859.
<span>Because it rounds to 900, it must be somewhere between 850-899. The fifth odd number you count beginning with 1 is 9 (1, 3, 5, 7, 9). That leaves 859, 869, 879, 889, and 899. Then use a calculator to add them up, and 859 is the only one that adds up to 22.</span>
Answer:
x=8+2√3 or x=8−2√3
Step-by-step explanation:
Let's solve your equation step-by-step.
9x2−16x+52=8x2
Step 1: Subtract 8x^2 from both sides.
9x2−16x+52−8x2=8x2−8x2
x2−16x+52=0
For this equation: a=1, b=-16, c=52
1x2+−16x+52=0
Step 2: Use quadratic formula with a=1, b=-16, c=52.
x=
−b±√b2−4ac
2a
x=
−(−16)±√(−16)2−4(1)(52)
2(1)
x=
16±√48

x=8+2√3 or x=8−2√3
Answer:
25 minutes
Step-by-step explanation:
Worker1 is filling up at a rate of 11 per minute while worker2 is filling up at a rate of 11+1 per minute. Since worker1 has 25 extra barrels and since worker2 makes one extra barrel per minute it will take exactly 25 minutes to match worker1's barrel count.
