kenji works at a lab with a huge circular particle accelerator. it has a diameter of 8 kilometers. what is the accelerators radius?

Answer:

a = 28

Step-by-step explanation:

Given : t7= 4 , d = -4

Solution : tn = a + (n - 1) d ......( formula)

t7 = a + (7 - 1) (-4)

4 = a + (6)( - 4)

4 = a - 24

4 + 24 = a

28 = a

therefore, the first term (a) is 28.

Answer:

[tex]11x + 18 \leq 40[/tex]

Step-by-step explanation:

She can buy x illy flowers, and each illy flower costs $11.

She wants to buy a pair of red rose flowers for $18 and spend the rest on lly flowers. Each lily flower costs $11.

This means that the total amount she will spend is:

[tex]18 + 11x[/tex]

Amanda has $40 to spend on flowers.

This means that her total spending can be at most $40, which means that:

[tex]11x + 18 \leq 40[/tex]

This is the inequality that models this situation.

Answer:

option A

Step-by-step explanation:

here's your solution

=> 6x - 7y = 28

=> - 7y = 28 - 6x

=> - y = 28/7- 6x/7

=> -y = 4 - 6x/7

=> y = 6x/7 - 4

The length of ladder would be,

⇒ 14/√3 feet

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

You leaned the ladder against your house at a 30° angle of elevation.

And, The foot of the ladder is 7 feet from the foot of the house.

Now,

Let the length of ladder = x

Hence, We can formulate;

⇒ cos 30° = 7 / x

⇒ √3 / 2 = 7 / x

⇒ x = 14 / √3 feet

Thus, The length of ladder would be,

⇒ 14/√3 feet

Statistics are the sets of mathematical equations that we used to analyze the things. It keeps us informed about, what is happening in the world around us. Statistics are important because today we live in the information world and much of this information's are determined mathematically by Statistics Help.

David is 1.94 meters tall.

Given that,

Shaun is 1.88 meters tall.

David is stated to be 6 centimeters taller than Shaun.

To determine David's height, we need to add the additional height to Shaun's height.

Since there are 100 centimeters in a meter, we can convert the 6 centimeters to meters by dividing it by 100: 6 cm / 100 = 0.06 meters.

Now, we can add this height to Shaun's height to find David's height:

1.88 meters + 0.06 meters = 1.94 meters.

Therefore, David is 1.94 meters tall.

Here is my answer. I hope this is helpful.

The required values of x and y are x = -2 and y = 7 in parallelogram PQRS.

To find the values of x and y, we can use the fact that the diagonals of a parallelogram bisect each other. This means that the line segment PT is equal to half of the diagonal PR, and the line segment QT is equal to half of the diagonal QS.

We can set up two equations to represent this information:

PT = 1/2 × PR

QT = 1/2 × QS

Since we are given the lengths of PT and QT, we can substitute those values into the equations:

y = 1/2 × PR

2y = 1/2 × QS

We can then use the fact that the opposite sides of a parallelogram have equal lengths to find the values of PR and QS:

PR = PT + TR = y + (4x + 1)

QS = QT + TS = 2y + (3x + 12)

Substituting these values into the equations above, we get:

y = 1/2 × (y + (4x + 1))

2y = 1/2 × (2y + (3x + 12))

Solving these equations simultaneously will give us the values of x and y.

First, we can solve the second equation for y:

y = (1/2) × (2y + (3x + 12))

y = y + (3x + 12)/2

0 = 3x + 12/2

0 = 3x + 6

-6 = 3x

x = -2

Substituting this value of x into the first equation, we can solve for y:

y = 1/2 * (y + (-2 * 4 + 1))

y = 1/2 * (y - 7)

2y = y - 7

y = 7

Therefore, the values of x and y are x = -2 and y = 7.

Answer:

divide 787 by 3985 then multiply that by 100

Step-by-step explanation:

if it were 100 stamps total and 50 from non US countries, you could pretty easily tell it was half, or 50%  to ge that you need to divide the number in question by the total so 50/100.  which gets .5.  to get the percent you multiply it by 100

so given the numbers we divide 787 by 3985 then multiply that by 100

Answer:

1.59 < 1.73 < 2.061 < 2.1

Step-by-step explanation:

Hello,

We know that 2 is higher than 1. So to pick the first ones we know it won't be the two numbers starting with a 2. We are left with two numbers : 1.73 and 1.59. In this case we can multiply these two numbers by 100. We are allowed to do this only if we do it to all the numbers we are trying to figure out. In this case, it is 1.73 and 1.59 (we are excluding the 2s). So we end up with : 173 and 159. This might help you. We obviously know that 173 is a larger number than 159.

So, we then proceed to the numbers starting with a 2. In this case we can multiply both by 1,000 considering the fact that the number 2.061 has 3 digits after the dot. This will make it easier for us. When we multiply both by 1,000 we end up with 2,061 and 2,100. We obviously know that 2,061 is smaller than 2,100.

I hope this helped
