Step-by-step explanation:
To write an English expression as an algebraic one, you must first understand what the English is telling you. Then the translation is straightforward.
Algebraic representationA plus sign (+) signifies addition. Multiplication is signified several different ways. The simplest is writing the factors next to each other.
Parsing the EnglishThe objects involved in the addition are 6 and a product:
6 + product
The product is said to consist of two factors: 7 and "a number". The instructions say to use "x" for "a number", so the product can be written ...

What is the smallest possible length of the hypotenuse for a non-degenerate
right triangle with integer side lengths given that it has at least 1 leg of length
84.
The smallest possible length of the hypotenuse is 118
How to determine the hypotenuse?The given parameters are:
Triangle type: non-degenerate right triangleLegs: Length = 84 (at least 1)The non-degenerate implies that the right triangle has a positive area.
Since at least one length is 84, then both lengths can also be 84.
The hypotenuse is then calculated using the following Pythagoras theorem.
h^2 = 84^2 + 84^2
Evaluate the sum
h^2 = 14112
Take the square root of both sides
h = 118.8
Round down
h = 118
Hence, the smallest possible length of the hypotenuse is 118

Answer:
18+[tex]6\sqrt{5}[/tex]
Step-by-step explanation:
Since the helicopter flies east for six miles and north for 12 miles, it flies 18 miles. Then on the way back, it flies an unknown amount of miles. the path the helicopter takes is in the form of a triangle, and the path back is the hypotenuse of the triangle. To find the hypotenuse, we can do [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse. We do
[tex]6^2+12^2=c^2\\36+144=c^2\\180=c^2\\\sqrt{180}=c\\ 6\sqrt{5}=c[/tex]Therefore, the total distance flown by the helicopter is 18+[tex]6\sqrt{5}[/tex].

A polygon A prime B prime D prime C prime is shown with vertex A prime on ordered pair 1, 2 , vertex B prime on ordered pair 1, 4, vertex D prime on ordered pair 2, 5 and vertex C prime on ordered pair 2, 1.
What set of transformations is performed on ABDC to form A′B′D′C′?
A: A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
B: A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin
C: A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
D: A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
(Sorry if its hard to understand)
Answer: A
Step-by-step explanation:
Let's first review how turning about the origin changes a point's coordinates:
After rotating and translating some points, one can see the following pattern:
180° Rotation: (x,y) -> (-x,-y)90° Clockwise Rotation: (x,y) -> (y, -x)90° Counter-clockwise Rotation: (x,y) -> (-y, x)Translation a units to the left: (x, y) -> (x-a, y)Using these patterns will make it much easier to find the correct series of transformations than graphing each one.
A: A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
Using the patterns found above, this set of transformations would make (x,y) move first to (-y, x), then (-y-1, x).
A(2,-2) -> A'(1,2)B(4,-2) -> B'(1,4)D(5,-3) -> D'(2,5)C(1,-3) -> C'(2,1)B: A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin
This would make (x,y) move first to (x-1,y), then to (-y, x-1)
A(2,-2) -> A'(2, 1)B(4,-2) -> B'(2,3)D(5,-3) -> D'(3,4)C(1,-3) -> C'(3,0)C: A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
This would make (x,y) move first to (y, -x), then (y-1, -x)
A(2,-2) -> A'(-3, -2)B(4,-2) -> B'(-3,-4)D(5,-3) -> D'(-4, -5)C(1,-3) -> C'(-4, -1)D: A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
This would make (x,y) move first to (x-1,y), then (y, -x+1)
A(2,-2) -> A'(-2, -1)B(4,-2) -> B'(-2, -3)D(5,-3) -> D'(-3, -4)C(1,-3) -> C'(-3, 0)Therefore, the answer is A, as only it correctly matches to polygon A'B'D'C'.

What is the
range of
allowance
amounts?
Answer:
$15
Step-by-step explanation:
Range is the difference of the highest and lowest data.
Based on the given $20 is the highest and $5 is the lowest.
$20 - $5 = $15
Answer:
15
Step-by-step explanation:
you can think of this table as a data set--and you could even write it out
5, 5, 5, 10, ......... 20, 20 {I did not write it out in full of course}
so, when thinking about the range, we can think of it as a range of our data set.
We find the range of a data set by finding the difference between the highest and lowest values
So, we know that our highest data value (amount) is 20, and the lowest is 5:
20 - 5 = 15
meaning that there is a range of $15 in this data set of allowance amounts

Answer:
The answer is 74.
Step-by-step explanation:
To find the area, you have to divide the shape into rectangles. To solve, I divided it like the image above. (Sorry if the lines are squiggly I'm trying to do this fast)
So first, now that we've divided it into smaller rectangles, we find the area of the smaller ones. Remember, the area of a rectangle is length * height.
Since the two smaller rectangles are the same, we just need to find one and multiply it by 2.
[tex]3 \times 5=15 \\15\times 2=30[/tex]
So the area of the two smaller ones is 30. Now we need to find the big rectangle and add it together. We know that the length is 11, but we don't know the height. The height of the small rectangles was 5, so the height is 4 since 9 - 5 = 4. So to finish up, we do this:
[tex]11\times4=44 \\ 44 + 30=74[/tex]
So our final answer is 74.

