When you need to round a number. First you need to look at the placement number that the question is asking to round to the nearest.
In this case it's the nearest tenths.
.8 is in the tenths place.
Now look to the number to the right of that number 3 that's the number that tells you if you will round up or down.
If the number is 5 or more you round up, if it's less than 5 you round down.
In this case the 3 is less than 5 so you round down.
So your answer would be 8.8
Hope this helps.
Answer:
it is 3.2
Step-by-step explanation:
Answer:
cosine, amplitude=2 and period of 2pi/3 is shown in figure 1.
Step-by-step explanation:
cosine α = Adjacent Side/Hypotenuse
Since its amplitude is 2 . So the value of cosine function at COSIN 0 will be 2 and its period will be 2pi/3.
The above described situation is rightly depicted in figure 1.

Answer:
# 1
Step-by-step explanation:
It is number one because if the Period is ( 2pi /3 ) them the middle of the function should be ( pi/3 ) and since the function is a cosine function, the graph should start at the top (2) instead of at 0.

The ratio of dry rice to water is 1 to 2. This means that water is two times more than dry rice. Since the chef uses 9.5 cups of dry rice, the chef needs 19 cups of water.
You can check by using fractions. 9.5 / 19 in simplified form is 1/2, which is 1:2 in ratio.
It would be 9.5:19 just multiply 9.5 by 2
B.)4.5
C.)5.5
D.)7
Answer:
7 cubic yard
Step-by-step explanation:
Let the compost purchased be x cubic yard
And the topsoil purchased be y cubic yard
Hence
x+y=10 ----(A)
Also
Cost incurred in buying compost at a rate of $25 per cubic yards = 25x
Cost incurred in buying topsoil at a rate of $15 per cubic yards = 15y
Total cost incurred = 25x+15y=180
Diving whole equation by 5 we get
5x+3y=36 ----(B)
Multiply A by 3 and subtract it from B
5x+3y=36
- - -
3x+3y=30
_______
2x=6
x=3
Putting this value in A
x+y=10
3+y=10
y=10-3=7
Hence she purchased 7 cubic yards of topsoil.

The value one unit of the bar model is 12
Step-by-step explanation:
The bar is divided into 8 units in the diagram (not available in this question)
We need to find the value of each unit
If x is value of 1 bar,
8x = 96
x = 96/8
So, x = 12
Hence the value one unit of the bar model is 12
