Answer:
<h2>34</h2><h2 />
Step-by-step explanation:
| 2 - 4a | - 2(b - 7)
let a = 3, b = -5
substitute a = 3, b = -5 into the equation:
| 2 - 4a | - 2(b - 7)
= | 2 - 4(3) | - 2(-5 - 7)
= | 2 - 12 | - 2(-12)
= | -10 | + 24
= 10 + 24
= 34
Answer:
Its 6.71
Step-by-step explanation:
Because using the formula, a^2+b^2=c2.
so it’s 3^2+6^2=6.71!
GOOD LUCK BOI OK
Answer:
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14
r2=257.5286624
Square root both sides to get radius
r=16 feet

Answer:
5 minutes to run 1 kilometer
Step-by-step explanation:
Alonzo takes 12 minutes to run 6 times around a 400-meter track.
6 times around a 400 m track
400 * 6 = 2400 meters
It take 12 minutes to run 2400 meters
2400 meters = 2400/1000 = 2.4km
distance = 2.4 km and time = 12 minutes
Now we find our constant speed
2.4 = speed * 12
divide by 12 on both sides
speed = 0.2
so speed is 0.2 km per minute
Now we find out time when distance = 1km
Distance = speed * time
1 = 0.2 * t
divide by 0.2 on both sides
5 = t
So it take 5 minutes to run 1 kilometer
Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot
