Find the surface area of the pyramid.
A. 64 in.2
B. 56 in.2
C. 88 in.2
D. 118 in.2
Answer:
I believe it may be A.
Step-by-step explanation:
The formula looks complicated so I'm going to simplify it.
SA = 1/2 (4 * side of base * height) + side of base^2
Using this, we can get our answer.
1/2 (4 * 4 * 6) + 4^2
1/2 * 96 + 16
48 + 16
64
Thus the answer should be 64in. ^2
The surface area of the pyramid is 64 inch².
What is Surface area?A three-dimensional shape's surface area is the sum of all of its faces. To calculate the surface area of a shape, we add the areas of each face.
Here the pyramid has 4 triangles and one square.
Side of base square = 4 inch
Height of Triangle = 6 inch
Then, area of base
= side²
= 4²
= 16 inch²
and, Area of Triangle = 1/2 x base x height
= 1/2 x 4 x 6
= 12 inch²
So, the Surface Area of pyramid
SA = 1/2 (4 x t) + side²
= 12 x 4 + 16
= 48+ 16
= 64 inch²

which function grows at the fastest rate for increasing values of x?
f(x)=4x2+9x
h(x)=2x
g(x)=18x
Answer with explanation:
The given functions in x are
1. f(x)=4 x² + 9 x
2. h(x)= 2 x
3. g(x)=18 x
To check whether the function is increasing or not , there are two ways
1. The graph of function is sloping Upwards.
2. For, two real x number ,that is if , a ≥ b, then , f(a) ≥ f(b).
All the three given function in x, are increasing because ,for increasing , x , value of function increases.
For Integral numbers,
⇒Function 1
f(x)=4 x² + 9 x
f(1)=4×1²+9×1
=4 +9
=13
f(2)=4×2²+9×2
=4 × 4 +18
=16 +18
= 34
f(2) - f(1)=34 - 13
= 21
→→Function B
h(x)= 2 x
h'(x)=2
Rate of change of function is constant, which is equal to 2.
→→Function C
g(x)=18 x
g'(x)=18
Rate of change of function is constant, which is equal to 18.
≡⇒→Rate of change of function ,f(x) is maximum among three functions.That is, f(x)=4 x² + 9 x , has highest rate of increasing, for increasing value of, x.

How many pieces 3/7 of a foot each can I make out of 7/2 feet of rope?
Final answer:
To find out how many 3/7 foot pieces can be made from 7/2 feet of rope, divide the total rope length by the length of one piece, resulting in 8 whole pieces with a small amount left over.
Explanation:
The question asks how many pieces of rope, each measuring 3/7 of a foot, can be made from a total length of 7/2 feet. To find the answer, you need to divide the total length of the rope (7/2 feet) by the length of each piece (3/7 foot), which is a division problem involving fractions:
(7/2) ÷ (3/7) = (7/2) × (7/3) = 49/6.
This means you can cut the rope into 49/6 pieces. Since you can't have a fraction of a physical piece of rope, the practical answer is that you can make 8 whole pieces of rope, each 3/7 of a foot long, with a little bit of rope left over.
You can make 8 full pieces of rope that are each 3/7 of a foot long from 7/2 feet of rope, with a small leftover piece.
Explanation:The question asks how many pieces of rope measuring 3/7 of a foot each can be made from 7/2 feet of rope. To find this, we divide the total length of rope by the length of one piece:
Total length of rope: 7/2 feet
Piece length: 3/7 foot
We divide 7/2 by 3/7, which is the same as multiplying 7/2 by the reciprocal
of 3/7 (which is 7/3):
(7/2) * (7/3) = 49/6
This simplifies to 8 1/6, which means you can make 8 full pieces of rope that are each 3/7 of a foot long, with a small piece leftover.

will is 23% taller than wanda so wills height is ___ % of wanda’s height
Since Wanda's height represents 100% and Will is 23% taller, then Will's height is 123% of Wanda's height.
Explanation:The question tells us that Will is 23% taller than Wanda. In terms of understanding this percentage in relation to Wanda's height, it helps to see Wanda's height as 100% because 100% represents a whole, in this case, Wanda's entire height. If Will is 23% taller, then his height is 100% of Wanda's plus an additional 23%. Thus, Will's height is 123% of Wanda's height.

Melanie’s bedroom walls are 45% painted. The area of her walls totals 420 square feet. What is the number of square feet of Melanie’s walls that still need to be painted?
The percentage of Melanie's walls that still needed to be painted is 55 % and the number of walls is 231 feet²
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage of Melanie's walls that still needed to be painted be A
Now , the equation will be
The total number of walls = 420 feet²
The percentage of Melanie's walls that are painted = 45 %
So , the remaining percentage A = 100 - percentage of Melanie's walls that are painted
The percentage of Melanie's walls that still needed to be painted A = 55 %
And , the number of walls that needed to be painted = percentage of Melanie's walls that still needed to be painted A x total number of walls
On simplifying , we get
The area of walls that needed to be painted = ( 55/100 ) x 420
The area of walls that needed to be painted = 231 feet²
Hence , the area of Melanie's wall to be painted is 231 feet²

a kitchen measures 3.75 meters by 4.2 meters, wha is tye area of the kitchen
Final answer:
The area of a kitchen measuring 3.75 meters by 4.2 meters is calculated by multiplying these dimensions, resulting in an area of 15.75 square meters.
Explanation:
The question asks for the area of a kitchen with dimensions 3.75 meters by 4.2 meters. To find the area of a rectangle, you multiply its length by its width. Therefore, the calculation for the area of the kitchen is as follows:
Area = Length × Width= 3.75 m × 4.2 m
= 15.75 square meters
Thus, the area of the kitchen is 15.75 square meters. This calculation is a basic application of geometry, specifically dealing with areas of rectangles.
Bill Gates wants to construct an in ground swimming pool for his dog. he wants it's length to be 8 yards shorter than twice it's width. he then wants to surround it with a concrete walkway 6 yards wide. he can only afford 570 square yards of concrete. what should the dimensions be of the pool ?
Please find the attached file for a better understanding of the solution provided here:
ABCD is the swimming pool and PQRS is the extent of the swimming pool plus the concrete walkway which is 6 yards wide.
Now, we know that the length is 8 yards shorter than twice it's width. Thus,
l=2w-8
Now the area of the region, A'B'QP will be: length x width. Now, the length here is l+6+6=2w-8+12=2w+4 and width is 6.
Thus, area of the region A'B'QP is (2w+4)x6=12w+24
Likewise, the area of the region D'C'RS will similarly be 12w+24 too.
Now, the area of the region BB'C'C will be 6 x w=6w
Similarly, the area of the region AA'D'D will be 6 x w=6w
Therefore, the total area of the walk way will be:
[tex] 2(12w+24)+2\times 6w=570 [/tex]
[tex] 24w+48+12w=570 [/tex]
[tex] 36w+48=570 [/tex]
[tex] \therefore w=14.5 [/tex]
Therefore, length, l will be:
[tex] l=2w-8=2\times 14.5-8=29-8=21 [/tex]
Therefore, the dimensions of the swimming pool are:
Length, l= 21 yards and Width, w=14.5 yards

factor ax^2−ay−bx^2+cy+by−cx^2
Final answer:
The expression ax²-ay-bx²+cy+by-cx² can be factored by first combining like terms to get (a-b-c)x² + (b+c)y - ay and then refactoring to x²(a-b-c) + y(b+c-a).
Explanation:
The student has given the expression ax²-ay-bx²+cy+by-cx² to factor. To factor this expression, we must first combine like terms and then group the terms in a way that allows us to factor by grouping.
Combining like terms gives us: (a-b-c)x² + (b+c)y - ay. We can then factor out common factors from each group. Notice that x² terms can be grouped together, as well as the y terms.
The refactored expression is x²(a-b-c) + y(b+c-a). Depending on the specific values of a, b, and c, further factoring may be possible, but with the given information, this is the factored form of the expression.
Final answer:
To factor the expression ax² - ay - bx² + cy + by - cx², group the terms based on their factors and factor out the common factors. The factored form of the expression is x²(a - b - c) - y(a - c + b).
Explanation:
To factor the expression ax² - ay - bx² + cy + by - cx², we can group the terms based on their factors. Group ax² - bx² - cx² together, and -ay + cy + by together. Factoring out the common factors from each group, we get:
x²a - b - c) - y(a - c + b)
Thus, the factored form of the expression is x²(a - b - c) - y(a - c + b).
