Given that £ 42 is distributed among 3 friends.
So, each will get
[tex] = 42 \div 3 \\ = £14[/tex]Ricardo is creating a budget for himself to set goals on how much money he wants to save. At his current job, he makes $300 per week, and spends $40 each week on his expenses. If he wants to save a total of at least $2,600, how many weeks at minimum does he have to work for in order to reach his goal?
Answer:
10 Weeks
Step-by-step explanation:
If he makes $300 every week minus $40 for his expenses and needs $1200. 300-40=260..... 260x10=1200 So he would have to work 10 weeks at a minimum.
The number of weeks at minimum does he have to work for in order to reach his goal is 10 weeks.
What is unitary method?The unitary method is used to find the value of a single unit from a given multiple.
For example, the price of 40 pens is Rs. 400
It should be noted that the concept of ratio and proportion is used for problems related to this method.
According to questions,
He makes $300 per week
and spends $40 each week on his expenses.
Therefore his total savings per week = $300 - $40
= $260.
Also he wants to save a total of at least $2,600.
Thus number of weeks at minimum does he have to work for in order to reach his goal = $2600 ÷ $260
= 10 weeks.
Hence the required number of weeks = 10 weeks.

Among 420 randomly selected employees at a company, the mean number of hours of overtime worked per month is 10 hours and the standard deviation is 1. 6. What is the margin of error, assuming a 99% confidence level? 4. 12 0. 01 0. 20 20. 5.
The margin of error of the random selection is 0.20
The given parameters are:
[tex]n = 420[/tex] --- the sample size
[tex]\sigma = 1.6[/tex] --- the standard deviation
[tex]\bar x = 10[/tex] --- the mean
[tex]\alpha = 99\%[/tex] --- the confidence level.
The margin of error (E) is calculated as follows:
[tex]E = z \times \sqrt{\frac{\sigma^2}{n}}[/tex]
So, we have:
[tex]E = z \times \sqrt{\frac{1.6^2}{420}}[/tex]
[tex]E = z \times \sqrt{\frac{2.56}{420}}[/tex]
The z-value for 99% confidence level is 2.576.
Substitute 2.576 for z
[tex]E = 2.576 \times \sqrt{\frac{2.56}{420}}[/tex]
[tex]E = 2.576 \times \sqrt{0.006095}[/tex]
Take square roots
[tex]E = 2.576 \times 0.0781[/tex]
Multiply
[tex]E = 0.2012[/tex]
Approximate
[tex]E = 0.20[/tex]
Hence, the margin of error is 0.20

Answer:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So \frac{\lambda }{2}=20cm
2
λ
=20cm
\lambda =40cmλ=40cm
We have to find the speed of the wave in the string
Speed is equal to v=\lambda f=0.04\times 80=3.2m/secv=λf=0.04×80=3.2m/sec
So speed of the wave in the string will be 3.2 m/sec

Answer:
(6x-8)+(3x)+x=180 - the equation that would be used to find x
Step-by-step explanation:
(6x-8)+(3x)+x=180
I´m not sure what the answer of the equation is but this is the equation. im sorry :(
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
3x + x + 6x - 8 = 180 , that is
10x - 8 = 180 ( add 8 to both sides )
10x = 188 ( divide both sides by 10 )
x = 18.8
3x = 3 × 18.8 = 56.4
6x - 8 = 6(18.8) - 8 = 112.8 - 8 = 104.8
Then the 3 angle measures are
18.8° , 56.4° , 104.8°

55.7 degrees is the same as 55 degrees _____' 12"
Answer:
16
Step-by-step explanation:
Given is a degree in decimals as 55.27 degrees
But normally in degrees, we use for part of degrees minutes and seconds
60 seconds make one minute and 60 minutes make one degree.
Here 55 degrees would be the same
But part degree 0.27 = 27/100
If we want to convert this into minutes multiply by 60
No of minutes =
1/5 minutes = 12 seconds
Hence 55.27 = 55 deg 16 min and 12 seconds

Step-by-step explanation:
So Josh is 6 years older than kims age and the sum of the ages is less than 31, the greatest number that is less than 31 is 30 so we can use that.
We can make an equation out of this and solve it.
n+(n+6)=30
2n+6=30
2n=24
n=12
12 is the oldest Kim could be.
12+(12+6)=12+18=30.
