Mathematics
1 answer:
kherson [118]3 years ago
8 0

Answer:

3

Step-by-step explanation:

A ( 2, 2 )

( x1, y1 ) = ( 2, 2 )

Here,

x1 = y1 = 2

B ( - 2, - 2 )

( x2, y2 ) = ( - 2, - 2 )

Here,

x2 = y2 = - 2

Distance formula : -

d = √ ( x2 - x1 )² + ( y2 - y1 )²

AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²

= √ ( - 2 )² + ( - 2 )²

= √ 4 + 4

AB = √8

The value of √8 is 2.828.

Roundoff to nearest 10 is 3.

Which values from the set {2, 4, 6, 8, 10) make the inequality n +5 > 10 true?
tankabanditka [31]

Answer:

6, 8, 10

Step-by-step explanation:

First, solve the inequality

To do this, we need to get n by itself

n +5 > 10

5 is being added to n. To undo this, subtract 5 from both sides, since subtraction is the opposite of addition. This will eliminate the 5 on the left side, and leave n by itself.

n+5-5 > 10-5

n > 5

So, any number greater than 5 is a solution, and will make the inequality true.

The numbers in the set that are greater than 5 are 6, 8, and 10

To test that these numbers do make the inequality true, substitute each value in for n

n +5 > 10

6+5 > 10

11 > 10

True

n +5 > 10

8+5>10

13>10

True

n +5 > 10

10+5> 10

15>10

True

A cube has a side of 5 cm. it has a mass of 250 grams. the density of the cube is
Marrrta [24]
Density = mass/volume

volume cube = side^3 = 5^3 = 125 cm^3, don't forget units!

Density = 250 grams / 125 cm^3 = 2 g/cm^3, with all the units

2/3p-14=p+13<br> How do I solve this
Aleks04 [339]
Add 14 to both sides
2/3p=p+27

Subtract p from both sides
-1/3p= 27

Multiply both sides by -3
p= -81

Final answer: p=-81
