What is the area of this trapezoid? 10cm 5cm 12cm 1.5cm

lutik1710 [3]

Area of a trapezoid = a+b+c x h

10 + 5 +12 = 27 x h

27h = 27 x 1.5 = 40.5

Please help me with number ten and twelve

jasenka [17]

Answer: $93,\ 34^{\circ}$

Step-by-step explanation:

Given

For figure (i) both triangles are congruent

$\therefore 8x-27=4x+33\\\Rightarrow 8x-4x=33+27\\\Rightarrow 4x=60\\\Rightarrow x=15$

$\Rightarrow PQ=8x-27\\\Rightarrow PQ=93$

For figure (ii)

Two triangles WXZ and WZY are congruent

$\therefore 9x-28=5x-8\\\Rightarrow 4x=20\\\Rightarrow x=5^{\circ}\\\Rightarrow \angle YWX=2(9x-28)\\\Rightarrow \angle YWX=2(17)\\\Rightarrow \angle YWX=34^{\circ}$

Which lists show numbers ordered from least to greatest? Choose all that apply.

saw5 [17]

The answer is C. -<span>3 3/4, -2 1/4, 1 1/8

It is because the highest number in the negatives, -3 3/4, is always the lowest. Obviously if there is no negative sign it is positive. 1 1/8 is the only positive so it is the greatest. And -2 1/4 is lower that -3 3/4. So it is higher than -3 3/4 but lower than 1 1/8.

I'm sorry I'm not the best explainer, but does this help?</span>

A recursive rule for a geometric sequence is

LuckyWell [14K]

Answer:

C. $a_n=(9)(\frac{2}{3})^{n-1}$

Step-by-step explanation:

Iterative geometric sequence:

$a_n=a_1x^{n-1}$

Recursive geometric sequence:

$a_n=xa_{n-1}$

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

$a_n=(9)(\frac{2}{3})^{n-1}$

And so the answer is C.
