A line of a slope 1/4 and passes through the point (0.2,4/5)
Find the value of b, the y-intercept.

The value of w is 38400 when the value of c is 6 as per the concept of a proportional relationship.

Given:

We have to find the value of w at c = 6.

If c = 6, then the value of a becomes a = 48 times (6 divided by 3)

Therefore, the value of a can be evaluated as,

a = 48 x 6/3

a = 48 x 3

a = 144

To find the value of w, rearrange the value of 'a' in the multiple of 9.

For that, divide 144 by 9.

144/9 = 16.

Now, multiply 16 by 2400.

The final value of w = 2400 x 16

w = 38400

According to the information, it can be inferred that the correct inequality is Mallory > Eva (option D).

To identify who is closer to the surface of the water we must read the distance that each of the characters is.

In this case, the person closest to the surface is Eva, who is 5 feet from the surface.

Now we must identify which inequality corresponds to reality. In this case the inequality that is correct is:

Answer:

42 times

Step-by-step explanation:

Here,

4 hits = 7 times

1 hits= 7/4 times

24 hits = 7/4 × 24

= 42 times.

The number of times that the baseball player makes the hit if he hit 24 hits is 42 times, which is an option (a).

Given that:

A baseball player makes 4 hits every 7 times at bat.

It is required to find the number of times that the player hits if he hit 24 hits.

Number of times that 4 hits are made = 7

Number of times that 1 hit is made = 7/4

So, the number of times that 24 hits are made can be found by the following formula.

Using the proportional concept, the number of times, N, is:

[tex]N=\frac{7}{4} \times 24[/tex]

   [tex]=7\times6[/tex]

   [tex]=42[/tex]

The rocket will take 2 seconds for the rocket to hit the ground.

We have,

To find the time it takes for the rocket to hit the ground, we need to determine when the height, h, becomes zero (since the ground is at height zero).

Given the equation for the height of the rocket at time t:

h = -4.9t² + 9.1t + 1.4, we can set h to zero and solve for t:

0 = -4.9t² + 9.1t + 1.4

This is a quadratic equation in the form of at² + bt + c = 0,

where a = -4.9, b = 9.1, and c = 1.4.

To solve for t, we can use the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

Substituting the values:

t = (-(9.1) ± √((9.1)² - 4(-4.9)(1.4))) / 2(-4.9)

t = (-9.1 ± √(82.81 + 27.44)) / (-9.8)

t = (-9.1 ± √110.25) / (-9.8)

Now, we have two possible solutions for t:

t₁ = (-9.1 + √110.25) / (-9.8)

t₂ = (-9.1 - √110.25) / (-9.8)

Calculating these values:

t₁ ≈ -0.143

t₂ ≈ 2

Since time cannot be negative, the only meaningful solution is t₂ ≈ 2 seconds.

Thus,

The rocket will take 2 seconds for the rocket to hit the ground.

=====================================================

Explanation:

Apply the difference of squares rule

x² - 4y² = 13

x² - (2y)² = 13

(x - 2y)(x + 2y) = 13

Since x and y are positive integers, this means x-2y and x+2y are both integers as well.

The value 13 is prime. Its only factors are 1 and 13

Since the above equation shows 13 factoring into x-2y and x+2y, then we have two cases:

----------------

Let's consider case A

We have this system of equations

[tex]\begin{cases}x-2y = 1\\x+2y = 13\end{cases}[/tex]

Add the equations straight down

Therefore we have 2x = 14 solve to x = 7

From here, plug this into either equation to solve for y

x-2y = 1

7 - 2y = 1

-2y = 1-7

-2y = -6

y = -6/(-2)

y = 3

You should get the same result if you used x+2y = 13

----------------

Since we've found that x = 7 and y = 3, notice how case B is not possible

Example:  x-2y = 13 becomes 7-2(3) = 13 which is false.

Also, x+2y = 1 would turn into 7+2(3) = 1 which is also false.

-----------------

Let's check those x and y values in the original equation

x² - 4y² = 13

7² - 4*(3)² = 13

49 - 4(9) = 13

49 - 36 = 13

13 = 13

Step-by-step explanation:

An equilateral triangle is a triangle that has all same 3 measurements of 60°, and since all measurements are same, all sides are also equal too.

Hence, there'll be 3 sides that are 10 units. Since the base is divided into half, each will be 5 for base.

Then apply Pythagoras Theorem where states that:

[tex]\displaystyle{c=\sqrt{a^2+b^2}}[/tex]  or [tex]\displaystyle{c^2=a^2+b^2}[/tex]

where c is hypotenuse, a and b can be defined either adjacent or opposite.

We know that our adjacent is 5 units, opposite is h unit(s) and hypotenuse is 10 units. Apply the theorem:

[tex]\displaystyle{10^2=h^2+5^2}[/tex]

Solve the equation for h-term:

[tex]\displaystyle{100=h^2+25}\\\\\displaystyle{100-25=h^2}\\\\\displaystyle{75=h^2}\\\\\displaystyle{h=5\sqrt{3} }[/tex]

a) Call-more is cheaper

b) 60 minutes

Step-by-step explanation:

Call-More: C = 0.40t + 25

Talk-Now:  C = 0.15t + 40

a) Substitute t =  50 minutes in the above equations.

Call-More:

         C = 0.40*50 + 25

            = 20 + 25

        C = 45

 Talk-Now:

          C = 0.15*50 + 40

              = 7.5 + 40

          C  = 47.40

Company Call-more is cheaper than Talk-now.

b) We have to find the conditions under what condition the two companies charge the same.

    Charge of company Call-more = charge of company Talk-now.

                  0.40t + 25 = 0.15t + 40

                            0.40t = 0.15t + 40 -25

                            0.40t = 0.15t + 15

                 0.40t - 0.15t = 15

                             0.25t = 15

                                     [tex]\sf t = \dfrac{15}{0.25}\\\\ t = \dfrac{15*100}{25}\\\\[/tex]

The compound inequality which represents the number of ounces of clay is c≤4.5 or c≥12.

Given ELISA uses no more than 4.5 ounces of clay and to make a large vase, she uses at least 12 ounces of clay.

Let c denote the wide variety of oz of clay that Elisa makes use of to make one vase of both length.

The words "no more than" implies "much less than or equals to".

So, for a small vase c must be less than or equal to 4.5 ounce, which gives

c≤4.5       ...(1)

And to make a huge vase, she makes use of as a minimum 12 oz of clay.

The word "at least" implies "extra than or equals to"

So, for a large vase c must be more than or equal to 12 ounce, which gives

c≥12         ...(2)

By combining equations (1) and (2), we get
