Adding $=[tex]15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17}$ we get 73

Option D is correct

Step-by-step explanation:

We need to find the sum of: $15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17}$

Converting mixed fractions into improper fraction

$15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17}$

$=\frac{189}{12}+\frac{149}{17}+\frac{279}{12}+\frac{429}{17}$

Taking LCM of 12 and 17 we get 204

$=\frac{189*17+149*12+279*17+429*12}{204}$

$=\frac{3213+1788+4743+5148}{204}$

$=\frac{14892}{204}$

$=73$

So, adding $=[tex]15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17}$ we get 73

Option D is correct

The lengths of the bases of the right trapezoid are 9 cm and 18 cm. The length of a longer leg is 15 cm. Find the area of the tr

finlep [7]

Firstly, we will draw figure

now, we will draw a altitude from B to DC that divides trapezium into rectangle and right triangle

because of opposite sides of rectangle ABMD are congruent

so,

DM=AB=9

CM=CD-DM

CM=18-9

CM=9

now, we can find BM by using Pythagoras theorem

$BM=\sqrt{BC^2-CM^2}$

now, we can plug values

we get

$BM=\sqrt{15^2-9^2}$

$BM=12$

now, we can find area of trapezium

$A=\frac{1}{2} (AB+CD)*(BM)$

now, we can plug values

and we get

$A=\frac{1}{2} (9+18)*(12)$

$A=162cm^2$

so, area of of the trapezoid is $162cm^2$ ..........Answer

Write the equation 9y = 12x + 0.2 in standard form. Identify A, B, and C.

lbvjy [14]

Answer: D) 60x-45y = - 1 where A = 60 , B = -45 , and c = - 1

Step-by-step explanation: Clear it : 45y=60x+1

Step 2: Isolate the constant on one side: ( -1 = -45y +60x)

step 3: A= 60 , B= - 45 , C= - 1

Miguel invests money in an account paying simple interest. He invests $170 and no money is added or removed from the investment.

stiv31 [10]

$~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$185.30\\ P=\textit{original amount deposited}\dotfill & \$170\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &1 \end{cases} \\\\\\ 185.30=170[1+(\frac{r}{100})(1)]\implies \cfrac{185.30}{170}=1+\cfrac{r}{100}\implies \cfrac{109}{100}=\cfrac{100+r}{100} \\\\\\ 109=100+r\implies \stackrel{\%}{9}=r$
