Step-by-step explanation:

use herons formula

√s(s-a)(s-b)(s-c)

where s is the semi perimeter

S=20

and a,b,c are sides of triangle

=√20(20-17)(20-9)(20-14)

=√20.3.11.6

=62.92

nearest whole number is 63

Eva sees a dolphin 3.23.23, point, 2 meters below sea level and a bird \dfrac{47}{10} 10 47 ​ start fraction, 47, divided by, 10
soldi70 [24.7K]

Answer:

47/10 - 3.2

Step-by-step explanation:

Given

Dolphin = 3.2

Bird = 47/10

Required

What is the vertical distance between both

Using a vertical scale;

Represent the bird "above sea level" position with positive and dolphin at "below sea level" position with negative.

The vertical distance between them is as follows;

Distance = +[Above The Sea] - [Below The Sea]

Distance = +47/10 - 3.2

Distance = 47/10 - 3.2

Hence, the vertical distance between both is 47/10 - 3.2

a square flower garden in Samantha's backyard has an area of 100 square feet how much fencing will she need to enclose the flowe
Arlecino [84]
If Samantha's backyard has an area of 100 square feet, and you need to know how much fencing to enclose the garden, you know you are looking for the parameter of the garden. To fine the parameter you have to know the length of the sides. Area of a square is length times width and length and width are the same value. So what you know the square-root of 100 is the value of each side. So each side of the garden is 10 feet long. To find parameter all you do is add up all four sides. 10+10+10+10 = 40 feet need to enclose the flower garden.<span />

Laat month, andy collected 432 stamps, which was 4 times the number of stamps alva collected. If alva collected 6 times as many
Anastasy [175]
After Sally had given 1/9 of her stamps to Andy, she had 280 stamps (since they now have equal shares). So 280 was 8/9 of what she started with, making the 1/9 she handed over equal to 280/8, that’s 35. And Andy was “under” by the same amount she was “over” an equal share, that’s 35 under matching her 35 over, which is 70 altogether.

By all means use algebra but you may find you can reason a word problem through in words.
