To convert Hectometers to kilometers you divide by 10:

8.7 / 10 = 0.87 kilometer

8.7 hectometers = 87 kilometers = FALSE.

Multiply centigrams by 10 to get milligrams:

4.02 x 10 = 40.2

4.02 centigrams = 40.2 milligrams = TRUE.

Milliliter to liter:

Divide milliliters by 1000:

0.001 / 1000 = 0.000001

0.001 milliliter = 0.1 liter = FALSE.

Meter to kilometer:

Divide meters by 1000:

0.004 / 1000 = 0.000004

0.004 meter = 0.000004 kilometer = TRUE.

What is the approximate perimeter of the figure?

exis [7]

<span>This is a perimeter of 1/4 of a circle. We know that the radius of the circle: r = 5 in. Also the perimeter of the circle is : 2 * r * Pi = 2 * 5 * 3.14 = 31.4 in. For the quarter of a circle it its 31.4 : 4 = 7.85 in. After that we can add the 2 lengths of the radius: P = 5 + 5 + 7.85 = 17.85 in ( approx. 17.9 in ). Answer: C ) 17.9 in. </span>

If 10a+10b=35, what is the average (arithmetic mean) of a and b?

worty [1.4K]

Answer:

1.75

Step-by-step explanation:

If a and b are two numbers, then their arithmetic mean is

$\dfrac{a+b}{2}$

Given:

$10a+10b=35$

Divide this equation by 10:

$a+b=3.5$

Now, divide it by 2:

$\dfrac{a+b}{2}=\dfrac{3.5}{2}\\ \\\dfrac{a+b}{2}=1.75$

julsineya [31]

x= A ticket
y=b ticket
x+y=500
10x+60y=6000
-------------------
10x+60y=6000
- x+y=500 (*10) ---> 10x+10y=5000
-------------------
10x+60y=6000
- 10x+10y=5000
-------------------
50y=1000
y=1000/50
y=20
b ticket =20

x+y=500
x+20=500
x=500-20
x=480
a ticket=480
answer is the last option ,
