Answer:

Perimeter of a square

Step-by-step explanation:

The formula for finding out the perimeter of a square is P = 4s

Answer:

a) a1=15 first term

b) d=-8 common difference

Step-by-step explanation:

1)a1+d=7

2)a1+a2+a3+a4=12

a1+a1+d+a1+2d+a1+3d=12

4a1+6d=12

2a1+3d=6

We have the system of equations where a1+d=7 and 2a1+3d=6

3a1+3d=21

2a1+3d=6

Subtract the second equation from the first one

a1=15

d=-8

First term = 15

Common difference = -8

Let the first term be a and common difference be d.

Therefore,

a+d = 7       -     eq. 1

a+(a+d)+(a+2d)+(a+3d) = 12      -    eq. 2

4a + 6d = 12

4a + 4d + 2d = 12

Dividing both sides by 2,

2a + 2d + d = 6

2 (a+d) + d = 6

Substituting value of (a+d) in the above equation,

2*7 + d = 6

d = 6 - 14

d = -8

Substuting value of d in eq. 1

a+d = 7

a + (-8) = 7

a = 7 + 8

a = 15

Answer:

125 inches

Step-by-step explanation:

In one minute caterpillar crawls 25 inches. So in 5 minutes we have 5 times 25 inches is 125 inches.

By equation

Additional: 25 + 25 + 25 + 25 + 25 = 125 (inches)

Mutiplication: 25 * 5 = 125 (inches)

The caterpillar crawls 125 inches in 5 minutes

because it is said that the caterpillar crawls 25 inches in one minute so we can use multiplication 25 x 5 = 125

Answer: 120 m/min or 2 m/s

Concept:

Here, we need to know how to calculate velocity.

Velocity = ΔD / ΔT

The SI unit of velocity is m/s

Solve:

Given information

Distance = 1200 m

Time = 10 min

Given expression

Velocity = ΔD / ΔT

Substitute values into the expression

Velocity = 1200 / 10

Velocity = 120 m/min

Extra:

**Disclaimer** Ignore this part if it is irrelevant to what you are learning.

If the question needs an answer with SI unit, then please see below:

Given information

Distance = 1200 m

Time = 10 min = 10 × 60 = 600 sec

Given expression

Velocity = ΔD / ΔT

Substitute values into the expression

Velocity = 1200 / 600

Velocity = 2 m/s

Step-by-step explanation:

Gross income is: The total amount of earned salary or wages. Option C is the correct answer.

Gross income refers to the total amount of money earned by an individual before any deductions or taxes are taken out. It represents the complete earnings from employment or other sources of income before any adjustments or deductions are made.

Gross income includes the full amount of salary or wages earned by an individual, as well as any additional income such as bonuses, commissions, or tips.

Option A is incorrect because gross income is the total amount earned before tax and benefit deductions are applied.

Option B is incorrect because gross income is not after tax, but rather before any tax deductions.

Option D is incorrect because gross income does not specifically refer to the amount withheld for taxes, but rather the total amount earned before any deductions.

Answer:

x = 35

Step-by-step explanation:

Co interior angle sum to 180° , so

x + 30 + 3x + 10 = 180 , that is

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

Step-by-step explanation:

Those straight lines that look like this -> |

Represent absolute value.

All absolute value means is the distance a number is from zero.

For example: -2 is 2 numbers away from zero.

5 is 5 numbers away from zero.

-7 is 7 numbers away from zero.

So when something says |-7| that is the same value as 7

So 7 = 7

NOT 7>7 (that doesn't make sense)
