Answer:

84 cookies

Step-by-step explanation:

First, find the amount she bakes per minute. It is given that Marissa bakes 30 cookies every 15 minutes, or:

30 cookies/15 minutes = 2 cookies/minute.

Marissa bakes 2 cookies per minute. Multiply 2 with 42 minutes to find the total cookies baked in 42 minutes:

42 x 2 = 84

84 cookies is your answer.

On Martin's first stroke, his golf ball traveled \dfrac45 5 4 ​ start fraction, 4, divided by, 5, end fraction of the distance t
makvit [3.9K]

Answer: 0.395 km

Step-by-step explanation:

Let Martin distance from the hole be X

On first stroke, his golf ball traveled 4/5 of the distance to the hole. That is 4/5 X

On his second stroke, the ball traveled 79 meters and went into the hole

Total distance covered will be

X = 79 + 4/5X

X - 4/5X = 79

X - 0.8X = 79

0.2X = 79

X = 79/0.2 = 395 meters

How many kilometers from the hole was Martin when he started

X = 395/1000 = 0.395 km

Consider the series 4 + 12 + 36 ... Find the sum of the first 9 terms.​
jeyben [28]

Answer:

39364

Step-by-step explanation:

You can simplify the equation to make 4(1+3+9...) The nth term is therefore 3^{n-1} so u can substitute that into the equation so 4(3^{n-1}+ 3^{n}  + 3^{n+1}..). This would simplify to 4(3^0 +3+3^2+3^3+3^4+3^5+3^6+3^7+3^8). By simplifying this, you can make it so 4(2^2+6^2+18^2+42^2+81^2) = 4(4+36+324+2916+6561) =39364
