2x+3y=11

4x+2y=10

multiple the top equation by -2

-4x-6y=-22

4x+2y=10

-4y= -12

y=3

then plug 3 for y so 2x+9=11

2x=2

x=1 and y=3

In this question the base is the traingles.

Area of a triangle is base*hight/2, so it 8*6/2= 24

Volume is 24*8(hight)=192

Answer:

1.02×10¹ = 10.2

Step-by-step explanation:

We have given a number in scientific notation as follows 1.02×10¹

We need to convert it into standard notation.

1 is in ones place, 0 is in tenths place and 2 is in hundredths place.

$1.02\times 10^1=\dfrac{102}{100}\times 10\\\\=\dfrac{102}{10}\\\\=10.2$

So, the standard notation of 1.02×10¹ is 10.2
