Twice a year, for all four years of college, you used your credit card to pay for books and supplies, which amounts to $516 a se

mester.
In addition to that, you charged a yearly spring break trip, which averages about $700 per trip, each of the four years.
Finally, each of the 48 months you spent as a college student, you ended up charging some eating out, entertainment, clothes, etc. After interest and making your minimum monthly payment, you end up adding a balance of $100 per month.

Answer:

$11,728

Step-by-step explanation:

Twice a year, for 4 years is 8 times

516×8 = 4128

Yearly for 4 years is 4 times

700×4 = 2800

Every month for 4 years is 48 times

100×48 = 4800

Minimum expenditure:

4128 + 2800 + 4800 = $11,728

What is the simplified value of the exponential expression 27}?<br> оооо<br> 3<br> 9<br> 1/3<br> 1/9
iVinArrow [24]

<em>Note: Your exponential expression seems a little unclear. Because 27 is not an exponential expression.</em>

<em>But, I am assuming that your exponential expression is: </em>

  • \:27^{\frac{1}{3}}

<em>The reason is that my solution would still clear your concept about this topic, no matter what the question is. </em>

<em> </em>

Answer:

The simplified value of the exponential expression is:

27^{\frac{1}{3}}=3

Step-by-step explanation:

Assuming the exponential expression

\:27^{\frac{1}{3}}

\mathrm{Factor\:the\:number:\:}\:27=3^3

=\left(3^3\right)^{\frac{1}{3}}

\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0

\left(3^3\right)^{\frac{1}{3}}=3^{3\cdot \frac{1}{3}}

=3^{3\cdot \frac{1}{3}}

=3^1

\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a

=3

Therefore, the simplified value of the exponential expression is:

27^{\frac{1}{3}}=3

If a new phone screen is 19.68 cm2 larger than your current phone screen, with the dimensions 6.1 cm and 10.8 cm, then the new p
lutik1710 [3]

Answer:

(C)85.56 cm², 12.4 cm

Step-by-step explanation:

The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

The current phone screen size has dimensions: 6.1 cm and 10.8 cm,

Area of the current phone screen size = 6.1 cm × 10.8cm

Area of the current phone screen size = 65.88 cm²

Hence, The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

= 19.68cm² + 65.88cm²

= 85.56 cm²

The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___

The is calculated as:

85.56cm²/6.9cm

= 12.4cm

Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm

Option C is correct

Find the area of the figure.
givi [52]

these are just two semi-circles, one with a diameter of 22 and the other with a diameter of 30 - 22, or 8, and therefore their radius are 11 and 4 respectively.


\bf \textit{area of a semi-circle}\\\\ A=\cfrac{\pi r^2}{2}~~,~~  \stackrel{r=11}{A=\cfrac{\pi 11^2}{2}}\implies A=\cfrac{121\pi }{2}~~,~~ \stackrel{r=4}{A=\cfrac{\pi 4^2}{2}}\implies A=8\pi \\\\ -------------------------------\\\\ \stackrel{\textit{total area of the figure}}{\cfrac{121\pi }{2}+8\pi }\implies \cfrac{121\pi +16\pi }{2}\implies \cfrac{137\pi }{2}

Need help please...answer correctly ​
Lelechka [254]

Answer:

9.09

Step-by-step explanation:

x=speed of boat

y=speed of water current

Downstream relative speed = x+y

Upstream relative speed = x-y

Distance remains the same for both upstream and downstream.

a) Distance travelled downstream = speed x time = 3(x+y)

Distance travelled upstream = speed x time = 3.6(x-y)

b) Since both distances are equal, we can write

3(x+y)= 3.6(x-y)

3x+3y = 3.6x-3.6y

6.6y = 0,6x

x=11y: y=x/11

c) Water current has speed as 1/11 times of that of boat

In percent this equals 100/11 = 9.09%
