Answer: $312.5\ cm^2$

Step-by-step explanation:

Given

A and B are two similar shape with lengths of 12 cm and 15 cm

A has an area of $200\ cm^2$

For similar figures, ratio of the square of corresponding length is equal to the ratio of the area

$\Rightarrow \dfrac{200}{A_b}=\dfrac{12^2}{15^2}\\\\\Rightarrow A_b=\dfrac{15^2}{12^2}\times 200\\\\\Rightarrow A_b=312.5\ cm^2$

Find a5, when a1 =4, r=5

sasho [114]

Answer:

Answer: a5 = 2500

Step-by-step explanation:

For a geometric sequence:

First term = a0

Second term = a1 = a0*r

Third term = a2 = a0*r^2

Fourth term = a3 = a0*r^3

....

nth term = a(n-1) = a0*r^(n-1)

Given: a1 = 4 = a0*r

Also: r = 5

So, a0*5 = 4 => a0 = (4/5)

a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500

Hope this helps

correct me if im wrong☺

This one also thx PLZZ be right

nydimaria [60]

Answer:

D. x = 2

Step-by-step explanation:

$\frac{1}{2} x+3=\frac{5}{2} x-1$

$\frac{1}{2} x-\frac{5}{2 }x=-1-3$

$-\frac{4}{2} x=-4$

$-\frac{4}{2} x (-\frac{2}{4} )=-4(-\frac{2}{4} )$

$x = -4(-\frac{2}{4} )$

$x=2$
