Figure D’E’F’G’ is a dilation with center (0, 0) of figure DEFG. What is the scale factor?

Answers

Answer 1

Answer:

0,0

Step-by-step explanation:

Answer 2

Answer:

4

Step-by-step explanation:

Lets start by finding out the cordinates first!

these are the ones we start off with!

D (1,1)  

E (2,2)

F (4,2)

G (3,1)

now we need to find the prime image cords.

D' (4,4)

E' (8,8)

F' (16,8)

G' (12,4)

now what we are tying to find is the scale factor, so we need to check what number is multipled by those cordinates to get the prime cordinates.

D is (1,1) and D' is (4,4) but we know that 1x4 is 4 so 4 is the scale factor that we multiply all the numbers by ! i hope that made sense !

Sandy bought 12 7/8 pounds of peaches to make jam. She and her mother ate 0.75 of a pound of the peaches before making the jam. They used 9 3/8 pounds of the peaches to make the jam. How many pounds of peaches were left over?

A. 3 1/4
B. 3
C. 2 3/4
D. 2 1/4

Answers

Answer:

C

Step-by-step explanation:

initial amount: 12 7/8 lbs

ate: 0.75 lbs= 3/4 lbs = 6/8 lbs

used: 9 3/8 lbs

remainder: 12 7/8 - 9 3/8 - 6/8

                = 3  1/8 - 3/8

                =2 6/8 = 2 3/4 = C

therefore C is the answer

Angle 1 is in a triangle with angle 4 and a 53 degrees angle. What is the sum of the measures of those two angles?

Answers

Angle 2=127 because 180-53=127.
Angle 3=23 because 180-30-127=53
Angle 1=37 because 90-53=37
Angle 4=90
Angle 1+4=127

The value of angles are in given triangle as:

Angle 1 = 37°, angle 2 = 127°, angle 3 = 23°, and angle 4 = 90°.

Given that the triangle attached below.

Also given angle one with angle four and a 53° angle.

Since the sum all three angle of triangle is equal to 180°.

In triangle ABC,

∠A + ∠B + ∠C = 180

Angle 1 + 90 + 53 = 180

Angle 1 = 37°

Also the angle 4 is equal to 90°.

The angle 2 is equal to 127°, because 180 - 53 = 127°

Now, in triangle ACD,

∠C=127° and ∠D = 30

∠A + ∠C + ∠D = 180

Angle 3 + 127 + 30 = 23

Hence, the value of angles are:

Angle 1 = 37°

Angle 2 = 127°

Angle 3 = 23°

And angle 4 = 90°

Answers

Answer:

x = 3

Step-by-step explanation:

Solution for 9+5x=24 equation:

Simplifying

9 + 5x = 24

Solving

9 + 5x = 24

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + 5x = 24 + -9

Combine like terms: 9 + -9 = 0

0 + 5x = 24 + -9

5x = 24 + -9

Combine like terms: 24 + -9 = 15

5x = 15

Divide each side by '5'.

x = 3

Simplifying

x = 3

The solution is : in the equation 5x+9=24 the value of x is: x = 3.

Here, we have,

given that,

9+5x=24 is the equation:

suppose you are measuring peanut butter. begin with 1 1/2 c cold water in a container. after you add the peanut butter to the water, the water level reads 2 1/4 c.what is the volume of the peanut butter. explain.

Answers

The answer is the brain

Volume of the peanut butter is 3/4 c.

What is Subtraction?

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Here is given the method to measure the peanut butter.

Volume of the cold water at the  beginning = 1 1/2 c

                                                                        = 3/2 c

Volume of the water after adding the peanut butter = 2 1/4 c

                                                                                       = 9/4 c

Volume of peanut butter = 9/4 c - 3/2 c

                                         = (9/4) - (6/4)

                                         = 3/4 c

Hence the volume of the peanut butter is 3/4 c.

24 divided by 2 and 102 x p

Answer:

39 per pair of pants .

Step-by-step explanation:

First of all you would take 102 and subtract 24 which equals 78 . Then you would divide 78 by 2 and your answer will be 39 . To check your answer you will take 24 39 , 39 and add it all together . if it comes out to 102 you have the correct answer . So you are using subtraction division and addition

Step-by-step explanation:

1. Distribute

2. Add the numbers

3. Order summands

4. Subtract 10 from both sides of the equation

5. Simplify

Answer:

t=2

Step-by-step explanation:

Simplify both sides of the equation.

16=4+3(t+2)

16=4+(3)(t)+(3)(2) (Distribute)

16=4+3t+6

16=(3t)+(4+6)(Combine Like Terms)

16=3t+10

16=3t+10

Step 2: Flip the equation.

3t+10=16

Step 3: Subtract 10 from both sides.

3t+10−10=16−10

3t=6

Step 4: Divide both sides by 3.

Given: AB ≅ BC , AE ≅ FC Prove: m∠AEC=m∠AFC

Answers

Answer:

EC/AB = FC/MA

Step-by-step explanation:

We are given AB

BC that means that side AB and side BC are equal also we know that angle opposite to equalt

sides are equal.

Hence, ∠BAE=∠BCE-------(1)

Also ∠AEB=∠CEB.

Now we are given that: ∠ABC = 130°30’ i.e. in degrees it could be given as:

60'=1°

30'=(1/2)°=0.5°

Hence ∠ABC = 130°30’=130+0.5=130.5°

Also we know that sum of all the angles in a triangle is equal to 180°.

Hence,

∠BAE+∠BCE+∠ABC=180°.

2∠BAE+130.5=180 (using equation (1))

2∠BAE=49.5

∠BAE=24.75°  (DIVIDE BOTH SIDE BY 2)

Now in triangle ΔBEC  we have:

∠BEC=90° , ∠BCE=24.75°

SO,

∠BEC+∠BCE+∠EBC=180°.

Hence, 90+24.75+∠EBC=180

∠EBC=180-(90+24.75)

∠EBC=65.25°

Now we are given AE = 10 in

Also ∠BEA= 90°.

And ∠BAE=24.75°; hence using trignometric identity to find the measure of side BE.

\begin{gathered}\tan 24.75=\dfrac{BE}{AE}=\dfrac{BE}{10}\\\\BE=10\tan 24.75-------(2)\end{gathered}tan24.75=AEBE=10BEBE=10tan24.75−−−−−−−(2)

similarly in right angled triangle ΔBEC we have:

\begin{gathered}\tan 24.75=\dfrac{BE}{EC}\\\\\tan 24.75=\dfrac{BE}{EC}\\\\EC=\dfrac{BE}{\tan 24.75}------(3)\end{gathered}tan24.75=ECBEtan24.75=ECBEEC=tan24.75BE−−−−−−(3)

Hence, using equation (2) in equation (3) we get:

EC=10 \text{in.}EC=10in.

Hence AC=AE+EC=10+10=20 in.

Hence side AC=20 in.
