Answer:

Step-by-step explanation:

g(x - 6)= 3(x - 6)^2 + 5(x - 6) - 5

= 3(x^2 - 12x + 36) + 5x - 30 - 5

= 3x^2 - 36x + 108 + 5x - 35

A sporting goods store buys a basketball for $10.00 and then adds a 110% markup to the price. How much will the basketball sell

sweet-ann [11.9K]

Answer: The basketball will sell for $21 .

Step-by-step explanation:

Hi, to answer this question, first, we have to multiply the cost of the basketball (10) by the percent markup in decimal form (divided by 100).

Mathematically speaking:

10 x (110/100) = $11

Now, we have to add the markup amount (11) to the cost (10) to obtain the selling price:

10 +11 = $21

The basketball will sell for $21 .

Team tool bella canoed 15 3/4 miles in 5/4 hours. What was their average rate of speed in mph

luda_lava [24]

Average speed is 12.6 miles per hour

Solution:

Given that team tool bella canoed $15\frac{3}{4}$ miles in $\frac{5}{4}$ hours

To find: average rate of speed in miles per hour

From given information,

$distance = 15\frac{3}{4} \text{ miles } = \frac{15 \times 4+3}{4} = \frac{63}{4} \text{ miles}$

$time = \frac{5}{4} \text{ hours}$

To find the speed we use the below formula,

$speed = \frac{distance}{time}$

Substituting the given values we get,

$speed = \frac{\frac{63}{4}}{\frac{5}{4}}\\\\speed = \frac{63}{4} \times \frac{4}{5} = \frac{63}{5} = 12.6$

Thus average speed is 12.6 miles per hour
