If Susan can read 40 pages in 12 minutes, how many pages can she read in 50 minutes?
The key on a map says 2 inches equals 7 miles. If two cities are9 inches apart on the map, how far apart are they in real life?
Answer:
Ans(1) 167 (rounded off)
ans(2) 32 (rounded off)
Step-by-step explanation:
1. Pgs read in 12 mins= 40
Pgs read in 1 min= 40/12 =10/3
Pgs read in 50 mins= 10/3 ×50= 166.6
So, when rounded off, Susan can read 167 pgs in 50 mins./ (ans)
2. 2 inches distance= 7 miles
1 inch distance= 7/2 miles
9 inches distance= 7/2 × 9= 31.5
so, when rounded off, the cities are 36 miles apart in real life/ (ans)
Please help! I forgot how to do this.
Answer:
x = 35
Step-by-step explanation:
We can tell that these two angles are supplementary—that means that they add up to 180˚.
So, subtracting 75 from 180, we get 105. That's the value of angle 3x. Now, just divide 105 by 3. That's 35.
By that logic, x = 35.
