Please explain how you got the answer ​

For the total purchase, vera has been overcharged by $3. 50 for her purchase.

We have information that

3 orders at 0.89$

[tex]=3\times 0.89=2.67[/tex]$

12 orders for 0.15$

[tex]=12\times0.15=1.8[/tex]$

for 1 order 2.99$

[tex]=1\times 2.99=2.99[/tex]$

and also 8.69$ for a photo album

so total amount = 2.67+1.8+2.99+8.69= 16.15$

Now 7% of the tax =[tex]16.15\times1.07=17.2805[/tex]

Thus the difference of the amount =20.78-17.2805=3.5$

Thus the total purchase, vera has been overcharged by $3. 50 for her purchase.

Given:

using this formula:

[tex]\hookrightarrow \sf \pi r^2 + \pi rl[/tex]

The formula of a square pyramid is given as

[tex]A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\[/tex]

Let's substitute the values and solve for the area of the square pyramid.

[tex]A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\\\A = 3^2 + 2*3\sqrt{\frac{3^2}{4} + 3.63^2} \\A = 9 + 6{\sqrt{15.43} } \\A = 32.57ft^2[/tex]

Since the cost of 1 square foot  = Rs. 560

32.57 ft^2 = x

[tex]1sq = 560\\32.57 = x\\x = 32.57 * 560\\x = 18,239.2[/tex]

The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.

Answer:

X=12

Step-by-step explanation:

Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.

10X-20+6X+8=180 (collect like terms)

10X+6X=180-8+20

16X=192 (Divide both sides by 16)

X=12
