Answer:

It would be better to buy the regular size

Step-by-step explanation:

For regular size You would divide

16/3.36 = 4.7619

For family size you would divide

40/7.60 = 5.2631

As you can see with the regular size you would pay about $4.75 cents for every ounce but if you buy the family size then you would be paying about $5.26 for every ounce

Answer:

1 cupcake is made in 1.75 minutes.

1.75 minutes

Step-by-step explanation:

Divide 70 by 40 = 1.75.

49/28=1.75

The constant of proportionality of the given data is 0.57.

The constant of proportionality is the ratio of two proportional values at a constant value.

Now it is given that,

Time taken for icing 40 cupcakes = 70 minutes

∴ Icing of cupcakes in 1 minute = 40/70

                                                    = 0.57

Time taken for icing 28 cupcakes = 49 minutes

∴ Icing of cupcakes in 1 minute = 28/49

                                                    = 0.57

⇒ constant of proportionality = 0.57

Thus, the constant of proportionality of the given data is 0.57.

Answer:

40.9 ft

Step-by-step explanation:

Perimeter is the sum of lengths of all outer sides of the shape. Since the rectangle has two pairs of parallel lines of the same length... It is safe to assume that the unmarked side length is 10 ft (just like it's parallel counterpart)

Now it is a simple matter of adding all of the outer sides.

8ft + 10 ft + 10 ft + 8.9 ft + 4 ft = 40.9 ft

Answer: The newspaper has 2500 readers.

Step-by-step explanation:

Given: The local newspaper has letters to the editor from 50 people.

This is the 2% of all newspaper readers.

Let x be the number of all newspaper readers.

Then. 2% of x= 50

[tex]\Rightarrow\ 0.02x=50\ \ [\text{To remove }\% \text{we divide number by 100}]\\\\\Rightarrow\ x=\dfrac{50}{0.02}=\dfrac{5000}{2}=2500\\\\\Rightarrow x=2500[/tex]

Hence, the newspaper has 2500 readers.

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

He rides 27 miles in two hours, 81/2 miles in 3 hours, and 189/4 in 3.5 hours.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, A biker cycles 9 miles in 2/3 of an hour.

∴ He rides (9×3/2) is (2/3)×(3/2) hours.

He rides 27/2 miles in 1 hour.

So, He rides (27/2)×2 in 2 hours.

27 miles in 2 hours.

He rides (27/2)×3 miles in 3 hours.

81/2 miles in 3 hours.

He rides (27/2)×(7/2) miles in 7/2 hours.

189/4 miles in 7/2 hours.

The resultant vector makes a 6.3-degree angle with the horizontal force, the correct option is A.

The resultant angle between the vectors is given by

[tex]\rm \theta = tan^{-1} \dfrac{B sin\theta}{A +B cos\theta}[/tex]

The two forces have magnitude of 17.3 and 42.5 pounds.

The angle of the resultant vector is

[tex]\rm \rm \theta = tan^{-1} \dfrac{17.3\; sin\; 21.9}{42.5 +17.3 cos\;21.9}[/tex]

[tex]\rm \theta = tan^{-1}[/tex] (6.453/58.55)

[tex]\rm \theta[/tex] = 6.2886 degree = 6.3 degree.

Therefore, the resultant vector makes a 6.3-degree angle with the horizontal force.
