<em>Complementary= 90 Degrees </em>
<em>Equation: x + x = 90 </em>
A = x
B = x + 32
<em>2x = 90 - 32 </em>
<em>2x = 58
</em>
<em>x = 29
</em>
<em>Angle A = 29 degrees
</em>
<em>Angle B = 61 degrees.</em>
Answer:
4.44
Step-by-step explanation:
15 - 1.68 = 13.32
13.32 / 3 = 4.44
Answer: Choice B) 3 years
--------------------------------------
Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3
It will take 3 years
Namely, how many times does 1/56 go into 7/8? well, let's check
Answer: 1 1/4 (1 whole and 1/4)
6 1/4 = 25/4
5 = 5/1
(25/4)/(5/1) = (25/4)*(1/5)
(25/4)*(1/5)
25/20
1 5/20 = 1 1/4
