ased. Mr. Porter writes the equation below to express the current value of his house. d+0.21d=1.21d d+0.21d=1.21d Mr. Porter claims that the value of his house has increased by 121% 121%, since 1.21 is equal to 121% 121%. Decide if Mr. Porter is correct. If he is correct, enter 121 below. If he is not correct, enter the correct percent increase.

Answer:

Mr. Porter's claim was not correct and it will be a 21% increment.  

Step-by-step explanation:

The value of the house when Mr. Porter bought the house was d.

The present value of the house is given by d + 0.21d = 1.21d.

Hence, the increase in the value of the house is 0.21 d and the final value of the house is 1.21d.

So, if Mr. Porter claims that the value of his house has increased by 121%, then his claim is wrong. The increase in value is only by 0.21d i.e. by 21% and after this increment, the value becomes 1.21d i.e. 121%.

Therefore, his claim is not correct and it will be a 21% increment. (Answer)

The sales tax on a $250 computer is $17.50. find the sales tax rate
Vedmedyk [2.9K]
Tax=tax rate times cost of product
tax=17.50
cost of product=250
17.50=rate times 250
divide both sides by 250
17.50/250=rate
0.07=rate
percent means parts out of 100
0.07/1 times 100/100=7/100=7%
7%=rate

answer is 7% tax

A bus leaves Los Angeles at 8am moving northeast at 60 mph. Three hours later, a truck leaves the same place traveling 1 2/3 tim
love history [14]

Answer:

7.5 hours

Step-by-step explanation:

Using the variable 't' for time, you can set up an equation to find out how long it will take the truck to catch up to the  bus.  Since the bus is traveling at 60mph and the truck is traveling 1 2/3 times faster, we need to first find the rate of the truck:

1\frac{2}{3}=\frac{5}{3}

\frac{60}{1}*\frac{5}{3}=\frac{300}{3}=100mph

Using 't' and the knowledge that they will have traveled the same distance we the truck catches up to the bus and the fact that the truck left 3 hours later:

60t = 100(t - 3)  or 60t = 100t - 300

Solve for 't':  60t - 100t = -300 or -40t = -300  so, t = 7.5 hours

Firdavs [7]

Answer:

a. Another letter that have corresponding angles is the letter 'E'

b. Another letter that have alternate angles is the letter 'N'

Step-by-step explanation:

The capital letter 'F' can be described as letter can be presented as follows;

Two horizontal parallel lines touching and perpendicular to a common transversal

Therefore, the parallel lines in the letter 'F' and their common transversal form corresponding angles below each parallel line and the common transversal

The two horizontal lines in the capital letter Z and the inclined transversal form alternate angles between the transversal and the parallel lines, in the region between the parallel lines and on opposite sides of the transversal

a. Another letter that have corresponding angles is the letter 'E'

b. Another letter that have alternate angles is the letter 'N'

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

4x + 5y = -12

-2x + 3y = -16

<u>Step 2: Rewrite Systems</u>

-2x + 3y = -16

  1. Multiply everything by 2:                    -4x + 6y = -32

<u>Step 3: Redefine Systems</u>

4x + 5y = -12

-4x + 6y = -32

<u>Step 4: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                    11y = -44
  2. Divide 17 on both sides:                  y = -4
