We know that
1 ft is equal to 12 in
12 1/2 ft------> (12*2+1)/2-----> 25/2 ft
3 ft 7 in
7 in------> 7/12 ft
so
3 ft 7in-----> 3 (7/12) ft----> (3*12+7)/12-----> 43/12 ft
<span>the small slide=(25/2)-(43/12)
</span>multiply (25/2) by 6/6-----> 150/12
so
the small slide=(25/2)-(43/12)----> 150/12-43/12----> 107/12 ft
the answer is
the small slide is 107/12 ft long
Answer:
64x
Step-by-step explanation:
because 4 * 2 is in parenthesis, that means you multiply 8x by them.
8x (4*2)
8x (8)
64x
Answer: No
Step-by-step explanation: If you plug in 10 for y and 2 for x, the equation becomes 10=9(2), which is 10=18.
The
correct answer is in file attached
<span>we have
triangle RSTm∠R = 60, m∠S = 80 and m∠T=180-(80+60)=40</span>
<span>RS=4
triangle EFDm∠F = 60, m∠D = 40 and m∠E=180-(60+40)=80</span>
EF=4
Therefore
<span>The triangles
RST and
EFD are
congruents because they have two angles and the side common to them,
respectively, equal.
This is the theorem of ASA (angle-side-angle).</span>
Explication
Side common--------> RS=EF
<span>Angles RS------------- > m∠R =
60 m∠S =
80 </span>
<span>Angles EF------------- > m∠E =
80 m∠F = 60 </span>
<span>Angles RS and Angles EF are equals</span>
<span>
The segment which is congruent
to RT is FD, because angles of RT are 60 and 40, and angles of FD also are 60
and 40.</span>
Answer:
100r^4 + 400r^3 + 600r^2 + 400r + 100
Step-by-step explanation:
Expanding ( r + 1 )^4 gives :-
r^4 + 4r^3 + 6r^2 + 4r + 1
So multiplying 100 with r^4 + 4r^3 + 6r^2 + 4r + 1 gives :-
100r^4 + 400r^3 + 600r^2 + 400r + 100
