Answer:

Dilation

Step-by-step explanation:

A dilation is a type of transformation that changes the size of the image. The scale factor measures how much larger or smaller the image is.

In this example, ΔABC is dilated as seen in the picture because it the picture itself got bigger.

The image, ΔADE is now a dilated version of the pre-image ΔABC

Answer:

square root of area of Q : square root of area of R

Step-by-step explanation:

Area of rectangle= L×B

Area of redrawn rectangle= l×b

ratio of area of two rectangles= (L×B)/(l×b)

ratio of sides of two rectangles=√((L×B)/(l×b))

Answer:

38 and 39

Step-by-step explanation:

Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:

x+(x+1)=77

2x+1=77

2x=76

x=38

x+1=39

Hope this helps!

Answer:I believe it is 39 and 38

Step-by-step explanation:

x + (x+1) = 77

2x = 76

x = 38 (1st number)

x+1 = 39 (2nd number)

Answer:

1/12

Step-by-step explanation:

1/6 times 1/2 is 1/12

1/6 because if the first number is 6 then it is 1/6 since there are only 6 of them

1/2 because there are 3 odd numbers and 3/6 is simplify to 1/2

Answer:

1 1/2

Step-by-step explanation:

1/6*1/2

Answer:

-2 inches

Step-by-step explanation:

Change in height: -10 inches

Days over which change noticed: 5 days

Change per day: -10÷5= -2 inches

The snowman shrank -2 inches per day.

Answer:

Applying the binomial theorem

[tex]{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}[/tex]

Here we have x = -[tex]\sqrt{2}[/tex], n = 8,

=> 4th term (k = 3) would be:

[tex]{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}[/tex]

Answer:

1

Step-by-step explanation:

Plug in -2.

f(x) = -6+7

f(x) = 1

The value of the given function when x is -2 is 1.

A function is defined as a relation between a set of inputs having one output each.

Given a function,  f(x) = 3x + 7

Put x = -2.

f(-2) = -6+7

f(-2) = 1

Hence, The value of the given function when x is -2 is 1.

Answer:

The answer is is

C. $1,627.56

Step-by-step explanation:

The question is incomplete,

Kindly find attached the diagram of the poll for the dimension for your reference.

we need to first calculate the area of the pool.

Let's begin by calculating the area of the rectangular shape

A= length x width

A= 25*15

A=375ft²

Secondly the two semi circles can be solved for as a whole circle

Area of circle = πr²

Radius r= diameter/2= 15/2= 7.5ft

Area = 3.142*7.5²

A= 3.142*56.25

A= 176.7375ft²

Total surface area pool =

176.7375+375= 551.7ft²

Given that a square foot is $2.95

Hence the cost of covering the pool is 551.7*2.95=$1,627.515

Answer:

4a ) Difference ⇒ $ 63.24,

4b ) 4 children

Step-by-step explanation:

4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;

y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,

y = 42.16 + 85.15 ⇒ Combine like terms,

y = 127.31

If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;

y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,

y = 105.4 + 85.15 ⇒ Combine like terms,

y = 190.55

Difference; 190.55 - 127.31 = 63.24,

Solution; Difference ⇒ $ 63.24

4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;

169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,

21.08x = 84.32 ⇒ Divide either side 21.08,

x = 4 children

Solution; 4 children

Answer:

your answer is 9.7 feet

Step-by-step explanation:

you apply Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex] since you are looking for height you can subsitute x for a or b and since 12 is the largest number this will be your c which is your hypotneuse and 7 will be subsituted as a or b depending on what letter you used as your x value [tex]7^{2} +b^{2} =`12^{2}[/tex] is equal too 49 +b^2 =144 you then subtract 49 on both sides to isolate your x (b) and this gets you 95 and then you find the square root of 95 which is 9.7

Answer:

B. 85*

Step-by-step explanation:

1. Understand that a triangle always has the additive degrees of 180.

2. Use x+55+40=180, to isolate x, subtract 55 and 40 from 180.

3. You get x = 85.

Answer:

B. 85 degrees

Step-by-step explanation:

According to the Triangle Sum Theorem, all the angles inside a triangle equal 180 degrees. The work is below:

180-40-55=85. The angle missing is 85 degrees.

-4ab+-4a+-3

Step-by-step explanation:

(5ab-4a-8)-(9ab-5)

distribute the negative sign

=5ab-4a-8+-1(9ab)+(-1)(-5)

=5ab+-4a+-8+-9ab+5

combine like terms

=(5ab+-9ab)+(-4a)+(-8+5)

=-4ab+-4a+-3

Answer:

w = 2.5 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 5 and h = 6, thus

A = 0.5 × 5 × 6 = 15 cm²

Thus the area of the rectangle is 15 cm²

A = lw ( l is the length and w the width )

Here l = 6 and w is to be found

6w = 15 ( divide both sides by 6 )

w = 2.5 cm
