(5,25)(10,40)
slope = (40 - 25) / (10 - 5) = 15/5 = 3
y = mx + b
slope(m) = 3
(5,25)...x = 5 and y = 25
sub and find b, the y int
25 = 3(5) + b
25 = 15 + b
25 - 15 = b
10 = b
equation is : y = 3x + 10...sessions are $ 3 and the membership fee is $ 10
11.023 pounds, first divide 1 kg by 2.2 lbs and then multiply that number by the value you in pounds you are trying to convert.
Answer:
42
Step-by-step explanation:
A=33
2a2=3·3
2·42≈41.56922
(a)
The ratios of corresponding sides are equal
= 2 ← scale factor
hence w = 2 × 2.3 = 4.6 cm
(b)
The perimeters are linear and will also be proportional with a scale factor of 2
the areas are proportional with scale factor 2² = 4
That is the area of rectangle B is 4 times the area of rectangle A
In general
If 2 figures are similar then linear ratio of sides = k
Then the ratio of their areas is k²
and the ratio of their volumes is k³
4000+7000= 11,000 nearest thousands
4281+7028= 11,309 actual number
