Using the Pythagoras theorem since it is given that it is a right angled triangle
let us name the triangle as A, B, C with B as right angle
AB^2 + BC^2 = AC^2 ( Pythagoras theorem)
where AB = 4 , BC = 7 , AC = x
Answer:
sum of ratio =3+2=5
David'share=£9900x3/5=£5940
Sum of ratio for part= 4+4+2=10
for himself=£5940x4/10=£2376
for wife=£5940x4/10=£2376
for son=£5940x2/10=£1188
his wife gets over son
£2376-£1188=£1188
Answer:
135 ft^2
Step-by-step explanation:
7yd = 7*3 feet = 21 feet
![area \: of \: trapezoid \\ = \frac{1}{2} (15 + 21) \times 7.5 \\ = \frac{1}{2} \times 36 \times 7.5 \\ = 18 \times 7.5 \\ = 135 {feet}^{2}](https://tex.z-dn.net/?f=area%20%5C%3A%20of%20%5C%3A%20trapezoid%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%2815%20%2B%2021%29%20%5Ctimes%207.5%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2036%20%5Ctimes%207.5%20%5C%5C%20%20%3D%2018%20%5Ctimes%207.5%20%5C%5C%20%20%3D%20135%20%7Bfeet%7D%5E%7B2%7D%20)
To find your answer you would divide 21 by 3 which would be 7, once you've got 7 you would multiply it by 9 which would give you the amount of old houses that there is which would be 63.
Answer:
5² = 25
Step-by-step explanation:
log5 25 = 2
log(b) (x) = (y)
make b^(y) = (x)
5² = 25
I hope this helps!
