It's 78π inches so probably d.
Answer:
17.5
Step-by-step explanation:
The area for a triangle is (base*height)/2 this means
(5*7)/2 = 17.5 units^2
Answer:
38
Step-by-step explanation:
y(y+5)=84
y^2+5y-84=0
Δ=5^2-4*1*(-84)=25+336=361
VΔ=19
y1=(-5+19)/2=7
so P=2*7+2*(7+5)=14+2*12=14+24=38 cm
Answer:
41.14 pages per day
Step-by-step explanation:
Average number of pages read per day:
(Sum. Of the pages read pages read for the 7 days period) / Number of days
(40 + 30 + 35 + 49 + 56 + 34 + 44) / 7
= 288 / 7
= 41.142
= 41.14 pages per day
Answer: 684 divided by 57=12
Step-by-step explanation:(with reference to the figure)
To find 684 divided by 57 by partial quotients .
Here dividend= 684 and divisor =57
Step 1: Write easy factors of divisor that is nearest to the dividend as follows
57×2=114
57×3=171
57×5=285
57×10=570(nearest easy factor)
Step 2: Now subtract 570 from 684 ,we get 114 then subtract 114=57×2 from it we get 0.
Step 3: Adding the factors we have used in step 1 and 2 ,it will give required quotient=10+2=12
i.e. 684=57(10)+57(2)
