Answer:
0.012t + 28 = 30
Step-by-step explanation:
The depth starts at 28 meters. The amount of increase in t minutes will be 0.012t, so the total depth after t minutes is ...
0.012t +28
We want to find when that is equal to 30, so the appropriate equation is ...
0.012t +28 = 30
A
because it has used multiplicative property
Answer:
Area of kite = 190.44 m² Option C is correct.
Step-by-step explanation:
Area of kite = diagonal 1 * diagonal 2 /2
Here diagonal 1 = 9.2 + 9.2= 18.4 m
and diagonal 2= 6.9 + 13.8 = 20.7 m
Area of kite = 18.4 * 20.7 /2
Area of kite = 190.44 m²
As area of kite is 190.44 m² so, Option C is correct

The denominator cannot equal zero.
7 - 8x ≠ 0
7 ≠ 8x

is not in the domain
Answer:
a = 4.6
b = 4.2
Step-by-step explanation:
to find a, use cos:
⇒ cos = 
⇒ cos 30 = 
cos of 30 is 0.154
⇒ 0.154 =
multiply 13 on both sides:
⇒ 0.154 x 13 =
x 13
⇒ 4.62 = a
round to the nearest tenth:
⇒ 4.62 = 4.6
⇒ a = 4.6
to find b, use tan:
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 0.320
⇒ 0.320 = 
multiply 13 on both sides:
⇒ 0.320 x 13 =
x 13
⇒ 4.16 = b
round to the nearest tenth:
⇒ 4.16 = 4.2
⇒ b = 4.2
