(c) One lorry travels from your town to another town. The lorry reaches a top speed

Katen [24]

Answer:

The average speed is 24 km/h less than the top speed of the lorry.

Step-by-step explanation:

The top speed of the lorry is the highest speed reached during transit, while its average speed is the mean speed attained

Given:.

Top speed of the lorry = 90 km/h

Average speed of the lorry = 66 km/h

Then,

The difference between the speed reached = top speed - average speed

= 90 - 66

= 24 km/h

Therefore, the average speed is 24 km/h less than the top speed of the lorry.

Please help me! Geometry! Transition math

andrew-mc [135]

Answer:

total area = 18.28 in.^2

perimeter = 16.28 cm

Step-by-step explanation:

Area:

The total area of the figure is the sim of the area of the rectangle and the area of the semicircle.

total area = LW + (1/2)(pi)r^2

total area = (4 in.)(3 in.) + (1/2)(3.14)(2 in.)^2

total area = 12 in.^2 + 6.28 in.^2

total area = 18.28 in.^2

Perimeter:

The perimeter of the figure is the sum of the lengths of the left side, bottom side, and right side of the rectangle and the circumference of the half circle.

perimeter = 3 cm + 4 cm + 3 cm + (1/2)(pi)d

perimeter = 10 + (1/2)(3.14)(4 cm)

perimeter = 10 + 6.28 cm

perimeter = 16.28 cm

CAN SOMEONE HELP ME I’LL GIVE OUT BRAINLIEST THANK YOU

Answer:

112.5 miles.

Step-by-step explanation:

2 cm = 25 miles

The question is asking you for the distance between two cities, and is giving you the information that it's 9 cm on the map.

2 cm + 2 cm + 2 cm + 2 cm = 8 cm

25 divided by 2 is 12.5, which would give you 1 cm for the map key.

2 cm + 2 cm + 2 cm + 2 cm + 1 cm = 9 cm

25 miles + 25 miles + 25 miles + 25 miles + 12.5 miles = 112.5

alex is building a rectangular fence around his yard. The total perimeter of the fence is 68 feet and the area of the yard is 25

Westkost [7]

Let
x-------------> length of the fence
y-------------> width of the fence

we know that
Area of rectangle=x*y
perimeter of rectangle=2x+2y
A=250 ft²
P=68 ft

then
250=x*y-----------> x=250/y equation 1
68=2x+2y-----------> equation 2

using a graph tool---------> to resolve the system of equations
see the attached figure

the solution is the point 1 (10.755,23.245) and the point 2 (23.245,10.755)

for the point 1
x=10.755 ft
y=23.245 ft

for the point 2
x=23.245 ft
y=10.755 ft

the answer is
<span>the dimensions of the fence are
23.245 ft x 10.755 ft
</span>or
10.755 ft x 23.245 ft
