Answer:

177 hits

Step-by-step explanation:

Let [tex]x[/tex] = number of baseball games

Let [tex]y[/tex] = number of hits

(30, 25) = [tex](x_1,y_1)[/tex]

(100, 165) = [tex](x_2,y_2)[/tex]

Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{165-25}{100-30} =2[/tex]

Using the point-slope formula to create an equation:

[tex]y-y_1=m(x-x_1)\\\\\implies y-25=2(x-30)\\\\\implies y=2x-35[/tex]

Now substitute [tex]x = 106[/tex] into the equation and solve for [tex]y[/tex]:

[tex]\implies y=(2 \times 106)-35=177[/tex]

Therefore, the number of hits Bryce would have after 106 games is 177

Take 2 points

Slope:-

[tex]\\ \rm\hookrightarrow m=\dfrac{165-25}{100-30}[/tex]

[tex]\\ \rm\hookrightarrow m=\dfrac{140}{70}=2[/tex]

Equation in point slope form

[tex]\\ \rm\hookrightarrow y-25=2(x-30)[/tex]

[tex]\\ \rm\hookrightarrow y-25=2x-60[/tex]

[tex]\\ \rm\hookrightarrow 2x-y-35=0[/tex]

[tex]\\ \rm\hookrightarrow y=2x-35[/tex]

[tex]\\ \rm\hookrightarrow y=2(106)-35=212-35=177[/tex]

1) we calculate the volume of the first carton:

volume=length x width x height

volume=3 ft * 2 ft * 2 ft=12 ft³

Therefore:

A machine can fill 12 ft³ in 3 seconds.

2) we calculate the volume of the second carton.

volume=length x width x heigth

volume=4 ft * 5 ft * 6 ft=120 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

12 ft³---------------------3 seconds

120 ft³--------------------      x

x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.

answer: 30 seconds.

Answer:

She has 4 quarters, 13 dimes, and 10 nickels in her purse

Step-by-step explanation:

Let q be the amount of quarters, d be the amount of dimes, and n be the amount of nickels she has in her purse. We can use this to set up a system of equations:

25q+10d+5n=280

This is because a quarter is 25 cents, a dime is 10 cents, and a nickel is 5 cents. We also have to convert $2.80 to cents since all our other values are in cents.

d=q+9

She has 9 more dimes than quarters

n=q+6

She has 6 more nickels than quarters

We can solve this system using substitution (substitute q+9 for d and q+6 for n)

25q+10(q+9)+5(q+6)=280

25q+10(q)+10(9)+5(q)+5(6)=280

25q+10q+90+5q+30=280

40q+120=280

Subtract 120 from both sides

40q=160

Divide both sides by 40

q=4

Now we plug this back into the other equations to find the amount of nickels and dimes

d=q+9=4+9=13

n=q+6=4+6=10

She has 4 quarters, 13 dimes, and 10 nickels in her purse

Step-by-step explanation:

Given the following question:

Like terms are terms with the same variables. In this case "2m and 3m" are like terms, since they both have the same variable which is m. Which means, we would rewrite the equation as so when trying to solve:

Answer:

21%

Step-by-step explanation:

I think this id right but not 100% sure. I made N a random number (5 in my case) then squared it to make it 25. That means M is 25. So if we increase N by 10 percent (.5) it is 5.5 x 5.5 = 30.25. Then i found the difference between the two (5.25) and found the percentage difference (21%). Basically divided 5.25 by 25 and that is the answer. Hope this is right!!!!

Answer:

x+6 < 19

5x < 20

x < 8

Step-by-step explanation:

To solve this problem, you have to plug in numbers for every statement to see if it is true or not. You know that x is a number less than 4, so we can use 3 as an example.

x-2 > 2 | ❌

This can be rewritten as 3-2 > 2 (since we are plugging in 3, any number less than 4 works)

That is equal to 1 > 2, which is not correct. One is not larger than two.

x+6 < 19 | ✅

This can be rewritten as 3+6 < 19 (for the same reason as above)

That is equal to 9 < 19. 19 is greater than 9, so this is correct.

x < 2 | ❌

This can be rewritten as 3-2 > 2.

That is equal to 1 > 2, which is wrong.

5x < 20 | ✅

This can be rewritten as 5 x 3 < 20

That is equal to 15 < 20, which is correct. 15 is less than 20.

x < 8 | ✅

This can be rewritten as 3 < 8.

3 is less than 8, so this is correct.

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

Explanation:

Order doesn't matter when it comes to committees without rankings. Each person on the committee is of equal rank to anyone else. This means we'll use a combination instead of a permutation.

We have 8 men and 3 seats to fill for the men. Plug n = 8 and r = 3 into the nCr combination formula

n C r = (n!)/(r!(n-r)!)

8 C 3 = (8!)/(3!*(8-3)!)

8 C 3 = (8!)/(3!*5!)

8 C 3 = (8*7*6*5*4*3*2*1)/((3*2*1)*(5*4*3*2*1))

8 C 3 = (40320)/((6)*(120))

8 C 3 = (40320)/(720)

8 C 3 = 56

This means there are 56 ways to select the three men from a pool of eight.

Through similar steps, you should plug n = 7 and r = 3 into the nCr combination formula to get 7 C 3 = 35. This means there are 35 ways to pick the three women from a pool of seven.

Overall, there are 56*35 = 1960 ways to select the entire committee of 3 men and 3 women (from a pool of 8 men and 7 women).

Answer:

B)   y = 9

Step-by-step explanation:

Equation of a line in slope-intercept form:  y = mx + b

(where m is the slope (gradient) and b is the y-intercept)

If the line is parallel to the x-axis, the slope is zero.

Therefore, y = (0)x + b

⇒ y = b

We are told that the line passes through point (-1, 9).  Therefore, the y-intercept is 9.

So the equation of the line is:  y = 9

Answer:

D) $247.90

Step-by-step explanation:

[tex] \underline{\sf{y = 2.44x + 3.90}}[/tex]

y is the dependent function whereas x is the independent function.

(What does this mean?)

The values of y depend on the values of x, I.e., any change in the value of x causes a change in the value of y, meanwhile, the opposite doesn't happen.

The cost to print the invitation depends on the number of invitations, for real.

The question asks us to find the cost of printing 100 invitations.

Substituting x for 100:

y = (2.44 × 100) + 3.90

y = 244 + 3.90

y = 247.90

The value of y obtained for x = 100 is the cost of printing 100 invitations – $ 247.90
