Answer:
y = ± 15
Step-by-step explanation:
Given
y² = 225 ( take the square root of both sides )
= ± ![\sqrt{225}](https://tex.z-dn.net/?f=%5Csqrt%7B225%7D)
y = ± 15
That is y = 15, y = - 15
Since 15 × 15 = 225 and - 15 × - 15 = 225
Answer:
The width of the bathroom is 10ft.
Step-by-step explanation:
To find the area of a rectangle, we use the formula
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>area</em><em> </em><em>=</em><em> </em><em>width x length</em>
So we know that length is equal to 7 ft, and we also know the total area which is 70 sq.ft.
70 = ? x 7
multiplication and division are inverse operations, so we will divide instead
70 divided by 7 = 10
And we are done!!

Step-by-step explanation:
Answer:
Lin: distance per second*time or 8.2*25= 205m
Elena: distance total divided by time 250/28= 8.9m/s
Diego: time*rate of speed or -8.1*32 = -259.2 meters from the starting point.
Andre: total distance/time -285/35= a velocity of 8.1 meters per second
Step-by-step explanation:
Assuming that:
1
m
=
3.3
f
t
1m=3.3ft
We can make the conversion from feet per second to meters per second with this procedure:
(
165
f
t
s
)
(
1
m
3.3
f
t
)
=
50
m
s
(165
s
ft
)(
3.3 ft
1 m
)=50
s
m
Let
x
x be the amount of meters the parachutist will fall during 15 seconds of free fall
Having that in 1 second the parachutist falls 50 meters, we can calculate
x
x :
x
=
(
50
m
s
)
(
15
s
)
x=(50
s
m
)(15 s)
x=750 m
