8. Find the surface area of a triangular pyramid if the area of each phase is 16 cm² and each of its lateral faces has an area of 9 cm².
Answer:
The base of a right pyramid is an equilateral triangle with area 16√3 cm². area of one of its lateral faces is 30 cm²
To find : height (in cm) i
Solution:
The base of a right pyramid is an equilateral triangle with area 16√3 cm²
Area of an equilateral triangle = (√3 / 4) Side ²
(√3 / 4) Side ² = 16√3
=> Side ² = 64
=> Side = 8 cm
Distance of center of triangle to mid point of Side for Equilateral triangle = side/ 2√3 = 8/ 2√3 = 4/√3
Let say Height = H
Slant Height = √((4/√3)² + H²)
Area of lateral surface = (1/2) * base * Slat Height
= (1/2) * 8 * Slant height = 30
=> Slant height = 15/2
15/2 = √((4/√3)² + H²)
=> 225/4 = 16/3 + H²
=> 611/12 = H²
=> H = 7.135 cm

What is the solution set for -4x-10 ≤ 2?
Answer:
x≥−3
Step-by-step explanation:
Let's solve your inequality step-by-step.
−4x−10≤2
Step 1: Add 10 to both sides.
−4x−10+10≤2+10
−4x≤12
Step 2: Divide both sides by -4.
−4x /−4 ≤ 12 /−4
= x≥−3
brainliest please?Answer:
x ≥ -3
Step-by-step explanation:
you add 10 on both sides
-4x - 10 ≤ 2
+10 +10
= -4x ≤ 12
then you divide -4 on both sides to get the x by itself
12/-4 is -3
since you divided by a negative you flip the sign
The diameter of a bicycle wheel is 16 inches. How many revolutions will it take the wheel to travel about 192 inches?
a.8
b.4
c.1
d.16
Answer:
its actuly 12
Step-by-step explanation:
16x12=192
The number of revolutions it takes the wheel to travel about 192 inches is 4. Therefore, option B is the correct answer.
What is circumference of a circle?The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.
Given that, the diameter of a bicycle wheel is 16 inches.
We know that, the radius of a circle is diameter/2
Here, radius of bicycle wheel =16/2 =8 inches
As we know, the circumference of a circle is 2πr
Now, circumference of bicycle wheel is
2×3.14×8
= 50.24 feet
The wheel to travel about 192 inches
Number of revolutions =192/50.24
= 3.82
≈ 4
The number of revolutions are 4. Therefore, option B is the correct answer.

Area in square feet, of rectangle measuring 14 ft. 8 in. by 9 ft. 9 in.
Answer and Step-by-step explanation:
To find the area of a rectangle, you must multiple the length times the width.
14.8 × 9.9 = [tex]146.52 ft^2[/tex]
#teamtrees #PAW (Plant And Water)
Answer: 143 ft
Step-by-step explanation:
since the answer is supposed to be in square feet, convert the length/width/height to feet
14.6666....(irrational) ft x 9.75 = 143 ft
I could've used fractions but i'll be using decimals since they're easier to multiply together than mixed fractions
