Answer 2

Answer:

third option

Step-by-step explanation:

Given that x = - 2 + [tex]\sqrt{8}[/tex] is a root

Complex roots always occur as conjugate pairs , thus

x = - 2 + [tex]\sqrt{8}[/tex] is a root then x = - 2 - [tex]\sqrt{8}[/tex] is a root

The required factor is then

(x - (- 2 - [tex]\sqrt{8}[/tex] ) )

A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B ​

Answers

Answer:

A=50, B=4

A is directly proportional to the square root of B

name the constant 'k'

A = k*B^0.5

50 = k*4^0.5

50=2k

k=25

=> A =25 root B

i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)

A written in terms of B is 25√B.

What is direct and inverse proportion ?

In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.

According to the given question A is directly proportional to the square root of B.

∴ A = K[tex]\sqrt{B}[/tex]

Given when A = 50 B = 4.

50 = K[tex]\sqrt{4}[/tex]

50 = 2k

k = 25.

So, A =25√B.

The circumference of a circular garden is 75.36 feet. What is the radius of the garden

Answers

Answer:

12 rounded to a whole number.

Step-by-step explanation:

75.36 divided by pi (3.14159) = 23.987. this is diameter (the length from one side of a circle to the other).

but we need to find the radius. the radius is half way across a circle.

23.987 divided by 2 = 11.993.

round this to a significant whole number and you get 12.

The radius of the garden is,

⇒ r = 12

We have to given that;

The circumference of a circular garden is,

⇒ C =  75.36 feet.

Since, We know that;

The circumference of a circle is,

⇒ C = 2πr

Substitute given values,

⇒ 75.36 = 2 × 3.14 × r

⇒ 75.36 = 6.28 r

⇒ r = 12

Thus,  the radius of the garden is,

⇒ r = 12

Jenny and her children went to the SeaWorld.She purchased adult ticket for herself and children tickets for her 2 boys. Tickets cost $39.99 for one adult and $19.99 for each child. Let x represent the number of adult ticket purchase and y represent the number of child tickets purchase. Write an expression to represent the total cost of the tickets Jenny purchased

Answers

Given:

She purchased adult ticket for herself and children tickets for her 2 boys.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

To find:

The expression to represent the total cost of the tickets Jenny purchased.

Solution:

Let x represent the number of adult ticket purchase

and y represent the number of child tickets purchase.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

Total cost = 39.99x + 19.99y

Therefore, the expression for total cost is 39.99x + 19.99y.

She purchased one adult ticket and 2 child tickets.

Substitute x=1 and y=2 in the above expression.

Total cost = 39.99(1) + 19.99(2)

               = 39.99 + 39.98

               = 79.97

Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.

T=38

Step-by-step explanation:

t−8+13=43

Step 1: Simplify both sides of the equation.

t−8+13=43

t+−8+13=43

(t)+(−8+13)=43(Combine Like Terms)

t+5=43

t+5=43

Step 2: Subtract 5 from both sides.

t+5−5=43−5

t=38

Answer:

Answers

Answer:

The length will be multiplied by 2.

Step-by-step explanation:

By looking at the first and third ratio, we know that the no. of birck have been multiplied by 2 and the length has also been multiplied by 2 .

So when the number of bricks is multiplied by 2, the length is multiplied by 2

Answer:

2

Step-by-step explanation:

Using the table we observe the points

(6, 3) and (12, 6)

The number of bricks doubled

6*2 = 12, and

The length is doubled accordingly

3*2 = 6

So the answer is 2

how many quarters make 40 dollars


can you work it out with quarters
help me please help me please help me please​

Answers

Given problem;

  Number of quarters in $40;

   

To solve this problem;

Convert the dollar value to cents;  

                 100cents  = $1

               In $40, we would have;  40 x 100 = 4000cents

1 quarter = 25 cents

   So, divide 4000cents by 25 to obtain the number of quarters in that amount of dollars;

      Number of quarters = [tex]\frac{4000}{25}[/tex]   = 160

So there are 160 quarters in $40

Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)

Answers

Answer:

Slope: undefined

Equation: x=-3

Step-by-step explanation:

To find the line that passes through the points, you first want to find the slope.  The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.

[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]

We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.

Angle 3 is supplementary to the 95 degree angle, so 180 - 95 = 85.
Angle 3 = 85 degrees

Angle 2 is a vertical angle with Angle 3, so Angle 2 = Angle 3 —> 85=85
Angle 2 = 85 degrees

Angle 1 + 73 degrees is a vertical angle with 95 degrees, so Angle 1 + 73 = 95
Angle 1 = 95 - 73
Angle 1 = 22 degrees

ALSO

Angle 2 + 73 degrees + Angle 1 = 180 degrees
85 + 73 + Angle 1 = 180 degrees
158 + Angle 1 = 180 degrees
Angle 1 = 180-158
Angle 1 = 22 degrees
