\sf{\pmb{ANSWER : }}

let the equation be

\sf \: 3(y + 3) - 10 = 2y + 1

\sf \: 3y + 9 - 10 = 2y + 1

\sf \:  3y - 1 = 2y + 1

\sf \:  3y -2y = 1 + 1

Geometry Select the correct answer from each drop-down menu. Given that , ° and °.
Alexxx [7]

\measuredangle BAC = 29°

Answer:

\measuredangle BOC =58°

Step-by-step explanation:

\measuredangle BDC = 29°...(Given) \\\because \measuredangle BAC = \measuredangle BDC\\(\angle 's \: subtended \: by\: same\: arc) \\\huge \purple {\boxed {\therefore \measuredangle BAC = 29°}} \\\\

Since, angle subtended on the center of the circle is twice the angle subtended on the circumference of the circle.

\therefore \measuredangle BOC =2\times \measuredangle BDC\\\therefore \measuredangle BOC =2\times 29°\\\huge \red {\boxed {\therefore \measuredangle BOC =58°}} \\

What is 8 groups of0.32?
Lelechka [254]
Okay! In order to find 8 groups of .32 you'd simply divide them. So:

[.32 ÷ 8] = .04

To check you multiply:

[8 x .04] = .32.

The answer is .04

Trapezia ABCD and PQRS are similar.<br> Find the area shaded in green.
avanturin [10]

The area shaded in green is 864 cm²

<h3>Similar figures</h3>

Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,

AB / PQ = CD / RS

30 / 10 = 24 / RS

30RS = 240

RS = 240 / 30

RS = 8 cm

let find the height of trapezium PQRS.

AB / PQ  = 36 / h

30 / 10 = 36 / h

30h = 360

h = 360 / 30

h = 12 cm

Therefore,

area of the green portion = area of ABCD - area of PQRS

<h3>Area of a trapezium</h3>
  • area = 1 / 2(a + b)h

Therefore,

area of ABCD = 1 / 2(24 + 30)36 =  1 / 2 (54)36 = 1944 / 2 = 972 cm²

area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²

Area of the green portion = 972 - 108 = 864 cm²
