You start off with (x)+(3x)=3675, so you can find the value of x, so you combine to create 4x=3675. then you divide 3675 by 4 to get x=918.75. then you plug them into the equations to find your numbers.

so the numbers are 918.75, and 2756.25

Answer:

Option A is correct.

Step-by-step explanation:

No of Balls in Basketball = 2

No of Balls in Dodge ball = 18

No of Balls in Soccer ball = 8

No of Balls in Tennis ball = 14

$\frac{No.\:of\:Soccer\:ball}{No.\:of\:Tennis\:ball}=\frac{8}{14}=\frac{4}{7}$

Ratio of Soccer balls to Tennis balls = 4 : 7

⇒ For every 4 Soccer ball, there are 7 Tennis ball.

$\frac{No.\:of\:Basket\:ball}{No.\:of\:Dodge\:ball}=\frac{2}{18}=\frac{1}{9}$

Ratio of Basket ball to Dodge Ball = 1 : 9

⇒ For every 1 Basket ball, there are 9 Dodge balls.

Therefore, Option A is correct.

Answer:

$a.\ \ \ A=684\ m^2$

$b.\ \ \ A=130.2 \ km^2$

Step-by-step explanation:

a. Area is calculated by summing the areas of the prism's individual surfaces.

#First, calculate the areas of the right-angled surfaces:

$Area=2(\frac{1}{2}bh), b=9, h=12\\\\=2\times \frac{1}{2}\times 9\times 12\\\\=108\ m^2$

#We then find the areas of the rectangular surfaces:

$A=lw\\\\=15\times 16+9\times 16+16\times 12\\\\=576\ m^2$

#We sum the areas to find the total surface areas:

$A=\sum{Areas_i}\\\\=108+576\\\\=684\ m^2$

Hence, the prism's surface area is $684\ m^2$

b.Area is calculated by summing the areas of the prism's individual surfaces.

#First, calculate the areas of the right-angled surfaces:

$A=2\times \frac{1}{2}bh,\ b=12, h=4.1\\\\=2\times 0.5\times 12\times 4.1\\\\=49.2 \ km^2$

#We then find the areas of the rectangular surfaces:

$A=lw\\\\=5\times 3+3\times 10+12\times 3\\\\=81\ km^2$

#We sum the areas to find the total surface areas:

$A=A_r+A_t\\\\=81+49.2\\\\=130.2 \ km^2$

Hence, the prism's surface area is $130.2 \ km^2$
