Nadya [2.5K]2 years ago
3 0

Answer:

6.4

Step-by-step explanation:

To find the distance you have to do this formula.

\sqrt{(x2 -x1)^{2}+(y2-y1)^{2}}  \\\sqrt{(-2 -3)^{2} + (8-4)^{2}\\} \\\sqrt{(-5)^{2} + (4)^{2}} \\\sqrt{25 + 16} \\\sqrt{41} \\ \\\sqrt{41} = 6.40312\\6.4

6.4 is the answer rounded to the nearest tenth.

Hope this helps!!

If you have 5 tenths of a dollar, how much money do you have
horrorfan [7]
A tenth is 1/10.
5 tenths is 5/10.

5/10 is a fraction that can be made simpler, by dividing by 5, so that the fraction becomes 1/2.

1/2 is a half, so if you have a half a dollar, you have 50 cents.

Hope I helped. :)

A right cylinder has a base area of 16pi square inches and a height of 8 inches. which shape has the same volume as the right cy
Studentka2010 [4]

Answer:

64π^2  cubic inches

Step-by-step explanation:

The question is not complete, the shapes are not given

Diameter of base= 16π

Radius of base= 8π

Height of cylinder = 8 inches

Let us find the volume of the cylinder

V= πr^2h

V= π* (8π)* 8

V= 64π^2  cubic inches

Hence the volume of the cylinder is 64π^2  cubic inches

I need the base and hight
iris [78.8K]

Answer:

Height = 5 and Base = 10

Step-by-step explanation:

The base of the parallelogram is twice the perpendicular height of the parallelogram. The area of the parallelogram is 50 cm².

Formula for area of parallelogram = base × height

Base = 2h

Height = h

∴ Area = 2h × h = 50

Solution:

2h × h = 50

2h² = 50

\frac{2h^{2} }{2} = \frac{50}{2}

h² = 25

\sqrt{h^{2} } = \sqrt{25}

h = 5

∴ height = 5 and base = 2(5) = 10

Need help on this please
Jobisdone [24]

Answer:

157.08m²

Step-by-step explanation:

Since the area of a circle is A=πr²

The radius is 10, so

A=π10²

A=314.16 (rounded to nearest hundredth)

Half of that is 157.08.
