Leticia is cutting a board to make a ramp for her skateboard. The ramp will slope from the ground up to a height of 4 feet. The board will make an angle of 25° with the ground. How long should she cut the board for her ramp? *
1 point



9.46 feet long



4.41 feet long



8.58 feet long



10 feet long

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

The answer is 23

Step-by-step explanation:

First, you need to divide 68 and 4, which will give you 17. Then, add 3. which will give you 20. Then add negative 3 and you should get 23.

Thank me later :)

Answer: 23

Step-by-step explanation: This is because 68 divided by 4 is 17 plus 3 which is 20 and the two negatives make the other 3 positive so add three  and you get 23.

the answer is 5.0

Step-by-step explanation:

The difference between the means of the Andre's and Mandy's classes are 1.42. \(X_{AM}=1.42X_{MM}\)

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

From the data given we will calculate the mean of andres's class students and mandy's class students.

For Andre's

\(X_{AM}=\dfrac{20+21+22+23+25}{5}=22.5\)

For Mandy

\(X_{MM}=\dfrac{14+15+15+16+19}{5}=15.8\)

So here we will compare the means

\(\dfrac{X_{AM}}{X_{MM}}=\dfrac{22.5}{15.8}=1.42\)

\(X_{AM}=1.42X_{MM}\)

Step-by-step explanation:

Square Root of 48: √48 = 6.928Square of 48: 482 = 2304

Answer:

6.8 or 6.9 (Estimation).

Step-by-step explanation:

The number 48 is not a perfect square. Using the approximation approach, we can get the square root of 48. We may utilize the long division approach to get an exact result. We discover square numbers close to 48 using the approximation approach. We can see that 36 and 49 are perfect square numbers that are close to 48. 36 has a square root of 6 while 49 has a square root of 7. As a result, the square root of 48 must be between 6 and 7, and preferably closer to 7 because 48 is closer to 49. This approach simply provides an approximation. We may use the long division approach to determine a more precise decimal number for 48.

Answer:

375 seats are filled.

Step-by-step explanation:

The first step is to convert three fourths into a decimal.

In order to do so, I need to divide the numerator and the denominator.

3 ÷ 4 = 0.75

Now we need to multiply 0.75 by 500 beacause 0.75 were the number of seats filled and 500 was the number of seats.

0.75 x 500 = 375

So 375 seats are filled.
