What is the quotient of 2 1/9÷3 4/5

Karolina [17]

Answer:

$\frac{5}{9}$

Step-by-step explanation:

$2 \frac{1}{9} \div 3 \frac{4}{5} \\ \\ = \frac{2 \times 9 + 1}{9} \div \frac{3 \times 5 + 4}{5} \\ \\ = \frac{18 + 1}{9} \div \frac{15 + 4}{5}\\ \\ = \frac{19}{9} \div \frac{19}{5}\\ \\ = \frac{19}{9} \times \frac{5}{19} \\ \\ = \frac{5}{9}$

Reggie needs 24 feet of rope to make a tire swing. He has 10 yards of rope. Is this enough for him to make his swing? Explain.

Luden [163]

Answer:

8 yards < 10 yards

He has enough.

Step-by-step explanation:

1 yard = 3 feet

y yards = 24 feet

$\frac{1}{3} :\frac{y}{24}$

y · 3 = 1 · 24

3y = 24

3y ÷ 3 = 24 ÷ 3

y = 8

24 feet = 8 yards

8 yards < 10 yards

One year Terry had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitch

Colt1911 [192]

Answer:

Their respective z-scores are:

Thomas : -2.15279

Karla : -1.40221

Which player had the better year relative to their peers, Terry or Karla ?

Terry had a better year because he had a lower Era and he was a better pitcher.

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean

σ is the population standard deviation.

any male pitcher at his school,

For Thomas:

z = (x-μ)/σ

x = 2.85 μ = 4.893 σ = 0.949.

z = 2.85 - 4.893/0.949

z = -2.15279

For Karla

z = (x-μ)/σ

x = 2.95 μ = 4.348 σ = 0.997.

z = (2.95 - 4.348) /0

z = -1.40221

Their respective z-scores are:

Thomas : -2.15279

Karla : -1.40221

Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)

Terry had a better year because he had a lower Era and he was a better pitcher.

Which operation could we perform in order to find the number of milliseconds in a year? 60 * 60 * 24 * 7 * 365 1000 * 60 * 60 *

Tom [10]

Use the following abbreviations:
y = year,
d = day,
h = hour,
min = minute,
s = second,
ms = millisecond.

Then
$1 \, y = (1 \, y)*(365 \, \frac{d}{y} )*(24 \, \frac{h}{d} )*(60 \, \frac{min}{h} )*(60 \, \frac{s}{min} )*(1000 \, \frac{ms}{s} )$

Therefore, the correct calculation is
1000 * 60 * 60 * 24 * 365

Answer: 1000 * 60 * 60 * 24 * 365
