How does a "for every" statement show a ratio comparison? PLEASE ANSWER ITS SO LATE WHERE I AM AND IM TIRED

Neporo4naja [7]

Because it states that for every amount of something there is a certain amount based on something else. For example, for every apple i have, i will have two bananas. This will go into the ratio 1:2. Hope this helps☺

the formula below changes degrees Fahrenhiet to degrees Celsius 5/9(F-32). what is the temperature in degrees Celsius, for -4 Fa

lesya [120]

Substitute -4 for F and do the arithmetic.
.. C = (5/9)*(-4-32) = (5/9)(-36) = -20

-4 °F corresponds to -20 °C.

World war 1 lasted from August 4th 1914 until November 11th, 1918. During this time an estimated 10 million lives were lost. Abo

Kryger [21]

The question is so dry, mechanical, and devoid of emotion
that it's terrifying.

There is no way to assign a number to "How many people were
dying per day", and I would prefer not even to think about it in
those terms.

-- The period of time from August 4, 1914 until November 11, 1918 is 1,560 days.

-- The "average", or better, the "unit rate" of 10 million events in 1,560 days
is the quotient

   (10,000,000 events) / (1,560 days)

   = 6,410.3 events per day

   = 267.1 events per hour

   =   4.45 events per minute.

Reciprocally, this is a unit rate of

13.48 seconds per event,
      sustained continuously for 4.274 years !

When will we ever learn ! ?

Given the system of equations, what is the solution?

Elena L [17]

Answer:

{(-34/7, -16/7)}

Step-by-step explanation:

Rearrange values, multiply to solve for x.

(5) 2y = 3x + 10

(-2) 5y = 4x + 8

Solve for x.

10y = 15x + 50 ↓

-10y = -8x -16

Combine and evaluate.

0 = 7x + 34

Subtract 34 from both sides.

7x = -34

Divide both sides by 7.

x = $\frac{-34}{7}$

Plugin x value into either equation to solve for y.

2y = (3 × $\frac{-34}{7}$ ) + 10

2y = $\frac{-102}{7}$ + 10

2y = $\frac{-32}{7}$

y = $\frac{-16}{7}$

Kenisha uses the Fermi process to estimate the number of dollar bills that would cover her driveway. Her driveway is rectangular

shepuryov [24]

Answer:

option A

9×10^4/2×10^2

Step-by-step explanation:

Given in the question,

length of dollar bill = 6

width of dollar bill = 3

area of dollar bill = L x W

= 6 x 3

= 18inches²

length of driveway = 30

width of driveway = 20

area of driveway = L x W

= 30 x 20

= 600 ft²

1 ft² = 144 inches²

600 ft² = 86400 inches²

Number of dollar bills that would cover Kenisha driveway = 86400 / 18

Which can also be written as

86400 = 9 x 10 $^{4}$

18 = 2 x 10²

$\frac{9x10^{4} }{2x10^{2} }$
