ACB + BAC =90
ACB + 37 = 90
ACB = 53
Tan (53) = 10/x
X= 7.536
(Hope this helped have a great day)
Answer:
17.5
Step-by-step explanation:
soln:
given,
since, x and y are directly proportional
and x=140, y=35
dividing x by y we get,
x/y=140/35
or,x/y=4/1
or,x=4y
when x=70,
x=4y
or,70=4y
•°•y=17.5
Answer:
Please check the explanation.
Step-by-step explanation:
<u>Determining equation B from Equation A</u>
Given the equation A
Apply distributive law 
which is equation B
Hence, equation B can be obtained by implementing the distributive law operation on equation A.
<u>Determining equation A from Equation B</u>
Given the equation B
Factor out common term -2 on the right-hand side of the equation
which is the equation A
Hence, equation A can be obtained by factoring out the common term -2 on the right-hand side of equation B.
We know that
the number of coins that each roll contains is
<span>rolls of quarters-------> 40 coins
</span><span>rolls of Dimes---------> 50 coins
</span><span>rolls of nickels------> 40 coins
</span><span>four rolls of quarters------> 4*40*$0.25-----> $40
</span>t<span>hree rolls of Dimes-----> 3*50*$0.10------> $15
</span><span>six rolls of nickels-------> 6*40*$0.05-----> $12
total=[40+15+12]------> $67
the answer is
$67</span>
