Answer:

1:4

Step-by-step explanation:

If 8/10 prefer Crest, that means 2/10 don't prefer it.

To find the ratio, put together the number that don't prefer it to the number that does:

2:8

Simplify by dividing each side by 2:

1:4

So, the ratio is 1:4

Scrat [10]

It took 60 seconds to fax all documents to Gem

Step-by-step explanation:

The simple addition has to be done to solve the given problem

Given

total faxes = 4

Time for fax 1: t_1 = 14\ sec

Time for fax 2: t_2 = 19\ sec

Time for fax 3: t_3 = 16\ sec

Time for fax 4: t_4 = 11\ sec

The total time t will be:

t = t_1+t_2+t_3+t_4\\= 14+19+16+11\\= 60\ sec

The ratio of the angle measures of a triangle is 1:3:5. Find the angle measures. Then classify the triangle by its angle measure
ExtremeBDS [4]
A triangle has 180 degrees.  You can find the total sum of the ratio by adding its parts together 1+3+5 = 9  Now to find out what each part of the ratio is worth we divide the whole value (180) by the sum of the ratio parts (9)
180/9 = 20

Now we multiply each part of the ratio by 20
1 * 20 = 20
3 * 20 = 60
5 * 20 = 100

Since we have an angle greater than 90 degrees this is an obtuse triangle.
