Work out the value of x

Mathematics
1 answer:
zalisa [80]3 years ago
3 0

Answer:

x = 67.5°

Step-by-step explanation:

A circle's angles add up to 360°

So,

x+3x+90 = 360

4x+90 = 360

4x = 360-90

4x = 270

Dividing both sides by 4

x = 67.5°

Christopher estimates it will take him half an hour to complete his math homework. He is able to complete it in 25 minutes. What
marin [14]

Answer:

The percent error in his estimate is<u> 16.67%</u>.

Step-by-step explanation:

Given:

Christopher estimates it will take him half an hour to complete his math homework.

He is able to complete it in 25 minutes.

Now, to find the percent error  in his estimate.

Time estimates of completing homework = 30 minutes.

Time actual taken to complete homework = 25 minutes.

Error in estimate = Time estimates of completing homework - Time actual taken to complete homework.

Error in estimate = 30 minutes - 25 minutes.

Error in estimate = 5 minutes.

Now, to get the percent error:

Percent\ error =\frac{Error\ in\ estimate}{Time\ estimates\ of\ completing\ homework} \times 100.

Percent\ error=\frac{5}{30} \times 100

Percent\ error=\frac{500}{30}

Percent\ error=16.67\%.

Therefore, the percent error in his estimate is 16.67%.

The diagram below represents which percent?
nirvana33 [79]

Answer:

80%

Step-by-step explanation:

There are 4 shaded sections and 1 unshaded section, so five sections in total.

4 sections are shaded, so the fraction would be 4/5.

Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
