Can someone help me with this question.

Answer:

m∠XZY = 122°

m∠XWY = 61°

Step-by-step explanation:

From the picture attached,

A circle has been given with center as Z.

∠XZY is a central angles subtended by the arc XY,

Therefore, measure of angle XZY will be equal to measure of ∠XZY.

m(∠XZY) = m(arc XY) = 122°

By another property of the circle,

"Inscribed angle measures the half of the central angle intercepted by the same arc."

Therefore, m∠XWY = [tex]\frac{1}{2}(\angle XZY)[/tex]

                                 = [tex]\frac{1}{2}(122)[/tex]

                                 = 61°

Answer:

336 ft^2

Step-by-step explanation:

All you have to do is find the area of each face, and add them up.

Firstly lets starts with the identical triangles.

There are two of them, and the area of a triangle is b*h/2

So the area is 6*8/2 , which is 24, and since their are two of them, we add another 24, and we get 48 so far.

Since all the other sides are rectangles, we can just multiply the given lengths and add them up.

So, we have

12x10, which is 120,

12x8, which is 96, and

12x6, which is 72.

Now add all of them up.

48+120+96+72 which is 336

Your answer is 336 ft^2

I don't have a grid with me but look at it this way. if you look at the first set of points look at where they are starting. and. then look at the second set of points. see if the points plotted bend over the x axis or the y axis:)

Answer:

35x² + 29x - 30

Step-by-step explanation:

Given

25x² + (5x - 3)(2x + 7) - 9 ← expand factors using FOIL

= 25x² + 10x² + 29x - 21 - 9 ← collect like terms

= 35x² + 29x - 30

Yes, it is

Step-by-step explanation:

You have to multiply 65 times .0575 to get the amount of money the TAX ALONE will be and you get 3.7375 which rounds up to $3.74 in taxes. Then you add it to the fee to groom the cat and you get $68.74

Answer:

The length of the park is approximately 1.77 kilometers

Step-by-step explanation:

The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known

The given parameters of the question are;

The distance from Mark's house to the edge of the park, a = 0.9 km

The distance from the far side of the park to Mark's house, c = 1.6 km

Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;

b² = a² + c² - 2·a·c·cos(B)

Where;

b = The length of the park in kilometers

By plugging in the known values of 'a', 'b', and 'c', we get;

b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089

∴ b = √(3.11899146089) ≈ 1.76606666377

Therefore, the length of the park, b ≈ 1.77 km.

Answer:

Step-by-step explanation:

3x²+3x-6

=3(x²+x-2)

=3(x²+2x-x-2)

=3[x(x+2)-1(x+2)]

=3(x+2)(x-1)

Answer:

3(x - 1)(x + 2)

Step-by-step explanation:

Factor 3x^2 + 3x - 6

Step 1: Factor out a common factor from all terms if possible.

All terms have a common factor of 3. We start by factoring out the 3.

3x^2 + 3x - 6 =

= 3(x^2 + x - 2)

Step 2: We now need to deal with factoring x^2 + x - 2.

It is a trinomial of the form x^2 + ax + b, where the coefficient of x^2 is 1. To factor it, we need 2 numbers whose product is b and whose sum is a. In our case, we have x^2 + x - 2. We need two numbers whose product is -2 and whose sum is 1.

Pairs of numbers with product -2:

-2 and 1 since -2 * 1 = -2

-1 and 2 since -1 * 2 = -2

Now we add the two numbers in each line above.

-2 + 1 = -1    The sum is -1, but we need a sum of 1, so this is not it.

-1 + 2 = 1     Here we do get the sum of 1 that we need, so this pair of numbers is what we need.

The two numbers we need for factoring are -1 and 2.

Now we start the next step.

The factored trinomial will have this form.

= 3(x     )(x     )

All we need to do now is place each of the numbers in one of the blanks.

= 3(x - 1)(x + 2)

Answer: 3(x - 1)(x + 2)

Step-by-step explanation:

If there are two straight lines the opposite angles equal each other

so 4x+2=150

subtract both sides by 2

4x=148

divide both sides by 4

x=37

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.

Answer:

x = 22°

the angles are: 63° and 117°

Step-by-step explanation:

a linear pair of angles total together to be 180°

so:

3x - 3 + 5x + 7 = 180

combune like terms:

8x = 176

divide both sides of the equation by 8:

x = 22°

the angles are: 63° and 117°

Answer:

x= -1

Step-by-step explanation:

p= x² +4x -2 -----(1)

q= 2x -1 ------(2)

q -p= 2 -----(3)

Substitute (1) and (2) into (3):

2x -1 -(x² +4x -2)= 2

2x -1 -x² -4x +2= 2 (Expand bracket)

-x² -2x +1=2 (Simplify)

x² +2x +2 -1= 0 (Bring all terms to one side)

x² +2x +1= 0

(x +1)²= 0 (Factorise)

x +1= 0 (Square root both sides)

x= -1 (-1 on both sides)

Answer:

45 degrees

Step-by-step explanation:

Each triangle in the figure is at a 45 degree angle to the next one, telling us that if you rotate the entire thing by 45 degrees, it will flip.

Answer:

B. 45 degrees

Step-by-step explanation:

The questions is asking us to find the minimun degrees needed to rotate the shape so that it maps itslef, which is just basically asking us to roate the shape so that it looks the same as it is now. That means that we need to rotate the shape so that another one of those traingles is pointing up. There are 8 of those traingle, and there is 360 degrees in a circle. So divide 360 degrees by 8, and we find that there is 45 degrees inbetween each of the triangles. So if we rotate it by 45 degrees the next traingle will be pointing up and the shape will have mapped itself.

Answer:

$35,100

Step-by-step explanation:

Given data

Principal=$10000

Rate= 8.5%

Time = 15 years = 180 months

The expression for monthly compounded interest is

A=P(1+r/12)^t

substitute

A=10000(1+0.085/12)^180

A=10000(1+0.007)^180

A=10000(1.007)^180

A=10000*3.51

A=$35,100

Hence the balance is $35,100
