5 0

Answer:

1 and 3

Step-by-step explanation:

Step 1 is clearly elaborated.  Tax is impliedd on the discounted price.

In step 3, the steps of deductions are skipped.

Like 1 + 10% = 110% and 1 - 20% = 80%

Step 2 is simply wrong. Because the percentages are implied on different values.

The area of the trapezoid
ELEN [110]

Answer:

<h2>A = 82.5 in²</h2>

Step-by-step explanation:

The formula of an area of a trapezoid:

A=\dfrac{b_1+b_2}{2}\cdot h

b₁, b₂ - bases

h - height

We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:

A=\dfrac{10+5}{2}\cdot11=\dfrac{15}{2}\cdot11=7.5\cdot11=82.5\ in^2

How many solutions does this equation have?
Greeley [361]

Answer:

No solution

Explanation:

-4+19-7f = -15-7

cancel terms on both sides ( add 7f on both sides)

Calculate the sum

-4+19= -15

-4+19=15

15 = -15

The statement 15 = -15 is false so there is no solution :)

If the ratio of surface areas of 2 similar figures is 144/25 ; What is the ratio of their volumes?
kkurt [141]

Answer:

1728/ 125

Step-by-step explanation:

The ratio of corresponding lengths  of the figures = ratio of the square root of their areas.

So ratio of lengths =  12/5.

Now volume is 3 dimensional  so the ratio is the cube  of the lengths

= 12^3/5^3

= 1728/ 125.