Answer:7m^5 - 3m^3 + 9
Step-by-step explanation: You’d have to remove the brackets, but remember that the second has to have everything multiplied by -1, because there’s a minus sign in front of the second bracket. Then you’d group like terms, then add or subtract. Here’s the step by step
6m^5 + 3 - m^3 - 4m + m^5 - 2m^3 + 4m + 6
2. 6m^5 + m^5 - 2m^3 - m^3 + 4m - 4m + 6 + 3
Subtract or add what’s needed, which would be figures with the same variable and coefficient.
3. 7m^5 - 3m^3 + 9
After this, there’s nothing you can add, since the remaining figures don’t have the same variable.

what is the chance to get 4 items with 10% chance of each occurring, while there 8 items in total with other 4 items having a 90% chance of each occurring
Step-by-step explanation:
Simple events in probability have a certain chance of happening. For example, a 10% chance of rain today. When two or more probabilities are possible, they are added together to get the total probability. A 10% chance of snow and a 15% chance of hail would mean a 10% + 15% = 25% chance of bad weather. This article will show you how to find the probability of a simple event happening.
An appliance repair person charges $60 for a service call and a labor charge of $30 per hour. What is the rate of change represented in this situation? (PLEASE INCLUDE HOW TO SOLVE IT TYSM)
Answer:
30$ (the labor charge per hour)
Step-by-step explanation:
The rate of change can be described as the slope, or how much the y-value is going to change as the x-value increases by 1. So the first step would be to understand what is x and what is y in this context. Well usually y is the dependent variable and x is the independent variable, so as x changes y changes as a result. In this case the y would represent the price the repair person charges and the x would represent the amount of hours, since as the amount of hours changes, the price changes. And since the person charges 30$ per hour, that means the rate of change is 30, since as the amount of hours increases by 1, the price or amount charged increases by 30$
Answer: $30
Step-by-step explanation:
The appliance repair person charges $30 per hour, meaning the rate of change is 30

Three rectangular-shaped holes have been drilled passing all the way through a solid 3 × 4 x 5 cuboid. The diagrams show the front, side and top views of the resulting block. What fraction of the original cuboid remains?
The volume of a cuboid implies the product of its length, width, and height. So that the fraction of the original cuboid that would remain is [tex]\frac{7}{15}[/tex].
A cuboid is a solid derived from a rectangle, thus it has rectangular faces. Its volume can be determined by;
volume of a cuboid = length x width x height
In the given question, the volume of the original cuboid can be determined as;
volume = 3 x 4 x 5
= 60 Cubic units
Since holes can not be drilled at the intersection of the holes, then the volume of the hole has to be determined.
To determine the volume of the hole drilled, we have:
(6 x 3) + (3 x 2) + (2 x 2) = 28 Cubic units
So that the fraction of the original cuboid that would remain = [tex]\frac{28 cubic units}{60 cubic units}[/tex]

Write an algebraic expression for each statement:
a. The value of a three digit number if the tens digit is c, the hundreds digit is three less than the tens and the ones digit is 0?
b. The tens digit of a number is b and the units digit is twice as big. What is the value of the number in terms of b if the digits are reversed?
I hope you can help me with these questions!!
For the given sentences, the algebraic expressions are:
a) N = 110*c - 300
b) N = 12*b
How to get the algebraic expressions?
For the first statement:
A 3-digit number, where the tens digit is c, can be written as:
N = 100*a + 10*c + b
Then the hundreds digit is a, and here we know that is 3 less than the tens digit, then:
a = c - 3
The ones digit is b, here we know that it is 0, then b = 0.
Replacing that in our number we get:
N = 100*(c - 3) + 10*c = 110*c - 300
N = 110*c - 300
That is the algebraic expression.
b) A two-digit number can be written as:
N = b*10 + a
Where b is the tens digit and a is the ones digit.
Here we know that the units digit is twice as bit as the tens digit, then:
a = 2b
Replacing that we get:
N = b*10 + a = b*10 + 2b = 12*b
N = 12*b
That is the algebraic expression.
