Step-by-step explanation:

Answer:

The number of pencils that needs to be placed at the other 1 inch end to get a balance again is approximately 3 pencils

Step-by-step explanation:

The given parameters are;

The length of the ruler used as a seesaw = 12 inch

The location where the pencil is placed = Under the 4 inch mark

The location where the weight is placed to balance the seesaw = The 2 inch mark

Therefore, the pencil at the 4 inch mark is fulcrum

The location where a pencil is placed on the ruler = The 12 inch end

The number of pencils, x, that needs to be placed at the other 1 inch end to get a balance again is given as follows;

The distance of the pencil at the 12 inch end from the fulcrum = 12 inches - 4 inches = 8 inches

The distance of the pencils placed at the 1 inch end from the fulcrum = 4 inches - 1 inch = 3 inches

Therefore at balance point, (equilibrium) the anticlockwise moment = The clockwise moment, which gives;

The mass of 1 pencil × 8 inches = x × The mass of 1 pencil × 3 inches

x = (The mass of 1 pencil × 8 inches)/(3 inches × The mass of x × 1 pencil)

x = 8/3 = 2.[tex]\overline 6[/tex]  ≈ 3 pencils

The number of pencils that needs to be placed at the other 1 inch end to get a balance again = x ≈ 3 pencils.

[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

where -

According to the question , let the hypotenuse of the triangle be 'c' . So ,

[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]

[tex] = > c = \sqrt{9000000 + 16000000} [/tex]

[tex] = > c = \sqrt{25000000} = 5000[/tex]

Answer:

19/15

Step-by-step explanation:

To solve this, we need to add 2/3 and 3/5, to do this, we need to find the LCM of 3 and 5, that is 15. We multiply 2/3 by 5/5 and 3/5 by 3/3. This gets us 10/15 + 9/15. When we add those together, we get 19/15.

Answer:

Answer:

Step-by-step explanation:

The y-intercept is 10 of the line that passes through the points (2,7) and (6,1).

The equation of a line is found using the slope-intercept form of a straight line. We need to know the slope of the line and the intercept where the line crosses the y-axis in order to use the slope-intercept formula. Consider a straight line with y-intercept b and slope m. For a straight line with slope "m" and y-intercept "b," the slope intercept form equation is: y = mx + b.

Given that the points are (2,7) and (6, 1).

To find the equation, using the slope formula;

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 -7) / (6-2)

m = -6/4

m = -3/2

Now to find the slope intercept form,

y = (-3/2)x + b,

here b is the y-intercept.

Now we will substitute the value of (2,7) in the slope intercept equation.

Hence, b = 10

Therefore, the y-intercept is 10 of the line that passes through the points (2,7) and (6,1).

Step-by-step explanation:

The equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

We're given that:

In 1 hour, she averagely covers 60 miles.

In h hours, she averagely covers [tex]60 \times h[/tex] hours

d = distance remaining for her to reach to her grandmother's home after h hours of driving

d = Total distance - distance traveled in h hours

d = 380 - 60×h

(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, so 60×h can be simply written 60h)

Thus, the equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h
