456.89 would be 456.9 rounded to the nearest tenth.
Answer:
126
Step-by-step explanation:
The number of numbers divisible by 9 is ...
j = floor(500/9) = 55
The number of numbers divisible by 7 is ...
k = floor(500/7) = 71
Then the total (j+k) is ...
j +k = 55 +71 = 126
The first part of the answer can be found by finding the GCF between 15 and 25. 15 is divisible by 1, 3, 5, and 15. 25 is divisible by 1, 5, and 25. You can see that their GCF is 5. Next, you need to look at the variables. The first monomial has a, b, and

. The second monomial has

, b, and c. They each have at least one a, one b, and one c, so those will be in the GCF (abc). If you put that together with the 5, you get that the GCF is
5abc.
Answer:
(a)29
(b)91cm
(c)13cm
Step-by-step explanation:
(a)From the graph, 11 men have a waist measurement of 85cm and below.
Since the cumulative frequency is 40
Number of men who have a waist measurement of more than 85 cm

(b)Median

Tracing 20 from the y-axis to the x-axis, the median waist measurement is 91cm.
(c)Interquartile Range
Interquartile Range = 

From the graph, at y=10, x=84 cm

From the graph, at y=30, x=97 cm
Therefore:
Interquartile Range=97-84=13cm
Answer:
2.8 + 2x = 0.6
______
8
multiply by 8 to both sides
x8 x8
2.8 + 2x = 4.8
subtract 2.8 from both sides
-2.8 -2.8
2x = 2
divide by 2 from both sides
/2 /2
x = 1
