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:

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.

Option 3 or Option 4.
Step-by-step explanation:
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!
A storage shed with a flat roof is 12 feet long by 9 feet wide by 4 1/2 feet tall.
How many cubic feet of storage space does the shed enclose?
Answer:
To get the volume of the shed in yards, multiply 4*3*2.5=30
since one cubic yard is equal to 27 cubic feets, multiply 27 with 30 to get the volume in cubic feets 27*30=810

Tim has read 30 % of a book. He has 56 more pages to finish. How many pages are there in the book?
Answer:
80 pagesStep-by-step explanation:
Let the number of pages is xTim has read 30 % of a bookRemaining
100% - 30% = 70%70% of x is 0.7x
0.7x = 56x = 56/0.7x = 80 pagesAnswer:
[tex] \bf \huge 80 \: pages[/tex]
Step-by-step explanation:
Given that :Tim has read 30 % of a book.He has 56 more pages to finish.to find :How many pages are there in the book ?let us assume :total pages of book is 100•/•explanation :⟼ total book = 100•/•
⟼ Tim has read 30 % of a book.
⟼ 100 - 30 •/• = 70 •/•
⟼ 70 •/• = 56 pages
⟼ 1 •/• = 56 / 70
⟼ 100 •/• = 56 / 70 × 100
⟼ 100 •/• = 56 / 7 × 10
⟼ 100 •/• = 8 × 10
⟼ 100 •/• = 80 pages
∴ tim has 80 total pages in book.

SOMEONE PLEASE HELP WITH SCALE FACTORS!!!! I will mark brainliest if right!!! Explain!
Answer:
68
Step-by-step explanation:
Find the scale Factor:
What do you do to 10 to make it 4?
Divide by 2.5 or Multiply by 0.4
Since, Scale factors are always written as multiplications, use x 0.4
Find the area of the smaller pentagon:
Value 1 x Scale Factor = Area of larger pentagon x 0.4 = 68.8 ≈ 68

Solve 3n – 4= 14
Put the steps in order to solve the equation from first to last.
n = 6
Add 4 to both sides
Divide both sides by 3.
Answer:
n = 6
Step-by-step explanation:
Given
3n - 4 = 14 ( add 4 to both sides )
3n = 18 ( divide both sides by 3 )
n = 6

Answer:
Step-by-step explanation:
Slope of line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Slope of the line passing through (-3, 0) and (0, 5) = [tex]\frac{5-0}{-3-0}[/tex]
= [tex]-\frac{5}{3}[/tex]
Line passing through a point (h, k) and slope 'm' will be,
y - h = m(x - k)
Since, line passing through (11, 0) is parallel to the line given in the graph,
Slope of the parallel line will be same as [tex]-\frac{5}{3}[/tex]
Equation of a line passing through (11, 0) and slope = [tex]-\frac{5}{3}[/tex]
y - 0 = [tex]-\frac{5}{3}(x-11)[/tex]
y = [tex]-\frac{5}{3}(x-11)[/tex]
Now satisfy this equation with the points given in the options,
Option (1)
For (1.67, -15.59),
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, given point doesn't lie on the line.
Option (2)
For (-0.33, -13.59)
-13.59 = [tex]-\frac{5}{3}(-0.33-11)[/tex]
-13.59 = -18.88
False
Option (3)
For (0.67, -18.59),
-18.59 = [tex]-\frac{5}{3}(0.67-11)[/tex]
-18.59 = 17.22
False
Option (4)
For (1.67, -15.59)
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, none of the points given in the options are lying on the line.
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.

approximate the solutions to this system.
y = 3x2 + x − 6
y = x − 4
Round your answers to the nearest hundredth.
Answer:
[tex] \displaystyle ( x_{1},y_{1}) = (0.82, - 3.18) \\ ( x_{2},y_{2}) = ( - 0.82, - 4.82)[/tex]
Step-by-step explanation:
we are given a system of quadratic and linear equation
we want to figure out x and y
in other words the coordinates where the linear function intercept quadrilateral function
to do so
you can use substitution method
since y equals to both equation so substitute:
[tex] \displaystyle {3x}^{2} + x - 6 = x - 4[/tex]
move right hand side expression to left hand side and change its sign so there's only 0 left on the left hand side:
[tex] \displaystyle {3x}^{2} + x - 6 - x + 4= 0[/tex]
simplify addition:
[tex] \displaystyle {3x}^{2} -2=0[/tex]
add 2 to both sides:
[tex] \displaystyle {3x}^{2} = 2[/tex]
divide both sides by 3
[tex] \displaystyle \frac{ {3x}^{2} }{3} = \frac{2}{3} [/tex]
[tex] \displaystyle {x}^{2} = \frac{2}{3} [/tex]
square root both sides:
[tex] \displaystyle {x} = \sqrt{\frac{2}{3} } \\ x = \frac{ \sqrt{2} }{ \sqrt{3} } [/tex]
rationalise the denominator by multiplying √3/√3:
[tex] \displaystyle x = \pm\frac{ \sqrt{6} }{3} = \pm0.82[/tex]
now let's figure out y
substitute the value of x to the linear equation:
[tex]y = \pm0.82 - 4[/tex]
when positive
[tex]y = - 3.18[/tex]
when negative
[tex]y = - 4.82[/tex]
Answer:
(x1,y1) = (0.82, - 3.18)
(x2,y2) = (-0.82, -4.82)
