221.57
Explanation:
To round to the nearest tenth you would would look at the hundredths place. If it is higher than 5 you round the number in the tenth place up if it is lower than 5 you keep it the number in the tenth place the same. In this case you have 2 which is lower than 5 so you keep the 7 the same and bring everything else down.

In an investment account what if $2000 is invested. What is the value after 3 years if compounded monthly by 6% ?
OleMash [197]
<span>
Compound interest formula  A = P(1 +r/100)^n
A = Amount
r = rate = 6
n = number of compounding time.
P = Principal = $2000.
Since we are compounding monthly, r = 6% p.a = (6/12)% per month.
n= 3 years = 3*12 = 36 months.
Note that  since we are compounding monthly, our time would be in months.
A = P(1 +r/100)^n
A = 2000 * (1 + (6/12)/100 )^36
A = 2000 * (1 +  6/1200)^36
</span><span>A = 2000 * (1 +  0.005)^36    Use your calculator</span>
<span> <span>A = 2000 * (1 .005)^36</span> = 2393.36
Amount = $2 393.36</span>
That's it. Cheers.

Determine dois números ímpares consecutivo cujo produto seja 195
miv72 [106K]
Let 1st integer  = xLet 2nd integer = x + 1 We set up an equation. x(x + 1) = 195 x2 + x = 195 x2 + x - 195 = 0

We will use the quadratic formula: x = (-b ± √(b2 - 4ac) / (2a) x = (-1 ± √(1 - 4(-195))) / 2 x = (-1 ± √(781)) / 2 x = (-1 ± 27.95) / 2 x = 13.48x = -14.78 
<span>We determine which value of x when substituted gives us a product of 195.</span> 13.48(14.48) = 195.19-14.48(-13.48) = 195.19 <span>The solution is 2 sets of two consecutive number</span> <span>Set 1</span> The 1st consecutive integer is 13.48The 2nd consecutive integer is 14.48 
<span>Set 2</span> The 1st consecutive integer is -14.48The 2nd consecutive integer is -13.48Hopefully this helped, hard work lol :)

Which set of coordinates satisfies the equations x − 2y = -1 and 2x + 3y = 12? A. (1, 2) B. (3, 1) C. (3, 2) D. (-3, -2) E. (3,
Sindrei [870]

Answer:

(3,2)  Choice C

Step-by-step explanation:

x-2y = -1

2x+3y =12

multiply the first equation by -2

-2x +4y = 2

add the 2 equations together

2x+3y =12

-2x +4y = 2

-----------------

7y         =14

divide by 7

y =2

x-2y = -1

x -2(2) = -1

x-4 = -1

add 4 to each side

x = 3

PLS HELP! ASAP!
KATRIN_1 [288]

Answer:

Your answer is C, 10.7cm

Step-by-step explanation:

The two flat sides of the figure are 3 cm, so that part of the perimeter = 6cm

3cm is the radius of what would be a whole circle. We'll calculate the circumference, then divide by 4.

Circumference = (2)(pi)(r)

C = (2)(3.14)(3)

C = 18.84

18.84/4 = 4.71

Add 4.71 to the 6 cm above, = 10.71

Let me know if you have questions about this.
