Based on the amount that Cameron invests in the bank account that gathers interest each month, the amount in the account after 2 years and 7 months is £4,777.81
How to find the amount in the account?The number of periods in months is:
= 2 years and 7 months

The periodic interest in months is:
= 5% / 12 months
= 5/12%
The amount in the bank account after 2 years and 7 months is:

A zucchini plant in Darnell's garden was 10 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeters per day. a. Write a rule to describe the function. b. After how many days will the zucchini plant be 0.185 meters tall?
Answers
a) g(x) = 10 + 0.5x
b) 17 days
Explanations:Let the number of days be represented by x
Let the intial height of the zucchini plant be g₀
g₀ = 10 cm
Size of growth per day = 0.5 cm
Let the growth after x days be represented by g(x)
a) The rule that represents the function is therefore:
g(x) = g₀ + 0.5x
g(x) = 10 + 0.5x
b) After how many days will the Zucchini pant be 0.185 meters tall
That is g(x) = 0.185 meters
since 1 meter = 100 cm
g(x) = 0.185 x 100 cm
g(x) = 18.5 cm
Thereofre substitute g(x) = 18.5 into the equation g(x) = 10 + 0.5x
18.5 = 10 + 0.5x
18.5 - 10 = 0.5x
0.5x = 8.5
x = 8.5 / 0.5
x = 17
The zucchini plant will be 0.185 meters tall after 17 days

We are told that the side length of the cube is 1/8 of an inch. Furthermore, we are also told that the rectangular prism fits 16 cubes along the length, 8 cubes along the width, and 6 cubes along the height. This means the measures of the dimensions of the prism are

On a given planet the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 80 KG weighs 80 n calculate the mass of another object that weighs 70 n
Answers
We are told that the weight of an object varies directly with the mass of the object. This basically means that if w is the weight and M is the mass then these two magnitudes are related by the following expression:
[tex]w=k\cdot M[/tex]Where k is a constant.
We know that an object with a mass of 80kg weights 80 newtons. Then for this object we have w=80kg and M=80n so we get:
[tex]80n=k\cdot80kg[/tex]We divide both sides of this equation by 80:
[tex]\begin{gathered} \frac{80n}{80}=\frac{k\cdot80kg}{80} \\ 1n=k\cdot1kg \end{gathered}[/tex]Here it's important to remember that 1 newton (i.e. 1n) is equal to:
[tex]n=\frac{kg\cdot m}{s^2}[/tex]Then we get:
[tex]1\frac{kg\cdot m}{s^2}=k\cdot1kg[/tex]We divide both sides by 1 kg:
[tex]\begin{gathered} \frac{1\frac{kg\cdot m}{s^2}}{1kg}=\frac{k\cdot1kg}{1kg} \\ 1\frac{kg\cdot m}{kg\cdot s^2}=k\cdot\frac{1kg}{1kg} \\ k=1\frac{m}{s^2} \end{gathered}[/tex]So now that we found k we have the following expression for the weight of an object as a function of its mass:
[tex]w=M\cdot1\frac{m}{s^2}[/tex]For an object that weights 70n we get:
[tex]\begin{gathered} 70n=M\cdot1\frac{m}{s^2} \\ 70\frac{kg\cdot m}{s^2}=M\cdot\frac{m}{s^2} \end{gathered}[/tex]We divide both sides by 1 m/s²:
[tex]\begin{gathered} \frac{70\frac{kg\cdot m}{s^2}}{1\frac{m}{s^2}}=\frac{M\cdot\frac{m}{s^2}}{1\frac{m}{s^2}} \\ 70\frac{kg\cdot m\cdot s^2}{m\cdot s^2}=M\cdot\frac{m\cdot s^2}{s^2\cdot m} \\ 70kg=M \end{gathered}[/tex]AnswerSo the mass of an object that weights 70n is 70kg.

His monthly payments will be $771. Because Lauren has a lower credit score, she will have to pay an interest rate of 3.7% per year. Her monthly payments will be $840. How much more will a $90,000 loan cost Lauren than Demarcus?
Answers
The amount that a $90,000 loan cost Lauren than Demarcus will be $8280.

= 10 × 12 = 120 months
The difference in the amount paid as a result of the credit score will be:
= ($840 × 120) - ($771 × 120)
= $100800 - $92520
= $8280
Therefore, the amount is $8280.

Answer:
Safe fund = $24,000
Risky fund = $6,000
Step-by-step explanation:
Definition of variables:
Let x = the amount of money invested in the safe fund.Let y = the amount of money invested in the risky fund.Given information:
Safe fund = 2.5% annual interest.Risky fund = 8% annual interest. Total interest earned at the end of one year = $1080.The amount of money invested in the safe fund, x, is to be exactly four times the amount invested in the risky fund, y.Convert the percentages into decimal form:
[tex]\implies 2.5\%=\dfrac{2.5}{100}=0.025[/tex]
[tex]\implies 8\%=\dfrac{8}{100}=0.08[/tex]
Create a system of equations from the given information and defined variables:
[tex]\begin{cases}0.025x+0.08y=1080\\x=4y\end{cases}[/tex]
Substitute the second equation into the first equation and solve for y:
[tex]\implies 0.025(4y)+0.08y=1080[/tex]
[tex]\implies 0.1y+0.08y=1080[/tex]
[tex]\implies 0.18y=1080[/tex]
[tex]\implies \dfrac{0.18y}{0.18}=\dfrac{1080}{0.18}[/tex]
[tex]\implies y=6000[/tex]
Substitute the found value of y into the second equation and solve for x:
[tex]\implies x=4(6000)[/tex]
[tex]\implies x=24000[/tex]
