Whatever% of anything is just (whatever/100) * anything.

let's first convert the mixed fraction to "improper" and then divide it by 100 to make decimal.

\bf \stackrel{mixed}{8\frac{1}{4}}\implies \cfrac{8\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{33}{4}}
\\\\\\
\stackrel{\%}{\cfrac{33}{4}}\implies \cfrac{\quad \frac{33}{4}\quad }{100}\implies \cfrac{\quad \frac{33}{4}\quad }{\frac{100}{1}}\implies \cfrac{33}{4}\cdot \cfrac{1}{100}\implies \cfrac{33}{400}\implies \stackrel{decimal}{0.0825}

Assume ABC Company deposits $90,000 with First National Bank in an account earning interest at 6% per annum, compounded semi-ann
maw [93]

Answer:

Step-by-step explanation:

I'm goig to assume that the formula we need here is the following:

A(t)=P(1+\frac{r}{n})^{(n)(t)

where A(t) is the amount in the account after the compounding is done, n is the number of times per year the compounding occurs, r is the rate in decimal form, and t is the time in years.  Filling in accordingly,

A(t)=90000(1+\frac{.06}{2})^{(2)(5)} and simplifying a bit,

A(t)=90000(1.03)^{10} and simplifying a bit more,

A(t) = 90000(1.343916379) so

the amount in the account after 5 years is

A(t) = 120,952.47

Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.
Mariulka [41]

Answer:

<em>The function to represent this relationship will be:  y= \frac{15}{x}</em>

Step-by-step explanation:

y  varies inversely with  x. That means......

y= \frac{k}{x}..............................(1)  

where k is a proportional constant.

Given that, when x=3, then y=5

Plugging these values into the above equation, we will get.....

5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k

Now plugging this k=15 into equation (1).....

y= \frac{15}{x}

So, the function to represent this relationship will be:  y= \frac{15}{x}

A water balloon is 5 feet above the ground when Sally launches it into the air. Use the quadratic equation 0 = -t^2 + 4t + 5 to
rodikova [14]

Answer:

t=5\ sec

Step-by-step explanation:

we have

-t^{2} +4t+5=0

Solve the quadratic equation to find the zero's or x-intercepts

Remember that

The x-intercepts are the values of x when the value of y is equal to zero ( water balloon reach the ground)

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

-t^{2} +4t+5=0

so

a=-1\\b=4\\c=5

substitute in the formula

t=\frac{-4(+/-)\sqrt{4^{2}-4(-1)(5)}} {2(-1)}

t=\frac{-4(+/-)\sqrt{36}} {-2}

t=\frac{-4(+/-)6} {-2}

t=\frac{-4(+)6} {-2}=-1

t=\frac{-4(-)6} {-2}=5

therefore

the solution is t=5\ sec
