Express in scientific notation. 65
Final answer:
The number 65 can be expressed in scientific notation as 6.5 × 10¹, where the original decimal was moved one place to the left.
Explanation:
To express the number 65 in scientific notation, we need to write it as a product of a number between 1 and 10 and a power of 10. Since 65 is a relatively small number, we will have only one digit to the left of the decimal point. We write 65 as 6.5 × 10¹, because we have moved the decimal one place to the left to get the number 6.5, which is between 1 and 10. The exponent on the 10 is positive because the original number was greater than 1.
In sciences like chemistry, scientific notation is frequently used to express large or small quantities. This is also helpful when entering data into a calculator; it's important to know the correct procedure for your particular calculator model. In case of uncertainty, consulting an instructor is advised.
(9x-8)+(x+10)+(x+2)=180 find x
Answer:
x = 16
Step-by-step explanation:
Simplifying
(9x + -8) + (x + 10) + (x + 2) = 180
Reorder the terms:
(-8 + 9x) + (x + 10) + (x + 2) = 180
Remove parenthesis around (-8 + 9x)
-8 + 9x + (x + 10) + (x + 2) = 180
Reorder the terms:
-8 + 9x + (10 + x) + (x + 2) = 180
Remove parenthesis around (10 + x)
-8 + 9x + 10 + x + (x + 2) = 180
Reorder the terms:
-8 + 9x + 10 + x + (2 + x) = 180
Remove parenthesis around (2 + x)
-8 + 9x + 10 + x + 2 + x = 180
Reorder the terms:
-8 + 10 + 2 + 9x + x + x = 180
Combine like terms: -8 + 10 = 2
2 + 2 + 9x + x + x = 180
Combine like terms: 2 + 2 = 4
4 + 9x + x + x = 180
Combine like terms: 9x + x = 10x
4 + 10x + x = 180
Combine like terms: 10x + x = 11x
4 + 11x = 180
Solving
4 + 11x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 11x = 180 + -4
Combine like terms: 4 + -4 = 0
0 + 11x = 180 + -4
11x = 180 + -4
Combine like terms: 180 + -4 = 176
11x = 176
Divide each side by '11'.
x = 16
Simplifying
x = 16
Your answer would be x = 16.
To find the answer you need to collect like terms on the left hand side by adding the x-terms and the numbers, and then solving for x.
9x + x + x = 11x
-8 + 10 + 2 = 4
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16

A. Multiply the top equation by two
B. Multiply the top equation by six
C. Multiply the bottom equation by three
D. Multiply the bottom equation by two
Answer:
D
Step-by-step explanation:
In this problem, we are adding the two equations and we want to get rid of y. To do this, we want one positive y and one negative y with the same coefficient because when we add the equations they will cancel each other out. The coefficient of the first equation's y is 4, so we want the second to be -4. The coefficient of the second equation's y is -2, and if we want it to be -4 we multiply it by -4/-2= 2, which is D. Once you do that you will get 4y and -4y in the first and second equations respectively and then you can add them to eliminate y!

If two similar rectangles have corresponding sides with a ratio of 2:3, what is the
ratio of their areas?
Answer:
4:9 ratio
Step-by-step explanation:
We know that the sides cannot be the same because it is a rectangle, therefore there is a width and length.
For the width, which is the shortest side, we will keep the radius as it is, that is, for rectangle 1 it will be 2 and for rectangle 2 it will be 3.
For the length, which is the longest side, we multiply the radius by two, which means that rectangle 1 will be 4 (2 * 2) and for rectangle 2 it would be 6 (2 * 3)
If we calculate the area it would be:
rectangle 1:
2 * 4 = 8
rectangle 2:
3 * 6 = 18
Which means that the radius is 8/18 = 4/9

