Your answer would be 1. Hope this helps :)

0.96 rounded to the nearest tenth is:

1

Because 6 is greater than 4. The number has to be greater than 4 for it to be rounded up, but if it's not, then the number only gets rid of the number behind the tenth.

Step-by-step explanation:

Reggie's score changed by 350 points.

Reggie lost 4 spaceships in level 3 of a video game, and he lost 50 points for each spaceship. So, the total points lost would be 4 multiplied by 50, which is 200 points. However, when Reggie completed level 3, he earned a bonus of 550 points. To find out how much his score changed, we need to consider both the points lost and the bonus earned.

Points lost: 4 spaceships x 50 points/spaceship = 200 points

Bonus earned: 550 points

Score change: Bonus earned - Points lost = 550 points - 200 points = 350 points

Therefore, Reggie's score changed by 350 points.

The formula of a midpoint:

[tex]M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)[/tex]

We have:

[tex]A(8,\ 4)\to x_A=8,\ y_A=4\\B(12,\ 2)\to x_B=12,\ y_B=2[/tex]

Substitute:

[tex]\dfrac{8+12}{2}=\dfrac{20}{2}=10\\\\\dfrac{4+2}{2}=\dfrac{6}{2}=3[/tex]

Let's first recall what is known as the Midpoint formula we have, so by the Midpoint formula, we know that, the midpoint of any line segment joining the points [tex]{\bf{A(x_{1},y_{1})}}[/tex] and [tex]{\bf{B(x_{2},y_{2})}}[/tex] is given by

Now, if we assume our points to be A(8,4) and B(12,2) and the midpoint being M, then we will be having :

[tex]{:\implies \quad \sf M=\bigg(\dfrac{8+12}{2},\dfrac{4+2}{2}\bigg)}[/tex]

[tex]{:\implies \quad \sf M=\bigg(\dfrac{20}{2},\dfrac{6}{2}\bigg)}[/tex]

Answer:

Option D

Yes 0.4

Step-by-step explanation:

A sequence is said to be arithmetic if there is a pattern as

nth term is got by adding d to n-1th term.

d = common difference

The sequence will look like

a, a+d,a+2d, a+3d,......

where I term= a and each time d is added to get the next term.

Our given sequence is

-0.3, 0.1, 0.5, 0.9, …

Let us find difference between Ii and I term

=0.1-(-0.3) = 0.4

Similarly iii term - ii term

=0.5-0.1 =0.4

and iv term - iii term = 0.9-0.5 = 0.4

Hence confirmed that this is an arithmetic sequence with I term =-0.3 and common difference = 0.4

Does it say how many less leashes the store has compared to X collars? Cause if it doesn't you'll just have to estimate the answer between I would say 5 and 7.

Constant of proportionality is given by: y=kx oy [tex]k=\frac{y}{x}[/tex]

So lets suppose y = 50 and x = 5 so k will be [tex]\frac{50}{5}=10[/tex]

This 10 will remain constant. For every $50 Michael saves $5, for $100 he will save  $10 , for $150 he will save $15 and so on.

So this 'k' will be same for each value of x and y.

Hey there!

The correct answer would be~

The diver is now swimming at -7 meters.

Here's how:

If the diver is already swimming at negative 10, going deeper would add to that.

(-10) + (-3) = -13

So at this point, he is at -13 meters. However, it says he rises 6 meters.

So if he rises, we need to subtract.

13 - 6 = 7

Therefore he is now at -7 meters.

Answer:

The answer is [tex]6x^{3} +39x^{2}+54x[/tex]

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = [tex]x+2[/tex]

Width (w) = [tex]3x[/tex]

Height (h) = [tex]2x+9[/tex]

By substituting these values to the equation above,

Volume of the rectangular prism = [tex](x+2)*3x*(2x+9)[/tex]

                                                      =[tex](3x^{2} +6x)*(2x+9)[/tex]

                                                      =[tex]6x^{3} +27x^{2} +12x^{2} +54x[/tex]

Final answer:

To factor the expression 16a+40b by finding the GCF, you determine that the GCF is 8 and then express the original terms as 8(2a + 5b). By distributing the GCF back into the factored terms and obtaining the original expression, you confirm the factorization is correct.

Explanation:

To factor the expression 16a+40b by finding the Greatest Common Factor (GCF), you first list the factors of each coefficient:

Factors of 16 are 1, 2, 4, 8, 16.

Factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40.

The GCF for these two numbers is 8 because it is the highest number that divides both 16 and 40 evenly. Now, you factor out the GCF from both terms in the expression:

8(2a + 5b)

To verify if the GCF is factored out correctly, you can distribute 8 back into the terms within the parentheses. If the original expression is obtained, the GCF was factored out correctly:

8*2a = 16a

8*5b = 40b

Therefore, the factored expression is correct, and Justine has successfully found and factored out the GCF.

Hello!

To find the midpoint of the line segment, use the formula: [tex](\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})[/tex]. In simpler terms, we are finding the average of the two points.

We can assign [tex]x_{1}[/tex] and [tex]y_{1}[/tex] to the point (5, 8), and (-1, 6) to  [tex]x_{2}[/tex] and  [tex]y_{2}[/tex].

[tex](\frac{5+(-1)}{2}, \frac{8+6}{2}) = (\frac{4}{2}, \frac{14}{2}) = (2, 7)[/tex]

Therefore, the coordinates of the midpoint of the line segment is (2, 7).

Final answer:

The coordinates of the midpoint of the line segment with endpoints (5,8) and (-1,6) are (2,7).

Explanation:

To find the coordinates of the midpoint of a line segment, we can use the midpoint formula which states that the x-coordinate of the midpoint is the average of the x-coordinates of the two endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the two endpoints.

Using the formula, we can find the midpoint of the line segment with endpoints (5,8) and (-1,6).

x-coordinate: (5 + (-1)) / 2 = 4 / 2 = 2

y-coordinate: (8 + 6) / 2 = 14 / 2 = 7

Therefore, the coordinates of the midpoint of the line segment are (2,7).
