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).

The probability of rolling 2 even numbers is,

⇒ 1 / 4

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: 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.

100 boxes     28 red    40 green   32 blue

4/10 * 100   = 40       Green

.32 * 100 = 32           Blue

Answer:

They both are a 90 degree angle.

For the parallelogram KLMN, opposite angles K and M are equal.

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: 8.10

Step-by-step explanation: times by each bottle

Answer:

8; 3 : 8

Step-by-step explanation:

to find out how many shapes there are for every 3 circles you must first reduce the ratio down to 3 : blank

divide both sides by 4

3 : 8

that means there are 8 shapes for every 3 circles

the simplified ratio is 3 : 8

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

           *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

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

Solving forr

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

Answer:

Step-by-step explanation:

Turn the mixed numbers to fractions

[tex]\frac{11}{2} *\frac{33}{8}[/tex]

Then multiply both Numerators

11 x 33=363

Also do the same to the Denominators

2 x 8=16

You get  [tex]\frac{363}{16}[/tex]

Simplify and it becomes 22 11/16 or 22.68

Answer:

Surface Area = 2×(3.4×18 + 3.4×30.6 + 18×30.6) = 1432.08 centimeters2

Step-by-step explanation:

Question 1: x=12.5

6x+4x+2x+30=180

(One full line forming a semi circle would equal to 180 degrees all the angles given would therefore equal up to that value)

Add like terms to simplify;

12x+30=180

Use inverse operations to isolate the variable!

180-30=150

150/12=12.5

Check ur work!

6(12.5)+4(12.5)+2(12.5)+30=180

75+50+25+30=180

180=180

Question 2: Angle EAF = 25 degrees

Since x equals 12.5

and the equation given to represent the angle is 2x

2(12.5)=25

Question 3: Angle DAE= 50 degrees

x=12.5

Angle DAE=4x

4(12.5) = 50

Question 4: Angle CAD= 75 degrees

x= 12.5

Angle CAD= 6x

6(12.5) = 75

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$.

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

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
