Draw triangle ABC by first drawing segment BC six inches long. Then draw a 60° angle at vertex B and a 60° angle at vertex C. Extend the segments so that they intersect at point A.
Answer:
Step-by-step explanation:
Given that segment BC is the base of the triangle, this drawing shows that triangle ABC is an equilateral triangle.
Since;
<B = <C = 60°
Then,
<A + <B + <C = [tex]180^{o}[/tex]
<A + 60° + 60° = [tex]180^{o}[/tex]
<A = [tex]180^{o}[/tex] - [tex]120^{o}[/tex]
= 60°
Thus,
AB = BC = AC = 6 inches

What is the image of (-9,6) after a dilation by a scale factor of 44 centered at the origin?
Answer:
(- 396, 264 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply each of the coordinates of the point by the scale factor, that is
(- 9, 6 ) → ( (- 9 × 44 ), (6 × 44 ) ) = ( - 396, 264 )

Determine the mass of an object, if it requires a force of 6,000 kg: m/s2 to accelerate at the rate of 2 m/s^2
Answer:
The answer is 3000 kgStep-by-step explanation:
The mass of an object can be found by using the formula
[tex]m = \frac{f}{a} \\ [/tex]
f is the force
a is the acceleration
From the question we have
[tex]m = \frac{6000}{2} \\ [/tex]
We have the final answer as
3000 kgHope this helps you
[tex] \boxed{ \red{AnswEr:-}}[/tex]
Mass = 3000 kg★ GivEn :-
Force = 6000 kg • m/s^2Acceleration = 2 m/s^2★ To Find :-
The value of mass★ Solution :-
From Newton's 2nd law of motion we get the equation,
[tex]{ \boxed{ \red{ \sf{F =
m \times a}}}}[/tex]
where,
F = Force m = mass of the objecta = acceleration[tex] \implies \sf \: m = \dfrac{F}{a} [/tex]
Putting the values,
[tex] \implies \sf \: m = \dfrac{6000}{2} [/tex]
[tex] \implies \red{\sf \: m = 3000}[/tex]
Therefore, mass of the object = 3000 kg

Adam, Bethany and Charles played a game.
Adam scored 8 more points than Charles.
Bethany scored 5 more points than Adam.
They scored a total of 72 points.
Find the number of points that Adam, Bethany and Charles each scored.
Points scored by Adam, Bethany and Charles are 25, 17 and 30 respectively.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Given that,
Adam scored 8 more points than Charles,
And Bethany scored 5 more points than Adam.
Also, total score is 72.
Let points scored by Adam is x,
Then point scored by Charles = x-8,
And point scored by Bethany = x+5.
Since, total score = 72
x + x-8 + x+5 = 72
3x - 3 = 72
3x = 75
x = 25
Points scored by Adam is x = 25,
Point scored by Charles = x-8 = 17,
And point scored by Bethany = x+5 = 30.

3/4 (x - 3) - 1/2 2/3 whats the value of x
3/4. x - 3/4 . (-3) -1/2 . 2/3 = 0
3/4x - 2.25 -3/4 = 0
3/4x -2.25 = 3/4
x - 2.25 = (3/4)/(3/4) or just 1
x = 2.25 + 1
x = 3.25
Answer:
probably wrong

Mike spent half of his allowance playing acrade games his parents let him wash the gutters for 5.80 if he ended with 12.20 what is his weekly allowance
Answer:
Weekly allowance (W) = 12.80
Step-by-step explanation:
Given:
Ended amount = 12.20
Amount for guitar wash = 5.80
Find:
Weekly allowance (W)
Computation:
W + 5.80 - W/2 = 12.20
W + 5.80 - 0.5W = 12.20
0.5 W = 6.4
Weekly allowance (W) = 12.80
