O is the midpoint of segment IU. If I is (-7, 2) and O is (5, -8), what are the coordinates of U?
The coordinates of U, the endpoint of the segment, can be found by using the midpoint formula. The x-coordinate of U is (-7 + 5) / 2 = -1, and the y-coordinate is (2 + (-8)) / 2 = -3. Thus, the coordinates of U are (-1, -3).
Explanation:The coordinates of the midpoint O are given as (5, -8). To find the coordinates of the endpoint U, we can use the midpoint formula. The x-coordinate of the midpoint can be found by taking the average of the x-coordinates of the endpoints, and the y-coordinate can be found by taking the average of the y-coordinates. So, the x-coordinate of U is (-7 + 5) / 2 = -1, and the y-coordinate is (2 + (-8)) / 2 = -3. Therefore, the coordinates of U are (-1, -3).

Answer: 16 Rows
Step-by-step explanation: 48*10= 480, meaning there is 480 people that will be attending. If each row has 30 chairs you divide 480/30 which equals 16. If you multiply 16 times 30 you will get 480 (to check your answer)
Answer:
16 rows
Step-by-step explanation:
There are 48 members in the choir .
Each member expects to have 10 people in the audience.
That’s
48 x 10 = 480 people
There will be 480 people in the audience.
If each row has 30 chairs in it

peter packed 32 pints of pickles in a minute.Find peters pickle packing rate in ounces per minute
Answer:
2 per minute
Step-by-step explanation:
Peter's pickle packing rate in ounces per minute is found by converting pints to ounces. By multiplying the 32 pints he packs in a minute by 16 ounces per pint, it is determined that Peter packs 512 ounces of pickles per minute.
Peter's pickle packing rate needs to be converted from pints to ounces to find how much he packs in ounces per minute. Since there are 16 ounces in a pint, we can find Peter's rate in ounces by multiplying the number of pints by 16.
Here are the calculation steps:
Identify the number of pints Peter packs in a minute, which is 32 pints.
Multiply the number of pints by the number of ounces in a pint. Since there are 16 ounces in a pint, the calculation is 32 pints * 16 ounces/pint.
Calculate the total to find Peter packs 512 ounces of pickles in a minute.
Therefore, Peter packs 512 ounces of pickles per minute.

In the given image, you can observe we have two right triangles.
Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.
If the triangles are similar, we can define the following proportion between sides.
[tex]\frac{4}{a} =\frac{3}{6}\\ 24=3a\\a=\frac{24}{3}\\ a=8[/tex]
Now we use the Pythagorean's Theorem to find each hypothenuse.
[tex]c^{2} =4^{2} +3^{2}\\ c=\sqrt{16+9}=\sqrt{25} \\ c=5[/tex]
[tex]b^{2} =8^{2} +6^{2}\\ b=\sqrt{64+36}=\sqrt{100}\\ b=10[/tex]
Therefore, the missing sides are

factor the gcf: 6x^4y^3*21x^y^2-9x^2y
Answer:
GCF is [tex]9x^2y[/tex]
Step-by-step explanation:
When the GCF or the greatest common factor of the expression is required to be found, then take the common terms, and write the expression in the factor form first.
Now, here we have to find the factor of the expression:
[tex]6x^4y^3\cdot 21x^2y^2-9x^2y\\[/tex]
which can be re-written as:
[tex]6x^4y^3\cdot 21x^2y^2-9x^2y\\=126x^6y^5-9x^2y[/tex]
Now, this is further written as:
[tex]126x^6y^5-9x^2y\\=14\cdot \:9x^2x^4yy^4-9x^2y\\[/tex]
Here taking the term [tex]9x^2y[/tex] common, we will get:
[tex]14\cdot \:9x^2x^4yy^4-9x^2y\\=9x^2y\left(14x^4y^4-1\right)\\[/tex]
So we have the expression:
[tex]6x^4y^3\cdot 21x^2y^2-9x^2y= 9x^2y\left(14x^4y^4-1\right)\\[/tex]
So the GCF or the greatest common factor is
[tex]9x^2y[/tex]

Congruent angles must satisfy which of the following conditions?
A. The sum of their measures is 90°
B. They have the same angle measure.
C. They share a vertex and a side.
Answer:
B
Step-by-step explanation:
Congruent angles are angles that have the same measure. This is the primary condition that they satisfy. The sum of their measures being 90° or sharing a vertex and a side don’t necessarily define congruent angles.
Explanation:In the field of Mathematics, particularly in geometry, congruent angles are those which satisfy the condition of having the same angle measure. This implies that their measures, when compared, are equal. The other options you mentioned, like the sum of their measures being 90° or sharing a vertex and a side, don’t necessarily apply to all congruent angles. For instance, for two angles to sum to 90°, they would be complementary, not necessarily congruent.

