there are 3 shape. 2 rectangles and a triangle
to find the area for the rectangle is length x width
to find the area of a triangle its 1/2 x base x height
the small rectangle
4*1.5=6
the bigger rectangle
3*4=12
the triangle
1/2*4*3
1/2*12=6
Add them all up and you get 24

Step-by-step explanation:
2y/3 + 1/3 = y/2 + 1/6
We want to eliminate the fractions
The least common multiple of 3,2 and 6 is 6
Multiply each side by 6 to get rid of the fractions
6(2y/3 + 1/3) = 6(y/2 + 1/6)

Which equations are true?
Choose all answers that apply:
Ⓐ 0 = 0+1-2
Ⓑ 0=(-2)-(-2) +0
Ⓒ None of the above
Answers
Answer:
B
Step-by-step explanation:
A is false. 0 + 1 - 2 = -1, not 0.
B is true.
(-2)-(-2) +0
= -2 + 2 + 0
= 0
C is false, since B is true.
Equation B 0=(-2)-(-2) +0 is true, which is simplified by subtraction.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
For equation A:
0 = 0+1-2
We can simplify the right-hand side of the equation by combining like terms:
0 = -1
This is not true, so we might be tempted to say that equation A is false.
For equation B:
0 = (-2)-(-2) + 0
We can simplify the right-hand side of the equation by performing the subtraction:
0 = 0 + 0 + 0
This simplifies to:
0 = 0
This equation is true.
Therefore, equation B is true.

The linear momentum is a constant when the mass varies inversely of the velocity. If the velocity is 16 meters per second and the object weighs 450 kilograms, what is the weight for an object with a velocity of 12 meters per second?
400 kilograms
600 kilograms
6,400 kilograms
7,200 kilograms
Answers
Answer:
the weight for an object with a velocity of 12 meters per second is 600 kilograms
Step-by-step explanation:
The linear momentum of an article is : p = mv
Where p = Momentum
m = mass
v = velocity
The velocity is 16 meters per second and the object weighs 450 kilograms
So, [tex]p = 450 \times 16[/tex]
We are supposed to find the weight for an object with a velocity of 12 meters per second
So, p = 12m
We are given that the linear momentum is a constant when the mass varies inversely of the velocity.
So, [tex]450 \times 16 = 12 \times m\\\frac{450 \times 16}{12}=m\\600=m[/tex]
Hence the weight for an object with a velocity of 12 meters per second is 600 kilograms
using SOH CAH TOA, solve for x.
Answers
Answer:
x=10.93 or 10.9
Step-by-step explanation:
To find x we use sin
sin(40) = 0.6427876097 then * 17
= 10.9273
= 11
We can check and plug in answer as inverse to find other side
11/sin (40degree) x (90 degree) = 17.11
If we plug in the original 10.9273 we actually find 17
So we should show the correct amount 10.9273 and if rounding try 10.93
10.93/sin (40 degree) x sin (90 degree) = 17.00
