Answer:
1 : 3 : 1
Step-by-step explanation:
1 pitcher of lemonade:
Drink mix = 1 tbs
Cups of sugar = 3
Gallon of water = 1
Ratio = 1 : 3 : 1
How much of each ingredient would he need to make 4 pitchers of lemonade?
Multiply all ingredients by 4
Drink mix = 4 tbs
Cups of sugar = 12
Gallon of water = 4
What is the new ratio?
4 : 12 : 4
= 1 : 3 : 1
The new ratio = 1 : 3 : 1
Answer:
x = 7
Explaination:
ABC = 40°
and BD bisects the angle so ABD = 20°
so 3x-1=20
solving for x gets us
x = 7
Answer:
The equation is
![f(x) = [\frac{x}{13}]](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5B%5Cfrac%7Bx%7D%7B13%7D%5D)
Where x is the ribbon's length in ft and with [a] we denote the integer part of a real number a.
Step-by-step explanation:
In order to obtain how many pieces of ribbon Lei can make, we have to divide the length of the Ribbon by the length of each piece, which is 13 ft. This means that if we have x ft of ribbon, then Lei can make a total of x/13 pieces.
However, if the result we obtain is not an integer we need to discard the last part of the ribbon that couldnt form and entire piece of 13 ft, therefore, after we divide x by 13, we also need to take the integer part of that division, that is, the biggest integer that is not bigger than x/13. With this information in mind, we obtain that the amount of pieces Lei can make is given by the following formula:
![f(x) = [\frac{x}{13}]](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5B%5Cfrac%7Bx%7D%7B13%7D%5D)
Where [ a ] denotes the integer part of a real number a.
Mean 35.714 Med 38 Mode 44
Step-by-step explanation:
new arrange from lowest to largest numbers
22 27 35 38 40 44 44
mean = plus of all number/ number
= (22+27+35+38+40+44+44)/7
= 35.714
Median = the central value
= 38
Mode = the most frequency
= 44 (2 numbers)
