Answer:
From the information given
x is time for which she ran at speed of 6mi/h and
y is time for which she biked at speed of 12.5 mi/h
total time = 3.5 h
total distance = 34 mi
so
6x + 12.5y = 34 and
x + y = 3.5
x = 3.5 - y
6 ( 3.5 - y) + y = 34
6.5y = 13 which gives
y = 2 and this
x = 1.5
so suze ran for 1.5 h and biked for 2 h
CHECK
speed of run X time of run + speed of biking x time of biking must be = total distance covered
6 × 1.5 + 12.5 × 2 = 9 + 25= 34 mi
which is true
Answer:
6.3 ft
Step-by-step explanation:
The perimeter of a parallelogram is given by
P = 2(l+w)
49.6 = 2 (18.5 +t)
Divide by 2
49.6/2 = 2/2 (18.5 +t)
24.8 = 18.5+t
Subtract 18.5
24.8-18.5 = t
6.3 = t
If you add the two purchases, you find 9 hotdogs and 9 hamburgers cost 24.75. One hotdog and one hamburger will cost 1/9 of that total, or 2.75.
... One hotdog and one hamburger costs $2.75.
_____
This is what your question asks. Usually, we want to know the individual costs of the items. If we multiply this total by 5, then we have the cost of 5 hotdogs and 5 hamburgers: 13.75. This $1.75 more than the cost of 5 hotdogs and 4 hamburgers, so the cost of a hamburger must be $1.75
... One hotdog costs $1.00
... One hamburger costs $1.75
Answer:
The Answer to your problem is 3
√
2
Step-by-step explanation:
Step 1. Find 0 ( helps to plot z on complex plane)
z is in quadrant 4
0 is between -
/z and 0
Step 2. Find modulus |z|
|z|= check mark 3 to the power of 2 + (-3) power of 2 = check mark, 9+9 = check mark 18 =check mark 9.
Step 3. Write out z in polar form
z = 3 check mark 2.
1. acute
2. obtuse
3. right
4. (draw right angle)
5. (draw acute angle)
6. (draw obtuse angle)
7. (draw obtuse angle)
8. (draw obtuse angle)
9. (draw acute angle)
