Answer:

Perimeter = 46.6 m

Area = 78.36 m²

Step-by-step explanation:

Perimeter is just the outsides, so add 3.7 + 12.3 + 4.5 +11 AND the sides you aren't given. To find them, you do 11-3.7 = 7.3 and 12.3-4.5 = 7.8. So you add 3.7 + 12.3 + 4.5 + 11 + 7.3 + 7.8 = 46.6

Area is the inside, so you multiply length by width. You can split it different ways, but I multiplied by 3.7*12.3 first, giving 45.51. Now to find the area of the other box, you need to subtract 11 by 3.7, which we saw was 7.3. Now we can multiply 7.3 by 4.5, which is 32.85. Then you add 45.51 and 32.85 to get 78.36.

Aleksandr-060686 [28]

Answer:

238882 -> 238881

Step-by-step explanation:

If you can, please leave an explanation so I can learn how to do it rathe than just copying
castortr0y [4]

Answer:

Point-Slope: y+1=-5/7(x-5)

Slope Intercept: y=-5/7x+ 2 4/7

Standard: -5x+7y=18

Step-by-step explanation:

<u>Slope: -5/7</u>

Point slope is when the equation is in y-y1=m(x-x1) form.

I used the point (5,-1) but it really <u>doesn't matter</u> which one

Substitute it into (x1,y1)

y--1=-5/7(x-5)

y+1=-5/7(x-5) **2 minus signs is equal to 1 plus sign**

Slope-intercept is when the equation is in y=mx+b form.

y=-5/7x+b

To solve for b, plug in one of the points (again, I choose to use (5,-1)

(-1)=-5/7(5)+b

-1=-25/7+b is equal to asking -1=-3 4/7+b

b=2 4/7

Standard form is when it is in Ax+By=C

We'll covert from slope intercept to standard: y=-5/7+ 2 4/7

y=-5/7x+ 2 4/7 is the same as y=(-5/7x+ 18/7)

7y=5x+18 **Multiply both sides by 7, the common denominators**

-5x+7y=18 **Subtract 5x from both sides**

Assuming that n 1 , rewrite the compound interest equation B t 900 1.185 t in the general form.
Rufina [12.5K]
\bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}&#10;\quad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{original amount deposited}\\&#10;r=rate\to r\%\to \frac{r}{100}\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}&#10;\end{array}\\&#10;t=year&#10;\end{cases}

\bf 1.185\implies 1+0.185\qquad\quad and\quad n=1&#10;\\\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}\implies A=P\left(1+0.185\right)^{nt}\implies A=P\left(1+\frac{0.185}{1}\right)^{1\cdot  t}

so, the percentage of the rate is 0.185, what's that as a percentage? well, 0.185 * 100, 18.5%.
