I have to say 25% because 25% of 600 is 150. 600+150=750. So I hope this help!!!

The solution is, the percent of error, rounded to the nearest percent is 25%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Answers

$\qquad \tt \rightarrow \: Acceleration_{dog} = 0$

____________________________________

$ \large \tt Solution \: : $

A dog is moving at a constant speed of 8 m/s, that concludes that there's no change in its speed with respect to time.

And Acceleration is define as rate of change in velocity, but since velocity/speed is constant. change in velocity = 0

Henceforth, Acceleration of dog is 0 as well.

Answered by : ❝ AǫᴜᴀWɪᴢ ❞

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Part 1

Acceleration means "change in speed (which is also known as velocity, V, in physics) per a specific amount of time.

Part 1 is Successfully completed!

↪

Part 2Our Dog Problem

Now let's focus on finding the acceleration of the dog.

Like I said above, $\sf Acceleration=change\;in\;speed\;per\;a\;specific\;amount\;of\;time$

Well, we are provided with the information that the dog's speed is constant. This means that it doesn't change. So the dog keeps on moving at a speed of 8 m/s. This means that its speed doesn't change, so the change in speed is 0. And this means that its acceleration is 0.

Voila! There's our answer, cheers! (:

mr. g finds a house for $155,000. He meets with the bank and finds a 30 year simple interest mortgage. If mr g accepts the mortgage, he would pay $232,500 in simple interest over the life of his loan. How much is his interest rate?

Answers

The interest rate on the mortgage is 5 %

What is the interest rate

Let's begin by using the formula for simple interest:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed), r is the interest rate, and t is the time (in years).

For Mr. G's mortgage, we know that the principal is $155,000 and the time is 30 years. We can use this information to solve for the interest rate, r.

First, we need to calculate the total amount that Mr. G will pay over the life of the loan (the principal plus the interest):

A = P + I

where A is the total amount, P is the principal, and I is the interest.

We know that Mr. G will pay $232,500 in interest, so we can solve for A:

Let's begin by using the formula for simple interest:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed), r is the interest rate, and t is the time (in years).

For Mr. G's mortgage, we know that the principal is $155,000 and the time is 30 years. We can use this information to solve for the interest rate, r.

First, we need to calculate the total amount that Mr. G will pay over the life of the loan (the principal plus the interest):

A = P + I

where A is the total amount, P is the principal, and I is the interest.

We know that Mr. G will pay $232,500 in interest, so we can solve for A:

A = P + I

A = $155,000 + $232,500

A = $387,500

Now we can use the formula for simple interest to solve for the interest rate, r:

I = P * r * t

$232,500 = $155,000 * r * 30

r = $232,500 / ($155,000 * 30)

r = 0.05 or 5%

Therefore, Mr. G's interest rate is 5%.

c. How many ways are there to select a handful of 20 jellybeans that contains at least 3 red?
d. How many ways are there to select a handful of 20 jellybeans that contains at least 3 red and at most 2 orange?

Answers

Answer:

$\left \{ {{80} \atop {20}} \} * \left \{ {{60} \atop {20}} \} * \left \{ {{40} \atop {20}} \} * \left \{ {{20} \atop {20}} \}$

$\left \{ {{20+4-1} \atop {4-1}} \} = \left \{ {{23} \atop {3}} \}$

= $\left \{ {{17+4+1} \atop {4-1}} \} = \left \{ {{20} \atop {3}} \}$

= $\left \{ {{20} \atop {3}} \} - \left \{ {{17} \atop {3}} \}$

Step-by-step explanation:

A) How many ways can you put all Jellybeans in a row

Total number of Jellybeans = 80

The first jellybeans = 20 yellow , second is 20 orange jellybeans , third is 20 red jellybeans , fourth is 20 green jellybeans

Therefore the number of ways the Jellybeans can be put in a row is :

$\left \{ {{80} \atop {20}} \} * \left \{ {{60} \atop {20}} \} * \left \{ {{40} \atop {20}} \} * \left \{ {{20} \atop {20}} \}$

