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 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%.

jack finds this list of ingridents needed to make 20 muffins. To make 20 muffins you need 220ml milk, 250g castel sugar, 400g flour.
Jack has these ingridents : 1 litre of milk, 750g caster sugar and 1.5kg flour. Work out the greatest number of muffins Jack can make with his ingridents!
Answers
Answer:
60 muffins
Step-by-step explanation:
Find out how much ml you need for each ingredient.
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
1000 ÷ 11 = 90.90 (recurring decimal) (milk)
750 ÷ 12.5 = 60 (castel sugar)
1500 ÷ 20 = 75 (flour)

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.

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]
1. Write the equation that models the height of the roller coaster. Start by writing the equation of the circle. (Recall that the general form of a circle with the center at the origin is x2 + y2 = r2. (10 points) Now solve this equation for y. Remember the roller coaster is above ground, so you are only interested in the positive root. (10 points)
Answers
Answer:
a.)x² + y² = 900
b.)y = √900 - x²
Step-by-step explanation:
P.S - The exact equation is as follows :
As given,
The shape of the roller coaster is a half of a circle. Center the circle at the origin and assume the highest point on this leg of the roller coaster is 30 feet above the ground.
a.)
Equation of circle be x² + y² = r²
As given , leg of the roller coaster is 30 feet above the ground.
⇒ r = 30
⇒x² + y² = 30²
⇒x² + y² = 900
∴ we get
Equation of height of Roller coaster - x² + y² = 900
b.)
As we have, x² + y² = 900
⇒y² = 900 - x²
⇒y = √900 - x²
The equation that models the height of the roller coaster is [tex]y = \sqrt{900 -x^2[/tex]
The general equation of a circle is:
[tex]x^2 + y^2 = r^2[/tex]
From the complete question, the radius of the circle is 30 units.
This means that:
r = 30
So, we have:
[tex]x^2 + y^2 = 30^2[/tex]
Express 30^2 as 900
[tex]x^2 + y^2 = 900[/tex]
Subtract x^2 from both sides
[tex]y^2 = 900 -x^2[/tex]
Take square roots of both sides
[tex]y = \pm \sqrt{900 -x^2[/tex]
Remove the negative root
This is so because the roller coaster is above the ground, and the height will be positive.
So, we have:
[tex]y = \sqrt{900 -x^2[/tex]
Hence, the required equation is [tex]y = \sqrt{900 -x^2[/tex]
