The result of our calculations about the rate and time are:

  • r=d/t
  • 200000m/hr
  • 200km/hr
  • km/hr

<h3>What is rate?</h3>

Rate can be regarded as the given object with respect to time.

falcon flies= 800,000 meters

t= 4 hours

We were given the  formula as (d = rt)

d= distance

r = rate

t = time

We can make our calculations as:

part a:

r=d/t

part b:

falcon's rate in meters per hour = 800,000 meters / 4 hours = 200000m/hr

part c:

falcon's rate in kilometers per hour=(200000m/hr *(1/1000)=200km/hr

part d:

km/hr

Roxanne has 1/2 as many beads as Sherrie. The number of beads Sherrie has is 4/5 that of Ting Ting's. Ting Ting has 165 beads. H
gregori [183]
165 Ting Ting's beads* (4 Sherrie's beads/ 5 Ting Ting's beads)= 132 Sherrie's beads.
132 Sherrie's beads* (1 Roxanne's bead/ 2 Sherrie's beads)= 66 Roxanne's beads.
Now that we know the number of beads Roxanne and Ting Ting have, let's subtract:
165 beads- 66 beads= 99 beads.
Hope this would help :))

Find the area pls- i need help
Tresset [83]

Answer:

1. 36 sq un

2. 40 sq un

3. 20 sq un

Step-by-step explanation:

The answer for number one is 36 square units because the rectangular area is 24 sq un and the triangular area is 12 sq un so I added them to get 36 sq un. The second answer is 40 sq un because if you cut the shape into 2 shapes you get 2 equal trapezoids. Each trapezoid is 20 sq un so I multiplied it by two to get 40 sq un. The third answer is 20 because the side triangles are 2 sq un each and the square on the bottom is 16 sq un. By the way, sq un means square units lol.
