Answer:

23/50 or 46%

Step-by-step explanation:

I just added red and purple out of the total(red+purple/total=11+12/50=23/50)

then I multiplied the fraction by 2 to get out of 100 for the percentage(23/50*2=46/100=46%)

NeTakaya

Answer:

512 student tickets.

Step-by-step explanation:

Let x be number of student tickets and y be number of adult tickets.

We have been given that at Friday's football game 1,294 tickets were sold. We can represent this information as:

x+y=1294...(1)

We are also told that each student ticket costs $5.00, and each adult ticket costs $8.00 and 1,294 tickets were sold for a total amount of $8,816. We can represent this information as:

5x+8y=8,816...(2)

From equation (1) we will get,

y=1294-x

Substituting this value in equation (2) we will get,

5x+8(1294-x)=8,816

5x+10352-8x=8,816

-3x+10352=8,816

-3x=8,816-10352

-3x=-1536

x=\frac{-1536}{-3}

x=512

Therefore, 512 student tickets were purchased at Fridays football game.

The height, h, in meters above the ground, of a projectile at any time, t, in seconds, after the launch is defined by the functi
Ivanshal [37]
The equation h(t) =-6t^2 + 15t + 2 <span>sets the parabola. You can find the parabola vertex as:
</span>
t_v= \frac{-b}{2a} =- \frac{15}{2\cdot (-6)} = \frac{15}{12}= \frac{5}{4}=1.25

then 

h( \frac{5}{4} )=-6\cdot  (\frac{5}{4} )^2+15\cdot \frac{5}{4} +2= \frac{91}{8} =11.375

This means that the maximum height is 11.375 m and <span>a projectilereaches this height at 1.25 seconds.</span><span /><span>
</span><span>
</span><span>The projectile initially launched at time t=0, so the initial height is h(0)=2 m</span>

HELPP PLEASEE! pleaseeeeee
vfiekz [6]

Answer:

a = 14 km

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh  where b is the base and h is the height

112.7 = 1/2 ( a) 16.1

112.7 = 8.05a

Divide each side by 8.05

112.7/8.05 = a

14 =a

a = 14 km
