Answer:
65
Step-by-step explanation:
The sum of the angles in a triangle is 180. In a right triangle, there is one 90 degree angle. If the second angle is 25, and 90+25+the last angle must add up to 180, simple math can find the value of the last angle.
180-90-25=65
Answer:
30%
Step-by-step explanation:
A percent can be found by dividing the part by the whole, or
part/whole
In this case, the part is the amount he spent on fruit. The whole is the total amount he spent.
amount spent on fruit/ total amount spent
He spent $18 on fruit, and $60 in total.
$18/ $60
Divide 18 by 60
18/60
0.3
Convert 0.3 to a decimal by multiplying by 100 or moving the deicaml place two spots to the right.
0.3*100=30
0.3--> 3.0 --> 30
30%
He spent 30% on fruit.
Answer:
4.6 hours
Step-by-step explanation:
we first need to calculate the total distance he covered and total time taken whole for the journey.
Distance= speed X time
time = Distance/speed
let the total distance be X. he covers 2/5 if the journey first.
2/5 = 0.4
Time = 0.4x/45 hours
the remaining journey is 3/5x
he covers 1/3 X 3/5= 0.2x
time taken = 0.2/90 X hours
the remaining distance = 100× 1.2 = 120km
we add 0.4x + 0.2x to get the fraction he had covered
0.6x.
the remaining distance was X - 0.6x = 0.4 X
thus 120 km represents 0.4x of the journey
we calculate now the value of X
0.4x = 120
X = 300km
Total time taken = 0.4x/45 + 0.2/90 + 1.2 hours
replace X to get time
2.7 hours + 0.7 hours + 1.2 hours
= 4.6 hours
Let x be the number of hours and Let y be the number of views.
x y
1 125
2 250
3 375
4 500
5 625
