Power usage is measured in kilowatt-hours, kWh. After 7 a.m., the power usage on a college campus increases at a rate of 21% per hour. Prior to 7 a.m., 15,040 kWh have been used. The university has a daily goal to keep their power usage less than or equal to 100,000 kWh.
Which of the following inequalities can be used to determine the number of hours, t, after 7 a.m. when the power usage on campus will be less than or equal to 100,000?A.
15,040(0.79)t ≤ 100,000
B.
15,040(1.79)t ≤ 100,000
C.
15,040(1.021)t ≤ 100,000
D.
15,040(1.21)t ≤ 100,000
Answer:
D. 15,040(1.21)t ≤ 100,000
Step-by-step explanation:
The 15,040 is the prior electricity, and it increases by .21 per hour, and you don't want 100,000
To make an equation, use the simple interest formula (same concept)
Total = Amount(1 + rate) time
fill it out
100,000 >= 15,040(1.21)t
This equation is the same as D so D is the answer
How many flowers, spaced every 4 in., are needed to surround a circular garden with a 200-ft radius? Use 3.14 for π.
Find the circumference of the circle:
Circumference = 2 x r x pi
Circumference = 2 x 200 x 3.14
Circumference = 1,256 feet.
4 inches/ 12 inches per foot = 0.333 ft.
Divide the circumference by the spacing:
1255/0.333 = 3,768
You will need 3,768 flowers

N is between A and X. AN = 2x + 1, NX = 3x, and AX = 21. what is AN?
Answer:
AN = 9
Step-by-step explanation:
so we can imagine this in a line like:
A---------------N---------------X
Step 1 : solve for x
AX=21 (our total)
because we know that AN+NX together makes AX, we put that into an equation
AN + NX = AX
(2x+1) + (3x) = 21
2x + 1 + 3x = 21 <-- subtract 1 from both sides
2x + 3x = 20 <-- add 2x +3x
5x = 20 <-- divide 5 from both sides
x = 4
Step 2 : input x into AN
AN = 2x + 1 <-- input 4 for x
AN = 2(4) + 1 <-- simplify from there
AN = 9

Answer:
m = 8
Step-by-step explanation:
As we can see we have two similar triangles
These are triangles FDH and GEF
mathematically, when two triangles are similar, the ratio of their corresponding sides are equal;
Thus;
DH/DF = EG/EF
12/15 = m/10
15 * m = 12 * 10
15 m = 120
m = 120/15
m = 8

A z=0.8
B z=0.9
C z=2.8

Step-by-step explanation:
1/3(6z + 7.2) = 0.5(8z + 2) - 0.4
Multiply both sides by 6.
12z + 14.4 = 24z + 6 - 2.4

O Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue.
O Winning a raffle that sold a total of 100 tickets if you bought 9o tickets.
OReaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.
Answer:
The first one
Step-by-step explanation:
This is because all the other ones there is a likely chance that you will get them. While the first one it is less of a chance that you will role a die and land on a one. It is a 1 out of 6 chance
The situation which is unlikely is rolling a 1 on a standard six-sided die, numbered from 1 to 6
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
a)
Rolling a 1 on a standard six-sided die, numbered from 1 to 6
Probability P ( A ) = 1/6
P ( A ) = 0.1667
b)
Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue
Probability P ( A ) = 1
P ( A ) = 1
c)
Winning a raffle that sold a total of 100 tickets if you bought 90 tickets.
Probability P ( A ) = 90/100
P ( A ) = 0.9
d)
Reaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.
Probability P ( A ) = 10/20
P ( A ) = 0.5
Hence , the unlikely event is Rolling a 1 on a standard six-sided die, numbered from 1 to 6

A sound wave is traveling at 6,420m/s and has a frequency of 600Hz. What is the wavelength?
Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m[/tex]
So, the wavelength of the sound wave is equal to 10.7 m.
Los términos 32 , 16 , 8 , 4 ................, representan una PG .Calcular a) R b) El término décimo c) La suma de los 10 primeros términos
Respuesta:
T₁₀ = 1/16
S₁₀ = 63,9375
Explicación paso a paso:
Dado el término de un médico de cabecera como 32, 16, 8, 4 ...
El enésimo término de un médico de cabecera se expresa como;
Tn = arⁿ⁻¹
a es el primer término
r es la razón común
n es el número de términos
Dado
a = 32
r = 16/32 = 8/16 = 4/8 = 1/2
n = 10 (ya que necesitamos el décimo término de la secuencia)
Sustituir en la fórmula;
Tn = arⁿ⁻¹
T₁₀ = 32 (1/2) ¹⁰⁻¹
T₁₀ = 32 (1/2) ⁹
T₁₀ = 32 (1/512)
T₁₀ = 32/512
T₁₀ = 1/16
Por lo tanto, el décimo término de la secuencia es 1/16.
La suma de un GP se expresa como se muestra;
Sₙ = a (1-rⁿ) / 1-r para r <1
S₁₀ = 32 (1- (1/2) ¹⁰) / 1-1 / 2
S₁₀ = 32 (1-1 / 1024) / 1/2
S₁₀ = 64 (1 - 1/1024)
S₁₀ = 64 (1023/1024)
S₁₀ = 63,9375
por lo tanto, la suma de los primeros diez términos es 63,9375

Write an inequality and find the minimum number of hours, to the nearest hour, ... additional $100 in tips waiting tables on Saturday He earned at least $160 in all
The inequality for the given situation is 7.55x+100≥160. Therefore, the minimum number of hours x ≥ 8.
Given that, Shnaggy earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday he earned at least $160 in all.
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Let the number of hours be x.
Now, 7.55x+100≥160
Subtract 100 on both the sides of inequality, that is
7.55x+100-100≥160-100
⇒ 7.55x≥60
Divide 7.55 on both the sides of inequality, that is
7.55x/7.55 ≥ 60/7.55
⇒ x ≥ 7.94
7.94≈8
The inequality for the given situation is 7.55x+100≥160. Therefore, the minimum number of hours x ≥ 8.

how many apples would be left?
Hello!
Lets tackle each section separately!
So Robin gives the first group [tex]\frac{1}{8}[/tex] of the apples.
To find how many apples that is in standard form, we divide 40 by 8.
40 ÷ 8 = 5.
So the first group ate 5 apples.
The second group ate 4 apples.
We do not have to calculate anything since it is already in standard form.
The third group ate 20% of the apples.
To find 20% of forty we can multiply 40 by 0.20, since 0.20 is the decimal equivalent of 20%.
40 × 0.20 = 8.
The last group of children ate 8 apples.
Now we add each groups apple intake together.
5 + 4 + 8 = 17.
Finally, we subtract 17 from 40.
40 - 17 = 23.
There were 23 apples left.
