Answer:
1.2
Step-by-step explanation:
0.12 looks like the correct answer but its not because if you look at the problem its 0.2 and 0.12 is smaller than 0.2 so its 1.2 because 0.2 x 6 = 1.2

Square pyramid A and square pyramid B are similar. Their respective heights are 6 and 15 inches. The volume of pyramid B is 312.5 cubic inches. What is the volume of pyramid A?
The volume of pyramid A is 20 cubic inches.
Given that:
Height of pyramid of A and B are 6 and 15 inches, respectively.
Since square pyramid A and square pyramid B are similar, their corresponding sides are proportional.
Let the volume of pyramid A be V and the scale factor between the two pyramids be k.
The volume of a pyramid is given by V = (1/3) × base area × height.
Since the base of pyramid B is k times the base of pyramid A, and the height of pyramid B is also k times the height of pyramid A, we can set up the following relationship:
V(B) = k³ × V(A)
Given that the height of pyramid A is 6 inches and the height of pyramid B is 15 inches, we can calculate the scale factor k as follows:
k = height of B / height of A = 15 / 6 = 2.5
Now, we know the scale factor k, and we are given the volume of pyramid B as 312.5 cubic inches. We can find the volume of pyramid A:
V(B) = k³ × V(A)
312.5 = 2.5³ × V(A)
312.5 = 15.625 × V(A)
Now, solve for V(A):
V(A) = 312.5 / 15.625
V(A) = 20
The volume of pyramid A is 20 cubic inches.

Solve for x (5x +40) A. AB. BC, AC B. BC. AC. AB C. AC. AB. BC (7x+8) (10x) с A D. BC. AB. AC Which of the following lists the sides in order from shortest to longest?
Answer:
D
Step-by-step explanation:
The shortest side is the side opposite the smallest angle, the longest side is opposite the largest angle.
First find the measure of the angles in the triangle.
The sum of the 3 angles = 180° then
5x + 40 + 10x + 7x + 8 = 180
22x + 48 = 180 ( subtract 48 from both sides )
22x = 132 ( divide both sides by 22 )
x = 6
Then
∠ A = 7x + 8 = 7(6) + 8 = 42 + 8 = 50°
∠ B = 5x + 40 = 5(6) + 40 = 30 + 40 = 70°
∠ C = 10x = 10(6) = 60°
The shortest side is opposite ∠ A , that is BC
The longest side is opposite ∠ B , that is AC
The sides in order from shortest to longest are
BC, AB, AC → D

Plz help me the question is what is the volume of the prism in cubic centimeters
Answer:
120 cubic cm
Step-by-step explanation:
The Volume of a Triangular Prism = [tex]1/2Bh[/tex], where B = height x length of triangle, divided by 2 (because that's how we find the area of a triangle).
So the height of the triangle is 4 cm, and the length is 6 cm; 6 x 4 = 24, divided by 2 is = 12 cm.
Then the other H, the height of the triangular prism, is = 10 cm, and 12 x 10 is equal to 120 cm ^3.

In the given triangle value of [tex]x= 73.4[/tex] units and [tex]y= 46.2[/tex] units ( round to nearest tenth)
What is triangle?" Triangle is defined as the two dimensional geometrical shape with three vertices, three sides and three angles enclosed in it."
Formula used
Pythagoras theorem
(Hypotenuse)² = (adjacent side)² + (perpendicular side)²
[tex]tan\theta = \frac{perpendicular side}{adjacent side}[/tex]
According to the question,
In the given triangle,
Hypotenuse [tex]= x[/tex]
Perpendicular side [tex]= y[/tex]
Adjacent side [tex]= 57[/tex]
Value of [tex]\theta = 39[/tex]
Substitute the value of the given triangle in the formula to get the missing values,
[tex]tan 39\°= \frac{y}{57} \\\\\implies 0.8098 = \frac{y}{57}\\\\\implies y = 57 \times 0.8098\\\\\implies y = 46.1586[/tex]
[tex]\implies y= 46.2[/tex] units (round to nearest tenth)
Substitute the value in the Pythagoras theorem we get,
[tex]x^{2} = (46.2)^{2} +(57)^{2} \\\\\implies x^{2} = 2134.44 + 3249\\\\\implies x = \sqrt{5383.44} \\\\\implies x = 73.37[/tex]
[tex]\implies x = 73.4[/tex] units (round to nearest tenth)
Hence, In the given triangle value of [tex]x= 73.4[/tex] units and [tex]y= 46.2[/tex] units ( round to nearest tenth)
