Juan’s lunch would have costed less if he paid separately. his lunch is 5.25
the bill 37.20
37.20 / 5
$7.44 each kid
7.44 - 5.25 = 2.19
$2.19 less if he paid separately

Triangle ABC

Virty [35]

Answer:

15 cm

Step-by-step explanation:

Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.

A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

$\frac{BC}{EF} =\frac{AC}{DF}$ .

$\frac{18}{x}=\frac{12}{10}$

To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

$\frac{18}{x}=\frac{12}{10}\\ 18*10 = x*12 \\ 180 = 12x \\ 15 = x$

A. Find y in terms of x if ????y????x=x6y−7 and y(0)=4. y(x)= (8/7x^7+4^8)^(1/8) . B. For what x-interval is the solution define

topjm [15]

Answer:

Step-by-step explanation:

part A)

given

$x=x6y-7$

so y in terms of x would be

$y=(x+7)/x6$

part b)

in order to find intervals of function, we determine the intervals where the function has a positive first derivative . To find intervals, first we find the critical values, or points at which the first derivative of the function is equal to zero. For the given function the intervals would be

put zero in equation

$y=(x+7)/6x$

$y= infinity$

put 1

$y=1.333$

put 2

$y= 0.75$

put 3

$y= 0.555$

hence we can see that the interval is from zero to positive infinity

Express 12/7 as a mixed number

Sliva [168]

Answer:

1 5/7

Step-by-step explanation:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
