Answer:
25% of $8.00 is $2.00
Step-by-step explanation:
25% is basically 1/4 of something. So, if you divide $8.00 into four parts, you would get $2.00 for each part. This is why 25% of $8.00 is $2.00.
Answer:
$2
Step-by-step explanation:
Think you have 25/100 x of 8
100/25 is the same as 8/x:
X=8/100 divided by 25=$2

Answer:
Conner's work is correct
Step-by-step explanation:
Operations With Exponents
We need to use the rule to find the product of two or more exponential expressions:
[tex]x^m\cdot x^n\cdot x^p = x^{m+n+p}[/tex]
We need to multiply:
[tex](3^5 6^8)(3^9 6^{10})[/tex]
Base 3 is treated independently from base 6, so we have two groups of operations:
[tex](3^5 6^8)(3^9 6^{10})=3^{5+9} 6^{8+10}[/tex]
Adding the exponents:
[tex](3^5 6^8)(3^9 6^{10})=3^{14} 6^{18}[/tex]
Thus, Conner's work is correct
PLS HELP DO NOT JUST PUT A RANDOM ANSWER PLEASE 15 POINTS!!!
Answer:
Step-by-step explanation:
Where's the question?
But if the question is to represent the equation on the graph then
Just fix in any random value for x,say x=3...then insert into into your equation y=3/2x-1 y=3/2(3)-1 y will be 3.5 when x is 3 so you get a coordinate like(3,3.5) repeat that for about three more values then plot a line

Pentagon QRSTU is dilated to form pentagon Q'R'S'T'U' .
If Q is located at (-2, 1) , which of the following can be used to determine the location of R?
Please look at the picture below.... the answer choices are also there.
Answer:
C
Step-by-step explanation:
Here, originally, we are told that the point Q has coordinates (-2,1)
Now, its dilated point has the coordinates (-8,4)
what we can observe here is the the shape original polygon was dilated by a factor of 4 to give the image
Now the point R’ is (0,8)
To get the point R , we simply divide each coordinate by 4
Thus, we have (0/4 , 8/4)
This is same as option C

5. Purple Bricks are stacked according to the pattern below. Each row contains 2 more bricks than the row above it!
Part A.
Determine a Quadratic Function to model the total number of bricks in the stack, f(x), given a number of rows X.
Part B.
If there are 50 rows in the stack, how many bricks would there be ? Use your quadratic function to determine the number of rows. Show your work and explain your reasoning
Answer:
Part A
The Quadratic Function to model the total number of bricks the stack is f(x) = x²
Part B
The number of bricks we will have for 50 rows is 2500 bricks
Step-by-step explanation:
Part A
Let the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = a·x² + b·x + c
We have;
When x = 0, f(x) = 0, therefore, f(0) = a×0² + b×0 + c = 0 + 0 + c = 0
∴ c = 0
When x = 1, f(x) = 1, therefore, f(1) = a×1² + b×1 + 0 = 1
∴ a + b = 1...(1)
When x = 2, f(x) = 4, therefore, f(2) = a×2² + b×2 = 4
∴ 4·a + 2·b = 4...(2)
Multiply equation (1) by 2, and subtract it from equation (2) gives;
4·a + 2·b - 2×(a + b) = 4 - 2 × 1
2·a = 2
a = 1
From equation (1), we have;
b = 1 - a = 1 - 1 = 0
b = 0
∴ f(x) = a·x² + b·x + c = 1·x² + 0·x + 0 = x²
Therefore, the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = x²
Part B
If there are 50 rows in the stack, then we have, x = 50
Therefore;
f(50) = 50² = 2500
The number of bricks we will have for 50 rows is f(50) = 2500 bricks

