You can subtract 44 and from there tell how many hours it took,which is 3.Now you can set it up.

179 = 44 + 3h
-44. -44
-------------
135 = 3h
Now you divide 135 by 3 and get that for every hour $45 was charged

Hope this helped :D

What direction would a sprite go if you constantly decreases its my property? ​
Elodia [21]

Answer:

This lesson combines the Draw Loop that students first saw in Lesson 7 and the Counter Pattern that they learned in Lesson 8 to create programs with purposeful motion. By either incrementing or decrementing sprite properties, such as sprite.x, you can write programs that move sprites in expected patterns, instead of the randomization that we used in the past. The animations that students learn to create in this lesson lay the foundation for all of the animations and games that they will make throughout the rest of the unit.

Step-by-step explanation:

(1/4)^x= 256
iren [92.7K]
X= -4
Work:  1^x/4^x=256
1^x= 256 * 4^x
In 1^x = In 256 * 4^x
xIn1 = In 256+ In4^x
x*0= xIn 4 + In 2^8
0= xIn 2^2 + 8In 2
x In 2^2 + 8In 2 =0
x* 2In 2 + 8In 2=0
2In 2x + 8In 2=0
2In 2x = -8In 2
x= -8/2
x=-4

Dominick is training for a race. He spends 0.75 hours running each time he runs and 1.5 hours swimming each time
umka2103 [35]

Answer:

The possible graph is "A". A further explanation is given below.

Step-by-step explanation:

The given values are:

Dominick spends on running

= 0.70 hours

He spends on swimming

= 1.5 hours

This week,

Dominick spends more than six hours.

If,

Number of runs be "x".

Number of swimming be "y".

then,

⇒ 0.75x+1.5y>6

⇒ 75x+150y>600

⇒ x+2y>8

Therefore, x+2y=8

x = 0

y = 4

So the above is the correct answer.
