Area of a circle = pi*r^2, where r is the radius.
r = diameter/2
= 3.102/2
= 1.551
A = pi*1.551^2
= 7.557 cm^2
25/100= 1/4 , divide by 25 for the numerator and denominator
10/40= 1/4, divide by 10 for the numerator and denominator
7/28= 1/4, divide by 7 for the numerator and denominator
Answers:
25/100, 10/40, 7/28

By AAS test Postulate. Δ ABD ≅ Δ CDB
Step-by-step explanation:
Given:
∠ A ≅ ∠ C
AB || DC
To Prove:
Δ ABD ≅ Δ CDB
Proof:
In Δ ABD and Δ CDB
1. ∠ A ≅ ∠ C ……….{GIVEN}
2. ∠ ABD ≅ ∠ CDB …{if lines are parallel then alternate interior angle are equal}
3. BD ≅ BD ……….{ Reflexive property }
4. Δ ABD ≅ Δ CDB ….{Angle-Angle-Side test}
Answer:
x = -3
y = 4
Step-by-step explanation:
7x + 2y = -13
-7x + y = 25
3y = 12
-7x + y = 25
y = 4
-7x + 4 = 25
y = 4
-7x = 21
y = 4
x = -3
there is only 1 solution for this equation is (-3,4)
Hello!
To find the midpoint, use the formula:
.
Before using the formula, you must assign ordered pairs to x1, y1 and x2, y2. For this problem, (-4, 4) can be (x1, y1) and (5, -1) is (x2, y2).
.
Therefore, the midpoint of (-4, 4) and (5, -1) is (1/2, 3/2).
