Answer:

42 cups of dog food.

Step-by-step explanation:

Rocky ate 3 cups of dog food each day for two weeks, there's 7 days in a week, if you multiply 14 ( number of days in 2 weeks) and 3( the number of dog food each day) you would get 42 because 7 days are in 1 weeks and if you add another 7 days, you would get 14 days and by multiplying that by 3, the dog food Rocky ate each day, you would get 42, the answer to your question. Hope this answers your question!

Step-by-step explanation:

first and foremost start off with a proper FBD (I drew in the forces and acceleration just to refer back to it quicker, assume right and up are positive)

a) F net = Forces aiding the movement - forces opposing

if the box is sliding to the right then we've got

Fnet = 26 + (-3)

[notice how I wrote that they're both being added because they're vector forces]

Fnet = 23 N

b) using Newton's second law of motion, F = ma, we can find the mass

Fnet = ma

rearrange for mass

M = Fnet/a

M = 23 N / 2.0 ms^-2

M = 11.5 Kg

The net force is 23.00 N to the right. The mass of the desk is 11.5 kg.

a. Calculate the net force:

The net force is the vector sum of all the forces acting on an object. In this case, the force of Brandon pulling the desk to the right is 26.00 N, and the force of friction to the left is 3.00 N. Since the friction force is in the opposite direction of the pulling force, we subtract it. Therefore, the net force is 26.00 N - 3.00 N = 23.00 N to the right.

b. If the desk accelerates at 2.0 m/s2, find the mass of the desk:

The equation for calculating the net force on an object is F = ma, where F is the net force, m is the mass, and a is the acceleration. Rearranging the equation to solve for mass, we have m = F/a. Plugging in the values, mass = 23.00 N / 2.0 m/s2 = 11.5 kg.

The triangle C can be solved using the law of sines.

'The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.'

According to the given problem,

We know,

Law of sines = [tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]

In triangle C,

Third angle = 180 - ( 70 + 30 )

                   = 180 - 100

                   = 80°

⇒ [tex]\frac{10}{sin30 }= \frac{b}{sin70} =\frac{c}{sin80}[/tex]

⇒ [tex]\frac{10}{sin30}= \frac{b}{sin70}[/tex]

⇒ 20 × 0.9396 = b

⇒ b = 18.8 m

⇒ [tex]\frac{10}{sin30}=\frac{c}{sin80}[/tex]

⇒ 20 × 0.9848 = c

⇒ c = 19.7 m

Hence, we can conclude that tringle C can be solved using the law of sines.

Answer:

About 5.73 cm

Step-by-step explanation:

C=2πr so

36=2πr (divide by 2)

18=πr (using 3.14 as π)

18=(3.14)r (divide by 3.14)

r=5.732484076 so

R≈5.73 cm

Final answer:

The radius of a circle with a circumference of 36cm is approximately 5.73cm, calculated by dividing the circumference by the product of 2 and Pi (
).

Explanation:

Calculating the Radius from the Circumference

The circumference of a circle is closely related to its radius through the mathematical constant  which is approximately 3.14159. The circumference (C) can be expressed using the formula C = 2
r, where r is the radius. Given that the circumference is 36cm, we can rearrange the formula to solve for the radius: r = C / (2
r). Substituting the given circumference into the equation, we get:

r = 36cm / (2
3.14159)

By performing the division, we can find the radius of the circle:

r = 36cm / (2 * 3.14159)
r = 36cm / 6.28318
r ≈ 5.73cm

Therefore, the radius of the circle is approximately 5.73cm.

Answer:

height = 11.67 units

Step-by-step explanation:

A parallelogram is a quadrilateral with 2 pairs of parallel sides. This means opposites sides are parallel to each other. Opposite angles and sides are congruent.

From your question the base of the parallelogram is given as 12 units and the sides is 10 units. The area of the parallelogram is given as 140 units². What is left is the height of the parallelogram.

Using the formula for finding the area of a parallelogram, the height can be found.

area of a parallelogram = base × height

base = 12 units

height = ?

area = 140 unit²

area of a parallelogram = base × height

let

h = height

140 = 12h

divide both sides by 12

h = 140/12

h = 11.6666666667 units

height = 11.67 units

Answer:

45 bags of candy

Step-by-step explanation:

The first thing is to calculate the money Jordan has, we know that by multiplying the number of bags by their price, that is:

30*12 = 360

I mean, he's got $360, now with this money he wants to buy $8 bags, so it would be

360/8 = 45

That means I could buy 45 bags of candy if they cost $8

Jordan can purchase 20 bags of candy for $8.

