You are shipping a care package to your sister in college. It costs $0.85 per pound plus a flat-fee of $12 to ship the package.

Write and use an algebraic expression to find the total cost of shipping a 7 pound care package.

The expression should be
.85x+12=c. (C=cost, x=package in lbs)
And it would cost $17.95
.85(7)+12=
5.95+12=17.95

At a hot dog stand , they serve regular and footlong hot dog at a ratio of 3 to 2 . How many footlongs will be served if there i

garik1379 [7]

Answer:

32 Foot long hot dogs

Step-by-step explanation:

A hot dog stand serves 3 regular hot dogs for every 2 foot long hot dogs. This means they sell 3+2 = 5 together.

If they sell 80 in one day, then you find how many of each by solving the equation 5x = 80.

5x = 80

x = 16.

So 3*16 is the number of regular which is 48.

So 2*16 is the number of foot long which is 32.

If you roll two number cubes, what is the probability of their sum being 9 or higher?

aalyn [17]

Answer:

$Pe = \frac{10}{36}$

Step-by-step explanation:

Well, a standard cube number (dice) has numbers from 1 to 6. So the combinations that give 9 or higher, are 3-6, 6-3, 4-5, 5-4, 4-6, 6-4,5-6, 6-5, 5-5, 6-6. We will call this favorable cases (Fc) = 10

Yet, the total number of cases (T) is 6 different number by 6 different combinations (1-1 , 1-2 , 1-3 ..... 6-6), 6 x 6= 36 = T.

So, in order to calculate the probability of an event (10/36), you can use the following formula:

$Pe = \frac{Fc}{T}$

$Pe = \frac{10}{36} = 0.2777$

Cassidy wrote the linear equation y=5x+4 Then, she wrote the equation of the line that is parallel to y=5x+4 and that passes thr

Daniel [21]

Well, again <span>y=5x+4 is in slope-intercept form, therefore </span> $\bf y=\stackrel{slope}{5}x+4$ .

so then, a parallel line to a line with that equation, will also have the same slope, therefore, what's the equation of a line whose slope is 5 and goes through 8, -2?

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{8}}\quad ,&{{ -2}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 5
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-2)=5(x-8)\implies y+2=5x-40
\\\\\\
y=5x-40-2\implies y=5x-42$

Use the unit circle to find the value of tan 30

Harlamova29_29 [7]

Answer:

$\frac{\sqrt{3}}{3}$

Explanation:

$\sin(30^{\circ}) = \frac{1 }{2 }$

$\cos(30^{\circ}) = \frac{\sqrt{3} }{2 }$

$\tan(30^{\circ}) = \frac{\text{opposite} }{\text{adjacent} }$

$\tan(30^{\circ}) = \frac{\frac{1 }{2 }} {\frac{\sqrt{3} }{ 2}}$

$\tan(30^{\circ}) = \frac{1 }{2 } \times{\frac{2}{\sqrt{3} }}$

$\tan(30^{\circ}) = \frac{1}{\sqrt{3}}$

$\tan(30^{\circ}) = \frac{\sqrt{3}}{3}$
