Hey there!

Answer:\boxed{v>-6}

Explanation:

13+2v-8+6>-7

Let's start off by simplifying both sides of the inequality.

2v+11>-v-7

Now add v to both sides.

2v+11+v>-v-7+v\\3v+11>-7

Let's subtract 11 from both sides.

3v+11-11>-7-11\\3v>-18

We finally move onto our last step! Divide both sides by 3.

\frac{3v}{3}>\frac{-18}{3}\\v>-6

\boxed{v>-6}\text{ is your answer.}

Hope this helps!

Answer:

v > - 6

Step-by-step explanation:

13 + 2v - 8 + 6 > -7 - v (calculate the sum of difference)

= 11 + 2v>-7-v (move variable to the left-hand side and change its sign and move constant to the right-hand side and change its sign)

= 2v + v > - 7 - 11 (collect like items and calculate the difference)

= 3v>-18 (divide both sides of the inequality by 3)

=v > - 6

*in parentheses is written what to do to get the next number*

Megan’s TV had a base price of $189 and the sales tax was 6.88%. Over the next four years, the TV consumed an average of $0.06 o
Leni [432]

Answer:

Step-by-step explanation:

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00

4 years = 3×365 days + 366 days = 1461 days

cost of electricity = 1461 days × $0.06/day = $87.66

lifetime cost = purchase price + electricity + repairs

= $202.00 + $87.66 + 2·$29

= $347.66

what is the final amount of 17.50 that is put into a saving account with 4 annual interest rate compounded yearly for 25 years?
pickupchik [31]
To find the total amount, you will use the formula for finding compounded interest.  This means you will be paid interest on top of the interest you have earned each year.

A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years

A = 17.50(1 + 0.04)^25
A = $46.65

This person would have $46.65 after 25 years.

A. Write the formula for the area A of a trapezoid. Use b1 and b2 for the lengths of the bases, and use h for the height.
lesya692 [45]

Answer:

(a) The formula for the area A of a trapezoid

                 A = \frac{1}{2}(b_{1}+ b_{2})h

(b) Solve the formula for h

                 h = \frac{2A}{b_{1}+b_{2}}

(c) Find the height h of the trapezoid

     The height h of the trapezoid is 6 cm.

Step-by-step explanation:

(a) The formula for the area A of a trapezoid

As b₁, b₂ being the lengths of the bases and 'h' is the height.

So, the formula for the area A of a trapezoid

A = \frac{1}{2}(b_{1}+ b_{2})h

(b) Solve the formula for h

As the formula for the area A of a trapezoid is  

A = \frac{1}{2}(b_{1}+ b_{2})h

So, formula for height h of trapezoid

h = \frac{2A}{b_{1}+b_{2}}

(c) Using the new formula to find the height h of the trapezoid

Using  h = \frac{2A}{b_{1}+b_{2}} to find the height h of the trapezoid.

So,

h = \frac{2A}{b_{1}+b_{2}}

h = \frac{2(72)}{16+8} ∵b₁ = 16, b₂ = 8, A = 72cm²

h = \frac{144}{24}

h = 6 cm

So, h = 6 cm

Hence, The height h of the trapezoid will be 6 cm.
