Answer:

x=$150,000

4th person invested $550,000

Step-by-step explanation:

100,000+x+2x+(100,000+x+2x)=1,100,000

200,000+6x=1,100,000

6x=900,000

x=150,000

The investment of the fourth person is 100,000+3x

=100,000+450,000

=$550,000

The amount invested by the fourth person was $550,000.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Given that a person invested $100,000. Two others invested in the ratio x:2x and the fourth person invested an amount equal to the other three investors combined.

We have to determine an expression for the amount invested by the fourth person.

The total investment = $1,100,000.

So an expression for the amount invested by all people as:

⇒ 100,000 + x + 2x + (100,000+x+2x) = 1,100,000

⇒ 200,000 + 6x = 1,100,000

⇒ 6x = 900,000

⇒ x = 150,000

So the investment of the fourth person as

⇒ 100,000 + 3x

⇒ 100,000 + 450,000

⇒ $550,000

Answer:

Step-by-step explanation:

Are you asking for a pattern? The answer is 16

4+4=8

8+4=12

12+4=16

The given sequence 4, 8, 12, ... is an arithmetic expression thus the next term will be 16.

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

The arithmetic progression has broader use in mathematics for example sum of natural numbers.

As per the given sequence,

4,8,12,..

Now, 8 - 4 = 4

12 - 8 = 4

Since the common difference is the same thus it will be an arithmetic expression.

The nth term of AP is given as,

a(n) = a + (n - 1)d

Here, a is the first term, and d is a common difference.

The fourth term of the given sequence is,

a(4) = 4 + (4 - 1)4

⇒ 4 + 12 = 16

Hence "The given sequence 4, 8, 12, ... is an arithmetic expression thus the next term will be 16".

Answer:

The smaller angle is 18 degrees

The larger angle is 72 degrees

Step-by-step explanation:

x = smaller angle

y = larger angle

y = 4x ---> one angle is 4 times larger than other one.

y + x = 90 ----> the sum of complementary angles is 90 degrees

4x + x = 90 ----> plug in 4x for the larger angle (y) and then solve

5x = 90

x = 18 ----> the smaller angle is 18 degrees

y = 90 - 18

y = 72 ----> the larger angle is 72 degrees

The smaller angle is 18.

The complementary angle is the angle that adds up to 90 degrees always, so when we say that two angles are complementary it means that the sum of the angle or the combined angle is equal to ninety degrees.

The larger angle is 4 times the smaller angle so let the smaller angle be 'x' and the larger angle be 4x.

Hence the sum of both the angle is 90 degrees from the definition of complementary

so 4x+x=90, 5x = 90

dividing the equation by 5

x = 18

Hence the smaller angle is 18 degrees

Answer: 36 3/14 miles per hour

Step-by-step explanation:

multiply the speed of a human (5 4/7) by 6 1/2 or 6.5 and you get your answer

To find the fish's speed, convert the mixed numbers 5 4/7 and 6 1/2 to improper fractions and multiply them. The result, 507/14, converts back to a mixed number as approximately 36.21 miles per hour.

To solve this question, we need to multiply the person's swimming speed with the mentioned relative speed of the fish. A person can swim at a speed of 5 4/7 miles per hour, and since the fish can swim 6 1/2 times faster, we multiply 5 4/7 by 6 1/2.

The first step is to convert these mixed numbers to improper fractions. 5 4/7 becomes 39/7 and 6 1/2 becomes 13/2.

Multiplication of fractions involves multiplying the numerators together to get the new numerator and the denominators together to get the new denominator. So the multiplication (39/7)*(13/2) leads to a result of 507/14.

This can be now converted back to a mixed number, giving us an approximate answer of 36.21. Therefore, the fish swims at a speed of approximately 36.21 miles per hour.

Answer: 2/7

Step-by-step explanation: To simplify the fraction 14/49, we need to find the greatest common factor of 49 and 7 and we can divide our fraction by it.

In this case, the greatest common factor of 14 and 49 is 7 so we can divide both our numerator and denominator by 7.

Therefore, 14/49 as a simplified fraction is 2/7.

It travels for 1 h, then stops for 1 h, and finally travels again for 3 h.  

Step-by-step explanation:

The sloped parts of the graph are where the car is moving.

For example, in the first hour the distance travelled changes from zero to 12 mi.

The horizontal part of the graph is where the car is stopped.

For example, between hours 1 and 2, the distance travelled stays the same at 12 mi.

