Answer:

Therefore the true statement is that the height of the red prism is three times the height of the  blue prism.

Step-by-step explanation:

i) Volume of blue prism = (base of blue prism) \times (height of blue prism)

ii) base of red prism  = \frac{1}{3} \times (base of blue prism)

iii) Volume of red prism = (base of red prism) \times (height of red prism)

                  = \frac{1}{3} \times (base of blue prism) \times (height of red prism)

iv)  Volume of blue prism = Volume of red prism

   ∴  (base of blue prism) \times (height of blue prism) =  \frac{1}{3} \times (base of blue prism) \times (height of red prism)

∴height of blue prism =   \frac{1}{3} \times  (height of red prism)

Therefore the true statement is that the height of the red prism is three times the height of the  blue prism.

Answer:

Surface Area: 310 square inches.

Step-by-step explanation:

There are two ways to do this:

A) Formula for Surface Area of a Rectangular Prism = 2 * ( l*w + w*h + h*l). Where l is length, w is width & h is height. Based on the question:

l = 10 inch

w = 5 inch

h = 7 inch

Surface Area = 2 * ( 10*5 + 5*7 + 7*10) = 310 square inches.

B) Formula for Area of Rectangle = l*w, where l is length & w is width.

Look at the picture, I have marked the corners O,P,Q,R,S,T,U,V,W,X,Y,Z

If we calculate the Area of each rectangle and add them all we will get the surface area automatically.

  • Area of PQRS = 10*7 = 70 square inches
  • Area of STUV = 7*5 = 35 square inches
  • Area of VWXY = (7+5)*10 = 120 square inches
  • Area of ORYZ = 7*5 = 35 square inches
  • Area of RSVY = 10*5 = 50 square inches

Now add them all = 70+35+120+35+50 = 310 square inches.

the empire state building is 1250 feet tall. IF an object is thrown upward from the top of the building at an initial velocity o
ss7ja [257]

Answer:

Time for the object to get h(max)    s = 1.1875 sec

h (max)  = 1272.57 feet

Down time for the object to hit the ground   =  4.25 sec

Step-by-step explanation:

The relation

h(s)  =  -  16*s²  +  38* s  + 1250    (1)

Is equivalent to the equation for vertical shot

Δh = V(i)*t  -  1/2g*t²  (in this case we don´t have independent term since the shot is from ground level. We can see in (1), the independent term is 1250 feet ( the height of the empire state building), the starting point of the movement.

The description of the movement is:

V(s)  =  V(i)  - g*s     ⇒  V(s) = 38 - 32*s

At h(max)    V(s)  =  0      38/32  = s

So the maximum height is at  s = t = 1.1875 sec

The time for the object to pass for starting point is the same

t  =  1.1875 sec

h(max) is

h(max)  = - 16* (1.1875)² +  38 (1.1875) + 1250

h(max)  =  -  22,56  +  45.13  +  1250

h(max)  =  1272.57 feet

Time for the object to hit the ground is

h(s)  =  - 1250 feet

-1250  =  - 16 s² + 38*s  + 1250

-16s² +  38s  =  0

s ( -16s + 38 )  =  0

First solution for that second degree equation  is x = 0 which we dismiss

then  

( -16s + 38 )  =  0    ⇒ 16s   =  38     s  =  38/16

s =  2.375 sec    and  we have to add time between h (max) and to get to starting point  ( 1. 1875 sec)

total time is  = 2.375 + 1.875

Total time  =  4.25 sec

Whitepunk [10]
To answer this question you will use the formula for circumference of a circle to find how far around one revolution is.

C = pi x d
     3.14 x 32
C = 100.48 feet

Multiply the distance around one time by 4.3 to get the distance traveled in one revolution and then multiply it by 3 for the 3 minutes.

100.48 x 4.3 x 3 = 1296.19 feet
This is approximate and is closest to answer choice D.

3 plus 6 times the number of white marbles for a total of 15
Anton [14]
The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides:     6x = 12.
Isolate variable by dividing 6 on both sides:          x = 2
The number of white marbles is 2.
