Answer:
The correct answer is A or C 0.05n < 0.45
Step-by-step explanation:
Nickels cost $0.05 and n is the number of nickels, so you multiply the two to get 0.05n. Since this value is less than $0.45, we put a less than sign.
Answer: There were 168 automobiles parked in the garage
Step-by-step explanation: Let us assume the number of Non-suvs is 100. That means the number of SUVs would be equal to 100 + 40.
In other words, the number of SUVs would be 40% greater. To find the number of Non-SUVs would simply be to calculate backwards; 140 divided by 140%, that is
140 ÷ 1.4
140/1.4 = 100
Now, if the number of SUVs is given as 98, then the number of Non-SUVs is derived as
Non-SUVs= 98/140%
= 98/1.4
= 70
So we have 98 SUVs and 70 Non-SUVs.
Total number of automobiles parked is 168
Answer:
Step-by-step explanation:
It is given that in △ABC, ∠ABC=90°, BH is an altitude and AB=9 and AC=12, thus using the Pythagoras theorem in △ABC, we get
Now, From ΔABC and ΔHBC, we have
∠ABC=∠BHC(each90)
∠ACB=∠HCB (Common)
By AA similarity, ΔABC is similar to ΔHBC.
Thus, using the similarity condition, we get
