Answer:
Step-by-step explanation:
for the triangle:
1.9x8/2= 7.6mi (this is area)
perimeter=17mi
for the trapezoid:
area= 18.36+13.6=31.96yd
perimeter=24.1yd
Answer:
pairs of numbers is 3,-3
Step-by-step explanation:
The computation is shown below:
Let us assume a and b are the pairs of the numbers whose difference is 6
i.e.
a - b = 6
a = 6 + b
So
f = ab
f = (6 + b)b is minimum
Now
d ÷ db (6+ b)b = 0
(6+ b) + b = 0
2b = -6
b = -3
Now
a = 6 + b
= 3
So pairs of numbers is 3,-3
14a. =
15b. 2/3 is less than 0.667
16c. 3 7/8 is greater than 3.375
17d. 3/8 is less than 1/2
The equivalent ratios for 6:7 is 12:14 because 12/14 is equivalent to 6:7.The ratios for 14:28 is 1:2. The ratio for 27:9 is 3:1. The ratio for 15:12 is 5:4. Last but not least the ratio for 35:40 is 7:8.
