47.8 is 10% of?? what is the answer and how do I do it??

Answers

Answer 1

Answer: $1 \% = (1)/(100)\n \nx \cdot 10 \% = 47.8 \n \n x \cdot \not10^(1)\cdot (1)/(\not100^(10))=47.8\n \nx \cdot (1)/(10)=47.8 \ \ /*10 \n \n x \cdot (1)/(\not10^(1))\cdot \not10^(1)=47.8 \cdot 10 \n \nx =478$

Answer 2

Answer: very simple the answer is 478 to get there you know that 47.8 is 10% of something that something has to equal 100% so 10%x10= 100% 47.8x10=478

2x2 + 6x + 5 = 0 what are the real roots for the quadratic equation

Answers

$2x^2 + 6x + 5 = 0$

$x= (-b+/- √(b^2 -4ac) )/(2a)$

$x= (-(6)+/- √((6)^2 -4(2)(5)) )/(2(2))$

$x= (-6+/- √(36 -40) )/(4)$

$x= (-6+/- √(-4) )/(4)$

$x= (-6+/- i√(4) )/(4)$

$x= (-6+/- 2i )/(4)$

Find the area and perimeter of an isosceles trapezoid with legs 25cm and bases 16 cm and 30 cm.

Answers

Hi there, A=1/2(b1+b2)=1/2(h)(30+16). What we have to do is find h, 30-16=14/2=7, 25²-7²=625-49=576, we know that 576=24. So, h=24, 1/2(24)(30+16)=12(46). So, the area is 552 cm². Now, it's time to find the perimeter. P=b+b+l+l=30+16+25+25=96 cm. Therefore, the area is 552 cm² and the perimeter is 96 cm.

Leo is purchasing a bike that is on sale for 30% off. He knows the function that represents the sale price of his bike is c(p) = 0.7p, where p is the original price of the bike. He also knows he has to pay 12% sale's tax on the bike. The price of the bike with tax is f(c) = 1.12c, where c is the sale price of the bike.Determine the function that can be used to calculate the final price of Leo's bike by solving for f[c(p)].
f[c(p)] = 1.82cp
f[c(p)] = 1.82p
f[c(p)] = 0.784cp
f[c(p)] = 0.784p

Answers

f[c(p)] = (1.12)(0.7p) = 0.784p

A single function should have a single variable.

Answer: The answer would be f[c(p)] = (1.12)(0.7p) = 0.784p

Step-by-step explanation:

A single function should have a single variable.
