Answer:
y = 6.5 units
Step-by-step explanation:
Let L be the length of sides of the square.
Given the following data;
Perimeter of square = 8y - 12
Area of square = 100 square units
To find the value of y;
Area of a square = L²
Substituting into the formula, we have;
100 = L²
L = √100
L = 10 units
Mathematically, the perimeter of a square is given by the formula;
Perimeter of a square = 4L
Substituting into the formula, we have;
8y - 12 = 4*10
8y - 12 = 40
8y = 40 + 12
8y = 52
y = 52/8
y = 6.5 units
The ratio of group 1 to group 2 to total is 4:7:11.
4:7:11= x:y:33
11*3=33
Multiply the other numbers by 3 to get the answers for x and y.
x= 4*3=12
y= 7*3=21
Final answer: Group One-12, Group Two-21
Answer:
You CAN do it. triangle with the circle. find area of triangle first and subtract circle. (8*8)/2 = 32. minus circle. (2.5*pi^2) = 24.674011. so we have 32 - 24.7 (rounded) = 7.3 for triangle. as for the other? divide it into segments. we have a rectangle on bottom followed by 2 triangles on top of that rectangle. Recangle height is 2 * width. The width is 8 as we can see the top. 2*8= 16. plus the triangles. we know the triangle height is 6 minus the 2 from the rectangle height so 6-2=4 times the width which is the rectangle width minus the 6 from the middle divided by 2 because there are 2 triangles. 8-6=2/2 = 1. height * width = 4 divide by 2 = 2. that is the area of one triangle. but because there are 2 triangles multiply by 2. 2*2 = 4. 16+4=20 for the area of the second figure.
Step-by-step explanation:
Answer:
(-3,3)
Step-by-step explanation:
the second number is the y value and determines the up and down and so if you then subtract the 2 you went up it's (-3,3)
The measure of angle E is 70, but that is if angle D and F are the same
