Answer:
8790 / 6=1465
Step-by-step explanation:
From this question we know that there are a total of 8790 fish, with 6 of them being kept in one tank, and we want to know how many tanks there are. So we do 8790 / 6 which gives us 1465.
Answer:
Area of the flower garden = 31.75 square meters
Step-by-step explanation:
Circumference of the circle shaped flower garden = 20 meters
Now, The circumference of circle = 2π × radius
⇒ 2π × radius = 20
⇒ π × radius = 10
⇒ radius = 3.18 meters
Area of the flower garden = π × radius²
⇒ Area of the flower garden = 3.14 × 3.18²
⇒ Area of the flower garden = 31.75 square meters
Answer:
1.27
Step-by-step explanation:
When completing word problems, it's always important to first turn everything into an equation.
The volume of a rectangular box is:
Where <em>l</em> is the length, <em>h</em> is the height, and <em>w</em> is the width.
Which we can write down the equation:
Next up, distribute:
We have a cubic equation, you can solve it using a calculator.
We have three solutions, and they are:
Since lengths cannot be negative, there is just one solution:
And rounding it gives:
And don't forget to put ft at the end!
Answer:
it takes 1st person 4 hour and second person is 8 hours
Step-by-step explanation:
Let t is the time (t >0)
We have:
- 1st person working rate per one task: 1/t-8
- 2nd person working rate per one task: 1/t
- Working rate per one task from 2 person: 1/3
<=> 1/3 = 1/t + 1/t-8
<=>
<=>
<=> t - 7 = 5
<=> t = 12
So it takes 1st person 4 hour and second person is 8 hours
Answer:
Step-by-step explanation:
The area of a trapezoid is the average of the parallel bases times the height or distance between the two bases
A=h(b1+b2)/2
Here we have h=8cm, b1=6cm, and b2=11cm so
A=8(6+11)/2
A=8(17)/2
A=4(17)
A=68 cm^2
