Answer:
a=3
Step-by-step explanation:
[tex]2a + 6 = 12[/tex]
[tex]2a+6-6=12-6[/tex] ( Subtract 6 from both sides)
[tex]2a=6[/tex] ( Simplify)
[tex]\cfrac{2a}{2}=\cfrac{6}{2}[/tex] (Divide both sides by 2)
[tex]a=3[/tex]

Solving forr
r=(3V
4π)⅓=(3·802
4·π)⅓≈5.76362m
Answer:
r = 5.8 meters
Step-by-step explanation:
The volume formula is V = (4/3)(pi)(r^3), where r is the radius.
Solving for r, we get first 3V = (4pi)(r^3), so that r^3 = (3V)/(4pi)
or in this case, r^3 = 3(802 m^3) / (4pi) = 191.5 meters^3
Taking the cube root of both sides yields r = 5.8 meters
Select all of the equations that are equivalent to `3x+45=180`.
A. 3 (x + 45) = 180
B. 3 (x + 15) = 180
C. 3 (x + 15) = 60
D. x + 15 = 60
E. 3x = 135
Answer:
Option B and Option D
Step-by-step explanation:
B = 3*x = 3x, 3*15 = 45.
D=3* x + 15.
3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We have to solve the equation 3x+45=180
Now isolate x on one side of the equation.
We can do this by subtracting 45 from both sides, giving us 3x=135, and then dividing both sides by 3 to get x=45.
Therefore, the equivalent equations are:
3x = 135
x + 15 = 60
Hence, 3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180

18 meters by 14 meters
Step-by-step explanation:
18 meters by 14 meters
Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).
This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:
2L+2W = 64
Now we know the area enclosed must be 252 so we have:
L* W = 252
Rewriting the second equation we get:
Plug this into first equation to get:
(multiply everything by L)
Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.
Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).

What is the height of the cone.
By examining this image:
⇒ we see a right triangle made up of sidelength of h, 8, and 17
⇒ we know this is a right triangle because there is a little square
⇒between lines of length 8 and h
⇒ which indicates this angle is 90 degrees
⇒ which indicates we have a right triangle
Since we have a right triangle
⇒ we can use the Pythagorean Theorem
Definition of Pythagorean Theorem: square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.*look at the image attached for a better explanation
Now let's form an equation (based on the Pythagorean Theorem)
[tex]h^2 + 8^2 = 17^2\\h^2 = 17^2- 8^2h^2 = 289 - 64 = 225\\h^2 = 225\\h = 15[/tex]
Thus h = 15cm

The probability of rolling 2 even numbers is,
⇒ 1 / 4
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
An experiment involves rolling two dice.
Now, Total possibilities are = 36
And, Number of possibilities to getting even numbers = 9
Hence, The probability of rolling 2 even numbers is,
⇒ 9 / 36
⇒ 1 / 4
Thus, The probability of rolling 2 even numbers is,
⇒ 1 / 4

Answer the following about estimating 321/6.
Answer:
A) 300/6. B) Underestimate.
Step-by-step explanation:
321/6 is 53.5
300/6 is 50
and 360/6 is 60.
50 is closer to 53.5 than 60 is so the closest aproximation would be 300/6

Jackson has a cube. Each edge of the cube is 5 centimeters long.
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Answer:
35.355 cm
Step-by-step explanation:
if u imagine the 3D cut triangle but at a different angle, u would imagine the legnth of the parallelogram being 7.071 which is the hypotenuse of the triangle... along with the hypotenuse given, they also gave the side lenght of the parallelogram which is 5cm... 5 x 7.071 = 35.355 cm
