Answer:

21.5 square units

Step-by-step explanation:

The 4 circles touching eachother have a total combined length of 20.

There are 4 circles. 20/4 = 5. The diameter of each circle is 5 units.

The length ofthe rectangle is 20 units. the width of the rectangle is 5 units.

The area of the shaded region is the area of the rectangle minus the ares of 4 circles.

A = area of rectangle - area of 4 circles

A = LW - 4 × πr²

The radius of each ciorcle is d/2 = 5/2 = 2.5

A = 20 × 5 - 4 × 3.14 × 2.5²

A = 100 - 78.5

A = 21.5

Step-by-step explanation: Just solve decreasing 15% each year

Answer:

at least 10 visits

Step-by-step explanation:

Given:

75 rewards points for signing up

10.5 points for each visit

Total Number of Points are :

75 + 10.5 · number of visits he makes

How many visits must Tyler make to earn a free movie ticket?

75 + 10.5 · x  ≥ 180 points for a free movie ticket

Where, x is how many visits must Tyler make to earn a free movie ticket

       10.5 · x  ≥ 180 -75

                x  ≥ 105/ 10.5

                 x ≥ 10

Since the number of visits to reach 180 points is 10 then Tyler has to visit the movie theater 10 times or more.

Check our answer:

75 + 10.5 · 10 = 180 will earn him a free movie ticket

The amount saved due to early payment is $19,242

Data;

The total payment for the whole term is the equal to the product of monthly payment and the number of payment as calculated above.

The total amount in cash in case of prepayment is

[tex]total amount in case of prepayment = monthly payment * number completed + balance + penalty[/tex]

The number of payment completed = 12

Balance = $37,546.36

Penalty for prepayment = 300

The amount of prepayment is

Step-by-step explanation:

Givens

pi = 3.14

d = 10 cm

h = 2*d

Formula

The combined formula is given below.

SA = 2*pi*r^2  +  2*pi*r * h

Conversions

d = 10 cm

h = 2*10

h = 20 cm

r = d/2

r = 10 / 2

r = 5cm

Solution

SA = 2*pi*r^2  +  2*pi*r * h

SA = 2*3.14*5^2 + 2*3.14*5*20

SA = 157 + 628

SA = 785 cm^2

All sides add up to the perimeter. The perimeter of the kite is 27 units then the correct option is C.

It is concerned with the geometry, region, and density of various 2D and 3D forms.

The Pythagoras theorem will determine the kite's length (x).

H² = P² + B²

H² = 15² + 8²

H² = 225 + 64

H² = 289

 H = 17

Then

[tex]\rm x = \dfrac{H}{2} \\\\x = \dfrac{17}{2}\\\\x = 8.5[/tex]

And another length of the kite is 5 units.

Then the perimeter of the kite will be

Perimeter = 2(8.5 + 5)

Perimeter = 27

Using it's concept, it is found that there is a 0.643 = 64.3% probability that it will rain in the village on Wednesday.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, considering Monday - Tuesday - Wednesday, the possible outcomes are as follows:

R - R - R(0.7 x 0.7 x 0.7)

R - N - R(0.7 x 0.2 x 0.6)

N - R - R(0.3 x 0.6 x 0.8)

N - N - R(0.3 x 0.4 x 0.6)

Then, the probability is given by:

p = 0.7 x 0.7 x 0.7 + 0.7 x 0.2 x 0.6 + 0.3 x 0.6 x 0.8 + 0.3 x 0.4 x 0.6 = 0.643.

Answer:

[tex](x+4)^2+3=0[/tex]

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: [tex]ax^2+bx+c[/tex]

So order to complete the square, you need to take the [tex]b[/tex] term out of the equation, divide it by two, and then square it

In this case, the [tex]b[/tex] term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

[tex]x^2+8x+16+19=16[/tex]

Now you can simplify the LHS

[tex](x+4)^2 +19=16[/tex]

Now you subtract 16 from both sides

[tex](x+4)^2+3=0[/tex]

So this is as far as you can go since you cannot take the square root of a negative number

Answer:

Area of composite shape = 36 square units

Step-by-step explanation:

Area of composite shape:

Rectangle I:

      Length = 3 units

     width   = 6 - 4 = 2 units

Area of rectangle I = length *width

                                = 3* 2

                                = 6 square units

Rectangle II:

     length = 6 units

     width = 5 units

Area of rectangle II = 6 * 5

                                = 30 square units

Area of composite shape = area of rectangle I + area of rectangle  II

                                          = 6 + 30

                                           = 36 square units

Answer:

x = 98 degrees

Step-by-step explanation:

The sum of angles in a pentagon is 540 degrees. You can find this with the formula where n is the number of sides: 180(n-2). This formula will find the angle sum of a polygon. Now, since you know the value of every other angle except X, we can construct the equation 112+100+113+117+x=540

Solving this equation yields x=98 degrees

Sum of angles in a pentagon is 540°

x = 540 - (117+113+100+112)

x = 540 - 442

x = 98°

Yes, at positive x coordinates

Step-by-step explanation:

Find the equation of g(x)

Given ordered pairs of g(x):  (-1, -22)  (0, -20)  (1, -18)

[tex]\sf let\:(x_1,y_1)=(0,-20)[/tex]

[tex]\sf let\:(x_2,y_2)=(1,-18)[/tex]

[tex]\sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-18-(-20)}{1-0}=2[/tex]

Point-slope form of linear function: [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-(-20)=2(x-0)[/tex]

[tex]\implies \sf y=2x-20[/tex]

Substitute the equation of g(x) into the equation of the circle and solve for x

Given equation:  [tex]y^2+x^2=100[/tex]

[tex]\implies (2x-20)^2+x^2=100[/tex]

[tex]\implies 4x^2-80x+400+x^2=100[/tex]

[tex]\implies 5x^2-80x+300=0[/tex]

[tex]\implies x^2-16x+60=0[/tex]

[tex]\implies x^2-10x-6x+60=0[/tex]

[tex]\implies x(x-10)-6(x-10)=0[/tex]

[tex]\implies (x-6)(x-10)=0[/tex]

Therefore:

[tex](x-6)=0 \implies x=6[/tex]

[tex](x-10)=0 \implies x=10[/tex]

So the linear function g(x) will intersect the equation of the circle at positive x coordinates.

Answer:

f = 79

Step-by-step explanation:

You need to perform one-step equations process

146 + f = 225 (You're trying to solve for "f")

*First way, you could subtract both sides by 146 which makes the 146 cancel out then do 225-146 = 79. So f is 79

*A rule to remember is that the opposite of addition is subtraction. If you move 146 to 225 side you must switch it to negative 146.