Answer:
An expression obtained from the square of binomial equation is a perfect square trinomial. An expression is said to a perfect square trinomial if it takes the form ax2 + bx + c and satisfies the condition b2 = 4ac. The perfect square formula takes the following forms: (ax)2 + 2abx + b2 = (ax + b)
A math quiz has 10 questions and is scored out of 100. Each question is worth the same. The function S(q) represents the quiz score, S, in terms of the number of correctly answered questions, q.
Determine whether each statement below is true or false. Select True or False for each statement
Statements are;
1) S(q) represents a quantity that changes at a constant rate per unit interval.
2) S(q) represents a quantity that changes at a constant percent rate per unit interval
3) S(q) represents a linear function
4) S(q) represents an exponential function.
Answer:
Statements 1 & 3 are true while statements 2 & 4 are false
Step-by-step explanation:
We are told that S(q) is a function that represents the quiz score, S, in terms of the number of correctly answered questions, q.
Statement 1 is true because the quiz score(S(q)) changes at a constant rate per unit questions answered since the math quiz has 10 questions and is scored out of 100
Statement 2 is false because S(q) is not expressed as a percentage rate.
Statement 3 is correct because S(q) function is a straight linear functional relationship where it directly depends on the number of correctly answered questions(q)
Statement 4 is false because the relationship is not expressed in exponential form but as a direct linear relationship.
The function S(q) is an illustration of a linear function.
The true statements are:
a) S(q) represents a quantity that changes at a constant rate per unit interval. c) S(q) represents a linear functionThe false statements are:
b) S(q) represents a quantity that changes at a constant percent rate per unit interval d) S(q) represents an exponential function.
From the question, we understand that:
S(q) represents the quiz score in terms of the number of correct answers
This means that:
As the correct answers increases or decreases, the value of s(q) changes at a constant interval
Functions that have such behavior are linear functions because they change at a constant rate
Hence, (a) and (c) are true, while (b) and (d) are false.

Answer:
no solutions
Step-by-step explanation:
3x+ 7(x+1) = 2(6x+5) -2x
Distribute
3x+7x+7 = 12x+10-2x
Combine like terms
10x+7 = 10x+10
Subtract 10 from each side
10x+7-10x = 10x+10-10x
7 = 10

If W(-10, 4), X(-3, -1), and Y(-5, 11) classify ΔWXY by its sides. Show all work to justify your answer.
Given:
The vertices of ΔWXY are W(-10, 4), X(-3, -1), and Y(-5, 11).
To find:
Which type of triangle is ΔWXY by its sides.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, we get
[tex]WX=\sqrt{(-3-(-10))^2+(-1-4)^2}[/tex]
[tex]WX=\sqrt{(-3+10)^2+(-5)^2}[/tex]
[tex]WX=\sqrt{(7)^2+(-5)^2}[/tex]
[tex]WX=\sqrt49+25}[/tex]
[tex]WX=\sqrt{74}[/tex]
Similarly,
[tex]XY=\sqrt{\left(-5-\left(-3\right)\right)^2+\left(11-\left(-1\right)\right)^2}=2\sqrt{37}[/tex]
[tex]WY=\sqrt{\left(-5-\left(-10\right)\right)^2+\left(11-4\right)^2}=\sqrt{74}[/tex]
Now,
[tex]WX=WY[/tex]
So, triangle is an isosceles triangles.
and,
[tex]WX^2+WY^2=(\sqrt{74})^2+(\sqrt{74})^2[/tex]
[tex]WX^2+WY^2=74+74[/tex]
[tex]WX^2+WY^2=148[/tex]
[tex]WX^2+WY^2=(2\sqrt{37})^2[/tex]
[tex]WX^2+WY^2=WY^2[/tex]
So, triangle is right angled triangle.
Therefore, the ΔWXY is an isosceles right angle triangle.
Given the diagram below, find X. The diagram IS
40°
x - 15°
X =
degrees.
Answer:
X=65°
Step-by-step explanation:
Both angles combined is a right angle as indicated by the small square drawn on it, a right angle is always 90° therefore
(x-15°)+40°=90°
combine like terms
x+25°=90°
subtract 25° from each side
x=65°

find the volume of the cone with radius 35dm and slant height 37dm
Answer:
Volume of cone is: 47464.23 dm³
Step-by-step explanation:
We are given:
Radius of cone r = 35 dm
Slant Height of cone h = 37 dm
We need to find Volume of the cone.
The formula used to find Volume is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]
Putting values and finding volume:
[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14*(35)^2 *\frac{37}{3}\\Volume=47464.23\ dm^3[/tex]
So, volume of cone is: 47464.23 dm³
