A chord subtends an angle 120° at the centre of the circle of radius 3.5cm. Find the perimeter of the minor sector.[r=22/7]
Answer:
Step-by-step explanation:as we know that arc length is
s=r*∅
as given angle in degree so convert it in radian we get
angle=2.09 rad
r=3.5 cm
hence we get
s=3.5*2.09 =7.315 cm
perimeter of sector = s +d where d=2*r=2*3.5=7 cm
perimeter of sector=7.315+7=14.315 cm

Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α

3x=36
x=12°
∡B=2*12+24°=48°
Two fair dice are tossed together once. Find the probability that the sum of the outcome is at least 10
Answer: p = 1/6.
Step-by-step explanation:
First, we have two fair dice, so we have two events.
The number of outcomes for each dice is 6, then the total number of outcomes for the two dice is equal to the product of the number of outcomes in each event.
C = 6*6 = 36.
Now, the combinations that have a sum larger than 10 are:
4 and 6.
6 and 4
5 and 5
5 and 6
6 and 5
6 and 6.
So we have 6 outcomes where the sum of both numbers is larger than 10.
Now, the probability will be equal to the quotient between the number of outcomes where the sum is larger or equal than 10, and the total number of outcomes:
P = 6/36 = 1/6.
James truck shows that his average gas mileage per day is 29 miles per gallon of gas. If james drives about 87 miles each day about how much gas does he use in 14 days of driving
Answer: 42 gallons
Step-by-step explanation:
given data:
average gas mileage/day = 29miles/gallon
distance travelled each day by James = 87miles
How much gas does he use in 14days drive.
solution:
james drives 87miles daily, so in 14 days he would have travelled
= 87miles * 14
= 1218miles travelled.
gas used in 14days
1218miles distance traveled in 14 days
29miles/gallon
= 1218miles / 29miles
= 42gallons of gas have been used by janew to fuel his truck in 14days.
13. Distributive Property
3(x - 1) = 3x - ?
Answer:
[tex]\huge\boxed{3x-3}[/tex]
Step-by-step explanation:
[tex]3(x-1)=\\\\\text{Distribute: }\left \{ {{3*x=3x} \atop {3*-1=-3}} \right.\\\\3(x-1)=\boxed{3x-3}[/tex]
The distributive property is a very important property used in algebra.
It states that when we have the statement a(b + c), we can "distribute" the
a by multiplying a times both terms that are inside the parenthses.
So that would give us a(b) + b(c) or ab + bc.
The same process is done here.
Distribute the 3 through both terms to get 3(x) - 3(1) or 3x - 3.

Answer:
A = 1.11
n = - 6
Step-by-step explanation:
[tex] \frac{0,0001\times 1,11}{0,1\times 10^4} = A \times 10^n\\\\
\frac{1\times 1,11}{1\times 10^4} = A \times 10^n\\\\
\frac{1,11}{10^4} = A \times 10^n\\\\
{1,11\times 10^{-4} } = A \times 10^n\\\\
{1.11\times 10^{-6} } = A \times 10^n\\\\[/tex]
Equating like terms on both sides :
A = 1.11
n = - 6
A 15 foot ladder is leaning against a wall. The foot of the ladder is 7 feet from the wall. How high up the wall is the ladder? Round to the nearest tenth if necessary.
Answer:
13.26
Step-by-step explanation:
The computation of the height should be computed by using the Pythagoras theorem
As we know that
Hypothenuse^2 = base^2 + height^2
where,
Hypothenuse is 15 foot
And, the foot of the ladder i.e base is 7
So now placing these values
The height is
15^2 = 7^2 + height^2
225= 49 + height^2
After solving this, the height is 13.26
c. The cost price of 12 bananas is equal to the SP of 15 bananas.Find loss or gain percent.
Answer:
20% loss.
Step-by-step explanation:
Suppose the cost of each banana is $1
Then cost of 12 = $12.
You sell 15 bananas for $12, therefore the price of each banana is 12/15
= $0.80.
So the loss percent is (1 - 0.80) * 100
= 20%.

