Answer:
Soccer: 19 Males
Basketball: 29 females
Total: 40 males, 60 females
Step-by-step explanation:
MALES FEMALES TOTAL
SOCCER ║ 19 ║ 31 ║ 50 ║
BASKETBALL║ 21 ║ 29 ║ 50 ║
TOTAL ║ 40 ║ 60 ║ 100 ║
[OPTIONS ⇒ 19, 29, 40, 60]
<u>SOCCER:</u>
x + 31 = 50
50 − 31 = 19
<em>19 males</em>
<em />
<u>BASKETBALL</u>
21 + y = 50
50 − 21 = 29
<em>29 females</em>
<em />
<u>TOTAL:</u>
F: 31 + 29 = 60
M: 19 + 21 = 40
60 + 40 = 100
<em>60 females </em>
<em>40 males</em>
Answer:

Step-by-step explanation:
Let's set up a proportion.

He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.
There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.

We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.


Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.




Rob can peel 5 oranges in 12 minutes.
Answer:
87.92
Step-by-step explanation:
3.14(a² + ab)
= 3.14 (4² + 4 × 3)
= 3.14 (16 + 12)
= 3.14 × 28
= 87.92

Answer:
Move everything so all terms are on one side of the = sign, and solve for zero using the Quadratic Formula. There are two answers: v=7±√69
10
Step-by-step explanation:
Subtract 1 from both sides so you have
e "standard form" of a quadratic is
, so first we have to identify a, b, and c in your equation: a=5, b= -7, and c= -1.
The quadratic formula is
. Plugging in your values, we get
−
. It looks a little funny, but you can't simplify it any more. You can check the answer by graphing the function on your calculator and asking for the function value at these points.
After graphing, hit 2nd, "Calc", "Value" on your TI, and type in either
, and you'll get that
