What is the formula for prism
Answers
Answer:
The formula for the volume of a triangular prism is:
V=(l)(w)(h)
Where l is the length of the triangle, w is the width of the triangle, and h is the height of the prism
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

1. Bill wants to buy coffee for his class at the LePhooPhoo Coffee Shop. He needs to buy 30 cups of coffee. The large coffees cost $4 and the medium coffees cost $3. If he spends $102 on coffee, how many of each size coffee did he buy?
Answers
Answer:
large = 12
medium = 18
Step-by-step explanation:
L + M = 30 => L = 30-M
4L+3M =102
substitute : L with M
=> 4(30-M)+3M =102
120-4M+3M = 102
- M = 102-120
-M = -18
=========> M = 18, L = 12

Answer:
80.5π cm
Step-by-step explanation:
We want to find the area where the label should go onto the can. If we were to take the label and flatten it onto a 2D surface, we would multiply 11.5 cm by the width, which is equivalent to the circumference of the circle. The circumference of the circle can be calculated using the equation 2πr. The radius is 3.5 cm, so the circumference of the circle is 7π. We multiply 7π by 11.5 to get 80.5π cm.

Between 06 00 and 10 00,the same day ,the volume of water in a reservoir decreased from 24 000L to 18 000L.What was the average rate of decrease in volume of water, giving your answer in L/h?
Answers
Answer:
-1.5 L/h
Step-by-step explanation:
The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.
We need to find the average rate of decrease in volume of water. It can be solved as follows :
[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]
The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

Find the height of a cylinder when the surface area is 1004.80 cm squared and the radius is 10 cm.
Answers
Step-by-step explanation:
[tex]volume =\pi {r}^{2}h[/tex]
[tex]area = \pi {r}^{2} [/tex]
CALCULATIONremember
[tex]\pi = 22 \div 7[/tex]
So, we will just place the area and equate it to the unknown volume including the height
1004.80 = 22/7 × 10× 10 × h
1004.80 = 314.26h
h = 3.197
2. A(an) ______________of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Answers
Answer:
A(an) altitude of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Step-by-step explanation:
AN ALTITUDE - An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.
Hence , the answer is an altitude .

what is the value of x? i need the work for it as well thank you so much!
Answers
Answer:
x=19
Step-by-step explanation:
okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.
6x+4=118
subtract 4 from both sides
6x=114
divide by 6 on both sides
x=19

allen= y=3/2+2 billy= y= 3/2+4
Step-by-step explanation:
ok both of the equation are (almost) the same except for the y intercepts.
y=mx+b... you are learning about that hopefully!
so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.
if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.
as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross because billy's line is higher then allens, billy's tree will always be higher

Answer:
8) 10 15/16 ft³
9) 20 5/6 ft³
Step-by-step explanation:
Volume of a rectangular prism is
l * b * h,
Question 8
We're given the area
Area = l * b
So we substitute the area for length and breadth.
Volume = Area * height
Volume = 4 3/8 * 2 1/2
Volume = 35/8 * 5/2
Volume = 175/16
Volume = 10 15/16 ft³
Question 9
Volume = 5 * 1 2/3 * 2 1/2
Volume = 5 * 5/3 * 5/2
Volume = 5 * 25/6
Volume = 125/6
Volume = 20 5/6 ft³
