Answer:

Since 10/9 is greater than 1, multiplying by 10/9 makes the value larger

Step-by-step explanation:

Step 1: Solve the fraction

10/9 = 1.1112

Therefore 10/9 > 1

Step 2: Multiple the fraction by itself

10/9 x 10/9 = 100/81

Convert fraction to decimals

100/81 = 1.2345678901.....

1.234567901 > 1.1112

Therefore 10/9 x 10/9 is bigger than 10/9

Logan is getting a second dog and wants to increase the length of the play space by 3 feet and the width by 3 feet. What will be

alexgriva [62]

Answer:

$(3x+3y+9)\ ft^{2}$

Step-by-step explanation:

Let

x------> the length of the original play space

y-----> the width of the original play space

we know that

The area of the original play space is equal to

$A=xy$

The area of the new play space is equal to

$An=(x+3)(y+3)\\An=xy+3x+3y+9$

Find the difference

$An-A=(xy+3x+3y+9)-(xy)\\An-A= (3x+3y+9)\ ft^{2}$

What is the best approximation of the surface area of this right cone

Tatiana [17]

Use the formula for the surface area of a right cone:

$\sf A=\pi rs+\pi r^2$

Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):

$\sf A=(3.14)(12)(15)+(3.14)(12)^2$

Multiply and simplify exponent:

$\sf A=565.2+(3.14)(144)$

Multiply:

$\sf A=565.2+452.16$

Add, round to the nearest whole number:

$\boxed{\sf A\approx 1017~cm^2}$

What i the constant of proportionality in the equation y - 2.5x?

ELEN [110]

2.5 because if you move x to the other side of the equation you will get y=2.5x, and the constant of proportionality is what x is multiplied by, in this case, it's 2.5.

Which equation represents the graph of the linear function?

Flura [38]

Since the line is going from the top left to the bottom right, the slope is negative so A and B are possible answers.

the line crosses the y axis at -1
B is the option that ends with -1

therefore your answer is B. y = -2x - 1
