Is three fourths greater than nine tenths ?

2 answers:

7 0

3/4 = 0.75
9/10 = 0.90

0.90 - 0.75 = 0.15 (which is a positive difference)

this means that 0.90 is greater than 0.75

so the answer is: no, 3/4 is less than 9/10

no when you convert both into decimal 0.75 is smaller than 0.9.

How many degrees does the hour hand turn to get from 12:00 to 12:20

den301095 [7]

So each hour represents 30°.
The minute hand moves 60s per minute and a full rotation is 360° so: 360/60 = 6° per minute.
So in 20 minutes the minute hand will be 6 * 20 = 120° and the hour hand will be 120/12 = 10°.
so it would be 10°

Answer:

AC ≈ 7.3

Step-by-step explanation:

Corresponding sides of similar triangles are proportional.

AC/BC = DF/EF

AC/18 = 15/37 . . . . fill in the given values

AC = 18(15/37) . . . multiply by 18

AC ≈ 7.3

In preperation for an easter egg hunt, 4 blue eggs are filled for every 7 green. How many green eggs will be filled if 100 blue

ivann1987 [24]

Answer:

1. Typed question: 175 green eggs

2. Attached: 22 tables

Step-by-step explanation:

For the question you typed down, it is a ratio and proportion problem. You need to solve for the ratio proportional to the first ratio given.

4 blue eggs are filled for every 7 green. This means that the ratio between blue eggs and green eggs is 4:7.

Now yo need to figure out a ratio proportional to 4:7 if 100 blue eggs were filled. Below is how this is set up:

$\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}$

Now let's solve for x:

$\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}\\\\or\\\\\dfrac{4}{7}=\dfrac{100}{x}\\\\Cross-multiply\\\\4x = (7)(100)\\\\4x = 700\\\\Divide\;both\;sides\;by\;4\\\\\dfrac{4x}{4}=\dfrac{700}{4}\\\\x=175$

For your attached problem:

You have a total of 175 people, you need to figure out how many round tables you need if here are 8 chairs for each table You just need to divide the number of people by the number of chairs per table.

175 ÷ 8 = 21.9 tables

Now since you cannot have half a table, you round up to the nearest whole number. (we round up because you need to make sure that all of them are seated)

21.9 ≅ 22 tables.
