If y varies directly as x, and y =6 when x =10, find x when y=18

Answers

Answer:

X=30

Step-by-step explanation:

y=kx

6=10k

k=0.6

y=0.6x

18=0.6x

X=18/0.6

x=30

The value of x when y = 18 is 30.

What is Direct Variation?

Direct variations are defined as the functions of the form y = kx, where k is a constant.

Here when y increases, x increases and if y decreases, x also decreases.

Given that y varies directly as x.

That is the equation relating y and x can be written as,

y = kx, for some constant k.

Given that,

When x = 10, the value of y = 6.

Substitute in the equation.

6 = 10k

k = 6/10 = 3/5

Now we have to calculate the value of x when y = 18.

Substitute the found values and given values in the equation.

18 = (3/5) x

x = (18 × 5) / 3

x = 30

Hence the value of x is 30 when y = 18.

20 muffins =

220 ÷ 20 = 11 (milk)

250 ÷ 20 = 12.5 (castel sugar)

400 ÷ 20 = 20 (flour)

Find out the greatest number of muffins Jack can make.

1 litre = 1000 ml

On Monday Sylvia spent 5/12 of a day driving to her cousins house. On Friday she spent the same amount of time driving home. What fraction of a day did Sylvia spend driving to her cousins house and back?

Answers

Answer: The fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Step-by-step explanation:

Given: Fraction of day Sylvia spent to drive her cousins home = [tex]\dfrac5{12}[/tex]

Fraction of day Sylvia spent to drive her home back= [tex]\dfrac5{12}[/tex]

Total fraction of day Sylvia spend driving to her cousins house and back = [tex]\dfrac5{12}+\dfrac{5}{12}[/tex]

[tex]=\dfrac{5+5}{12}\\\\=\dfrac{10}{12}\\\\=\dfrac{5}{6}[/tex]

Hence, the fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.



At the end of 6 years, the balance was $3,025. What is the interest rate on this account?

Answers

The percent is 5.25%

The interest rate on Mia's account is 20.17%.

What is the simple interest?

The borrowing amount is just the principal amount multiplied by the simple interest rate.

Given, Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.

The formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

We have, P = $2500 T = 6 years, S.I. = $3025

Substituting all the values in the formula;

3025 = 2500 x 6 x R / 100

R = 3025 x 100 / 15000

R = 20.17%

Therefore, the interest rate is 20.17%.