B) How many ways are there to select a handful of 20 jellybeans

lets assume:

yellow jellybeans = a , orange jellybeans = b , red jellybeans = c , green jellybeans = d

a + b + c + d = 20

This is the number Non-negative integer solutions

= $\left \{ {{20+4-1} \atop {4-1}} \} = \left \{ {{23} \atop {3}} \}$

C) This is also the number of Non-negative integer solutions but in this case the value of C ≥ 3

hence the number of ways to select a handful of 20 jellybeans that contains at least 3 red

= $\left \{ {{17+4+1} \atop {4-1}} \} = \left \{ {{20} \atop {3}} \}$

D) In this case the value of C ≥ 3 and B ≤ 2

Hence the number of ways to select a handful of 20 jellybeans that contains at least 3 red and at most 2 orange

= $\left \{ {{20} \atop {3}} \} - \left \{ {{17} \atop {3}} \}$

The area of the circular base of a cone is 16π cm², and the slant height of the cone is 4 times the radius of the cone.

What is the approximate lateral area of the cone?

Answers

The approximate lateral area of the cone is equal to 200.96 cm².

How to calculate the lateral area of the cone?

Mathematically, the lateral area of a cone can be calculated by using this mathematical expression:

Lateral surface area of a cone, LSA = πrl or πr√(r^2 + h^2)

Where

l represents the slant height of the cone.r represents the radius of the cone.h represents the height of the cone.

How to calculate the area of a circle?

Mathematically, the area of a circle can be calculated by using this formula:

Area of a circular base = πr²

16π = πr²

Radius, r = √16

Radius, r = 4 cm.

Substituting the given parameters into the lateral area of a cone formula, we have the following;

Lateral surface area of a cone, LSA = πrl = πr4(r)

Lateral surface area of a cone, LSA = 3.14 × 4 × 16

g A plane flying with a constant speed of 29 km/min passes over a ground radar station at an altitude of 15 km and climbs at an angle of 45 degrees. At what rate is the distance from the plane to the radar station increasing 5 minutes later

Answers

Answer:

At 28.93 km/min is the distance from the plane to the radar station increasing 5 minutes later

Step-by-step explanation:

Refer the attached figure

$\angle A =45+90=135^{\circ}$

We are given A plane flying with a constant speed of 29 km/min passes over a ground radar station at an altitude of 15 km

$\frac{dy}{dt}=29$

x=15 km

We will use cosine law

$z^2=x^2+y^2-2xy Cos A\\z^2=15^2+y^2-30y Cos A\\z^2=225+y^2-30y Cos A$----1

Differentiating

$2z\frac{dz}{dt}=2y\frac{dy}{dt}-30Cos(135^{\circ})\frac{dy}{dt}$----2

$\frac{dy}{dt}=29\\y=5 \times 29 =145$

Substitute values in 1

$z^2=225+(145)^2-30(145) Cos (135)\\z=\sqrt{225+(145)^2-30(145) Cos (135)}$

z=155.96 km

Substitute values in 2

So, $2(155.96)\frac{dz}{dt}=2(145)(29)-30Cos(135^{\circ})(29)$

$\frac{dz}{dt}=\frac{2(145)(29)-30Cos(135^{\circ})(29)}{2(155.96)}$

$\frac{dz}{dt}=28.93$

Hence At 28.93 km/min is the distance from the plane to the radar station increasing 5 minutes later

g A plane flying with a constant speed of 29 km/min passes over a ground radar station at an altitude

The rate at which the distance from the plane to the radar station is increasing 5 minutes later is; 28.85 km/min

Since the train passes at an altitude of 15 km.

Let us say a = 15 km

Then it climbs at an angle of 45°

Plane is flying at a speed of 29 km/min

Thus, in t minutes, it will have flown a distance of 29t km

Now, the distance of the plane from the radar station t minutes later is gotten by Pythagoras theorem as;

x(t) = √[(29t)² + (15²)]

x(t) = √(841t² + 225)

x'(t) = dx/dt = 841t/(√(841t² + 225))

After t = 5 minutes, we have;

x'(5) = (841 × 5)/(√((841 * 5²) + 225))

x'(t) = 4205/145.7738

x'(t) = 28.85 km/min
