Tom brought 7/8 gallons of water to a party and his friends drank2/3 of it. How many gallons of water did they drink?

natka813 [3]

In plain and short, what's 2/3 of 7/8? well, is just their product.

$\bf \cfrac{7}{8}\cdot \cfrac{2}{3}\implies \cfrac{7\cdot 2}{8\cdot 3}\implies \cfrac{14}{24}\implies \stackrel{simplified}{\cfrac{7}{12}}$

A dinner plate has a circumference of 106.76 cm. What is the area of the dinner plate? Use = 3.14.

Sphinxa [80]

C=2pr, r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2 (to nearest one-hundredth of a square cm)

The graph below shows three functions: Graph of function f of x equals 0.5 to the power x. Graph of function g of x is a line se

Phantasy [73]

Answer: f(x)= $0.5^x$ has all real value as its domain.

Explanation: since, we have three functions f(x)= $0.5^x$ ,

while g(x) and p(x) are line segments.

Now, g(x) is a function by a line segment which passes through two points (-1.8,-3) and ( 1,3.8).

Thus it is clear that its domain will be the ends points. so domain of the function g(x) will be [-1.8, 3.8] which is the subset of real numbers set (R).

Similarly, domain of function p(x) will be [1.7, 1], which is also the subset of R.

But, when we talk about f(x) it contains all the possible value of x. Thus we can say that $f(x)= 0.5^x$ has R as its domain.

A(\stackrel{x_1}{4}~,~\stackrel{y_1}{5})\qquad 
B(\stackrel{x_2}{1}~,~\stackrel{y_2}{2})\qquad \qquad 
% distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
AB=\sqrt{(1-4)^2+(2-5)^2}\implies AB=\sqrt{(-3)^2+(-3)^2}
\\\\\\
AB=\sqrt{9+9}\implies \boxed{AB=\sqrt{18}}\implies AB=\sqrt{2(9)}
\\\\\\
AB=\sqrt{2(3^2)}\implies \implies AB=3\sqrt{2}$
