Answer:
The answer is 36,900 because if you multiply 12,300 and 3, you'll get 12,300. But, it's not correct, then you have to divide 12,300 and 3, which will give you 4,100. hope this helps!
Answer:
15.56 ft
Step-by-step explanation:
The formula for the area of a triangle is
A = ½bh
This is an isosceles triangle, so b = h.
Substitute the value of h
A = ½b² = 121
Multiply each side by 2
b² = 242
Take the square root of each side of the equation.
b = √242 ≈15.56 ft
The length of the two equal sides of the triangle is approximately 15.56 ft.
<em>Check:
</em>
A = ½(15.56)² = ½× 242 = 121 ft²
Answer:
Jim's claim is correct
Step-by-step explanation:
Total survey=100 people
Morning exercise=35 people
Afternoon exercise=45 people
Night exercise=20 people
Morning exercise : Total survey
=35 : 100
Afternoon exercise : Total survey
=45 : 100
Night exercise : Total survey
=20 : 100
Jim's claim is correct because in finding the ratio, one has to relate it with the total people involved in the survey.
Tara's claim however seems to relate one variable with two other variables
Example:
35 : 55
Morning exercise : (morning exercise + night exercise)
35 : (35+20)
35 : 55
One of the other angles is 72. Vertically opposite angles are equal.
Two angles that are side by side on this arrangement are supplementary.
That means they are to 180
x + 72 = 180
x = 180 - 72
x = 108
Answer
the for angles are
72 + 72 + 108 + 108
