Each side of the square base is 5 inches long and the height of the pyramid is 5 inches. Approximately how much wood is in the pyramid?
Answer: [tex]41.67\ in.^3[/tex]
Step-by-step explanation:
Given
The side of the square base is 5 inches
height of the pyramid is 5 inches
The volume of a square pyramid is
[tex]V=\dfrac{1}{3}a^2h[/tex]
Putting the values
[tex]\Rightarrow V=\dfrac{1}{3}\times 5^2\times 5\\\\\Rightarrow V=41.67\ in.^3[/tex]
The pyramid contains [tex]41.67\ in.^3[/tex] of wood
please help me i really need it geometry?
Answer:
height= 30 area= 2160
Step-by-step explanation:
I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)
Then, to find area the formula is a=b*h
You already have the base in the image and you already calculated the height
Again, I don't know if this is right. It's not the same as how I do it here
Answer:
h = 15, A = 540
Step-by-step explanation:
Since the 2 legs are congruent then h is a perpendicular bisector, dividing the triangle into 2 right triangles.
Using Pythagoras' identity on one of the right triangles
with leg 72 ÷ 2 = 36 and hypotenuse = 39
h² + 36² = 39²
h² + 1296 = 1521 ( subtract 1296 from both sides )
h² = 225 ( take square root of both sides )
h = [tex]\sqrt{225}[/tex] = 15
Then
A = [tex]\frac{1}{2}[/tex] × 72 × 15 = 36 × 15 = 540 mi²
Find the selling price for each item given the cost and
the percent of markup or discount.
36. tennis shoes: $85; 24% discount
Answer:
$64.60
Step-by-step explanation: I believe this is right if not sorry. The first step is to multiply $85 by .24 and that is $20.40. Then take $20.40 from $85 (85-20.40) which is $64.60
What property of operations can be used to justify that the two expressions in this equation are equivalent? 6x^2 +4x=4x + 6x^2
Answer:
Commutative
Step-by-step explanation:
There are four basic property of operations to solve an algebraic expressions. They are associative, commutative, distributive and identity.
The expression given is : [tex]$6x^2 + 4x=4x+6x^2$[/tex]
So the given algebraic expression is a commutative property of operations. The commutative property states that when any two numbers are added in an expression the sum of the numbers are the same regardless of the order of the numbers that are added.
Thus the sum of the above expression will be same in which ever order the numbers are added.
Regan has been saving her allowance for months, and she finally has enough to buy a new flat-screen TV! The TV's screen is shaped like a rectangle that is 50 inches wide. The screen's area is 1,500 square inches.
Answer:
The length of the tv is 30 inches
Step-by-step explanation:
area is LxW, so 50 x L = 1,500
L = 1,500/50
L = 30

How do you decide where to shade an inequality whose boundary does not go through the origin?
Answer:
If it does not satisfy the inequality, shade the region which does not contain that point. All the points in the shaded region will satisfy the inequality. Note: The origin (0, 0) is usually the easiest point to test, provided it is not on the line.
Inequalities are used to represent unequal expressions.
The region to shade are the region that satisfy the inequality.
Take for instance the following inequality
[tex]\mathbf{y \ge 2x + 5}[/tex]
The above inequality represents greater than or equal to.
This means that, the regions that satisfy the inequality are the region on the line of [tex]\mathbf{y \ge 2x + 5}[/tex] and the areas above it.
If the inequality is less than, then the region below the line of the inequality will be shaded.

The volume of clay sculpture is 540 cubic inches.What is the volume of similar sculpture that is smaller by a scale factor of 1/2.
Answer:
67.5 in³
Step-by-step explanation:
Given that :
Volume 1 = 540 in³
Volume 2 of similar shape = x ; if the scale factor = 1/2
Volume of a shape = length * width * height)
The scale factor = 1/2
Volumetric factor = 1/2 * 1/2 * 1/2 = 1/8
Hence, the volume of similar sculpture will be :
540 in³ * 1/8 = 67.5 in³

Step-by-step explanation:
i kinda dont know what your asking but i tried
The common prime factor of the numbers 77 and 242? will be 11.
What is a prime factor?A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,
Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,
77 / 11 = 7
242 / 11 = 22
Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.

How would you do this maths question?
Answer:
Step-by-step explanation:
First you take the 142+B=180
because those 2 are supplementary
B=38
and you see the 2 lines on the 2 sides that means those two sides are equal to each other and the angles corresponding with them are also equal to each other.
and a triangle= 180 degrees
A and E are the same so A=E
180-B(38)= 142
and because A=E you do 142/2= 71
and now that you have A and E you don't need A or B for the last part so
E+(x)=180 because those two angles are supplementary.
and E is 71 so...
71+(x)=180 ---------180-71=x
X=109
