Answer:
The girls worked together on their art project for 1 hour and 50 minutes.
Step-by-step explanation:
In order to find the answer you have to find the difference between the time they began working and the tine they finished working. You have to subtract 3:25 from 5:15.
Since 25 minutes on the time they began working is higher than 15 minutes, you have to subtract 1 from the time they finished working that is 5 hours:
5-1=4
Then, you have to increase the minutes on the time they finished working by 60:
15+60=75
Now, you have to subtract the minutes which would be 25 from 75:
75-25=50
Finally, you have to subtract the hours which would be 4 minus 3:
4-3=1
The result would be 1 hour and 50 minutes.
According to this, the answer is that the girls worked together on their art project for 1 hour and 50 minutes.
Answer:
Chris have 24 local stamps
Step-by-step explanation:
We are given that The ratio of the number of local stamps to foreign stamps is 1 : 3.
Let the ratio be x
Number of local stamps = x
Number of foreign stamps = 3x
Total Number of stamps =x+3x=4x
We are given that Chris has 96 local and foreign stamps altogether in his collection
So, 4x=96
x=24
Hence Chris have 24 local stamps
Answer:
4. x = 6
5. x = 31
6. x = 34
Step-by-step explanation:
4. vertical angles
- 36/6 = 6
5. supplementary angles
180 - 56 = 124
124/4 = 31
6. complementary angle
90 - 22 = 68
68/2 = 34
1. move 78.2 over to the over side. This will give you 287-78.2.
2. when you have .5x = 208.8, divide both sides by .5
3. this should give you x= 417.6
4. make sure to check your work by plugging you answer back into x.
Answer:
The answer to your question is: a = 3.5 units
Step-by-step explanation:
Right triangle
to find a we need to use the trigonometric function cosine
cosine Ф = opposite leg / hypothenemus
Clear opposite leg from the equation
opposite leg = hypothenemus x cosine Ф
a = opposite leg = 5 x cosine 45
a = 5 x 0.70
a = 3.5 units
