A subtending arc on a circle with a radius of 4.5 centimeters has an arc length of 8π. The measure of the angle subtended by the arc is °.

Answers

Answer 1

Answer: The arc length of a subtending arc on a circle has the formula:
s = rθ
where is the arc length
r is the radius
θ is the angle subtended

So,
θ = s/r = 8π / 4.5 = 16π/9

We multiply it with 180/π to convert it to degrees.
(16π/90) (180/π) = 320°

Answer 2

Answer:

The correct answer

320

63360 inches, and the risers of the steps of the capitol building are 8 inches high. Barry is visiting the capitol, and as he climbs up from the one-mile step, his altitude above sea level, in inches, is given by the following sequence: 63,360, 63,368, 63,376, 63,384, 63,392, ... What is Barry's altitude above sea level, in inches, when he is standing on the 55th step above the one-mile step (counting the one-mile step itself as step #1)?

Answers

This is an arithmetic sequence question
The formula for the nth term of a sequence is 1+(n-1)d where a is the first term(63360), n is the 55th term, d is the common difference between consecutive terms(63368-63360)=8
Altitude on 55th step= 63360+(55-1)8
=63360+(54x8)
=63360+432
=63792 inches

lamar had 2/5 of land. he planted 2/3 of this land with corn. how many acres did he plant with corn? answer in the simplest form

Answers

The answer is 2.5 I think not sure

Final answer:

Lamar planted 4/15 of his land with corn. This was obtained by multiplying the fractions 2/3 and 2/5 to give the fraction of the land that was planted with corn.

Explanation:

To solve this problem, we need to find 2/3 of 2/5. Multiplication of fractions is the best method to use here. Multiply the numerators (top numbers) together and the denominators (bottom numbers) together.

Here are the steps:

First, multiply the numerators: 2 * 2 = 4
Then, multiply the denominators: 3 * 5 = 15
So, 2/3 of 2/5 is equals to 4/15.

In conclusion, if Lamar planted 2/3 of his 2/5 land with corn, he planted 4/15 of the land with corn.

Use elimination to solve this system of equations. 2r + 3s= 9 and 3r + 2s= 12

Answers

2r + 3s= 9 <=> -6r -9s = -27;
3r + 2s= 12 <=> 6r + 4s = 24;
=> 0*r -5*s = -3 => s = 3/5;

2*r + 3*(3/5) = 9<=> 10*r + 9 = 45 <=> 10*r = 36 => r = 18/5;

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.Write about what additional information you would need to create a two-variable equation for the scenario. What kind of problem could you solve with your equation?

Answers

from the information we have now we could write this equation:

ax+by=z
where
a - number of times she played arcade
x- prize of arcade
b- number of times of Ferris wheel
y- prize of Ferris
z- the whole allowance

so in order to make it a two-variable equasion we need to know the value of three more variables.

If let's say we know a, b, and z we could solve the problem of how much cheaper/more expensive the arcade is than ferris wheel (we could find something like x=2y, for example ( we don't know yet, we need more variables) so we'd know that one game is more expensive than the other.

Sample Response: To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.
