Step-by-step explanation:

7:18:11

total ratio=7+18+11

=36

The smallest angle(a)

7/36 x s=35

7s/36=35

7s=35x36

7s=1260

7s/7=1260/7

s=180°

second angle (b)

18/36x180

=90°

What is the solution for x in the equation?<br> -x + 3/7 = 2x - 25/7
Pachacha [2.7K]

Answer:

x= 4/3

Step-by-step explanation:

Subtract 3/7 from both sides

-x= 2x-28/7

simplify

-x=2x-4

Subtract 2x from both sides

-3x=4

divide both sides by -3

x= 4/3

9) Kings Field Bank charges a monthly maintenance fee of $12 and a check
dangina [55]

Based on the monthly maintenance fee and the check writing fee, the total fees paid would be <u>$166.96</u>

<h3>Total fees paid </h3>

Alyssa will pay a total fee of:

= Yearly maintenance fee + Check writing fee

<em>= (Monthly maintenance fee x Number of months) + (Number of checks x Check writing fee)</em>

Solving gives:

= (12 x 12) + (287 x 0.08)

= 144 + 22.96

= $166.96

In conclusion, the total fees was $166.96.

Please explain and answer ​
krek1111 [17]

Step-by-step explanation:

v \:  =  \: \pi \:  {r}^{2}  \times \frac{h}{3}

rearrange to get

48\pi \:  =  \: \pi {r}^{2}  \times \frac{9}{3}

remove pi from both sides

48 \:  =  {r}^{2}  \:  \times 3

\frac{48}{3}  =  {r}^{2}

16 =  {r}^{2}

r =  \sqrt{16}

r = 4

List the angles of triangle PQR from smallest to largest
Norma-Jean [14]
So in order for us to know which angle is the smallest and which one is the largest, take note that the largest angle is the opposite of the longest side, and the smallest angle is the opposite of the shortest side. So base on the given figure above, the smallest angle would be angle p, then next is angle q and the largest, therefore would be angle r. Hope this answer helps. So it is p,q,r.
