Answer:
(5, 3 2/3)
Step-by-step explanation:
The centroid is the average of the vertex coordinates:
(A +B +C)/3 = ((2, 3) +(8, 1) +(5, 7))/3 = (2+8+5, 3+1+7)/3 = (5, 3 2/3)
Answer:
46940064
Step-by-step explanation:
1)
The angle of inclination is the angle between the horizontal and the ramp.
Using the sine ratio in the right triangle formed by the ground and the ramp
let x be the angle of inclination, then
sinx = \frac{opposite}{hypotenuse}
hypotenuse
opposite
= \frac{0.7}{4.2}
4.2
0.7
, then
x = sin^{-1}sin
−1
(\frac{0.7}{4.2}
4.2
0.7
) ≈ 10° ( to the nearest degree )
(2)
Again there is a right triangle between the ground and the vertical height of the kite, with hypotenuse being length of string.
let y be the height of the kite and x the horizontal distance, then
sin27° = \frac{opposite}{hypotenuse}
hypotenuse
opposite
= \frac{y}{176}
176
y
( multiply both sides by 176 )
176 × sin27° = y , then
y ≈ 80m ( to the nearest metre ) ← height of kite
and
cos27° = \frac{adjacent}{hypotenuse}
hypotenuse
adjacent
= \frac{x}{176}
176
x
( multiply both sides by 176 )
176 × cos27° = x , then
x ≈ 157m ( to the nearest metre ) ← horizontal distance

Answers
Answer:
307°
Step-by-step explanation:
The sum of all the angles of a hexagon is equal to 900°.
So,
112+x+120+100+128+133 = 900
593+x = 900
x = 900-593
x = 307°
So, the value of x is equal to 307°.

Answer: The given expression (3x − 5) − (4x + 6) = -x - 11.
Step-by-step explanation:
Given : Expression (3x − 5) − (4x + 6).
We have to simplify the given expression.
Consider the given expression (3x − 5) − (4x + 6).
Remove Parentheses ,
we have,
(3x − 5) − (4x + 6) = 3x - 5 - 4x -6
Combining like terms, we have,
LIKE TERMS are terms having same variable with same degree.
here 3x and -4x are like term and -5 and -6 are like terms,
Simplify, we have,
= 3x - 4x - 5 - 6
= -x - 11
Thus, the given expression (3x − 5) − (4x + 6) = -x - 11.

Use the Distributive Property to simplify the expression.
8(12+a)
Answers
[tex]\huge\boxed{\bf{Hi\:there!}}[/tex]
All we have to do to simplify this expression is multiply 8 by 12 and a:
8(12+a)
96+8a
That's our final answer.
[tex]\huge\boxed{\bold{Hope\:it\:helps!\:Good\:luck!}}[/tex]
[tex]\huge\mathfrak{LoveLastsAllEternity}[/tex]
The distributive property is defined as:
a x (b + c) = a x b + a x c
a x (b - c) = a x b - a x c
The final value of the expression 8 x (12 + a) after simplification using the distributive property is 96 + 8a.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
8(12 + a)
We will apply the distributive property.
The distributive property is defined as:
a x (b + c) = a x b + a x c
a x (b - c) = a x b - a x c
Now,
8 x (12 + a ) is in the form of a x (b + c)
So,
8 x (12 + a)
= 8 x 12 + 8 x a
= 96 + 8a
Thus,
The final value of the expression 8 x (12 + a) after simplification using the distributive property is 96 + 8a.

Answer:
JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5Step-by-step explanation:
We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.
1. JKLM ~ QRSP
JK : KL : LM : MJ = 20 : 15 : 24 : 25
QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)
The scale factor is 12/20 = 0.6.
__
2. ΔABC ~ ΔUVT
AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6
UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)
The scale factor is 24/16 = 1.5.
