Answer:

A complete angle is one which measures 360∘360∘.

The three angles

6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘

add up to 360∘360∘, as per the question.

6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘

⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘

⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘

⟹2x+3y+z=90∘⟹2x+3y+z=90∘

This is the required relation.

Answer:

1/6 and 40

Step-by-step explanation:

for 1/6 you can get the answer by getting 1/2 chicken = 3/6 then 1/3 tomato soup = 2/6 and you have 1/6 left which will be the answer.

For the number of people, 1/6 is equal to 40 because 240 divided by 6 equals 40

Answer:

9

Step-by-step explanation:

Let the integer be n

According to the text

30 / (n + 1) = 24 / (n-1)

Cross multiply we have

30 (n -1) = 24 (n + 1)

30 n - 30 = 24 n +24

30n -24n = 30 + 24

6n = 54

n = 9.

So the integer is 9.

The greatest possible length of time will be "1020 min".

Given:

The average length of time,

= 960

For all 3 computers,

The minimum length of time,

= 930

Let,

Now,

→     [tex]\frac{930+930+930+x}{3} = 960[/tex]

→  [tex]\frac{930+930+930}{3} +\frac{x}{3} =960[/tex]

→           [tex]\frac{3\times 930}{3} +\frac{x}{3} =960[/tex]

→              [tex]930+\frac{x}{3}=960[/tex]

→                        [tex]\frac{x}{3} = 960-930[/tex]

→                        [tex]x = 30\times 3[/tex]

→                        [tex]x = 90[/tex]

hence,

The greatest possible length of time will be:

=  [tex]930+x[/tex]

=  [tex]930+90[/tex]

=  [tex]1020 \ min[/tex]

Thus the above is the appropriate answer.

Answer:

$35.50

Step-by-step explanation:

With a 20% profit then $42.60 represents 120%

We require to find the cost price represented by 100%

Divide the amount by 120 to find 1% then multiply by 100, that is

cost price = [tex]\frac{46.60}{120}[/tex] × 100 = $35.50

25% markup = original + 25% = 125% of original = 1.25 x original

Selling price = 1.25 x dealer price

Answer = 521.25/1.25=$417

The dealers price would be 100% they sell it for 10% more so it is sold at 110 % of what the dealer pays.

Divide the selling price by 110% to get the dealers cost.

638 / 110% = 638 / 1.1 = 580

The dealers cost is $580

Step-by-step explanation:

Answer:

QS = 76

Step-by-step explanation:

Given R is the midpoint of QS , then

RS = QR , that is

5x - 17 = 2x + 16 ( subtract 2x from both sides )

3x - 17 = 16 ( add 17 to both sides )

3x = 33 ( divide both sides by 3 )

x = 11

Then

QS = QR + RS

     = 2x + 16 + 5x - 17

     = 7x - 1

    = 7(11) - 1

    = 77 - 1

Hey there! I'm happy to help!

Let's see what we have for each variable.

I = 105

P = 100

r = 0.15

Now, let's plug it in and solve for our t (time)

105=100(0.15)(t)

Swap sides so t is on the left.

100(0.15)(t)=105

Divide both sides by 100.

0.15t=1.05

Divide both sides by 0.15

t=700

So, we see that it takes 700 months to earn this amount.

Have a wonderful day and keep on learning! :D

The number of months that it took to earn this amount will be 84 months.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where P is the principal, R is the rate of interest in percentage, and T is the time.

Samuel invested money in his bank account.

He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, R, of 0.15 per year.

At the end of the period, he had interest, I, of $105 in his account.

105 = 100 x 0.15 x t

t = 1.05 / 0.15

t = 7 years

The number of months that it took to earn this amount will be

⇒ 7 x 12

⇒ 84 months

The number of months that it took to earn this amount will be 84 months.
