Step-by-step explanation:

Hope that helps!

Answer 2

The equation in option (b), 2/5 + 1/4 = 13/20, uses the commutative property of addition to rewriting 1/4 +2/5.

What is the commutative property of addition?

The sum of two or more integers remains the same regardless of how they are grouped, according to the commutative property of addition.

The given expression is 1/4 + 2/5.

Simplify the expression as follows:
1/4 + 2/5

= (5 + 8)/20

= 13/20

Hence, it follows 1/4 + 2/5 = 13/20.

Now, using the commutative property of addition, the equation can be written as:

2/5 + 1/4 = 13/20

Hence, the equation in option (b), 2/5 + 1/4 = 13/20, uses the commutative property of addition to rewriting 1/4 +2/5.

Answer:

Step-by-step explanation:

The growth factor is 1 -8% = 0.92. This is the base of the exponential formula. The multiplier is the initial value, so you have ...

  p = 8951×0.92^t

When t=30, this evaluates to ...

  p = 8951×0.92^30 ≈ 733.68

A bricklayer lays 1200 bricks in an average 8-hour day. How many bricks does he lay in a 40-hour week?

Answers

The answer is 6000 bricks.
40/8=5
5*1200=6000

The number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

Let the number of bricks that the bricklayer can lay in a 40-hour week be represented by x.

Based on the information given in the question, the equation to solve the question will be:

8/40 = 1200/x

Cross multiply

8 × x = 1200 × 40

x = (1200 × 40) / 8

x = 1200 × 5

x = 6000

Therefore, the number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

does anyone know how to do this ?

Answers

9514 1404 393

Answer:

  y = 21

Step-by-step explanation:

In straightforward fashion, we can find the midpoints of the two segments, and set the distance between them equal to 10.

  M = midpoint of AB

  M = (A+B)/2 = ((-1, 0) +(-3, 6))/2 = (-4, 6)/2 = (-2, 3)

  N = midpoint of CD

  N = (C+D)/2 = ((3, 1) +(5, y))/2 = (8, 1+y)/2 = (4, (1+y)/2)

Then the distance MN is given by the distance formula.

  |N-M| = 10 = √((4 -(-2))² +((1+y)/2 -3)²) . . . . . distance formula*

  100 = 36 +((1+y)/2 -3)² . . . . . square both sides

  64 = ((1 +y)/2 -3)² . . . . . . . . . subtract 36

  8 = (1 +y)/2 -3 . . . . . . . . . . . . (positive) square root

  11 = 1+y/2 . . . . . . . . add 3

  22 = 1+y . . . . . . . . . multiply by 2

  21 = y . . . . . . . . . . . subtract 1

_____

* The distance formula is an application of the Pythagorean theorem. Basically, the differences of x- and y-coordinates are taken to be the legs of a right triangle. They length of the hypotenuse is the distance between the two points.

  d² = (x2 -x1)² +(y2 -y1)² . . . . . . . from the Pythagorean theorem

  d = √((x2 -x1)² +(y2 -y1)²) . . . . . the usual distance formula
