Answer:
could u show me a picture of the assigment
Step-by-step explanation:
Answer: 58 minutes
55*4=220
62+57+43=162
220-162=58
First you need to find the circumference of the circle because 1 revolution is 1 length of the circumference. The formula for the circumference is C=2πr or C=πd, if the diameter is 1 meter then the circumference is π1 which is just π, and if it travelled 8000 rotations then that would mean it travelled 8000π, so it travelled 8000π in meters
Answer:
a; 3.45 * 10^3
b) 2.34 * 10^18
c) 80%
Step-by-step explanation:
a) 3450 in standard form
To write in standard form, we have to place a decimal at the back of the first non-zero number
we have this as ;
3.450
The count of numbers after the decimal point is 3
This will be the power to which 10 will be raised
We have this as;
3.45 * 10^3
b) 234 * 10^16
Let us write 234 in standard form
That will be;
234 = 2.34 * 10^2
So we have ;
2.34 * 10^2 * 10^16
Using the law of indices, we have;
2.34 * 10^(2 + 16) = 2.34 * 10^18
c) From the question, Kuwait is 4/5 of Hong kong’s population
Let Honk Kong’s population be x
4/5 * x = 2.4 million
4x = 5 * 2.4 million
x = 5 * 2.4/4
x = 5 * 0.6
x = 3 million
so writing the population of Kuwait as a percentage of that of Hong kong, we have
2.4/3 * 100%
= 0.8 * 100% = 80%
Answer:
C) m∠1 = 45°, m∠2 = 76°, m∠3 = 80°
Step-by-step explanation:
In the given figure. There are two triangles. We have to use the concept of the sum of interior angles of a triangle is 180°.
So,
m∠2 + 45° + 59° = 180
m∠2 + 104° = 180°
m∠2 = 180° -104°
m∠2 = 76°
m∠1 and 45° are the opposite angles. When two lines are intersection each there, then the opposite angles must be equal.
Therefore, m∠1 = 45°
m∠1 + m∠3 + 55° = 180
45° + m∠3 + 55° = 180°
m∠3 + 100° = 180°
m∠3 = 180° -100°
m∠3 = 80°
Therefore, m∠1 = 45°, m∠2 = 76°, m∠3 = 80°
Answer is C) m∠1 = 45°, m∠2 = 76°, m∠3 = 80°
