Sophia earned $240 at her brother's store. If she worked for 8 days and earned the same amount of money each day, how much did she earn per day?

Answers

Answer 1
Answer:

Answer:

$30

Step-by-step explanation:

$240 divided by 8

She earns $30 each day
Answer 2
Answer: 8x=240

Where 8 is the amount of days, 240 is the total pay, and x represents the pay per day.

8x=240
—- ——
8 8

In this step, you are dividing both sides by 8 to isolate the x

x=30

Therefore, she was paid $30 each day. You can check this by inserting back into your equation.

8(30)=240
240=240

Hope this helps!

What is the value of the expression (0.5)4 ?

Answers

The value of the expression (0.5)^4 is 0.0625.

In this expression, (0.5) raised to the power of 4 means that you multiply 0.5 by itself four times.

So, it would be calculated as 0.5 x 0.5 x 0.5 x 0.5, which equals 0.0625.

When you raise a number less than 1 to a positive exponent, like in this case, the result is a smaller number because you are repeatedly dividing the original number by itself, which makes it smaller each time.

In this case, 0.5 is divided by itself four times, resulting in a much smaller value, 0.0625.

To explain further, exponentiation represents repeated multiplication. When you raise a number to an exponent, you are essentially multiplying that number by itself the specified number of times.

In this case, (0.5)^4 means multiplying 0.5 by itself four times, leading to the value 0.0625.

This concept is fundamental in mathematics and is used in various applications, including calculating compound interest, population growth, and many scientific calculations where values change over time or with repetition.

XYZW is a parallelogram with diagonals and that intersects at point A if YA=2t WA=3t-4 and XZ=5t find XA​

Answers

Answer:

  • XA = 10 units

Step-by-step explanation:

Given parallelogram XYZW with:

  • XZ and YW intersect at point A.
  • YA = 2t
  • WA = 3t - 4
  • XZ = 5t
  • XA = ?

First, the diagonals bisect each- other:

  • YA = WA

Substitute values and solve for t:

  • 2t = 3t - 4
  • 3t - 2t = 4
  • t = 4

Find the diagonal XZ:

  • XZ = 5t = 5*4 = 20

Find the length of XA:

  • XA = XZ / 2 = 20 / 2 = 10

As Diagonals bisect each other in parallelogram

  • YA=WA
  • 2t=3t-4
  • 3t-2t=4
  • t=4

Diagonal XZ

  • 5t
  • 5(4)
  • 20

3x + 6y = -18
2y = 3x - 22
The solution to the system is ( ___, ___ ).

Answers

Answer:

(4, -5)

Step-by-step explanation:

3x + 6y = -18

2y = 3x - 22

In the second equation, move 3x to the other side:

3x + 6y = -18

-3x + 2y = -22

Since they have opposite signs, the x terms can cancel out. Add together the equations in order to cancel out x:

3x + 6y = -18

-3x + 2y = -22

8y = -40

Solve for y:

y = -5

Then, plug in -5 in as y into one of the equations, then solve for x:

3x + 6y = -18

3x + 6(-5) = -18

3x - 30 = -18

3x = 12

x = 4

So, the solution to the system is (4, -5)
