Mr. porter owns a house. when he first bought the house it was valued at d dollars. since then, the value of the house has increased. 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.

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)

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
