Answer:
6.4 minutes, or 6 minutes and 24 seconds
Step-by-step explanation:
She is running 4 laps, so she is running 1600 meters total. If she runs 250 meters per minute, divide 1600 by 250 to determine how many minutes it will take...
1600/250 = 6.4
Which is 6 minutes + 0.4 minutes
*there are 60 seconds in a minute, so the 0.4 represents 40% of another minute. Multiply 60 by 0.4 to see how many seconds this is...
(0.4)60 = 24 seconds,
So she ran the laps in 6 minutes and 24 seconds
I believe the formula is lxwxh if so it's 20 x 30 x 4= 2400 i hope this helped
Answer:
f = -3 , 5/2
Step-by-step explanation:
8f² + 4f - 60 = 0
Divide the entire equation by 4
2f² + f - 15 = 0
Product = -30
Sum = 1
Factors = -5 , 6 {(-5)*6 = -30 and -5 +6 = 1}
2f² + f -15 = 0 {Rewrite the middle term using the factors}
2f² + 6f - 5f -15 = 0
2f(f + 3) - 5(f + 3) = 0
(f +3) (2f - 5) = 0
f +3 = 0 ; 2f -5 = 0
f = -3 ; 2f = 5
f = 5/2
<span>The missing value that represents the rate for Marie is 1/60. As mentioned in the table, rate (r) is the part (p) per minute (t). Let's check if it works for Lea. If p = 1/80t, then r = (1/80t)/t = 1/80 * t/t = 1/80 * 1 = 1/80. So, the formula works. Now, calculate the rate for Marie. If p = 1/60t, then r = (1/60t)/t = 1/60 * t/t = 1/60 * 1 = 1/60</span>
Answer:
1) Photographer B (4%)
2) Photographer D (27%)
3) Photographer C (29%)
4) Photographer A (40%)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Four photographers are taking pictures at a school dance. Photographer A takes 2/5 of the pictures, Photographer B takes 4% , Photographer C takes 0.29 , and Photographer D takes 27/100 . Which choice lists the photographers in order from least to greatest by the amount of pictures they take?
we know that
1) Photographer A takes 2/5 of the pictures
That means
the amount of pictures take by photographer A in percent form is equal to multiply the fraction by 100
---> percentage form
2) Photographer B takes 4%
3) Photographer C takes 0.29
That means
the amount of pictures take by photographer C in percent form is equal to multiply the decimal number by 100
---> percentage form
4) Photographer D takes 27/100
That means
the amount of pictures take by photographer D in percent form is equal to multiply the fraction by 100
---> percentage form
Lists the photographers in order from least to greatest by the amount of pictures they take
1) Photographer B (4%)
2) Photographer D (27%)
3) Photographer C (29%)
4) Photographer A (40%)
