Answer:

$284.80

Step-by-step explanation:

You multiply how long she worked, 32 hours, by the amount of money she makes per hour, $8.90, to get a total of $248.80.

Hello!

You can solve this algebraically

p + n = 115

p + 4.25n = 358.75

Subtract the two equations to eliminate p

-3.25n = -243.75

Divide both sides by -3.25

n = 75

Put n into the first equation

p + 75 = 115

Subtract 75 from both sides

p = 40

The answers are,

40 pounds of peanuts were sold
75 pounds of pecans were sold

Hope this helps!

Graph the function g(x) = 1/3-4/3x

mafiozo [28]

$g(x) = \frac{1}{3}- \frac{4}{3}x \\\\g(x) = - \frac{4}{3}x +\frac{1}{3}\\\\x=-5\ \ \to\ \ g(x)= - \frac{4}{3}*(-5) +\frac{1}{3}= \frac{20}{3} +\frac{1}{3}=\frac{21}{3}=7\\(-5,7)$

$x=7\ \ \to\ \ g(x)= - \frac{4}{3}*7 +\frac{1}{3}= - \frac{ 28}{3} +\frac{1}{3}=-\frac{27}{3}=-9\\(7,-9)$

Answer:

$\text{a. }128\:\mathrm{cm^3},\\\text{b. }4:1,\\\text{c. }179.4\:\mathrm{cm^2};\:44.8\:\mathrm{cm^2}$

Step-by-step explanation:

The volume of a square pyramid is given by $V=\frac{1}{3}\cdot s^2\cdot h$

Since pyramids A and B are similar, their corresponding side lengths are proportion. Since the base edge of B is half that of A's, each dimension of B will be half of A. Since the formula for volume requires the multiplication of three dimensions, the volume of pyramid A will be $2^3=8$ times larger than the volume of pyramid B.

Thus, the volume of pyramid A is equal to $16\cdot 8=\boxed{128\:\mathrm{in^3}}$ . You can also find the dimensions of pyramid A and use the formula.

The surface area consists of the sum of all areas of the 2D shapes that make the figure. Since all dimensions of pyramid A are twice the dimensions of pyramid B, the ratio of the surface area of pyramid A to pyramid B is $2^2:1=\boxed{4:1}$

The surface area of a square pyramid can be found by adding the areas of the three triangles and one square that make it up. As one long messy formula, that becomes $2s\sqrt{\left(\frac{s}{2}\right)^2+h^2}+s^2$ for a square pyramid with base edge $s$ and height $h$ .

Plugging in values, we get the following:

$A_a\approx \boxed{179.4\:\mathrm{cm^2}},\\A_b\approx \boxed{44.8\:\mathrm{cm^2}}$
