Answer:

Step-by-step explanation:

Some information is missing. The correct question is:

Theresa has two brothers, Paul and Steve, who are both the same height. Paul says he is 16 inches shorter than 1 1/2 times Theresa's height. Steve says he's 6 inches shorter than 1 1/3 times Theresa's height. If they're both right, how tall is Theresa?

Solution:

Let p represent Paul's height

Let s represent Steve's height

Let t represent Theresa's height

Since Paul and Steve are both of the same height, it means that p = s

Paul says he is 16 inches shorter than 1 1/2 times Theresa's height. It means that

p = 1.5t - 16

Steve says he's 6 inches shorter than 1 1/3 times Theresa's height. It means that

s = 4t/3 - 6

Since p = s, then

p = 4t/3 - 6

Therefore, it means that

1.5t - 16 = 4t/3 - 6

Multiplying through by 3, it becomes

4.5t - 48 = 4t - 18

4.5t - 4t = - 18 + 48

0.5t = 30

t = 30/0.5 = 60 inches

Theresa's height is 60 inches

Answer:

Part A : The expression that represents Paul’s height in inches is

3/2 t - 16

Part B : The expression that represents Steve’s height in inches is

4t/3 - 6

Answer:

y = - 4x + 17

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 1) and (x₂, y₂ ) = (2, 9)

m = [tex]\frac{9-1}{2-4}[/tex] = [tex]\frac{8}{-2}[/tex] = - 4, thus

y = - 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 1) , then

1 = - 16 + c ⇒ c = 1 + 16 = 17

y = - 4x + 17 ← equation of line

b. two complex solutions

c = 17, x={-2+sqrt(13)i, -2-sqrt(13)i}

c. two coincident roots (i.e. one real solution)

c=4, x = {-2}, or x = {-2, -2}

Step-by-step explanation:

Given:

x^2+4x+c =0

a. two (distinct) real solutions.

c = 3

(x+1)(x+3) = 0

x=¨{-1,-3}

b. two complex solutions

c = 17

x^2+4x+17=0

does not have real factors.

x={-2+sqrt(13)i, -2-sqrt(13)i}

c. two coincident roots (i.e. one real solution)

c=4

x^2+4x+4=0 => (x+2)^2 = 0 => perfect square

x = {-2}, or x = {-2, -2}

Answer:

Isosceles, obtuse triangle

Step-by-step explanation:

Step-by-step explanation:

Here, we want to

calculate the amount of time taken to fill the tank given the total amount of water in the tank.

Mathematically, the formula go

use is ;

w= 100 + 55t

540 = 100 + 55t

55t = 540-100

55t = 440

t = 440/55

t = 8

Answer:

The expression represents Ann's membership cost as a function of how many times she brings John along. For t = 5 the cost is 275, for t = 10, the cost is 250 and for t = 20 the cost is 200.

Step-by-step explanation:

The expression "300 - 5*t" represents the cost of Ann's membership plan on the local gym, where "t" is the number of visits John pays Ann. This means that the more times John goes to the gym with Ann, the less is her cost to pay the membership.

For t = 5:

[tex]cost = 300 - 5*t\\cost = 300 - 5*5 = 275[/tex]

For t = 10:

[tex]cost = 300 - 5*t\\cost = 300 - 5*10 = 250[/tex]

For t = 20:

[tex]cost = 300 - 5*t\\cost = 300 - 5*20 = 200[/tex]

Answer:

Step-by-step explanation:

7- 4!= 4*3*2*1=24

8-  10C3 = 10!/(3!*(10!-3!) = 120

9- 7 P3 =7!/(7-3)! = 210

Answer:

B

Step-by-step explanation:

The soccer player has g goals and a assists.

For every goal, he/she gets 2 points and for every assist, he/she earns 1 point. This means that if we multiply g by 2, we get the number of points the player receives from g goals and if we multiply a by 1, we get the number of points the player receives from a assists.

And, that total number of points is equal to 42, so we can write:

2 * g + 1 * a = 42

2g + a = 42

Now, we understand that g and a are the number of goals and assists the player has made, and we also know that the total number of such kicks is 24, so we can write:

g + a = 24

Thus, our system is:

g + a = 24

2g + a = 42

The answer is B.

