Answer:
The area of the triangle is : 201.5 cm ²
All the sides of an equilateral triangle are equal. A triangle has 3 sides. If the perimeter is 78cm, 78 cm needs to be divided by 3 so find each side of the triangle.
78÷3=26
In order to find the area of a triangle, you need to multiply the base by the height and divide the product by 2.
26×15.5=403
403÷2= 201.5
So therefore, The area of the triangle is : 201.5 cm ²
Answer:
5
Step-by-step explanation:
25/cooler and there are 2 coolers, 25*2=50 there are 10 friends so 50/10=5
Answer:
The answer is 0.664 because you have to divide 4/5 and 5/6
Step-by-step explanation:
Answer: there would be 52 yellow marbles
Step-by-step explanation:
Ok we know that there is 65 marbles in total? Right? So then we’d take 65 and think, what could we divide this by and start guessing and estimating numbers. (I guessed 5, one because it’s divisible by 65, two there is 5 times more yellow marbles than red marbles.) So 5 divided by 65 is 13. But, in order to find the amount of yellow marbles, we need to subtract the whole number by the amount of red marbles. (So 65-13 =?) if you subtract that you get 52 yellow marbles. :)
{x^2+y^2=36}
A.)(-6,0)
B.)(-2,4)
C.)(0,-6)
D.)(4,-2)
Answer:
(-6, 0)
Step-by-step explanation:
Check out A): (-6,0). This satisfies 2y-2x=12: 2(0) - 2(-6) = 12, and also satisfies x^2+y^2=36: (-6)^2 + 0^2 = 36. (-6, 0) is therefore a solution of the given system.
