Kenny bought a 50-pound bag of chicken feed for $29.98 and a 25-pound bag for $15.49. Can you use proportional reasoning to find the price of a 40-pound bag? Explain.
Yes; The ratio of pounds to cost is equivalent.


Yes; The unit rates are the same.


Yes; The line containing these two points passes through the origin.


No; There is no constant of proportionality.

Answer:

There are 5,280 feet in a mile.

There are 60 minutes in an hour.

As a quick check, does this answer look correct? If you were travelling 5 miles per hour slower, at a steady 60 mph, you would be driving 60 miles every 60 minutes, or a mile a minute. If you're driving 65 miles per hour, then, you ought to be going just over a mile a minute — specifically, 1 mile and 440 feet.

While it's common knowledge that an hour contains 60 minutes.

Step-by-step explanation:

If your car is traveling 65 miles per hour, then it is also going 343,200 feet (65 × 5,280 = 343,200) per hour. Then, you can divide the total feet per hour by 60, and you know that your car is traveling 5,720 feet per minute.

Answer: A right angle is also equal to 90 degrees The sides that include the right angle are perpendicular and the base of the triangle. The third side is called the hypotenuse, which is the longest side of all three sides.

Answer:

45 ∘,45 ∘ ,90 ∘

Step-by-step explanation:

Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘

. let the other two angles be x

Thus, sum of angles = 180

90+x+x=180

2x=90

x = 45 ∘

The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘

Answer:

y = 120

Step-by-step explanation:

If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.

Answer:

120

Step-by-step explanation:

set up a proportion: 80/10=y/15

solve: 80*15=10y

1200=10y

y=120

Answer:

Step-by-step explanation:

Given ratio,

→ 9:13

The 5 equivalent ratios are,

→ (9 × 2):(13 × 2) = 18:26

→ (9 × 3):(13 × 3) = 27:39

→ (9 × 4):(13 × 4) = 36:52

→ (9 × 5):(13 × 5) = 45:65

→ (9 × 6):(13 × 6) = 54:78

Hence, these are the ratios.

The correct answer is y = -2x.

Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by  [tex]\alpha[/tex] .  

Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,

                                          a  [tex]\alpha[/tex]  b

                                 =>    [tex]a/b = k[/tex] ( where k is constant)

                                 =>     [tex]a = kb[/tex] [tex]--- >[/tex] 1

Substitute a=x and b=y in 1, and then we get

                                          [tex]x = ky[/tex]

Therefore, the general form of an equation which satisfies direct proportion is x = ky.

[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex]  are not in the form of [tex]x = ky[/tex].

So, The equation of direct proportion is y = -2x.

c) -20/27

Step-by-step explanation:

Given problem,

→ (-8/9) × (5/6)

Then the product will be,

→ (-8/9) × (5/6)

→ (-8 × 5)/(9 × 6)

→ -40/54

→ -20/27

Hence, answer is -20/27.
