Answer:
19.24 cm
Step-by-step explanation:
Square the outsides of the triangle. 8 squared is 64 and 5 squared is 25.
A^2+B^2=C^2
c^2 is always the diagonal line.
a^2=25
c^2=64
Subtract 25 from 64 to find b^2
64-25= 39
Add all three together to get your perimeter.
The square root of 64 is 8, the square root of 25 is 5 and the square root of 39 is 6.24. Add 8, 5 and 6.24 together and you get the perimeter.
5+8+6.24= 19.24
Answer:
x = 3
Step-by-step explanation:
12x = 36
simply 12 will go to the other side and switches to the opposite sign for example + will be -
× will br ÷
so 36 ÷ 12 =3
x = 3
Answer:
Step-by-step explanation:
The sides of a parallelogram are equal. If O is the midpoint of its diagonal AC, them AO+OC = AC
Given
AO = 4x + 12 and
OC = 5x – 6
Required
AC
AC = 4x+12 + 5x-6
AC = 4x+5x+12-6
AC = 9x+6
Hence the length of AC is 9x+6
Answer:
1. 125,000
3 17.5
4. 15
5. 17.5
Step-by-step explanation:
1. Create a unit rate. 20,000/8 = 2,500 straws per hour. This means in 50 hours multiply 2500*50 = 125,000.
3. Mean is the average and is found by adding all the date points and dividing by the number of them.
15 + 16 + 17 + 23 + 1 1+ 19 + 20 + 15 + 18 + 22 + 15 + 19 = 210
210 / 12 = 17.5
4. The mode is the number that occurs most often. Write the numbers in order and choose the one that happens the most.
11, 15, 15, 15, 16, 17, 18, 19, 19, 20, 22, 23
15 is the mode
5. The median is the number in the middle. If two numbers then take the average. The numbers in the middle when written in order are 17 and 18. So the 17+18 / 2= 17.5
