Triangle UVW is drawn with vertices at U(−1, 1), V(0, −4), W(−4, −1). Determine the coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° counterclockwise.
U′(1, −1), V′(0, 4), W′(4, 1)
U′(−1, −1), V′(4, 0), W′(1, −4)
U′(−1, 1), V′(4, 0), W′(1, 4)
U′(−1, 1), V′(0, −4), W′(−4, −1)
Answers
The correct answer is U′(1, −1), V′(4, 0), W′(1, 4). When a point is rotated 90° counterclockwise about the origin, the x-coordinate and y-coordinate change places, and the sign of the new x-coordinate is the opposite of the original y-coordinate. So for example, point U(−1, 1) becomes U′(1, −1).

Step-by-step explanation:
In order to find the number of solutions, we have to expand both sides out first.
\(3(x - 2) + 7x = \frac{1}{2} (6x - 2)\)
First, expand 3(x-2), which will obtain 3x-6.
Next, expand (1/2)(6x-2), which gives 3x - 1.
The result at this point should be as shown below:
\(3x - 6 + 7x = 3x - 1\)
Now, we would shift all x terms to the left and all number terms to the right.
\(3x + 7x - 3x = - 1 + 6\)
After simplifying, the final equation would be:
\(7x = 5\)
This is a linear equation and it has one solution.

The area of the rectangular figures obtained by the multiplication of the dimensions expressed as fractions are presented as follows;
The number of (1/2)-yards lengths in 1 yard = 2The number of (1/3)-yard lengths in 1 yard = 3The area of 1 square yard is equivalent to 3 columns or 6 rectangles(4/6) square yard covers less area than 1 square yardWhat is a fraction?A fraction is a representation of proportion or part of a whole, presented as a value with a numerator value part located above a denominator.
1) The number of (1/2) of a yard, n, that are in 1 yard can be found by dividing 1 yard by (1/2) yard by dividing by a fraction as follows;
n = (1 yard)/((1/2) yard) = 1/(1/2) = 1 × 2/1 = 2
The number of (1/2) yards in 1 yard = 22) The number of (1/3) yard lengths, n, that are in 1 yard can be found similarly as follows;
n = (1 yard)/((1/3) yard) = 1/(1/3) = 1 × 3/1 = 3
The number of (1/3) yard lengths in 1 yard = 33. The dimensions of each unit rectangle in the model are;
Height = (1/2) yard
Width = (1/3) yard
A 1 square yard area, A is therefore;
A = (2 height lengths) × (3 width lengths)
A = (2 × (1/2) yard) × (3 × (1/3) yard) = (1 yard) × (1 yard) = 1 square yard
The area of 1 square yard is therefore the first three columns of the model, which is six rectangles.4. (4/6) square yard is the product of the (1/2) yard and (4/3) yard, which is represented by the top row or four rectangles, therefore;
(4/6) square yard which is 4 rectangles covers less area than 1 square yard which covers 6 rectangles.

At the store you want to buy a bunch of 3d printed Christmas gifts for your family. Each large tree costs $4.50 , and each small tree costs $2.25, If you buy 4 large trees, and can spend a total of $50. Write and solve an inequality for number of small trees (s) you can buy
Answers
We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.
If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.
The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.
To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:
s * $2.25 = $32
s = $32 / $2.25
s = 14.22
Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.
Answer:
If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Answer: y=x-20
Step-by-step explanation:
(90,70) will be x1,y2. (30,10) will be x1,y1. Put these values into the slope formula, which is y2-y1/x2-x1. 70-10/90-30. 60/60=1. The slope is 1. Now to find the slope-intercept equation, use point slope form which is y-y1=m(x-x1). y-10=1(x-30). Distribute the 1 to the terms in the parenthesis. y-10=x-30. Add 10 to both sides to eliminate 10. y-10+10=x-30+10. y=x-20.

Answer:
A = 30cm²
Step-by-step explanation:
First, let's find the area of the triangle
Formula: 1/2 bh
The base is half of 5, which is 2.5
A = 1/2 (2.5)(4)
A = 5cm²
Next, let's find the area of the rectangle
Formula: bh
Base = 5cm
Height = 5cm
A = bh
A = (5)(5)
A = 25cm²
Now you add those two.
25 + 5 = 30cm²
A = 30cm²

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

can someone explain how to find the surface area to this composite figure.
Answers
Answer:
Surface Area= 498 cm²
Step-by-step explanation:
To calculate the surface area of this composite shape, work out the area of each face and add them together (break this composite figure into two shapes)
- Calculate the areas of the different sized faces
7 x 7 = 49
12 x 7 = 84
12 x 7 = 84
- Now, multiply these areas be number of corresponding faces
49 x 2 = 98
84 x 2 = 168
84 x 2 = 168
- Add these areas together
98 + 168 + 168 = 434
Now do the same for the shape above it
2 x 2 = 4 → 4 x 2 = 8
2 x 7 = 14 → 14 x 2 = 28
7 x 2 = 14 → 14 x 2 = 28 = 64
Add the surface areas together : 434 + 64 = 498 cm²
