Travka [436]3 years ago
7 0

Answer:

No, it's not a counterexample, because 48 is a multiple of 8

Step-by-step explanation:

I think like 4 x 3 + 8 x 2 = 28 is a counterexample, because 28 is not a multiple of 8.

Given: circle k(O), ED diameter, m∠OEF=32°, m EF=(2x+10)°. Find: x
Snezhnost [94]

Answer:

The value of x is 53\°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

so

m

we have

m

substitute

32\°=\frac{1}{2}(arc\ DF)\\ arc\ DF=64\°

step 2

Find the measure of x

we know that

arc\ DF+arc\ EF=180\° ---> is a semi circle

we have

arc\ DF=64\°\\ arc\ EF=(2x+10)\°

substitute

64\°+(2x+10)\°=180\°\\ 2x\°=180\°-74\°\\ 2x\°=106\°\\ x=53\°

OlgaM077 [116]
First, add the 3 and the 1 to get 4. Then, add the 8/9 to the 2/9 getting 10/9. Then simplify it to 1 1/9. Then add the 4 to get 5 1/9

Jason and his friend went to a restruant for dinner. The food that they ordered cost $25. A 7℅ sales tax was applied to the tota
Westkost [7]
$30.76

Find 7% of $25 = (25/100) x 7 = 1.75, then add it to $25 because it's applied tax.

25 + 1.75 = $26.75

15% = split into 10 and 5 percent
10%= (26.75/10) = 2.675
5% = 1.3375, make sure you add this all in your working out.

2.675 + 1.3375 = 4.0125

4.0125 + 26.75 = 30.7625 then round it to two decimal places because it's money :)

malfutka [58]
Kilo means 1000 so 1 kiometer=1000 meter
so  every 1000 meter=1 kilometer
to convert,, just divide meters by 1000 and get km
2950/1000=2.95km
