Answer: I think it is 521 inches cubed
Step-by-step explanation:
First, I found the surface area of the shape on the bottom. Then I did the same thing for the shape on the top and added them together. But I noticed there was one side on the top shape that I had to subtract from the total. That is how I got 521. But I'm not sure.

A certain building has a triangular shaped face to link up of the sides of the triangular base or 145 feet 257 feet in 290 feet five find the area of the base of the building
Answer:
18617.66 ft^2
Step-by-step explanation:
sides of triangular base
a= 145ft ,
b = 257ft ,
c = 290ft
calculate the area of the base
The base is a scalene triangle hence the area is calculated as follows
s = ( a + b + c ) / 2
= ( 145 + 257 + 290 ) / 2 = 346
Area of triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}[/tex]
= 18617.66 ft^2
Help with number 8 please :)) <3
Answer:
A
Step-by-step explanation:
a = integer/whole number
Any whole number divided by 0 is 0.
0 is an integer/whole number.
What is the area of the base?
Answer:
24 in²
Step-by-step explanation:
Hello there!
the figure shown is a triangular prism
The base is the triangle
So we need to find the area of the triangle using this formula
[tex]A=\frac{bh}{2}[/tex]
where b = base and h = height
The base (triangle) has a base length of 8 inches and a height of 6 inches
Having found the information we needed, we plug it into the formula
So
[tex]A=\frac{6*8}{2} \\6*8=48\\\frac{48}{2} =24\\A=24in^2[/tex]
So the area of the base is 24 in²

Answer:
352 sq. inches
Step-by-step explanation:
32 x 22 = 704
704 / 2 = 352
Answer:
352 sq. inches
Step-by-step explanation:
The area of a triangle is found by the formula 1/2bh
aka 1/2 of base times height
the height is 22 and the base is 32 so we multiply 22 by 32
We get 704 but not the end we have to multiply that by 1/2 or divide by 2
Do that and you get 352
b=32 h=22
22*32=704
704/2 or 704*1/2 = 352
Hope I helped (p.s. brainliest?)

A shipping container is in the shape of a right rectangular prism with a length of 5 feet, a width of 12.5 feet, and a height of 14 feet. The container is completely filled with contents that weigh, on average, 0.78 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
102 pounds
Step-by-step explanation:
Volume of Right rectangular prism = 12 * 8.5 * 4 = 408 cubic feet
Density = Mass / Volume
=> 0.25 = Weight of contents in container / Volume of container
=> 0.25 = Weight of contents in container / 408
=> Weight of contents in container = 0.25 * 408
=> Weight of contents in container = 102 pounds
Answer:
683lb
Step-by-step explanation:
A formula for finding SA, the surface area of a rectangular prism, is
SA = 2(ab + ac + bc), where a, b, and c represent the lengths of the edges of the prism. What is the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches?
A.
B.
C.
D.
Step-by-step explanation:
SA=2*(12*6+12*4+6*4)
SA=2*(72+48+24)
SA=2*144
SA=288
Writing Linear Equations
Two less than five times a number x is equal to 13. Solve for x.
Answer:
x = 3
Step-by-step explanation:
5x - 2 = 13 (write the equation)
5x - 2 + 2 = 13 + 2 (isolate the variable)
5x = 15
5x/5 = 15/5 (simplify)
x = 3
Answer: x=3
Step-by-step explanation:
13=5x-2
13+2=5x
15=5x
x=15/5
x=3
Find the area of the shaded region.
Answer:
60+4.5pi
Step-by-step explanation:
6×10 obv + area of circle pi(r^2) and half that for a semi cirxle
Answer:
9 π^2
Step-by-step explanation:
Let's just fined the area of the rectangle: Area= 2lw = A=60
Now, we know the diameter of the Spehre which is 10 -2 -2 = 6, the radius is half of that = 3
A=πr2 = A≈28.27
add A≈28.27 + 60 = 88.27 = 9 π^2≈88.82643

Answer:
x = 7
Step-by-step explanation:
A triangle's total interior angle measurement will equal 180°.
Set all measurements equal to 180:
(82) + (9x - 6) + (6x - 1) = 180
Simplify. Combine like terms:
(82 - 6 - 1) + (9x + 6x) = 180
(82 - 7) + (15x) = 180
(75) + 15x = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, Subtract 75 from both sides of the equation:
15x + 75 = 180
15x + 75 (-75) = 180 (-75)
15x = 180 - 75
15x = 105
Next, divide 15 from both sides of the equation:
(15x)/15 = (105)/15
x = 105/15
x = 7
7 is your value for x.

Alex spent $126.42 on new school clothes and supplies. If $86.23 of that was spent on supplies, what percent of what she spent on supplies?
Answer:
68%
Step-by-step explanation:
To find the percentage we are going to put the amount she spent on supplies over the total amount she spent and multiply it by 100.
= 86.23 ÷ 126.42 × 100
= 68.2% or 68%

Step-by-step explanation:
Are these similar and what is the reason?
Answer:
yes
Step-by-step explanation:
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size.
The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
Step-by-step explanation:
so I will that they are similar
Max has $156. He spends 2/3 of his money on groceries. How much money did he have remaining? Explain.
Answer:
$52
Step-by-step explanation:
first 2/3*156 and you get 104
Then you do 156 -104 and you will have your answer
Answer:
Max has $52 remaining
Step-by-step explanation:
[tex]\frac{2}{3}*\frac{156}{1} = \frac{312}{3} \\[/tex]
simplify [tex]\frac{312}{3}[/tex] by 3 to get [tex]\frac{104}{1}[/tex]

For two functions, f(x) and g(x), a statement is made that f(x) = g(x) at
x = 5. What is definitely true about x = 5? (2 points)
Both f(x) and g(x) cross the x-axis at 5.
O Both f(x) and g(x) cross the y-axis at 5.
Both f(x) and g(x) have a maximum or minimum value at x = 5.
Both f(x) and g(x) have the same output value at x = 5.
Answer:
Both f(x) and g(x) have the same output value at x = 5
Step-by-step explanation:
When we are writing a function, while x gives the input value, writings like f(x), g(x) or h(x) will represent the output values of the input value of x
Now, looking at the relation, we are told that the value of f(x) = g(x) at x = 5
What this mean is that at x = 5; the output value of g(x) is the same as the output value of f(x)
Hence, we can conclude that both functions have the same output value at the given input value of x = 5
Answer:
D) Both f(x) and g(x) have the same output value at x = 5.

I got it right on the test.
