A sculptor is planning to make two triangular prisms out of steel. The sculptor will use △ABC for the bases of one prism and △DEF for the bases of the other prism.
(a)Is △ABC similar to △DEF? Explain.
(b)Suppose the sculptor makes both prisms with the same height. Which prism will have a greater volume? How many times greater? SHOW YOUR WORK FOR BRAINLIEST!!
Answer:
a)
Verify is the corresponding sides have same ratio:
AB / DE = 50/60 = 5/6 BC / EF = 20/24 = 5/6Since the ratios are same, the triangles are similar
b)
If one dimension is same, the base areas will make difference by the square of the scale factor:
(6/5)² = 1.44 timesTwo numbers have a sum of - 6 and a product of 9.
Use the quadratic equation n^2 - 6n + 9 = 0 to determine the two numbers.
n2 - 6n + 9 = 0
Answer:
3, 3
Step-by-step explanation:
[tex]n^2 - 6n + 9 = 0 \\ n^2 - 3n - 3n+ 9 = 0 \\ n(n - 3) - 3(n - 3) = 0 \\ (n - 3)(n - 3) = 0 \\ n - 3 = 0, \: \: n - 3 = 0 \\ n = 3, \: \: n = 3[/tex]
Thus, the two numbers are 3, 3

An equilateral triangle has an altitude length of 33 feet. Determine the length of a side of the triangle.
Answer:
38.11 feet
Step-by-step explanation:
all three corners of an equilateral triangle are 60°
sin 60° = 33/x
0.8660 =33/x
x = 38.11 feet
Relation between the side and the altitude of the equilateral triangle can be given as,
[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]
The length of the side of the equilateral triangle is 38.105 feet.
What is equilateral triangle?When all the three sides and all the three angle of a triangle are equal, then the triangle is known as Equilateral triangle.
Relation between the side and the altitude of the equilateral triangle can be given as,
[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]
Here, [tex]a[/tex] is the side of the equilateral triangle and h is the altitude of the equilateral triangle
Given information-
Altitude of the equilateral triangle is 33 feet.
Put the value of altitude in above formula to find the length of the side of the equilateral triangle. Thus,
[tex]a=\dfrac{2}{\sqrt{3} } \times33\\a=38.105[/tex]
Thus the length of the side of the equilateral triangle is 38.105 feet.

Erik states that the two cones below have the same volume because of Cavalieri’s principle. 2 cones are shown. The first cone has a radius of r, a slant length of c, and a height of b. The second cone has a radius of r, a height of a, and a slant length of b. Is Erik’s statement correct? Why or why not? Yes, the solids are both cones and appear to have the same volumes. Yes, the area of the bases and the heights of the cones are the same, so the volumes are equal. No, the heights of the cones are not the same, so Cavalieri’s principle does not apply.
Answer:
D. No, the heights of the cones are not the same, so Cavalieri’s principle does not apply.

Of 570 people, 365 were male and 368 had brown hair. Of those with brown hair, 108 were female. What is the probability that a person was male or had brown hair? Write your answer as a reduced fraction.
Answer:
473/570
Step-by-step explanation:
No. of male = 365
No. of female = 570-365 = 205
No. of male with brown hair = 260
No. of female with brown hair = 108
the probability that a person was male or had brown hair = 365/570+108/570 = 473/570 [ for or case we add probabilities]
Answer:
Around 83% 473/ 570
Step-by-step explanation:
365 males + 108 females with brown hair = 473
Divide the number of outcomes desired by the total number of outcomes 473/570 = 0.829824....... = 82.98.....%

Answer:
-6
Step-by-step explanation:
g(-4) here x = -4
So, we have to take g(x) = x - 2
g(-4) = -4 -2 = - 6
g(1) , here x = 1 ,
So, we have to take g(a)= -x +1
g(-1) = -1 + 1 = 0
g(-4) + g(-1) = -6 +0 = -6

The correct option is,
⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Bella want to know what the students at her school think of her show. which is the BEST group to survey to find this information
Now, For getting accurate results she must select a random sample without bias
For this option a will not serve since she selects only students she recognizes.
Hence, Option B may not be right, as during show on the face they may not give correct opinion
And, Option C is right as a random sample is taken
And, Option D is wrong as the first 30 students may not be at random.
Thus, The correct option is,
⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.

I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.
On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.
In case you only can answer with one, I'll say is option 3, hope it helps!
