Answer:

153.86 units²

Step-by-step explanation:

From the question given above, the following data were obtained:

Pi (π) = 3.14

Radius (r) = 7 units

Area (A) =?

The area of a circle can be obtained by using the following formula:

A = πr²

A = 3.14 × 7²

A = 3.14 × 49

A = 153.86 units²

Thus, the area of the circle is 153.86 units²

Answer: B and D

Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080

The point (20 , 800)  and ( 27 , 1080 )lies on the line.

Option (b) and (d) is correct.

It is given that average bill totals for given numbers of diners at Simone's restaurant.

To find which points will lie on the line you get.

Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).

The rate is constant.

Graph this relationship with the number of people along the x-axis and bill amounts along the y axis.

y = mx + c

=> 40 =m+ c

80 = 2m + c

=> m = 40

40 = 40 + c

=> c = 0

Hence

y = 40x

x = 12 => y = 480

x = 20 => y = 800

x =24 => y = 960

x = 27 => y = 1080

x = 28 => y = 1120

Hence (20 , 800) and ( 27 , 1080 ) point lies on the line

Answer:

I think the answer will be y=3/5x-3

Answer:

y = 3/5x - 3

Step-by-step explanation:

Slope-intercept form is y = mx + b.

For this question, all you need to do is move some stuff around!

In slope intercept form, the x is on the right side, so you would first subtract x from both sides.

3x - 5y = 15

Next, you would divide both sides of the equation by -5 to get y by itself.

-5y = 15 - 3x

Finally, rearrange the equation. y = mx + b

y = -3 + 3/5x

y = 3/5x - 3

Answer:

126

Step-by-step explanation:

Angle SRW is supplementary to (2x + 18)º and (3x)º, that is, they add up to 180º.

Finding angles in function of X:

Since angles (2x + 18)º and (3x)º are opposite by vertex R, they have the same measure. So

[tex]3x = 2x + 18[/tex]

[tex]x = 18[/tex]

So

[tex]3x = 3(18) = 54[/tex]

Angle SRW:

Supplementary with 54. So

54 + SRW = 180

SRW = 180 - 54 = 126

So 126 is the answer.

Answer:

The minimum sample size needed for use of the normal approximation is 50.

Step-by-step explanation:

Suitability of the normal distribution:

In a binomial distribution with parameters n and p, the normal approximation is suitable is:

np >= 5

n(1-p) >= 5

In this question, we have that:

p = 0.9

Since p > 0.5, it means that np > n(1-p). So we have that:

[tex]n(1-p) \geq 5[/tex]

[tex]n(1 - 0.9) \geq 5[/tex]

[tex]0.1n \geq 5[/tex]

[tex]n \geq \frac{5}{0.1}[/tex]

[tex]n \geq 50[/tex]

The minimum sample size needed for use of the normal approximation is 50.

Answer:

AB equals 25

Step-by-step explanation:

1( you take ED and the 5 and say of 5.

2( then you count all the letters that stand for numbers and count them.

3) after you count them how many ever there are then you take that number which was 5 too.

4(after you find that number which is number 5 you multipliy 5 and 5.

5(after you multipliy then you should get 25 because 5x5 is 25.

And there you go thats the answer step by step.

Step-by-step explanation:

Answer:

–59

Step-by-step explanation:

f(x) = -2x - 7

f(x) = -2(-4x + 6) - 7

f(x) = 8x - 12- 7

f(x) = 8x - 19

f(x) = 8(-5) - 19

f(x) = -40 - 19

f(x) = -40 - 19

f(x) = - 59

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the boundary line passes through two point (0,3) and (2,4). So, the equation of boundary line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-3=\dfrac{4-3}{2-0}(x-0)[/tex]

[tex]y-3=\dfrac{1}{2}(x)[/tex]

[tex]y=\dfrac{1}{2}x+3[/tex]

The shaded area lies below the boundary line and the boundary line is a solid line. So, the sign of inequality must be ≤.

The required inequality is

[tex]y\leq \dfrac{1}{2}x+3[/tex]

Therefore, the correct option is B.

Answer: The answer is 530.66

Step-by-step explanation:

I took the test and 81.64 is wrong, It's 530.66

The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².

The area of the circle is pi times the square of the radius of a given circle.

The area of the circle = [tex]\pi r^2[/tex]

A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.

The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.

Now, the area of the circle =  [tex]\pi r^2[/tex]

the area of the circle = 3.14 × 13 × 13

                                   =  530.66 in²

Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

Answer:

y=-2x

Step-by-step explanation:

-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)

use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.

(2n + 1) + (2n + 3) = 88

add like terms.

4n + 4 = 88

4n = 84

n = 21

now plugin.

2(21) + 1

42 + 1

= 43 (the first odd integer)

this means the second one would be 45.

answer: 43 and 45

add them to check:

43 + 45 = 88
