Ratios are like fractions. 5:6 is the same as 5/6.

A ratio says how much of one thing there is compared to another thing.

Example. Say if there 4 apples and 3 blueberries 

The ratio to apples to berries will be 4:3

But if its blueberries to apples it would be 3:4

We bought 3 pairs of socks and 2 handkerchiefs for $ 1.45 and, yesterday, 2 pairs of stocking and 5 handkerchiefs for $ 1.75. De
alexgriva [62]
Equations for the numbers of pairs of socks (s) and handkerchiefs (h) can be written as
  3s +2h = 1.45
  2s +5h = 1.75

These can be solved by any of your favorite means to find
  s = 3.75/11 ≈ 0.341
  h = 2.35/11 ≈ .214

The price of a pair of socks and a handerchief is $0.34 +0.21 = $0.55.

PLEASE HELP!! WILL GIVE BRAINLIEST!!!
Murrr4er [49]

Answer:

option D

Step-by-step explanation:

Jerry solved this equation: 

3(x-\frac{1}{4})=\frac{13}{6}

In the first step , she multiplied 3 inside the parenthesis

1. 3x-\frac{3}{4}=\frac{13}{6}

In step 2, 3/4 is added on both sides

2. 3x-\frac{3}{4}+\frac{3}{4}=\frac{13}{6}+\frac{3}{4}

In step 3, we take LCD 12

3. 3x=\frac{26}{12}+\frac{9}{12}

In step 4, add the fractions

4. 3x=\frac{35}{12}

Here, 3 or 3/1 are same.

\frac{3}{1}x=\frac{35}{12}

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

\frac{1}{3} \cdot \frac{3}{1}x=\frac{1}{3} \cdot \frac{35}{12}

x=\frac{35}{36}

In step 5, he should have multiplied both sides by 1/3

Use the position equation given below, where s represents the height of the object (in feet), v0 represents the initial velocity
iris [78.8K]

Answer:

(a) 7.5 seconds

(b) The horizontal distance the package  travel during its descent is 1737.8 ft

Step-by-step explanation:

(a) The given function for the height of the object is s = -16·t² + v₀·t + s₀

The initial height of the object s₀ = 900 feet

The initial vertical velocity of the object v₀_y = 0 m/s

The time it takes the package to strike the ground is found as follows;

0 = -16·t² + 0×t + 900

900 = 16·t²

t² = 900/16 = 62.25

t = √62.25 = 7.5 seconds

(b) Given that the horizontal velocity of the package is given as 158 miles/hour, we have

158 miles/hour = 231.7126 ft/s

The horizontal distance the package  covers in the 7.5 second of vertical flight = 231.7126 ft/s × 7.5 s = 1737.8445 feet = 1737.8 ft to one decimal place

The horizontal distance the package  travel during its descent = 1737.8 ft.
