Find the surface area of
the prism.
12 in.
6 in.
5 in.
The surface area is in.2.
Answer:
324
Step-by-step explanation:
SA = 2 ( lw + hl + hw )
l = length
w = width
h = height
Given Dimensions
l = 6
w = 5
h = 12
* plug in to SA formula *
SA = 2 ( (6)(5) + (12)(6) + (12)(5) )
(6)(5) = 30
(12)(6) = 72
(12)(5) = 60
SA = 2 ( 30 + 72 + 60 )
30 + 72 + 60 = 162
SA = 2(162) = 324
For which segment is B a midpoint?
Answer:
AC with endpoints at A(1; -1) and C(5; 3)
PR and SU are parallel lines.
Which angles are alternate interior angles?
Answer:
Alternate interior angles are on opposite sides of the transversal, and between the parallel lines
Step-by-step explanation:
If you know two corresponding sides of two triangles and you know that the corresponding angles are equal, how can you find out if they are similar triangles?
a.
the other angles are proportional
c.
ratios of the sides will be equal
b.
the vertical angles will be congruent
d.
ratio of the sides will not be equal
Please select the best answer from the choices provided
A
B
C
D
Answer:
The answer is A) the other angles are proportional.
Explanation:
If you already know what 2 of the 3 sides are of each triangle, it only makes sense that the 3rd side would be proportional to those of the 1st triangle.
If pi is rounded to a whole number, what is a reasonable estimate for the circumference of a circle with a diameter of 18 cm?
57 cm
50 cm
54 cm
56 cm
Answer:
54 cm
Step-by-step explanation:
Hi there!
1) Round pi
π = 3.14159265...
Rounded to a whole number ⇒ 3
2) Determine the circumference
C = πd where d is the diameter
Plug in the diameter
C = 18π
Plug in π
C = 18(3)
C = 54
Therefore, a reasonable estimate for the circumference of this circle would be 54 cm.

In the diagram below. De and Ef are tangent to 0. Which equation could be solved to find y, the measure of DGF? O A. ;(-127) = 53 OB. }(v + 127) = 53 O c. }(y-53) = 127 OD. } (x + 53) = 127
Answer:
A
Step-by-step explanation:
The tangent- tangent angle DEF is half the difference of the measure of the intercepted arcs , that is
[tex]\frac{1}{2}[/tex] (y - 127) = 53 → A
The intercepted arcs of y is 1/2(y -127) = 53.
What is intercepted arc?
The intercepted arc exists the arc that exists inside the inscribed angle and whose endpoints exist on the angle. The vertex of an inscribed angle can be anywhere on the circle as stretched as its sides intersect the circle to construct an intercepted arc.
Let, DE and EF exist as tangents to O.
The value of y will be evaluated as follows:
For angle created outside of circle by intersection:
Two tangents or two secants or a tangent and a secant, the formula for angle created outside will be:
An angle formed outside = 1/2(Difference of Intercepted Arcs)
An angle formed outside exists ∠DEF = 53°
Intercepted arcs exist y and 127°
Hence, 53 = 1/2(y -127)
Therefore, the correct answer is option C). 1/2(y -127) = 53.

A. exponential
B. quadratic
C. cubic
D. linear
Answer:
Step-by-step explanation:
This is exponential. I'll show you how I found it. After many attempts at other types of functions, I realized the points were either forming a quadratic or an exponential. Definitely not a line.
the standard form of an exponential function is
[tex]y=a(b)^x[/tex] so we sub in coordinates from the table to determine what the equation is and then test it on another set of points to see if it works. Using the first coordinate of (1, 2):
[tex]2=a(b)^1[/tex] so
[tex]a=\frac{2}{b}[/tex] . The next coordinate is (2, 4), so:
[tex]4=\frac{2}{b}(b)^2[/tex] which simplifies down to
4 = 2b so
b = 2. Now we plug in 2 for b and solve for a:
a = 2/2 which is 1. So the equation, if this is exponential, is
[tex]y=1(2)^x[/tex] Let's test the next point in line and see if it works, (3, 8):
[tex]8?=?1(2)^3[/tex] and yes, 8 is equal to 2 cubed. And the next point says that 16 should equal 2 to the 4th, and it does, as well. So this is exponential...growth to be specific.

Find h.
9 ft
h = [?] ft
Answer:
[tex]\sqrt{77}[/tex] ft
Step-by-step explanation:
Hi there!
Notice how we can create a right triangle in the cone, where the base is 2 ft (4/2=2), the height is h and the hypotenuse is 9 ft.
Using these values, we can solve for h with the Pythagorean theorem: [tex]a^2+b^2=c^2[/tex] where a and b are the two legs of a right triangle and c is the hypotenuse.
Plug in 2 and h as a and b and 9 as c:
[tex]2^2+h^2=9^2\\4+h^2=81\\h^2=81-4\\h^2=77\\h=\sqrt{77}[/tex]

Is the triangle a right-angled triangle?
You must show your working.
Answer:
Yes, It is a Right Triangle.
Step-by-step explanation:
The hypotenuse is the longest side of the triangle, so for this problem we set the hypotenuse's value to 18.2
From there it doesn't matter which side is which, as both will undergo the same operations.
If the following equation is true, then it is a right triangle.
7²+16.8²= 18.2²
49 + 282.24 = 331.24
The equation is True.
It is a right-angled Triangle.

Which of the following statements describes the process for solving 4x ≥ -24?
A. Divide both sides of the inequality by 4 and flip the symbol.
B. Divide both sides of the inequality by -24 but don't flip the symbol.
C. Divide both sides of the inequality by 4 but don't flip the symbol.
D. Divide both sides of the inequality by -24 and flip the symbol.
Answer:
C. Divide both sides of the inequality by 4 but don't flip the symbol.
Step-by-step explanation:
When you solve an inequality, you have to get the x by itself. So, in this inequality, the first thing you would do is divide both sides of the inequality by 4. The new and solved equation would look like this:
x ≥ -6
Because multiplying by a negative, dividing by a negative, or having negatives on both sides of the inequality was not involved in solving for x, flipping the symbol is not needed.

Answer:
Given : isosceles right triangle hypotenuse = 8 cm
To find : leg of isosceles right triangle
Solution
isosceles right triangle
Hence Perpendicular = base
Both legs are of Equal length
Applying Pythagoras theorem
Perpendicular² + base² = Hypotenuse²
Hypotenuse = 8 cm given
=> Perpendicular² + base² = 8²
Perpendicular = base = x
=> x² + x² = 64
=> 2x² = 64
=> x² = 32
=> x = 4√2
legs of isosceles right triangle whose hypotenuse is 8 cm
are 4√2 cm
