the base of a right prism is an equilateral triangle each of whose sides measures 4cm.the altitude of the prism measures 5cm.Fin
o-na [289]

Answer:

V=34.64\ cm^3

Step-by-step explanation:

Given that,

The side of an equilateral prism = 4 cm

The altitude of the prism = 5 cm

We need to find the volume of the prism. The formula for the volume of a prism is as follows :

V=A\times h

Where

A is the area of equilateral triangle, A=\dfrac{\sqrt3}{4}a^2

So,

V=\dfrac{\sqrt3}{4}a^2\times h\\\\V=\dfrac{\sqrt3}{4}\times 4^2\times 5\\\\V=34.64\ cm^3

So, the volume of the prism is equal to 34.64\ cm^3.

Hie, here's my question: $1800 at 6.5% for 30 months
miv72 [106K]

Answer:

A. 10105.86 (compound) or 3510 (simple)

B.11905.86 (compound) or 5310 (simple)

Step-by-step explanation:

If its's compound interest:

1800(1 +  \frac{6.5}{100}) ^{30} = 11905.86

11905.86 - 1800 = 10105.86

If it's simple interest:

6.5 \times 30 = 195

\frac{1800 \times 195}{100}  = 3510

3510 + 1800 = 5310

Which is the equation of a line that has a slope of -2/3 and passes through point (–3, –1)?
emmainna [20.7K]

Answer:

y = (-2/3)x-3

Step-by-step explanation:

Hello:

equation is the line is : y = ax+b        a is a slope

y = (-2/3)x+b

passing through the point (−3;−1) :   -1 =(-2/3)(-3)+b    so : b = -3

y = (-2/3)x-3

second solution : you can verify (-3 ; -1) in the equation : y = (-2/3)x-3
