approx 1 foot
The area (A) of a circle = πr² ( where r is the radius)
thus r² = A/π ⇒ r = √(A/π = √(3.21/π) =1.0108..... ≈ 1 foot ( to 1 dec. place)
Answer:
40°
Step-by-step explanation:
A parallelogram is a quadrilateral (a four-sided object) with parallel sides
Some of the characteristics of a parallelogram includes:
1. Opposite sides and angles are congruent.
2. Opposite angels are congruent
3. Consecutive angles are supplementary
4. The diagonals bisect each other
Angle DBC = ABD = 35 (alternate angles are equal)
Angle ADB = 180 - 35 - 105 = 40
I subtracted from 180 because sum of angles in a triangle is equal to 180
Answer:
She will have 12 sections per fabric and 36 sections in all
Step-by-step explanation:
Betty buy 3 fabrics of 30 ft²
If she cut each to 2/5 of 1 ft²
The she will have
30 × 2/5
= 6 × 2
= 12
She will have 12 for each fabric and for the 3 fabrics, she will have
12 × 3 = 36
Answer:
for the third problem a = cb
for the 4th problem x = 5a + g
for the 2nd problem p = (q - 3r) / 4
for the first problem x = (-9 - z) / y
for the last problem: b = 15
A = 1/2 bh
75 = 1/2 b(10)
75 = 1/2 10b
multiply both sides by 2
150 = 10b
divide by 10 from both sides
15 = b
b = 15
Speed used by Emily from home to post office is:
speed=(distance)/(time)
distance=3/4 miles
time=8:29:30-8:25=4 min 30 sec=4.5 min
thus speed=(0.75)/4.5=1/6 mile/min
The remaining distance from Post office to school:
3.42-0.75=2.67 miles
time taken to reach to school assuming that Emily will move with the same speed is:
time=2.67/(1/6)=16.02 min=16 min 1.2 seconds
time Emily will reach school is:
8:29:30+0:16:1.2
=8:45:31 a.m
This means that she will reach on time
