A 150 W driveway light produces 9.3 × 104
J of light energy
over a 4.0 h period. If the light uses 2.06 × 106
J of energy in
the 4.0 h, then what is its efficiency?
Show all work
Answer:
4.51456%
Step-by-step explanation:
Efficiency equation: output/input*100%
(9.3*10^4)/(2.03*10^6)*100 = 4.51456%

Answer:
when you first go on to brainly it should say scan if you are on a chrome book it doesn't work
Step-by-step explanation:
Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
y=-3x + 3
y=-3x - 6
y = 3x - 3
y = 3x - 1
Answer:
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.
Step-by-step explanation:
We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
The equation will be of slope-intercept form: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept
We are given slope m =-3, we need to find y-intercept b
Finding y-intercept
using slope m=-3 and point (-1, 6)
[tex]y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3[/tex]
So, y-intercept b is 3
Now the equation of line having slope m= -3 and y-intercept b = 3 is
[tex]y=mx+b\\y=-3x+3[/tex]
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.
Answer:

James makes $15 per hour. He works 40
hours per week. He gets paid every week. If
he has to pay 10% for FICA, 7.5% for Social
Security, and 2.9% for Medicare, what is his
take home pay or his Net Income?
Answer:
i got 485!
Step-by-step explanation:
multiply 40 by $15 = 600 then subtract 10% = 540 then subtract 7.5% = 499.5 lastly subtract 2.9% = 485 and that's his take home money :)

1. If the diameter of a circular object is 10 feet. Find the radius and the circumference. Use 3.14 for π.
2. Find the perimeter of the window. R = 4ft
Answer:
1.
[tex]Radius = 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
2.
[tex]Perimeter = 25.12\ ft[/tex]
Step-by-step explanation:
Solving (1):
Given
[tex]Diameter = 10ft[/tex]
Required
Determine the radius and circumference
Radius is calculated as follows:
[tex]Radius = \frac{1}{2} * Diameter[/tex]
[tex]Radius = \frac{1}{2} * 10ft[/tex]
[tex]Radius = 5ft[/tex]
The circumference is calculated using:
[tex]Circumference = 2 * \pi * Radius[/tex]
[tex]Circumference = 2 * 3.14 * 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
Solving (2):
Given
[tex]R = 4ft[/tex]
Assume that the window is circular, the perimeter is calculated as follows:
[tex]Perimeter = 2 * \pi * R[/tex]
[tex]Perimeter = 2 * 3.14 * 4ft[/tex]
[tex]Perimeter = 25.12\ ft[/tex]
At the beginning of last year,there were 368 students at the elementary school.By the beginning of this year,72 of those students have moved to other school districts and 64 new students arrived. about how many students started the school year this year
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.

What is the explicit rule for this geometric sequence?
2/9,2/3,2,6,...
an=3(29)n−1
an=3(29)n
an=29⋅3n−1
an=29⋅3n
Answer:
Tn = 2/3^(n-1)
Step-by-step explanation:
The nth term of a geometric progression is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is t common ratio
From the sequence
a = 2/9
r = (2/3)/(2/9) = 2/(2/3) =3
Substitute
Tn = 2/9(3)^(n-1)
Tn = 2/3^(n-1)
Hence the required equation is Tn = 2/3^(n-1)
Answer:
the actual answer is [tex]a_{n}[/tex][tex]=(\frac{2}{9} )3^{n-1}[/tex]

find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if necessary.
Answer:
y=1 3/5x+-5
Step-by-step explanation:
So the y intercept is where your slope meets the middle, basically the y. So it hit the y on -5. And the rise and run 8/5 rise is 8 and run is 5. 8/5= 1 3/5. in equation it is y=1 3/5x+-5.

A mixture of nuts contains 2 kg of cashew nuts and
600 grams of peanuts. What is the ratio of peanuts to cashew nuts in the mixture?
Answer:
3 : 10
Step-by-step explanation:
2 kg = 2000g
600g peanuts : 2000 cashew nuts
600 : 2000
divide both sides by a common divisor ( 200)
600/200 : 2000/200
3 : 10

An artist made a cone out of stainless steel, then sliced it into 3 pieces to use to make a sculpture. The original cone and the 3 pieces are shown below. ( I have attached the picture)
What is the volume of the largest piece?
A. 2,375 π cubic centimeters
B. 2,500 π cubic centimeters
C. 3,250 π cubic centimeters
D. 3,375 π cubic centimeters
Answer:
3375 [tex]\pi \\[/tex] cubic centimeters
Step-by-step explanation:
Trick question: The largest piece is the entire cone.
First lets identify the equation for volume.
V= 1/3 h pi r^2
h=45
r=15
V= 1/3 45 * pi 15^2
v= 15* pi 225
3375 pi
You keep pi because the answer has pi.

If x is greater than 0, what is the difference of 6x√14x - 5√56x^3 in simplest radical form?
Answer:
6x√14x - 5√56x^3 = -4√14x√x
I hope this helps at least. :)
Simply put, expressing a radical in its lowest extreme form implies simplifying it and that there are no more squared roots, cube roots, 4th roots, and so on to find. This also entails eliminating any radical from a fraction's base, and further calculation can be defined as follows:
Given:
[tex]\to \bold{6x\sqrt{14x} - 5\sqrt{56x^3}}[/tex]
To find:
simplest radical form=?
Solution:
[tex]\to \bold{6x\sqrt{14x} - 5\sqrt{56x^3}}[/tex]
[tex]\to \bold{6x\sqrt{14x} - 5 \sqrt{4 \times 14 \times x \times x \times x}}\\\\\to \bold{6x\sqrt{14x} - 5 \times 2x \sqrt{ 14 x}}\\\\\to \bold{6x\sqrt{14x} -10x \sqrt{ 14 x}}\\\\\to \bold{\sqrt{14x} (6x-10x)}\\\\\to \bold{\sqrt{14x} (-4x)}\\\\\to \bold{-4x\sqrt{14x} }\\\\[/tex]

The cordinate of point A on a grid are (-3,-2). Point A is reflected across the y-axis to obtain part B. The coordinates of point B are (__,-2)
Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate gets multiplied by -1 and the y-coordinate remains the same.
A(-3, -2) => B(3, -2).

Answer:
Option D
Step-by-step explanation:
(10x + 13) + (12 + 9x) + ( 13x + 12) + 55 + 44 = 360
32x + 136 = 360
Subtract 136 from both sides;
32x = 224
Divide both sides by 32;
