Answer:
Step-by-step explanation:
Let s represent the speed of the bus.
From the information given, the bus needs to cover a distance of 240 km in less than 5 hours. The formula for calculating the speed of the bus, s is expressed as
Speed, s = distance covered by the bus/ time taken to cover the distance
Therefore,
Speed, s = 240/5 = 48 km/hr
A higher speed would ensure the bus covers the distance in less than 5 hours. Therefore, the inequality that represents the speed (s) of the bus would be
s ≥ 48
Answer:
92 m
Step-by-step explanation:
Use the Pythagorean theorem to find the length of the shorter side.
Let w = length of the shorter side.
The perimeter is 2l + 2w = 2(30) + 2(16) = 60 + 32 = 92 m
Answer:
option C
Step-by-step explanation:
we have
using a graphing tool
see the attached figure N
The range is the interval--------> (-∞,8]
case A) 
using a graphing tool
The range is the interval--------> [-8,∞)
case B) 
using a graphing tool
The range is the interval--------> [8,∞)
case C)
using a graphing tool
The range is the interval--------> (-∞,8]
case D) 
using a graphing tool
The range is the interval--------> (-∞,-8]
Given
base=2x+6
height=x+4
and
area=56 square units
56=1/2 times (2x+6) times (x+4)
times bot sides by 2
112=(2x+6)(x+4)
expand
112=2x²+14x+24
divide both sides by 2
56=x²+7x+12
minus 56 both sides
0=x²+7x-44
factor
waht 2 numbers mulitply to get -44 and add to get 7
11 and -4
0=(x-4)(x+11)
set to 0
x-4=0
x=4
x+11=0
x=-11
false, measures can't be negative
x=4
height=x+4
height=4+4=8
base=2x+6
base=2(4)+6=8+6=14
x=4 and base=14 and height=8
Answer:
A. 6 m by 6 m
Step-by-step explanation:
You can try the different choices to see which has the largest area. Of course, the area is the product of the dimensions:
6 m × 6 m = 36 m² . . . . largest area
10 m × 2 m = 20 m²
8 m × 4 m = 32 m²
__
The largest area is that of a square, 6 m by 6 m. (choice A)
