The book is asking if 14/20 is the same as 16/24. In other words, we want to see if 14/20 = 16/24 is a true equation or not.

Let's find out

14/20 = 16/24
14*24 = 20*16 ... cross multiply
336 = 320

Since the last equation shown above is NOT true, this makes the first equation NOT true.

The equation 14/20 = 16/24 is false so they did NOT make a proportional number of shots

An alternative route is to convert each fraction to decimal form
14/20 = 0.7
16/24 = 0.6666... (the 6's go on forever)
We get two different decimal values so this confirms our answer

The blueprint of a pool has a scale of 2 inches equals 7 feet. The scale drawing is shown below. the length is 20 and the width

AlladinOne [14]

Answer:

Part A:

Blueprint 10 inches ⇒ Actual 35 feet

Blueprint 20 inches ⇒ Actual 70 feet

Part B:

The cost of the cover is $857.5

Step-by-step explanation:

Part A:

∵ The drawing scale is 2 inches for 7 feet

∵ The length = 20 inches and the width = 10 inches

∴ The actual length = (20 × 7) ÷ 2 = 70 feet

∴ The actual width = (10 × 7) ÷ 2 = 35 feet

Part B:

∵ The cost per square foot = $0.35

∵ The area of the pool = 70 × 35 = 2450 feet ²

∴ The cost of the cover = 2450 × 0.35 = $857.5

I don’t know what to do on here it’s really hard and I need help for the answer

Alla [95]

Ok so our original fraction is:
$\frac{36 {x}^{12} }{6 {x}^{9} }$
To simplify this fraction, look for instances where the values on the top and bottom can be reduced:

For example, 36 over 6 is the same as 6 over 1, so we can simplify the fraction so it is:
$\frac{6 {x}^{12} }{ {x}^{9} }$
We can also eliminate the denominator by dividing the nominator by x^9 so:
$\frac{6 {x}^{12} }{ {x}^{9} } \div \frac{ {x}^{9} }{ {x}^{9} }$
$= 6 {x}^{3}$
And that is the simplified answer of the fraction

Hope this helped

Let csc(x) = Cosecant (x) = StartFraction 14 Over 10 EndFraction, where 0 less-than x less-than StartFraction pi Over 2 EndFract

dedylja [7]

Answer:

First Option: cos(x)

Step-by-step explanation:

What is given is csc(x) = 14/10

The graph lies in the first quadrant since 0 < x < pi/2

Create a triangle:

The length across is 14

The adjacent is 10

The length of the shorter side is root 96

Use the pythagorean theorem

BC^2 = 14^2 - 10^2

BC^2 = 196 - 100, 96

BC^2 = root 96/14

Recall SOH-CAH-TOA

Adjacent over Hypotenuse is cos

That is how the answer is cos(x)
