how do you convert percentages into decimals??

Answers

Answer:

Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.

Example: 10% becomes 10/100 = 0.10.

Example: 67.5% becomes 67.5/100 = 0.675.

A rectangular window is 4x inches wide and 8x inches long. What is an expression for the distance from one corner of the window to the opposite
corner? Give your answer as a simplified radical.

Answers

Answer:

Step-by-step explanation:

Pythagorean theorem

a² + b² = c²          a = 4x     b=8x

c = √(a² + b²)

c =√((4x)² + (8x)²)

  = √(16x² + 64x²)

  = √80x²

  = √(16×5)x²

  = 4x√5

​For the two right triangles above, explain why a/8=x/12 . ​ ​What ​trigonometric ratio is also equal to the two given ratios?

Answers

Answer:

sin trigonometry ratio

Step-by-step explanation:

Given

See attachment for triangles

Required

Explain why [tex]\frac{a}{8} = \frac{x}{12}[/tex]

From the attached diagram, both triangles are similar triangles because

(1) the second triangle is a dilation of the first triangle by a ratio of 1.5

i.e

[tex]k = \frac{12}{8}[/tex]

[tex]k = 1.5[/tex]

(2) They have angle 30 degrees, and have their right angles located at the same point

In the first triangle, the sine of 30 degrees is represented as:

[tex]sin(30) = \frac{Opp}{Hyp}[/tex]

This gives:

[tex]sin(30) = \frac{a}{8}[/tex]

In the second triangle:

[tex]sin(30) = \frac{Opp}{Hyp}[/tex]

So:

[tex]sin(30) = \frac{x}{12}[/tex]

By comparison:

[tex]sin(30) = sin(3)[/tex]

Hence:

[tex]\frac{a}{8} = \frac{x}{12}[/tex]

Billy and Susie were saving up to buy the new Xbox. Billy got $50 for his birthday and saved $20 each week. Susie already had $25 and saved $40 each week. Write a system of equations to describe this situation.

Answers

Answer:

50+ 20x= y

25+ 40x= y

Explanation:

For Billy and Susie, the starting values are $50 and $25. You simply add that to the money saved per week ($20 and $40).

x= number of weeks

I’m not quite sure but what about...

Billy —> $50 + $20 * x
Susie—>$25 +$40 * x

I’m not sure how to continue though. My apologies if this is incorrect.
