Find 4/7 divided by 7/8

Reika [66]

If you divide a fraction by another fraction, this is equivalent to mupltiplying by its inverse:

so $\frac{4}{7}$ divided by $\frac{7}{8}$

is equivalent to

$\frac{4}{7}$ multiplied by by $\frac{7}{8}$

which is

$\frac{4}{7}* \frac{7}{8}= \frac{4*7}{7*8}= \frac{4}{8}= \frac{1}{2}$

so the answer is $\frac{1}{2}$ which is also 0.5

Line AB goes through the points A (0, –4) and B (6, 2). Which equation represents line AB?

insens350 [35]

Answer:

Option C) y + 4 = x

Step-by-step explanation:

We are given the following information in the question:

Line AB goes through the points A (0, –4) and B (6, 2).

We can use the two-point form of equation of straight line.

The equation of line is given by:

$(y-y_1) = \displaystyle\frac{y_2-y_2}{x_2-x_1}(x-x_1)$

where, $(x_1,y_1), (x_2.y_2)$ is the point through which the line passes.

The equation of line is:

$(y+4) = \displaystyle\frac{2+4}{6-0}(x-0)\\\\(y+4)= x\\y = x-4$

Thus, the equation of line AB is given by Option C) y + 4 = x

John who is 5 ft tall is standing 20 feet away from a tree, and you measure the angle of elevation to be 38∘. How tall is the tr

fenix001 [56]

Answer:

The tree is 20.6 ft tall.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.

The diagram makes a right-angled triangle.

Given the angle = Ф = 38⁰

Adjacent = a = 5 ft

Opposite = b = 20 ft

Hypotenuse = Tree length = c ?

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

$\:c=\sqrt{a^2+b^2}$

substituting a=5, b=20

$c=\sqrt{5^2+20^2}$

$c=5\sqrt{17}$

$c=20.6$ ft

Thus, the tree is 20.6 ft tall.

You have a map of an area in France. The scale used is 2cm:8km. You want to ride to a national park. The park is shown on the ma

slega [8]

Divide the distance on the map by 2 to get the number of 8km segments there are, then multiply that by 8km for total distance.

16 cm / 2cm = 8

8 x 8km = 64km total.
