The mean of six numbers is 25. Three of the numbers are 15, 15, and 30. The second unknown number is twice the first unknown num
svlad2 [7]

Answer:

The first unknown number is 10 the second is 20 and the third is 60

Step-by-step explanation

Since there is six numbers you have to multiply 25 times 6 = 150

Then 15+15+30=60

150-60= 90

10+20=30

30 times 2 equals 60

30+60=90

90+60= 150

150 divided by 6 = 25

zysi [14]
Well, the cereal cost 2.5, and the store is selling for 3.5, so is 1 buck more.

if we take 2.5 to be the 100%, what is 1 off of it in percentage?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
2.5&100\\
1&p
\end{array}\implies \cfrac{2.5}{1}=\cfrac{100}{p}\implies p=\cfrac{1\cdot 100}{2.5}\implies p=\stackrel{\%}{40}

" A car is travelling around a horizontal circular track with radius r = 230 m at a constant speed v = 17 m/s as shown. The angl
Luda [366]
R = 230 m
v = 17 m/s

Formula: |Ac| = v^2 / r

Point A

|Ac| = v^2 / r = (17m/s)^2 / (230m) = 1.257 m/s^2

Components:

cos(25) = - [ x-component / |Ac| ] => x-component = -|Ac|*cos(25)
sin(25)  = - [y-component / |Ac| ] => y-component = - |Ac|*sin(25)

x-component = - 1.256 * cos(25) m/s^2 = - 1.139 m/s^2
y-component =  -1.256 * sin (25) m/s^2 = - 0.531 m/s^2

Point B

|Ac| = 1.256

x-component = - 1.256 cos(58) = - 0.666 m/s^2
y-component = + 1.256 sin(58) = + 1.065 m/s^2

The radius of a cylindrical water tank is 4 ft, and its height is 6 ft, what is the volume of the tank?
Nataliya [291]

Answer:

96π cu ft.

Step-by-step explanation:

V = Bh      B = area of the base     h = height

The base is a circle, so B = \pi r^{2} = \pi 4^{2} = 16\pi

V = 16π(6) = 96π cu ft.
