Answer:
it's a translation
Step-by-step explanation:
it just moved (3,0). If it were a rotation the y-axis wouldn't be the same. If it were a reflection you would be able to flip the blue triangle onto the red triangle.

Answer:
There are 42 dogs and 105 cats at the shelter. To find the number of rabbits, subtract these numbers from the total number of animals at the shelter. So there are 21 rabbits at the shelter.
Step-by-step explanation:
Because there are 168 animals at the shelter and [tex]\frac{1}{4}[/tex] of the animals are dogs, you can infer that there are [tex]\frac{168}{4}[/tex] or 42 dogs at the shelter. The question says that [tex]\frac{5}{6}[/tex] of the remaining animals are cats, which you can get two things from this statement: #1, [tex]\frac{5}{6}[/tex] of the remaining animals (not including dogs) are cats in the shelter. #2, [tex]\frac{1}{6}[/tex] of the remaining animals (not including dogs) are rabbits in the shelter, since that is the remaining number of animals left that aren't cats or dogs. Using this, you can get the number of cats is the number of dogs subtracted by the total number of animals at the shelter and multiplied by [tex]\frac{5}{6}[/tex], which would be [tex]\frac{5}{6}[/tex](168 - 42) = [tex]\frac{5}{6}[/tex]*126 = 5 * 21 = 105 cats at the animal shelter. Since the number of rabbits is [tex]\frac{1}{5}[/tex] the number of cats in the shelter ([tex]\frac{5}{6}[/tex] = [tex]\frac{1}{6}[/tex] * 5), that means there are [tex]\frac{105}{5}[/tex] or 21 rabbits at the animal shelter, and that we'd need to subtract the number of cats and dogs from the total number of animals at the shelter to find the number of rabbits.

Find the measure of the indicated angles below.Drag the points to show the measure of the four angles
Answer Plzz
A. Angle E = 113°
B. x = 16°
ExplainNumber A
92 + 70 + 85 + ? = 360
162 + 85 + ? = 360
247 + ? = 360
? = 360 - 247
? = 113°
Number B
108 + 84 + ( x + 30 ) + ( 2x + 18 ) = 360
(180 + 84 + 30 + 18) + (x + 2x) = 360
312 + 3x = 360
3x = 360 - 312
3x = 48
x = 48/3
x = 16°

find CE 14 6 x - 5 2x + 3
The value of x from the similar triangles is x = 9 and the length of CE of the triangle ACE is CE = 35
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔACE
Let the second triangle be represented as ΔBDC
The measure of side AB = 6
The measure of side BC = x - 5
The measure of side AC = x + 1
The measure of side CD = 14
The measure of side DE = 2x + 3
The measure of side CE = 2x + 17
Now , ΔACE and ΔBDC are similar
So , the corresponding sides of similar triangles are in the same ratio
Substituting the values in the equation , we get
AC / CE = BD / CD
( x + 1 ) / ( 2x + 17 ) = ( x - 5 ) / 14
On simplifying the equation , we get
14x + 14 = 2x² - 10x + 17x - 85
Subtracting 14x + 14 on both sides of the equation , we get
2x² - 7x - 99 = 0
On factorizing the equation , we get
x = 9 or x = -11/2
Substituting the value of x in the equation , we get
The length of line segment CE = 2x + 17
The length of line segment CE = 2 ( 9 ) + 17
The length of line segment CE = 35
Hence , the length of CE is 35

Bryson is painting kitchen stools. Each stool requires 1 1/2 liters of paint. Bryson has 20 liters of paint, How many stool will he be able to paint?
Answer:
3
Step-by-step explanation:
5.5 litres paint needed for 1 stool
1 litres paint needed for 1/ 5.5
20 litres paint needed for 20/5.5
= 3.636
And now comes the twist, you can't paint 3.6 stools. also You can't paint 4 stools. You need to round down to 3
(c) Rashid has 210g of cocoa powder and plenty of the other ingredients.
He says that he can make at least 75 cupcakes.
Is he correct?
Explain your reasoning.
Answer:
He is incorrect. He would need 225g of cocoa powder
Step-by-step explanation:
1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.
2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g
Solve for x. Round your answer to the nearest tenth. HELPPPPP!
Answer:
x = 32.6°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{13}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{7}{13}[/tex] ) ≈ 32.6° ( to the nearest tenth )

Find the volume of the cone in terms of pi. 405TT cm3 324TT cm3

The volume of the cone in terms of pi is 324π cubic cm.
What is volume of cone?Volume in mathematics describes how much space a three-dimensional item takes up. It is a measurement of the object's capacity, or the volume of fluid it can store. Typically, cubic units like cubic metres (m3) or cubic centimetres are used to determine an object's volume.
A three-dimensional object's shape affects the formula used to determine its volume. A rectangular prism's volume, for instance, can be determined by multiplying its length, width, and height.
The volume of the cone is given by the formula:
V = (1/3)πr²h
Now, for r = 9 and h = 12 we have:
V = (1/3)πr²h
V = (1/3)π(9²)(12)
V = 324π cubic cm
Hence, the volume of the cone in terms of pi is 324π cubic cm.
