Step-by-step explanation:
a = 7
d = 14-7 = 7
s(50) = n/2*[a+(n-1)*d]
= 50/2*[7+(50-1)*7]

A beach volleyball court is 9 meters wide and 18 meters long. The rope used for the boundary line costs $1.67 per meter. How much would it cost to buy a new boundary line for the court?
Answer:
$90.18
Step-by-step explanation:
Since there are two long sides and two wide sides, you would double them. Add them together, and multiply by price
9 + 9 = 18
18 + 18 36
18 + 36 = 54
54 x 1.67 = 90.18

What is the perimeter of this rectangle pls help
Answer:
24
Step-by-step explanation:
Perimeter of a shape = sum of all lengths of sides
⇒ Perimeter of a rectangle = (2 × width) + (2 × length)
From inspection of the rectangle:
width = 4length = 8⇒ Perimeter = (2 × 4) + (2 × 8)
= 8 + 16
= 24
What is the measure of \angle D∠Dangle, D?
Answer:
74⁰
Step-by-step explanation:
As in cyclic quadrilateral sum of opposite angles us equal to 180⁰
Please help me with this question
Step-by-step explanation:
Insribed angle is half the measure of intercepted arc.
m∠CAB = 1/2mCDBSince O is the center COB is the diameter of this circle.
The diameter splits the circle into two equal arcs. As the full circle is 360°, each semicircle is 180°.
So
1/2mCDB = 1/2(180°) = 90°And the angle measure is
m∠CAB = 90Proved
Answer:
[tex]\overline{\sf COB}[/tex] is the diameter of circle O.
The angle on a straight line is 180° ⇒ ∠COB = 180°
The angle at the center of a circle is twice the angle at the circumference:
⇒ ∠CAB = 1/2 of ∠COB = 1/2 x 180°
⇒ ∠CAB = 90°

Find the value of n x 5 when n=8
Answer:
40
Step-by-step explanation:
Since n=8, then you do 8x5=40.
Answer:
40
Step-by-step explanation:
n x 5
We know what n is equal (8), so we can substitute that number in the given equation.
n x 5 = (8) x 5 = 40
Therefore, the value of n x 5 when n = 8 is 40.

Find the measure of each labeled angle.first,find x=……..,m(angle)A=……,m(angle)B=…..,m(angle)C=……..
Step-by-step explanation:
sum of angles in a straight line is 180°
Therefore,
(3x - 20) + (2x) = 180°
5x =200
x =200/5
x=40°
Angle A=3x - 20
=3(40) - 20
=100°
Angle B=2x
=2(40)
=80°
Angle A=2x - 15
=2(40) - 15
=65°

Marina is spinning a spinner with 15 equal sectors labeled 1 through 15. What is P(factor of 10)? 115 415 13 23
Answer:
4/15
Step-by-step explanation:
Option B is correct, when Marina is spinning a spinner with 15 equal sectors labeled 1 through 15 then P(factor of 10) is 4/15.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that Marina is spinning a spinner with 15 equal sectors labeled 1 through 15.
We have to find the probability P(factor of 10)
The factors of 10 are 1, 2, 5, and 10.
Out of the 15 sectors, there are four sectors that correspond to the factors of 10 (sectors 1, 2, 5, and 10).
Therefore, the probability of landing on a sector that corresponds to a factor of 10 is:
P(factor of 10) = 4/15
Hence, Option B is correct, when Marina is spinning a spinner with 15 equal sectors labeled 1 through 15 then P(factor of 10) is 4/15.

Find the circumferences of both circles to the neartlest tenth
Answer with step by step explanation
First, let us find the circumference of the small circle.
The radius of the small circle is 5 cm.
So, now let us see the formula which is needed to find the circumference.
C = 2 π r
Let us find it now.
Circumference of the small circle.
C = 2 π r
C = 2 × 3.14 × 5
C = 31.4 cm
≈ 30 cm → nearest 10th
Now let us find the circumference of the big circle.
The radius of the big circle is 10 cm.
C = 2 π r
C = 2 × 3.14 × 10
C = 62.8 cm
≈ 60 cm → nearest 10th
You want to rent a car. The cost is $120 per day. You are allowed 100 miles per day--but any mileage above that amount will cost $0.35 per mile. You rent the car for 5 days, and drive 925 miles. The car gets 25 miles to the gallon, and a gallon of gas costs $4.
pls help im so confused
Answer:
600$ rent for 5 days,
around 185 miles a day, meaning you are paying 0.35$x85=29.75 extra a day.
adding up to 120 a day+29.75=149.75 a day.
149.75x5=748.75 for 5 days not including gas prices.
925/25=185 gallons of gas. 4 dollars per gallon, meaning that 185x4=740 extra dollars in gas
748.75+740=1488.75$ for the entire trip.
1488.75

Answer:
49/12
Step-by-step explanation:
1 ⅓ can be written as 1 + 1/3
1 ⅓
= 1 + 1/3
LCM = 3
= 3/3 + 1/3
= ( 3 + 1 )/3
= 4/3
2 ¾
= 2 + 3/4
LCM = 4
= 8/4 + 3/4
= ( 8 + 3 )/4
= 11/4
1 ⅓ + 2 ¾
= 4/3 + 11/4
LCM = 3 x 4 = 12
4/3 x 4/4
= ( 4 x 4 )/( 3 x 4 )
= 16/12
11/4
= 11/4 x 3/3
= ( 11 x 3 )/( 4 x 3 )
= 33/12
16/12 + 33/12
= ( 16 + 33 )/12
= 49/12

Answer:
x^2 - 5x - 66
Step-by-step explanation:
1. Distrubute the x to the x and -11 so you will get x^2 - 11x
2. Distrubute the 6 to x and -11 and you get 6x - 66
3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66
