How do you find the height of a 3d object such as a triangle or a cylinder

Answers

Answer 1

Answer: In the case of a cylinder, one or several of the following data must be provided: the total area/lateral area and the circumference/area of the base or the area of the base and the volume. Ex: provided the circumference of the base = 10π inches, and the lateral area = 50π inches², the equation can be written as 50π ÷ 10π = 5 inches.

Answer 2

Answer: Well, for ANY prism (included cylinder), divide volume by area of base.
h = V / B

For ANY pyramid (included cone), divide volume by area of base, then multiply it by 3.
h = 3V / B

A grocery store so the six pack of bottled water for $3.79 a 12 pack for $6.89 which package cost The least per bottle explain your reasoning

Answers

Easiest way to find out the answer to this is to find out the price of every water bottle. To do that you have to divide the whole value by the amount of water bottles. (3.79/6 & 6.89/12) The first one should equal something around .63 each and the second should be around .57. Technically the second pack is cheaper than the other by around .6 cents.

a giraffe can run 46.93 feet per second how many feet can it run in 1.8 seconds with out cross multiplying justify your awnser

Answers

46.93 x 1.8 = 84 .474 feet in 1.8 seconds
the multiplier is 1.8 as it is a 80% increase on the 1 second that we already have the information for

If the giraffe can run 46.93 in one second it can run 46.93*1.8=84.474 feet in 1.8 seconds.

Based on the type of equations in the system, what is the greatest possible number of solutions (x2+y2=9/9x+2y=16? A=1
B= 2
C= 3
D= 4

Answers

Answer:

`Option B.

Step-by-step explanation:

The given system of equations is

$x^2+y^2=9$

$9x+2y=16$

The graph of first equation is circle and the graph of second equation is a line.

We know that a line can intersect a circle at most 2 times. So, the greatest possible number of solutions is 2.

First equation can be rewritten as

$x^2+y^2=3^2$

It is the standard form of a circle $(x-h)^2+(y-k)^2=r^2$ , where (h,k) is center and r is radius.

In the above equation h=0,k=0 and r=3. It is a circle with radius 3 and centered at origin.

The second equation is

$9x+2y=16$

It is a linear equation.

Table of values.

1 3.5

2 -1

Plot these points on a coordinate plane and connect them by a straight line.

From the below graph it is clear that the line and circle intersect each other at two points. So, the given system of equation have two solutions.

Therefore, the correct option is B.

Jan,Mya, and sara ran a total of 64 miles last week. Jan and Mya ran the same number of miles. Sarah ran 8 less miles than Maya. How many miles did Sarah run?

Answers

Jan, Maya and Sarah run a total of 64 miles per week
How many miles did Sarah run if she ran less than 8 miles compare to Maya and Jan
Jan and Maya = x
Sarah = x
Total miles = 64

=> 64 = x + x + x-8
=> 64 = 3x – 8
=> 72 = 3x
=> x = 24
Since Jan and Maya ran the same miles, they ran 24 miles each
Since Sarah is 8 less than Maya’s and Jan’s ran each
=> x – 8
=> 24 -8
=> 16
Sarah ran 16 miles in a week.
