PLEASE ANSWER ASAP

Step-by-step explanation:

subtract the areas of a circle from the area of a square and divide by 4

A_square = L x W

A_circle = pi x r^2

L, W= 12cm

r= 12/2cm

(A_square - A_circle) / 4

divide by 4 since the remaining portions are symmetrical

Answer:

$42.14

Step-by-step explanation:

Given data

Cost of meal= $98

tax= 9%

Tip= 20%

Let us find the amount of the tax and the tip

Tax

=9/100*98

=0.09*98

=$8.82

Tip

=20/100*98

=0.2*98

=$19.6

Hence the total amount paid is

=98+8.82+19.6

=126.42

The amount paid by Pryia

=126.42/3

=$42.14

Answer:

Step-by-step explanation:

How many questions are on the exam?  Represent this by n.

Then 40% of n comes out to 12 questions, or more symbolically,

               0.40n = 12, after which we get n = 12/0.40 = 30

Answers:

(1)  0.40n = 12 is the desired equation.

(2) n = 30 is the number of questions on the exam.

(3) See above for explanations.

Answer:

2,200

Step-by-step explanation:

Number of hours amusement park opens = 11 hours

Number of people who ride the swing in one hour = approximately 200

what is the maximum amount of people that can ride the swing in one day?

Number of people that can ride the swing in one day = Number of hours amusement park opens × Number of people who ride the swing in one hour

= 11 × 200

= 2,200 approximately

Number of people that can ride the swing in one day = 2,200

120.

Trust me.  It is correct using a formula.

Answer:

x ∈ ( - ∞ , 20 )

Step-by-step explanation:

Given :

x / 4 + 6 < 11

Adding - 11 both we get:

= > x / 4 + 6 - 11 < 11 - 11

= > x / 4 - 5 < 0

Multiply by 4 both we get:

= > x - 20 < 0

Adding 20 both side we get:

= > x - 20 + 20 < 20

= > x < 20

Solution set x ∈ ( - ∞ , 20 )

Hence we get required answer!

9514 1404 393

Answer:

  x > -20

Step-by-step explanation:

This is a "2-step" inequality with a negative coefficient.

  x/-4 +6 < 11 . . . . . given

  x/-4 < 5 . . . . . . . . subtract 6 from both sides

  x > -20 . . . . . . . . .multiply both sides by -4

Because the multiplier is negative, the sense of the comparison must be reversed.

_____

Check

  x = -24 should not be in the solution set: -24/-4 +6 < 11 ⇒ 12 < 11 . . . False

  x = -16 should be in the solution set: -16/-4 +6 < 11 ⇒ 10 < 11 . . . True

Answer:

I think i gave u answer for 21 and 23 but ill give ya again :)

21.) x = 0

22.) x = 8

23.) x = 0

24.) x = 12

Step-by-step explanation:

21.) x + 12 = 12

=> x = 0

22.) x - 1 = 7

=> x = 8

23.) 12 + 2x = x + 12

=> 12 + x = 12

=> x = 0

24.) 2x - 14 = 10

=> 2x = 24

=> x = 12

(All of these equations are set equal to their opposite side on the same figure since both the sides are parallel and congruent)

Hope this helps!

Answer:

392

Step-by-step explanation:

V= length x width x height.

V= 14cm×14cm×2cm

V= 392cm^3

Find the volume of the rectangular prism.

Length = 14 cm

Width = 14 cm

Height = 2 cm

Volume = ?

Substituting the values given, in the formula, We get,

⇒ Volume of rectangular prism = 14 × 14 × 2

⇒ Volume of rectangular prism = 392 cm³

The Volume of the rectangular prism is 392 cm³

Answer:

Step-by-step explanation:

The factor that the surface area changes by is 4, the correct option is C.

The lateral surface area of a cylinder is also called the curved surface area of the cylinder.

Suppose that:

Radius of the considered cylinder = 'r' units

Height of the considered cylinder = 'h' units

Then, the lateral surface area of that cylinder is:

[tex]S_L = 2\pi r h \: \rm unit^2[/tex]

We are given that;

The dimensions of the cylinder

Now,

The formula for the surface area of a cylinder is:

SA=2πr2+2πrh

where r is the radius and h is the height of the cylinder. If we double both r and h, we get:

SA′=2π(2r)2+2π(2r)(2h)

Simplifying, we get:

SA′=8πr2+8πrh

Comparing this to the original formula, we can see that the new surface area is four times the old surface area.

Therefore, by the surface area of cylinder answer will be 4.

Let's solve your equation step-by-step.

2x2−5x=7

Step 1: Subtract 7 from both sides.

2x2−5x−7=7−7

2x2−5x−7=0

2x2+−5x+−7=0

Step 2: Use quadratic formula with a=2, b=-5, c=-7.

Answer:

x = 2

Step-by-step explanation:

7x−5=2x+5

step 1 add 5 to each side

-5 + 5 = cancels out

5 + 5 = 10

we now have 7x = 2x + 10

step 2 subtract 2x from each side

2x - 2x cancels out

7x - 2x = 5x

we now have 10 = 5x

step 3 divide each side by 5

5x / 5 = x

10 / 5 = 2

we' re left with x = 2

Answer:

Step-by-step explanation:

Acceleration is defined as the rate of change of velocity.

Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction.

So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).

Answer:

velocity

Step-by-step explanation:

The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

A right triangle has a formula a^2+b^2=c^2 with c being the longest side (hyponotuse). 10 squared is 100, 11 squared is 121, so add those and get 221. 14 squared is only 196 which is not equal to 221 so it is not a right triangle
