Find x and y
Help me please
Answer:
x = 70 y = 140
Step-by-step explanation:
Apologies if I get any names of vocabulary terms wrong, I never pay much attention to the names.
The central angle measure of an arc is the same as the arc's measure. In this case, y is the central angle and 140 is the arc's measure, so y = 140.
The inscribed angle measure of an arc is 1/2 the arc's measure. An inscribed angle lies on the circle. So 140/2 = 70 = x.

Which two sets of angles are corresponding angles?
O
Answer: ∠p and ∠s, ∠q and ∠r
Step-by-step explanation:
From the lines on the angles indicate which ones are corresponding, for example angles p and s both have 2 lines, while angles q and r both have one line.
The sets of angles are corresponding angles are; ∠p and ∠s, ∠q and ∠r
What are corresponding angles?It can be defined as, corresponding means pair wise angles. Like the right corner angles of two triangles etc. But usually we take them as:
For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of same measurement.
From the lines on the angles indicate which ones are corresponding, for example angles p and s both have 2 lines, while angles q and r both have one line.
We can conclude the sets of angles that are corresponding angles;
∠p and ∠s, ∠q and ∠r

A man borrows $800 for 2 years at a simple interest rate of 20%. What is the total amount that must be repaid
Answer: [tex]\$1120[/tex]
Step-by-step explanation:
Given
Man borrows $800 for 2 years
Rate of interest is R=20%
Simple interest is given by
[tex]\Rightarrow S.I.=\dfrac{P\times R\times T}{100}[/tex]
Insert the values
[tex]\Rightarrow S.I.=\dfrac{800\times 20\times 2}{100}\\\\\Rightarrow S.I.=\$320[/tex]
So, total payable amount is

A line with a slope of 3 passes through the point (-1, 2).
Write an equation for this line in point-slope form.
Answer:
Step-by-step explanation:
Slope = m = 3
(x₁ , y₁) = (-1 , 2)
Point slope form: y - y₁ = m(x - x₁)
y - 2 = 3(x - [-1] )
y - 2 = 3(x + 1)
y - 2 = 3*x + 3*1
y - 2 = 3x + 3
y = 3x + 3 + 2
y = 3x + 5

Martin was selling tickets for a basketball game in a high school. He sold
1,250 tickets and the total amount collected for the game was $2,750. The
student tickets cost $2 each, and adult tickets cost $3 each. How many
student and adult tickets were sold?
Answer:
1,000 student tickets.250 adult tickets.Step-by-step explanation:
2x + 3y = 2750
x + y = 1250
where x is student tickets and y is adult tickets
x = 1250 – y
2x = 2500 – 2y
→
(2500 – 2y) + 3y = 2750
2500 + y = 2750
y = 250 →
x + y = 1250
x = 1000

razones y proporciones. un pelotero profesional ha bateado 14 imparables , en 40 turnos al bate . hallar la razón entre las veces que ha bateado de imparable y los turnos que ha tenido que batear.
Answer:
El pelotero ha bateado imparables en el 35% de sus intentos.
Step-by-step explanation:
Dado que un pelotero profesional ha bateado 14 imparables en 40 turnos al bate, para hallar la razón entre las veces que ha bateado imparables y los turnos que ha tenido que batear se debe realizar el siguiente cálculo:
14 / 40 = X
0.35 = X
0.35 x 100 = 35
Por lo tanto, el pelotero ha bateado imparables en el 35% de sus intentos.
Q2: 8,15,22,29,36,............ A sequence of numbers is shown above. a) Find the 10th term of the sequence. *
This is a required question
b) Find the nth term of the sequence. *
c) Which term of the sequence is equal to 260. *
Answer:
a) 71
b) an = a1 + (n-1)×7
c) the 37th term
Step-by-step explanation:
clearly, an+1 = an + 7
so, any new term is the previous term plus 7.
a1 = 8
and then the sequence goes on. starting with a2 we add 7 every time.
so, for an we added 7 n-1 times to a1. n-1 because for a1 we did not have to add 7.
therefore, the building function of this sequence to calculate the nth term is
an = a1 + (n-1)×7
a10 = a1 + 9×7 = 8 + 63 = 71
and
ax = 260 = a1 + (x-1)×7 = 8 + 7x - 7 = 1 + 7x
259 = 7x
x = 37
=> the 37th term of the sequence is 260

[tex]108 in^{2}[/tex]
Step-by-step explanation:
[tex]===========================================[/tex]
Formulas:
Area of a rectangle/square:
[tex]A=lw[/tex]
Area of a triangle:
[tex]A=bh\frac{1}{2}[/tex]
[tex]===========================================[/tex]
To find the square, length*width. Both the length and width are 6, so the area of the square is 36 in.
The triangles all have a base of 6 and a height of 6. So, 36 divided by 2 or multiplied by [tex]\frac{1}{2}[/tex]
You would get 18 in.
There are 4 triangles, so multiply 18 by 4. 72 in.
Add up 36 and 72.

Can someone help me with this math homework please!
Answer:
x = 12
Step-by-step explanation:
First we need to add x & 1/4x.
Pretend there's a 1 infront of x, so that the equation looks like:
1x + 1/4x = 15
To combine the two terms, we need to get the 1 to have the same denominator as 1/4, so let's multiply 1 (which is the same as 1/1) by 4/4.
You get 4/4! Substitute that into the equation:
4/4x + 1/4x = 15
Now combine the terms:
(4/4x + 1/4x = 5/4x)
5/4x = 15
Finally, multiply both sides by 4/5 to cancel out the 5/4:
x = 15*4/5
x = 60/5
x = 12

what is the length of segment QV ?, NO LINKS.
Answer:
44 units
Step-by-step explanation:
TS = TQ
2x + 8 = 40
2x = 32
x = 16
QV = SV
QV = 3x - 4
QV = 3(16) - 4
QV = 48 - 4
QV = 44
Equation for the length of a rectangle is two more than three times the width area is 161
Answer:
l = 3w+2
l = 23
Step-by-step explanation:
The area of a rectangle is
A = lw where l is the length and w is the width
l = 3w+2
A = 161
161 = (3w+2) *w
Distribute
161 = 3w^2 +2w
Subtract 161 from each side
0=3w^2 +2w -161
Factor
0=(w-7)(3w+23)
Using the zero product property
w-7 =0 3w+23 =0
w=7 w = -23/3
Since the width cannot be negative
w=7
l = 3w+2
l = 3(7)+2
l = 21+2 = 23
Length = 3w + 2 = 23.
Step-by-step explanation:
Given :-
The length of a rectangle is two more than three times the width = ( 3w + 2 )Let width of rectangle be w.Area of rectangle = 161.Find :-
Length of rectangle .Solution :-
We know that ,
Area of rectangle = Length × Width.
Substitute the values161 = (3w + 2) × w
Distribute w .161 = 3w² + 2w
Move constant to the left-hand side and change their signs.0 = 3w² + 2w - 161
Split the middle term- 2w as 23w - 21w.0 = 3w² + 23w - 21w - 161.
Factor out w from first pair and -7 from second pair.0 = w ( 3w + 23 ) -7 ( 3w + 23)
Factor out 3w + 23.0 = (3w + 23 ) ( w - 7)
Using zero product property.w - 7 = 0 , 3w + 23 = 0
Solve for w.w = 7 , w = -23/3
Since, width of rectangle can't be negative.
so, w = 7 is right value of width.
Calculate for Length.
length = 3w + 2 ( plug the value of width)
length = 3 ( 7 ) + 2 Length = 21 + 2Hence, length = 23
