Answer:

Step-by-step explanation:

To find the area of the shaded region, you have to start off with the area of the whole triangle. To find that, you multiply the height and length. length=10 height=8 (10x8=80). Then, since it's a triangle, you have to divide it by two (80/2=40). So, 40 is the area of the whole triangle. Then, you find the area of the white region, which is 12 (3x4=12). Finally, you take the area of the white square and subtract it from the area of the whole triangle (80-12=28). You would get 28.

What is a peregrine falcon's maximum speed while diving to catch prey,

Sergeu [11.5K]

This is an incomplete question, here is a complete question.

What is a peregrine falcon's maximum speed while diving to catch prey 200 miles per hour in feet per second? (Round your answer to the nearest whole number. (1 mile = 5280 feet)

Answer : The speed in feet per second is, 293 feet/s

Step-by-step explanation :

As we are given that the speed of peregrine falcon's is 200 miles per hour. Now we have to determine the speed in feet per second.

As we know that:

1 mile = 5280 feet

1 hour = 3600 second

So,

1 mile/hr = 1.4667 feet/s

As, 1 mile/hr = 1.4667 feet/s

So, 200 mile/hr = $\frac{200\text{ mile/hr}}{1\text{ mile/hr}}\times 1.4667\text{ feet/s}$

= 293.34 feet/s ≈ 293 feet/s

Therefore, the speed in feet per second is, 293 feet/s

.For a hockey game, tickets are $220 for

Romashka [77]

Answer:

900 front row seats

Step-by-step explanation:

Tickets for front row seat = 220 dollars (y)

Cost of remaining seats ticket = 50 dollars (z)

Number of front row seats = x

Number of remaining seats = 2050 (w)

Total amount earned when stadium is full = 300,500 dollars (T)

so if we formulate this using our variables y,z,x,w and T problem it becomes:

y*x + z*w = T, which says the

Tickets for front row seat times Number of front row seats plus Cost of remaining seats ticket times Number of remaining seats gives us Total amount earned by the stadium.

220*x + 2050*50 = 300500

220*x = 300500-102500

220*x = 198000

divide both side by 220

x = 900

Umnica [9.8K]

Answer: $x+y\geq12$

$2.75x+3.50y\leq35$

Step-by-step explanation:

Let x represents the number of red roses and y represents the number of white roses.

Given : Javier is purchasing a bouquet of roses from a floral shop. He wants the bouquet to have at least 12 roses.

i.e. the required inequality for this statement will be :-

No. of red roses +No. of white roses ≥ 12

i.e. $x+y\geq12$

Also, Red roses cost $2.75 each and white roses cost $3.50 each and he wants to spend less than $35.

i.e. $2.75(No. of red roses)+$3.50(No. of white roses)≤ $35

i.e. $2.75x+3.50y\leq35$

Now, From (1) and (2) the system of inequalities represents the situation :

$x+y\geq12$

$2.75x+3.50y\leq35$
