Answer: the answer is true
Step-by-step explanation:
The square of an odd number:
We're to conjecture, not do algebra, apparently. 1²=1, 3²=9, 5²=25, 7²=49, ...
We conjecture the square of an odd number is odd.
The product of two evens and an odd:
Again, we'll run some examples.
(2)(2)(1)=4
(2)(4)(3)=24
(4)(6)(5) =120
(4)(8)(1)=32
Conjecture: The product of two evens and an odd is a multiple of 4
Counterexample: The product of two fractions is never an integer
How about
3/4 × 4/3 = 1
Solution :
We observe that :
But BA is the perpendicular.
From the center B and WX is a chord.
Therefore, TW = TX (perpendicular from the centre of a circle to a chord bisects it)
Consider Δ BTX,
∠BTX = 90° (BA ⊥ WX)
BT = XT (Δ BTX is isosceles)
Since the angles opposite to equal sides are equal of a triangle arc are equal.
∠BTX = ∠BXT
But in the triangle,
∠TBX + ∠TXB + ∠BTX = 180°
∠TBX + ∠TBX + 90° = 180°
2 ∠TBX = 90°
∠TBX = 45°
From trigonometry, we get
...............(1)
WX = 10
i.e., TX + TW = 10
But TX = TW
2 TX = 10
Tx = 5
BX = radius of circle.
∴ 
= 7
Therefore, the radius of the circle is 7 units.
Answer:
.76 meters
Step-by-step explanation:
The area of a circle is pi*r^2
3.14*.85^2 = 2.26865
Dividing this into thirds gives us approximately .75621666666
Round to the nearest hundredth.
.76
Label the answer.
.76 meters
Answer:
6/24=x/100
Step-by-step explanation:
Computation for the equation that could be used to find x, the percent of lemonade in the whole recipe
The EQUATION to find x, the percent of lemonade in the whole recipe will be :
6 /24=x/100
Hence, cross multiply
x=6/24×100
x=0.25×100
x=25%
Therefore the equation to find x, the percent of lemonade in the whole recipe will be 6/24=x/100 which will give us x= 25% when will cross multiply.