(x + 2)
(6x + 10)
(a) What is the value of x? Show your work.
(b) What is the measure of angle B? Show your work.
Answer:
Below in bold.
Step-by-step explanation:
(a) The angles in a triangle add up to 180 degrees, so:
x + x + 2 + 6x + 10 = 180
8x + 12 = 180
8x = 168
x = 168/8 = 21 degrees.
(b) Angle B = x + 2
= 21 + 2 = 23 degrees.
Here is the histogram of a data distribution,

Which best describes the shape of this distribution?
A. Unimodal symmetric
B. Unimodal skewed
C. Bimodal symmetric
D. Uniform
E. Bimodal skewed
Answer:
Unimodal Skewed
Step-by-step explanation:
The best describes the shape of this distribution is E. Bimodal skewed
What is Bimodal skewed?If a histogram has one hump, it is unimodal; if it has two humps, it is bimodal; and if it has many humps, it is multimodal.
If a histogram is not symmetric, this will refer to as skewed.
It is positively skewed if the upper tail is longer than the lower tail.
It can have multiple peaks or be bimodal (two peaks) (or many peaks).
But a single distribution with two peaks characterizes a bimodal distribution.
This will appear as two separate bell curve shapes contained within two normal distributions on a graph that is displayed side by side.
We are given graph has 2 humps, we can conclude that the given distribution is Bimodal skewed.
Therefore, the given distribution is (E) Bimodal skewed as the distribution has 2 humps.

y = -5
5x + 4y= -20
And SHOW YOUR WORK PLEASE!!!!
Step-by-step explanation:
If y = - 5
Then put value of y
5x + 4(-5) = - 20
5x - 20 = - 20
5x = - 20 + 20
5x = 0
x = 0
Answer:
x = 0
y = -5
Step-by-step explanation:
Since you already have the value of y, all you need to do is plug it into the equation, like so:
5x + 4y = -20
5x + 4(-5) = -20
5x - 20 = -20
Add 20 to both sides:
5x - 20 = -20
+ 20 + 20
___________
5x = 0
Finally, divide both sides by 5:
5x = 0
x = 0
So now you have, x = 0 and y = -5

The eighth grade class is planning a trip to Washington DC this spring. They need a minimum of 75 people to attend in order to reserve buses. If 1/3 of the eighth grade class 17 parent chaperones have signed up and this is enough to satisfy the requirement, how many students must be in the eighth grade class?
By setting up an equation and solving for the number of students in the eighth grade class, we find that there must be 174 students to meet the requirement of 75 people including 17 parent chaperones.
To find the number of students in the eighth grade class for the trip to Washington DC, let's use the information provided that 1/3 of the class plus 17 parent chaperones are just enough to satisfy the requirement of 75 people for the trip. We can set up an equation to solve for the total number of students (S) in the class:
1/3 * S + 17 = 75
First, subtract 17 from both sides of the equation:
1/3 * S = 75 - 17
1/3 * S = 58
Then, multiply both sides by 3 to find the total number of students (S):
S = 58 * 3
S = 174
Thus, there must be 174 students in the eighth grade class.
In boot camp, a cadet must use a rope swing to cross an obstacle without falling into the water hazard below. Unfortunately, they miss the platform on the other side and swing back to where they started. If it takes the cadet 3.5 seconds to swing from one side of the obstacle to the other and back, how Lind is the rope swing? Use the formula: T= 2 pi square root over L/9.8
Answer:
3.04m
Step-by-step explanation:
Time taken to swing the rope = 3.5s
Length of the rope = L
T = 2π√(L / 9.8)
3.5 = 2π√(L / 9.8)
take the square of both sides
(3.5)² =[2π√(L/9.8)]²
12.25 = 39.48 × (L / 9.8)
12.25 = 39.48L / 9.8
39.48L = 12.25 × 9.8
39.48L = 120.05
L = 120.05 / 39.48
L = 3.04m
The length of the rope is 3.04m

