Answer:
64.
Step-by-step explanation:
There are 8 digits in the list.
This will be the number of permutations of 2 from 8 plus the duplicate numbers 11, 22 etc.
So we have 8P2 + 8 possibilities.
= 8! / (8-2)! + 8
= 56 + 8
= 64.
Step-by-step explanation:
Scale factor is found by making a fraction of two numbers;
In this case, 3.5/2, since the dilated line is larger
Scale factor: 1.75 (simplified)
Given that QYprime is 4.125,
4.125 * (2/3.5)
= 2.357 (rounded)
Answer:
5305.1647 times
Step-by-step explanation:
The Circumference of a circle : πd
d = diameter of circle = 30 cm
Circumference of wheel = π * 30cm = 94.247779 cm
1km to cm
1km = 100000cm
5 km = 500000 cm
Hence, number of times wheel rotate on a 5km journey :
500000 cm / 94.247779 cm
= 5305.1647 times
Answer:
Step-by-step explanation:
Given
Represent
3-point word with T;
2-point with U and
1-point with V
--- (1)
If total questions is 30, then
--- (2)
If total points is 55, then
--- (3)
Substitute 5 + V for U in (2) and (3)
--- (2)
---- (4)
--- (3)
Divide through by 3
---- (5)
Subtract (5) from (4)
Recall that:
Substitute 10 for V in (5)
