1. Determine the lateral and total surface

(I need full explanation on how to solve
Answers
Answer:
Laterial surface area: 73 cm²Total surface area: 93 cm²Step-by-step explanation:
The laterial surface area is the sum of the areas of the triangles. There are two triangles with dimensions: base = 4 cm, height = 8cm and two triangles with dimensions: base = 5cm, height = 8.2cm.
The laterial surface area LSA is:
LSA = 2 • ( 4.8/2) + 2 • ( 5 • 8.2/2)
LSA = 4 • 8 + 5 • 8.2
LSA = 73 cm²
The total surface area SA is the LSA plus the area of the base of the pyramid, which is a rectangle with dimensions: 4cm x 5cm:
SA = LSA + 4 • 5
SA = 73 cm + 20 cm²
SA = 93 cm²

What is the volume of the composite figure?
Answers
Answer:
1428 in³
Step-by-step explanation:
To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism [tex](A=l*w*h)[/tex] and volume of a triangular prism.
[tex](A=\frac{1}{2} (b*h )[/tex]
If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:
17 × 8 × 5 = 680 in³.
Solving for the triangular prism gives us:
A = 1/2 (11 × 8 × 17)
A = 748.
Add these two volumes to find the volume of the composite figure:
748 + 680 = 1428 in³
Hope this helps!

A carpenter lays 18 square feet of tile in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?
Answers
Answer:
x=24
Step-by-step explanation:
there are different ways to solve the problem
set up a proportion:
16/(2/3)=x/1
cross multiply
(2/3)x=16
(3/2)(2/3)x=(3/2)(16)
x=24 square feet per hour
a carpenter lays 16 square feet in 40 minutes (2/3 of an hour)
this means he lays 4 square feet every 10 minutes
8 square feet in 20 minutes
12 square feet in 30 minutes
24 square feet in 60 minutes

What is the value of x? *
31°
53°
Answers
Answer:
X = 96
Step-by-step explanation:
This one is pretty simple
So we're dealing with angles here.
So what we want to do is add the two angles and it =180
Here's the equation so it makes more sense:
[tex]A+B=180[/tex]
so we'd place in those numbers
[tex]53+31=180[/tex]
add the two angles together
[tex]53+31=84[/tex]
than we'd subtract from 180 getting the value of X
[tex]180-84=96[/tex]
[tex]x=96[/tex]

Explain why dividing each side of \small 3x^2=6x by \small 3x is not a reliable way to solve the equation.
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]3x^2 = 6x[/tex]
Required
Why dividing by [tex]3x[/tex] is not reliable
The reason is that, the given expression is a quadratic equation and as such, it will most likely have two solutions.
So, when the expression is divided by [tex]3x[/tex], the solution will be [tex]x = 2[/tex], leaving out the other possible solution.
The right way is:
[tex]3x^2 = 6x[/tex]
Subtract 6x from both sides
[tex]3x^2 - 6x = 6x - 6x[/tex]
[tex]3x^2 - 6x = 0[/tex]
Factorize
[tex]3x(x - 2) = 0[/tex]
Split
[tex]3x = 0\ or\ x - 2 = 0[/tex]
Solve for x in both cases:
[tex]x = 0\ or\ x = 2[/tex]

...............................................................................................................................................
Answer:
The correct option is B.
Step-by-step explanation:
From the given table it is notices that the value of y decreases as x increases, therefore it is an inverse variation.
The inverse variation is defined as
Where, k is constant of proportionality.
From the given table it is clear that the value of y is 6 at x=2.
The value of k is 12. So, the required model is
Therefore, the correct option is B.

Answers
Answer:
2x + y = -2, x + 2y = 2
4x + y - 2z = 0, 2x+ 3z = 9 , -6x - 2y + z = 0
x + y = 4 , x - y = 2
Step-by-step explanation:
Answer:
x=2 and y=−5
Step-by-step explanation:
Let's solve your system by elimination.
7x−y=19;2x−3y=19
Multiply the first equation by -3,and multiply the second equation by 1.
−3(7x−y=19)
1(2x−3y=19)
Becomes:
−21x+3y=−57
2x−3y=19
Add these equations to eliminate y:
−19x=−38
Then solve−19x=−38for x:
−19x=−38
(Divide both sides by -19)
x=2
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
7x−y=19
Substitute2forxin7x−y=19:
(7)(2)−y=19
−y+14=19(Simplify both sides of the equation)
−y+14+−14=19+−14(Add -14 to both sides)
−y=5
y=-5

How to know if the side lengths can form a triangle:
Add together two of the lowest numbers. If it is greater than the largest number, it can form a triangle.
13. Yes, these side lengths can form a triangle.
-- 4 + 5 = 9.
-- 9 is greater than 7, the largest length.
14. No, these side lengths can't form a triangle.
-- 2 + 3 = 6
-- 6 is equal to 6, not greater than.
15. Yes, these side lengths can form a triangle.
-- 2 + 4 = 6
-- 6 is greater than 5, the largest number.
16. Yes, these side lengths can form a triangle.
-- Don't get confused when you see that there are two side lengths that are the same (it means that this is an isosceles triangle); the rules still apply.
-- 2 + 8 = 10
-- 10 is greater than 8, the largest number.
17. Yes, these side lengths can form a triangle.
-- 5 + 6 = 11
-- 11 is greater than 9, the largest number.
18. Yes, these side lengths can form a triangle.
-- 4 + 5 = 9
