Answer: Choice A) 2/3 of a pound

===========================================

Here's one way to think of it

Imagine you had a cake that is cut into thirds (see figure 1 below). One full cake has 3 pieces. So three full cakes have 3*3 = 9 slices all together.

This means 3 = 9/3

Add on an extra slice (an extra one-third) and we get 9/3+1/3 = 10/3

So the mixed number 3 & 1/3 is the same as the improper fraction 10/3

---------------

Now refer to figure 2. This is where we group up the ten slices into five groups. So there are 10/5 = 2 slices per container. Each slice is a third, so each container gets 2/3 a pound.

The answer is \frac{2}{3}

3\frac{1}{3 } divided by 5\\ is \frac{2}{3}

xz_007 [3.2K]

Answer:

12.5 pi or 39.26990

Step-by-step explanation:

First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:

\frac{\pi r^2}{2}

We can substitute what we have:

\frac{25\pi }{2}

This gives us:

12.5 pi or 39.26990(Not sure what format you need it in)

Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x
Bingel [31]

Answer:

y = (-3)\, x + 10.

Step-by-step explanation:

The question requires that the equation should be in the slope-intercept form y = m \, x + c. The m and c in this equation are constants. In particular:

  • m\! would represent the slope of this line (also known as the gradient of this line,) whereas
  • c would be the y-intercept of this line.

The question states that the slope of this line is (-3). Therefore, m = -3. Thus, the equation for this line should be in the form y = (-3)\, x + c.

The value of constant c could be found using the other piece of information: the point (3,\, 1) is in this line. In other words, the solution \text{$x = 3$ and $y = 1$} should satisfy the equation y = (-3)\, x + c.

Substitute \text{$x = 3$ and $y = 1$} into the equation y = (-3)\, x + c and solve for c:

1 = (-3) \times 3 + c.

1 = -9 + c.

c = 10.

Hence, y = (-3) \, x + 10 would be the slope-intercept form of the equation of this line.

A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Which statement about the quadrilateral is true? A. ABCD is
Dima020 [189]

Hey There!!

The answer to this is: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Which statement about the quadrilateral is true?" Line BC is parallel to line AD because their slopes is equal i.e. (0 - 0) / (7 - 2) = (5 - 5) / (8 - 3) which gives 0 / 5 = 0 / 5 giving that 0 = 0. We check whether line AB is parallel to line CD. Slope of line AB is given by (0 - 5) / (2 - 3) = -5 / -1 = 5. Slope of line CD is given by (5 - 0) / (8 - 7) = 5 / 1 = 5 We have been able to prove that the opposite sides of the quadrilateral are parallel which means that the quadrilateral is not a trapezoid. Next we check whether the length of the sides are equal. Length of line AB is given by sqrt[(0 - 5)^2 + (2 - 3)^2] = sqrt[(-5)^2 + (-1)^2] = sqrt(25 + 1) = sqrt(26) Length of line BC is given by sqrt[(0 - 0)^2 + (7 - 2)^2] = sqrt[0^2 + 5^2] = sqrt(25) = 5 Length of line CD is given by sqrt[(5 - 0)^2 + (8 - 7)^2] = sqrt[5^2 + 1^2] = sqrt(25 + 1) = sqrt(26) Length of line DA is given by sqrt[(5 - 5)^2 + (8 - 3)^2] = sqrt[0^2 + 5^2] = sqrt(25) = 5 Thus, the length of the sides of the quadrilateral are not equal but opposite sides are equal which means that the quadrilateral is not a rhombus. Finally, we check whether adjacent lines are perpendicular. Recall the for perpendicular lines, the product of their slopes is equal to -1. Slope of line AB = 5 while slope of line BC = 0. The product of their slopes = 5 x 0 = 0 which is not -1, thus the adjacent sides of the quadrilateral are not perpendicular which means that the quadrilateral is not a rectangle. Therefore, ABCD is a parallelogram with non-perpendicular adjacent sides. Thus, For (option A).
