Answer:

f(4) = 47

Step-by-step explanation:

f(x) = 12x - 1

Let x = 4

f(4) = 12(4) -1

Lucy fills a bathroom sink with water. Is the amount of water more than 1 liter, about 1 liter or less than 1 liter? Explain how
Novay_Z [31]
Proposed Answer
Much more than 1 liter.

Make a guess.
Suppose the bathroom sink is about 15 inches across. That's actually not very big for a bathroom sink. But it makes up for the other estimate I'm going to make. 

Suppose the sink is 7 1/2 inches deep at it's deepest point. So what you have is a 1/2 sphere. Figure this out in ccs. That way you have a simple conversion to make.

Conversion
1 in = 2.54 cm
7 1/2 in = x       Cross multiply

x * 1 inch= 7 1/2 * 2.54
x  =  6.5 * 2.54
x = 19.05 cm

x is actually the radius of the 1/2 sphere.
pi = 3.14
r = x = 19.05 cm

V = (4/3) pi * 19.05^3 / 2
V =  86831 / 6
V = 14471 ccs

1 L = 1000 cc
x  =    14471 cc

x = 14.471 Liters. That's 14.5 times bigger than 1 Liter. Most sinks are about 7 1/2 inches deep but they are more across than 15 inches. So my answer is much  more than 1 Liter.  <<<<< Answer

Answer much more than a liter.

Express the sum of (square root) -64 and 3(square root) -4 as a monomial in terms of I.

valentina_108 [34]

Answer:

MN=23

Step-by-step explanation:

For the midsegment:

MN=(WZ+XY)/2

10x+3=(11+8x+19)/2

10x+3=4x+15

6x=12

x=2

MN=10×2+3=23

The price of books are $180 but he uses a 30% discount but there is a 4% tax what is the total price?
Anna [14]

well, so the book is 180 and is discounted by 30%, how much will that be?

\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{30\% of 180}}{\left( \cfrac{30}{100} \right)180}\implies 54\qquad \qquad \underset{\textit{discounted price}}{\stackrel{180-54}{126}}

so from that discounted price, a tax of 4%

\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{4\% of 126}}{\left( \cfrac{4}{100} \right)126}\implies 5.04\qquad \qquad \underset{\textit{final price}}{\stackrel{126+5.04}{131.04}}
