Two triangular prisms are similar. The perimeter of each face of one prism is double the perimeter of the corresponding face of the other prism. How are the surface areas of the figures related? The surface areas are the same. The surface area of the larger prism is 2 times the surface area of the smaller prism. The surface area of the larger prism is 4 times the surface area of the smaller prism. The surface area of the larger prism is 8 times the surface area of the smaller prism.
we know that
if the perimeter of each face of one prism is double the perimeter of the corresponding face of the other prism and the two triangular prisms are similar
then
the scale factor is equal to
so
substitute the value of the scale factor
therefore
the answer is the option
Answer:
The surface area of the larger prism is 4 times the surface area of the smaller prism.
Two sides of a parallelogram are 9.5 feet and 4.9 feet. The measure of the angle between these sides is 96°. Find the area of the parallelogram to the nearest 10th of a square foot
Answer:
The area of the parallelogram is of 46.3 square feet.
Step-by-step explanation:
Area of a parallelogram:
The area of a parallelogram, given two sides a and b and the angle C between them, is given by:
[tex]A = ab\sin{C}[/tex]
In this question:
[tex]a = 9.5, b = 4.9, C = 96º[/tex]
Sides in feet, so area in square feet.
Area
[tex]A = ab\sin{C} = 9.5*4.9\sin{96º} = 46.3[/tex]
The area of the parallelogram is of 46.3 square feet.

Find the area of the circle. Round your answer the nearest whole number, if necessary.
area: about
in.2
Answer:
Area = 314 in.²
Step-by-step explanation:
Radius of the circle = 10 in.
Formula for area of a circle = πr²
Radius (r) = 10 in.
Plug in the value of r into the formula
Area = π*10²
Area = π*100
Area = 314.159
Area = 314 in.² (nearest whole number)
Answer:
The area of circle is 314 in².
Step-by-step explanation:
Given :
Radius of circle = 10 in.To Find :
Area of circleUsing Formula :
[tex]\star{\small{\underline{\boxed{\sf{\red{Area_{(Circle)} = \pi{r}^{2}}}}}}}[/tex]

d. /pi/4
Please select the best answer from the choices provided
Answer:
c. /pi/2
Step-by-step explanation:
[tex]y = \sin(4x) \\ y = 2\pi \omega[/tex]
Option C , pi/2 is the period of the sine function y = sin (4x)
What is Amplitude ?The amplitude of a periodic variable is a measure of its change in a single period.
The amplitude of a non-periodic signal is its magnitude compared with a reference value.
sin4x=sin(4x+4h)
sin(θ+2π)=sinθ , we have 4h=2π , h=π/2
or it can be also understood as
The amplitude and period of y = a sin (bx + c ) are a and 2π/b
Here, a = 1 and b = 4.
This sine wave oscillates between the crests at y = 1 and the lowest points at y= -1 periodically, with period π/2 for one full wave.
period of sin(4x) is (1/4)x(period of sin(x))
= (1/4)x(2pi)
= (pi/2) .

Three postal workers can sort a stack of mail 10 minutes , 35 minutes, and 70 minutes respectively. find how long it takes them to sort the mail if all three work together
9514 1404 393
Answer:
7 minutes
Step-by-step explanation:
The total of stacks per minute is ...
1/10 +1/35 +1/70 = (7+2+1)/70 = 1/7 . . . . stacks per minute
The rate in minutes per stack is the reciprocal of this.
Working together, the workers can sort a stack of mail in 7 minutes.

Which values of x and y make triangle CDE = triangle HFG?
Answer:
Option (4)
Step-by-step explanation:
By the property of congruence of the triangles given in the figure,
ΔCDE ≅ ΔHFG
By applying triangle sum theorem in ΔCDE,
m∠C + m∠D + m∠E = 180°
32° + 112° + m∠E = 180°
m∠E = 180° - 144°
m∠E = 36°
Corresponding side and angles of two congruent triangles are equal in measure.
Therefore, m∠E = m∠G
36° = (4y + 8)°
4y = 36 - 8
4y = 28
y = 7
Similarly, FG = DE
41 = 3x + 2
3x = 41 - 2
3x = 39
x = 13
Therefore, Option (4) will be the correct option.

Answer:
x=13
y=32
Step-by-step explanation:
x+y=45
x+19=y
45-y+19=y
2y=64
y=32
x=13
Answer: The other number is 19 more than that number represented by x + 19
Equation: x + (x + 19) = 45
The numbers are 13 and 32
Step-by-step explanation:
So we know that the sum is 45, and that one of the numbers in the equation is 19 more than the other. We can call one of the numbers "x". The instructions tell us that the second number is 19 more than x, so the second number can be written as this equation: x+19
Equation: x + (x + 19) = 45
2x + 19 = 45
2x = 26
x = 13
Plug x back into the equation to find the second number (x + 19)
x + 19
13 + 19 = 32
help with the Triangle sum theorem
Answer:
180
Step-by-step explanation:
If you add 60 +60 + 60, or 60 + 50 + 70, both would add up to 180, since x = 60. This is why both triangles, have a complete of 180.
Answer:
A triangle has 3 sides in every triangle all the three sides should sum up to 180°.
In the 1st figure,
70+50+x=180 (being sum of triangle)
now 120+x=180
x=180-120
=60
Step-by-step explanation:
In the 2nd figure
x is 60
60+60+60=180,

Question for 1 B)
Answer:
x = 117
Step-by-step explanation:
Given
11 - [tex]\sqrt{x+4}[/tex] = 0 ( subtract 11 from both sides )
- [tex]\sqrt{x+4}[/tex] = - 11 ( square both sides )
(- [tex]\sqrt{x+4}[/tex] )² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117

find the measure of each angle indicated
a. 33
b. 36
c. 31
d. 136
Answer:
31
Step-by-step explanation:
Let the missing angle be x.
Sum of angles in a triangle is supplementary,
x + 20 + 129 = 180
x + 149 = 180
x = 180 - 149
x = 31
Answer:
31
Step-by-step explanation:
A triangle is 180 degrees.
129 + 20 = 149
180 - 49 = 33
Finished goods inventory is $197,000. If overhead applied to these goods is $72,000, and the overhead rate is 150% of direct labor, how much direct materials cost was incurred in producing the inventory
Answer:
77,000
Step-by-step explanation:
If 72,000 is 150% of direct labor, then direct labor is 48,000 (72000/1.5)
direct labor 48000
overhead. 72000
total. 120,000
total costs: 197,000
less total above: 120,000
=material costs. 77,000
