How do i find surface area of a triangler prisim
Answer:
A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.
Hope it helps..

Amy owns 3 1/3 acres of farmland. She grows beets on 1/6 of the land. On how many acres
of land does Amy grow beets?
Plz
Answer:
5/9 acres
Step-by-step explanation:
3 1/3 areas is 10/3
1/6 of the land is covered with beets
[tex]\frac{10}{3} * \frac{1}{6} =\frac{10}{18}[/tex]
[tex]\frac{10}{18}[/tex] will simplify to [tex]\frac{5}{9}[/tex]
Hence the answer is 5/9 acres
A tablecloth is 82 inches long. What is the length in feet and inches?
Answer: 6 feet and 10 inches
Step-by-step explanation:
Each foot has 12 inches in it
You can either divide 82 by 12 or
1 foot: 12 inches
2 foot: 24 inches
3 foot: 36 inches
4 foot: 48 inches
5 foot: 60 inches
6 foot: 72 inches
7 foot: 84 inches
Since 7 foot is too much you can now take 6 feet (72 inches) and subtract it from 82
82-72=10
10 meaning 10 inches
6 feet and 10 inches
You may also divide but you will get a decimal like this:
6.83333333
Unit conversion is a way of converting some common units into another without changing their real value. The length of the table cloth is 6 ft 10 inches.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
In terms of measurement, one foot is 12 inches.
1 ft = 12 inches
Given that the table cloth is 82 inches long. Therefore, the length in feet and inches are,
Length = 82 inches
= 82 / 12 foot
= 6 10/12 foot
= 6 ft 10 inches
Hence, the length of the table cloth is 6 ft 10 inches.

calculate the diameter of the circle
Answer:
2.64cm
Step-by-step explanation:
A = π r^2
5.5 = π r^2
1.75 = r^2
r = 1.32
Diameter is then 2(1.32) = 2.64
Answer:
2.65 cm to the nearest hundredth
Step-by-step explanation:
A = πr^2 = 5.5
r^2 = 5.5/ π = 1.5707
r = 1.3231
Diameter = 2 * r

Answer:
I hope I didn't make mistakes, because I solved it without calculator
Step-by-step explanation:
[tex] \frac{5}{3} s + \frac{19}{15} = - \frac{3}{5} \\ \frac{5}{3} s = - \frac{3}{5} - \frac{19}{15} \\ \frac{5}{3} s = \frac{ - 9 - 19}{15} \\ \frac{5}{3} s = \frac{ - 28}{15} \\ s = - \frac{28}{15} \times \frac{3}{5} [/tex]

145°
Angle CDE is twice the size of angle DEF.
E
Work out the size of angle CDE.
You must show all your working.
160°
F
Total marks: 5
Answer:
since the sum of interior angles of hexagon is 720 °
you add the known angles
ie 115 +90+145+160
you get 510
subtract it from 720
you get 210
divide 210 by 3
you get 70
angle cde is 140
Answer:
∠ CDE = 140°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
let ∠ DEF be x then ∠ CDE = 2x
sum the interior angles and equate to 720
160 + 90 + 145 + 115 + 2x + x = 720 , that is
510 + 3x = 720 ( subtract 510 from both sides )
3x = 210 ( divide both sides by 3 )
x = 70
Then
∠ CDE = 2x = 2 × 70 = 140°

In triangle ABC, the length of side AB is 10 inches and the length of side BC is 17 inches. Which of the following could be the length of side AC?
Answer:
16 inches
Step-by-step explanation:
The length of the side AC is 16 inches.
Calculation of the length of side AC:
Since
we know that two side lengths of a triangle as x and y (x greater than y), the third side z should satisfy the inequality
So, it can be like
x - y ≤ z ≤ x + y
Also,
The side lengths are x=17 and y=10,
So,
17 - 10 ≤ z ≤ 17 + 10
7 ≤ z ≤ 27
Therefore, the AC should be 16 inches.

Answer:
y - 1 = -3(x - 5)Step-by-step explanation:
An equation in point-slope form of the line that passes through the point (x₁,y₁) and has a slope of m:
y - y₁ = m(x - x₁)
m = -3
(5, 1) ⇒ x₁ = 5, y₁ = 1

Given:
A figure of a right angle triangle.
To find:
The value of x to the nearest hundredth.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
In the given triangle,
[tex]\tan 62^\circ=\dfrac{x}{35}[/tex]
[tex]1.8807=\dfrac{x}{35}[/tex]
[tex]1.88073\times 35=x[/tex]
[tex]65.82555=x[/tex]
Approx the value to the nearest hundredth (two decimal place).
[tex]x\approx 65.83[/tex]
Therefore, the value of x is 65.83 units.
