which is faster: drive a car at a rate of 40 kilometers per hour or drive a car at a rate of 15 meters per second
Answer:
Step-by-step explanation:
Let's convert one of these measurements so that both measurements have the same units. 15 m/sec is equivalent to 0.015 km/sec, which in turn is equivalent to
0.015 km 3600 sec
--------- -------- ----------------- = 54 km/hr
1 sec 1 hr
This latter result (54 km/hr) is faster than (40 km/hr).

A square pyramid on top of a rectangular prism. The rectangular prism has a length of 4 meters, width of 4 meters, and height of 4 meters. The square pyramid has triangular sides that have a height of 3 meters and side length of 5 meters. Compare the surface area of the composite figure to the surface area to the combined surface areas of the figures if they were separated. The composite surface area would be the surface area of the rectangular prism plus the surface area of the square pyramid considered separately. You should not count the pyramid’s as part of the composite figure’s surface area.
Answer:
The square pyramid by itself has a surface area of 55 meter[tex]s^2[/tex].
The rectangular prism by itself has a surface area of 96 meter[tex]s^2[/tex].

You have to add all the money up then subtract it by the following money you earned.
Step-by-step explanation:
45.35+45.25= 90.5
1.39x75=104.25
0.68x8=5.44
68.72x2=137.44
1.85x37=68.45
0.13x900=117
52.85x12=634.2
52.85x2=105.7
19.49x3=58.47
2750-1321.45=1428.55
(the number 1321.45 came from everything added together, which i then subtracted from 2750 to get 1428.55 as your remaining balance.

Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.

Find the area of the clock
Use 3.14 for pi
Area = PI x radius^2
The diameter is given as 25 inches, the radius is 1/2 the diameter.
Radius = 25/2 = 12.5 inches
area = 12.5^2 x 3.14
Area = 490.625 square inches

4 miles per hour
Step-by-step explanation:Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.
Proportion
First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.
This creates the proportion [tex]\frac{12miles}{3hours}[/tex]So, the rate we are given is 12/3.
Unit Rate
To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.
12/3 equals 43/3 equals 1So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.
Graph
Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.
