Answer:

X + Y = 1 ------1

X - 2y = 4 ------2

Solving by substitution method

X = 4 + 2y -----3

Putting the value of X in equation 1

4 + 2y + y = 1

4 + 3y = 1

3y = 1 - 4

3y = (-3)

y = (-3) /3

Putting value of y in equation 3

X = 4 + 2(-1)

X = 4 - 2

A. A 5in radius ball is in a

abruzzese [7]

Answer:

52.33%

Step-by-step explanation:

Since, all six sides of the box are touching the ball.

So, all the three dimensions of the box are equal.

Hence, it is a cubical box.

Side length of the box (l)

= diameter of the ball

= 2*radius of the ball

= 2*5

= 10 In.

$V_{ball} = \frac{4}{3} \pi r^3$

$V_{ball} = \frac{4}{3} \times 3.14(5)^3$

$V_{ball} = \frac{4}{3} \times 3.14\times 125$

$V_{ball} = \frac{1,570}{3}\: In^3$

$V_{box} =l^3$

$V_{box} =(10)^3$

$V_{box} =1000\: In^3$

Percentage of the space in the box occupied by the ball

$= \frac{V_{ball}}{V_{box} } \times 100$

$= \frac{\frac{1,570}{3}}{1000} \times 100$

$= \frac{1570}{3000} \times 100$

$= \frac{157}{3}$

$= 52.33\%$

What is this help please ?

stiks02 [169]

|k - 2| * |3k| - 1
Substitute all of the "k" variables for -4
|-4 - 2| * |3(-4)| - 1
Multiply 3 by -4
|-4 - 2| * |-12| -1
Subtract 2 from -4
|-6| * |-12| - 1
Use the absolute value method
6 * 12 - 1
Combine like terms
Final Answer: 71

Pls help???? b isn’t right

spayn [35]

The correct answer would be A

Take the left triangle, flip it and put it on the right side. This should resemble a rectangle. Then calculate

9cm + 7cm = 16cm
6cm x 16cm = 93cm squared

The correct answer is A, hoped this helped!

Goshia [24]

It looks to be D but if you still need help I'd recommend checking out Desmos sure it is a graphing calculator but it may be easier to understand it with that.
