A solid has faces that consist of two squares and four congruent rectangles. What type of solid is it?

lozanna [386]

A solid that has faces which consist of two squares and four congruent rectangles is called a rectangular prism. It has six faces that are rectangles. It has the same cross-section along a length, which makes it a prism. It is also a "cuboid". Hope this answers the question.

Nathan has a sculpture in the shape of a pyramid. The height of the sculpture is 3 centimeters less than the side length, x, of

uysha [10]

Let
x-----------> the side length of a pyramid square base
h-----------> the height of the sculpture in the shape of a pyramid

we know that
h=(x-3)
Volume=162 cm³
Volume=x² *(x-3)/3
then
x² *(x-3)/3=162----------> x³-3x²=486----------> x³-3x²-486=0
x³-3x²-486=0-------- this equation can be used to find the length of the sculpture’s base

using a graph tool-----------> to find the solution
x=9 cm -------------> see the attached figure
h=(x-3)-----> h=9-3--------> h=6 cm

the answer is
the length of the sculpture’s base is 9 cm
the height of the sculpture is 6 cm

Answer: B) Infinitely many solutions; both equations are equivalent

==============================================================

Work Shown:

x+y = 4 ... start with the first equation

x + (-x+4) = 4 ... replace y with (-x+4)

x-x+4 = 4

0x+4 = 4

0+4 = 4

4 = 4 ... this is a true statement regardless of what x you pick

So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.

Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.

The resting heart rate of an adult is usually about 60 beats per minute. Use your completed table to find approximately how many

Fofino [41]

if 60 beats = 1 minute, and a minute is 60 seconds then 1,000,000 beats has to be divided by 60 = 16667 rounded to the nearest hundred thousand and divide that by 1440 (How many seconds in a day) = 11.574 days.

That equates to 11days, 13hours, 46 min, and 40 sec
