Answer:
<u><em>Corral 4</em></u>
Step-by-step explanation:
we need to divide the area of the corral by the Number of animals In order To know the dedicated space for each animal
Corral 1 :
(50×40)÷110 = 18.181818181818 < 20
Then it doesn’t meet the requirements.
Corral 2 :
(60×35)÷115 = 18.260869565217 < 20
Then it doesn’t meet the requirements
Corral 3 :
(55×45)÷125 = 19.8 < 20
Then it doesn’t meet the requirements
Corral 4 :
(65×40)÷130 = 20
Then It meets the requirements
Answer:
Around 11.9
Step-by-step explanation:
5.3n + 7.75 = 70.85
First subtract 7.75 on both sides.
5.3n = 63.1
Then divide both sides by 5.3
n=11.9 (I rounded to the nearest tenth.)
Answer:
x = 23
Step-by-step explanation:
2x -3 + 47 = 90
2x = 46
x = 23
Let x = the unknown angle
sine of an angle is measure of the opposite leg divided by the hypotenuse.
sin x = 10/21
To now solve for x, we so the inverse of sine.
sin⁻¹(10/21) = x
Plug this into your calculator.
x ≈ 28.44 degrees. This would round down to 28 degrees, option B is your answer.
24.75= 2.25y - 22.95
+22.95 +22.95
47.7 = 2.25y (division here)
2.25 2.25
Y=21.2
