In engineering, equilateral triangles can support the most weight and so are commonly found in the design of bridges and buildings. Equilateral triangles are triangles with three congruent sides and three congruent angles. What are the measures of the angles of an equilateral triangle?
Answer:
Hey mate....
Step-by-step explanation:
This is your answer....
Yes, because a equilateral triangle has 3 equal angles. The 3 angles of a triangle equal 180°. So if the angles are all equal in an equilateral triangle, we do 60 times 3 which equals 180°.

What is equivalent to 7 x 7 x 7 x 7 x7 x 7? 7 (5 as exponent), 7 (6 as exponent), 6 (7 as exponent), 7 (7 as exponent).
Answer:
7 (6 as exponent)
Step-by-step explanation:
Given the repeated product of a number to be expressed in exponential terms, we take the number as the base and the number of times it is multiplied as the exponent or power.
As such, given 7 x 7 x 7 x 7 x7 x 7
the base is 7 and since the number of 7s being multiplied is 6, the result is
7 exponent 6 which may be written as 7^6
Answer:
Step-by-step explanation:
7^6

A farmer has just tilled her 51-yard by 68-yard field. To survey her field, the farmer begins in one corner and walks the length of the field. She then turns and walks the width before crossing diagonally across the field to the original corner. How far does the farmer walk?
Answer: l +w+ hypotenuse or 204
Step-by-step explanation: so the farmer walks the length then the width of the field then the diagonal which we don't know using pythagorean to find that last side then add the values 51^2+68^2=c^2 and 51+68+85= 204

A package designer wants the hexagonal base of a hat box to have an area of
about 200 in.2. About how long is each side?
Answer:
About 9inches long
Step-by-step explanation:
Area of a hexagon = 3√3/2 a²
a is the length of each side
Given
Area of the hexagon = 200in²
Substitute
200 = 3√3/2 a²
200×2 = 3√3 a²
400 = 3√3a²
a² = 400/3√3
a² = 400/5.196
a² = 76.982
a = √76.982
a = 8.774
Hence the length of each side is about 9inches long (to nearest inches)
amelia paid 360 for a watch after he had been allowed a discount 10% discount what was the marked price of the watch? and also put the formula
Answer:
$396

enough drinks for 28 people, how many cups of orange juice will she
need? *
Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.
Each square is one square unit. Sienna uses the same square units to draw a 6 x 2 rectangle and says that it has the same area as the 3 x 4 rectangle. Is she correct?

Select the equation and solution for the problem. Let x represent the unknown number.
A total of 15 people on a sports team are riding in 3 vans. How many people are riding in each van if each van is carrying the same number of people?
Answer:
C
Step-by-step explanation:
So your total is 15. There are 3 vans, and we want to know how many are on each van.
3 (number of people on each van)=15
Number of people are unknown
3x=15
Divide both sides by 3 to solve for x
x=5

Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4
simplify fully 4x-8x^2/12x-6
Answer:
- [tex]\frac{2}{3}[/tex] x
Step-by-step explanation:
Given
[tex]\frac{4x-8x^2}{12x-6}[/tex] ← factorise numerator and denominator
= [tex]\frac{4x(1-2x)}{6(2x-1)}[/tex] ← factor out - 1 from (1 - 2x) on numerator
= [tex]\frac{-4x(2x-1)}{6(2x-1)}[/tex] ← cancel the common factor (2x - 1)
= [tex]\frac{-4x}{6}[/tex] ← cancel 4 and 6 by 2
= - [tex]\frac{2}{3}[/tex] x
Simplifying the expression will give us: [tex]\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}[/tex]
Given the expression, [tex]\frac{4x-8x^2}{12x-6}[/tex], we are required to simplify the expression as follows:
Step 1: Factorize the denominator and the numerator.
[tex]\frac{4x-8x^2}{12x-6}\\\\=\frac{(1 - 2x)4x}{(2x - 1)6}[/tex]
Step 2: Rewrite the fraction by factoring out -1 from the numerator.
[tex]=\frac{(2x - 1)-4x}{(2x - 1)6}[/tex]
Step 3: Divide the numerator and denominator by (2x - 1) respectively.
[tex]=\frac{-4x}{6}[/tex]
Step 4: Divide the numerator and denominator by 2 respectively.
[tex]=\frac{-2x}{3}[/tex]
Therefore, simplifying the expression will give us: [tex]\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}[/tex]
