Solve the following proportion? 5/10 = 8/w

Kipish [7]

Answer:

Step-by-step explanation:

solve the following proportion?

5/10 = 8/w

5 : 10 = 8 : w

w = (10 * 8) : 5

w = 80 : 5

w = 16

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

check

5 : 10 = 8 : 16

0.5 = 0.5

The answer is good

I have a question that says " jada has read 3/5 of a book. She has read 75 pages so far. How many pages are in the whole book?"

jok3333 [9.3K]

Answer and Step-by-step explanation:

To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.

The reciprocal means the the value, but flipped, so $\frac{3}{5}$ will become $\frac{5}{3}$ .

Now we do 75 times $\frac{5}{3}$ /

$\frac{75 * 5}{3} \\\\\\\\\frac{375}{3} \\\\\\\\125$

So, there are 125 total pages in the book.

An angle bisector always creates two acute angles. find a counterexample to show that the conjecture is false.

sweet-ann [11.9K]

An acute angle is an angle that is less than 90°. An angle bisector is a ray drawn along an angle that bisects it into two equal and adjacent parts. Now, if the total angle is, say 270°, which is more than a half circle, it would result to two 135-degree angles. In this case, the angle is no longer acute, but obtuse.

The difference of the quotient m and 9 and the quotient of n and 30

Zanzabum

Answer: (30m-9n)/270

First we start with m/9-n/30.

We multiply the denominators to get 270.

Then we multiply the numerators by the original denominators to get (30m-9n).

To check, we can use m=2, and n=4

2/9-4/30=4/45

(30*2-9*4)/270=24/270=4/45

What is the difference between a ray and line segment line segment is a part of a line bound by multiple points along the line;

koban [17]

A line segment is a part of a line bound by two points; a ray is a line with one endpoint that extends to infinity in one direction. is the difference between a ray and line segment.

Option: C.

Step-by-step explanation:

A line is a set of multiple points that extends from one point to its opposite direction without any end. Ray and Line segments are the two parts that can occur in a line.

A ray is a line with an endpoint in which the line can be extended from that point to infinity in a direction. A line segment also another part line and it consists of two points. Moreover, The line is bounded between those points.
