Answer: The total weight is [tex](1.14)(10^{7})[/tex] pounds.
Step-by-step explanation:
1. To solve this problem you need to multiply the number of whales by the weight. Based on the given information, the weight of each whale is approximately [tex](3.8)(10^{5})[/tex] pounds, therefore:
[tex](30)[(3.8)(10^{5})]=11,400,000[/tex] pounds.
3. To express the result in scientific notation, you must move the decimal point to the right until you have a non-zero number on the left of the decimal point. Then, it is:
[tex](1.14)(10^{7})[/tex]
Answer: The group weights 1.14x10^7 pounds
Step-by-step explanation:
The group has 30 whales.
Each whale weights 3.8x10^5 pounds, then, 30 whales weight 30 times that amount:
Total weight = (30)*(3.8x10^5)
Remember that for the scientific notation we want only one digit before the decimal point.
Here, i will use that 30 = 3x10^1
(3x10^1)*(3.8x10^5) pounds = (3*3.8)x10^(5 + 1) pounds
(11.4)x10^6 pounds
and 11.4 = 1.14x10^1
(11.4)x10^6 pounds = 1.14x10^(1 + 6) pounds = 1.14x10^7 pounds

Answer:
Tony pays $6.75 for his item, & Tanya pays $9 for her items
Step-by-step explanation:
Let Tanya's item be x, and Tony's be y. Set the system of equality:
3x = 4y
y = x - 2.25
Plug in x - 2.25 for y in the first equation
3x = 4(x - 2.25)
Distribute 4 to all terms within the parenthesis
3x = 4x - 9
Isolate the x. Subtract 4x from both sides
3x (-4x) = 4x (-4x) - 9
3x - 4x = -9
-x = -9
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-9)/-1
x = 9
-------------------------------------------------------------------------------------------------------------------
Plug in 9 for x in the equation
y = x - 2.25
y = (9) - 2.25
y = 6.75
--------------------------------------------------------------------------------------------------------------------
Tony pays $6.75 for his item, & Tanya pays $9 for her items

Ella owns 15% of Fitz Incorporated. The rest of the shares are owned equally by the remaining 5 shareholders. What percent of the corporation does each of the other shareholders own?
Answer:
17%
Step-by-step explanation:
The total corporation shares is 100%If Ella owns 15% of Fitz,the remaining shares is 100-15=85%If there are 5 shareholders and they all own equal shares,the percentage for each shareholder will be;85/5=17% eachFinal answer:
Ella owns 15% of Fitz Incorporated, and the remaining 85% is shared equally among 5 other shareholders. Thus, each of these shareholders owns an equal share of 17% of the corporation.
Explanation:
The question asks about corporate stock and how it relates to the percentage of ownership in a corporation. Ella owns 15% of Fitz Incorporated, and the remaining 85% is owned equally by 5 other shareholders. To find the percentage each of these shareholders owns, we divide the remaining percentage by the number of shareholders.
The calculation would be:
Subtract the percentage owned by Ella from the total, which is 100% - 15% = 85%.
Divide this remaining percentage (85%) by the number of other shareholders, which is 5.
85% / 5 = 17% ownership for each of the other shareholders.
So, each of the remaining 5 shareholders owns 17% of the corporation.

Answer: Yes it is possible. Angle DCF is also 50 degrees
=================================================
Check out the image attachment below. On that image, I've marked that angle EBA is congruent to angle BAC by the alternate interior angle theorem. Those angles are shown in red. Furthermore, angle BAC is congruent to DCF (corresponding angles) using a green marker. Finally, using the transitive theorem, you can connect the statements in a chain to say that angle EBA is congruent to angle DCF, which is why angle DCF is 50 degrees as well.

Reggie Lost 4 spaceships in level 3 of a video game he lost 50 points for each spaceship when he completed level 3 he earned a bonus of 550 points by how much to his score change?
Reggie's score changed by 350 points.
Explanation: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.

calculate midpoint of (8,4) and (12,2)
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]
Answer: (10, 3).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
[tex]{\boxed{\bf{M(x,y)=\bigg(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2}\bigg)}}}[/tex]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 :

The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is the height. Which expression represents the volume of the following rectangular prism?
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]
=[tex]6x^{3} +39x^{2}+54x[/tex]
Therefore,
The answer is [tex]6x^{3} +39x^{2}+54x[/tex]
Answer:
Volume = [tex]6x^3+39x^2+54x[/tex]
Step-by-step explanation:
Prism is an object which has two bases which are parallel to each other and other faces are parallelograms .
Rectangular prism is a three dimensional figure which has 6 faces which are all rectangles .
Let l be the length of rectangular prism , w be the width of prism and h be the height of prism .
Then volume of rectangular prism is equal to [tex]lwh[/tex] .
We will also use formula: [tex]a(b+c)=ab+ac[/tex]
Here,
[tex]l=x+2\\w=3x\\h=2x+9[/tex]
Therefore,
volume of rectangular prism is calculated as follows:
[tex]V=\left ( x+2 \right )\left ( 3x \right )\left ( 2x+9 \right )\\=\left ( 3x^2+6x \right )\left ( 2x+9 \right )\\=3x^2\left ( 2x+9 \right )+6x\left ( 2x+9 \right )\\=6x^3+27x^2+12x^2+54x\\=6x^3+39x^2+54x[/tex]
For every $50.00, Michael earns, he saves $5.. for the future. what is the constant of proportionality (k)?
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.
Is the following sequence arithmetic? If so, identify the common difference.
-0.3, 0.1, 0.5, 0.9, …
A) Yes; -0.2
B) No
C) Yes; -0.4
D) Yes; 0.4
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
