Answer:

D) 112°

Step-by-step explanation:

Reflection is the process in which a given figure is flipped over a given line or point to produce its image. Thus changing the orientation of the initial figure. Rotation involves the turning of a figure with respect to an origin.

The given question involves composition of two reflections on intersecting lines l and m. When a given point or figure is reflected on two intersecting lines, the process is the same as a clockwise rotation of the point or figure twice the intersecting angle.

The reflection of the given point along l and then m will cause a 112° rotation.

Answer:

Hey there!

We have the absolute value of x is greater than two.

Thus, to solve absolute value inequalities, we want to break the inequality down.

We break this down to

x>2

x<-2

Thus, we don't need to simplify this any further, and have our answer.

Hope this helps :)

Answer:

x >= 2 or x <= -2

Step-by-step explanation:

|x|>= 2

Means the absolute value of x is greater than or equal to two.

When we deal with absolute value, we can equivalently break into two cases

+x >= 2    => x >= 2

-x >= 2    =>  x <= -2

On the number line it looks like what is shown in the attached figure.

Answer: There are ways now to get from Andy's house to Willie's house.

Step-by-step explanation:

Given, from Dan's ranch one road is built to get to Andy's house and two roads are built to get to Willie's house.

Then, the number of ways to get from Andy's house to Willie's house =

(Number of ways to Andy's house) x (Number of ways to get Willie's house)   [Using fundamental counting principle]

= 1 x 2 = 2

Hence, there are ways now to get from Andy's house to Willie's house.

Work Shown:

He eats ten 12-calorie crackers, so that is 10*12 = 120 calories total

If x is the number of 20-calorie cookies, then the total number of calories here is 20x. We want this to be 120, so,

20x = 120

x = 120/20 .... divide both sides by 20

x = 6

He must eat six 20-calorie cookies to get 120 calories total

Answer: 6 cookies

Step-by-step explanation:

First, multiply 10*12 to see how many calories he normally eats.

10*12 = 120

Then, divide by 20 to see how many cookies he can eat to keep the same number of calories.

120/20 = 6

Answer:

Area of the rhombus=840

Step-by-step explanation:

Perimeter of a rhombus=4a

148=4a

a=148/4

=37

a=37

The diagonal divides the rhombus into two congruent triangle,

Each congruent triangle= 37 x 37 x 24.

To get the area of the rhombus, we will find the area of one of the congruent triangle, then multiply by 2.

Using Hero's formula to find the area of a triangle, we will use the three sides

Area = √[ s(s-a)(s-b)(s-c) ]

where a, b, and c are the lengths of the three sides: a = 37, b = 37, and c = 24.

s=semiperimeter

s = (a + b + c) / 2

= (37 + 37 + 24)/2

= 98/2

= 49.

s=49

Substitute all the values into the formula

Area = √[ s(s-a)(s-b)(s-c) ]

= √[ 49(49-37)(49-37)(49-24) ]

=√[ 49(12)(12)(25) ]

=√[49(3600)]

=√(176,400)

= 420

Area of one triangle=420

Area of a rhombus=Area of one triangle×2

=420×2

=840

Answer:

840

Step-by-step explanation:

The four sides of a rhombus all have equal length, so if the perimeter is 148, then each side has length 148/4 = 37. Also, the diagonals of a rhombus bisect each other at right angles, so the diagonal of length 24 is cut into two pieces of length 12. We can show this information in a diagram (shown below.)

Applying the Pythagorean Theorem to any of the four right triangles in our diagram, we have

12² + x² = 37².

Solving this equation for positive x, we get x = √37² - 12² = √1369 - 144 = √1225 = 35. The length of the long diagonal is x + x = 70.

The area of a rhombus is half the product of its diagonals. In this case, that is 24 ∙ 70/2 = 12 ∙ 70 = 840.

Answer:

(-2, 21) and (8, 8)

Step-by-step explanation:

Use the two coordinate pairs (-2, 21) and (8, 8).  As we go horizontally from the first to the second, the run (change in x) is 10 and the rise (change in y) is -13.  Thus, the slope of the line through (-2, 21) and (8, 8) is m = rise / run = -13/10.

The equation of this line follows y - k = m(x - h):

y - 8 = (-13/10)(x - 8)

Answer/Step-by-step explanation:

The conditions where we are allowed to subtract or add radicals together is when the radicands, which is the number inside the radical, of both radicals are the same. And also, when they both have the same indices, that is, for example, they have the same root.

