Answer:
132cm
Step-by-step explanation:
Split there firgue into shapes you know
there is a rectangle and a Trapezoid
A = bh
A = 7×4
A = 28cm
Trapezoid
A = 1/2h(b+b)
A = 1/2×8(19+7)
A = 1/2×8(26)
A = 1/2(208)
A = 104cm
Add them together
104 + 28 = 132
The correct answer is b. The domain of the function is in terms of x, so we are looking at the x-axis. The line stretches from 3 to 7 on the x-axis, so we know that b is our answer.
Answer:
BC < CE < BE < ED < BD
Step-by-step explanation:
In the triangle BCE,
m∠BEC + m∠BCE + m∠CBE = 180°
m∠BEC + 81° + 54° = 180°
m∠BEC = 180 - 135
m∠BEC = 45°
Order of the angles from least to greatest,
m∠BEC < m∠CBE > mBCE
Sides opposite to these sides will be in the same ratio,
BC < CE < BE ----------(1)
Now in ΔBED,
m∠BEC + m∠BED = 180°
m∠BED = 180 - 45
= 135°
Now, m∠BDE + m∠BED + DBE = 180°
11° + 135°+ m∠DBE = 180°
m∠DBE = 180 - 146
= 34°
Order of the angles from least to greatest will be,
∠BDE < ∠DBE < ∠BED
Sides opposite to these angles will be in the same order.
BE < ED < BD ----------(2)
From relation (1) and (2),
BC < CE < BE < ED < BD
Answer:
21 boxes of books
Step-by-step explanation:
guy= 140 lbs
each box= 40lbs elevator can only weigh up to 1010
i took 1010- 140 and got 870lbs left for the books
then i took 870 divided by 40 (to see how many boxes of books can be put on the elevator) and got 21.75
so 21 boxes could go on the elevator at a time
Answer:
The distance is 1.41 to nearest hundredth.
Step-by-step explanation:
The line y = x + 3 passes through the point (0, 3) on the yaxis.
Find the perpendicular line passing through this point:
y - 3 = -1(x + 0)
y = -x + 3
Now find the point where this line intersects the line y = x + 1:
y = -x + 3
y = x + 1
-x + 3 = x + 1
3 -1 = x + x
2x = 2
x = 1
and y = 2
So this point is (1, 2)
We require the distance between this point and (0, 3)
This = √((3-2)^2 + (0-1)^2) = √2
= 1.4142