Answer:
x = 18
∠A = 83
Step-by-step explanation:
Since you have a line intersecting two parallel lines, the angles formed from the intersection will be equal to 180. This means that you can add up the two angle measures and set them equal to 180.
(6x - 35) + (3x + 53) = 180
6x - 35 + 3x + 53 = 180
9x + 18 = 180
(9x + 18) - 18 = 180 - 18
9x = 162
x = 18
Now to solve for ∠A, plug in the x-value and solve.
∠A = 6x - 35
∠A = 6(18) - 35
∠A = 118 - 35
∠A = 83
The cost to download music from an Internet site is shown.
According to the information in the table, which equation describes the relationship between the number of songs downloaded and the cost to download?
A. c = 1.5n
B. c = 1.5n + 25
C. c = 7.75n
D. c = 7.75n + 25
Answer:
Option (B)
Step-by-step explanation:
If we graph the points given in the table, a straight line is obtained which shows that the table given represents a linear function.
Let the two points on the graph are (4, 31) and (8, 37)
Slope of the line passing through these points,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{37-31}{8-4}[/tex]
= 1.5
Equation of the line passing through a point (4, 31) and slope = 1.5 will be,
y - y' = m(x - x')
y - 31 = 1.5(x - 4)
y = 1.5x - 6 + 31
y = 1.5x + 25
Therefore, Option (B) will be the answer.
One of the digits of a two digit number is three times the other digit. If you interchange the digits of this two digit number and add the resulting number to the original number you get 88 . Find the original number
Answer:
62
Step-by-step explanation:
well, we start by expressing the number:
a b
we understand that using the above expression, the value of the number is 10a + b
using the information in the question,
a = 3b (1)
and,
11b + 11a = 88 (2) (derived using 10a + b form)
hence, when substituting (1) into (2):
11b + 33b = 88
44b = 88
b = 2 (3)
sub (3) into (1)
a = 6
hence, the number is 62
Is 6837 cm less than, greater than or equal to 68hm
Answer:
6837 cm is less than 68 hm
Step-by-step explanation:
1 hectometres = 100 meters
1 centimetres = 0.01 meters
Therefore;
6837 centimetres = 6837 × 0.01 meters = 68.37 meter
6837 centimetres = 68.37 meter
Also, we have;
68 hectometres = 68 × 100 meters = 6800 meters
68 hectometres = 6800 meters
Therefore,
6837 centimetres = 68.37 meter < 68 hectometres = 6800 meters
6837 centimetres < 68 hectometres
6837 cm < 68 hm
6837 cm is less than 68 hm.

Statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.
It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
Thus, statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

Uma barraca de tiro ao alvo de um parque de diversão dará um prêmio de r$ 20ao participante cada vez que ele acertar o alvo por outro lado cada vez que ele errar o alvo da deverápagar r$ 10 não há cobrança inicial para participar do jogo um participante deu 80 tiros e ao final recebeu r$ 100 qual foi o número de vezes que esse participante acertou o alvo
Resposta: 30
Explicação passo a passo:
Dado o seguinte:
Preço para atingir a meta = $ 20
Penalidade por falta de alvo = $ 10
Se 80 tiros forem disparados e os participantes receberem $ 100.
Número de vezes que o participante atinge o alvo.
Deixe o número de erros = m
Deixe o número de acertos = h
h + m = 80 - - - - (1)
20h - 10m = 100 - - - (2)
h = 80 - m
Substitua h = 80 - m em (2)
20 (80 - m) - 10m = 100
1600 - 20m - 10m = 100
-30m = 100 - 1600
-30m = - 1500
m = 50
De (h = 80 - m)
h = 80 - 50
h = 30
Número de acertos = 30
O participante acerta o alvo 30 vezes

Jeremy spends 44 minutes eating dinner with his family. Jeremy finishes eating dinner at 6:09. What time did the clock show when Jeremy started eating dinner?
Answer:
5:25
Step-by-step explanation:
Borrow 1 hour from 6 hours, change it to 60 minutes, and add it to 9 minutes.
6:09 is the same as 5:69.
6:09 = 5:69
Now subtract 44 minutes from 69 minutes.
5:69 = 0:44 = 5:25
Answer: 5:25
Answer:
5:25
Step-by-step explanation:
Borrow 1 hour from 6 hours, change it to 60 minutes, and add it to 9 minutes.

6:09 = 5:69
Now subtract 44 minutes from 69 minutes.
5:69 = 0:44 = 5:25

Answer:
B) 2
Step-by-step explanation:
a3 = 7 , d = -5 (GIVEN)
a4 = a3 + d

Answer:
[tex]\Huge \boxed{a_4=2}[/tex]
Step-by-step explanation:
The third term in an arithmetic sequence is 7.
The common difference is -5.
The common difference of an arithmetic sequence is found by subtracting a term in the sequence with the previous term.
[tex]d=a_4-a_3[/tex]
Solving for the fourth term.
[tex]a_4 = a_3 + d[/tex]
Plugging in the values and evaluating.
