19.70-13=6.7
6.7/0.05=134
600+134=734
So in April she sent 734 text messages
Answer:
7.41
Step-by-step explanation:
Vertical component:
S = 268.8
U = 0
V =?
A = 9.8
T=?
S = ut + 0.5at^2. u = 0
268.8 = 0.5x9. 8xt^2
T = 7.41 seconds
A -5/8
B -15/24
because -30/48 divided twice will equal -15/24 which explains the second answer and -15/24 divided by three will equal -5/8
Answer:
464 feet
Step-by-step explanation:
<em>The Sine of the angle of inclination gives the increase in altitude.</em>
<em>This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e</em>
Sin Ф = Opposite ÷ Hypotenuse
Sin 5° = O ÷ 5328
0·08716 = O ÷ 5328
<em>Make </em>O<em> the subject and multiply every fraction by </em>5328
(0·08716/1 × 5328)= (O/5328 × 5328)
464·388 = O
∴ The increase in altitude is 464·388 feet
<em>This is supposed to be to the nearest foot so we round off</em>
464·388 becomes 464 feet
That is 6 * sqrt(2*8*3*6)
= 6 sqrt 16 * sqrt 18
= 6 *4 * sqrt 9 * sqrt2
= 6*4*3 sqrt2
= 72 sqrt 2
