Answer:
25
Step-by-step explanation:
b=4x+1 h=x+1 A=175
A=bh
Substitute: 175=(4x+1)(x+1)
Expand: 175=4x^2+5x+1
Subtract 175
4x^2+5x-174=0
Solve w/quadratic formula
(-5 <u>+</u> sqrt(25+2784))/8
Simplify: x=6 or -29/4
Distance is positive, so x=6
4x+1=4*6+1=25
Answer:
cot theta
Step-by-step explanation:
t = theta
csc t = 1/ sin t
cos t . csc t = cos t / sin t = cot t
Answer:
90ft
Step-by-step explanation:
43,560ft² = L × l
43,560ft² = 484ft × l
43,560ft² ÷ 484ft = l
l = 90ft
That's a huge one. I don't think that anyone will actually answer that.
Multiply 4.50 by 0.07
4.50*0.07 = 0.315
Then the sales tax is about $0.32.
You can also do it mentally. Moving the decimal point in 4.50 once to the left gives you 10% of the original amount, 0.45. Move it again to get 1% of the price, 0.045. Then multiply this by 7 to get 7%.
