=1/3 and c = 2 in y = mx+c
That is, y = x/3 + 2
⇒ 3y = x+6
Point on the y-axis lies is 3(0) = x+6
⇒ x=-6
So, the coordinate is (-6, 0)
The point on the y-axis lies on the line that passes through point C and is perpendicular to line AB is (-6, 0). Therefore, option C is the correct answer.

find r if 0=pi/6 rad sector 64m^2
Given:
Area of a sector = 64 m²
The central angle is [tex]\theta=\dfrac{\pi}{6}[/tex].
To find:
The radius or the value of r.
Solution:
Area of a sector is:
[tex]A=\dfrac{1}{2}r^2\theta[/tex]
Where, r is the radius of the circle and [tex]\theta [/tex] is the central angle of the sector in radian.
Putting [tex]A=64,\theta=\dfrac{\pi}{6}[/tex], we get
[tex]64=\dfrac{1}{2}r^2\times \dfrac{\pi}{6}[/tex]
[tex]64=\dfrac{\pi}{12}r^2[/tex]
[tex]64\times \dfrac{12}{\pi}=r^2[/tex]
[tex]\dfrac{768}{\pi}=r^2[/tex]
Taking square root on both sides, we get

Answer:
y = (1/2) x + 3
Step-by-step explanation:
The equation of linear functions is y = m x + b
In this case, we know m = 1/2 , and have point (4,5). We only need to find our y-intercept or b value.
What we can do is substitute what we know into our formula which will give us variable b, or the y-intercept. That will look like:
5 = (1/2) * 4 + b
5 = 2 + b
3 = b
So, the equation is y = (1/2) x + 3 :)

x² = 17(272) = 4624
x = ±√4624 = ±68

I would greatly appreciate it if someone could help me with this. A car travelled 400 km in 5 hours. Joe calculated the speed as 80 km/h but, when he graphed the relation, he calculated a slope of 0.0125. What do you think Joe did incorrectly?
It sounds like Joe calculated 5/400 = 0.0125
He divided in the wrong order. It should be 400/5 = 80 since we divide distance over time to get the speed (or rate).
-----------------
In terms of x and y, we basically are saying
slope = rise/run
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (400 km)/(5 hrs)
slope = 80 km per hour is the speed
