Is anyone able to help me with finding the volume of the triangular prism
Answer:
1296 m³
Step-by-step explanation:
Volume = area * height.
Take any of the given faces. I have taken 12m & 12 m.
Area of this face = 1/2 * 12m * 12m
= 72 m²
Height = 18 m.
Thus,
Volume = 72m² * 18m = 1296 m³

Ricky is inviting 8 friends to a party. If each friend will get 6 cookies and in each box are 10 cookies, how many boxes will Ricky need to get?
Answer:
5
Step-by-step explanation:
8 times 6 is 48. 5 boxes times 10 in each one is 50 cookies.
Number of boxes Ricky needs to get to a party is equals to 5 boxes.
What is word problem?
" A word problem is a mathematical problem in which we represents the real life examples with the help of mathematical operation."
According to the question,
Number of friends invited in a party = 8
Number of cookies given to each friend = 6
Total number of cookies required for 8 friends = 8 × 6
= 48 cookies
Number of cookies in each box = 10 cookies
Number of boxes for 1 cookie = 1 / 10
Number of boxes for 48 cookies = (1 / 10) × 48
= 4.8
= 5 boxes (Number of boxes cannot be
in decimals)
Hence, number of boxes Ricky needs to get to a party is equals to 5 boxes.

(5, -8) m = -3
Write an equation in point-slope form
Answer:
y + 8 = - 3(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (5 - 8) , thus
y - (- 8) = - 3(x - 5) , that is
y + 8 = - 3(x - 5)

I need help with my question
the function f(x)=5(2)x represents number of bacteria, f(x), growing in a culture after x hours. How many bacteria are in the culture after 3 hours?
=============================================
Explanation:
Assuming the function is f(x) = 5(2)^x, then we replace every x with 3. Then we use the order of operations PEMDAS to simplify. Or we can use a calculator to simplify in one step.
f(x) = 5(2)^x
f(3) = 5(2)^3
f(3) = 5(8)
f(3) = 40

Mensuration
Suppose you want to put a boundary around your garden or field. For that, you need to find out the length of the boundary. Also, what if you want to find out the area and volume of different geometrical shapes. So this is something we are going to see in his chapter. So let us study the topic mensuration and mensuration formulas in detail.
Cylinder
Circles
Polygons
Rectangles and Squares
Trapezium, Parallelogram and Rhombus
Area and Perimeter
Cube and Cuboid
Question. Explain the use of mensuration in daily life?
Answer. The uses of mensuration in real life are many. Some of these uses are as follows:
Measurement of agricultural fields, and site areas for the purpose of purchase/selling transactions.
Measurement of volumes for packaging solid food items, milk, and liquids.
Measurements of surface areas for the purpose of estimating the painting of houses etc.
Question. What is meant by mensuration?
Answer. Mensuration refers to the branch of mathematics which involves the study of various geometrical shapes. Furthermore, it deals with the areas and Volume of such geometrical figures. So, this subject is all about the process of measurement.

of her favorite mechanical pencils. Estimate ABOUT how much did she spend?
Answer:
$14.20
Step-by-step explanation;
Rounding$6.24=$6.20
$1.95=$2.00
$5.59=$6.00
So now we have done our rounding, We just have to add them together now.
($6.20+$2.00+$6.00=$14.20)
Answer:
Mindy spent around $13
Step-by-step explanation:
I just added up all the whole numbers.
But I noticed that it is ALMOST $2 for a notebook.
So, even though the sum of all the whole numbers is 12, I assumed it would be more than 12.
So Mindy spent around $13
