You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m

A blueberry pie is shot out of a pie cannon from a height of 6m and with a velocity of 60 m/s. How many seconds will pass before
sveta [45]

Answer: 1.106 s

Step-by-step explanation:

This situation is related to projectile motion and one the equation that models the height of the blueberry pie in time is:

y=y_{o}+V_{o}sin(\theta) t-\frac{1}{2}gt^{2}

Where:

y=0 m is the blueberry pie final height (when it hits the ground)

y_{o}=6 m is the blueberry pie initial height

V_{o}=60 m/s is the blueberry pie initial velocity

\theta=0 \° is the angle, assuming the pie was shot horizontally

t is the time

g=9.8 m/s^{2} is the acceleration due gravity

Rewriting the equation:

0=y_{o}-\frac{1}{2}gt^{2}

Isolating t:

t=\sqrt{\frac{2y_{o}}{g}}

t=\sqrt{\frac{2(6 m)}{9.8 m/s^{2}}}

Finally:

t=1.106 s

How would you solve this?

Answer:the probability that a pensioner catches a flu is 0.3 or \frac{3}{10}

Step-by-step explanation:

<u>Data:</u>

a) Pensioners who have had a flu jab = \frac{3}{5}

b) Pensioners who did not had a flu jab = 1 - \frac{3}{5} = \frac{2}{5}

For the first pair of arrows: a is the probability of the upper arrow and b is the probability of the lower arrow.

<em>If pensioner have had a flu jab, the probability of catching flu is \frac{1}{30}</em>

Data:

c) Catching flu = \frac{1}{30}

d) Not catching flu = 1 - \frac{1}{30} = \frac{29}{30}

The second pair of arrows on the top: Top arrow is c and bottom arrow is d

<em>If pensioner did not have a flu jab, the probability of catching flu is \frac{7}{10}</em>

<u>Data:</u>

e) Catching flu = \frac{7}{10}

f) Not catching flu = 1 - \frac{7}{10} = \frac{3}{10}

The second pair of arrows on the bottom: Top arrow is e and bottom arrow is f.

Q) Probability pensioner catches a flu

P(catches the flu given that he had the flu jab) + P(catches the flu given that he did not have the flu jab)

(\frac{3}{5} x \frac{1}{30}) + (\frac{2}{5} x \frac{7}{10} )

= 0.02 + 0.28

= 0.3

Therefore, the probability that a pensioner catches a flu is 0.3 or \frac{3}{10}
