Step-by-step explanation:
Triangle XYZ is translated by the rule (x + 1, y − 1) and then dilated by a scale factor of 4 centered at the origin. Which statement describes the properties of triangles XYZ and X''Y''Z'' after the transformations?
A. Y and ∠Y'' are congruent after the translation, but not after the dilation.
B. ∠Y and ∠Y'' are congruent after the dilation, but not after the translation.
C. segment YZ and segment Y double prime Z double prime are proportional after the translation, but not after the dilation.
D. segment YZ and segment Y double prime Z double prime are proportional after the dilation and congruent after the translation.
The statement that described the triangle properties is that the segment YZ and segment Y"Z" should be proportional when the dilation is done and it should be congruent when the translation should be done.
Given that,
There is the rule i.e. (x +1, y - 1) and it should be dilated by a scale factor of 4 centered at the origin.Based on the above information,
The figure should be proportional as the angle and the points should be the same. And, when the translation is done the image should be congruent to the pre-imageTherefore we can conclude that option d is correct.

Hey ! Buddy
Question : -Find the value of x .
Given : -Angle 1 = x°Angle 2 = 43°Angle 3 = 36°To Find : -We have to find the value of x .
Concept : -The concept of this question belongs to the sum of all the three interior angles of triangle i.e. sum of all the three interior angles of triangle is equal to 180° .
So Our Solution Starts From Here :As we know that sum of all the three interior angles of triangle is equal to 180° . So ,
[tex] \rightarrow \: Angle \: 1 + Angle \: 2 \: + Angle \: 3= 180°[/tex]
Now , substituting values of Angle 1 , 2 and 3 :
[tex] \longmapsto \: x° + 43° + 36° = 180° [/tex]
Now , adding 43 and 36 in right hand side :
[tex] \longmapsto \: x° + 79° = 180° [/tex]
Now , transposing 79° to right hand side :
[tex] \longmapsto \: x° = 180° - 79° [/tex]
Now , subtracting 79° from 180° :
[tex] \longmapsto \: \pink{\boxed{ { \bold{x° = 101°}}}}[/tex]
Therefore , value of angle x is 101°.#[tex] \sf{Keep \: Learning}[/tex]a _______has one endpoint line or ray

what is 20 - 10
what is 20+ 10
Answer:
20-10=20
20+10=30
Step-by-step explanation:
For 20-10 let's assume John has 20 apples. He gives 10 to Carol.
Understand that subtraction can mean taking away or finding a difference. For example, 13 – 8 can mean, “How many are left when you take 8 away from 13?” Or, 13 – 8 can be interpreted as, “How much more is 13 than 8?” Understand that subtraction is the opposite of addition. Know the addition facts up to 9 + 9.
If john has 20 apples and gives 10 to carol, he will have 10 left.
For 20+10, we do the opposite operation, which is addition.
Addition is finding the total value of two or more numbers. Addition is shown using the + symbol in maths sums.
If john has 20 apples and buys 10 more, he will have 30 apples.

What is the profit?
Profit = revenue - total cost
Revenue = 443 x 28.99 = $12,842.57
Total cost = $3692 + (9.15 x 443) = $7,745.45
Profit = $12,842.57 - $7,745.45 = $5097.12
What is the price?
Price = (profit + total cost) / number of customers
Total cost = $2,345 + (16.90 x 45) = $3,105.50
($6,135.00 - 3105.50) / 45 = $205.34

Write an equation using x when the sum of a number and 8 is multiplied by 3and the answer is 6
Answer:
3(x + 8) = 6
Step-by-step explanation:
let the number be x then the sum of x and 8 is x + 8 and multiplied by 3 is
3(x + 8) = 6 ( divide both sides by 3 )
x + 8 = 2 ( subtract 8 from both sides )
x = - 6

Let a represent a positive number and let b represent a negative number. Tell whether each statement is True or False. True False a. The difference (a - b) could be negative. True False b. The difference (b − a) cannot be positive. True False C. The sum (a + b) could be positive. True False d. The sum (b + a) must be negative.
a. False; if b is negative, then -b is positive, so
a - b = a + (-b)
is the sum of two positive numbers, which must be positive.
b. True; the sum of two negative numbers is again negative.
c. True; a + b will be positive as long as a > |b|. (For example, if a = 2 and b = -1, then of course 2 > |-1| = 1, and a + b = 2 + (-1) = 1 > 0.)
d. False; this would contradict the result of part (c). b + a is only negative if a ≤ |b|. (For example, if a = 1 and b = -2, then b + a = -2 + 1 = -1 < 0.)

