Question 4
Use the figure below to find the value of x and y
Question 4 Use the figure below to find the value - 1

Answers

Answer 1
Answer:

Answer:

x=4, y=8

Step-by-step explanation:

step 1

Find the value of y

we know that

In the right triangle of the figure

cos(30\°)=(4√(3))/(y)

Remember that

cos(30\°)=(√(3))/(2)

so

(√(3))/(2)=(4√(3))/(y)

Simplify

y=8\ units

step 2

Find the value of x

In the right triangle of the figure

sin(30\°)=(x)/(8)

Remember that

sin(30\°)=(1)/(2)

so

(1)/(2)=(x)/(8)

x=4\ units

A student skipped a step when she tried to convert 18 hours into seconds,and she got the following incorrect result:
18 hours
60 seconds)
= 1080 seconds
1 minute
What conversion ratio did she skip in this multiple-step conversion?

Answers

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = 18* 60 minutes

                     = 1080 minutes.

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = 1080* 60 seconds

                             =  64800 seconds.

Thus, 18 hours =  64800 seconds.

As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.

22 is what percent of 100 or 22 is______ % of 100

Answers

just put 22/100
That's 22% straight off the bat
22 = x% × 100
100x = 22 × 100
x = 22%

Or just do:

22 = x% of 100
22/100 = x
22% = x
