The answer should be 1848.26 this is because you take the balance and subtract all the withdraws with it then you add all the deposits with it

Find the volume of the composite figure.First, find the volume of the cylinder.Use 3.14 for it.CylinderVolume = [?] cm9 cm9 cmCu

skad [1K]

Solution

- The question gives us a composite figure made up of a cylinder and a cube.

- We are required to find the volume of the cylinder and the cube and then use the results to find the volume of the composite figure.

- The formulas needed for this calculation are:

$\begin{gathered} Volume\text{ of Cylinder}=\pi\times r^2\times h \\ where, \\ r=radius\text{ of the cylinder} \\ h=height\text{ of the cylinder} \\ \\ Volume\text{ of Cube}=l^3 \\ where, \\ l=dimension\text{ of the cube} \\ \\ Volume\text{ of Composite figure}=Volume\text{ of Cylinder }+Volume\text{ of Cube} \\ \end{gathered}$

- With the information above, we can proceed to solve the question

Volume of the Cylinder:

$\begin{gathered} V=\pi\times r^2\times h \\ r=\frac{6}{2}=3\text{ \lparen Since 6cm is the diameter of the cylinder\rparen} \\ h=4 \\ \\ \therefore V=\pi\times3^2\times4 \\ \\ V=36\pi cm^3 \end{gathered}$

Volume of Cube:

$\begin{gathered} V=l^3 \\ l=9 \\ \therefore V=9^3=729cm^3 \end{gathered}$

Volume of Composite Figure:

$\begin{gathered} V=36\pi+729 \\ use\text{ }\pi=3.14 \\ \\ V=36\left(3.14\right)+729 \\ \\ V=842.04cm^3 \end{gathered}$

Final Answer

The volume of the composite shape is 842.04 cm³

The equation for the future value of a deposit earning compound interest is equation <img src="https://tex.z-dn.net/?f=V%28t%29%

scoundrel [369]

Answer:

Given that:

The equation for the future value of a deposit earning compound interest is equation:

$V(t) = P(1+\frac{r}{n})^{nt}$ .....[1]

where,

P = the initial deposit

t = years invested

r = rate at which interest is compounded annually

n = number of times the interest is compounded per year

As per the statement:

After 10 years, a $2,000-dollar investment compounded annually has grown to $3600.

⇒P = $2000 and V(t) = $3600

Substitute in [1] we have;

$3600 = 2000(1+\frac{r}{1})^{10 \cdot 1}$

Divide both sides by 2000 we have;

$1.8 = (1+r)^{10}$

Taking log base 10 both sides we have;

$\log_{10} 1.8 =\log_{10} (1+r)^{10}$

⇒ $0.255272505 = 10 \log_{10} 1+r$

Divide both sides by 10 we have;

$0.0255272505 =\log_{10} 1+r$

⇒ $10^{0.0255272505} = 1+r$

Simplify":

$1.06= 1+r$

Subtract 1 from both sides we have;

$0.06=r$

r = 0.06 = 6%

Therefore, 6% is the interest rate to the nearest whole-number percent

What is j equal to in 1 2/3j=15

Vladimir [108]

Answer:90

Step-by-step explanation:One solution was found :

j = 90

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

1/2/3*j-(15)=0

Step by step solution :

Step 1 :

Simplify —

Equation at the end of step 1 :

(— ÷ 3 • j) - 15 = 0

Step 2 :

Divide — by 3

Equation at the end of step 2 :

(— • j) - 15 = 0

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 6 as the denominator :

15 15 • 6

15 = —— = ——————

1 6

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

j - (15 • 6) j - 90

———————————— = ——————

6 6

Equation at the end of step 3 :

j - 90

—————— = 0

Step 4 :

When a fraction equals zero :

4.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

j-90

———— • 6 = 0 • 6

Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

j-90 = 0

Solving a Single Variable Equation :

4.2 Solve : j-90 = 0

Add 90 to both sides of the equation :

j = 90

One solution was found :

j = 90
