Please help. I’m confused

Mathematics
1 answer:
Simora [160]3 years ago
6 0

Answer:

when x=6, y=30

when x=7.5, y=37.5

Step-by-step explanation:

Just plug in the value of x into the equation y=5x

so when x=6, the equation will be y=5(6).  In this case y=30

when x =7.5, the equation will be y=5(7.5). So y=37.5

What is 6 and 2/5 + 7 and 9/10? simplify answer
netineya [11]

Answer:

Step-by-step explanation:

What I would do is convert everything to have a denominator of 10 so it could be easier to add.

6 would equal 60/10

7 would equal 70/10

2/5 would equal 4/10

now add all together

60/10 + 70/10 + 4/10 +9/10 and you get 143/10. If you wanted to simplify you would get 14 3/10 or 14.30

Convert 0.0000.489 to scientific notation
Volgvan
I do not understand why there are two decimal places.
But either ways if you are asking for :
0.0000489 then it is 4.89*10⁻⁵
0.489 then it is 4.89*10⁻¹
The trick is to count the zeroes to the first actual significant number you see and then write the number you counted with a negative sign for your power. 
I hope this helps!

A central angle in a circle with a radius of 3 cm intercepts an arc with a length of 6 cm what is the measure of the central ang
Fiesta28 [93]

Answer:

114.59\°

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

In this problem we have

r=3\ cm

substitute

C=2\pi (3)=6 \pi\ cm

Remember that

360\° subtends the arc length of the complete circle

so

by proportion

Find the measure of the central angle for an arc length of 6\ cm

\frac{360}{6\pi } \frac{degrees}{cm} =\frac{x}{6} \frac{degrees}{cm} \\ \\x=6*360/(6\pi )\\\\ x=114.59\°
