9 * 25 = 225
225 - 6 = 219
There are 219 chairs left.
Answer:
219 Chairs are left.
Step-by-step explanation:
[tex]\rightarrow[/tex] Each row has 25 chairs. And there are total 9 rows.
So, total number of chairs = 25×9
= 225
➾ Workers removed 6 chairs, so left number of chairs = 225-6
= 219 chairs.

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

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

REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
double the radius:
circumference =
times larger,
area =
times larger;
triple the radius:
circumference =
times larger,
area =
times larger
also explain how u did it for brainliest if its right
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

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

Dylan loves reading. He went to buy books from a bookstore. A school bag and 3 books cost $180. A school bag and 5 books cost $270. How much did each book cost?
School bag _ y
book _ x
system:
y+3x=180
y+5x=270
y=180-3x (and we put that instead of 'y' in the second equation)
(180-3x)+5x=270
180+2x=270
2x=90
x=45
so one book costs $45
and school bag:
y+3×45=180
y+135=180
y=180-135
y=45
Answer:
Each book costed 45$.
Step-by-step explanation:
Let x represent the price of a school bag and y represent the price of a book.
we get the following system of equations:
x+3y=180 (equation 1)
x+5y=270 (equation 2)
using equation 1: x=180-3y
then we substitute x in equation 2 in order to find y:
180-3y+5y=270
180+2y=270
2y=270-180=90
y=90/2=45
and we know that y represents the price of a book, so each book costs 45$.

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).

KLMN is a parallelogram.
Answer:
They both are a 90 degree angle.
For the parallelogram KLMN, opposite angles K and M are equal.
What is Parallelogram?Parallelogram are type of quadrilateral in two dimensional geometry which has four sides, four vertices and four angles where opposite sides are equal. They also have the two pairs of sides parallel to each other. These sides are opposite sides.
The sum of the adjacent angles of the parallelogram is equal to 180 degrees and the sum of all angles is equal to 360 degrees. Also the opposite angles are equal.
Given that KLMN is a parallelogram.
Here K and M are opposite vertices and also L and N are opposite vertices.
In a parallelogram, we know that measure of opposite angles will be equal. So here, measure of angles K and M are equal.
Therefore, since angles K and M are opposite angles of the parallelogram, they are equal.

Answer:
x=10
Step-by-step explanation:
so your given an angle, 110, and another with an equation, 8x+30, which happens to be vertical to 110 degree angle meaning they are equal, so they both are equal to 110 now how do you solve for x? you simply reverse the equation that x is in, so you subtract 110-30=80, then divide by 8 giving you 10, so x=10.
Answer:
X = 10, because of the second angle's equation. 8x + 30 hints the solution. 110 - 30 is 80, and 80 / 8x In this case, x can be represented as itself is 10
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

This figure consists of a rectangle and semicircle.
What is the area of this figure?
Use 3.14 for π.
A shape made up of a rectangle of the left and a semicircle on the right. The rectangle has a width of 15 meters and a height of 12 meters.
Enter your answer to the nearest hundredths place in the box.
Question 5 options:
Step-by-step explanation:
l = 12 metres
b = 15 metres
diameter of semicircle = length = 12 m
radius = 12/2 = 6 cm
area of the figure = area of rectangle + area of semi circle
= l × b + πr²
= 12 × 15 + 3.14 × 6²
= 180 + 113.04
= 293.04 m²
The perimeter of the figure is 60.84 meters.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the width and height of the rectangle are 15 meters and 12 meters respectively.
Note that the diamter o he semicircel is 12 meters.
The radius of the semicircle is:
12/2
= 6 meters
The perimeter of the figure is given by:
15 + 12 + 15 + π(6)
= 42 + 3.14×6
= 60.84
Hence, the perimeter of the figure is 60.84 meters.
