It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?

Answers

Answer:

7

Step-by-step explanation:

6,300 divide by 900 would equal 7

Answer:

7 beams

Step-by-step explanation:

To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:

6,300 ÷ 900 = 7

So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

Answer:

56π

Step-by-step explanation:

1. Approach

To find the radius of a circle, use the formula;

[tex]A = r^{2}[/tex]π

To find the area of the shaded region, find the area of the larger circle, and then subtract the area of the smaller circle from it.

It is given that the larger circle has a radius of 9, and the smaller has a radius of 5.

2. Area of the larger circle

[tex]A = r^{2}[/tex]π

Substitute in known value (use 3.14 for π)

[tex]A = (9)^{2} * 3.14[/tex]

A = 254.47

3. Area of the smaller circle

[tex]A = r^{2}[/tex]π

Substitute in known value (use 3.14 for π)

[tex]A = (5)^{2} * 3.14[/tex]

A = 78.54

4. Area of the shaded region

Subtract the area of the smaller circle from the area of the larger circle;

254.47 - 78.54 = 175.93

Find the equation of the straight line which passes through the point (2,3) and is
inclined at 30° to the positive direction of the x-axis.

Answers

Answer: y = 1.73*x - 0.46

Step-by-step explanation:

For a linear equation of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we have an angle of A degrees with respect to the x-axis, the slope of the function can be calculated as:

Tan(A) = a.

in this case, we have we have an inclination of 30° to the positive x-axis (measured from the positive y-axis) and we know that the angle between the positive x-axis and the positive y-axis is 90°, then the angle measured from the positive axis will be such that:

A + 30° = 90

A = 90° - 30° = 60°

Then the slope is:

a = Tan(60°) = 1.73

Then we have the equation:

y = 1.73*x + b

And we know that this line passes through the point (2, 3) then we can replace x by 2 and y by 3 in the equation, and find the value of b.

3 = 1.73*2 + b

3 - 1.73*2 = b = -0.46

Then the equation is:

y = 1.73*x - 0.46

write an equation in slope-intercept form perpendicular to the given equation through the given point
Y = -3x + 4
(6,-2)

Answers

Answer:

y = (1/3)x - 4

Step-by-step explanation:

Any line perpendicular to the given equation y = -3x + 4 will have a slope which is the negative reciprocal of -3; that is, +1/3.

Start with the general slope-intercept form y = mx + b.

Insert the coordinates 6 and -2 into y = mx + b:  -2 = (1/3)(6) + b, or

-2 = 2 + b.  Thus, b = -4, and the desired equation is

y = (1/3)x - 4

Please help me find x

Answers

Answer:

x=13

Step-by-step explanation:

According to the question

3x+5x-14=90

8x-14=90

8x=90+14

8x=104

x=104/8

x=13

180 = 90 + 3x + 5x - 14
180 - 90 + 14 = 3x + 5x
104 = 8x
104/8 = x
x = 13

Checking:
3(13) + 90 + 5(13) - 14 = 180
180 = 180
So x=13

Brandon says that the absolute value of a number and the opposite of a number is the same thing. Is Brandon correct? Use examples to help you explain.

Answers

Answer:

No, Brandon is not correct in making that statement

Step-by-step explanation:

No, Brandon is not correct in making that statement. The absolute value of a number is the total distance between that number and 0. Brandon most likely states this because the absolute value of a negative number such as -5 would actually be the opposite, which is 5. This is not true for the absolute value of a positive such as 5, which instead is actually just 5. Meaning that the absolute value of a positive integer is the same value and NOT the opposite.

How many Terminating Zeros are at the end of 631! when this number is multiplied out

Answers

Answer:

3 zeros

Step-by-step explanation:

When The factorial is the product of all integers that are less than or equal to n but that is greater than or equal to 1. so that The factorial value of 0 is by definition equal to 1. so that suppose that For negative integers, factorials are not defined. so we can do The factorial and can be seen as the result of multiplying a sequence of descending natural numbers (such as 3 × 2 × 1).

          Thus The factorial symbol is the exclamation mark !. like this

Using The factorial formula is  

        If n is a natural number greater than or equal to 1, then

             n! = n x (n - 1) x (n - 2) x (n - 3) ... 3 x 2 x 1

When If n = 0, then n! = 1, by convention it. Thus, The factorial of 631 is calculated, through its definition, can we this way: 631! = 631 • 630 • 629 • 628 ... 3 • 2 • 1
