Which equation can be used to solve for x?
Choose from the Equation Bank

Answer:

r= 13ft

Step-by-step explanation:

You are looking for the radius

The Area of a circle is  

πr2=530.66

(3.14)r2=530.66

Divide both sides by 3.14

r2=169

Square root both sides to get radius

r=13 feet

In Horace Walpole's The Castle of Otranto, the female characters are predominately presented as passive and emotionally fragile, particularly in contrast to their male counterparts. ... These gendered fictional representations reflect, influence, and perpetuate patriarchal attitudes toward women.

Answer:

X= 1

Hope this helps you!

Answer:

When x = 2, f(x) = 63.

Step-by-step explanation:

In order to find the value of f(x), you have to substitute x = 2 into the function :

[tex]f(x) = - 3 {x}^{2} + 180x - 285[/tex]

[tex]f(2) = - 3{(2)}^{2} + 180(2) - 285[/tex]

[tex]f(2) = - 12 + 360 - 285[/tex]

[tex]f(2) = 63[/tex]

Answer:

Answer:

Ratio of Lacrosse players to Baseball players  is 10:9 or 10/9

Step-by-step explanation:

A ratio can be seen as a relationship between two values which is based on quantitative measures.

To do this simply we divide the values of the quantities that we want to determine the ratio of which on is to the other.

It can be seen as Value of quantity A / Value of quantity B

In this case, quantity A is the Lacrosse players, and it has a value of 10

quantity B represents the Baseball players with a value of 9.

Hence the ratio is  [tex]\frac{10}{9} = 1.1111[/tex]

It can also be written as 10: 9

The decimal is a repeating decimal because the numbers after the decimal points take up a pattern that repeats themselves up to infinity.

Answer: B. Elevator 1 is 18 feet above ground level, and Elevator 2 is 20 feet below ground level.

Step-by-step explanation:

Let "up" be positive and "down" be negative.

Both elevators start at position x = 0

The change in x (Δx) of Elevator 1 is +18 feet, which means it is 18 feet above the origin (which is ground level)

The change in x (Δx) of Elevator 2 is -20 feet, which means it is 20 feet below the origin (which is ground level)

Therefore, Elevator 1 is 18 feet above ground level, while Elevator 2 is 20 feet below

Step-by-step explanation:

Answer:

Infinite

Step-by-step explanation:

2x+y=3

6x=9-3y

Subtract 2x from both sides of the first equation and substitute:

y=3-2x

6x=9-3(3-2x)

6x=9-9+6x

0=0

This equation has infinite solutions. Hope this helps!

Answer:

[tex]proj_uw=6.2i-4.2j[/tex]

Step-by-step explanation:

The projection of a vector [tex]v[/tex] onto a vector [tex]u[/tex] is defined as the projection of the vector [tex]v[/tex] on the line that contains the vector [tex]u[/tex]. It can be calculated  using the following formula:

[tex]proj_uv=\frac{u\cdot v}{||u||^2} u[/tex]

Where:

[tex]u\cdot v[/tex]

Is the dot product between [tex]u[/tex] and [tex]v[/tex] which is given by:

[tex]u\cdot v= $$\sum_{i=1}^{n} u_iv_i= u_1v_1+u_2v_2+...+u_nv_n$$[/tex]

and:

[tex]||u||[/tex]

Is the magnitude of vector which can be calculated as follows:

[tex]||u||=\sqrt{u_1^2+u_2^2+...+u_n^2}[/tex]

In this sense, the projection of vector w onto vector u is:

[tex]proj_uw=\frac{u\cdot w}{||u||^2} u[/tex]

Where the dot product between [tex]u[/tex] and [tex]w[/tex] is:

[tex]u\cdot w =(9*19)+(-6*15)=171-90=81[/tex]

And the magnitude of [tex]u[/tex] is:

[tex]||u||=\sqrt{9^2+(-6)^2} = 3 \sqrt{13}[/tex]

Thus:

[tex]proj_uw=\frac{u\cdot w}{||u||^2} u=\frac{81}{117} \langle9,-6\rangle=\langle6.23,-4.15\rangle\approx6.2i-4.2j[/tex]

Answer:

3 hours

26 baskets each giving a total of 52 baskets

Step-by-step explanation:

Jack has already  filled 11 baskets with apples and is filling them at a rate of 5 baskets per hour. This means that in x hours he would have filled an additional 5x basket to the initial 11 baskets. Therefore the number of baskets that Jack would have filled in x hours can be given by:

11 + 5x

Emma has already  filled 8 baskets with apples and is filling them at a rate of 6 baskets per hour. This means that in x hours he would have filled an additional 6x basket to the initial 11 baskets. Therefore the total number of baskets that Emma would have filled in x hours can be given by:

8 + 6x.

The time it would take Emma and Jack to have completed the same number of baskets can be gotten by using this equation and solving for x:

11 + 5x = 8 + 6x

11 - 8 = 6x - 5x

x = 3 hours.

It would take them 3 hours to fill the same number of baskets.

The number of fruits Jack would have picked in 3 hours = 11 + 5(3) = 26 baskets.

The number of fruits Emma would have picked in 3 hours = 8 + 6(3) = 26 baskets.

Both Emma and Jack would have picked 26 baskets each, giving a total of 52 baskets

Answer:

362 kilometre

Step-by-step explanation:

Let a be the total cost of a journey

let b represent the total distance of a journey

$1.75 is a fixed charge of a journey

the additional charge is $0.10 for b distance ,hence total of additional charge is $.10 multiplied by b i.e 0.1 b

a=1.75+0.1b

a =37.90

37.90=1.75+0.1b

0.1b=37.90-1.75

0.1 b=36.15

b=36.15 /0.10

b=361.5

b=362 kilometre

For the journey that cost 21.80

21.80=1.75+0.1 b

0.1 b=21.80-1.75

0.1 b=20.05

b=20.05 /0.1

b=200.5

b =201 kilometre

Answer:

please there are no data sets, i can't see them

Answer:

a

Step-by-step explanation:

Answer:

I don't think it can, because the two smaller sides cannot have a sum of less than the third side. 6+6=12, and 12 is less than 15, so it cannot be possible. You can even test this out on a piece of paper and you will see that it is not possible.

Answer:yes

Step-by-step explanation:

because 6,6 can be /\ and 15 is __ so it would be /_\....it would be a triangle

Answer:

C. a = 3

b = 7

c = -20

Step-by-step explanation:

x = -b+/- (sq) b^2 - 4ac.

Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0

S if you use your equation : 3x^2 = 20 - 7x

First you have to move everything to one side.

So it'll look like this:

3x^2 = 20 - 7x

-20      -20

3x^2 - 20 = -7x

+7x  +7x

3x^2 - 20 + 7x = 0

don't forget that... Ax^2 +Bx+ C= 0

3 = A

7 = B

-20 = C