Answer:

C. Paige's soccer ball.

Step-by-step explanation:

When you graph y = 3x^2 + 6x + 3, you can see that the max of the parabola is around 6. This is lower compared to Paige's soccer ball's max height shown in the image.

Answer:

Step-by-step explanation:

To solve this problem, we just need to graph Viola's function to know the altitude she reached, and then compare it with Paige's altitude.

So, we know that Viola's function is [tex]y=-3x^{2}+6x+3[/tex], as an extra solution, we can calculate the vertex of this quadratic function, that will give us Viola's max altitude.

[tex]V(v_{x};v_{y})\\V(\frac{-b}{2a};f(v_{x} ))[/tex]

Where b and a are from the general quadratic function: [tex]y=ax^{2} +bx+c[/tex].

So, in this case, a = -3; b = 6. Replacing this values, we find the vertex:

[tex]V(\frac{-b}{2a};f(v_{x} ))[/tex]

[tex]v_{x}= \frac{-b}{2a}=\frac{-6}{2(-3)}=1[/tex]

Then, we use the function to calculate the vertical coordinate of the vertex:

[tex]v_{y}=f(1)=-3(1)^{2}+6(1)+3=-3+6+3=6[/tex]

Therefore, the max altitude reached by Viola is 6 meters.

Now, from the graph, we observe that Paige's max altitude is around 7.5 meters.

Therefore, Paige reached the higher height. The answer is C.

Answer:

x = -8

QR = 6

PR = 9

Step-by-step explanation:

Alrighty, this one has a lot of steps. We have to think about this logically.

The length of PR is x + 17, and the length of PQ is 3, and the length of QR is 2x + 22.

The length of PR could also be written as the length of PQ + QR, which gives us the formula PR = PQ + QR. This allows us to put all our information into one formula to solve for x.

PR = PQ + QR

x + 17 = 3 + 2x + 22

17 - 3 - 22 = 2x - x

-8 = x

so x = -8

Now we can use that x and plug it into the other two formulas:

QR = 2x + 22

QR = 2(-8) + 22

QR = -16 + 22

QR = 6

And now we plug x into PR:

PR = x + 17

PR = -8 + 17

PR = 9

Alternatively, we can use our other formula, PR = 3 + QR, which gets us the same answer:

PR = 3 + QR

PR = 3 + 6

PR = 9

Answer:x=-36

Step-by-step explanation:

First step: Simplify both sides of the equation by

x=1 ,so you put 1/8 and move x to the side like this 1/8x

Now you got 1/8x+1/2=-4

Step 2: Subtract 1/2 to both sides because it's the smallest constant/number

1/2-1/2=0 and -4-1/2=-9/2

-4 subtracted from 1/2 ,you put a 1 under -4, it would be like this -4/1 subtracted from 1/2

I do the butter-fly method which would be -4*2-1*1 because when you put the fractions like this -4/1-1/2 on paper then you would see why

and you multiply the denominators(bottom), so 1*2=2,and -8-1 equals -9 because -8 is larger than postive 1.

so now we have -9/2

Last step is to multiply by 8 on both sides to get rid of the 8 on the other side(left side) so x will be alone,so 8*-9/2=-36

First you will get -72/2 when you divide it you get -36

Answer:

The ball will take 4.05 seconds to hit the ground.

Step-by-step explanation:

we have

[tex]h=-16t^{2}+64t+3[/tex]

This is a quadratic equation (vertical parabola) open down

The vertex is a maximum

we know that

The ball hit the ground when h=0

Solve the quadratic equation

For h=0

[tex]-16t^{2}+64t+3=0[/tex]

The formula to solve a quadratic equation of the form

[tex]at^{2} +bt+c=0[/tex] is equal to

[tex]t=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]-16t^{2}+64t+3=0[/tex]  

so

[tex]a=-16\\b=64\\c=3[/tex]

substitute in the formula  

[tex]t=\frac{-64(+/-)\sqrt{64^{2}-4(-16)(3)}} {2(-16)}[/tex]

[tex]t=\frac{-64(+/-)\sqrt{4,288}} {-32}[/tex]

[tex]t=\frac{64(-)\sqrt{4,288}} {32}=-0.05\ sec[/tex]  ---> the time cannot be a negative number

[tex]t=\frac{64(+)\sqrt{4,288}} {32}=4.05\ sec[/tex]

therefore

The ball will take 4.05 seconds to hit the ground.