~ an aesthetics lover

Answer:

The correct answer is B. g + a = 24. 2 g + a = 42

Answer:

The total time taken to reach C = 10 s

The total distance traveled by the body = 29 m

Step-by-step explanation:

Whereby the points are vertically oriented, we have;

v = u + at

Where;

a = Acceleration of the body = -1 m/s²

u = Initial velocity = 3 m/s

v = Final velocity, = 0 m/s at maximum height

t = Time taken

0 = 3 + (-1)× t

t = 3 s

The maximum height S is given as follows;

S = u·t  + 1/2·a·t² = 3×3 + 1/2×(-1)×3² = 4.5 m

Therefore, the total distance, [tex]S_t[/tex], from maximum height to C = 45 + 20 = 24.5 m

The total time is given from the total distance as follows;

[tex]S_t[/tex]  = u[tex]_m[/tex]·t[tex]_t[/tex]  + 1/2·a[tex]_d[/tex]·t[tex]_t[/tex]²

Where;

u[tex]_m[/tex] = Initial velocity from the maximum height = 0 m/s

a[tex]_d[/tex] = Downward acceleration = Opposite sign to upward acceleration = 1 m/s²

24.5  = 0·t[tex]_t[/tex]  + 1/2·(1)·t[tex]_t[/tex]²

49 = t[tex]_t[/tex]²

t[tex]_t[/tex] = √ 49 = 7 s

The total time taken to reach C = Initial time to reach maximum height + Time from maximum height = 3 s + 7 s = 10 s

The total time taken to reach C = 10 s

The total distance traveled by the body = Distance from B to maximum height + Distance from maximum height to C

The total distance traveled by the body = 4.5 m + 24.5 = 29 m.

The total distance traveled by the body = 29 m.

Answer:

3

Step-by-step explanation:

5 x + 2 = 7 x − 4

7x-5x= 2+4

2x= 6

x= 3

Answer:

The value of x in this equation is 3.

Step-by-step explanation:

5x + 2 = 7x - 4

Subtract 7x from both sides of the equation.

-2x + 2 = -4

Subtract 2 from both sides of the equation.

-2x = -6

Divide by -2 on both sides of the equation.

x = 3

Simplifying the expression (x - 2y) + (3x + 4y).

Work:

(x - 2y) + (3x + 4y)

Combine like terms.

x + 3x = 4x

-2y + 4y = 2y

Reform the expression.

4x + 2y

Simplified Expression: 4x + 2y.

Answer:

D; 5pi/3 units

Step-by-step explanation:

Here, we want to find the period of the function;

y = 3/2 cot (3/5x) + 5

By definition, the period of a function is the interval between two matching points in the function.

Let’s say it is the distance between two peaks, crests, etc on a function.

To find the value of the period. We shall standardize the function.

What this means is that we shall be writing the function in the standard form.

The standard form is as follows;

f(x) = A trig(Bx -C) + D

Where trig refers to the accompanying trigonometric function in question.

Comparing this standard form with our question, we can see that;

A is 3/2

B is 3/5

C is 0

D is 5

Now for cot and tan functions, we shall need to divide pi by the absolute value of B

Thus we have; pi divided by 3/5 which gives 5pi/3 units

Answer:

D. 5pi/3, period is the distance between the repetition of a function.

Answer:

Side CA = 7.8

Step-by-step explanation:

Given:

Acute angled [tex]\triangle ABC[/tex].

[tex]\angle B =40^\circ[/tex]

AB = 10

BC = 12

We can use cosine rule here to find the side AC = b

Formula for cosine rule:

[tex]cos B = \dfrac{a^{2}+c^{2}-b^{2}}{2ac}[/tex]

Where  

a is the side opposite to [tex]\angle A[/tex]

b is the side opposite to [tex]\angle B[/tex]

c is the side opposite to [tex]\angle C[/tex]

[tex]cos 40 = \dfrac{12^{2}+10^{2}-b^{2}}{2\times 12\times 10}\\\Rightarrow cos 40 = \dfrac{144+100-b^{2}}{240}\\\Rightarrow 0.77 = \dfrac{244-b^{2}}{240}\\\Rightarrow 244-b^{2} = 0.77 \times 240\\\Rightarrow 244-b^{2} = 183.85\\\Rightarrow 244-183.85 = b^{2}\\\Rightarrow b^2 = 60.15\\\Rightarrow b = 7.76[/tex]

To the nearest tenth b = 7.8

Answer:  tan(14x)

Step-by-step explanation:

Consider the Sum Formula for tan:

[tex]tan(A + B)=\dfrac{tan(A)+tan(B)}{1-tan(A)(tan(B)}\\\\\\tan(9x+5x)=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}\\\\\\\large\boxed{tan(14x)}=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}[/tex]

Answer:

[tex]\tan(4x)[/tex]

Step-by-Step Explanation:

Notice that this resembles the difference identity for tangent. Specifically:

[tex]\displaystyle \tan(\alpha-\beta)=\frac{\tan(\alpha)-\tan(\beta)}{1+\tan(\alpha)\tan(\beta)}[/tex]

So, given our equation, we can pretend that α=9x and β=5x. Therefore:

[tex]\displaystyle \frac{\tan(9x)-\tan(5x)}{1+\tan(9x)\tan(5x)}=\tan(9x-5x)=\tan(4x)[/tex]
