Answer:
70
Step-by-step explanation:
Using the similarity theorem;
AB/BC = AD/AB
x/7+3 = 7/x
x/10 = 7/x
x^2 = 70
x = √70
Hence the required value inside square root is 70
The correct answer is the last one.
1. Area of a circle is pi x R^2
Area = 3.14 x 18^2
Area = 3.14 x 324= 1017.36 sq. In.
The blade covers 122 out of 360 degrees.
1017.36 x 122/360 = 345 square inches.
2.
Like above.
Area =3.14 x 75^2 = 17,662.5 square feet
17662.5 x 80/360 = 3,925 square feet.
6.4x10^5 + 0.36x10^5 = 6.76x10^5, or 676,000
Here is your answer:
7.48+x=2.44+x 7.48 + x + -1x = 2.44 + x + -1x
x + -1x = 0
7.48 + 0 = 2.44 + x + -1x
7.48 = 2.44 + x + -1x
x + -1x = 0
7.48 = 2.44 + 0
7.48 = 2.44
7.48 = 2.44
Which would mean that this equation has "no solutions" or the first option.
Hope this helps!
