Making a proportion helps solve this problem. Cm on top, km on bottom.
1 9
---- = ----
20 ?
Cross multiply to get 1? = 180
? = 180.
The distance is 180 km.
The conversion of 9 cm on the map to an actual distance, using the given scale of 1 cm for 20 km, results in an actual distance of 180 kilometers.
The question is asking for the actual distance corresponding to 9 cm on the map. According to the given scale on the map, 1 cm corresponds to an actual distance of 20 km. So to find out how many kilometers 9 cm on the map would be in real life, we simply multiply the length measured on the map by the distance each centimeter represents. This gives us:
9 cm * 20 km/cm = 180 km
So, according to the map, 9 cm corresponds to an actual distance of 180 kilometers.

Answer:
x = 19
Step-by-step explanation:
Question: find x such that f(x) = 2/3
Given f(x) = (-1/3) x + 7
equate the value of f(x) to be 2/3
hence,
(2/3) = (-1/3)x + 7 (multiply both sides by 3)
(3) (2/3) = (3) (-1/3)x + (3) 7
2 = -x + 21
x = 21 - 2
x = 19
Answer:
x = 19
Step-by-step explanation:
Answer:
1000/t=w
Step-by-step explanation:
The first thing we need to do is, multiply 1000 to both sides,
c(1000)=wtc
now we need to divide both sides by tc
c(1000))/(tc)=w
The c's on the left side will cancel out
1000/t=w

Answer:
a) The equation of Z and C is Z =K C
b) K = 2
Step-by-step explanation:
Explanation:-
Given data Z is directly proportional to C
⇒ Z ∝ C
⇒ Z = K C
The equation of relating Z and C
Z = K C
Given Z = 20 and C =10
20 = K ( 10)
⇒ K = 2
a. 12 inches
b. 216 inches
c. 412 inches
d. 12/4 inches
It will take the construction company 48 hours to remove 36 tons of dirt from the site.The construction company can remove \( \frac{3}{4} \) tons of dirt from the site each hour.
To find out how long it will take them to remove 36 tons of dirt, we can set up a proportion
Given:Amount of dirt removed in one hour =
Total amount of dirt to be removed = 36 tons
Let t represent the time in hours it will take to remove 36 tons of dirt. Plugging in the values:
Solving for hours
So, it will take the construction company 48 hours to remove 36 tons of dirt from the site.
