Answer:

Franco has 66 baseball cards.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of baseball cards that Franco has.

y is the number of baseball cards that Juan has.

Franco has 18 fewer baseball cards than Juan.

This means that:

[tex]x = y - 18[/tex]

Also:

[tex]y = x + 18[/tex]

Together they have 150 baseball cards.

This means that:

[tex]x + y = 150[/tex]

Since [tex]y = x + 18[/tex]

[tex]x + x + 18 = 150[/tex]

[tex]2x = 132[/tex]

[tex]x = \frac{132}{2}[/tex]

[tex]x = 66[/tex]

Franco has 66 baseball cards.

Answer:

slope = 1

y-intercept = -3

Step-by-step explanation:

3y = 3x - 9

divide each side by 3

y = x - 3

slope = 1

y-intercept = -3

Answer:

Part A)

784 feet in the air (after five seconds).

Part B)

After 12 seconds.

Step-by-step explanation:

The height h (in feet) of a rocket t seconds after being fired is modeled by the function:

[tex]h(t)=-16t^2+160t+384[/tex]

Part A)

We want to find the rocket's maximum height.

Since our function is a quadratic, the maximum height will occur at its vertex. The vertex of a quadratic is given by:

[tex]\displaystyle \Big(-\frac{b}{2a}\, f\Big(-\frac{b}{2a}\Big)\Big)[/tex]

In this case, a = -16, b = 160, and c = 384.

So, the vertex occurs at:

[tex]\displaystyle t=-\frac{160}{2(-16)}=\frac{160}{32}=5\text{ seconds}[/tex]

The maximum height is reached after five seconds.

Then the maximum height is:

[tex]h(t)_\text{max}=h(5)=-16(5)^2+160(5)+384=784\text{ feet}[/tex]

Part B)

When the rocket reaches the ground, its height h above the ground will be 0. Hence:

[tex]h(t)_\text{ground}=0=-16t^2+160t+384[/tex]

Solve for t. We can first divide both sides by -16:

[tex]t^2-10t-24=0[/tex]

Factor:

[tex](t-12)(t+2)=0[/tex]

Zero Product Property:

[tex]t-12=0\text{ or } t+2=0[/tex]

Solve for each case:

[tex]t=12\text{ or } t=-2[/tex]

Time cannot be negative. Hence, our only solution is:

[tex]t=12\text{ seconds}[/tex]

The rocket reaches the ground 12 seconds after it is fired.

Answer:

D, 94

Step-by-step explanation:

Angles of a triangle add up to 180 degrees.  180 - 29 - 65 = 86 Angles 1 and 2 add up to 180 degrees.  86 = 2  180 - 86 = 94 94 = 1

Answer:

3 x 5 = 15

Step-by-step explanation:

To explain this in short, John has 5 gallons of 3 colors, meaning that 3 x 5 = 15 would be the appropriate equation to finish this question. I hope this helps!

Answer:

750 blocks = 6m long

x blocks = 10m long

750×10 = 6x

7500 = 6x

divide both sides by 6

7500/6 = 6x/6

1250 = x

x = 1250

.

. . 1250 blocks are needed to finish the wall of 10m long

Answer:

Arithmetic sequence with common difference of 3.

Step-by-step explanation:

Arithmetic sequence:

The difference between consecutive terms is always the same, and this difference is called common difference.

Geometric sequence:

The quotient between consecutive terms is always the same, and this quotient is called common ratio.

In this question:

5 - 2 = 8 - 5 = 3

5/2 = 2.5 different of 8/5 = 1.6

This means that it is an arithmetic sequence with common difference of 3.

Caculator

Answer:

Step-by-step explanation:

7a - 4a

a = 8

so

7(8) - 4(8)

56 - 32 = 23

FINALLY! Someone asks for a step-by-step! TYSM!

Since a=8, we ae going to replace the a variables with 8.

7(8)-4(8)

7x8=56

4x8=32.

Now we subtract.

56-32=24.
