To solve a quadratic equation using completing the square method,
STEP 1
Divide through by the coefitient of the squared term.
Looking at the solutions of Rashid and Tia, we notice that Rashid did not divide through by the coefficient of

.
Therefore, Rashids solution is wrong.
We solve the equation using completeing the square as follows:
Answer:
B. $264.00
Step-by-step explanation:
==>The image that shows the pattern of the arrangement of tiles consists of:
2 large tiles = $0.96*2 = $1.92
8 small tiles = $0.26*8 = $2.08
This implies that $4 would need to be spent to cover 1ft²
Therefore, to cover an area of 22ft by 3ft, it would cost Fred the following below:
Area to be covered = 22×3 = 66ft²
$4 --> 1ft²
x$ ---> 66ft²
= (66 × 4)/1
= $264.00
Answer:
132
Step-by-step explanation:
The angles have to add up to 720
Answer:
125
Step-by-step explanation:
500*0.25=500*1/4
Solve
500*1/4
=500/4
=125
Determine first the difference between the incorrectly measured board and the correct one. The subtraction would result to 1.2 ft. The percent error is calculated by dividing this value by the correct value and then multiply by 100%. (1.2 ft / 12 ft) x 100% = 100%. Thus, the percent error is 10%.
