Answer:
Brian's average speed: 14.73 mile/hour
The traveled distance by skiing he estimated: 11.0475 miles.
As the information provided in table, the time he spent for skiing is 0.75
=> The distance Brian traveled by skiing: 14.73 x 0.75 = 11.0475 (miles)
=> Brian's product is correct.
=> Rounding to the nearest whole number => 11.0475 = 11 (miles)
Rounding the Brian's average speed to the nearest whole number:
=> 14.73 = 15 mile/hour
Round the activity time to the nearest whole number:
=> T = 3 + 1.45 + 1.2 + 0.75 = 6.4 = 6 (hour)
Hope this helps!

Wow, what a coincidence, I just learned this at school today!
1. Slope
M= yb-ya/xb-xa
M= 8-4/8-6
M= 4/2
M= 2
2. Y-intercept
Y= mx + b
4 = (2)(6) + b
4 = 12 + b
4 = 12 + b
-12 = - 12 + b
-8 = b
Therefore, the equation is Y = 2x - 8
The solution for the given inequality, m < 3 is 2. According to the inequality, the possible values for “m” must be lesser than 3.
Answer:
Total area to be painted in gold = 24000 cm²
Step-by-step explanation:
Total height of the stairs = 120 cm
Total standing stairs = 4
Therefore, height or width of one standing stair as shown in the picture,
= 
= 30 cm
Length of every stair has = 100 cm
Every horizontal and vertical stair has the same area.
Area of one stair = Length × Width
= 100 × 30
= 3000 cm square
There are 4 horizontal and 4 vertical similar stairs to be painted in gold.
Total area to be painted in gold = 8 × Area of one stair
= 8 × (3000)
= 24000 cm²
Total area to be painted in gold = 24000 cm²
Answer:
c. 138 feet
Step-by-step explanation:
h(t) = −16t^2 + 83t + 33
At3 seconds
h(3) = -16(3^2) + 83(3) + 33
h(3) = -16(9) + 249 + 33
h(3) = -144 + 249 + 33
h(3) = 138
c. 138 feet
