Answer:
1.
a) 5cm
b) 16cm
c) 25cm
d) 124cm
2.
a) 4m
b) 6m
c) 10m
d) 26m
3.
a) 2km
b) 4km
c) 11km
d) 28km
Step-by-step explanation:
When you have a number and it tells you to round it to the nearest cm (m, km etc.), it means you just have to make it a whole number (integer) instead of a decimal by rounding it up or down.
To tell whether you round up or down, you look at the number after the decimal place and if it is under 5, you round down but if it is 5-9 you round up.
For example,
If we had 20.3 (not one of the questions) you would round it down to 20 because the 3 after the decimal place is smaller than 5.
However, if we had 24.7 you would have to round it up because the 7 is from 5-9.
Hope this helps :)
Answer:
The correct option is;
Segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A
Step-by-step explanation:
All chords perpendicular to the radius of a circle are bisected by the radius of the circle
Given that DA can be extended to the circumference of circle A to form a radius of the circle A, and that DA is perpendicular to EF, therefore, DA bisects EF or EF is bisected into two equal parts by DA such that segment ED is congruent to segment FD
Therefore, the correct option is that segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A.
The change in temperature is -28°F
So, Option D is correct.
Step-by-step explanation:
Temperature at day time = 72°F
Temperature at night = 44°F
What number represents the change in number?
Change in temperature = Temperature at night - Temperature at Day
Change in temperature = 44°F-75°F
Change in temperature = -28°F
The change in temperature is -28°F
So, Option D is correct.

Divide the number of guest that came by the number of guests invited: 104/125=.832 or 83%. 83% of the invited guests were there :)
So if you do 584/4 you get 146 which is the miles per hour, which is the rate of the jet. Also, the jet could fly 1,898 miles in 13 hours.
