What is the value of the expression when s=2 and t=1.5 -3|5-s3|+3t

Elena-2011 [213]

Answer:

The value of the given expression is -4.5

Step-by-step explanation:

We need to find the value of the expression $-3|5-s^3|+3t$ when s=2 and t=1.5

Putting the values of s and t in the given expression.

So,

$-3|5-s^3|+3t=-3|5-(2)^3|+3\times 1.5\\\\=-3|5-8|+4.5\\\\=-3|-3|+4.5$

We know that, |-a|=a

So,

$=-3|-3|+4.5\\\\=-3(3)+4.5\\\\=-9+4.5\\\\=-4.5$

So, the value of the given expression is -4.5

-8 equals x + 11 / -2

slava [35]

If the equation is $-8=x+\frac{11}{-2}$ :

$-8=x+\frac{11}{-2}\\-8=x-\frac{11}{2}\\-8+\frac{11}{2}=x-\frac{11}{2}+\frac{11}{2}\\-\frac{16}{2}+\frac{11}{2}=x\\x=-\frac{5}{2}=-2\frac{1}{2}$

If the equation is $-8=\frac{x+11}{-2}$ :

$-8=\frac{x+11}{-2}\\-8(-2)=\frac{x+11}{-2}(-2)\\16=\frac{-2(x+11)}{-2}\\16=x+11\\16-11=x+11-11\\x=5$

Hopefully the math was self-explanatory. If it is not, please feel free to ask for a step-by-step, in depth explanation, and I will edit my answer to accommodate.

The volume of a cone-shaped funnel is 236 cubic centimeters. The radius of the funnel is 5 centimeters Find the height of the fu

DochEvi [55]

Answer:

9 cm

Step-by-step explanation:

V = 1/3 pi r^2 h

V = 1/3 * 3.14 * 5^2 * h

236 = 1/3 * 3.14 * 25 * h

236 = 26.1667 h

236 / 26.1667 = h

9.019 = h

Rounded to the nearest whole number the h is about 9 cm.
