Answer:
24% of 33.50 = 80.40
67% of 87.99 = 58.96 (rounded up from 58.9533)
6% of 8.75 = 0.53 (rounded up from 0.525)
Step-by-step explanation:
to find the persentage of a number, you can first devide the whole number by 100, then multiply by the persentage ur figuring out, heres an example
for 24% of 33.50. we first devide 33.50 by 100
<em>33.50 / 100 = 3.35</em>
then multiply by 24
<em>3.35 * 24 = 80.40</em>
note if there are three numbers before the decimal point, and ur working with cash, always round up t the nearest hundredth
Answer:
(0.118, 4.882)
Step-by-step explanation:
If a motorist drives for m hours at 120km/hr, then the Distance of the motorist is expressed as;
Distance = Speed * time
da = 120m
If he drives n hours at 18km/hr;
db = 18 * n
db = 18n
Speed of the motorist altogether is expressed as;
Speed =78km/5hrs
Speed = 15.6km/hr
SInce the total distnce is 78km
120m + 18n = 78 ....1 ..... * 1
If total time is 5hrs
m + n = 5....2 ...*18
Solve simultaneously
120m + 18n = 78
18m + 18n = 90
Subtract
120m - 18m = 78-90
102m = -12
m = 0.118 hrs
m =
Since m + n = 5
n = 5 - m
= 5 - 12/102
n = 4.882
Hence (m,n) is (0.118, 4.882)
Answer:
sin R = 20 / 29
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin R = opp / hyp
sin R = 20 / 29
