Answer:
4 hours 21 minutes 17 seconds.
Step-by-step explanation:
1km = 6 minutes
42.195km = ?
42.195 × 6 = 253 minutes 17 seconds = 4 hours 21 minutes 17 seconds.
Answer:
4 hours 21 minutes 17 seconds.
Step-by-step explanation:
If you would like to know how many of each did Jan buy, you can calculate this using the following two equations:
b ... the number of books
m ... the number of magazines
$16 = b * $3 + m * $2.50 ... 16 = 3 * b + 2.50 * m
b + m = 6 ... b = 6 - m
__________________
16 = 3 * b + 2.50 * m
16 = 3 * (6 - m) + 2.50 * m
16 = 3 * 6 - 3 * m + 2.50 * m
16 - 18 = - 3 * m + 2.50 * m
- 2 = - 0.50 * m /0.50
m = 2 / 0.50
m = 4 magazines
b = 6 - m = 6 - 4 = 2 books
Result: Jan bought 4 magazines and 2 books.
Answer:
D (right-down graph)
Step-by-step explanation:
y = ax+b - linear function,
a>0 - ascending
a<0 - descending
- ascending function, because , so a>0
- descending function, cause , so a<0
We refuse both graphs on the left side, these are two ascending functions
is the area above the ascending function
is the area below the descending function
This causes that D (right-down graph) is a correct answer

Answer:
1. They are equal to 90°
2. They are both right angles so they are equal to 90° and they are on a straight line
3. An isosceles triangle has two sides of equal length
4. Right angles on a straight line
5. Isosceles triangle has two angles that are equal