What is the value of din millimeters?
A)
27 mm
B)
12 mm
C)
9 mm
D)
13 mm
Answer: B) 12
Step-by-step explanation: In order to solve this you have to know the scale factor between the two triangles. In order to do that you just need to take a similar side between the two triangles and divide them. For example:
10 / 15 = .6666
This is RW divided by RT
Now that you have the scale factor, you just need to multiply it by 18 to get WV.
18 x .666666 = 12
The value of d in millimeters is 12 mm and this can be determined by using the similar triangle property.
Given :
Triangle RST is similar to triangle RVW.The length of the segment RW = 10 mmThe length of the segment WT = 5 mmThe length of the segment TS = 18 mmThe following steps can be used in order to determine the value of d in millimeters:
Step 1 - The similar triangle property can be used in order to determine the value of d in millimeters.
Step 2 - Apply the similar triangle property on the triangle RST and triangle RVW.
[tex]\rm \dfrac{RW}{WV}=\dfrac{RT}{TS}[/tex]
Step 3 - Substitute the values of the known terms in the above expression.
[tex]\rm \dfrac{10}{d}=\dfrac{15}{18}[/tex]
Step 4 - Simplify the above expression.
[tex]\rm d = \dfrac{10}{15}\times 18[/tex]

Which describes how triangle FGH could be transformed to triangle F prime G prime H prime in two steps? On a coordinate plane, triangle F G H has points (negative 2, 1), (negative 3, 3), (0, 1). Triangle F prime G prime H prime has points (negative 8, negative 4), (negative 12, negative 12), (0, negative 4). Which identifies the transformation that occurred after the dilation? a dilation by a scale factor of 3 and then a reflection across the x-axis a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin a dilation by a scale factor of 4 and then a reflection across the x-axis a dilation by a scale factor of 4 and then a 180 degrees rotation about the origin
Answer:
A dilation by a scale factor of 4 and then a reflection across the x-axisExplanation:
1. Vertices of triangle FGH:
F: (-2,1)G: (-3,3)H: (0,1)2. Vertices of triangle F'G'H':
F': (-8,-4)G': (-12,-12)H': (0, -4)3. Solution:
Look at the coordinates of the point H and H': to transform (0,1) to (0,-4) you can muliply each coordinate by 4 and then change the y-coordinate from 4 to -4. That is a dilation by a scale factor of 4 and a reflection across the x-axis. This is the proof:
Rule for a dilation by a scale factor of 4: (x,y) → 4(x,y)(0,1) → 4(0,1) = (0,4)
Rule for a reflection across the x-axis:{ (x,y) → (x, -y)(0,4) → (0,-4)
Verfiy the transformations of the other vertices with the same rule:
Dilation by a scale factor of 4: multiply each coordinate by 44(-2,1) → (-8,4)
4(-3,3) → (-12,12)
Relfection across the x-axis: keep the x-coordinate and negate the y-coordinate(-8,4) → (-8,-4) ⇒ F'
(-12,12) → (-12,-12) ⇒ G'
Therefore, the three points follow the rules for a dilation by a scale factor of 4 and then a reflection across the x-axis.
Answer:a dilation by a scale factor of 4 and then a reflection across the x-axis

A cookie company uses 1/6 of a foot of cookie dough to make a cookie. How many feet of cookie dough is needed to make 15 cookies?
Answer:
2 3/6 feet of cookie dough
Step-by-step explanation:
Final answer:
To make 15 cookies, 2.5 feet of cookie dough is needed.
Explanation:
To find how many feet of cookie dough is needed to make 15 cookies, we can set up a proportion using the given information. The ratio 1/6 represents the amount of cookie dough needed to make 1 cookie. We can set up the proportion:
1/6 = x/15
To solve for x, we can cross multiply:
15 * 1 = 6 * x
Simplifying the equation gives:
15 = 6x
To isolate x, we can divide both sides of the equation by 6:
x = 15/6 = 2.5 feet of cookie dough
Therefore, 2.5 feet of cookie dough is needed to make 15 cookies.

Perform the indicated operation and write the result in the form a + bi.
4i(-i + 3) - 3(6 - 2i)
Answer:
- 14 + 18i
Step-by-step explanation:
Note that i² = ([tex]\sqrt{-1}[/tex] )² = - 1
Given
4i(- i + 3) - 3(6 - 21) ← distribute both parenthesis
= - 4i² + 12i - 18 + 6i
= - 4(- 1) - 18 + 18i
= 4 - 18 + 18i
= - 14 + 18i
The indicated operation of 4i(-i + 3) - 3(6 - 2i) in the form a + bi is -14 + 18i.
To perform the indicated operation and write the result in the form a + bi, we have to distribute and combine like terms carefully.
Starting with 4i(-i + 3), we distribute 4i:
4i * (-i) = -4i^2 = 4 (since i^2 = -1)
4i * 3 = 12i
This gives us 4 + 12i.
Now addressing the second part, -3(6 - 2i), we also distribute:
-3 * 6 = -18
-3 * (-2i) = 6i
This results in -18 + 6i.
Combining both parts (4 + 12i and -18 + 6i):
(4 + 12i) + (-18 + 6i) = (4 - 18) + (12i + 6i)
= -14 + 18i

what is product of the complex numbers 3 - 4i and -6 + i, where i =
Option C:
The product of 3 - 4i and -6 + i is -14 + 27i.
Solution:
Given complex numbers are 3 - 4i and -6 + i.
To find the product of these numbers.
Product of 3 - 4i and -6 + i
[tex]=(3 - 4i)(-6 + i)[/tex]
Multiply each term of first number with each term of second number.
[tex]=3 (-6 + i)-4i(-6+i)[/tex]
[tex]=3 (-6) + 3i -4i (-6)-4i^2[/tex]
Since the value of i² = -1
[tex]=-18+ 3i +24i-4(-1)[/tex]
[tex]=-18+27i+4[/tex]
[tex]=-14+27i[/tex]
The product of 3 - 4i and -6 + i is -14 + 27i.
Option C is the correct answer.
Here we just want to find the product of two complex numbers, we will see that the solution is -14 + 27i
Remember that the complex number i has the property:
i^2 = -1
Now we want to perform the multiplication between 3 - 4i and -6 + i
Then we have:
(3 - 4i)*(-6 + i) = -18 + 3i + (4i)*6 - (4i)*i = -18 + 27i + 4 = -14 + 27i
So the correct option is C.
