Answer:

48 hats and 104 shirts

Step-by-step explanation:

These are the equations you build from the problem:

h + s = 152

8.50h + 12s = 1656

This is how I solved them:

s= 152-h

8.5h + 12(152-h) = 1656

8.5h + 1824 - 12h = 1656

Solve for h

h= 48

Put this into first equation (h +s = 152) to get s

Answer:

B-One equation represents the total number of items sold, equaling the sum of the variables.

C-One equation represents the total revenue using the price of each item as a rate.

E-One variable represents the total hats sold and the other represents the total t-shirts sold.

Hope this helps.

Answer:

$4,224.53

Step-by-step explanation:

We begin by converting the problem into a linear equation

x = 3981.22 + 87 + 0.012x +0.025x...where x represents her gross monthly income

x = 4068.22 + 0.037x

x - 0.037x = 4068.22

0.963x = 4068.22

x = 4068.22/0.963

x = $4,224.53

The length of the shadow of a pole on level ground increases by 90m when the angle of elevation of the sun changes from 58° to 3

viva [34]

Answer:

119.45 m

Step-by-step explanation:

Given:

When angle of elevation of the sun changes from 58° to 36° the length of shadow of a pole increases by 90 m.

To find:

Length of pole = ?

Solution:

Kindly refer to the attached image.

$\triangle ABC$ represents the 1st angle of elevation of sun i.e. 58°

$\triangle ABD$ represents the 2nd angle of elevation of sun i.e. 36°

Change in shadow is represented by CD = 90 m

Let height of pole, AB = $h$ m

Let side BC = $x$ m

Now, let us apply tangent rules in $\triangle ABC, \triangle ABD$ one by one:

$tan\theta = \dfrac{Perpendicular}{Base}\\\Rightarrow tan58^\circ=\dfrac{AB}{BC}\\\Rightarrow tan58^\circ=\dfrac{h}{x}\\\Rightarrow x = 0.624h ..... (1)$

$tan36^\circ = \dfrac{h}{x+90}$

Putting value of $x$ using equation (1):

$tan36^\circ = \dfrac{h}{0.624h+90}\\\Rightarrow 0.726\times 0.624h+0.726\times 90 = h\\\Rightarrow h-0.453h =65.34\\\Rightarrow \bold{h = 119.45\ m}$

119.45 m is the height of pole.

Veseljchak [2.6K]

1/10 of 2000 is 200 pounds. so 200 pounds of cheese

i guess you mean 100 times more lettuce than beef so that would be 200,000 pounds of lettuce

200+200,000=200,200 final answer
