The volume is 8/45 so a•b•c=8/45
So 2/3•1/3•a=8/45
Multiply 2/3•1/3=0.222222 or 2/9
So 2/9•a=8/45
Divide 8/45 / 2/9= 0.8
a=0.8
Hope this makes sense and it helps!!

Answer:
13 to 12
Step-by-step explanation:
Since we're supposed to find the ratio of girls to boys, then let's make a ratio! Remember since they said girls first, we have to start with the number of girls. Since they said boys first, we have to end with the number of boys.
girls to boys
That is our ratio. Now let's plug in the number of girls and boys!!
Girls = 13
Boys = 12
13 to 12
The answer is 13 to 12.

4x + 10 = -26
Subtract 10 from both sides
4x = -36
Divide each side by 4
x = -9
To check it, substitute -9 for x in the original equation.
4(-9) + 10 = -26
-36 + 10 = -26
-26 = -26
Answer:
X=-9
Step-by-step explanation:
4x+10=-26

Determine if 0.68 is rational or irrational and give a reason for your answer.
Answers
0.68 is a rational number because it is a finite decimal number.
0.68 is a rational number because it is a finite decimal number and all finite decimal numbers have undoubtly an equivalent rational number, that is, a real number of the form [tex]\frac{a}{b}[/tex], where [tex]a \in \mathbb{R}[/tex] and [tex]b \in \mathbb{R} - \{0\}[/tex]. In this case, 0.68 is equivalent to the rational number [tex]\frac{68}{10} = \frac{34}{5}[/tex].
In a nutshell, 0.68 is a rational number because it is a finite decimal number.

Object A has gravitational potential energy of 24 joules when it rests on a shelf 5 m above the ground. Does object B have a mass that is three times the mass of Object A. What would be the gravitational potential energy of object B when it rests on a shelf 10 m above the ground?
Answers
The equation for the gravitational potential energy Ep is:
Ep=m*g*h where m is the mass of the body, g=9.81 m/s² and h is the height of the body.
First we need to find the mass of the body:
m=Ep/(g*h)=24/(9.81*3)=0.82 kg
Now lets see what it's gravitational potential energy would be on the height of 1 m.
Ep=0.82*9.81*1 = 8 J
On the height of 1 m the body has a gravitational potential energy of Ep=8 J.

Answer:
C
Step-by-step explanation:
We need to find the area of BOTH the rectangle AND the triangle. So the formula to find area of a triangle is bh[tex]\frac{1}{2\\}[/tex], or bh/2
b- base
h height
And obviously to find area of rectangles and stuff like that is just l x w
So let's find area of the rectangle, AKA the whole,
5x11=55
The area of the rectangle is 55
Now for the triangle,
The base is 5, and the height is 3. 5 x 3 = 15, and 15/2 = 7.5
The area of the triangle is 7.5
Now, subtract because we don't want the area of the triangle BUT the shaded region, so 55-7.5= 47.5 We have to add a unit so its 47.5^2, so the answer is C
