Answer:

Arc BC is 64°

Step-by-step explanation:

The parameters given are;

∠CAB = 32°

We note that the measure of arc BC = ∠CDB

∠DCA = ∠CAB = 32° (Base angles of an isosceles triangle)

∠ACB = 90° (Angle subtended at the center = Twice angle subtended at the circumference)

∠ACB = ∠DCB + ∠DCA

∴ ∠DCB = ∠ACB - ∠DCA = 90° - 32° = 58°

∠DBC = ∠DCB = 58° (Base angles of an isosceles triangle)

∴ ∠CDB + ∠DBC + ∠DCB = 180° (Sum of interior angles of a triangle)

∠CDB  = 180° - (∠DBC + ∠DCB) = 180° - (58° + 58°) = 64°

∠CDB  = Arc BC = 64°

1 console and 8 games because

Step-by-step explanation:

one console cost 280 and each game costs 25 so do 500-280=220 so, u have 220 dollars left basically. 220/25=8.8 so 8 games u can buy and the tax will be $20 because 0.8 * 25 = 20 so theres ur tax and u have to answer my question

The maximum number of video games Mrs. Sloane can buy is,

⇒ 8

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Mrs. Sloane has $500 to buy a video game console and some video games for her family.

And, Including tax, the video game console costs $280, and a video game costs $25.

Now, Let the maximum number of video games = x

Hence, We can formulate;

⇒ 25x + 280 ≤ 500

⇒ 25x ≤ 500 - 280

⇒ 25x ≤ 220

⇒ x ≤ 8.8

Hence, The maximum number of video games Mrs. Sloane can buy is,

⇒ 8

Answer:

a

Step-by-step explanation:

Given

3(x + 3)² - 81 = 0 ( add 81 to both sides )

3(x + 3)² = 81 ( divide both sides by 3 )

(x + 3)² = 27 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{27}[/tex] = ± 3[tex]\sqrt{3}[/tex] ( subtract 3 from both sides )

x = - 3 ± 3[tex]\sqrt{3}[/tex]

x = - 3 - 3[tex]\sqrt{3}[/tex] or x = - 3 + 3[tex]\sqrt{3}[/tex] → a

36 - 100i² (i² = -1)

36 + 100

136

Answer: 136

Step-by-step explanation:

First, we need to find the conjugate before we can find the product of the conjugate and 6-10i.

The conjugate is the binomial with an opposite sign.

6+10i

Now that we have our conjugate, we can find the product.

(6-10i)(6+10i)                          [distribute the factors, FOIL method]

36+60i-60i-100i²                   [combine like terms]

36-100i²                                  [i²=-1]

36-100(-1)                               [multiply and subtract]

36+100=136

Our product is 136.

Answer:

  B.  One

Step-by-step explanation:

The lines have different slopes, so they must intersect at exactly one point.

There is One solution to this system.

_____

If you solve the first equation for y, you get ...

  y = (5/2)x +2

This has a different slope (x-coefficient) than the second equation does, but it has the same y-intercept. That y-intercept is the point of intersection of the lines, hence the solution: (x, y) = (0, 2).

Answer:

Joseph will have 1,108$ in his bank account when he opens it again.

First, we need to know how much 0.3% of 1000$ is, which is 3$.

Next, since there are 12 months in a year we multiply 3$ by 12 which is 36.

Then, since 3 years have passed we multiply 36$ by 3 which is 108$. So in conclusion, he'll have 1,108$ when he checks his account again.

Answer:

$1,113.87

Step-by-step explanation:

The initial value is 1,000, the rate of increase is 1.003, and the number of times it will increase is 36. y=1000 ( 1.003 ) 36 =1,113.87y equals 1000 left parenthesis 1.003 right parenthesis superscript 36 baseline equals 1113.87.

The sum of the first 50 terms in the sequence 18, 21, 24, 27, ... is 4575.

The sum of the sequence can be calculated by the formula

[tex]S_n = n/2(2a +(n-1)d)[/tex]

where a is the first term, d is the common difference

To find the sum of the first 50 terms in the sequences: 18, 21, 24, 27, ...

[tex]S_n = n/2(2a +(n-1)d)[/tex]

here, a = 18

d = 21 - 18 = 3

n = 50

[tex]S_{50} = 50/2(2(18) +(50-1)3)\\S_{50} = 25(36+147)\\S_{50} = 4575[/tex]

Thus, the sum of the first 50 terms in the sequence is 4575.

Step-by-step explanation:

the triangles are all the same so they are congruent. They are also right triangles so they must be a right triangle the only answer that combine this is b

The green, orange and gray triangles are congruent and right triangles. Thus option B is correct.

Two triangles are congruent triangles if they are of same size and shape.

Right triangle is a triangle with one of angle 90°.

The given triangles of green, orange and gray triangles are of same shape and size . Therefore  we can say that they are congruent triangles

Also we can see that they all have right angle on the left corner therefore they are right triangles . If they are right triangles then they will be also acute triangles too as the some of other two angles of each triangle will be 90 it means they both are less than 90 and congruent means they are similar too as similar triangles have same shape.

Therefore the most appropriate option is Option B , that given triangles are congruent right triangles.

Answer:

z = -12

Step-by-step explanation:

Rewritting the equations, we have:

x + y = xy (eq1)

2x + 2z = xz (eq2)

3y + 3z = yz (eq3)

From the first equation:

x = y/(y-1) (eq4)

From the third equation:

y = 3z/(z - 3) (eq5)

Using the value of y from (eq5) in (eq4), we have:

x = [3z/(z - 3)] / [3z/(z - 3) - 1]

x = [3z/(z - 3)] / [(3z - z + 3)/(z - 3)]

x = 3z / (2z + 3) (eq6)

Using the value of x from (eq6) in (eq2), we have:

6z / (2z + 3) + 2z = (3z / (2z + 3))*z

(6z + 4z^2 + 6z) / (2z + 3) = 3z^2 / (2z + 3)

12z + 4z^2 = 3z^2

z^2 = -12z

z = -12
