Answer:

Triangle APB is an isosceles triangle ⇒ 3rd answer

Step-by-step explanation:

* Lets explain the how to solve the problem

- ABCD is a square

∴ AB = BC = CD = AD

∴ m∠A = m∠∠B = m∠C = m∠D = 90°

- DPC is equilateral triangle

∴ DP = PC = DC

∴ m∠DPC = m∠PCD = m∠CDP = 60°

- In the Δs APD , BPC

∵ AD = BC ⇒ sides of the square

∵ PD = PC ⇒ sides of equilateral triangle

∵ m∠ADB = m∠BCP = 30° (90° - 60° = 30) ⇒ including angles

∴ Δs APD , BPC are congregant ⇒ SAS

- From congruent

∴ AP = BP

∴ Triangle APB is an isosceles triangle

Last month, you were able to purchase 8 computers. By the middle of the current month, you were able to purchase 8 more computer

Arada [10]

Answer:

125 %

Step-by-step explanation:

Computers purchased in the last month = 8

By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16

Number of computers purchased by end of current month = 2

So,

Total computers purchased by current month = 16 + 2 = 18

We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:

$\text{Percentage Change}=\frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100\%$

Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:

$\text{Percentage Change}=\frac{18-8}{8} \times 100\% = 125\%$