Jordan purchased 30 bags of candy for $12. At that rate, to find out how many bags of candy he can purchase for $8, we first calculate the cost per bag of candy by dividing the total cost by the number of bags purchased. This gives us a rate of $0.40 per bag of candy ($12/30 = $0.40). To determine how many bags of candy Jordan can purchase for $8, we then divide $8 by the cost per bag, which is $0.40.

Calculating, $8/$0.40 = 20 bags of candy. Thus, for $8, Jordan can purchase 20 bags of candy at the same rate.

P(x) = [tex]x^{4}[/tex] - 7x² + 12

Step-by-step explanation:

Given zeros x = 2, x = - 2, x = [tex]\sqrt{3}[/tex], x = - [tex]\sqrt{3}[/tex]

Then the factors are (x - 2), (x + 2), (x - [tex]\sqrt{3}[/tex] ), (x + [tex]\sqrt{3}[/tex] )

and the polynomial is the product of the factors, that is

P(x) = (x - 2)(x + 2)(x - [tex]\sqrt{3}[/tex] )(x + [tex]\sqrt{3}[/tex] ) ← expand in pairs using FOIL

      = (x² - 4)(x² - 3) ← distribute

Answer:

B.) 90

Step-by-step explanation:

Since the ratio is 3:8, the fraction would look something like the following.:

[tex]\frac{3}{8} =\frac{?}{240}[/tex]

We know that there are 240 band members in this scenario. What do you multiply 8 by to get 240? 30.

[tex]\frac{3*30}{8*30} =\frac{90}{240}[/tex]

To solve the problem, we set up a proportion, 3/8 = x/240. Solving for 'x', we find that 90 out of 240 band members would prefer listening to jazz music, so the correct answer is B (90).

This problem concerns proportions. In the survey, it is stated that 3 out of 8 band members preferred listening to jazz. To find out how many out of 240 would prefer jazz, we set up and solve a proportion. Our proportion is 3/8 = x/240, where 'x' is the number of band members we need to find.

To solve for 'x', we cross-multiply 3*240 = 8x. This gives 720 = 8x. Then divide by 8, and we get x = 90. So, 90 out of 240 band members would prefer listening to jazz music.

Therefore, option B (90) is correct.

Birds need energy for flying, breathing, and digesting food. Because of their high metabolism and active lifestyles, all of these processes are crucial for their survival and require substantial energy.

Birds such as eagles and hawks need energy for a variety of activities essential to their survival. The correct answer to what they need energy for is D) all of the above.

These activities include flying, which is a highly energy-intensive activity requiring strong and efficient flight muscles; breathing, because birds have a unique respiratory system adapted for high levels of oxygen intake to support their active metabolisms; and digesting food, since birds have higher metabolic rates than humans, they need to digest their food quickly and eat often to maintain their energy levels.

The digestive process itself also consumes energy as nutrients from food are transformed into usable energy through biochemical reactions.

Final answer:

Eagles and hawks need energy for flying, breathing, and digesting food. Flying requires significant amounts of oxygen and energy due to the bird's efficient but energy-demanding flight muscles. Breathing and digestion are also energy-consuming processes that support the bird's active metabolism and need for frequent food intake.

Explanation:

Eagles, hawks, and other birds require energy for several key activities which are essential for their survival. The energy needs of birds like eagles and hawks encompass flying, breathing, and digesting food. Flying is an activity that demands a great deal of energy since birds need to be light to fly and have powerful flight muscles, making their digestive systems more rapid compared to humans.

Breathing is another crucial activity where birds have adapted a highly efficient respiratory system that enables them to take in the necessary oxygen to support their high metabolic rates. This is especially important because flying consumes a tremendous amount of energy, and birds need to eat often to maintain energy levels due to their quick digestion.

Lastly, digesting food also requires energy, as digestion is the process of breaking down food and transforming nutrients into energy through a series of biochemical reactions. Because birds digest their food quickly, they need to eat greater amounts of food more frequently to meet their high energy demands, which are raised even higher because birds have smaller surfaces to lose heat than humans.
