At the elementary school, the fourth graders Jamal and Dinah are still eating lunch as they come into math class. Someone has left a book on the floor and they both trip. As they each hit the floor, the food they are carrying flies across the room directly toward Harold, who is showing off his latest dance moves. As Jamal and Dinah watch in horror, Jamal’s cupcake and Dinah’s sandwich splat right on top of Harold’s head! Jamal’s cupcake flies on a path that would have landed on the floor 22 feet away from him if it had not hit Harold. Dinah’s sandwich flies on a path that would have landed on the floor 26 feet away from her if it had not hit Harold. Jamal’s cupcake flies 8 feet high, while Dinah’s sandwich reaches a height of 5 feet before hitting Harold.

How tall is Harold? Once you have the equations, you may use Desmos to help find the answer.

This question uses a numeric answer. Type in just the number part answer (no letters!) and round to 2 decimals.

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

(a + b) (a^2 - a b + b^2)