What is a rectangle?A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length.
The perimeter of a rectangle is defined as the total distance covered by the outer boundary of the rectangle. It is measured in unit length. The formula of perimeter is given by:
Perimeter, P = 2 (Length + Width)
The area of the rectangle is the area covered by its outer boundaries. It is equal to the product of length and width.
The formula of area of rectangle is:
Area = Length × Width unit²
Given,
Length of the plywood (L) = 6 feet
Perimeter of Plywood (P)= 22 feet
Area of Plywood = ?
Perimeter = 2(Length + Width)
22 feet = 2 (6feet + Width)
Width (W) = (22 /2 - 6) feet
Width (W) = (11 - 6) feet
Width (W) = 5 feet
Area of the plywood (A) = Length × Width
Area = 6feet × 5feet
Area = 30 feet²
Hence, Area of the plywood (A) = 30 feet²

Answer:
-12.
Step-by-step explanation:
f(x)=-2x^2+5x-9
which is -18+15-9, which is...
MARK AS BRAINLIEST!!!!!!!!!!!!
To evaluate f(3) for the function f(x)=-2x^2+5x-9, you substitute 3 for x in the equation and simplify the expression to get the result, which is -12.
Replace x with 3: f(3)=-2(3)2+5(3)-9.
Simplify the squares: f(3)=-2(9)+5(3)-9.
Multiply through: f(3)=-18+15-9.
Combine the terms: f(3)=-3-9.
Final result: f(3)=-12.
Therefore, the evaluated result for f(3) is -12.

Step-by-step explanation:
The coordinates of the triangle showing a dilation with a scale factor of 1/3 is (-2, 2), (2, 2) and (2, -2)
What is dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
Given that, on a coordinate plane, triangle A B C has points (-6, 6), (6, 6), (6, -6). It is being dilated with a scale factor of 1/3
Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
Here, we will consider the coordinates in place of dimensions,
Therefore,
Scale factor = coordinates of new figure / coordinates of original figure
Considering the first option = A'(-2, 2), B'(2, 2) and C'(2, -2)
Scale factor = A/A' = 2/6 = 1/3
Hence, the coordinates of the triangle showing a dilation with a scale factor of 1/3 is (-2, 2), (2, 2) and (2, -2)

What is mArc B C? 50° 80° 100° 130°
Answer:
130
Step-by-step explanation:
The measurement of arc BC is 130°.
Step-by-step explanation:
Given : circle with origin O, with two line segments AC and BD which are also diameters.
Measurement of arc AB = (3 x -70)° =
Measurement of arc DC= (x +10)° = ∠3
To find : Measurement of arc BC = ∠2 =?
Solution:
Let angle subtended by the arc AC = ∠1 = (3 x -70)°
Let angle subtended by the arc BD = ∠2
Let angle subtended by the arc DC = ∠3 = ( x + 10)°
Let angle subtended by the arc AD = ∠4
AC and BD are intersecting each other at O.
So, ∠1 = ∠3 (vertically opposite angles)..[1]
∠2 = ∠4 (vertically opposite angles)..[2]
(3 x -70)° = (x +10)° (from [1])
3x - x = 10 + 70
∠1 = ∠3 = (x +10)° = (40 +10)° = 50°
∠1 + ∠2 + ∠3 + ∠4 = 360°
50° + ∠2 + 50° + ∠2= 360° (from [2])
2∠2 = 360° -50° - 50°
2∠2 = 260°
∠2 = 260° ÷ 2
∠2 = 130°
The measurement of arc BC is 130°.

Let angle subtended by the arc BD = ∠2
Let angle subtended by the arc DC = ∠3 = ( x + 10)°
Let angle subtended by the arc AD = ∠4
AC and BD are intersecting each other at O.
So, ∠1 = ∠3 (vertically opposite angles)..[1]
∠2 = ∠4 (vertically opposite angles)..[2]
(3 x -70)° = (x +10)° (from [1])

What is the circumference?
The circumference of the circle is 360 degrees the circle.
∠1 = ∠3 = (x +10)° = (40 +10)° = 50°
∠1 + ∠2 + ∠3 + ∠4 = 360°
50° + ∠2 + 50° + ∠2= 360° (from [2])
2∠2 = 360° -50° - 50°
