Total surface area of tringular prism
10 cm
6 cm
4 cm
8 cm
Answer:
144 cm^2
Step-by-step explanation:
The formula for a triangle is (L x W)/2. We plug this in so our first two sides are 24 and 24 square centimeters. The top side is 10 x 4, or 40 cm. The bottom side is 8 x 4, or 32 cm. The back side is 6 x 4, or 24 cm.
24 + 24 + 40 + 32 + 24 = 144 square cm
Answer:= 144cm²
Step-by-step explanation: 4x8 =32
4x6= 24
4x10= 40
8x6=48
add 32+24+40+48 =144cm²

Answer:
A. 200
B. Growth
C. 118%
Step-by-step explanation:
Answer:
Initial population size=200
The function represents a growth
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 200(1.18)^t
To find initial population size we will take t = 0
P(0) = 200(1.18)^0
= 200(1)
= 200
To find that function represent growth or decay
P(1) = 200(1.18)^1
= 200(1.18)
= 236
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(236 - 200 / 200) * 100%
= 235%

Solve the linear equation 29 - 3x = 5x + 5
Answer:
x = 3
Step-by-step explanation:
29 - 3x = 5x + 5
You want to have the variable of x on one side of the equation, so add 3x to both sides.
29 = 8x + 5
You want to isolate the variable of x, so subtract 5 from both sides.
24 = 8x
You want the variable x on its own, so divide both sides by 8.
3 = x
Check your answer by plugging x back into the original equation.
29 - 3(3) = 5(3) + 5
Solve.
29 - 9 = 15 + 5

Answer:
x = 14
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{DF}{AC}[/tex] = [tex]\frac{EF}{BC}[/tex] , substitute values
[tex]\frac{x}{21}[/tex] = [tex]\frac{18}{27}[/tex] ( cross- multiply )
27x = 378 ( divide both sides by 27 )
x = 14

There is a building, if you are observing from the outside it looks like a parallelogram with one of the interior angles as 108. What will be the exterior angle that can be used for parking?
Answer:
Exterior angle to be used for parking is 72°
Step-by-step explanation:
I've attached an image of a paralelogram.
Now, we are told that from the outside it looks like a parallelogram with one of the interior angles as 108.
This means that the bigger angle internally would be 108°
Which from the attached image is angle B internally or angle D internally.
So, the interior angle observed will be either at point B or D on the parallelogram.
Now, the sum of angles on a straight line is 180°
Thus,
Internal angle D + External Angle D = 180
Or
Internal angle B + External Angle B = 180
Internal angle is 108°
Thus;
External angle for either B or D = 180 - 108 = 72°
So the exterior angle to be used for parking is 72°

the total surface area of a hemisphere is 45
[tex]\pi\p[/tex]
CM square find its volume
Answer:
The volume of the hemisphere
V = 121.33086 cubic centimeter
Step-by-step explanation:
Step(i):-
Given that the total surface area of a hemisphere = 45π cm²
The total surface area of a hemisphere = 3π r²
Equating
3π r² = 45π
[tex]r^{2} = \frac{45}{3} =15[/tex]
r = [tex]\sqrt{15} = 3.87[/tex]
The radius of the sphere 'r' = 3.87
Step(ii):-
The volume of the hemisphere
[tex]V = \frac{2}{3} \pi r^{3}[/tex]
[tex]V = \frac{2}{3} \pi (3.87)^{3}[/tex]
we know that π = 3.14
[tex]V = \frac{2}{3} (3.14) (3.87)^{3}[/tex]
V = 121.33086 cubic centimeter

A 254-foot tall radio tower is located partway between a building and a tree. The angle of elevation from the base of the building to the top of the tower is 36°, and the angle of elevation from the base of the tree to the top of the tower is 62°.
Answer: here's your answer
485 ft
Step-by-step explanation:
step 1
Find the distance from the base of the building to the base of the radio tower
Let
x -----> the distance from the base of the building to the base of the radio
we know that
tan(36°)=254/x
x=254/tan(36°)=349.60 ft
step 2
Find the distance from the base of the tree to the base of the radio tower
Let
x -----> the distance from the base of the tree to the base of the radio tower
we know that
tan(62°)=254/x
x=254/tan(62°)=135.05 ft
step 3
Find the distance from the base of the building to the base of the tree
Adds the distances
349.60 ft+135.05 ft=484.65 ft
Round to the nearest foot
484.65 ft=485 ft
