Answer:
560 m
Step-by-step explanation:
Jill's distance is given as 250 m.
John's distance can be computed as ...
distance = speed × time = (70 m/min)(3 min) = 210 m
Suzy's distance is given as 100 m.
Then the total distance is ...
250 m + 210 m + 100 m = 560 m
The distance traveled is 560 m in this relay.
b. you add 6000 kilograms of water to the pool. what is the depth of the water in the pool? write your answer as a fraction. the water is about meters deep.
Answer:
1). Mass of water present= 18000 kg
2).4/3 meters deep
Step-by-step explanation:
Area of the rectangle= 6*3= 18m²
Volume of water in the pool
= Deepness of water*area of rectangle
= 1*18
= 18 m³
density of water is about 1 gram per cubic centimeter
In kg per m³= 1000 kg/me
Mass of water present= density*volume
Mass of water present= 1000*18
Mass of water present= 18000 kg
2)6000 kilograms of water is added to 18000 of
Total mass present= 6000+18000
Total mass present=24000 kg
If density= 1000kg/m³
Volume present= mass/density
Volume present= 24000/1000
Volume present= 24 m³
Area of the rectangle= 18 m²
deepness of the pool= volume/area
deepness of the pool= 24/18
deepness of the pool= 4/3 meters deep
Answer:
6:1
Step-by-step explanation:
48:( 4+4 )
= 48:8
= 6:1
Give your answers to 2 decimal places when appropriate
The roots of the equation 9x² - 29x - 28 = 0 are x = 4 and x = -0.78.
The equation given is a quadratic equation. To solve it, we can use the quadratic formula: x = [-b ± sqrt(b²-4ac)] / (2a), where a, b, and c are coefficients of the quadratic equation. In your equation, a=9, b=-29, and c=-28.
So now, we substitute these values into the quadratic formula:
x = [29 ± sqrt((-29)²-4*9*(-28))] / (2*9)
Solving inside the square root first, we get:
x = [29 ± sqrt(841+1008)] / 18
x = [29 ± sqrt(1849)] / 18
Continue to simplify and you get:
x = [29 ± 43] / 18, which gives us two possible solutions:
x = 72 / 18 = 4
and
x = -14 / 18 = -0.78 (to two decimal places).

Answer:
x = 4 or x = 0.78
Step-by-step explanation:
9x² – 29x – 28 = 0
2 roots: x = ((-(-29) ± √(-29)² - 4 x 9 x (-28)) / (2 x 9)
= (29 ± √841 + 1008) / 18
= (29 ± 43) /18
x = 72 /18 = 4 or
x = -14 /18 = - 0.78
