Answer:
37 yd²
Step-by-step explanation:
The computation of the surface area of this triangular pyramid is shown below:
The surface area of this triangular pyramid is
But before that
Lateral area = 3(1 ÷ 2) × base × height
= (3 ÷ 2)(4 yd)(5 yd)
= 30 yd²
Now
base area = 1 ÷ 2 × base × height
= 1 ÷ 2(4 yd)(3.5 yd)
= 7 yd²
Now the total surface area is
surface area = lateral area + base area
= 30 yd² + 7 yd²
= 37 yd²

rectangle in terms of its width,
x. Find the area of the rectangle
when its width is 9.5 units.
what is 4x – 97 + 12 – x = -80.5
Answer: x - 1.5
4x – 97 + 12 – x = -80.5
3 x - 85 = -80.5
3 x - 85 +85 = -80.5 + 85
3x = -80.5 + 85
3x = 4.5
x = 1.5
Step-by-step explanation: hope this helps
Answer:
x=1.5
Step-by-step explanation:
4x-97+12-x=-80.5
Combine like terms
-97+12=-85
4x-x=3x
now you have 3x-85=-80.5
add 85 to both sides and now you have
3x=4.5
Now divide 3 to both sides and you get x=1.5

Select all names that apply to the number. The length of the side of a square that has an area of 77 square yards.
A real
B whole
C rational
D irrational
E integer
The length of the side would be sqrt(77) = 8.7749.....
This can be classified as two answers:
A and D
This is a real number
It is also an irrational number because it can’t we written as a simple fraction.

the surface area of the rectangular prism is given by formula S=2 (ab+bh+ah) find the value of h when a = 10, b=6 and s=440
Answer:
10
Step-by-step explanation:
440=2(60+6x+10x)
220=60+16x
160=16x
x=10
h=10
The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.
We have been given data as:
a = 10, b = 6 and s = 440
The surface area of the rectangular prism is given by the formula
⇒ S = 2(ab + bh + ah)
Substitute the values of a = 10, b = 6 and s = 440 in the above formula
⇒ 440 = 2(60 + 6h + 10h)
⇒ 220 = 60 + 16h
⇒ 220 - 60 = 16h
⇒ 160 = 16h
⇒ 16h = 160
⇒ h = 160/16
⇒ h = 10
Therefore, the required value of h is 10.

Luis is making cookies. He needs 1 1/4 cup of sugar to make 12 cinnamon cookies and 1/2 cups of sugar to make 24 chocolate chip cookies. How many cups of sugar does he need to make both recipes?
Answer: 1 3/4 cups of sugar
Step-by-step explanation:
To make the first recipe, Luis needs 1 1/4 cup of sugar.
To make the second recipe, he needs 1/2 cup of sugar.
The number of cups of sugar that he need to make both recipes will be gotten by adding both cups of sugar together. This will be:
= 1 1/4 + 1/2
= 1 1/4 + 2/4
= 1 3/4
Therefore, 1 3/4 cups of sugar are needed

A student is evaluating the expression below for n=3.7.12.8+6(n-0.5) in what order should the student do the steps?
Answer:
32
Step-by-step explanation:
The given expression is :
12.8+6(n-0.5)
We need to evaluate the expression for n = 3.7
Put n = 3.7 in the above expression.
12.8+6(3.7-0.5)
= 12.8+6(3.2)
= 12.8 + 19.2
= 32
So, the value of the given expression is equal to 32.

Surface area of a rectangular prism form : A=2(wl+hl+hw)
Substitute in values from the question: 558=2[(9)(11)+h(11)+h(9)]
Multiply where applicable: 558=2[(99)+11h+9h]
Combine like terms: 558=2[(99)+20h]
Divide both sides by 2: 279=(99)+20h
*note- This step can also be seen as multiplying the right side by 2 without messing with the left at all (558=(198)+40h) then you would solve in the same fashion as I will from here just with the alternative numbering*
Subtract to isolate the h: 180=20h
Divide both sides to isolate the h: 9=h
Now we see that the missing dimension h=9in
*note- I did not bold the equations with squares so please don't be confused by that*

Substitute in values from the question: A=2π(3)(5)+2π[tex]3^{2}[/tex]
Multiply were applicable: A≈94.2+56.5
Add remaining values: A≈150.8
Now we see that the total surface area is 150.8[tex]m^{2}[/tex]
*note- whenever we solve for volume or SA of a figure we square the unit ([tex]m[/tex]➞[tex]m^{2}[/tex])*
6.
Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]
Substitute in values from the question: A=2π(6)(2)+2π[tex]6^{2}[/tex]
*note- we use 6 instead of the given value 12 because the equation calls for the radius and not the diameter*
Multiply were applicable: A≈75.2+226.2
Add remaining values: A≈301.6
Now we see that the total surface area is 301.6[tex]in^{2}[/tex]
*note- whenever we solve for volume or SA of a figure we square the unit ([tex]in[/tex]➞[tex]in^{2}[/tex])*

Answer:
9)
x^2 + 2x + 1 = (x + 1)^2
10)
x^2 - 6x + 9 = (x - 3)^2
Step-by-step explanation:
To complete the square, add the square of half of the x-term coefficient.
Then use the factoring of a perfect square trinomial.
a^2 + 2ab + b^2 = (a + b)^2
a^2 - 2ab + b^2 = (a - b)^2
9)
x^2 + 2x + 1 = (x + 1)^2
