Height is 2ft. More than its width. If the total area is 99ft squared , determine the dimensions of the painting.

lesantik [10]

Answer: $9\times 11\ ft^2$

Step-by-step explanation:

Given

Height is $2\ ft$ more than its width

Suppose the width is $x$ . So, height becomes $x+2$

Area of the painting is $99\ ft^2$

Area is the product of width and height

$\therefore 99=x(x+2)\\\Rightarrow 99=x^2+2x\\\Rightarrow x^2+2x-99=0\\\Rightarrow x^2+11x-9x-99=0\\\Rightarrow (x+11)(x-9)=0\\\Rightarrow x=-11,9$

Neglect the negative values

$\text{Width =}9\ ft\\\text{height =}9+2=11\ ft$

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Richard's cumulative GPA for 3 semesters_ was 2.0 for 42 credits. His fourth semester GPA was 4.0 for 14 course units. What is R

Phoenix [80]

Answer:

Richard's cumulative GPA = 2.5

Step-by-step explanation:

Richard's cumulative GPA for 3 semesters was 2.0 for 42 credits.

Average = 2

Total credits = 42

Average = sum of terms/total no of terms

2 = sum of terms/42

sum of terms = 84 ....(1)

His fourth semester GPA was 4.0 for 14 course units

Average = 4

Total credits = 14

sum of terms = 56 .....(2)

Average for 4 semesters,

$A=\dfrac{84+56}{42+14}\\\\A=2.5$

Hence, Richard's cumulative GPA for all 4 semesters is 2.5.
