Estimate the number of boys at Hillview.

Answer:

Triangle HBN ~ triangle LYR

=> HN/LR = HB/LY

=> (3x - 7)/(x + 11) = 28/21

=> 21(3x - 7) = 28(x + 11)

=> 63x -147 = 28x + 308

=> 35x = 455

=> x = 455/35 = 13

There is no answer to select. But I still believe there is no mistake in my calculation.

Hope this helps!

Answer:

k=16

Step-by-step explanation:

To solve this, we can isolate k.

40+k=56.

We can do this by subracting 40 from both sides.

40+k-40=k

56-40=16

k=16

First isolate or get k by itself by subtracting 40 from both sides.

That leaves us with k = 16.

To check our answer, substitute 16 back into the equation.

So we have 40 + (16) = 56 or 56 = 56.

There are 3 Answers:

Choice A) reflect the dilated circle over the horizontal line through point C.

Choice D) rotate the dilated circle 180 degrees around point C

Choice E) translate the dilated circle to center B

Due to symmetry, rotations and reflections do not change a circle. This is why we are able to rotate around point C so that it looks like a translation has occurred. A similar thing happens with reflections as well.

The correct Answers:

A) reflect the dilated circle over the horizontal line through point C.

D) rotate the dilated circle 180 degrees around point C

E) translate the dilated circle to center B

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.

Given is circle A is dilated so that it is the same size as circle B, we need to determine the transformations performed to show that the circles are similar.

We know that,

Due to symmetry, rotations and reflections do not change a circle.

So, rotate around point C so that it looks like a translation has occurred.

A similar thing happens with reflections as well.

Hence, the correct options are A, D and E

135 gallons of water in the aquarium after 45 minutes of draining.

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that water is draining from an aquarium at a rate of 3 gallons per minute.

The total change in the amount of water in the aquarium after 45 minutes of draining is as:

⇒ 45×3

Apply the multiplication operation in the integers,

⇒ 135 gallons

Hence, 135 gallons of water in the aquarium after 45 minutes of draining.

Answer:

9π/4 - 4.5 unit^2.

Step-by-step explanation:

The are of the segment = area of the sector - area of the triangle.

Area of the sector = 1/4 * area of the circle

= 1/4 π 3^2

= 9π/4. unit^2

Area of the triangle

=  1/2 * 3 * 3

= 9/2 unit^2.

So the answer is 9π/4 - 4.5 unit^2.

Answer:

f(x+1)=(5/6)f(x)on:          Five-sixths Superscript f (x)

EXPLANATION:

The defining characteristic of a geometric sequence is that each term is a constant multiple of the previous term, called the common ratio denoted r in the rules for geometric equations.

625/750=750/900=etc=r=5/6

The function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

A geometric sequence is a sequence such that -

a(n + 1)/a(n) = K {constant}

[K] is called common ratio.

Given is a graph representing a geometric sequence.

Now, for -

f(2) = 1080

and

f(1) = 1296

So -

f(2)/f(1) = 1080/1296 = 5/6

In general -

f(x + 1)/f(x) = 5/6

f(x + 1) = 5/6 f(x)

Therefore, the function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).

Step-by-step explanation:

edge 2022 :) I hope I helped a bit credit to the comment above me

The number of tiles he will need 42.

The area of a parallelogram is the product of the base and the height of the figure.

The area of a parallelogram = Base x Height

We are given that top of the table measures 18 inches by 14 inches. If each tile has four sides of length 3 inches with a height of 2 inches.

Area of table =  Base x Height

= 18 x 14

= 252

Area of glass parallelogram tiles = Length x width

= 3 x 2

= 6

Now,

252 = 6 x number of tiles

number of tiles = 252 / 6

= 42

Step-by-step explanation:

the answer is, no.. she is not correct.

she solved the equation/question incorrectly.

why? Shauna subtracted 9 - 12/3 = 5

she multiplied 5 and 2 = 10

then subtracted by 6.

so she got 4.

but, this how you do it.

subtract 9 and 6, equaling 3.

Answer:

A

Step-by-step explanation:

Whenever you square a real number, the result will always be positive, because even if you are squaring a negative number a negative times a negative is a positive. However, when you cube a negative number, the result CAN be negative, because you are multiplying a negative number by itself three times. Therefore, the answer is only A. Hope this helps!

Answer:

x = 17°, m∠ A = 114°

Step-by-step explanation:

We can tell that these pair of angles are corresponding, provided;

Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,

m∠ A = m∠ B ⇒ Substitute values of A and B,

6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,

3x + 12 = 63 ⇒ Subtract 12 on either side of equation,

3x = 51 ⇒ Divide either side by 3,

x = 17 ⇒ Substitute value of x to solve for m∠ A,

m∠ A = 6 * ( 17 ) + 12,

m∠ A = 102 + 12,

m∠ A = 114

Solution; x = 17°, m∠ A = 114°

Answer:

x = 17, ∠A = 114°

Step-by-step explanation:

I'm 8 years old and I know how to do this.

6x + 12 = 3x + 63

3x + 12 = 63

3x = 51

x = 17

6(17) + 12

102 + 12 = 114
