Answers
Answer:
yes it is correct tq
Step-by-step explanation:
my friend
Answer:
10 quarts.
Step-by-step explanation:
Work with amounts of pure acid.
There is 0.10*3 quarts of pure acid in the 10% solution.
3*0.10 + 0.75x = 0.60(x + 3) where x is the number of quarts of 75% acid.
0.30 + 0.75x = 0.60x + 1.8
0.15x = 1.5
x = 10 .

Answers
Step-by-step explanation:
What is the question asking?
The question is asking for the minium number of cups Lauren needs to sell
Total in profits they need to make?
They need to make 183$ because 175 + 8 = 183
183 / 2.5 = 73.2
because we need to sell at least 183$ worth we need to sell 74 cups or else we will not be making it all the way there.

Step-by-step explanation:
Answer:
x = 3, y = -2.
Step-by-step explanation:
5x + 6y = 3
2x - 3y = 12 Multiply this by 2:
4x - 6y = 24 Now add this to the first equation:
9x = 27
x = 3.
Substitute x = 3 in the second equation:
2(3) - 3y = 12
-3y = 12 - 6 = 6
y = 6 / -3
y = -2.

My house is 20 miles from yours, but on the map it is only 4 mm away.
What is the scale of the map?
A. 1 mm = 5 mi
B. 1 mm = 20 mi
C. 1 mi= 20 mm
D. 20 mm = 4 mi
E. 5 mi = 4 mm
Answers
Answer:
A. 1mm = 5mi
Step-by-step explanation:
20 mi divided by 4 mm would simplify down to 5 mi per 1mm. If there is 4 mm then there is 5mi*4mm which equals out to 4 mm = 20 mi.
A scale of the map is the relationship between the distance on the map to the actual distance. The scale of the map is 1 mm: 5 miles (ml). Thus the option A is the correct option.
To find out the scale of the map, we have to know about scaling of map.
What is the scaling of map?
The scaling of map is the ratio or relationship between the distance of the map to the original distance.
Given information-
The distance of the two houses on the ground is 20 miles.
The distance of the two houses on the map is 4 mm.
Suppose the scale of the map is [tex]s[/tex].
As the 20 miles distance on the ground is same as the 4 mm distance on the map.
Thus the scale of the map can be given as,
[tex]s=\dfrac{4\rm mm}{20\rm miles} \\s=\dfrac{1\rm mm}{5\rm miles}[/tex]
Hence the scale of the map is 1 mm: 5 miles (ml). Thus the option A is the correct option.
