C=1/2e•n solve for e
Answer:
e = 2(C/n)
Step-by-step explanation:
C = 1/2e*n
solving for e
1/2e*n = C
(1/2e*n)/n = C/n
1/2e = C/n
(1/2e) × 2 = (C/n) × 2
e = 2 (C/n)
Given the figure below, calculate its area.
Answer:
1+√3
Step-by-step explanation:
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * AC * BD
We need to get AC
AC = AD+DC
Get base AD using SOH CAH TOA
tan 45 = 4/AD
AD = 4/tan45
AD = 4/1
AD = 4
Get DC
tan 30 = 4/DC
DC = 4/tan 30
DC = 4/(1/√3)
DC = 4√3
AC = 4 + 4√3
AC = 4(1+√3)
Get the Area of the triangle
Area = 1/2 * 4 * 4(1+√3)
Area of the triangle = 1+√3

Pork sausages
Packs of 10,3 for £10.00
Pack of 6 for £2.00
Packs of 10, 4 for £12.00
I think its packs of 6 for £2.00
Answer:
b
Step-by-step explanation:
a pack of 6 = £2.00
then two packs of 6= £4.00
that means it is cheaper than the rest of which you obtain more sausages at a cheaper rate
The faucet in my kitchen has a leak and is constantly dripping. At 7:00 a.m., I placed a
measuring cup under the drip. When I got home at 3:00 p.m. the cup was full. If this drip rate
continues, how many gallons of water are wasted in a 7-day period of time?
Answer:
1.3125 gallons would have been wasted in 7 days
Step-by-step explanation:
mathematically, there are 0.0625 gallons in a measuring cup
So within the time frame, 0.0625 of liquid was lost
The time frame is 8 hours difference
The number of hours in 7 days will be;
7 * 24 = 168 hours
0.0625 gal in 8 hours
x gal in 168 hours
x * 8 = 168 * 0.0625
8x = 10.5
x = 10.5/8
x = 1.3125 gallons
Mr. G rents a truck for 3 hrs at $80 and then rents it again for an additional 5 hrs at $320. What was his rate of change for Mr. G during his second period of rental?
A. $120/hr
B. $240/hr
C. $1/120hr
D. $2/240hr
Answer:
Rate of change for Mr. G during his second period of rental is :---
[tex] →\frac{(\$320 - \$80)}{(5hr - 3hr)} = \frac{\$240}{2hr} = \boxed{\$120{hr}^{-1}} \\ [/tex]

Olivia makes and sells muffins and scones at
a school bake sale. She sells muffins for $0.50
each and scones for $0.80 each. She hopes
to raise at least $20. The inequality 0.50x
+ 0.80y z 20 represents the possible ways
Olivia could reach her goal. Is the ordered pair
(20,32) a solution for the problem situation?
9514 1404 393
Answer:
yes
Step-by-step explanation:
We can substitute the proposed solution values and see if the inequality is true.
0.50x +0.80y ≥ 20
0.50(20) + 0.80(32) ≥ 20
10 + 25.6 ≥ 20
35.6 ≥ 20 . . . . . . true; (20, 32) is a solution

Jim went to the playground. He played on the swings for 45 minutes and went on the slide for 55 minutes. It was 4:35 P.M. when Jim left the playground. What time was it when Jim arrived at the playground?
Answer:
2:55 P.M.
Step-by-step explanation:
First, add the amount of time Jim played outside; 45+55=100
100 minutes is equal to 1 hour 40 minutes.
If he left the playground at 4:35 P.M., then you have to subtract in order to find out when he arrived there.
Subtract 1 hour 40 minutes from 4:35 P.M. to then get 2:55 P.M.
To confirm your answer, you can add back the 1 hour and 40 minutes to 2:55 P.M. and you'll get 4:35 P.M.; back with what you started with.
Hope this helped !!!

Solve y - 3x = 13 for y
y = ?
Answer:
y = 3x + 13
Step-by-step explanation:
Here, we want to solve for y
To solve for y, we simply are going to make y the subject of the formula
We have this as;
y - 3x = 13
y = 13 + 3x

The ratio of side lengths of a quadrilateral is 3 : 5 : 6 : 9, and its perimeter is 9.2cm. What is the length of the longest side?
Answer:
longest side=3.6
let ratio 3:5:6:9be 3x,5x,6xand9x
perimeter= sum of all side
9.2=3x+5x+6x+9x
9.2=23x
x=9.2÷23
x=0.4
9x=9×0.4=3.6
6x=6×0.4=2.4
5x=5×0.4=2
3x=3×0.4=1.2
Find the 10th term of the geometric sequence 5, 25, 125, ....
Answer:
The answer would be 9,765,625
Step-by-step explanation:
5 to the power of 10 is 9,765,625
Answer:
Step-by-step explanation:
Geometric sequence 5, 25, 125, ....
First term = a = 5
Common ratio = r = 2nd term ÷ first term
= 25 ÷ 5
= 5
n = 10
nth term = ar⁽ⁿ ⁻ ¹⁾
10th term = 5 * 5⁹
= 5 * 1953125
= 9765625

What is the equation of the vertical asymptote for the graph below ?
y = 5 + 1 / x + 3
The equation of the vertical asymptote is x = -3
The function is given as:
[tex]y =\frac{5x +1}{x + 3}[/tex]
Assume the equation of the function is:
[tex]y =\frac{m(x)}{n(x)}[/tex]
So, by comparison;
We have:
[tex]n(x)=x + 3[/tex]
Set n(x) to 0
[tex]x + 3 = 0[/tex]
Subtract 3 from both sides
[tex]x = -3[/tex]
Hence, the equation of the vertical asymptote is x = -3

In the World Cup Downhill held at Panorama Mountain Village in British Columbia, the skiers raced 3514 m down the mountain. If the vertical height of the course was 984 m, determine the average angle of the ski course with the ground.
Answer:
16.3°
Step-by-step explanation:
This question above is a Trigonometry question that is solved using the formula of Sine
sin θ = Opposite/Hypotenuse
Opposite = The vertical height of the course = 984 m
Hypotenuse = The distance the skiers raced down the mountain = 3514 m
θ = The average angle of the ski course with the ground = ?
sin θ = 984 m/3514 m
sin θ = 0.2800227661
θ = arc sin (0.2800227661)
= 16.261563463°
≈ 16.3°
Therefore, the average angle of the ski course with the ground is 16.3°
