Step-by-step explanation:

Let x = number of months

Let y = total cost of renting a saxophone

Manny's Music Rental:  y = 40 + 25x

Sid's Saxophones:   y = 25 + 30x

Answer:20

Step-by-step explanation: Add all the marbles up = 100 divided by 2 = 50 so then divide the purple marble by 2 =20.

Tanya should expect to pull a purple marble for 8 times.

The experimental probability of an event is based on the number of times the event has occurred during the experiment and the total number of times the experiment was conducted.

Given that, Tanya performed an experiment in which she randomly pulled a marble from a bag,

Out of the experiment that Tanya performed, we can get an experimental probability.

This experimental probability is given by the quotient between the frequency for each color, and the total number of trials.

The total number of trials is:

N = 25 + 35 + 40 = 100

And on 40 of these, she got a purple marble, then the experimental probability of getting a purple marble is:

p = 40/100 = 0.4

Now, if she draws 50 marbles more, she should expect to get:

0.4×50 = 8

Hence, Tanya should expect to pull a purple marble for 8 times.

After 8 seconds the ball height was 42 units.

It is given that on a game show, contestants shoot a foam ball toward a target. The table includes points along one path the ball can take to hit the target where x is the time that has passed since the ball was launched and y is the height at this time.

It is required to find how high was the ball after 8 seconds.

It is defined as the graph of a quadratic function that has something bowl-shaped.

The orbit of the ball will be a parabola.

We know the standard form of a quadratic function:

[tex]\rm y=ax^2+bx+c[/tex]      where [tex]\rm \\a\neq 0[/tex]

At x = 0 and y = 10, we get:

[tex]\rm 10 =a(0)^2+b(0)+c\\\rm 10= c\\\rm c=10[/tex]

At x = 2 and y=24, we get:

[tex]\rm 24= a(2)^2+b(2)+c\\\rm 24=4a+2b+10\\\rm 4a+2b=14[/tex]....(1)

At x = 16 and y = 10, we get:

[tex]\rm 10= a(16)^2+b(16)+c\\\rm 10=256a+16b+10\\\rm 256a+16b=0 \\[/tex]....(2)

By solving equations (1) and (2), we get;

a = - 1/2, b = 8 and c = 10

Putting these values in the standard form of a quadratic function, we get:

[tex]\rm y = - \frac{1}{2} x^2+8x+10\\[/tex]

Now, after 8 seconds means when x = 8, we get:

[tex]\rm y=-\frac{1}{2}\times 8^2 +8\times8+10\\\rm y = -32+64+10\\\rm y= 42[/tex]

Thus, after 8 seconds the ball height was 42 units.

[tex]\displaystyle [7x + 2][3x - 7][/tex]

Step-by-step explanation:

Find two quantities that when differed to 43, they also multiply to 294. Those will be 6 and 49. The TINIER quantity gets the plus symbol because the B-value is −43, therefore 49 gets the minus symbol, leaving 6 with the plus symbol. In extension, sinse we have a leading coefficient greater than one, we need to take extra procedures. Here is how it is done:

[tex]\displaystyle 21x^2 - 43x - 14 \\ \\ [21x^2 + 6x] - [49x - 14] \\ 3x[7x + 2] - 7[7x + 2] \\ \\ \boxed{[7x + 2][3x - 7]}[/tex]

complementary angles is when the sum of two angles is equal to 90 degrees.

∠A +  ∠B = 90°

21° + ∠B = 90°

∠B = 90° - 21°

∠B = 69°

Answer:

∠B = 69°

Step-by-step explanation:

Complementary angles are such pairs of angles that sum up to 90°. In this case, we are given that ∠A and ∠B are a pair of complementary angles. This means that ∠A and ∠B sum up to 90°.

⇒ [tex]\angle A + \angle B = 90\°[/tex]

⇒ [tex]21\° + \angle B = 90\°[/tex]                                                                                    [∠A = 21°]

⇒ [tex]\angle B = 90 - 21[/tex]

6/4 = 3/2 (divided the top and bottom by 2)

yes the ratio is the same

Answer:

To compare, first find out what the ratio of boys to students is at the beginning of the school year: 12/8 or, in the simplest form, 3/2.Once school resumes in January, that ratio becomes 18/12 - (12 + 6)/(8 + 4) - or 3/2 in simplest form.Therefore, the ratio is still the same.

Answer:

312,000,000

Step-by-step explanation:

Standard notation is when you move the decimal however many times the 10 is being squared by. In this case, it is 8.

Since the 8 is not negative, we move it 8 times to the right.

Since there are only 2 digits, we add 6 more zeros because 2+6=8

that is how you get 312,000,000

Answer:

3,500=3.5

500=0.5

75=0.075

1=0.001

x=x÷1000

7.5 × 10¹⁸
