3.4 in words is: Three and four tenths
3.4 in expanded form 3+4/10
</span><span><u>Explanation</u>
Decimal points are fractions whose denominator is 10 or a power of 10. To write a decimal point in words we must be able to identify the place value of every digit.
3.4
3 is a whole number and its place value is ones and the place value of 4 is tenth.
So, 3.4 in words is: Three and four tenths
3.4 in expanded form 3+4/10</span></span>
Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
Answer:
Step-by-step explanation:
The mean for all students is
[102(68.5) + 85(72.4)] / (102 + 85) = (6,987 + 6,154) / 187 = 70.27272727...
So YES the class average was a pass, but just barely.
Answer:
(Option D)
Step-by-step explanation:
<u>GIVEN :-</u>
- Angle subtended by the arc at center (θ) = 90°
- Radius of the circle = 5 ft.
<u>TO FIND :-</u>
<u>GENERAL FORMULAE TO BE USED IN THIS QUESTION :-</u>
Lets say an arc subtends ∠θ at the center of the circle whose radius is 'r'.
<u>SOLUTION :-</u>
Length of the arc = 
Answer:
∠ 1 = 36° , ∠ 2 = 144°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles on a straight line and sum to 180° , that is
x + 12 + 6x = 180
7x + 12 = 180 ( subtract 12 from both sides )
7x = 168 ( divide both sides by 7 )
x = 24
Then
∠ 1 = x + 12 = 24 + 12 = 36°
∠ 2 = 6x = 6 × 24 = 144°