Take for example the following radical expression:

[tex]4\sqrt{2} + 3\sqrt{2}[/tex]

Both radicals, [tex]4\sqrt{2} and 3\sqrt{2}[/tex], have the same radicand, [tex]\sqrt{2}[/tex] , and also the same index of square root.

Therefore, they are regarded as like terms, and can be added or subtracted together.

Thus,

[tex]4\sqrt{2} + 3\sqrt{2} = 7\sqrt{2}[/tex]

Answer:

x + y = 6,000

0.025x - 0.015y = 110

Step-by-step explanation:

Let x and y = amount of money deposited in each account respectively

Total savings=$6,000

Therefore

x+y=6000

x account earns 1.5 percent interest, and y account earns 2.5 percent interest.

1.5% * y

=(1.5/100)y

=0.015y

2.5% * x

=(2.5/100)x

=0.025x

The interest in the account that earned 2.5 percent was $110.00 more than the other account.

This means the difference between 0.025x account and 0.015y account=110

0.025x-0.015y=110

x + y = 6,000

0.025x - 0.015y = 110

Answer: The answer is C: x + y = 6,000. 0.025 x minus 0.015 y = 110.

Answer:

[tex]y = 181.75xz^2[/tex]

Step-by-step explanation:

Given

y jointly varies to x and z^2

Required

Find the equation

We start by writing out the variation;

[tex]y\ \alpha\ xz^2[/tex]

Write as equation

[tex]y = kxz^2[/tex]

Substitute values of x,y and z

[tex]70 = k * 21 * 25^2[/tex]

[tex]70 = k * 21 * 25 * 25[/tex]

[tex]70 = k * 13125[/tex]

Divide both sides by 7

[tex]\frac{70}{13125} = \frac{k * 131251}{13125}[/tex]

[tex]\frac{70}{13125} = k[/tex]

[tex]187.5 = k[/tex]

[tex]k = 181.75[/tex]

Substitute k in [tex]y = kxz^2[/tex]

[tex]y = 181.75xz^2[/tex]

Answer:

The value of the given expression is - 1

Step-by-step explanation:

I believe you meant this expression to be iº [tex]*[/tex] i¹ [tex]*[/tex] i² [tex]*[/tex] i³ [tex]*[/tex] i⁴. If that is so, then we can assume that i = imaginary number, and solve for the value of the expression.

Anything taken to the power of 0 is 1, therefore we can simplify the expression as such,

1 [tex]*[/tex] i¹ [tex]*[/tex] i² [tex]*[/tex] i³ [tex]*[/tex] i⁴ ... at the same time anything taken to the power of one, is simply the base value, so -

1 [tex]*[/tex] i [tex]*[/tex] i² [tex]*[/tex] i³ [tex]*[/tex] i⁴ ... we know that multiplying values of like bases can be combined by adding their exponents, so let's apply that rule -

1 [tex]*[/tex] i¹⁰ ... let's break i¹⁰ into ( i² )⁵. i² is, in other words, - 1 applying the imaginary number rule. Respectively ( - 1 )⁵ = - 1, our solution.

Hi

An inverse variation is of the  form  :  f(x) = k/x  where k is a number  and x the variable.

In a inverse variation , the product of   x*y  is for all point always the same which is  K  

so  2*8 = 16    so K = 16  and  f(x) = 16/x

if x = 3  then   f(x) = 3   so :   16/x = 3  ;   3x = 16  ; x ⇒ 16/3

Answer:

6[tex]cm^{2}[/tex] (assuming the units is in centimetres)

Step-by-step explanation:

Hi, hope this helps!

Method 1:

Calculate this shape as a trapezium. This is a trapezium because it has one pair of parallel sides. The way to calculate the area of a trapezium is this:

- Half the sum of the parallel sides

- Multiply the perpendicular height between them

In this case, 4 and 2 are parallel, so we add them together (4 + 2 = 6) then we divide by two (6 ÷ 2 = 3). Then we multiply our answer by the perpendicular length between the two parallel sides (assuming the side on the left is at a right-angle, 3 x 2 = 6).

Method 2:

Calculate this shape as a rectangle + a triangle. If you split the shape so the pointy bit on the right becomes a triangle and the left becomes a square, you can calculate the area without knowing the formula for calculating a trapezium (see above ^).

- Area of the square / rectangle = length x width = 2 x 2 = 4

- Area of the triangle = 1/2 x length x width = 2 x 2 x 1/2 = 4 x 1/2 = 4 ÷ 2 = 2

Then we add the two areas together (4 + 2 = 6).
