In circle o, diameter ADB and chord AC are drawn. Find the measure of arc BC. Please help
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°

Calculate the sum of the first 50 terms in the sequence.
18, 21, 24, 27, ...
Answer:
hope this is correct
The sum of the first 50 terms in the sequence 18, 21, 24, 27, ... is 4575.
What is the sum of the sequence?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.

Two buses are moving towards each other, one at a speed of 40 mph and the other at a speed of 50 mph. How much closer to each other will they be in two hours?
Answer:
180 miles
Step-by-step explanation:
The are moving towards each other at 50 mph and 40 mph which is the same as 90 mph. They are moving 90 mph closer to each other every hour so in 2 hours it would be 180 miles.
Rajesh is working out the area of a circle with radius 10.
he writes:
area = 3.142 x 20
explain why Rajesh's workings are wrong?
Answer:
Rajesh applied the wrong formula
Step-by-step explanation:
The problem is on mensuration of flat shapes, circles.Rajesh applied the wrong formula for the calculation of the area of a circle
he used [tex]area= \pi d[/tex]
Rajesh is expected to solve for the area of a circle using the right formula, which is

b. X = -3 -6 sqrt 3 or -3 + 6 sqrt 3 d. 3 sqrt 3 or -3 + 3 sqrt 3
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

Encouraged by his investment, Joseph decides to open another CD account. This time, he deposits $1,000 and plans to leave it
untouched for 3 years. In exchange, the bank will pay him 0.3% interest every month. How much will be in the account when the 3
years have passed?
Answer:
Joseph will have 1,108$ 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.

Find the product of (6-10i) and it’s conjugate.
Product = ?
FYI: the answer is not 6-10i or 6+10i
Answer:
136
Step-by-step explanation:
(6-10i)(6+10i)
36 +60i - 60i - 100i²
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.

Amanda is running a mile in gym class. She runs at a pace of 5 minutes per mile. What's the dependent variable in the situation?
The system of equations
(xy)/(x+y)=1, (xz)/(x+z)=2, (yz)/(y+z)=3 has exactly one solution. What is $z$ in this solution?
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

What is Inequality?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,

A = P ( 1+r/n)^ nt
Where A is the amount in the account
P is the principal
r is the rate
n is the number of compoundings per year
t is the years
A =3000 ( 1+.10/2)^ 2*10
A =3000 ( 1+.05)^ 20

How many solutions does the following system of equations have?
2y= 5x+4
y= 3x+2
Α. Two
B. One
C. Zero
D. Infinitely many
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).

Which statement is true about the green,orange,and gray triangles show in the textile pattern below?
A. They are congruent obtuse triangle
B. They are congruent right triangle
C. They are acute right triangle
D. They are similar right triangle
Answer:
b
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.
What are congruent triangles and right triangle?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.
