Answers

Answer 1

Answer:

  4

Step-by-step explanation:

The proportional relationship can be described by the equation ...

  [tex]f=\dfrac{k}{\sqrt{g}}[/tex]

We can fill in the given values to find k:

  15 = k/√144 = k/12

  15·12 = k = 180 . . . . . . multiply by 12

Then for f = 90, we have ...

  90 = 180/√g

  1/2 = 1/√g . . . divide by 180; next multiply by 2√g and square both sides

  g == 4 . . . . the value of g when f=90

b. At the circus, three adult tickets and five child tickets cost $51, and five adult tickets
and two child tickets cost $47. Which system of linear equations below can be used to
determine the price of each ticket?
Let x represent the cost of an adult ticket, and let y represent the cost of a child ticket.

Answers

Answer: x = $7, y = $6

Step-by-step explanation:

Let x be the cost of an adult ticket

Let y be the cost of a children's ticket

Translate these sentences to algebra:

At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51

Five adult tickets and two child tickets cost $47: 5x + 2y = 47

Now we have two equations. Let's use substitution to solve.

3x + 5y = 51

3x = 51 - 5y

.: x = 17 - 5y/3

Now substitute this value of x into the second equation to find the numerical value of y:

5(17 - 5y/3) + 2y = 47

85 - 25y/3 + 2y = 47

-19y/3 = -38

-19y = -114

.: y = 6

Now find x:

x = 17 - 5y/3

x = 17 - 10

.: x = 7

So an adult ticket costs $7, and a child ticket costs $6 :)

one number is three times another number, and their sum is -10. what is the smaller of the two numbers?

Answers

Let the smaller number be x .

Then the larger number = 3x

Their sum = -10

This can be written in an equation as :-

[tex]x + 3x = - 10[/tex]

[tex]4x = - 10[/tex]

[tex]x = \frac{ - 10}{ \: \: \: 4} [/tex]

[tex]x = - 2.5[/tex]

Which means :-

The value of the first number = -2.5

The value of the second number = -2.5 × 3 = -7.5

Therefore , the smaller of the two numbers is = -7.5

Answer:

let a + b = -10

where a = 3b

substitute a into the equation: a + b = -10

3b + b = -10

b = -10 / 4

b = -2.5

a = 3b

a = 3(-2.5)

a = -7.5

check:

a + b = -10

-7.5 + (-2.5) = 10

-10 = 10

4 points in each of 5 games, 5 points in each of 2 games, 10 points in each of
3 games, 24 points in 1 game, and did not score in 3 games. What is the mean
number of points Phoebe scored per game?

Answers

Answer:

ok so first we have to find the total amount

4*5=20

5*2=10

10*3=30

24*1=24

0*3=0

now lets add up the total

20+10=30

30+24=74

104

then we have to divide by the amount of games to find the average or mean

104/14=7.43(aprox)

so she scores a average of about 7 points a game

Arlington High School recently installed a new black-box theatre for local productions. They only had
room for 14 rows of seats, where the number of seats in each row constitutes an arithmetic sequence starting
with eight seats and increasing by two seats per row thereafter. How many seats are in the new black-box
theatre? Show the calculations that lead to your answer.

Answers

Answer: ANSWER*0.15 (15% is 15/100 or 0.15)

Step-by-step explanation:

An arithmetic sequence is a sequence where the difference between each consecutive term is the same.

The number of seats in the new black box is 294.

What is an arithmetic sequence?

It is a sequence where the difference between each consecutive term is the same.

Example:

2, 4, 6, 8 is an arithmetic sequence.

We have,

Number of rows = 14

n = 14

a = 8.

d = 2

So,

The number of seats in the 14 rows is,

8, 10, 12, 14,.........

Now,

The sum of the arithmetic sequence.

= n/2 [2a + (n - 1)d ]

The number of seats in the new black box.

= 14/2 [ 2x8 + (14 - 1)2 ]

= 7 [ 16 + 26 ]

= 7 x 42

= 294

Thus,

The number of seats in the new black box is 294.

Find the equation of the tangent line to the curve y= 2x2 + x-1 at the point (5, 54).

Answers

Answer: y-54=21(x-5) or y=21x-51

Step-by-step explanation:

To find the equation of the tangent line, we first want to find the derivative of the equation.

f(x)=2x²+x-1           [Power Rule]

f'(x)=4x+1

Now that we have the derivative, we use (5,54) to find the slope.

f'(5)=4(5)+1            [multiply]

f'(5)=20+1              [add]

f'(5)=21

With our slope, we can plug it into point-slope form.

y-54=21(x-5)

We can also convert this to slope-intercept form.

y-54=21(x-5)          [distribute]

y-54=21x-105        [add both sides by 54]

y=21x-51

Now, we know the tangent line is y-54=21(x-5) or y=21x-51.

What is the equation of the given line in the point-slope form?

(A) 3 (B) 4 (C) 12 (D) 36

Answers

Answer:

(D) 36

Step-by-step explanation:

0.5%  = 0.5/100  =  0.005

It is given that the population (215) is predicted to increase by 0.5%. To know the value after increment, 215 has to be multiplied by (1 + 0.005) or 1.005.

In the equation P  =  215(1.005)t/3, the value of t/3 has to be equal to 1 for 0.5% increase.

t/3  =  1

t  =  3 years

Convert years to months.

Hope it helped!

[tex]\huge\boxed{Thanks,\;Plip.}[/tex]

We want to find and solve an equation that tells us the number of pounds of raisins that we need to add to a mixture to get to a desired price.

We will see that we need to add 3 pounds of raisins.

We know that:

Granola costs $3.25 per lbRaisins cost $6.50 per lb.

If we mix M pounds of raisins with 10 pounds of granola, the total mass will be:

M + 10

The price of this will be:

M*$6.50 + (10)*$3.25

And we want the price of this mixture to e $4.00 per pound, then we have:

M*$6.50 + (10)*$3.25 = (M + 10)*$4.00

Now we need to solve the above equation for M.

M*$6.50 + $32.50 = M*$4.00 + $40.00

M*$6.50 - M*$4.00 = $40.00 - $32.50

M*($6.50 - $4.00) = $7.50

M*$2.50 = $7.50

M = ($7.50)/($2.50) = 3

M = 3

This means that we need to add 3 pounds of raisins.

What is the equation of the line that is parallel to the line defined by the equation y = 2x + 4 and goes through the point (3, 2)?

Answers

Step-by-step explanation:

Hey there!

Given;

y = 2x + 4..........(i)

The point is; (3,2). The equation of line which passes through this point is;

(y-y1) = m2(x-x1)

(y-2)= m2(x-3)........(ii)

From equation (i).

y = 2x+4

Comparing the equation with y = mx+c, we get;

Slope (m1)= 2

As per the condition of parallel lines, (m1=m2).

Therefore, m2= 2.

Now, keeping the slope of m1 in eqaution (ii)

(y-2)= 2(x-3)

y - 2 = 2x - 6

y = 2x -4

Therefore, the equation is y = 2x - 4.
