Enter the formula to find the surface area of a prism involving area of the Base and Perimeter of the base
Answer:
p=3+4+5=12
Step-by-step explanation:
Answer:
96 inches2 or 352 cm2
Step-by-step explanation:
-Okay so, we know that The lateral surface area of a prism is the sum of the areas of its lateral faces. And The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Then Usually, if "right" or "oblique" is not mentioned, you can assume the prism is a right prism. The general formula for the lateral surface area of a right prism is L.S.A.=ph where p represents the perimeter of the base and h represents the height of the prism.
n/15=21/35 Solve for the missing value in the proportion.
Answer:
n=9
Step-by-step explanation:
21/35 has a gcf of 7. so reduce to 3/5
move 3/5 to the left side to get
n/15=-3/5=0
solve as a linear equation.
n/15=-3/5=0 is equivalent to .67*n-0.6=0
which is equal to n=-9

the width of a rectangle measures (8c-5)(8c−5) centimeters, and its length measures (2c 10)(2c 10) centimeters. which expression represents the perimeter, in centimeters, of the rectangle?
The expression that represents the perimeter of the rectangle is [tex]$\boxed{20c + 10}$[/tex] centimeters.
We are given that;
Width= (8c-5)(8c−5) centimeters
Length= (2c 10)(2c 10) centimeters
Now,
The perimeter of a rectangle is given by the formula:
P = 2l + 2w
where l is the length and w is the width.
[tex]$w = (8c-5)\ cm$[/tex]
and
[tex]$l = (2c+10)\ cm$[/tex]
Substituting these values into the formula for the perimeter, we get:
[tex]$P = 2l + 2w = 2(2c+10) + 2(8c-5) = 4c + 20 + 16c - 10 = \boxed{20c + 10}\ cm$[/tex]
Therefore, by rectangle the answer will be [tex]$\boxed{20c + 10}$[/tex].

Find the selling price of a suit if a store
paid $140 for it, and it was marked up 80%
over the cost.
Answer:
$252
Step-by-step explanation:
The store paid $140 for the suit. Let's first find the 80% of $140.
$140 x 80% = $112
So now we just need to add $112 to $140.
$140 + $112 = $252
A system of equations and its solution are given below. System A Complete the sentences to explain what steps were followed to obtain the system of equations below. System B To get system B, the equation in system A was replaced by the sum of that equation and times the equation. The solution to system B the same as the solution to system A.
Answer:
To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.
Step-by-step explanation:
A system of equations and it’s solution are given below.
System A.
x-y=3
-2x+4y=-2
Solution: (5,2)
Complete the sentences to explain what steps were followed to option the system of equations below.
System B
x-y=3
2x=10
To get to system B the (first/second) equation in system A was replaced by the sum of that equation and the (first/second) equation multiplied by (4....2.....-3) . The solution to system B (is/ is not) the same as the solution to system A.
Solution:
To get system B:
First write the first equation in system A. x - y = 3
Multiply the second equation in system A by 4 and add to the first equation in system A to get:
2x = 10
x = 10/2 = 5
Put x = 5 in x - y = 3
5 - y = 3
y = 5 - 3 =2
The solution to system B is the sam as that of system A
To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.

vegetable ghee is stored in the cylindrical vessel of internal radius 1.4m height 1.5m. if it is transferred into the rectangular tin cans 33cm * 10cm*5cm how many cans are required to empty the vessel
Answer:
5,598 cans are required to empty the vessel
Step-by-step explanation:
The volume of a cylinder of radius r and height h is:
[tex]V = \pi r^2h[/tex]
The volume of a box of dimensions X, Y, and Z is:
V=X.Y.Z
A cylinder of r=1.4 m and height h=1.5 is used to store vegetable ghee. It contains a volume of:
[tex]V_1 = \pi 1.4^2*1.5[/tex]
[tex]V_1=9.236\ m^3[/tex]
Converting to cubic cm:
[tex]V_1=9.236*1,000,000\ cm^3[/tex]
[tex]V_1=9,236,282\ cm^3[/tex]
The volume of each rectangular tin can is:
[tex]V_2=33*10*5=1,650\ cm^3[/tex]
[tex]V_2=1,650\ cm^3[/tex]
The number of cans required to empty the vessel is:
[tex]V_1/V_2=9,236,282/1,650 = 5,598[/tex]
5,598 cans are required to empty the vessel
the coordinates of 3 points are a(-1, -6), b(3, -12) and c(k, 6). Find the value of k if a, b and c are collinear.
Plz answer quickly and step by step.
Answer:
The value of [tex]k[/tex] is -9.
Step-by-step explanation:
If [tex]A(x,y) = (-1,-6)[/tex], [tex]B(x,y) =(3, -12)[/tex] and [tex]C(x,y) = (k,6)[/tex], then [tex]\overrightarrow{BC} = \alpha\cdot \overrightarrow{BA}[/tex]. By vectors sum, we find each vector below:
[tex]\overrightarrow{BA} = A(x,y)-B(x,y)[/tex] (1)
[tex]\overrightarrow{BA} = (-1,-6)-(3,-12)[/tex]
[tex]\overrightarrow{BA} = (-4, 6)[/tex]
[tex]\overrightarrow{BC} = C(x,y)-B(x,y)[/tex] (2)
[tex]\overrightarrow{BC} = (k,6)-(3,-12)[/tex]
[tex]\overrightarrow{BC} = (k-3, 18)[/tex]
By substituting in the equation defined at the begining of this answer:
[tex](k-3, 18) =\alpha\cdot (-4, 6)[/tex]
[tex](k-3, 18) = (-4\cdot \alpha, 6\cdot \alpha)[/tex] (3)
The value of [tex]\alpha[/tex] is:
[tex]6\cdot \alpha = 18[/tex] (3a)
[tex]\alpha = 3[/tex]
If we know that [tex]\alpha = 3[/tex], then the value of [tex]k[/tex] is:
[tex]k-3 = -4\cdot \alpha[/tex]
[tex]k = 3-4\cdot \alpha[/tex]
[tex]k = 3-4\cdot (3)[/tex]
[tex]k = 3-12[/tex]
[tex]k = -9[/tex]
Then, the value of [tex]k[/tex] is -9.

16 and what other number is the geometric mean of 32
Answer:
16 and 64
Step-by-step explanation:
The geometric mean n of two numbers a and b can be given as;
√ab = n
In this question;
a = 16
b = ?
n = 32
So we have
16 * b = 32^2
b = 32^2/16
b = (32 * 32)/16
b = 2 * 32
b = 64

[Right Triangles Only] sin∅ = opposite over hypotenuse [Right Triangles Only] cos∅ = adjacent over hypotenuseStep-by-step explanation:
Step 1: Define
We are given a right triangle. We can use trig to solve for the missing side length.
Step 2: Set up ratios
We can choose between the 2 angles and have multiple ratios to solve for x.
sin33° = x/51
cos57° = x/51
Hence, we see that the 1st option would be the correct answer.