Find the volume of the sphere. Round your answer to the nearest tenth.
Use 3.14 for a.
A sphere has a radius of 3.5 feet.
The volume of the sphere is about
ft?
Answer:
179.50
Step-by-step explanation:
The formula for calculating pi is as followed: 4/3·π·r³
The question is either asking to calculate using 3.14 for π or add π at the end of your answer instead of completing it. I will substitute π for 3.14.
∴V=4/3·3.14·3.5³
V=179.503333333
Round your answer to the nearest hundredth:
179.503333333 rounded to the nearest hundredth becomes 179.50
∴V=179.50
-------------------------------------------------------------------------------------------------------------
Another way to answer this question is to use the same formula; but not substitute 3.14 into the answer.
V=π.4/3·r³
V=π·57.1666666667
Round 57.1666666667: 57.17
V=57.17π
Either one would work. Hope this works.

he roof of a castle tower is shaped like a cone. The base of the cone is 24 m across and the height is 16 m. The slant height of the roof, which is unknown, is the hypotenuse of the right triangle formed with the radius and the height of the cone.
What is the slant height of the roof?
==========================================================
Explanation:
The base of the cone is 24 m across. This is the diameter of the circle. Divide it in half to get 24/2 = 12 m as the radius.
We can form a right triangle inside the cone such that the horizontal piece is the radius 12 m and the vertical piece is the height 16 m. The hypotenuse of this right triangle is the slant height. This is all mentioned in the instructions of course.
We'll use the pythagorean theorem to find the hypotenuse.
[tex]a^2 + b^2 = c^2\\\\c = \sqrt{ a^2 + b^2 }\\\\c = \sqrt{ 12^2 + 16^2 }\\\\c = \sqrt{ 144 + 256 }\\\\c = \sqrt{ 400 }\\\\c = 20 \text{ meters is the slant height}\\\\[/tex]
It is the distance from the circular base to the peak of the cone, when traveling along the outside of the cone. This is a straight line distance.

Step-by-step explanation:
find the missing length of the triangle using Pythagoras then use this value (8) to find the surface area of the sides and the triangle.Add up the values.
Answer:
Step-by-step explanation:
To find the lateral surface area of triangular prism, first we need to know the three sides of the triangle. Here, one side is missing and we have to find that using Pythagorean theorem. Let the unknow side of the triangle be 'c'
Pythagorean theorem,
15² + c² = 17²
225 + c² = 289
c² = 289 - 225
c² = 64 = 8*8
c = 8 in
a = 17 in & b = 15 in & h = 18 in
[tex]\boxed { \text{Lateral surface area = (a + b + c)*h }}[/tex]
= ( 17 + 15 + 8 ) * 18
= 40 * 18
= 720 in²
[tex]\boxed { \text{total surface area = LSA + 2* area of base triangles}}[/tex]
[tex]\text{ area of base triangles = 2* $ \dfrac{1}{2}*base*height $}[/tex]
= base * height
= 8 * 15
= 120 in²
Total surface area = 720 + 120
= 840 in²

Given:
-8x-5(1-x)=6x-2
Solve:
Expand : -8x - 5(1-x) : -3x -5
-3x - 5 = 6x -2
Add 5 to both sides (Balance)
-3x-5+5=6x-2+5
Simplify
-3x = 6x + 3
subtract 6x to both sides (Balance)
-3x - 6x = 6x +3 -6x
Simplify
-9x = 3
Divide both sides by -9 (Balance)
-9x/-9=3/-9
Simplify
x = -1/3

For what values of "x" is the inequality 3(x+2)-x<8 true?
x > 1
x < 1
x < 7
x > 7
We can't determine right off the bat what values of x make this inequality true, so we should solve it first.
First, use the distributive property and distribute 3 :
3(x+2)-x<8
3x+6-x<8
Now subtract 6 on both sides :
3x-x<8-6
3x-x<2
now , subtract the x's :
2x<2
Divide by 2 on both sides :
x<1
So the values of x less than 1 make this inequality true.Let's try -1 (-1 is less than 1)
Plug it in ↓
3(-1+2)-(-1)<8
3(1)+1<8
3+1<8
4<8
4 is less than 8.
Therefore, the values of x that make this inequality true are indeed less than 1.hope helpful ~
Answer:
x < 1
Step-by-step explanation:
Expand the brackets: 3 * x = 3x and 3 * 2 = 6
Current inequality: 3x + 6 - x < 8
Collect like x terms: 3x - x = 2x
Current inequality: 2x + 6 < 8
Collect like integer terms: subract 6 from both sides
Current inequality: 2x < 2
Convert 2x to x: divide both sides by 2
Final answer = x < 1
Hope this helps :)
